The maintenance of the transmission system is heavy in the selection of oil products. Most of the losses of the transmission system come from the mechanical transmission of the transmission and the main reducer. The transmission and heating of the transmission and the looser adjustment of the gear bearing in the main reducer, or the skidding of the clutch, cause the heat of the clutch assembly and the burn of the driven disk, and so on, which will cause the power consumption to increase. And this part of the power will be transformed into heat scattered into the air, resulting in lower efficiency of mechanical components, and even cause damage to parts. Therefore, it is very important to select the corresponding lubricating oil to prevent parts from damage caused by excessive friction.

The improper selection of lubricating oil in the transmission system, such as oil viscosity, abrasion resistance and viscosity temperature characteristics, can not meet the requirements of different seasons and different conditions of use, and will also cause the reduction of transmission efficiency. For example, under the same conditions, when the winter lubricating oil is used in winter, the friction resistance between parts is increased because of the large viscosity and poor lubricity, which leads to the decrease of transmission efficiency. Therefore, when choosing the use of lubricating oil, we must choose the suitable type of type, and focus on the selection of suitable oil for different climate conditions and use conditions. In addition, we should pay attention to the relatively large consumption of clutch disc, regular inspection and timely replacement to ensure driving safety. If the wheel hub bearing tightness of the driving system is suitable, the front wheel positioning is correct and the tire pressure is normal, it will seriously affect the car's sliding performance. The wheel bearing is too tight, which will increase the friction of the wheel rotation; too loose, the wheel is easily skewed or wagging in the exercise, which increases the friction between the wheel and the ground, resulting in the decline of the car's skidding performance. It is suggested that the owners regularly check and adjust the tightness of the hub in the professional repair shop to keep the best condition of the wheel work. The correct front wheel alignment ensures that the wheels of the vehicle are in a pure rolling state, and ensures the smoothness of the vehicle and the portability of steering. If the front wheel position is not correct, it will cause the car to slide in the front wheel rolling, not only increases the wear of the wheel, but also increases the friction resistance of the car with the ground, which leads to the worse performance of the skating and the increase of the oil consumption.

Tire pressure is also best adjusted according to weather and road conditions. If the temperature is higher now, you can lower the air pressure to prevent bursts. Now the major car repair shop should have four rounds of positioning service, the owner can do other maintenance or maintenance in the normal time, the four wheel positioning project, time cost is more economic, more important is the security improved.

Braking system maintenance to ensure sensitivity

The performance of braking technology is directly related to whether it can give full play to vehicle technical performance, reliability and safety. Good braking performance is a reliable guarantee for safe driving and can also improve the working efficiency of automobiles. However, once the parts of the brake are not adjusted properly, or after the excessive wear and tear, the braking sensitivity of the car is reduced, and the condition of failure or deviation appears. If such a situation has occurred, the owner should immediately adjust the brake system to the maintenance point and replace the worn brake pads. Usually when driving a car, it is best to try the working condition of the brakes first, and ensure normal travel. In addition to the separate maintenance of several systems, it can also clean the chassis and protect the film, postpone the aging and rust of the chassis, and can play a certain resistance to some foreign foreign objects.
