Problems solved by technology
[0002] At present, most large vehicles such as buses, trucks and trailers use air brake systems. Although this brake method is widely used, the biggest problem with this brake system is that the rear wheel brake air pipeline is too long, which makes the brake response time slow. Too long, affecting the braking performance
Although the rear wheel braking part of most air brake systems is equipped with a relay quick release valve to reduce the harm caused by this problem, the installation of this device can only reduce the delay of the peak pressure, and cannot shorten the rear wheel braking. Delay in motion response time
[0003] Moreover, the existing braking system does not have an automatic braking function in emergency situations. When the driver is fatigued or other special circumstances cause the driver's braking reaction time to be too long, or the driver does not respond to the braking action when braking is required , leading to many accidents

The invention relates to an electronically controlled rear-wheel air brake system, including a rear-wheel single-cavity air brake valve and a rear-wheel brake air storage cylinder which is connected with a rear-wheel brake drive device in series by a push rod of the rear-wheel brake drive device; the push rod of the rear-wheel brake drive device is also connected with a position sensor of the rear-wheel brake drive device; the rear-wheel brake drive device is connected with the output end of an electronic controller; the position sensor of the rear-wheel brake drive device is connected with afirst input end of the electronic controller; a second input end of the electronic controller is connected with a brake pedestal position sensor; the electronic controller receives a brake pedestal action signal of the brake pedestal position sensor and outputs a voltage pulse signal; the rear-wheel brake drive device linearly controls the rear-wheel single-cavity air brake valve by the pushing rod of the brake drive device according to the voltage pulse signal of the electronic controller, and the rear-wheel brake drive device sends the action signal of the rear-wheel brake drive.
Description
technical field [0001] The invention belongs to the field of automobile braking, in particular to an electronically controlled rear wheel air brake system, and further relates to an electronically controlled rear wheel air brake system for automatic braking. Background technique [0002] At present, most large vehicles such as buses, trucks and trailers use air brake systems. Although this brake method is widely used, the biggest problem with this brake system is that the rear wheel brake air pipeline is too long, which makes the brake response time slow. Too long will affect the braking performance. Although the rear wheel braking part of most air brake systems is equipped with a relay quick release valve to reduce the harm caused by this problem, the installation of this device can only reduce the delay of the peak pressure, and cannot shorten the rear wheel braking. delay in response time. [0003] Moreover, the existing braking system does not have an automatic braking...
