Abstract

A constant velocity universal joint of the tripod type having an outer joint part provided with three circumferentially distributed, axially extending longitudinal recesses with circumferentially distributed opposed running faces, an inner joint part provided with three circumferentially distributed radial journals engaging the longitudinal recesses, with the journals being provided with roller members which are held substantially isogonally in the longitudinal recesses and which are held relative to the journals so as to be radially displaceable and angularly movable, with each roller member being rotatably supported on a roller carrier and with the journals, at their ends, each having pivot heads which are firmly connected thereto and which engage a radial cylindrical inner recess of a roller carrier so as to be radially movable and angularly movable at right angles thereto around two axes.
