1, the body of each hinge hole shaft rotation. 2. The impact and sliding between the lock tongue and the lock, and the intermittent impact between the limit plate surface of the lock tongue shoulder. 3, The sliding of the glass lifter gear contact teeth. 4. The looseness of the hinge hole shaft causes friction between the lower surface of the door and the door frame after the door is lowered. The lower surface of the hood and the upper surface of the radiator and the upper surface of the fender are in vibrational contact with relative misalignment and the like. The bolt holes after the loosening of the bolts of the sheet metal parts are worn, resulting in an increase in the diameter of the holes. What are the causes and components of cleaning the body surface of the sweeper vehicle? 1, Reason: There is muddy water on the surface of the metal, and oxidation occurs and causes corrosion. 2. After welding, no rust treatment was used to cause corrosion. 3, chemical exposure and chemical corrosion. Behind the cab is a skirt and a skirt. What are the causes of cracks or breaks in the body of the sweeper? Causes of cracks or breakages in the car body; internal stress in the process of forming or welding of sheet metal parts; when the sweeping vehicle is running, the body sheet undergoes constant vibration to subject the sheet metal parts to alternating loads; the car accelerates rapidly, and emergency braking occurs. When turning sharp corners, the vehicle body is subjected to inertial force and centrifugal force. When the sweeper sweeps the road surface with poor road conditions, each sheet metal part is subjected to a torsional force. The body has cracked or broken parts.

How do sweeping cars prevent body wear?
Cleaning the surfaces of the sheet metal parts of the sweeper vehicle that are in contact with each other causes wear due to relative motion caused by the force. The greater the force applied, the longer the action time, and the lower the surface hardness of the material, the more severe the wear. The following parts of the body are prone to wear:
