Abstract
The invention relates to a drive assembly comprising a constant velocity fixed joint A and rolling contact member guide B. The constant velocity fixed joint A is designed in such a way that its outer part 1 and its inner part 3, for the purpose of guiding the balls 5, are provided with two outer running grooves 14, 15 alternately extending from two opposed open ends 10, 11 in distributed planes in an undercut-free way and, opposite thereto, two inner running grooves 17, 18. The cage arranged between the inner part 3 and the outer part 1 for the purpose of guiding the balls 5 is guided by a hollow-spherical portion of its inner face 21 on the spherical outer face 19 of the inner part 3. The rolling contact member guide B connected to the inner part 3 comprises a plunging journal 33 which enters a bore 39 in the plunging sleeve 38. The plunging journal 33 and the plunging sleeve 38 comprise opposed inner grooves 37 and outer grooves 40 respectively in which guiding balls 41 are adjustably held by guiding cage 42 along with setting axis 35. By combining a constant velocity fixed joint A comprising running grooves extending in opposite directions with rolling contact member guide B, it…
