ABSTRACT:
A constant-velocity fixed joint includes an outer joint part with ball raceways and an inner joint part with ball raceways which are separated by webs. A cage, which is disposed between the outer joint part and the inner joint part, has windows for holding balls. The inner joint part can be inserted into the cage only when at least one of its webs engages in a window in the cage. As a result of certain ratios of the raceway angle to the web angle, a high resistance to fracturing at large deflection angles is achieved and a weakening at the functional faces of the inner joint part is avoided. The large angle of wrap around the balls at the ends of the raceways is advantageous for the load bearing capacity of the raceways. Due to its simple form, the cage can be manufactured with a small thickness.
