There are two kinds of chassis protection, one is plastic enclosure and the other is protective armor. Chassis sealing is a kind of chassis care technology. A kind of flexible rubber resin with high adhesion, high elasticity, high corrosion resistance and moisture resistance is sprayed on the chassis to isolate it from the outside world, thus achieving the effects of anti-corrosion, anti-rust and anti-collision, and at the same time isolating some noise from the bottom. Plastic packaging construction of chassis is more troublesome. First, carefully remove the oil stains on the chassis, and then thoroughly remove the asphalt and oil stains with a special cleaner before drying. Any negligence in these treatments will affect the firmness of "plastic packaging". Then the transmission shaft, exhaust pipe and other parts that need heat dissipation are sealed with tape and sprayed with plastic. In order to avoid accidental damage and affect its normal operation. Chassis Protective Armor In order to overcome the shortcomings of traditional automobile chassis packaging in terms of protective strength, durability and stability, a new type of automobile maintenance project-"Chassis Protective Armor" was produced. It means that the chassis will be sprayed with more advanced materials than the "chassis sealing plastic". "Chassis protective armor" is a material infrastructure with rubber sealant instead of oil, paint, asphalt and so on. According to the different physical and chemical characteristics of various materials, multi-component combined products are developed to make these products have excellent characteristics such as high density, waterproof and antirust, acid and alkali resistance, heat and cold resistance, elastic and wear resistance, non-toxic and environmental protection, thus overcoming the shortcomings of traditional materials in terms of protective strength and stability.

Chassis maintenance:

1, the loss of transmission system mostly comes from the mechanical transmission of transmission and final drive. The noise and heat of the transmission, improper adjustment of the tightness of the gear bearing in the main reducer, or clutch slipping will cause the clutch assembly to heat up and the driven plate to burn out, which will increase the power consumption. This part of the power will be converted into heat and dispersed into the air, which will reduce the working efficiency of mechanical parts and even cause parts damage. Therefore, it is very important to choose suitable lubricating oil to prevent parts from being damaged due to excessive friction.

2. Improper selection of transmission system lubricating oil, such as oil viscosity, wear resistance and viscosity-temperature characteristics, can not meet the requirements of different seasons and different use conditions, which will also lead to the reduction of transmission efficiency. For example, under the same conditions, when summer lubricating oil is used in winter, due to its high viscosity and poor lubricity, the friction resistance between parts increases, resulting in a decrease in transmission efficiency. Therefore, when choosing to use lubricating oil, you must choose the variety suitable for your own model, and pay attention to choose the appropriate oil according to different climatic conditions and use conditions. In addition, it should be noted that the consumption of clutch plates is relatively large, so it should be checked regularly and replaced in time to ensure driving safety.

3. Whether the wheel hub bearing tightness is appropriate, whether the front wheel positioning is correct and whether the tire pressure is normal in the automobile driving system will seriously affect the taxi performance of the automobile. Too tight hub bearing will increase the friction of wheel rotation; If it is too loose, the wheels are prone to skew or sway during driving, which will increase the friction between the wheels and the ground and lead to the decline of the sliding performance of the car. It is recommended that the owner regularly check and adjust the wheel tightness in a professional repair shop to keep the wheel rim in the best working condition.

4. Correct front wheel positioning can ensure that the wheels are in a pure rolling state when the car is running, and can also ensure the smoothness and portability of the car when turning. If the front wheel is not positioned correctly, it will cause the front wheel to slip when driving, which will not only increase the wheel wear, but also increase the friction resistance between the car and the ground when driving, resulting in poor sliding performance and increased fuel consumption. Large automobile franchise stores should have four-wheel positioning service. Car owners can also do four-wheel positioning projects when doing other maintenance or overhaul at ordinary times, which saves time and, more importantly, improves safety.
