Problems solved by technology

Such locking does effectively protect the elastomer against axial dislodgement from the housing, but this solution entails high costs
Because the locking grooves in the housing have to be cost-intensively remachined to obtain vertical locking surfaces

Embodiment Construction

[0026] exist figure 1 A cross-section of a first embodiment of a cardan shaft bearing 10 according to the invention for supporting a cardan shaft, not shown, is shown in FIG.

[0027] The cardan shaft bearing 10 has a bearing seat 12 with a receiving bore 14 into which a rolling bearing 16 is inserted. An elastic body 20 is arranged between the rolling bearing 16 and the bearing housing 12 .

[0028] Such as figure 1 As shown, the elastomer body 20 has an approximately U-shaped cross-section and has a radially inner leg 22 and a radially outer leg 24 connected to each other by an approximately curved base 26 . The radially inner leg 22 now bears against the rolling bearing 16 . In particular, the radially inner leg 22 forms a receiving opening for the rolling bearing 16 . In order to increase the surface contact, an inner bushing 28 is inserted, preferably vulcanized, into the radially inner leg 22 . The inner sleeve 28 can now be connected to the elastomer body 20 in a f...

Abstract

The present invention relates to a cardan shaft bearing (10) comprising a bearing seat (12) with an accommodating hole (14) and an elastomer (16), wherein the elastomer (16) is arranged in the accommodating hole (14) and is fixed on the bearing seat (12) by a securing ring (42). The retaining ring (42) is designed such that it rests exclusively on the elastomer (16).

Description

technical field [0001] The present invention relates to universal joint shaft bearings. Background technique [0002] The universal joint shaft bearing is used to support the universal joint shaft of the motor vehicle to damp the vibrations acting on the universal joint shaft during driving operation. [0003] A universal joint shaft bearing is known from DE 43 20 642 C1, which has a rolling bearing and a bearing seat surrounding the rolling bearing, wherein an elastomer is arranged between the rolling bearing and the bearing seat. In order to prevent locking of the elastomeric body axially out of the bearing seat, the elastomeric body has a collar portion at the free end which abuts against the bearing seat. However, such a solution only protects the elastomer to a limited extent against axial dislodgement. Especially in the case of high axial forces there is the risk that the elastomer will come out of the bearing seat. [0004] In order to avoid this disadvantage, it i...
