FRICTION-CONTROLLED SUSPENSION FOR WAGON BOGIES

British Railways has 200 cars equipped with friction-controlled trucks with unit brake beams. The integral friction-controlled suspension system for car trucks is designed to provide maximum shock cushioning at high speeds. The ends of the bolsters are supported on nests of coil springs. Sandwiched between the guide faces of the bolster and the guide surfaces of the frames are spring-loaded friction shoes. The controlled friction damping permits use of long-travel low-rate coil springs which give maximum cushioning for all loading conditions. The side frames can be supplied with either the hanger type suspension brake beams, or pockets can be cast in the frames to accommodate the unit type brake beam. The bogie frames can be arranged to accommodate roller bearing axleboxes and either integral or separate plain bearing boxes.
