Abstract

A tripod joints includes a joint outer part and a joint inner part. The joint inner part has a tripod star with ball pins, which transmits a drive torque from the joint inner part to the joint outer part via a pressure element and via rolling bodies which are arranged between the joint outer part and a running surface of the pressure element. The running surface of the pressure element is curved in the rolling direction of the rolling bodies. The force may be distributed more uniformly between the rolling bodies when large drive torques are intended to be transmitted. The tripod joint may be suitable for the displaceable and pivotable driving connection of two shaft ends, e.g., in conjunction with drive trains or half shafts of motor vehicles.
