Kreuzgelenk mit verbesserter Schmierung

摘要

A universal joint (10) has a ball retainer (32) having a retainer body (30) made of a structurally rigid material and a relatively soft elastomeric seal bonded to the body at an axial end in a recess so as to wipe lubricant back on the ball (20) that is retained by the body. Cavity plates (62) in a housing of the universal joint partially close off lubricant reservoir (66) recesses to retain lubricant in the reservoirs and act as wear plates that stabilize the centering plate orbiting in the recess. Seals (174) can be provided between the retainer and the ball socket, between the centering plate and the wear plates and between the wear plates and the cavity plates. Passageways connect the center cavity (29) of the housing with the ball sockets through an orifice.
