Problems solved by technology

[0002] When the vehicle is going downhill, in order to reduce the wear and thermal degradation of the brakes during frequent braking, exhaust braking is used as a commonly used auxiliary braking method by most heavy trucks, medium trucks and buses. Exhaust braking is performed by air pressure boosting, and all vehicles must have an air source, which makes it impossible for light trucks, off-road vehicles and other vehicles without air sources to use exhaust braking as auxiliary braking

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 The electromagnetic exhaust braking device for automobiles shown in -3 includes an exhaust valve 27 and an electromagnetic drive mechanism 29 that is connected with the rotating shaft 19 of the exhaust valve 27 to make the exhaust port open or close.

[0021] The exhaust valve 27 includes an exhaust pipe body 24 with an exhaust port, a rotating shaft 19 coaxially arranged in the exhaust pipe body 24 and a disc fixed to the rotating shaft 19 to block the exhaust port of the exhaust pipe body 24 23. The exhaust pipe body 24 is provided with a supporting structure to make the rotating shaft 19 rotate stably. The supporting structure includes a bushing 22 coaxially arranged on the surface of the rotating shaft 19. The exhaust pipe body 24 is fixed with a bushing coaxial with the rotating shaft 19, and a bushing. T...

Abstract

The invention discloses an electromagnetic exhaust brake device for automobiles, which comprises an exhaust valve, the exhaust valve comprises an exhaust pipe body with an exhaust port, a rotating shaft coaxially arranged in the exhaust pipe body, and fixed to the rotating shaft, The disc that can block the exhaust port of the exhaust pipe body. The exhaust valve is connected with an electromagnetic drive mechanism that can drive the rotating shaft to open or close the exhaust port. The electromagnetic coil in the casing and the iron core arranged in the electromagnetic coil and capable of moving back and forth by the electromagnetic force are connected between the iron core and the rotating shaft with a push rod mechanism capable of rotating the rotating shaft. In the electromagnetic drive device, the auxiliary push rod and the main push rod are connected flexibly, and there is a compensation spring in the middle. If there is an error in the suction position of the iron core, the movement stroke of the disc is too small, and the iron core and the base cannot be completely attracted or the disc When the sheet cannot be completely closed, the electromagnetic force will compress the compensation spring to make up for the error.

Description

technical field [0001] The invention relates to the technical field of automobile braking devices, in particular to an electromagnetic exhaust braking device for automobiles. Background technique [0002] When the vehicle is going downhill, in order to reduce the wear and thermal degradation of the brakes during frequent braking, exhaust braking is used as a commonly used auxiliary braking method by most heavy trucks, medium trucks and buses. Exhaust braking is performed by air pressure boosting, and all vehicles must have an air source, which makes it impossible for light trucks, off-road vehicles and other vehicles without air sources to use exhaust braking as auxiliary braking. Contents of the invention [0003] The purpose of the present invention is to solve the disadvantages of the above-mentioned background technology, and provide an electromagnetic exhaust brake device for automobiles that can realize brake assistance without an air source. [0004] In order to ac...
