ABSTRACT:
A Hookes joint comprising a cross member (10) and yokes (12) has respective lubricant bores (22, 24 and 26, 28) formed in journals (14, 16 and 18, 20) of the cross member. Leaf springs (48, 50) are located within the respective throughbores to project outwardly of the ends thereof into nonrotatable engagement with bearing cups (30, 32), each nonrotatably secured within ends of a yoke. Each bearing cup permits rotation of an associated cross member journal therein whereby, upon relative rotation between the cross member and a yoke, a respective leaf spring (48 or 50) rotates within the throughbore (22, 24 or 26, 28) causing a wiping or sweeping action of the spring within the lubricant in the bore thereby ensuring that the bore does not become constricted. Uniform distribution of lubricant to the bearing cups is thereby assured.
