ABSTRACT:
The invention relates to a constant velocity fixed joint having an outer part 1 carrying a supporting element 9. An inner part 11 has a hollow spherical control face 17. A cage 18 is guided on the inner part 11 and holds balls 21 which, transmit torque between the inner part 11 and the outer part 1 by engaging outer running grooves 5 in the outer part 1 and inner running grooves 14 in the inner part 11. A control element 22 has a spherical contact face 23 which supports the inner part 11 in that the latter is supported on the contact face 23 by means of the control face 17. Furthermore, the control element 22 is supported by a holding face 25 against a supporting face 10 of the supporting element 9 for the purpose of centering the inner part 11 along the longitudinal axis 2 of the outer part on the joint articulation center 0. To reduce the sliding friction between the control face 17 and the contact face 23, the cavity 26 is filled with lubricant and supplies the faces sliding on one another with lubricant through apertures 28 which end in lubricating grooves 27.
