We usually drive on the road. Except for some signs, we encounter more speed bumps. Maybe some friends don't pay much attention to it. Sometimes when passing speed bumps, it doesn't matter if you fumble. However, this kind of thing cannot be ignored, not only destroying the car but also hurting money! The following is an introduction to the specific methods of speed bumps:
1, two-wheel pass
When the two wheels of a car pass through the rubber speed bumps, for the vehicle suspension system, the left and right suspension are balanced to resist the impact force and transmit the impact force to the body to slow down. Although the vibration of the body is large at this time, it can effectively reduce the possibility of misalignment. But even in this case, if you don't slow down, it will accelerate the wear of the tread rubber, causing the car to deviate, etc., and seriously damage the tires, wheels, chassis suspension, etc. And for some models with low chassis, it is easy to support the bottom of the vehicle through the rubber speed bump at high speed.
2, a single pass
From the perspective of the driver and passengers, when one wheel passes through the rubber speed bump, the impact felt in the car is less than the vibration caused by the two wheels simultaneously rolling through the rubber speed bump. When a single-sided wheel rolls over the rubber deceleration belt, the impact force is completely borne by the suspension on one side, which greatly increases the impact on the single-sided suspension. This operation for a long time will affect the single-sided suspension, resulting in suspension misalignment, Deformation can even cause deviations in wheel alignment. If the wheels deviate due to this, four-wheel alignment should be done in time to reduce tire wear and increase driving safety.
Passing vertically means that the car is aligned with the rubber speed bump and passes straightly. In this case, the bumpy and bouncing feeling of the car is relatively large. The left and right wheels contract at the same time, and the force from the ground is shared by the springs and shock absorbers of the two wheels. The force is evenly received and is not affected by independent or non-independent suspension. Although the vibration of the body is large at this time, it can effectively reduce the damage to the suspension.
4. Pass diagonally
When the car leans slightly through the rubber speed bump, it feels that the body does not bounce so much, but the swing is larger. This situation is also more likely to cause uneven forces on the left and right suspensions and damage the suspension system. From the perspective of the structure of the car body and suspension, the movement of the car through the rubber speed bump is the pressure movement of the wheels (including the suspension) between the ground and the body. Leaving the rubber deceleration belt obliquely will actually cause greater damage to the springs, shock absorbers and the entire body (frame). Because in addition to the suspension and tires, the body also absorbs a certain amount of vibration, so that the vibration transmitted to the human body is slowed down.
Although speed bumps can pit people and cars, it is also a product derived to reduce the occurrence of traffic accidents. When vehicles are forced to pass through these accident-prone sections, they need to reduce their speed to ensure that the driving is safe. As car owners, in order to avoid being trapped, remember to slow down before passing the speed bump and use the correct method to pass the speed bump!
