Tripod constant velocity universal joint

摘要

A tripod constant velocity universal joint comprising a housing (5) having longitudinal grooves (4) arranged in spaced relationship on a periphery thereof, and a tripod spider (2) comprising symmetrically arranged, rotationally symmetrical ball-headed trunnions (3) on which an inner ring (6) comprised of two semi-shells or made as a split ring is retained in a form-fitted manner for angular displacement, said inner ring (6) being radially surrounded by a guide element (7) with rolling elements (10) arranged between the guide element (7) and an outer ring (11) which is guided outwardly for sliding displacement in the longitudinal grooves (4), characterized in that a length of the rolling elements (10) is larger than a width of the outer ring (11), the guide element (7) as seen in longitudinal cross-section is U-shaped and comprises end flanges (8, 9) which extend radially outwards so as to project beyond an inner diameter of the outer ring 11.
