1. ABS introduction

1.1 what is ABS

ABS is the abbreviation of anti lock braking system, which is an electronic system to control and monitor the vehicle speed during braking. It works through the conventional braking system, and can improve the active safety of the vehicle. When ABS fails, the conventional brake system still works. ABS system mainly consists of ECU, ABS solenoid valve, wheel speed sensor and harness.

1.2 what are the advantages of vehicle ABS installation

In case of emergency braking, the maneuverability of vehicle direction is maintained; the braking distance is shortened and optimized. On the low adhesion road surface, the braking distance is shortened by more than 10%; on the normal road surface, the optimal utilization ratio of road adhesion coefficient - that is, the optimal braking distance is maintained. Reduced traffic accidents. Reduce the driver's mental burden. Reduced tire wear and maintenance costs.

2. Trailer ABS relay valve

2.1 function of ABS relay valve of Trailer

ABS relay valve is a main executive part of ABS system. It receives electric signal from ECU to charge, exhaust and maintain pressure of brake chamber. Compared with ordinary ABS solenoid valve, the flow of trailer ABS relay valve is larger. One solenoid valve can control the air supply of three brake chambers at the same time. Therefore, compared with conventional ABS solenoid valve, the cost advantage of installing Trailer ABS relay valve is very obvious.

2.2 ABS relay valve of our company

Our company's Trailer ABS relay valve was listed in 2005. After continuous test and improvement, the product performance is stable and the annual output is more than 20000.
