Problems solved by technology

Therefore, effective parking cannot be fully achieved, and there is a serious potential safety hazard.
[0003] In addition, at present, the foot brakes of large, medium and small trucks and trailers are controlled air pressure brakes. The air pressure control is affected by many factors, and it is impossible to allow all the compressed air in the air storage tank to participate in braking in a short period of time, and emergency braking cannot be achieved. purpose, there are serious security risks

Abstract

The invention relates to an emergency braking and parking system, which belongs to part of an automobile brake system and comprises a front axle air cylinder, a hand brake switch, a front axle parkingvalve, a rear axle parking valve, a rear axle air cylinder, a brake cylinder and a spring brake cylinder which are connected through pipelines to form a safe and effective brake parking system. The system is suitable for braking and parking of large, medium and small trucks and trailers; under emergency circumstances, all hubs of the whole vehicle can achieve rapid emergency braking and safe parking, and all the hubs of the whole vehicle can achieve the parking effect during parking. Besides, by additionally arranging a computer controller, an electromagnetic valve and a two-way one-way valve, the emergency braking and parking system can be suitable for special vehicles, and emergency braking safe stopping and parking can be achieved through operation of a control center or a third personin emergency.

Description

technical field [0001] The invention relates to the technical field of vehicle braking systems, in particular to an emergency braking and parking system. Background technique [0002] At present, the parking of large, medium and small trucks and trailers mostly adopts the rear axle of the main vehicle to park, and the spring brake cylinder is often used to stop the air, and the front axle is not parked. When the vehicle is parked on a special road section with a heavy load, it is easy to cause traffic accidents due to insufficient parking force due to the single parking of the vehicle body. Because each wheel hub of the front axle of main vehicle does not have parking function, completely leans on rear axle wheel hub to park. Therefore, effective parking cannot be fully achieved, and there is a serious potential safety hazard. [0003] In addition, at present, the foot brakes of large, medium and small trucks and trailers are controlled air pressure brakes. The air pressur...
