ABSTRACT:
A linkage is disclosed which is especially adapted for use in articulated rail vehicles to ensure proper transmission of handbrake actuating force from car section to car section regardless of relative movement therebetween. Parallel bar linkages extending between car sections adjust the position of a fulcrum point to prevent changes in the location of vital linkage points, thereby avoiding unwanted brake application or release as the car sections undergo relative movement.
