Abstract

The invention discloses a trailer line control unit and a brake system, the line control unit is arranged in the trailer brake system, the line control unit comprises a pressure sensor, a trailer control valve, a data bus and an emergency relay valve, the pressure sensor is arranged at a position close to a trailer pneumatic brake control interface and is connected with the trailer control valve through the data bus; the pressure sensor receives an air brake signal through the trailer air brake control interface and converts the air brake signal into an electric brake signal; the trailer control valve and the emergency relay valve are arranged on the trailer chassis; and the trailer control valve is used for receiving the electric braking signal sent by the pressure sensor and controlling the braking state of the trailer according to the electric braking signal. A control air medium led out by the foot brake valve of the tractor can be prevented from passing through a pipeline of more than ten meters, delay time is shortened, and therefore the problem of trailer brake coordination is effectively solved, meanwhile, use of adjusting valves is reduced, and installation cost is reduced. The trailer line control unit and the brake system can be widely applied to the field of motor vehicle braking.

Description

technical field [0001] The invention relates to the field of motor vehicle braking, in particular to a trailer line control unit and a braking system. Background technique [0002] The trailer itself has no power drive, and the traction is provided by the tractor. During the braking process of the trailer, there are problems such as poor coordination between the main vehicle and the trailer, prone to folding, flicking, rollover and other phenomena that affect driving safety, and serious tire wear and other problems. In order to solve the above problems, the trailer braking system can be relieved by matching the ABS anti-lock braking system. Then, although the ABS anti-lock braking system can effectively alleviate the braking performance and safety problems of the trailer, it does not solve the problem of incoordination between the main trailer and the trailer. [0003] At present, the brake action of the trailer is operated through the derivation of the foot brake valve of...
