PARKING BRAKE DEVICE FOR RAIL VEHICLE TRUCK BRAKE MECHANISM Russian patent published in 2017 - IPC B61H13/04 B61H13/24 

FIELD: transportation.

SUBSTANCE: parking brake device for rail vehicle truck brake mechanism contains means adapted to rotation for reception of the parking brake force applied by hand, a propeller shaft to transmit the rotational movement to the gear mounted on the brake beam, a brake actuator and transmission means to transmit the parking brake efforts to the drive. Transmission means are represented by a operating shaft, comprising a "shaft-nut" type device to convert rotational movement from the gear to the linear movement towards the brake lever of the brake actuator. The lever is connected to the output actuator pusher.

EFFECT: improved transmission of the parking braking force to the brake actuator and a simplified structure.
