Hydraulic Suspension System Guide

The suspension system of a car is one of its most critical components. Most people are not too familiar with this part. It resembles a spring and connects to the wheel. This spring helps with the shock-absorbing process to provide a smooth ride. The roads in Las Vegas, Nevada are full of irregularities that generate various forces which unnecessarily act on the wheels. The suspension system controls those forces.

Automobile designers these days are very focused on creating a better driving experience by making improvements to the suspension system. There are several kinds of suspension systems that are available these days to the automobile industry, with the hydraulic suspension being one of them. It is important to understand how the hydraulic suspension system works.

The suspension system of every utility vehicle, truck, and car is designed to do three main things:

Provide the vehicle with support
Absorb shocks and bumps
Allows vehicles to turn based on the driver’s steering input

Suspension System Elements:


Let’s talk about some of the main points of both of them.

    1. Springs

Springs are very resilient parts and act as energy reservoirs. They store up the energy from the sudden force that occurs when a ditch or bump is encountered by a vehicle. The energy is subsequently released and with the damper’s action, this energy gets converted in heat and bouncing is avoided. The suspension system’s spring then quickly absorb the road shocks and slowly return back into the original position.

Types Of Springs:

Rubber spring
Gas and air spring
Torsion bars
Coil spring
Leaf spring

  1. Damper

Dampers reduce the carriage unit’s tendency to continue “bouncing” up and down on the springs.

The oscillation caused by road shock is reasonably restricted by the damper.

Kinds of Dampers

Rocking level damper
Telescopic damper

Let’s talk about some of the main points of both of them.

The hydraulic suspension system is comprised of a hydraulic liquid that is a kind of oil that is placed inside of a tube and then attached to a spring. There is a compressed gas inside the tube’s inner chamber of the suspension system. A set of these hydraulic springs are attached to one another in a specific pattern. The system is attached then to the wheel.

The suspension system absorbs the shock that is generated by the pumps within the hydraulic liquid and the wheels. So whenever the wheel is moving across an irregular road, the hydraulic liquid inside of the tube is pumped by the wheel and forces it inside. The fluid then collides with compressed gas, and the gas is forced back into its original state. An opposite force is generated by this phenomenon, and this force is what allows the suspension system’s spring to control the wheel. This makes it possible for the wheel to have a better and tighter grip on the road.

Hydraulic suspension advantages

In general, the hydraulic suspension offers an improved driving experience when compared to steel springs and other types of suspension systems.

It has a faster reaction time compared to other systems, which results in faster results and thereby help to prevent road accidents from occurring.

Independent dampers are in place which helps to ensure quick reaction times. Because hydraulic suspension systems can be adjusted, the vehicle’s driver can customize her or his own shock absorbance system.

Hydraulic Suspension Disadvantages

Hydraulic systems are very expensive to manufacture and maintain. For many people, the maintenance costs are also very high.

People these days have better and various options for their suspension systems as well as vehicles to select from at an affordable price.

There is also a high chance of fluid leakage and the cost of repairs is very high as well.

Hydraulic suspension system maintenance is not as readily available at all auto repair shops.


Although there are hydraulic suspension systems being introduced these days into the automotive industry for customers, given all of the benefits it offers, it is still very hard to reduce the costs on this outstanding suspension system. This is why it is still not as popular among ordinary people. However, when cost-effectiveness meets with efficient performance, then that will be when hydraulic suspension systems will start to be used worldwide.
