The car broke down when it was away from the repair point. It was really a headache. If you have a car, you should pay attention to the maintenance of the car after you have a car. When it comes to the maintenance of the car, chassis care is most easily ignored by the driver's friend, but the importance of the maintenance of the chassis in winter or wet weather is obvious. In winter, chassis maintenance and chassis cleaning and rust treatment are essential. First of all, we should clean the chassis thoroughly. If the dirt on the chassis is too much, it should be washed with the cleanser to make the chassis reveal the original "color", so that the antirust nursing can begin. In a professional beauty salon, the car can be lifted to the lifting frame for chassis cleaning, wiping and rust prevention. In this case, we must pay attention to that after cleaning, we must wait until the moisture on the chassis is dry. During nursing, we must maintain uniform spray coating to form a layer of durable and uniform rust preventive coating. After 5-10 minutes of air drying, the chassis anti rust treatment will be completed. After the professional chassis care, it does not mean that there is no loss, there is a misunderstanding, that is, often people in order to love the car will wash the car, which often add some cleaning agent, at this time, please pay attention to the basic cleaning agent, washing clothes powder, washing body and chassis, otherwise the body and the chassis, otherwise it will shadow The effect of rust prevention and the time of rust prevention are shortened. It is suggested that you go to the professional beauty shop to do the bottom board nursing. The quality of it has a simple way to try out: the chassis of the anti rust nursing care is almost no beads after the high pressure water spray rinse. This effect only represents the genuine nursing, and can be a good antirust protection effect. When the chassis is damaged in the field or away from the car repair place, the following emergency methods can be used to open the vehicle to the condition of the car repair. It can be used as a small cushion with iron and copper skin at the pipe joint of the sub pump. The pipe is blocked, then the screw is tightened, or the fracture is flattened and curled up, so that the wheel can not be used as brake. But this may result in unilateral braking and safety when driving. Alcohol or liquor can be used instead of water. The skin bowl is soaked in hot water for 10 minutes for -20 minutes, and the oil content on the bowl is removed so that the skin bowl can be restored to its original size. For the less serious friction film, it can be turned over. If the ablation is serious, it can be made of several layers of cotton cloth or canvas, and the wire or iron wire can be used to pass through the holes on the steel sheet to make it fixed. When driving a vehicle, it should start smoothly and shift gears quickly. In the bumper or other places that do not affect the driving, unload a screw that is similar to the total length of the ball, instead of the broken joint. After loading the steering knuckle arm and nut, the screw is riveted with the hammer. Damage to the gear of the three axle automobile differential gear, such as damage to any one of the rear axle differential, can remove the axle and half axle of the bridge and continue to drive. If the front differential is damaged, the hub connection can be removed and then continued.
