Abstract

The invention relates to a relieving device of a railway vehicle basic braking parking cylinder. The relieving device is fixed to the side face of an end cover of the parking cylinder and comprises a box body, a center shaft, a bolt and a driver. The center shaft is located in the box body and can slide in the direction of the axis of itself. The rear end of the bolt and the center shaft are fixed, the center shaft is sleeved with the driver, and the front end of the bolt is provided with a head portion and a hook portion, wherein the head portion can be inserted between teeth of a ratchet wheel seat and the hook portion is matched with a locking pin. The two sides of the driver are connected with draw cords respectively, and the draw cords are parallel with the center shaft. A first stopping block used for preventing the head portion of the bolt from deviating and a second stopping block used for preventing the bolt from overturning are fixed to the end cover. Handles of the two draw cords are arranged on the two sides of a vehicle body respectively, and relief of parking brake can be realized by simply pulling the manual relieving draw cord on any side of the vehicle body.

Description

technical field [0001] The invention relates to a foundation brake of a rail transit vehicle, in particular to a cross shaft anti-rotation balance mechanism of the brake. Background technique [0002] The basic brake parking cylinder of the rail transit vehicle is mainly to ensure that the vehicle has parking brake requirements under certain slope conditions. Parking braking is generally achieved by the active force of the energy storage spring in the parking cylinder. The compression and expansion of the energy storage spring in the parking cylinder is mainly realized by compressed air: when the compressed air is discharged, the parking brake is applied; when the compressed air is charged, the parking brake is released. If compressed air is not available to relieve the foundation brakes where the parking brake is already applied (such as when the vehicle is parked), the release rope can also be manually operated to relieve the parking brake. [0003] The existing manual r...
