Abstract:
A bushing assembly includes a tube with an outer bearing surface, a metal part with an annular flange defining an opening and a plastic bushing with a bushing hub with an inner annular bushing contact surface and an axially extending metal part engagement surface. A friction torque setting connection is formed between the annular flange and the bushing hub and defines a rotational and axial connection between the annular flange and the bushing hub. The connection is configured to vary a radial force applied between the annular flange and the bushing hub with a deformation of bushing plastic material. This is to vary friction between the bushing contact surface and the tube outer bearing surface upon applying a torque to the plastic bushing, causing rotation and axial movement of the plastic bushing relative to the metal part, and causing the deformation of plastic material of the bushing hub.
