Abstract
Description
Technical Field
[0001] The present invention relates to a connecting member having a member body provided with a plurality of connecting regions. In the member body, a receiving recess extending in the axial direction is provided in a first connecting region among the plurality of connecting regions. An elastomeric support member is placed in the receiving recess. The elastomeric support member has a support inner member and an elastomeric body surrounding the support inner member. The elastomeric body is surrounded by a wall portion of the member body that defines the boundary of the receiving recess of the first connecting region. Background Art
[0002] Such a connecting member is used, for example, as a connecting rod in vehicle construction, especially as a swing support. A swing support typically includes a large bearing and a small bearing. The large bearing is responsible for path and comfort, and the small bearing is responsible for guidance. The large bearing is locked in the connecting rod, for example, by an additional housing. Alternatively, the large bearing has, for example, an outer member or a plurality of outer member segments and is locked to the connecting rod in a friction fit or form fit manner. The elastomeric body of the large bearing can also be directly connected to the connecting rod by vulcanization, or the bearing can be assembled in the connecting rod by a rubber profile. However, in this case, the bearing is only suitable for small movement paths.
[0003] To lock the large bearing, either additional components are required, or the elastomeric body has to be made relatively large, which, however, is accompanied by few nests in the vulcanization mold. Summary of the Invention
