Abstract

An arrangement with a joint and a gearwheel body for a transmission is provided in which the joint is a constant velocity joint arranged at least partially in an interior space enclosed by the gearwheel body. The constant velocity joint has inner and outer hub tracks and a bearing cage arranged to maintain an essentially constant control angle between tangential ball contact points with the inner and outer tracks while the bearing cage holds the balls in a plane.

Claims (24)

1. An arrangement with as joint and a gearwheel for a transmission, comprising:
