Abstract

The invention provides a powerful double-pipeline brake cylinder which comprises an output pump and a reinforcement pump. The output pump comprises a first pump body, a first push rod and a first piston. The first piston is located in the first pump body. The first push rod is fixedly connected with the first piston. The reinforcement pump comprises a second pump body, a second push rod and a second piston. The second piston is located in the second pump body, and the second push rod is fixedly connected with the second piston. The second pump body is fixedly arranged on the rear portion of the first pump body, a through hole is formed between the first pump body and the second pump body, and one end of the second push rod penetrates through the through hole and abuts against the first push rod. The technical problem that the brake performance of a vehicle is poor due to the fact that the jacking force of an existing brake cylinder is small can be solved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a powerful dual-pipeline brake cylinder. Background technique [0002] The brake cylinder is an indispensable chassis brake part of the brake system. Its main function is to push the brake pads, and the brake pads rub against the brake drum to reduce the speed of the vehicle and stop it. Trucks for transportation often have to run long-distance transportation, and the quality of the brake cylinder plays an important role in whether the long-distance transportation of trucks is smooth and safe. The brake cylinder of existing truck generally comprises pump body, is located at the air inlet above pump body, is enclosed within the film in pump body, is located at the piston in pump body, push rod and the return spring etc. that are enclosed within on push rod. The main disadvantages of the existing brake cylinders are that the film is easily damaged, and the braking effect is not...
