Technical Field
The present invention relates to a wheel for a vehicle according to the preamble of
Background
Various requirements are placed on the wheels of vehicles, in particular of passenger cars. In addition to sufficient strength and low weight, the wheel should also contribute to a good air resistance coefficient of the vehicle and have a pleasing visual appearance. This also includes the following facts: the visible outer region of the wheel is only slightly contaminated by wear of the wheel brakes arranged on the inner side of the wheel (i.e. the side facing the vehicle). In order to ensure the latter in particular, it is known to cover the gaps between all the spokes of the wheel with respect to the brake disc of the wheel brake rotating together with the wheel by means of one single disc-shaped cover element arranged on the inside of the wheel. In addition, covering elements are also known which cover the spoke spaces one by one.
Typically, such cover elements are glued or securely bolted to the wheel to ensure a secure attachment to the wheel of the vehicle. However, it is difficult to replace or remove the covering element, for example in the case of damage or a change in design.
In this case, a conflict of goals arises between a stable and loss-proof connection of the cover element to the wheel and a simple removal of the cover element.
DE102011107064 a1, for example, shows a two-part cover element which comprises an insert and a snap ring or snap element, which are designed to be snapped into one another. The snap connection elements achieve a fixed snap connection when the snap ring and the insert are pressed into each other.
US 20110107666 a1 also discloses a two-piece element for placement in the spoke interspace.
Disclosure of Invention
The object of the invention is to provide a wheel of a vehicle having a cover element which is connected to the wheel in a loss-proof manner and which ensures simple mounting and dismounting.
This object is achieved by a wheel for a vehicle having the features of
A wheel for a vehicle, in particular a passenger car, is proposed, which comprises a rim, a hub section or a flange region (also referred to as a wheel flange), and at least two spokes connecting the hub section or the flange region to the rim. The at least two spokes adjacent to each other form an intermediate space, the so-called spoke intermediate space, which is at least partially covered by the covering element. The spoke interspace is preferably substantially triangular or in the form of a circular segment. In order to optimize the aerodynamic properties of the wheel, in particular a part of the web intermediate space is covered by a cover element which is spaced as little as possible from the rim of the wheel.
Furthermore, it is preferred that the at least one web intermediate space which is at least partially covered by the cover element extends conically or funnel-shaped from the outside of the wheel in the direction of the inside of the wheel. In other words, the spoke space preferably narrows or diminishes toward the inside of the wheel.
In the sense of the invention, the wheel inner side or the wheel outer side relates to the position of the wheel in the mounted state in the vehicle. In this case, one side of the wheel, i.e. the inner side of the wheel, faces the vehicle, while the other side of the wheel, i.e. the outer side of the wheel, faces away from the vehicle and is visible on the outside. Usually, components of the brake disk or wheel suspension are flanged or connected to the inside of the wheel, in particular to the hub section or wheel flange.
The cover element is mounted on the wheel from the outside or outside of the wheel, i.e. from the outside in the mounted state of the wheel, and is arranged on the outside of the wheel. The cover element is thus connected to the outside of the wheel or mounted externally to the wheel.
Furthermore, it is provided that the cover element is held in the installed position by a fastening device. The fastening device is arranged here on the inside of the wheel, i.e. on the wheel flange. The fixing device is thus attached to the inside of the wheel or mounted internally to the wheel.
In this case, the fastening device is particularly preferably arranged in a planar manner on the wheel flange. The wheel flange can, for example, form the interior of the hub section and is further preferably planar or planar with a planar surface of circular shape. The fixing device can then rest flat on such a surface, which is for example planar.
Furthermore, the plurality of cover elements is preferably held on the wheel outer part in the mounted position by means of a fastening device.
Preferably, the one-piece fastening device forms a fastening device for a plurality of cover elements, each of which at least partially covers a spoke interspace.
Such a fastening device for the covering element is particularly advantageous, since a simple mounting and detachable fastening of the covering element can thereby be achieved, while at the same time a high protection against loss is ensured. The cover element according to the invention ensures simple disassembly if the cover element needs to be replaced or removed for all conceivable reasons, such as damage to the cover element or no longer requiring the cover element at all. By means of the fixing means, the covering element can be connected to the wheel directly and therefore no modifications or special wheel designs have to be considered.
