ABSTRACT:
A constant velocity universal joint has an outer part (1) with outer tracks (3), and an inner part (6) with inner tracks (10) which, together, each receive one of a plurality of balls (13). The ball is guided by a cage (14). The cage is guided on a guiding face (9) of the inner part (6) by a spherical guiding face (16). The outer part (1) is closed towards one side by a first attaching part (5). The other side is closed by a sealing boot (20) which is secured to the outer part (1) on the one hand and to a second attaching element (12) on the other hand. The second attaching element (12) is connected to the inner part (6) so as to be rotationally fixed. The inner part (6) is held and centered relative to the outer part (1) by the balls (13) and the cage (14) on the one hand and by a control element (18) arranged between the outer part (1) and the inner part (6) on the other hand. To permit lubricant to be stored specifically in the region of the two guiding faces 9, 16 which are in contact with one another, there is provided a sealing cap (21) which at least partially covers the outer cage face and a sealing face (13) associated therewith. As this method achieves improved lubrication conditions, it is possible to use simpler lubricants as well, such as those used in rolling contact bearings.
