Document Type and Number:
WIPO Patent Application WO/2018/038256
Kind Code:
A1
Abstract:
A pneumatic brake system causes brakes to operate by supplying air to a brake mechanism provided on each wheel of a vehicle, and releases the brakes by discharging air from the brake mechanism. A safety air supply part and a shuttle valve are provided to each brake mechanism. The safety air supply part is operated by a safety brake control device in emergencies, and supplies air to the brake mechanism. The shuttle valve is connected to the safety air supply part and to a brake air supply circuit for supplying air to the brake mechanism by way of a route that is different from the safety air supply part, and the shuttle valve allows the flow of air to the brake mechanism only from the part having the higher pressure, among the safety air supply part and the brake air supply circuit.
