Chassis maintenance:

The maintenance of automobile chassis is often regarded as optional. It is far less important than the engine and body. In fact, whether the maintenance of the automobile chassis is directly related to the safety, handling, comfort, and economy of the car. The key performance must not be taken lightly. Car chassis maintenance and engine maintenance have many similarities and need to be checked in time.

1. Regularly check the oil of each assembly

This includes transmissions, braking systems, power steering systems, etc. On the one hand, it must be strictly supplemented or replaced regularly at a special maintenance service station in strict accordance with the time stipulated in the manual. By the way, check to see if the oil in each storage tank is between the upper and lower tick marks. If it is lower than the lower tick mark, replenish it in a timely manner. If the oil level drops faster, it means that the system has a leak and needs to be immediately Check for leaks and repair in time.

2.Replace worn brake pads in time

The two types of friction linings, brake linings, and clutch linings are consumables, which will wear out after a period of use and lose their original functions. If they are not replaced in time, it will easily cause a car accident. Generally, there are corresponding warning lights on the car, and a warning signal will be issued in time to remind the user to replace it.

On buses, sometimes rivets are used to rivet the friction plates to the steel back. When we sit on the buses, we will hear the driver's sharp noise when braking, which is to warn the driver that the friction plates have worn the rivets. It must be replaced immediately. However, most cars have now changed the friction plate to the steel back by gluing. Until the friction plate is ground to the end, the metal and metal will make a direct sound. At this time, it is too late to replace the friction plate. Therefore, modern cars are equipped with electronic signal sensors. The brake indicator light on the dashboard will light up when the friction plate is 1.5 mm left, which reminds the driver to replace the friction plate.

By the way, in rainy and humid weather, the friction plate will absorb moisture and the friction force will be significantly reduced. At this time, when the car is just started, the first step on the brake and clutch a few times, use the heat generated by friction to evaporate the water on the friction plate and then leave the car.

3.Four-wheel positioning to ensure safety

If you don't look closely, the four wheels on the car seem to be standing upright on the ground. In fact, if you use an instrument to measure them, you will find that they are deflected by one more angle in the three planes of X, Y, and Z, but the values Very small, usually only 0.5 to 2 degrees, not visible to the naked eye. Don't underestimate these three small deflection angles, it determines the steering performance of the car. If a car crashes or is used for a long time and changes due to wear, the handling will be greatly reduced. Therefore, if you feel something strange when operating the steering wheel, you should go to a regular auto repair shop or a professional four-wheel alignment inspection station to check and make corresponding adjustments. It doesn't cost much, but it ensures safe driving.

4.Selective spraying of chassis protective film

Cars often encounter rainy days, and the chassis is susceptible to rust when exposed to water; driving on poor roads, flying wheels will also pick up debris and hit the chassis. Therefore, some manufacturers recommend spraying a protective film on the chassis to improve the rust prevention ability, reduce impact damage, and extend the life of the chassis.

However, this also requires specific analysis. Many middle- and high-end cars now use double-sided galvanized steel, and wax injection is used in the spaces where water may be poured. Generally, it is not a problem for 10-15 years. Some cars are all covered with rust-proof steel plates at the bottom, which not only avoids the infiltration of water but also reduces aerodynamic resistance. There is no need to add more to this type of car.
