Problems solved by technology

[0004] Aiming at the problem that the brake cylinder does not have the gap adjustment recognition function and the brake cylinder piston has weak sealing performance in the prior art, the present invention designs a pneumatic brake cylinder, an air brake device and an adjustment gap recognition method, which realizes the gap adjustment in the gap. The function of identifying the size of the gap adjustment during the adjustment process prevents the locking phenomenon caused by additional adjustments and improves driving safety; a piston guide ring and a guide lubricating ring are also set inside the brake cylinder to enhance the cleanliness of the brake cylinder while improving the overall operating efficiency

Abstract

The invention relates to a pneumatic brake cylinder, an air brake device and a gap adjustment recognizing method. The pneumatic brake cylinder comprises a reset unit and a brake unit connected with the reset unit and is characterized in that a gap adjustment unit used for adjusting the brake gap is arranged between the reset unit and the brake unit and comprises a first adjustment module, a second adjustment module and an adjustment limiting module; the adjustment limiting module is arranged between the first adjustment module and the second adjustment module and comprises a limit spring and a limit base; and the limit spring is fixedly connected with the limit base and the first adjustment module so as to ensure that the size of the brake gap can be controlled within a certain range, the function of recognizing the gap adjustment size in the gap adjustment process is achieved, the locking phenomenon caused by extra adjustment is prevented, and the travelling safety is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle braking, and in particular relates to a pneumatic brake cylinder, an air brake device and an adjustment gap recognition method. Background technique [0002] Brake cylinder is an important part of rail rolling stock. Most of the existing brake cylinders are pneumatic brake cylinders, which are generally used in high-speed railway locomotives, urban rail vehicles and other rail rolling stock with disc brakes. The pneumatic brake cylinder is an important executive part in the air brake device of the locomotive and vehicle. By converting the air pressure into thrust, and then pushing the clamp lever and other components to make the brake pad and the brake disc produce friction, so as to control the entire vehicle brake. [0003] During the braking process of the pneumatic brake cylinder, the distance between the brake disc and the brake disc becomes larger due to the wear of the brake disc and the b...
