Tips How to check and maintain the car chassis

Transmission system - choose a good lubricating oil

Most of the losses in the drivetrain come from the mechanical transmission of the transmission and the main reducer. The sound of the transmission, the heat and the improper adjustment of the tightness of the gear bearing in the main reducer, or the slippage of the clutch, causing the clutch assembly to heat up and the driven disc burn, etc., will cause the power consumption to increase. This part of the power will be converted into heat and dispersed into the air, resulting in reduced efficiency of mechanical components and even damage to parts. Therefore, it is very important to select the corresponding lubricant to prevent part damage caused by excessive friction.

Improper selection of transmission system lubricating oil, such as the viscosity, wear resistance and viscosity temperature characteristics of the oil, can not meet the requirements of different seasons and different conditions of use, and will also cause a reduction in transmission efficiency. For example, under the same conditions, when using summer lubricating oil in winter, due to large viscosity and poor lubricity, the frictional resistance between various parts increases, which in turn leads to a decrease in transmission efficiency.

Therefore, when choosing to use lubricating oil, we must choose the variety that suits our own models, and pay attention to the selection of suitable oil products for different climatic conditions and use conditions. In addition, it should be noted that the clutch plate consumption is relatively large, and it is necessary to check regularly and replace it in time to ensure driving safety.

Braking system – ensures sensitivity

The quality of braking technology performance is directly related to whether the technical performance of the car can be exerted, the reliability of work, and the safety of driving. Good braking performance is a reliable guarantee for safe driving, and it can also improve the efficiency of the car. However, once the parts in the brake are improperly adjusted, or there is excessive wear, the brake sensitivity of the car is reduced, and the failure or deviation occurs. If this has already happened, the owner should immediately go to the service point to adjust the braking system and replace the brake pads that have been worn. Usually, when driving, you can try the working state of the brakes first to ensure that you can travel normally.

Driving system - take care of the tires

Whether the elasticity of the wheel hub bearings in the automobile driving system is appropriate, whether the front wheel positioning is correct, and whether the tire pressure is normal will seriously affect the taxiing performance of the car. The wheel hub bearing is too tight, which will increase the friction of the wheel rotation; too loose, the wheel is easy to skew or sway during driving, which increases the friction between the wheel and the ground, resulting in a decrease in the taxiing performance of the car. It is recommended that car owners regularly go to the professional repair shop to check and adjust the elasticity of the wheel hub to keep the wheel rim working in good condition.

Correct front wheel positioning can ensure that the wheels are in a pure rolling state when the car is running, and can ensure the smooth driving of the car and the lightness of the steering. If the front wheel positioning is not correct, it will cause the car to slip in the front wheel when driving, which will not only increase the wear of the wheel, but also increase the frictional resistance of the car with the ground when driving, which will lead to poor sliding performance and increase fuel consumption. Now the large car repair stores should have four-wheel positioning services, owners can usually do other maintenance or maintenance when the way also do the four-wheel positioning project, time time is more economical, more importantly, the safety is improved.

The air pressure of the tires is also adjusted in a timely manner according to changes in weather and road conditions. Under higher temperature conditions, the air pressure can be lowered to prevent puncture tires.

In addition to the separate maintenance of several systems, the chassis can also be cleaned and protected by the upper film, delaying the aging and rusting of the chassis, and playing a certain role in resisting some foreign bodies.
