Knowledge points about semi-trailer cabin connection and braking

The semi-trailer bed has its own brackets. First, semi-trailer manufacturers use brackets to support the vehicle. There are support rods at the joint between the carriage and the main vehicle. By pulling out the lever, riders steering the semitrailer can exit the box while driving forward.

The fixed bracket should be supported by its own legs. If the relative height is not enough, you can put some items under it until there is a small gap between the board and the bracket. Then there is a light guide on the right side of the bed. You pull it out and clamp it, and then separate the main line tasks of the gas pipe and the light. When you turn on the tractor, they are separated. The truck uses a side-tilting tipping bucket method to unload the truck, which can effectively improve the transportation efficiency of the bulk cargo handling machinery.

The side beams of the semi-trailer are fully automatic arc welded, the window frames of the tablet semi-trailer manufacturer are shot blasted for rust removal, and the load-bearing beams pass through the side beams and are welded by overall electric welding. The suspension adopts non-independent thick steel plate stamping stiffness suspension, which is composed of a series of leaf springs and suspension brackets. It has reasonable structure, strong rigidity and good compressive strength, and is used to support point loads and reduce impact.

1. The material of the gas storage tank is poor, the pump valve is corroded and polluted, and the pump valve is damaged. At present, the iron gas storage tanks used by most manufacturers on the market are easily corroded, causing damage to the pump valve. A gas storage that meets the standards should have functions such as anti-corrosion, anti-rust treatment, pressure stabilizing pipes, and temperature reduction. However, most of the gas storage tanks we use do not meet the requirements. This will cause serious leakage and damage to the truck's emergency brake valve and brake cylinder.

2. The layout is different. One controls three. The gas tank gives gas to the site. The manager is unable to meet the requirements. When operating the brake pedal, the response is slow and the air supply cannot keep up. Often the emergency brake valve (brake king) with too many pneumatic valves is used, which then locks up the brake system. The front air supply is delayed, the mid-range air supply is too large, the brake pedal is difficult to use and control, the braking distance is long, and the wheels are locked.

In the absence of ABS, the standard and reliable hanging bucket braking system equipment should be dual-control switch and triple-control. Compared with one control and three controls, the two control and three layout layout trailer braking system is more stable, and the tire and wheel locking situation is significantly reduced.
