Abstract
A yoke-type pivot joint comprises a first member including a pair of parallel portions releasably fixed relative to each other and provided with holes which are axially aligned with each other and with a hole provided in a second member located between the parallel portions. A bushing is press fit into the hole of the second member and a pivot pin is received in the bushing and in the holes of the parallel portions. Received on the pin at opposite ends of the bushing are first and second pairs of opposed Belleville springs. One end of the pin is fixed to one of the parallel portions of the first member and a cap is fixed to the other parallel portion and is received on the other end of the pin. A cap screw extends through the cap into the pin and is operative for drawing the end of the pin against the cap and thereby effecting a predetermined compression of the springs at the ends of the bushing.
