Abstract
A constant velocity ratio universal joint of the tripod type comprising a hollow outer joint member having a rotational axis and three interior guide grooves parallel to its rotational axis and equally circumferentially spaced thereabout, each guide groove having a base portion and opposed side portions; an inner joint member, inside the outer joint member, having a rotational axis and three arms equally spaced about this rotational axis and extending radially into the outer member guide grooves; each arm carrying a roller assembly with an outer roller element having an external surface engaging opposed side portions of a guide groove; an inner roller element mounted on the arm and supporting the outer roller element so that the outer roller element can rotate about, move lengthwise of, and tilt relative to the arm; and a guide element engaging the base portion of the guide groove for sliding movement therealong and also engaging the outer roller element to constrain the outer roller element against tilting relative to the guide groove.
