Types of Vehicle Shock Absorbers (Car)

Spread the love

One of the most important parts of any car is the shock absorbers, whose main function is to lower the pressure that the vehicle itself exerts on itself and on the wheels of the car. Shock absorbers, therefore, reduce the damage that impacts during driving have on the vehicle itself, in addition to allowing a better grip of the tires on the road.

Types of vehicle shock absorbers

However, the types of shock absorbers that can be found in cars are very varied. Although most of them have common elements, you can also find specific shock absorbers for private cars that are out of the ordinary. We will tell you what are the main types of vehicle shock absorbers that you can find on the market.

Hydraulic shock absorbers for cars

Hydraulic shock absorbers for cars are very simple and are mainly characterized by using fluids to allow the damping to take place. The most common hydraulic shock absorbers are those that use a cylinder that contains a piston with various holes in it. This allows the fluid, which is usually a specific type of oil for this purpose, to circulate through the holes, allowing the pressure to be adjusted.

On the other hand, you can also find hydraulic shock absorbers with valves. They are more efficient than hydraulic shock absorbers with holes, as they have valves on the pistons, allowing oil to flow through them when pressure is applied. This results in smoother and more pleasant driving experience.

Tube shock absorbers for car

It is a type of shock absorbers that, in addition to oil fluids, can also use gas in the damping. In the case of double-tube shock absorbers, these are made up of two chambers of different sizes (large and small), as well as the corresponding pistons, cylinders and valves. Through its mechanism, located mainly in the large chamber, the oil passes from one chamber to another. There are several types of this shock absorber depending on whether they use only oil or oil and gas, being the pressurized ones that only have the oil fluid and the non-pressurized ones that have oil and gas. They are perhaps the most widely used shock absorbers today in most vehicles on the road.

In addition to double-tube shock absorbers, you can also find monotube shock absorbers, which also have two chambers but whose sizes can vary much more. In this case, it would be a system that combines both gas and oil to perform damping.

Adjustable dampers

As its name suggests, these are shock absorbers that can be easily adjusted, which also allows the damping to be adapted to the type of driving and terrain to be travelled. On the one hand, there are those known as hardness adjustable dampers. These shock absorbers include a small washer that allows the oil passage that is allowed through the holes of the shock absorber to be adjusted more or less. In this way, you can have more or less pressure depending on the needs of each case.

On the other hand, the adjustable suspension dampers use a similar system, but they are characterized by a more millimetric adjustment of the distance to be achieved between the road and the highest part of the vehicle, which would include both the bodywork and the rest of the elements of this part of the car.

Other types of shock absorbers

Although the ones mentioned above are the most common and most used shock absorbers in today’s cars, it is important to note that shock absorbers with other different typologies can also be found.

A good example is the so-called rheological shock absorbers, whose main characteristic element is the incorporation of small metallic compounds with which greater resistance in damping is achieved since they imply a more compact force.

On the other hand, it is also worth mentioning the selective frequency dampers. In this case, the shock absorbers have a valve that reacts by closing when it receives a certain pressure and that marks the difference between the two piston tubes.
