Even on ideal roads there are obstacles, such as speed bumps. And what can we say about our roads, sometimes reminiscent of the lunar surface, dotted with craters! If in your area they managed to carry out patching, then the pits became mounds. How to keep the suspension of your car in good condition in such conditions?
The solution to this problem has two components:
And if the second part is solved simply, for example, with the help of polyurethane products from PolyPro, which will be discussed a little later, then the implementation of the first part requires experience, expert advice and some knowledge of physics.
Let's discuss the basic actions of the driver when driving on dead roads.
Pit: fly by or slow down?
Although the suspension exists in order to muffle the
bumps on uneven pavement, yet this design is designed for a certain load. How not to kill the suspension: not to exceed the load limits and prevent impacts on the body that destroy other nodes?
Recall Newton's second law, according to which force (including the impact force) is proportional to mass and acceleration. The mass of the car at the moment of movement does not change, and the acceleration can be reduced, then the impact force will decrease proportionally. So, physics suggests that it is possible to reduce the load on the suspension by overcoming bumps in a longer time, that is, at a lower speed. And "flying" an obstacle at high speed and hitting it, we increase the impact force.
Therefore, professional drivers are advised to slow down in front of the pits up to 3 km / h. This will extend the life of both silent blocks and shock absorbers, and the car as a whole.
Obstacle: hard braking

Obstacle: hard braking
If you understand that you have a deep pothole or puddle in front of you, which there is no way to go around, and moving it can damage the bottom or bumper, then there is also a trick to avoid a strong blow to the suspension.
You need to act in a similar way as in the situation with the "fly" over the pit, but add a twist. Turn the steering wheel sharply so that the wheel entering the hole follows the outer arc, and then straighten the steering wheel. This will cause the wheel to rise due to the spring action of the front anti-roll bar, and the impact force will be less. But on bumps, these actions can lead to the car turning over.
So, competent actions can reduce the load on the suspension on rough roads. And can the replacement of elastic elements with polyurethane ones give peace of mind?
Polyurethane silent blocks from "PoliPro"
It is generally accepted that polyurethane is much stronger than rubber and silicone, and in many ways surpasses rubber by 2-5 times, for example, such as:
Polyurethane elastic elements are durable even in the conditions of killed Ukrainian roads. At the same time, proper car suspension care will help you forget about calls to service stations for a long time.
The PoliPro company offers a full range of polyurethane suspension parts: silent blocks, bushings, as well as elastic elements for other units.
We provide a 1 year written warranty without mileage.
To summarize: gaining experience in driving in extreme conditions, switching to reliable materials in the design of the suspension and taking care of the suspension of the car will help keep the car in excellent condition even in the conditions of our dead roads.
