Technical Field

The present invention relates to vehicles of the generally motorized type and more precisely to wheel (or suspension) triangles for fitting on some of these vehicles.

Background

As known to those skilled in the art, some vehicles, generally of the motorized type, comprise: a chassis to which a front axle including right and left front wheels each equipped with a hub is coupled; and the two wheel triangular pieces are respectively connected with the chassis and the two hubs.

These wheel triangles (also called suspension triangles or suspension arms) comprise a main part, usually with three ends. The first end portion is adapted to be coupled to a hub of a front wheel of a vehicle. The second end is equipped with a first articulation for coupling with the vehicle chassis. The third end comprises a fixing rod connected with a second joint, the second joint is rotatably accommodated in the concave part of a connecting piece, and the connecting piece is fixedly connected with the chassis into a whole.

In some wheel triangles, the fixing rod comprises A stop that prevents the second joint from translating and is added on the third end by welding or screwing, as described in particular in patent document WO-A-2010105340. This means that not only the assembly operation needs to be carried out, but also the stocking, transportation and storage of these fixing bars needs to be managed.

In some other wheel triangles, the fixed rod is an integral part of the main part and a stop that prevents translation of the second joint is added by welding at a non-free end of the fixed rod. The fixing rod has a circular cross section, and the immobilization of the second joint relative to the fixing rod is performed by force fit by means of a press. Furthermore, additional operations must be carried out to weld the stopper.

Disclosure of Invention

It is therefore an object of the present invention to improve this situation.

The invention provides, inter alia, for this purpose a wheel (or suspension) triangle comprising a main part comprising:

a first end for coupling with a hub of a wheel of a vehicle,

-a second end equipped with a first joint for coupling with a chassis of the vehicle, an

-a third end comprising a fixing rod to which a second joint is coupled, said second joint being rotatably housed in a recess of a coupling for being fixedly integral with said chassis.

The wheel triangle is characterized in that:

-the fixing bar is flat and,

-the second joint comprises a first channel, the transverse cross-section of which has a first shape which is non-circular, an

-the wheel triangle comprises a collar having a transverse cross-section with a second shape enabling the collar to be non-rotatably fitted in the first channel, and the collar is provided with a second channel enabling the collar to be non-rotatably fitted on the fixing rod.

Thus, the collar is not drivable in rotation relative to the flat fixation rod and the second joint is not drivable in rotation relative to the collar and thus the second joint is not drivable in rotation relative to the fixation rod.

The wheel triangle according to the invention may comprise other features which may be adopted individually or in combination, in particular:

-the primary part can be stamped so as to have a peripheral edge which is turned up and extends to the end of the fixing rod so as to define an anti-translation stop for the collar and the second joint;

the fixing bar may comprise an elongated rib defined by stamping, and a transverse cross-section at the elongated rib may have a third shape. In this case, the transverse cross-section of the second channel has a fourth shape corresponding to the third shape;

-the elongated rib may be elongated into the third end;

the fixation rod may comprise a groove defined opposite the elongate rib, in which groove an added reinforcement is partially accommodated, the added reinforcement serving to increase the stiffness of the fixation rod;

the added reinforcement can be made of steel, for example;

the collar may be made of steel, aluminum or plastic, for example;

-the first shape and the second shape may be rectangular.

The invention also provides a vehicle, optionally of the motorized type, comprising: a chassis to which a front axle is coupled, the front axle comprising right and left front wheels each equipped with a hub; and two wheel triangles of the above type respectively coupled to the chassis and to the hub.

Drawings

Other features and advantages of the present invention will become more apparent upon reading the following detailed description and the accompanying drawings, in which:

fig. 1 schematically shows an embodiment of a wheel triangle according to the invention during assembly.

Detailed Description

The invention is particularly aimed at providing a wheel (or suspension) triangle TR intended to be fitted on a vehicle and provided with a knuckle a2 fitted on a fixed rod TF via a ring bush BA.

In the following, as a non-limiting example, the wheel (or suspension) triangle TR is considered for fitting on a vehicle of the motorized type (for example a car). The invention is not limited to this type of land vehicle. The present invention relates to a land vehicle of virtually any type comprising a chassis to which a front axle is coupled, said front axle comprising right and left front wheels each equipped with a hub to which a wheel triangle is to be coupled, said wheel triangle itself being coupled to said chassis.

Fig. 1 schematically shows an exemplary embodiment of a wheel triangle TR according to the invention during assembly.

