摘要

The rolling bearings (10, 11, 12, 13) are housed in bearing covers (6, 7) made from single or multi-layered pressed sheet metal parts formed as fine deep drawn parts and connected to the gear housing. The sheet metal parts have sleeve-like bushes (16) and stud-like tops (17) which form directly external and internal track faces (18 , 19) for the needle or rolling bearings (12, 13) which interact with the gear shafts (4, 5). A pressed sheet metal part can be formed as a fine drawn part provided with several deep-drawn tops (24) spaced circumferentially on the input shaft to serve as cylinders for operating pistons for operating the release bearing of a friction disc clutch.
