Description

The present invention relates to a stabilizer bearing for a two-lane vehicle, in particular a motor vehicle.

The stabilizer connects in a road vehicle the opposite wheels as a kind of "torsion bar". For this purpose, the generally tubular stabilizer is secured by the stabilizer bearing on the vehicle body. According to the current state of the art, the bearing consists of an elastomer core or elastomer ring, for receiving the stabilizer bar. This core is covered by a rigid support, designed as a retaining bracket, and held on the body. The core is connected as firmly as possible to the stabilizer and the headband to prevent corrosion in the bearing or acoustic problems. The publication DE 10 2010 033 036 A1 shows, for example, a stabilizer bearing with two bearing shells, wherein the elastomeric parts are vulcanized with the bearing shells.

It is an object of the present invention to provide a stabilizer bearing for a two-lane vehicle, which can be easily mounted at low cost production and can be operated permanently.

The object is achieved by the features of the independent claims. The dependent claims have advantageous embodiment of the invention the subject.

Thus, the invention is achieved by a stabilizer bearing for a two-lane vehicle, in particular a motor vehicle. The stabilizer bearing comprises a bearing shell with a U-shaped recess. In this recess, an elastic ring is used to hold the stabilizer. The ring can consist of several ring parts. The ring is especially made of rubber. Furthermore, a closure element is inserted in the recess. The ring with stabilizer is clamped between a bottom of the recess and the closure element. By means of this closure element, it is possible to apply a bias on the ring before the final assembly of the stabilizer bearing on the vehicle. On an outer wall of the closure element and an opposite inner wall of the bearing shell, a closure mechanism is provided. This locking mechanism serves to hold the closure element in the bearing shell. Even before mounting on the vehicle, a self-contained composite of stabilizer bearing and stabilizer can be formed. By the closure element and the locking mechanism thus the stabilizer and the elastic ring are firmly fixed already before mounting on the vehicle in the bearing shell.

Advantageously, it is provided that the closure mechanism is designed as a latching mechanism or clamping mechanism. In the latching mechanism, corresponding projections, for example latching lugs or hooks, are formed on the outer wall of the closure element and the inner wall of the bearing shell, which latch into one another when the closure element is inserted into the bearing shell. When clamping mechanism a corresponding transition or interference fit between the two elements is provided.

Advantageously, it is provided that the closure element sits completely in the recess after assembly. The recess in the bearing shell is therefore chosen so large that they can accommodate the stabilizer including elastic ring and the closure element.

Preferably, the closure element is a one-piece component, in particular, the closure element is made of plastic. Furthermore, it is also preferably provided that the bearing shell is a one-piece component. Also for the bearing shell advantageously plastic is used. Alternatively, metal can also be used for both elements.

The bearing shell advantageously comprises one or more attachment points for fastening, in particular for screwing, the bearing shell on the vehicle. In particular, it is provided that only the bearing shell is connected to the vehicle, in particular screwed. The closure element is not connected directly to the vehicle, but is trapped between the bearing shell and the vehicle.

Advantageously, the bearing shell and the closure element form a common connection surface, which rests on the vehicle in the mounted state. Before mounting on the vehicle, the closure element does not have to be pushed completely into the recess of the bearing shell. Thus, before mounting on the vehicle, the connection surface of the closure element can project slightly beyond the attachment surface of the bearing shell. As soon as the bearing shell is screwed to the vehicle, the closure element pushes completely into the recess, so that the two attachment surfaces are flush and rest against the vehicle. The closure element is further secured against axial displacement by positively fitting into the inner wall of the outer shell.

The invention further includes an arrangement with a just described stabilizer bearing and a corresponding stabilizer in the bearing. The stabilizer is located in particular between two opposite wheel suspensions of a motor vehicle.

In addition, it is preferably provided that at least one ring member is materially connected to the bearing shell or with the closure element. Furthermore, it is preferably provided that at least one ring member is materially connected to the stabilizer. The cohesive connection is made by gluing or vulcanizing. As an alternative to the cohesive connection via bonding or vulcanization of the ring member with the bearing shell or with the closure element is also preferably provided that the bearing shell are made with a ring member and / or the closure member with a ring member in a 2-component injection molding. In this 2-component injection molding process, the bearing shell together with the ring part or the closure element and the ring part are manufactured in one tool. In particular, the tool is chosen so that by appropriate undercuts a positive connection between the bearing shell and the ring member or between the closure member and the ring member is formed.

The invention also comprises a further stabilizer bearing for a two-lane vehicle, in particular a motor vehicle. This further stabilizer bearing comprises a first bearing shell and a second bearing shell, which together form a receiving space. In the receiving space an elastic ring of at least two ring parts is used. The elastic ring in turn serves to receive the stabilizer. The individual ring parts are each arranged in the bearing shells. According to the invention it is provided that at least one ring member is positively connected to a bearing shell, so that the ring member is fixed in both directions perpendicular to the stabilizer in the bearing shell. The positive connection between the ring part and bearing shell is chosen so that the ring member can not fall out of the bearing shell.

This positive connection is made by appropriate undercuts, such. B. small tees or splines or tooth profiles or stepped profiles or rib profiles between the ring member and the bearing shell achieved.

In particular, it is provided to manufacture at least one bearing shell together with the elastic ring part in a 2-component injection molding process. In this case, the bearing shell and then the ring part are manufactured in a process step in a tool first.

The additional stabilizer bearing makes it easy to install units each made of bearing shell and ring part. By the positive connection corresponding disadvantages of the prior art are eliminated: The conventional compounds by vulcanization or bonding between the ring member and bearing shell are aging and susceptible to corrosion. Furthermore, due to the constant movement of the stabilizer, the connection is released, in particular due to the stiffness jump of the boundary layer on the bond. This in turn leads to disadvantages in driving dynamics comfort and acoustics. The positive connection according to the invention avoids these disadvantages as far as possible.

Further, an arrangement comprising at least the further stabilizer bearing and a stabilizer is provided, wherein at least one ring member with the stabilizer cohesively, in particular by vulcanization or bonding, is connected.
