The correct way to cross the rubber deceleration belt is that many schools, hospitals, communities and narrow roads are equipped with rubber deceleration belts, which protrude from the ground to a certain height, so that vehicles have to slow down While some drivers often press the rubber deceleration belt on one side or pass directly without deceleration for convenience In fact, although the rubber deceleration belt without any place in the city looks insignificant, it does have a certain impact on the vehicle loss, especially the loss of the suspension system How can we correctly pass the rubber deceleration belt?
1. Two wheel pass
When the two wheels of the vehicle pass through the rubber corner guard, the left and right suspension balance the force on the vehicle suspension system, resist the impact force, and transfer the impact force to the vehicle body for mitigation Although the vibration of the car body is large at this time, it can effectively reduce the possibility of dislocation But even in this case, if you do not slow down, it will still accelerate the wear of the tread rubber, cause the car to deviate, and seriously damage the tires, wheel hubs, chassis suspension, etc Moreover, for some models with low chassis, the vehicles passing through the rubber deceleration belt at high speed are easy to support the bottom
2. Single wheel passing
From the perspective of the driver's feeling, when one side of the wheel passes through the rubber deceleration belt, the impact force felt in the car is less than the vibration caused by the two sides of the wheel rolling through the rubber deceleration belt at the same time When one side wheel passes through the rubber deceleration belt, the impact force is completely borne by the suspension on one side, which greatly increases the impact on the single side suspension. Such operation for a long time will have an impact on the single side suspension, resulting in suspension dislocation, deformation and even wheel positioning deviation If the wheel deviates due to this, the four-wheel alignment should be carried out in time to reduce tire wear and increase driving safety
3. Vertical passage
Vertical passing means that the car passes straight through the rubber deceleration belt In this case, the car feels bumpy and bouncing The left and right wheels contract at the same time. The force from the ground is shared by the springs and shock absorbers of the two wheels in half. The force is uniform and is not affected by the independent or dependent suspension form Although the vibration of the car body is large at this time, it can effectively reduce the damage to the suspension
4. Pass sideways
When the car tilts slightly and passes through the rubber deceleration belt, I feel that the body does not bounce so much, but the swing range is larger It is also easy to cause uneven stress on the left and right suspensions and damage the suspension system From the structure of the car body and suspension, the action of the car passing the rubber deceleration belt is the pressure movement of the wheels (including suspension) between the ground and the car body If you cross the rubber deceleration belt obliquely, the spring, shock absorber and the whole body (frame) will actually have greater damage consumption In addition to the suspension and tires, the car body also absorbs certain vibrations, so the vibrations transmitted to the human body are slowed down
