A train control system comprising a vital brake interface unit that is disposed between the train control processors and the braking system. The brake interface unit ensures that any failure in the control processors or the interface itself is detectable and, when detected, causes the system to fail safely (i.e., the train's brakes are applied). By virtue of the use of redundant circuitry paths, the vital braking interface unit enables real-time verification of system circuitry without actually applying the train's brakes.

A small vehicle has a frame assembly that is supported by rear wheels. An engine is supported by the frame assembly. The rear wheels are driven by the engine through a shaft drive arrangement.

Provided is a compact brake cylinder device capable of increasing the brake force output from a brake output unit that moves along with a rod, without requiring the device to be made larger. A piston (24) sections off a pressure chamber (43) within a main cylinder (20a), surrounds the axial periphery of a rod (22), and moves in a direct line parallel with the direction of motion of the rod (22). With the supply of a pressure fluid to the pressure chamber (43) the piston (24) moves outward relative to the main cylinder (20a) in opposition to the biasing force of a rod-biasing spring (23). An oscillating member (46) of a force-multiplying mechanism (25) is biased by the piston (24) moving in the outward direction, oscillates, and biases the rod (22), causing the rod (22) to move in the forward direction. In this way, the force-multiplying mechanism (25) multiplies the drive force from the piston (24) so as to act on the rod (22). The brake output unit (21) moves in the forward direction along with the rod (22) and outputs brake force.

In a vehicle caliper brake device, a brake pad 7 supported by a holder 8 applies a frictional force to a braking surface 6 as a diaphragm actuator 60 is driven. The holder 8 is supported by a caliper main body 10 to be capable of displacing in a displacement direction of the brake pad 7. The diaphragm actuator 60 includes a piston 65 that is driven by a diaphragm 76 to push the holder 8. The piston 65 is fixed to the holder 8 using a plurality of screws 66, and therefore the piston 65 applies a pressing force to the brake pad 7 uniformly without the need for guidance by a guide.

A brake lining for a railroad car brake includes friction members which are pressed onto the sliding surface of a brake disc, and a back plate which is attached to a brake caliper in order to support the friction members. The friction members are dividedly arranged in a radial direction and in a circumferential direction of the brake disc. A disc spring is disposed between each respective friction member and the back plate. An outer peripheral surface of the friction members facing the back plate is formed in a convex curved shape in an area outside the elastic member. When a light pressing force is applied, a pressing force is transmitted from the back plate to the friction members via the disc springs. When a heavy pressing force is applied, the back plate and a rounded surface portion make contact, thereby directly transmitting a pressing force to the friction members.
