Technical Field

The invention relates to a half-shell for a torsion bar bearing, a torsion bar bearing comprising at least two such half-shells and a method for supporting a torsion bar.

Background

The invention belongs to the technical field of torsion bars, in particular to the technical field of bearings for torsion bars. The torsion bar or the torsion bar spring is a rod spring which is designed such that a shear stress is generated in the torsion bar when it is twisted. The support of the torsion bar must therefore be configured to produce a corresponding resistance to the forces generated.

Disclosure of Invention

It is therefore an object of the present invention to provide a half-shell for a torsion bar bearing having a higher radial stiffness and a longer service life.

In particular, this object is achieved by a half-shell for a torsion bar bearing, a torsion bar bearing comprising at least two such half-shells and a method for supporting a torsion bar according to the independent claims, respectively. Preferred embodiments form the object of protection of the dependent claims.

One embodiment relates to a half-shell for a torsion bar bearing, comprising a half-shell body which is designed in one piece and along a body axis, and at least one reinforcing device which is designed to increase the rigidity of the half-shell body. Stiffness is understood in the description as the resistance of the body against elastic deformation due to forces and/or moments. The torsion bar bearing is designed to support at least one torsion bar. The torsion bar bearing is not limited to supporting a torsion bar, but can be used to support any rod. In the operating state of the torsion bar bearing, the half-shell body surrounds the torsion bar at least partially, in particular at least partially radially or circumferentially, based on the torsion bar axis and at least partially axially or along the torsion bar axis. In particular, the half-shell body can be designed to surround, in the operating state, about 50%, less than about 50%, or more than about 50% of the torsion bar in a circumferential direction, based on the torsion bar axis. In other words, the half-shell body can be designed to surround, in the operating state, about 180%, less than about 180%, or more than about 180% of the torsion bar circumferentially, i.e. in the circumferential direction, based on the torsion bar axis.

The half shell comprises a half shell body of one-piece construction, wherein one-piece is understood here to mean constructed in one piece and/or made of one material and/or in one manufacturing step. In particular, the half-shell body can also be of hollow-cylindrical design and have an inner surface and an outer surface. In particular, the body axis can be identical to the central axis of the hollow-cylindrical half-shell body. The inner surface is here the surface of the half-shell body facing the body axis, which surface at least partially surrounds the body axis. The outer surface is here the surface of the half-shell body facing away from the body axis, which surface at least partially surrounds the body axis. At least one of the inner and outer surfaces is preferably substantially continuous, as a result of which the stiffening effect of the half-shell can be improved. The half-shell body also has an end side and a rear side, wherein the end side and the rear side are arranged opposite one another on the half-shell body, and wherein a normal vector of the end side and a normal vector of the rear side are preferably parallel to one another. Furthermore, the normal vector of the front side and/or the normal vector of the rear side are/is configured parallel to the body axis. The length of the half shell corresponds to the distance between the end side and the rear side measured parallel to the body axis or the maximum distance between the end side and the rear side measured parallel to the body axis.

Preferably, the at least one stiffening means comprises at least one inner rib element, wherein the at least one inner rib element is arranged on the inner surface of the half-shell body. The at least one inner rib element extends or is distributed at least partially over the inner surface of the half-shell body and is thereby designed to increase the resistance of the half-shell body against elastic deformation due to forces and/or moments, in particular due to forces and/or moments transmitted or caused by the torsion bars.

In particular, the inner rib elements can be designed as projections or webs which project inwardly from the inner surface of the half-shell body. The inner rib element may also have a height such that the inner rib element protrudes from the inner surface, wherein the height is measured from the inner surface in a radial direction based on the body axis. In particular, the height of the inner rib elements may be constant in a direction parallel to the body axis to achieve uniform stiffness adjustment, or may be variable in a direction parallel to the body axis to achieve locally matched stiffness adjustment.

