Understanding the Hydraulic Suspension System

A suspension system is one of the most vital parts that are present in an automobile, most people don’t recognize it by its name, it is connected to the wheel which generally looks like a spring. The spring helps in the shock absorbing process which helps us experience a smooth ride since no road is perfectly paved the irregularities on the roads (especially in India) results in generating different forces which act on the wheel unnecessarily. These forces are controlled by the suspension.

Today automobile designers are more focused on achieving a better driving experience by improvising the suspension system. Several types of suspension systems are now available in the automobile industry, one of them being the hydraulic suspension. It is interesting to understand the working of a hydraulic suspension system.

The first type of hydraulic suspension was created by Citroen and designed by Paul Mages. The purpose of then creating the hydraulic suspension was to attach it to cars and trucks. But in this modern age, this system has been introduced to various military vehicles and tanks.

Working Of Hydraulic Suspension System

The hydraulic suspension consists of a hydraulic liquid which is a type of oil that is put inside a tube and attached to the spring also a compressed gas is present in the inner chambers of the tube of the suspension system, a set of such hydraulic springs are attached to each other in a certain pattern. This system is then attached to the wheel.

The suspension absorbs the shock generated by the wheels and pumps in the hydraulic liquid, i.e, whenever the wheel moves through an irregular road the wheel pumps in the hydraulic liquid inside the tube forcing it inside, while the fluid collides with the compressed gas, the gas forces it back to its original state, while this phenomenon generates an opposition force, this force allows the spring of the suspension system to control the wheel. Allowing the wheel to have a tighter and better grip on the road.


Advantages of hydraulic suspension

  • The hydraulic suspension generally provides a better driving experience as compared to other suspension systems such as steel springs.
  • Its reaction time is faster than other systems, resulting in faster results hence preventing the chances of any road accidents.
  • There are independent dampers present which ensures faster reaction time.
  • Hydraulic suspension systems are adjustable, the driver of the vehicle can customize his or her own system for shock absorbance.

Disadvantages of hydraulic Suspension

  • Hydraulic systems are costly to produce and maintain, the cost for its maintenance would be too high for common people.
  • People have now various and better options for suspensions and vehicles to choose from at a reasonable price.
  • Possibility of fluid leakage is high and the cost for its repair work will be automatically high.
  • Maintenance for the hydraulic suspension system is not easily available at every car repair shop.

Although hydraulic suspensions are now being introduced in the automobile world for its customers, with all its benefits it’s still difficult to reduce the cost of such an excellent suspension system. That is why it is still not much popular among the common people, but when the day comes where efficiency in performance meets cost-effectiveness that would be the day when the hydraulic suspension would be used worldwide.
