Integrated EBS rear axle braking device

The invention provides an integrated EBS rear axle braking device. The integrated EBS rear axle braking device comprises a valve body assembly, an upper cover (6) assembly, solenoid valve assemblies and a controller cover (20) assembly. Each of the solenoid valve assemblies is internally provided with an air inlet armature assembly (15), an air exhaust armature assembly (16) and a multi-voltage armature assembly (17) from top to bottom in sequence, and the three armature assemblies are integrated into one same solenoid valve assembly. The integrated EBS rear axle braking device utilizes built-in pressure sensors of a rear axle brake module device to monitor the brake chamber pressure in real time, and controls the built-in solenoid valve assemblies through an ECU to increase, hold and depressurize the brake chamber pressure, so that smooth braking of a vehicle is ensured, and the safety of the vehicle and a driver can be guaranteed to the greatest extent. 本发明提供了种集成式EBS后桥制动装置，包括阀体组件、上盖（6）组件、电磁阀组件及控制器盖（20）组件，电磁