The inner rib element may also have a rib wall diameter or a rib wall thickness, wherein the rib wall diameter is measured and quantified perpendicular to the radial direction based on the body axis and perpendicular to the body axis. In particular, the rib wall diameter of the at least one inner rib element may be constant in a direction parallel to the body axis to achieve a uniform stiffness adjustment. In particular, the rib wall diameter may have a value of at least about 1mm, preferably at least about 1.5mm and/or at most about 15mm, preferably at most about 10 mm. In particular, the material thickness of the half-shell body can be kept below a threshold value by means of such a configuration of the inner rib elements. By keeping the material thickness, which can correspond to the rib wall diameter, below such a threshold value, the disadvantageous effects based on long injection times can be reduced or avoided when producing thicker half-shell bodies, for example when stretching or deforming the half-shell body.

In particular, the height of the inner rib elements may be constant in the direction of the encircling with respect to the body axis to achieve a uniform stiffness adjustment or variable in the direction of the encircling with respect to the body axis to achieve a locally matched stiffness adjustment. The at least one stiffening device may also have at least two internal rib elements which cross each other.

In particular, the at least one inner rib element can be designed to increase the resistance of the half shell body against elastic deformation due to forces and/or torques, in particular due to forces and/or torques transmitted or caused by the torsion bars, and to prevent or reduce an unintentional stretching or deformation of the half shell body during temperature fluctuations, in particular during the production of the half shell body, for example during the injection of the half shell body.

Preferably, the at least one inner rib element comprises at least one inner axial rib element comprising layers substantially parallel to the body axis. In this case, the at least one inner axial rib element can extend at least partially parallel to the body axis and can thus counteract or reduce or prevent axial deformation of the half-shell body. In particular, the at least one inner axial rib element may extend over the entire length of the half-shell body to achieve a uniform stiffness adjustment of the half-shell body. In particular, the height of the at least one inner axial rib element can be adapted to the local stiffness requirements. In particular, the at least one inner rib element may comprise a plurality, for example 2, 3, 4, 5, 6, 7, 8 or more inner axial rib elements, which may extend along the inner surface of the half-shell body at equal or unequal intervals.

Preferably, the at least one inner rib element comprises at least one inner circumferential rib element which is designed to surround the body axis at least in part circularly. In this case, the at least one inner circumferential rib element can at least partially surround the body axis in a partial circle and can thereby counteract or reduce or prevent radial deformation of the half shell body. In particular, at least one inner circumferential rib element can extend from a first end of the inner surface to a second end of the inner surface opposite the first end, so that a uniform stiffness adjustment of the half-shell body is achieved. In particular, the height of the at least one inner circumferential rib element is adapted to the local stiffness requirement. In particular, the at least one inner rib element may comprise a plurality of, for example 2, 3, 4, 5, 6, 7, 8 or more inner circumferential rib elements, which may extend along the inner surface of the half-shell body at equal or unequal intervals.

Preferably, the at least one inner rib element comprises at least one first inner helical rib element, which is designed to at least partially helically surround the body axis, wherein the at least one inner rib element preferably comprises at least one second inner helical rib element, which is designed to at least partially helically surround the body axis and to cross the at least one first inner helical rib element. In particular, axial and radial deformations of the half-shell body can thereby be counteracted or reduced or prevented. The half-shell body is not limited to this configuration, however, and the at least one inner rib element may have at least two inner helical rib elements which are designed to at least partially helically surround the body axis without crossing.

Preferably, the at least one inner rib element comprises a plurality of inner rib elements, which are arranged along the splicing edges of the inner surface, for example according to a honeycomb pattern. The term joining is understood here to mean mathematically, i.e. covering the inner surface by a partial surface or surface piece, in particular a partial surface or surface piece of the same shape, without gaps or overlaps. The inner surface may be mathematically a euclidean plane for this purpose, for example by unfolding the inner surface around the body axis. This can be shown mathematically, for example, in an X-Y-coordinate system, where the X-coordinate corresponds to the distance along the inner surface parallel to the body axis and the Y-coordinate corresponds to the distance along the inner surface in the direction of the surround based on the body axis. But may also be a projection of the inner surface on the euclidean plane and be known, for example, on the basis of a map projection in a cartographic drawing. Here, the splices may be periodic splices, such as honeycomb models (e.g., based on hexagons), or aperiodic splices, such as penrose splices.

