<p>A constant velocity ratio universal joint of the tripod type, comprising an inner joint member (10) with three outwardly extending arms carrying rollers (21) engaging in guide grooves (20) in an outer joint member (11), the rollers being constrained to roll along the guide grooves without tilting therein and being able to rotate about, slide lengthwise of, and tilt relative to the arms of the inner joint member. Each arm (14) has a part-spherical surface (15) on which is received an inner roller element (22) so as to be able to tilt on the arm, the inner roller element (22) having a cylindrical external surface (24) on which roller (21) is able to rotate and slide.</p> |
