  • Patent number: 7103975
    Abstract: An intermediate bearing for a driveline of a commercial vehicle has a housing (7) with a stirrup-shaped cross-section. The housing (7) has a fixing face (12) formed of two straight portions (8, 9) and a first arched portion (10). A bearing member (15) is arranged between the portions (8, 9, 10). The bearing member (15) is rubber and is connected to the fixing face (12) by vulcanization. A locking element (23) bridges the space between the two straight portions (8, 9). The locking member (23) is attached to the bearing member (15). The bearing member (15) encloses a supporting ring (16) which serves to receive a rolling contact bearing. The locking element (23) is adjustable for the purpose of setting a pre-tension of the bearing member (15) towards the longitudinal axis (18) of the bore (17) of the supporting ring (16). The locking element (23) can be connected to the housing (7) after the required pre-tension has been set.

  • Patent number: 6350201
    Abstract: The invention relates to a universal joint having a first joint yoke (1) and a second joint yoke (8) as well as a cross member (23) for connecting said yokes. In the region of its two second yoke arms (11), the second joint yoke (8) is separated along a line extending through the second bearing bores, so that per yoke arm (11), there are obtained two yoke arm portions (15) continuing to be connected to the base portion (9), and a separate bridge portion (16). Separation takes place in the form of fracture separation, for which purpose regions in the second bearing bores are heat-treated by laser along a line; thereafter, a force applied to and concentrating on said regions leads to fracture faces which correspond to brittle fracture faces, so that after the separating operation, joining can easily take place without the bearing bores subsequently having to be re-machined. In this way, assembly is simplified.