Preferably, the at least one inner rib element can be formed integrally or monolithically with the half-shell body. This makes it possible, for example, to produce the half-shell body in a simple one-step process. In particular, at least one of the at least one inner rib element can be constructed integrally or monolithically with the half-shell body.

Preferably, at least one inner rib element may be mounted on the half-shell body or on the inner surface. The rigidity of the half-shell body can thereby be adjusted by fitting the respective required or required internal rib elements. In particular, the production of the half-shell body and the production of the inner rib elements can thereby be separated from one another, so that the manufacturing process of the half-shell can be designed more flexibly.

Preferably, at least one inner rib element has an at least partially circular and/or at least partially rectangular or rectangular and/or at least partially triangular or triangular and/or at least partially trapezoidal cross-sectional profile. The cross-sectional contour of the inner rib element at a point or at a point is obtained here from the cross-sectional shape of the inner rib element in the cross-sectional plane. The cross-sectional plane is a plane which includes a perpendicular through the respective point on the axis of the body and in which the diameter of the inner rib element perpendicular to the perpendicular is minimized. In particular, the inner rib elements have different cross-sectional profiles at different points along the inner rib elements.

Preferably, the at least one reinforcing means comprises at least one external rib element, wherein the at least one external rib element is arranged on the outer surface of the half-shell body. The at least one outer rib element extends or is distributed at least partially over the outer surface of the half-shell body and is thereby designed to increase the resistance of the half-shell body against elastic deformation due to forces and/or moments, in particular due to forces and/or moments transmitted or caused by the torsion bars.

In particular, the outer rib elements can be designed as projections or webs which project outwardly from the outer surface of the half-shell body. The outer rib elements may also have a height such that the outer rib elements protrude from the outer surface, wherein the height is measured from the outer surface in a radial direction based on the body axis. In particular, the height of the outer rib elements may be constant in a direction parallel to the body axis to achieve uniform stiffness adjustment or variable in a direction parallel to the body axis to achieve locally matched stiffness adjustment.

The outer rib element may also have a rib wall diameter or a rib wall thickness, wherein the rib wall diameter is measured and quantified perpendicular to the radial direction based on the body axis and perpendicular to the body axis. In particular, the rib wall diameter of the at least one outer rib element may be constant in a direction parallel to the body axis to achieve a uniform stiffness adjustment. In particular, the rib wall diameter may have a value of at least about 1mm, preferably at least about 1.5mm and/or at most about 15mm, preferably at most about 10 mm. In particular, the material thickness of the half-shell body can be kept below a threshold value by means of such a configuration of the outer rib elements. By keeping the material thickness corresponding to the rib wall diameter below such a threshold value, the disadvantageous effects based on long injection times can be reduced or avoided when producing thicker half-shell bodies, for example when stretching or deforming the half-shell body.

In particular, the height of the outer rib elements may be constant in the direction of the encircling with respect to the body axis to achieve a uniform stiffness adjustment or variable in the direction of the encircling with respect to the body axis to achieve a locally matched stiffness adjustment. The at least one stiffening device may also have at least two outer rib elements which cross each other.

In particular, the at least one outer rib element can be designed to increase the resistance of the half shell body against elastic deformation due to forces and/or torques, in particular due to forces and/or torques transmitted or caused by the torsion bars, and to prevent or reduce unintentional stretching or deformation of the half shell body during temperature fluctuations, in particular during the production of the half shell body, for example during the injection of the half shell body.

