Abstract

The invention belongs to the field of rail vehicle clearance compensation and provides a door clearance compensator and a rail vehicle. The door clearance compensator comprises a floor body, a pedal body and a driving mechanism; the floor body is configured to be fixedly embedded in a mounting notch reserved in a vehicle body door area floor; the pedal body is connected to the bottom surface of the floor body in a sliding manner; and the driving mechanism is configured to drive the pedal body to horizontally stretch out and draw back along the floor body. An existing clearance compensator anda door system of a vehicle are integrally designed, independent control over the door clearance compensator cannot be achieved, an existing door clearance compensator of a pneumatic structure appliesan overturning structure, and as a result, the compensator occupies large space, is complex in structure, and low in reliability. With the door clearance compensator and the rail vehicle of the invention adopted, the above problems can be solved.

Description

Technical field [0001] The present invention relates to the technical field of rail vehicle clearance compensation, in particular to a door clearance compensator and a rail vehicle. Background technique [0002] The door clearance compensator, as the name implies, is used to compensate the gap between the door and the platform. After parking, the pedal of the door clearance compensator extends toward the platform to facilitate passengers getting on and off the train; the pedal direction of the door clearance compensator Retract away from the platform so as not to affect the normal driving of the vehicle. [0003] However, the current existing door lash compensators have the following shortcomings: (1) They are all integrally designed with the door system of the vehicle, and cannot achieve individual control of the door lash compensator; [0004] (2) The door clearance compensator of the existing pneumatic structure adopts a flip structure, which takes up a large space, has a complex...
