摘要： A parking brake for a rail car vehicle including an electric motor driving a hydraulic pump fluidly connected to and controlling a bidirectional hydraulic actuator coupleable to the rail car's wheel brakes. An electric controller is connected to the pump and controls activation/deactivation of the pump with the controller including various switches. Also included is a coupler for coupling the actuator to one of a brake beam or an actuator of the parking brake.

摘要： The present disclosure relates to a pump system for parking brakes for a rail vehicle. The pump system includes at least one actuator, at least one pump and a reservoir as a fluid source. Also included is a manifold in fluid communication with the reservoir and the actuator. Further included are a plurality of valves and fluid paths internal to the manifold to allow fluid flow among the at least one pump and the reservoir.

摘要： An actuator responsive to fluid signals to retract and extend a piston. The actuator includes a cylinder and a pressure piston carried inside the cylinder. Also included is a shaft, and a rod connected to the pressure piston. The actuator further includes a first port for receiving a fluid pressure to move the pressure piston to a first position. The actuator also has a locking mechanism. The locking mechanism has a first and second surface, and both surfaces are movable in response to the fluid pressure at the first port. The surfaces lock the pressure piston in a first position upon removal of the fluid pressure at the first port.

摘要： A fluid parking brake for a rail vehicle having a brake cylinder with a first piston responsive to fluid signals to apply and release the brakes on the vehicle. The parking brake includes a housing having a second piston in the housing and which is coupled to the first piston. An apply port in the housing receives a pressure signal to move the second piston to an apply position. A locking clutch is provided for locking the second piston in the applied position.
