Abstract
A hinge assembly particularly for mounting the door of a motor vehicle having a first and a second hinge wing with first and second hinge eyes, respectively, thereon, a hinge pin operatively interposed between said first and second hinge eyes and a knurled portion interposed between the hinge pin and one of the first and second hinge eyes to effect nonrotative relative engagement therebetween. A bushing of maintenance-free bearing material is interposed between the hinge pin and the other of the first and second hinge eyes and a liner made of high strength material is inserted in the bushing between the hinge pin and the bushing. The knurled section may extend over the hinge pin at least one and one-half times the length required for securely fixing the hinge pin.
