About the maintenance and fuel consumption of the car chassis
1. The front pulley is properly adjusted. Inaccurate front beam will increase the rolling resistance of the vehicle and increase fuel consumption. Check the forebundle value regularly and compare it with the normal value. If the value is different, adjust it.
2. Wheel bearing is well lubricated and properly adjusted. Poor wheel grease and improper adjustment of bearing clearance will increase the driving resistance.
3. Pay attention to the changes of front and rear axle and frame. The front and rear axle and frame displacement or bending deformation, so that the body can not maintain vertical or horizontal, the car is driving to a side of the steering, the tire and the ground sliding friction, thus increasing the driving resistance, so that the fuel consumption rises significantly.
4. Pay attention to whether the leaf spring is damaged. Leaf spring damage to the car driving balance is poor, increased driving resistance, fuel consumption is also rising.
5, brake clearance adjustment is appropriate. Brake clearance is too small, resistance increases, to open the throttle to drive, will increase oil consumption; If the clearance is too large, the braking will not work. It also plays an important role in the gliding performance of the car to adjust the brake clearance and avoid the brake lag and the clearance is too large or too small.
6. Pay attention to the working condition of the clutch. The clutch working condition is poor, in the process of transferring torque, there will be "shaking", "skid", "separation is not complete" and other phenomena, so that the transmission efficiency is reduced, the fuel consumption is increased.
7. Pay attention to whether the tire pressure is normal. The tyre type should be the same. According to statistics, the tire pressure is 30% lower than the specified value, the tire service life is 33% shorter, the fuel consumption increases 6%.
