The braking performance, synchronization, and safety of the trailer have been qualitatively improved, which can be said to lead a revolution in the brake system of semi-trailers in China. Semi-trailer three-bridge synchronous valve, first-generation mechanical ABS three-bridge synchronous emergency relay valve, second-generation mechanical ABS three-bridge synchronous emergency relay valve, third-generation mechanical ABS three-bridge synchronous emergency relay valve. Light car light brake, heavy car heavy brake. Light load soft brake, heavy load brake spirit and other characteristics. Anti-locking trailer king (automatic stepless variable pressure emergency relay valve). 
At present, the common problem of the semi-trailer brake system is that the trailer axle is light in weight, easy to drag, unreasonable deceleration, and serious tire wear, which leads to extended braking distance. The braking distance is increased, so that safety cannot be effectively guaranteed. In order to improve the above situation and ensure driving safety, our company has developed and designed. Manufacture of fully automatic stepless variable pressure emergency relay valve for semi-trailer (anti-locking trailer king). This product meets the requirements of international standards. The multi-axle braking sequence starts from the last axle, and each axle is delayed by 0.04 seconds to achieve reasonable synchronous braking of the multi-axle, thereby greatly increasing the braking deceleration and increasing the service life of the tire. The product has reached international standards in terms of appearance, structure, and theoretical data. Proof of customer feedback over the years (anti-lock trailer king). No-load, standard-load and heavy-load achieve the effect of synchronous emergency braking, which makes up for the problems of traditional ordinary relay valves, which are easy to drag to no load, insufficient ABS heavy-load braking force and short service life. It effectively solves the phenomenon of severe tire wear and solves the disadvantage that the trailer must be switched on and off. This product is resistant to freezing under low temperatures in winter in the north. The anti-lock trailer can increase the mileage of tires by more than 45%, and the mileage of special vehicles, oil tankers and other models can reach more than 100%. Using this valve can save RMB 10,000 to 20,000 compared with other products and improve the owner's operating profit. .