Preferably, the at least one outer rib element comprises at least one outer axial rib element configured substantially parallel to the body axis. In this case, the at least one outer axial rib element can extend at least partially parallel to the body axis and can thus counteract or reduce or prevent axial deformation of the half-shell body. In particular, the at least one outer axial rib element may extend over the entire length of the half-shell body to achieve a uniform stiffness adjustment of the half-shell body. In particular, the height of the at least one outer axial rib element can be adapted to the local stiffness requirement. In particular, the at least one outer rib element may comprise a plurality, for example 2, 3, 4, 5, 6, 7, 8 or more outer axial rib elements, which may extend along the outer surface of the half-shell body at equal or unequal intervals.

Preferably, the at least one outer rib element comprises at least one outer circumferential rib element which is designed to surround the body axis at least in part circularly. In this case, the at least one outer circumferential rib element can at least partially surround the body axis in a partial circle and can thereby counteract or reduce or prevent radial deformation of the half shell body. In particular, at least one outer circumferential rib element can extend from a first end of the outer surface to a second end of the outer surface opposite the first end, so that a uniform stiffness adjustment of the half-shell body is achieved. In particular, the height of the at least one outer circumferential rib element can be adapted to the local stiffness requirement. In particular, the at least one outer rib element may comprise a plurality of, for example 2, 3, 4, 5, 6, 7, 8 or more outer circumferential rib elements, which may extend along the outer surface of the half-shell body at equal or unequal intervals.

In particular, axial and radial deformations of the half-shell body can thereby be counteracted or reduced or prevented. The half-shell body is not limited to this configuration, however, and the at least one outer rib element may have at least two outer, helical rib elements which are designed to at least partially helically surround the body axis without crossing.

Preferably, the at least one outer rib element comprises a plurality of outer rib elements, which are arranged along the joint edges of the outer surface, for example according to a honeycomb pattern. The term joining is understood here to mean mathematically, i.e. covering the outer surface by a partial surface or surface piece, in particular a partial surface or surface piece of the same shape, without gaps or overlaps. The outer surface may be mathematically a euclidean plane, for example by unfolding the outer surface about the body axis. This can be shown mathematically, for example, in an X-Y coordinate system, where the X coordinate corresponds to a distance along the outer surface parallel to the body axis and the Y coordinate corresponds to a distance along the outer surface in a surrounding direction based on the body axis. But may also be a projection of the outer surface on the euclidean plane and be known, for example, on the basis of a map projection in a cartographic drawing. Here, the splices may be periodic splices, such as honeycomb models (e.g., based on hexagons), or aperiodic splices, such as penrose splices.

Preferably, the at least one outer rib element can be constructed integrally or monolithically with the half-shell body. This makes it possible, for example, to produce the half-shell body in a simple one-step process. In particular, at least one of the at least one outer rib element can be formed integrally or monolithically with the half-shell body.

Preferably, at least one outer rib element can be mounted on the half-shell body or on the outer surface. The rigidity of the half-shell body can thereby be adjusted by fitting the respectively required or required outer rib elements. In particular, the production of the half-shell body and the production of the outer rib element can thereby be separated from one another, as a result of which the manufacturing process of the half-shell can be designed more flexibly.

Preferably, at least one outer rib element has an at least partially circular and/or at least partially rectangular or rectangular and/or at least partially triangular or triangular and/or at least partially trapezoidal cross-sectional profile. The cross-sectional contour of the outer rib element at a point or at a point is obtained by the cross-sectional shape of the outer rib element in the cross-sectional plane.

In particular, the outer rib elements have different cross-sectional profiles at different points along the outer rib elements.

Preferably, the at least one stiffening means comprises at least one inner rib element, wherein the at least one inner rib element is arranged in the half-shell body. In particular, the at least one inner rib element may be arranged between an inner surface of the half-shell body and an outer surface of the half-shell body. The at least one inner rib element extends or is distributed at least partially through the half-shell body and is thereby designed to increase the resistance of the half-shell body against elastic deformation due to forces and/or moments, in particular due to forces and/or moments transmitted or caused by the torsion bars.

