Damping system: operating principle, malfunctions, maintenance and replacement
The damping system includes components and assemblies designed to absorb vibrations when driving on uneven roads, cushion the hits, and also prevent the car body from swaying when accelerating and slowing down. They keep the car body at the required level above the ground, and ensure comfortable ride. They provide driving safety and vehicle steerability.
Main types
By the type of shock absorbers:
- With mono-tube shock absorbers. Their design has a working cylinder which is the body of the component at the same time.
- With twin-tube shock absorbers. Their working cylinder is placed inside the housing. There is a gap between their walls.
By the type of suspension elements:
- With leaf springs. They comprise several steel sheets of different lengths bound with clamps.
- With coil springs. They are made of wires with constant or variable cross-section.
- With torsion bars. They are made as rods which absorb vibrations by being twisted.
- Pneumatic (air). It allows adjusting the ride height. Air bellows can be used together with springs or shock absorbers, or as independent elements.
- Hydropneumatic. In these damping systems, the springing elements are hydropneumatic spheres filled with gas and liquid.
By adjustability of the dampling properties:
- Non-adjustable. Characteristics of the springs and shock absorbers are factory set.
- Adjustable. It allows to adjust the stiffness of shock absorbers, spring preload and ride height.
- Adaptive. The intensity of damping is changed in accordance with road conditions. That becomes possible due to the use of springs made of wire with variable stiffness and shock absorbers with solenoid valves or special fluid.
Main components and operation features of the damping system
Main elements of the system are shock absorbers and springs. They are attached to the car body and suspension components through bushes and, sometimes, mounts or spring caps (seats). Shock absorber rod is fitted with a bump stop and a boot. The former is designed to limit the rod travel when the shock absorber is fully compressed. The latter protects the assembly from negative environmental impacts. Springs can be a part of the strut or installed separately.
Most common malfunctions
- Springs sag, which is caused by failure to observe the recommended replacement intervals, constant overloading of the vehicle and the use of non-fitting components.
- Coils of the parts can get damaged, which can be the result of a collision, exposure to moisture and dirt.
- Shock absorbers lose tightness due to worn-out or damaged seals.
- Rusty caps (seats) of the springs in the damping system are the result of frequent driving on muddy roads, rapid ambient temperature changes, exposure to road chemicals.
Proven ways to extend the service life of the system
Avoid aggressive driving, slow down before obstacles and while cornering. This will reduce the load on the damping system components. Check the boots regularly: if they are torn, replace them. Clean the components of dirt: this will help to prevent corrosion.
What you should know about repairing the damping system
Damping system components can’t be repaired. If they become out of order, they have to be replaced. It is very important to install new spare parts in due time. Otherwise, components of the suspension may wear prematurely.