As shown, the wheel triangle TR according to the present invention, once assembled, comprises at least one main part PP, a ball joint coupling LR, a first joint a1 and a second joint a2, a joint PC, a fixing rod TF and a collar BA.

The main part PP has a substantially triangular shape, hence the name wheel triangle, and therefore comprises a first end E1, a second end E2 and a third end E3. The main part is made of metal (e.g. steel), for example. Furthermore, the main part is preferably made by stamping, for reasons that will be understood below.

The first end E1 is intended to be coupled to the hub of a wheel of a vehicle. The first end comprises for this purpose a ball joint coupling LR, which is added, for example, by means of a screw connection, as shown in a non-limiting manner in fig. 1.

The second end E2 is equipped with a first joint a1 for coupling with the chassis of the vehicle. For example, the first joint a1 may comprise a joint made of (optionally synthetic) rubber or made of a plastic materialA cylinder of the type. Note that the first joint a1 may be integral with the second end E2, either directly or indirectly via fasteners added below the second end E2.

The third end E3 includes a flat fixing rod TF to which a second joint a2 is coupled. It should be understood that the fixing rod TF is an integral part of the main part PP extending from the third end E3.

The second joint a2 is rotatably received in a (for this purpose adapted) recess EA of a coupling piece PC intended to be fixedly integrated with the chassis of the vehicle, for example by means of a screw connection. In addition, the second joint a2 includes a first channel P1 having a non-circular first shape in transverse cross-section (to prevent rotation).

The second joint a2 has a cylindrical shape so as to be able to rotate in a recess EA of the link PC having a cylindrical shape. The second joint can be made of, for example, (optionally synthetic) rubber or of a plastic materialType (b) is used.

The link PC may be made of metal, for example. Thus, the coupling piece may be made of aluminum or steel, for example. The joint part PC may have, for example, the shape of a hollow cylinder with lateral tabs that enable it to be fixed to a portion of said chassis, as shown in a non-limiting way in fig. 1.

The transverse cross-section of the collar BA has a second shape enabling the collar to fit non-rotatably in the first passage P1 of the second joint a 2. In addition, the collar BA is provided with a second passage P2 which enables the collar to be non-rotatably fitted on the fixing rod TF.

The collar BA cannot be rotationally driven with respect to the fixed rod TF because the fixed rod TF is flat and the second joint a2 cannot be rotationally driven with respect to the collar BA, and therefore the second joint a2 cannot be rotationally driven with respect to the fixed rod TF. In addition, it is no longer necessary to prepare a welding operation to fixedly integrate the fixing rod with the main part, and it is no longer necessary to prepare a member for immobilizing the second joint with respect to the fixing rod.

As mentioned above, advantageously, the master part PP is stamped so as to have a peripheral edge RP which is turned up and extends to the (non-free) end ET of the fixing rod TF so as to define an anti-translation stop for the loop BA and the second articulation a 2. Thus, the need to add an anti-translation stop by welding at the end ET is advantageously avoided. The anti-translation stop thus defined by the free ends of the two peripheral edges RP is in fact implemented during the stamping operation of the main part PP.

For example, as shown in non-limiting manner in fig. 1, the fixation rod TF may comprise an elongated rib NL defined by stamping. The elongated ribs NL serve to increase the stiffness of the fixing rod TF and the (anti-rotation) retention of the collar Ba. In this case, the transverse cross-section of the fixing rod TF at the elongated rib NL has a third shape and the transverse cross-section of the second passage P2 of the collar BA has a fourth shape corresponding to the third shape. The third shape and the fourth shape are corresponding (i.e., substantially identical), and the (anti-rotation) retention force of collar BA with respect to fixing rod TF is thus further increased.

It is noted that in order to further strengthen the rigidity of the fixation rod TF, advantageously, the elongated rib NL extends into the third end E3, as shown in a non-limiting manner in fig. 1.

It is also noted that, although not shown in fig. 1, the fixation rod TF may include a groove defined in the opposite side of the elongated rib NL, in which groove an added reinforcement is partially received, the added reinforcement serving to increase the stiffness of the fixation rod TF.

For example, the added reinforcement may be made of steel. Further, the added reinforcement portion may be integrally connected to the fixing rod TF by, for example, welding or adhesion.

It is also noted that the collar BA may be made of steel or aluminum or plastic, for example.

It is also noted that the first and second shapes of the respective transverse cross-sections of the first passage P1 and the loop BA, as shown in a non-limiting manner in fig. 1, may be, for example, rectangular. Other shapes that resist rotation are contemplated.
