Suspension device: connects the wheels and the frame to reduce the impact of road bumps on the body. 3. Shock absorber: absorbs vibration energy and improves the driving stability of the vehicle. 4. Braking system accessories 1. Brake discs and brake pads: core components of the braking system, generating braking force through friction. 2. Brake fluid: medium for transmitting braking force, transmitting the driver's braking operation to the braking system. There are also many auxiliary systems and accessories, such as ABS anti-lock braking system, EBS electronic control braking system, tire pressure monitoring system, etc., all of which are designed to improve the safety performance and driving stability of the truck.

Observe the appearance and quality of accessories 1. Geometric dimensions: Check whether the parts are deformed. You can roll the shaft parts along the glass plate for a circle and observe whether there is light leakage at the joint between the parts and the glass plate to determine whether they are bent. 2. Joints: Check whether the joints of the parts are flat, and whether there are burrs, indentations, damage or cracks. 3.

If the sealing sleeve is damaged, the packaging paper is lost, or the anti-rust oil or paraffin is lost during purchase, it should be returned or replaced. 2. Glued parts: Accessories composed of two or more parts, no looseness is allowed between the parts. If looseness is found, it should be replaced. VI. Test rotating parts and assembly parts 1.
