GROUND ENGAGING BRAKE FOR HEAVY VEHICLES

摘要

A brake for preventing heavy vehicles from sliding downhill in the backward direction on a slippery surface is disclosed. The brake comprises at least one ground-engaging member pivotally mounted on the frame of the vehicle and adapted to engage the ground, and means for pivoting such a ground-engaging member into engagement with the slippery surface, whereby, upon backward movement of the vehicle, the ground-engaging member will be positively driven into the ground by the weight of the vehicle to stop the backward movement of the vehicle. The outer ground-engaging end of the member is wedgeshape and defined a flat and surface which is upwardly inclined towards the rear of the vehicle when the ground-engaging member is in operative position.
