An owner with certain experience in car maintenance told the teacher that his car had a chassis armor installed when it was new, and later he paid great attention to the maintenance of the chassis. The car has been bought for two or three years and still looks like new. He also told the reporter that even after installing the chassis armor, one cannot be complacent and neglect the maintenance of the chassis. In fact, regular maintenance of the chassis is very important, especially for those who do not take any rust prevention measures. To properly maintain an ordinary chassis, you need to start from the following three systems.
Transmission System - Select Good Lubricants
Most of the wear in the transmission system comes from the mechanical transmission of the gearbox and the main reducer. Improper adjustment of the sound, heat generation of the gearbox, and the looseness of the gear bearings in the main reducer, or the clutch slipping, causing the heating of the clutch assembly and the burnout of the driven disc, will lead to an increase in power consumption. This part of the power will then be converted into heat and dissipated into the air, reducing the efficiency of the mechanical components and even damaging the entire machine. Therefore, choosing the appropriate lubricant is very important to avoid excessive friction that causes part damage. If the selection of transmission system lubricants is inappropriate, such as oil viscosity, wear resistance, and visco-temperature characteristics not meeting the requirements of different seasons and usage conditions, it will also lead to a decrease in transmission efficiency. For example, under the same conditions, using summer lubricating oil in winter, due to high viscosity and poor lubrication, increases the friction resistance between each component, thereby leading to a decrease in transmission efficiency. Therefore, when selecting and using lubricating oil, it is necessary to choose the type suitable for your vehicle model, and according to different weather conditions and usage conditions, it is also necessary to select the appropriate oil product. In addition, note that the clutch plate consumes relatively more, so regular inspections and timely replacements should be made to ensure driving safety.
Driving System - Maintain Tires
Whether the wheel hub bearing tightness is appropriate, whether the front wheel alignment is correct, and whether the tire pressure is normal in the car driving system will greatly affect the car's coasting performance. Too tight wheel hub bearings will increase the friction force of the wheel rotation; too loose, the wheel will easily tilt or shake during driving, increasing the friction force between the wheel and the ground, leading to a decrease in the car's coasting performance. It is recommended that owners regularly go to professional repair shops for inspection and adjustment of the tightness of the wheel hub to maintain the best working condition of the wheel rim.
Correct front-wheel alignment can ensure that the car is in pure rotation while driving and can ensure the stability and lightness of the car while driving. If the front-wheel alignment is incorrect, it will cause the car to roll while sliding during driving, not only increasing the wear of the wheels but also increasing the friction resistance between the car and the ground, leading to a deterioration in coasting performance and increased fuel consumption. Nowadays, large automobile specialized repair shops should all offer four-wheel alignment services. Owners can conveniently do the four-wheel alignment project while doing other maintenance or inspections on a daily basis. The time spent is relatively economical, and more importantly, safety is improved.
The tire pressure should also be adjusted in real-time according to changes in weather and road conditions. When the temperature is higher, the pressure can be adjusted lower to prevent blowouts.
Braking System - Ensure Sensitivity
The quality of braking technical performance directly relates to whether the car's technical performance and work reliability, as well as driving safety, can be achieved. Good braking performance is a reliable guarantee for safe driving and can also improve the car's work efficiency. However, once the parts in the brake system are improperly adjusted or show signs of excessive wear, it leads to a decrease in the sensitivity of the car's braking system, resulting in failure or deviation. If such a situation has occurred, the owner should immediately go to the repair shop to adjust the braking system and replace the worn-out brake pads. It’s best to check the brakes before every trip to ensure they're functioning normally.
In addition to separately maintaining these systems, you can also clean and apply protective coatings to the entire chassis to slow down the aging and rusting of the chassis, providing some resistance against external impacts.
