The suspension system of heavy cars is very similar to the suspension system of light cars, but the components of each system are different, which generally affects the comfort of the passengers, and a large part of the good driving experience with a car is the same. The system is connected As mentioned, the components of heavy car suspension system are different, but both of them ultimately have the same task, but this difference has a significant impact on its working process. The difference in the suspension system in different cars is more than anything due to the connection of the wheels on the same axle. In any way, this communication is done with the aim of optimizing the movement of the car on the road surface. This optimization leads to the smooth movement of the car and the control of the pressures caused by the movement.
In most cases, the suspension system of heavy machines is of hydraulic type. Heavy cars put more pressure on the roads due to their weight, and then the road puts more pressure on them. If the car's suspension system cannot perform its duties well, the pressure from the road on the car will also affect the drivers. The most important thing that the suspension system does is to provide a comfortable ride for the passengers and of course to protect the main components of the car against the pressures from the road. The suspension system, managing the pressure from the road and the pressure on the road, apart from protecting the passengers and car parts, also affects the acceleration, braking and longitudinal movement of the car.
Basically, the weight of the car is measured once before installing the suspension system and again after installing the suspension system. The weight measured in these two cases should be proportional to each other. This fit is obtained based on several factors such as the shock absorber coefficient, the angle of the spring and body, and the stiffness of the spring. If this fit is properly observed, the car suspension system can bear the weight of the car, absorb shocks, convert the pressure of damage into vibration, maintain the steering wheel position, correct the angle of the wheels, create a suitable contact surface between the wheels and the road, increase the car's steering and protect The car provides a wonderful driving experience for the passengers against the pressure from the road.
Suspension systems consist of seven parts. These components include:
• Sibak
• Strat • Desire for balance • shock absorber, springs • Bush • According to Of course, it should be noted that in different heavy machines, these components vary according to the weight and size of the chassis. Today, many heavy machines use suspension and hydraulic brake systems. One of the most important differences between air and hydraulic suspension systems is that the controller in the air suspension system is air, but in the hydraulic suspension system, a controlling fluid is pumped by a cylinder in proportion to the applied pressure, but still air suspension systems have their fans. has it Advantages of air suspension systems: One of the most important advantages of using airbags and removing traditional shock absorbers is that it reduces the weight of the chassis and increases the efficiency of the tanker trailer. With the progress of these dampers, we can see that today they can receive information from special sensors and adjust the damping level of the springs in a few milliseconds completely automatically. This issue can increase the safety and comfort of the driver of heavy vehicles. By using these controllers, there is no need to adjust manually every time you get into heavy vehicles, and you can adjust the suspension system of heavy vehicles automatically. Other advantages of these systems include less tire wear and reduced wear and tear of other parts, less driver fatigue and reduced risk of injury, saving extra car weight and reducing the need to repair various car parts.
The following are among the most common problems of car suspension systems:
- steering wheel slip - Failure to properly control the car - Improper angle of the wheels - Appearance changes in the car It can be said that the shock absorber is a consumable part in the suspension system, because if the pressure applied to the road is more than the power of the axle, the first damage will come to the shock absorber, so you need to pay more attention to the shock absorbers. If your car doesn't turn smoothly, if it's hard to steer, your car's suspension system is squeaking, your suspension system is lying on the ground, or you're going up and down on bumps, the problem is with your car. Installing Sibek in the suspension system of heavy cars is a bit difficult and specialized; But, in general, Sibak is a replaceable part. Sibaks control and manage a lot of pressure by making it possible for the wheels to rotate and restrain the fluctuations caused by the up and down of the car, and for this reason, their health is important in the useful operation of the car. Note that the balance shaft of the suspension system of heavy vehicles may also wear out. If this part of the suspension system, which connects the wheel to the steering wheel, wears out, the car's ride will suffer and not only the shape of the wheels will change, but the car's steering will also be completely impaired. If your steering wheel is loose or rattling, your wheels go out of control during acceleration, or you have extra movement at high speeds, your car's suspension balance shaft is probably wrong. Note that replacing and repairing suspension system parts of heavy and light cars is a specialized matter.
