Abstract:
1. A tripod joint for transmitting a driving torque between two driving elements of a drive train, comprising: a pressure element including parallel running surfaces; a joint inner part including a tripod star having pins with ball bodies, the ball bodies mounted pivotably with respect to the pressure element about an axis transverse with respect to a plane defined by a longitudinal axis of the joint inner part and a longitudinal axis of the pin; a joint outer part holding the joint inner part and including mating surfaces; cages, each cage mounted longitudinally displaceably with respect to the pressure element, the cages including shoulders configured to restrict movement of the cage with respect to the pressure element in a radial direction, the shoulders one of engaging around and enclosing the pressure element; and essentially cylindrical rolling bodies, having longitudinal axes positionally fixed with respect to the cages, arranged between the parallel running surfaces of the pressure element and the mating surfaces of the joint outer part, the rolling bodies arranged in the cages longitudinally; wherein a radial extent of the mating surfaces, at least in subregions, is greater than one of a longitudinal extent of the rolling bodies and a radial extent of the cage configured to guide the rolling bearings, the cages arranged to move along curved paths with the rolling bodies.