Furthermore, the fastening device itself is preferably connected to the wheel flange.
The connection can be made, for example, in a form-fitting manner, for example, by inserting the fastening device into an existing threaded bore of the wheel flange. Alternatively or additionally, the fastening device can also be connected to the wheel flange by a force fit or a material fit.
In addition to the form-locking, it is therefore particularly preferably provided that the fastening device is held by the installation of a component connected to the wheel flange. The fastening device can be held or clamped between the wheel flange and the component connected to the wheel flange, for example.
The form-fit connection in this case provides a pre-positioning during assembly, while the actual connection of the component connected to the wheel flange provides a fixing of the fixing device.
Furthermore, it is preferably provided that the fastening device comprises at least one wing-like element which at least partially covers the at least one spoke interspace from the inside of the wheel. In this case, the wing-like element projects particularly preferably from the inside of the wheel into the spoke interspace, so that the cover element can be fastened to the wing-like element from the outside of the wheel. The fastening device can be designed, for example, as a star, a circular or annular element resting flat or planar on the wheel flange, while at least one (preferably several) wing-like element(s) projects into the spoke interspace.
Particularly preferably, the covering element is connected to the wing-shaped element in a form-fitting and/or force-fitting and/or material-fitting manner. For example, the wing-shaped element and the covering element can lie on top of one another or abut one another and form a form-fit connection there. Alternatively or additionally, the cover element can be bolted and connected by means of a clip connection with the wing-shaped element.
Furthermore, in order to ensure that the cover element is held as firmly as possible in or on the web intermediate space, the fastening device preferably makes direct contact with the hub section or with the flange region or the wheel flange of the wheel on the inside of the wheel. In this case, for example, the fastening device itself can be held on the hub section or the flange. As already mentioned, this can be achieved on the one hand by a positive or non-positive or cohesive connection of the inner cover element to the wheel flange, but on the other hand the fastening device can also be held or clamped in a surface-like manner between the wheel flange and the component connected to the wheel flange. Such a component connected to the wheel flange can be, for example, a brake disk or a component of a wheel suspension, which is usually connected to the hub section or to the wheel flange of the wheel by at least one screw connection. Thus, for example, the fastening device can be clamped or held in a surface-mounted manner between a component connected to the wheel flange (e.g. a brake disk) and the wheel flange itself.
In a further preferred embodiment of the invention, it is provided that the fastening device or the at least one wing-shaped element is held on the inner side of the wheel and extends through the spoke interspace to the outer side of the wheel. The region of the wing-like element which extends outside the wheel is preferably held or fixed on the wheel web or on the rim of the wheel.
In a further advantageous embodiment of the invention, it is provided that the cover element is connected in a form-fitting manner to at least one spoke and/or to the rim. For example, the covering element or one of them can be hooked onto the spoke edge by means of a hook connection. A secure fit of the covering element can thereby be ensured.
Furthermore, in this case, the covering element can hook or snap into the edge of the rim undercut or into the undercut itself. Such undercuts can be provided, for example, on the rim of the wheel and extend over the entire circumference of the wheel or rim. The wing-like elements of the fastening device can also be held on the wheel disk or wheel rim or connected in a form-fitting manner thereto.
For any additional connection of the covering element, in particular for a hooked connection, the covering element may have means or geometries which allow such a hooked or clipped connection.
The covering element itself is preferably at least partially made of plastic. For example, the cover element can be made of a plastic-metal-layer composite, in which the metal layer is arranged in the wheel outer direction and the plastic layer is arranged in the wheel inner direction or vehicle direction in the installed state of the cover element.
Furthermore, the cover element may be at least partially made of a flexible material. For example, in the above-described embodiments of the fixing means, which extend through the spoke interspace to the outside of the wheel, at least the wing-shaped element of the fixing means can be made of a flexible plastic material. This allows the wing-like element to be simply fed through or across the spoke intermediate space to the outside of the wheel.
Furthermore, a method for mounting a wheel of a vehicle is proposed, which wheel is constructed according to any one of
These and other features are indicated in the claims and from the description and the drawings, and each feature may be implemented alone or in a plurality of sub-combinations in one embodiment of the invention and form an advantageous and inherently protectable embodiment, for which protection is claimed here.
