Abstract
A constant velocity universal joint of the tripod type having an outer joint part with three axis-parallel recesses each forming circumferentially opposed pairs of running grooves. An inner joint part with three circumferentially distributed radial arms with spherical heads each engage one of the recesses. The joint also has guiding pieces for rolling contact members. The guiding pieces each comprise a radially extending cylindrical inner aperture radially movably and articulatably slidingly engaged by one of the spherical heads and longitudinally directed guiding grooves holding rolling contact members rolling in the running grooves. The guiding grooves are each provided with end stops at both ends and with a free rolling path available to the rolling contact members in the guiding grooves between the end stops.
