Tripod joint
摘要:
Tripod joints have a joint outer part and a joint inner part which are in driving connection to each other with cylindrical rolling bodies being connected in between and axial displacement and pivotability being ensured. In this case, the rolling bodies extend in rectilinear, guiding running paths of the joint outer part. The rolling bodies are mounted in a manner such that they may be displaced longitudinally via the cages but to a restricted extend radially with respect to the pressure element. The radial extent of the running paths or mating surfaces is greater than the longitudinal extent of the rolling bodies. This enables the rolling bodies to move on a path in the shape of a circular arc. The arrangement provides an improved, mechanical transmission function of the tripod joint and reduced wear as a result. The tripod joint is suitable for the displaceable and pivotable driving connection of two shaft ends, e.g., in conjunction with drive trains or side shafts of motor vehicles.
