The invention discloses a waste gas braking butterfly valve of a braking system for an automobile and engineering machinery. The butterfly valve comprises a butterfly valve body, a butterfly valve plate and a bracket assembly, wherein the butterfly valve plate is arranged on the butterfly valve body through a butterfly valve plate revolving shaft; the waste gas braking butterfly valve is provided with a waste gas operating cylinder; a cylinder body of the waste gas operating cylinder is provided with a gas inlet; a piston is arranged in the cylinder body of the waste gas operating cylinder; the end part, which extends out of the butterfly valve body, of the butterfly valve plate revolving shaft is provided with a rotating arm assembly; the rotating arm assembly is tightly connected with the butterfly valve plate revolving shaft; and the piston is connected with the rotating arm assembly through a piston rod. When the technical scheme is adopted, the waste gas braking butterfly valve is arranged in the braking system of the automobile or an engineering vehicle, the buffer valve works when an engine conveys air pressure into a braking pipeline, and the output power of the engine is adjusted by controlling the waste gas exhausting speed (increase / decrease) of the engine, so that an auxiliary braking effect is achieved.
Description
technical field [0001] The invention belongs to the technical field of automobiles and construction machinery, and relates to the technology of retarding devices of automobiles or construction machinery. More specifically, the invention relates to an exhaust gas brake butterfly valve of the braking system of automobiles and construction machinery. Background technique [0002] In the prior art, the exhaust brake butterfly valve has poor structural sealing performance, small force and low service life. Contents of the invention [0003] The problem to be solved by the present invention is to provide an exhaust brake butterfly valve for the braking system of automobiles and engineering machinery, the purpose of which is to adjust the output power of the engine to assist braking by controlling the exhaust gas emission rate (large and small) of the engine. effect. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005...
