Rail vehicle dual braking system control - uses system switch on bogie and cam-profiled piston rod to operate valve switches

摘要

The automatic switching arrangement is for a rail vehicle dual braking system. It consisting of a system switch (41) and a pair of valve switches (13, 14) with a hollow cylinder (1). The cylinder has a piston (2) the piston rod (3) of which has cam-shaped formations (4, 5) working in conjunction with the valve switches (13, 14). A spring-loaded switching slider (22) with a contact tappet (20) is fitted above the wheel bogie such that the system switch (41) is in the contact region of the rotary frames (21) or (39) of the wheels. USE/ADVANTAGE - Allows braking for rail vehicles using the UIC track system or the SZD track system.
