Knowledge posted: over deceleration in the end brake does not brake?

To slow down, we all know that, but in everyday life, I found that many people are about to brake through the deceleration zone or even through the process. Xiao Bian also specifically consulted professionals on this issue. Not only is it unacceptable, it is also quite ruined!

What do you want to ask me? Then I solemnly told you that the front suspension of the car was such a sin again and again that it was not worth it.

The role of the front suspension

Suspension is an important part of the car, it connects the body and the wheel elastically. Its main function is to transmit all forces and moments acting between the wheel and the body, such as supporting force, braking force and driving force, and to mitigate the impact load transmitted from the uneven road surface to the vehicle body, attenuate the vibration caused thereby, and ensure Crew comfort, reduce cargo and vehicle's own dynamic load.

Consequences of improper braking

When the brakes are applied, the center of gravity of the body moves forward, and the body will lean forward and cause pressure on the front suspension spring. The front suspension spring is greatly compressed, and accordingly, the suspension will be hardened, and the tire vibration is easily transmitted to the vehicle. frame. At this time, through the deceleration belt, the suspension spring has not returned to the initial state, and the buffering function is greatly weakened. In the long run, it will cause great damage to the frame.

The following three methods of over-speed reduction are undesirable

1, high speed over speed

If you take a high-speed over-deceleration belt for a long time, it will cause a greater impact on the vehicle body, and the vehicle will easily support the bottom, especially for some models with low chassis, the risk is even greater.

2, oblique speed over the belt

When the vehicle passes through the deceleration zone vertically, the bumpy and bouncing sense of the car is relatively large, and the car is bouncing off. It feels that the car bouncing is not so big, but the swing amplitude is larger, but the speed-reducing zone is slanted over the spring, the shock absorber and The entire body (frame), will form the uneven force on both sides, resulting in the loss of the vehicle.

3, unilateral tires over deceleration belt

Many owners choose to allow one side of the tire to pass around in the middle of the deceleration zone and only pass the tire on the other side. Actually, this approach is not desirable. If one side leans over the deceleration zone, one side of the front wheel is lost. The quasi-magnitude will obviously exceed the other side, and it will impact tires, suspensions and steering gears. In the long run, the car will be damaged.

Correct way to pass the speed bump

1, before the speed reduction zone, to reduce the speed to 20 km / h, if you do not slow down will accelerate the tread rubber wear, leading to car deviation, etc., will seriously damage the tires, wheels, chassis suspension and so on.

2, double pass

To ensure that the two front wheels press through the deceleration belt at the same time. For the vehicle suspension system, the left and right suspensions balance the force, resist the impact force, and transmit the impact force to the vehicle body to slow down. Although the vibration of the car body is large at this time, the possibility of hurting the car can be minimized.

Xiao Bian sums up so much, everybody's friends of the vast majority of drivers, must keep in mind, protect their own car, do not let it suffer! ! !
