ABSTRACT:
A lubricant supply assembly for a universal joint comprises a universal joint, two rotation shafts connected via the universal joint and being capable of being bent relative to one another, ball-and-socket joints secured at the two rotation shafts, and a coupling tube provided at the universal joint for introducing a lubricant from one of the two rotation shafts to the other of the two rotation shafts. The coupling tube is a single tube. The end of the coupling tube is fixed to a ball in one of the ball-and-socket joints while the other end of the coupling tube slidably penetrates a ball in the other of the ball-and-socket joints to protrude from it.
