Tripod joint for motor vehicles has journals with hammer-shaped heads completed by circular plate segments forming circular running track for bearing needles

摘要

The joint has a central/ring part (32) with three integral journals (31). Each journal has two opposite end faces shaped like spherical segments with a common center on the journal axis, and opposite slide surfaces. Two plate segments (42,43) engages with their inner surfaces on the slide surfaces. The segments have outer cylindrical jacket-shaped running surfaces. Bearing bodies (44) formed as cylindrical bearing needles run in cylindrical running surfaces of rollers (41), and on peripheral surfaces formed by the journal end faces and outer segment surfaces.
