Brief introduction of semi-trailer brake system design and trouble shooting (Three）)

ABS Anti-lock braking system to be assembled

The braking system of semi-trailer is divided into two parts: tractor and trailer. The traditional braking system controls the whole braking system through all kinds of pure mechanical parts, which can not sense the contact condition of every axle, tire and the ground. In the event of an emergency, the braking system uses a fixed braking mode to control the vehicle, which is beyond the reach of good driving skills

Happiness comes from safety. Simply put, the ABS system computes complex signals collected by sensors and a central processing unit that precisely controls the ABS pneumatic control valve, adjusting the distribution of braking forces on each tire, be aware of the vehicle's braking status at all times, just as the driver has many helpers to help you control the vehicle. Although the same is a foot brake action, its role is completely different

The use of automatic brake adjustment arm matters for attention

Auto-adjusting arm was widely used in bus braking system in the early days. With the upgrade of high-end truck technology, the products with auto-adjusting arm have come into our sight gradually. The automatic adjusting arm saves the heavy maintenance work of manually adjusting the brake clearance (brake grain and brake pad clearance) , and maintains the consistency of the braking effect

It should be noted that the brake pads or brake hub wear too much, acting on the brake shoes of the brake camshaft can not return, causing“Drag wear” or even“Embrace”, causing accidents. Therefore, equipped with automatic arm of the vehicle, in strict accordance with the provisions of the maintenance norms, inspection, maintenance and replacement

ABS system sensors installed in the axle bushing fixed bracket, the need for a relatively dry, clean environment to ensure normal work. When choosing to replace the brake pads, to choose non-asbestos components of high-quality products, some so-called“Semi-metal, all-metal” asbestos brake pads generated by the wear debris adhesion in the brake hub parts of the surface, causes the ABS sensor to fail. The hard material of brake pad can also cause irreparable damage to the brake hub, and the brake system is also prone to overheating