Preferably, the at least one recess or hole comprises a plurality of recesses or holes arranged between and/or along the splice edges of the inner surface and/or the intermediate faces of the outer surface and/or the inner side (e.g. according to a honeycomb model). The inner intermediate surface is understood to be an imaginary surface which is parallel to the inner and outer surfaces or which has a constant distance from the inner surface and a constant distance from the outer surface, and which is arranged between the inner and outer surfaces. The term joining is understood here to mean mathematically, i.e. covering the inner and/or outer surface and/or the inner intermediate surface by a partial surface or surface piece, in particular a partial surface or surface piece of the same shape, without gaps or overlaps. The intermediate surface of the inner and/or outer surface and/or inner side may be mathematically a euclidean plane, for example by spreading the intermediate surface of the inner and/or outer surface and/or inner side around the body axis. This can be shown mathematically, for example, in an X-Y coordinate system, where the X coordinate corresponds to the distance parallel to the body axis along the intermediate plane of the inner or outer surface or inner side and the Y coordinate corresponds to the distance in the direction of the surround based on the body axis along the intermediate plane of the inner or outer surface or inner side.

In particular, the notches or holes have different cross-sectional profiles at different points along the notches or holes.

Preferably, the at least one recess or hole is not completely surrounded by the half-shell body or opens radially or axially outwards. This makes it possible in particular to simplify further applications, for example in a sheathing with respect to the half-shell body, as will be described below.

Preferably, the front and/or rear side of the half-shell body can each have a surface structure. In particular, the surface structure extends at least partially on the front side and/or the rear side, or the surface structure can have a structure surface at least partially corresponding to a surface of the front side and/or a surface of the rear side. In particular, the front side has a first surface structure and the rear side has a second surface structure, wherein the first surface structure and the second surface structure have a mirror symmetry with respect to one another.

For this purpose, the corresponding structural surface can be mathematically a euclidean plane. This can be shown mathematically, for example, in an X-Y coordinate system, where the X-axis and Y-axis are each perpendicular to the body axis.

Preferably, at least one of the at least one recess or hole is open only towards the outer surface and towards the inner surface and extends completely through the half-shell body. In other words, the at least one recess or hole preferably comprises at least one through hole which opens not only towards the inner surface but also towards the outer surface. In particular, the injection molding of the half-shell body can be achieved simply by providing one or more such through-openings through the half-shell body, since the injection molding material can flow through the through-openings between the inner surface and the outer surface during the injection molding step. The through-hole may be configured to taper toward the inner or outer surface, for example to about 50%, about 30%, about 10%, or less of the diameter of the through-hole on the other side.

Detailed Description

Fig. 1 shows a perspective view of a half-shell body 1. In particular, the half-shell body 1 is designed in one piece here. Furthermore, the half-shell body 1 is of hollow-cylindrical design, wherein the half-shell body 1 corresponds approximately to a hollow cylinder, which is divided in half along its axis. The half-shell body 1 is not limited to this half-divided construction, however, but can correspond to any division of the hollow cylinder along its axis. The half-shell body 1 can also be designed in other geometric configurations, for example as a cuboid with a cylindrical recess for partially accommodating the torsion bar. The axis corresponds in particular to the body axis a of the half-shell body 1.

The half-shell body 1 has an inner surface 3 and an outer surface 2. In particular, the inner surface 3 is here a cylindrical surface of the half-shell body 1 facing the body axis a, which surface at least partially surrounds the body axis a. In particular, the outer surface 2 is here a cylindrical surface of the half-shell body 1 facing away from the body axis a, which surface at least partially surrounds the body axis a. The half-shell body 1 also has an end side 5 and a rear side (not shown for clarity), wherein the end side 5 and the rear side are arranged opposite one another on the half-shell body 1. The end side 5 and the rear side are in particular parallel to each other and the normal vector of the end side 5 is in particular parallel to the body axis a.

