The Reasons For The Poor Braking Performance Of The Semi-trailer
The semi-trailer is more convenient to use, easy to load, easy to unload, etc. It is very simple to operate. For the simple, economical and practical operation of the semi-trailer, we should pay attention to some problems when using the semi-trailer. Although the operation of the wingspan semi-trailer is simple, everyone must follow the correct operation method.
1. The material of the air storage cylinder is poor and rusted and polluted, and the pump valve is scrapped. At present, the iron gas storage cylinders used by most manufacturers in the market are easy to rust and cause damage to the pump valve. A qualified air storage cylinder should have the functions of anti-corrosion, anti-rust, voltage stabilization and cooling. And most of the gas storage tanks we use do not meet the requirements. As a result, the emergency relay valve of the trailer and the brake wheel pump have serious leakage and wear problems.
Second, the difference in layout. One control and three, the air reservoir only supplies air at one position, and the diameter of the pipe is difficult to meet the requirements. When the brake pedal is actuated, the response time is slow and the air supply cannot keep up. Usually, an emergency relay valve (brake king) is used that exceeds the standard air supply, and then the brake locks up. The front-end air supply is delayed, the mid-end air is too large, the brakes are difficult to use, difficult to control, and the braking distance is long and locked. In the absence of ABS, the standard and reliable trailer braking arrangement should be two-control-three. Compared with one-control-three, the trailer braking with two-control-three layout provides smoother braking and greatly reduces tire locking. , At present, in addition to CIMC and other manufacturers using the standard two-control three cloth form, and even some export models are also equipped with a separate trailer parking brake handle. In the period, the manufacturers almost without exception adopted the one-control-three-fabrication method.
