Truck mounted brake system

摘要

A truck mounted brake system comprising a brake cylinder mounted on a truck bolster, having a cylinder rod extending through the bolster, wherein a series of elongated slots are provided in the second sidewall and the intermediate webs of the bolster to facilitate access to mounting bolts for the brake cylinder. The slots are dimensioned to avoid unnecessary weakening of the bolster. In the preferred embodiment, the brake cylinder is positioned so that the pivot point at which the cylinder rod joins the brake lever is substantially coaxial with the brake cylinder bushing when the cylinder rod is in its extended, loaded position. Interior and exterior surfaces of the bolster sidewall which the brake cylinder and its associated fasteners engage are preferably substantially planar to avoid loosening of the fasteners over time due to surface irregularities.
