To provide a pneumatic brake system capable of enhancing redundancy.SOLUTION: There is provided a pneumatic brake system 10 for supplying air to a brake chamber 50 of a vehicle for actuating a brake, discharging air from the brake chamber 50, and releasing the brake. The pneumatic brake system comprises: security air supply parts 33 for supplying air to the brake chamber 50 and being actuated by a second EBS ECU 15B in emergency; and shuttle valves 34 which are provided between the security air supply part 33 and a brake air supply circuit, and allowing only an air flow in a direction going to the brake chamber 50 from a high pressure side out of the security air supply part 33 and the brake air supply circuit, and the security air supply part 33 and the shuttle valve 34 are provided for every wheel of the vehicle.SELECTED DRAWING: Figure 3

    【課題】冗長性を高めることのできる空気圧ブレーキシステムを提供する。【解決手段】車両のブレーキチャンバー50に対して空気を供給してブレーキを作動させ、当該ブレーキチャンバー50から空気を排出してブレーキを解除する空気圧ブレーキシステム10であって、非常時に第2EBSECU15Bによって作動し、ブレーキチャンバー50に空気を供給する保安用空気供給部33と、保安用空気供給部33と、ブレーキ空気供給回路の間に設けられ、保安用空気供給部33及びブレーキ空気供給回路のうち高圧側からブレーキチャンバー50へ向かう方向のみの空気の流れを許容するシャトル弁34と、を備え、保安用空気供給部33及びシャトル弁34は車両の車輪毎に設けられる。【選択図】図3
