Pneumatic intelligent electronic parking braking device

Abstract

The invention discloses a pneumatic intelligent electronic parking braking device which comprises an air cylinder, a pressure switch, a parking braking air chamber and a braking controller, wherein the air cylinder, the pressure switch and the parking braking air chamber are sequentially connected through air channels, and the braking controller is electrically connected with a braking switch and the pressure switch. A pneumatic integrated electronic parking braking valve and a baroceptor are sequentially arranged on the air channel between the pressure switch and the parking braking air chamber, the pneumatic integrated electronic parking braking valve and the baroceptor are further respectively connected with the braking controller in an electric mode. The parking braking device is simple in structure, convenient to arranged flexibly, and timely, safe and reliable in parking braking.

Description

technical field [0001] The invention belongs to the technical field of pneumatic brake systems, in particular to a pneumatic intelligent electronic parking brake device. Background technique [0002] At present, the parking brake device of medium and heavy vehicles adopts the pneumatic manual parking brake device. This kind of pneumatic manual parking brake device mostly adopts the principle of "air break brake". Apply the parking brake. Its operation is cumbersome, especially when starting uphill, if the driver is inexperienced in manipulation or makes a manipulation error, it is easy to slip backward. Cars equipped with automatic transmissions cannot achieve good hill starts with this type of parking brake. If the coordinated control effect of the parking brake and the transmission is poor, it will cause the car to slip, the wear of the clutch and the brake, and even cause the engine to be suffocated and stalled. [0003] In order to solve the problems existing in the h...

AI Technical Summary

Problems solved by technology

[0004] 1. Its semi-automatic and fully automatic control scheme cancels the mechanical hand brake switch in the cab and replaces it with an electronic switch button. Although it solves the space problem, it also brings that if the system fails, the driver will not be able to Carrying out the parking or releasing the parking brake manually will bring unnecessary trouble and danger, and the safety and reliability are not enough;

[0005] 2. There are differences in the system structure for realizing semi-automatic and fully automatic control schemes, which need to be changed to meet the needs of different consumers, and the flexibility of installation layout is poor
