How to pass the speed bump with less damage to the car?

2022-07-22

I believe we all know what a speed bump is. We can take them literally. They are designed to alert vehicles to slow down and keep pedestrians safe, especially in some neighborhoods, school gates and roads. If the speed bump does not slow down, it will cause great damage to the car.

1. A single wheel passes through the speed bump
Many car owners will choose a single wheel through the speed bump. They think this can reduce damage on one hand. In fact, that's right. This is real. However, you are overlooking a problem. The impact force is borne by one side. For a long time, the suspension is easy to be dislocated and deformed, and there will be problems with the four-wheel alignment! Tires also wear out!

2. Cross the speed bump obliquely
The meaning of oblique passage is also relatively simple, that is, the front of the vehicle is inclined and passed in sequence. This way, you'll feel like it's really not that bumpy! But the force on the left and right sides of the suspension system is uneven! After passing the speed bump, the damage to the spring and damping is even greater! In this way, the body will also withstand the forces generated by the speed bumps! This is really not a good way!

3. The two wheels pass through the speed bump
Currently, the two-wheel pass is undoubtedly by way of speed bumps. Although you will feel a strong vibration, the left and right wheels will contract at the same time! Both the spring and shock absorber are stressed at the same time, independent or non-independent suspension will not be greatly affected! Even in this case, if you don't slow down, it will still accelerate the wear of the tread rubber, causing the vehicle to deviate and seriously damage the tires, wheels, chassis suspension, etc. For some models with lower chassis, vehicles passing through speed bumps at high speed tend to support the bottom.

4. The two wheels pass through the speed bump vertically
A vertical pass is when the vehicle passes directly over the speed bump. In this condition, the car will feel bumpy and bumpy. The left and right wheels contract at the same time, and the force from the ground is shared in half by the springs and shock absorbers of the two wheels. The force is uniform and not affected by the form of independent or non-independent suspension. Although the body vibration is relatively large at this time, it can effectively reduce the damage to the suspension.

In fact, there are many ways to pass speed bumps. The above method of accelerating and decelerating the belt can reduce the damage to the vehicle to a certain extent. The way through the speed bump is a vertical passage for both wheels, which has great strength in terms of chassis, suspension and protection.
