ABSTRACT:
A hinge assembly for an articulated vehicle having front and rear frame portions joined at a pair of vertically aligned hinges. Each hinge includes a similar roller bearing assembly attached to the front frame portion and having a rotatable protruding trunnion. The rear frame portion includes recesses for receiving the trunnions and trunnion caps for retaining the trunnions. The trunnion of each bearing assembly includes a shoulder pin with a first bearing cone placed against the shoulder and a second bearing cone spaced apart from the first cone. A spacer ring received on the pin is biased against the second cone by an end cap secured to the end of the pin. A shim pack between the end cap and the end of the pin limits the amount by which the space between the cones may be to limit and control the pre-load of the bearing assembly.
