Abstract

The invention relates to a bearing assembly (1) for radially and axially mounting a shaft part (2) relative to a housing (3). Said bearing assembly comprises two radial antifriction bearings (4, 5) which are disposed on the shaft part (2) at an axial distance from each other as well as two axial antifriction bearings (6, 7) that are arranged on the shaft part (2) at an axial distance from each other. In order improve mounting especially of a bevel pinion, the inventive bearing assembly further comprises an outer bearing ring (9) which is inserted into a housing (3) bore (8), is embodied as a monolithic component, and encompasses the tracks (10, 11, 12, 13) for the two radial antifriction bearings (4, 5) and the two axial antifriction bearings (6, 7).

Description

technical field

[0001] The invention relates to a bearing arrangement for radially and axially supporting a bevel pinion of a vehicle main drive relative to a housing, wherein the bearing arrangement has two diameters arranged on the bevel pinion at an axial distance from each other. A rolling bearing and two axial rolling gears arranged on the bevel pinion with an axial distance from each other. Background technique

[0002] To support the bevel pinion shaft in the vehicle main drive, in particular in the rear axle main drive, tapered roller bearings or angular contact ball bearings are usually used in O-shaped configuration. See JP06323329A for an example in this regard. Such a bearing arrangement is preloaded and provides an advantageous radial and axial fixation of the pinion shaft.

[0003] Another support structure for a bevel pinion shaft is disclosed in JP2003-166627A. The shaft is supported here using two ball bearings and a cylindrical roller bearing. The beari...