The half-shell body 1 comprises nine recesses or holes 4 in the half-shell body 1, wherein the recesses or holes 4 are preferably substantially parallel to the body axis 4. Here, nine recesses or holes 4 are configured as through holes through the half-shell body 1, but wherein the half-shell body 1 is not limited to such a configuration. In particular, one or more recesses or holes 4 may not extend completely through the half-shell body 1, wherein in particular along one or more of its recesses or holes 4 there are one or more partition walls perpendicular to the body axis which separate or close one or more recesses or holes 4 from one another outwards. In particular, nine recesses or holes 4 extend or run from the half-shell body 1 up to the rear side (not shown) of the half-shell body 1. In particular, the recess or hole 4 is arranged between the inner surface 3 of the half-shell body 1 and the outer surface 2 of the half-shell body 1. The recesses or holes 4 have in particular an equal radial diameter, wherein the radial diameter is measured in a radial direction of the body axis a. In particular, the recesses or holes 4 have an equal radial diameter, wherein the radial diameter is measured along the end side 5 of the half-shell body 1. In particular, a uniform distribution of the material, for example the elastomer, can be ensured during the sheathing process, for example injection molding, of the half-shell body 1. The radial diameter of the recess or hole 4 can be determined in accordance with the respective desired stiffness value and/or in accordance with the physical properties of the material used for the sheath. The radial diameter can have a dimension of at least 3mm, preferably at least 5mm, most preferably at least 6mm, and at most 25mm, preferably at most 15mm, most preferably at most 8mm, for example.

However, the half-shell body 1 can also have more or less than eight inner rib elements 7. The inner rib elements 7 extend or extend at least partially through the half-shell body 1 and are therefore designed to increase the resistance of the half-shell body 1 against elastic deformation due to forces and/or moments, in particular due to forces and/or moments transmitted or caused by the torsion bars. In particular, the radial diameter of the inner rib element 7 may be constant in the direction of the circumference with respect to the body axis a in order to achieve a uniform stiffness adjustment. Furthermore, each inner rib element 7 has a minimum thickness, wherein the minimum thickness of the respective inner rib element 7 is measured in a circumferential direction based on the body axis a.

As a further alternative, the at least one circumferential groove 6 of the front side 5 and the at least one circumferential groove 6 of the rear side can be configured to be non-mirror-symmetrical to one another. In particular, at least one circumferential groove 6 on the front side 5 and/or at least one circumferential groove 6 on the rear side are designed such that at least two, preferably all, recesses or holes 4 are connected to one another.

In particular, the at least one circumferential groove 6 is designed such that the half-shell body 1 can be fastened in a production mold for producing the half-shell.

The half-shell body 1A can also be designed in other geometric configurations, for example, as a cuboid with a cylindrical recess for partially accommodating the torsion bar. In particular, this axis corresponds to the body axis a of the half-shell body 1A.

The half-shell body 1A has an inner surface 3A and an outer surface 2A. In particular, the inner surface 3A is here a cylindrical surface of the half-shell body 1A facing the body axis a, which surface at least partially surrounds the body axis a. In particular, the outer surface 2A is here a cylindrical surface of the half-shell body 1A facing away from the body axis a, which surface at least partially surrounds the body axis a.

In particular, the first and second sets of recesses or holes 4A, 4B are arranged alternately in a circumferential direction based on the body axis, respectively. In particular, the recesses 4A, 4B are each spaced apart or separated from one another by an inner rib element 7A. The recesses or holes 4A, 4B and the inner rib element 7A form a reinforcement means 8A.

Fig. 3 shows an exploded view of the torsion bar bearing 10. In particular, the torsion bar bearing 10 is formed here from two half-shells, each of which in particular comprises the sleeve arrangement 11 and the half-shell body 1, respectively.

In particular, the torsion bar bearing can be designed here according to the torsion bar bearing 10 in fig. 3, but is not limited to this embodiment. In particular, the torsion bar bearing 10 here comprises two half-shells, wherein each half-shell has a sleeve device 11. Wherein each sleeve means 11 may enclose at least one half-shell body, which may have any combination of the features described herein. Preferably, the sleeve devices 11 are constructed identically.
