1. The body leans through the speed bump
Many car owners think that when the car is leaning through the speed bump, the body bounces not so much, so the damage will be relatively small. In fact, when the vehicle body passes obliquely, the swing range of the vehicle body is larger, and it is easier to cause uneven force on the left and right suspension and damage the suspension system. For the entire spring, shock absorber, and the entire body (frame), greater damage and consumption will occur.
2. The body passes through the speed bump on one side
Passing speed bumps unilaterally is the choice of many car owners. Many car owners have a habit of seeing that the length of the speed bump does not cover the whole day, and there is still room on the left and right sides. Without speed bumps, they will use one-sided two-wheeled method to roll over the speed bump. To
They think this can reduce the damage on one side. In fact, they are right, it is true. However, one problem is ignored. The impact force is borne by one side. After a long time, the suspension is prone to dislocation and deformation, and problems with four-wheel alignment may occur! The tires will wear out too! If you did this before, it is recommended to do four-wheel alignment in time! So this approach is not correct.
3. Pass the speed bump quickly
Of course, there are also car owners who ignore the existence of speed bumps, especially cars with a relatively high chassis, such as SUVs, which usually choose to pass quickly. This will have a great impact on the vehicle suspension. After the suspension is contracted, the downward rebound will be greater. It's big, it will be damaged for a long time like this. If the speed bump is high and the vehicle speed is fast, the impact force on the suspension of the vehicle will be too large, and the phenomenon of "knocking" the chassis will also occur. To
Fortunately, the speed belt is complete. If the speed belt is damaged, only the nails to fix the speed belt are left. When passing quickly, it may get stuck into the tire and cause a puncture. To
4. Step on the brake and pass the speed bump
When the brakes decelerate, the center of gravity of the body will move forward. If you step on the brakes and pass the deceleration belt, then all the body weight will be pressed on the front wheels, which will cause the vehicle's front shock absorber to be compressed again in the compressed state, which will not only damage the shock absorber It's very large, and it can't alleviate the vibration.
How to pass the speed bump correctly?
1. Reduce the speed in advance
For cast steel deceleration belts, observe the road conditions ahead, especially when the vehicle has reached the speed limit. Reduce the speed. After the deceleration belt is found, the speed will be braked linearly, and the speed will be reduced in advance. If the vehicle speed is not lowered, the tires and suspension will be seriously injured, and the wheels will be damaged in severe cases.
2. Both wheels pass the speed bump at the same time
Keep the two wheels passing the speed bump together, and the left and right wheels contact the speed bump at the same time to balance the impact on both tires. Make the suspension system on the left and right sides balance the force and reduce the damage to the greatest extent. Sitting in the car may be a little bit more upside-down. But the car may be reduced from a relatively large damage to a very small one at a time, which is a relatively good balance.
3. Reasonably use the brake throttle
The brakes should be released before the wheels are ready to pass the deceleration belt, so that the center of the vehicle will move back, releasing the load of the front shock absorber, so that the front shock absorber will have a good condition to meet the impact of the deceleration belt. When the front wheel passes the speed bump, that is, when the speed bump is located in the middle of the vehicle, do not rush forward with oil. Wait for the rear wheels to rely on the vehicle's forward inertia to pass the speed bump, and then slowly linearly give the throttle to continue forward.
