For a smooth and comfortable ride the disturbing forces should be eliminated or reduced considerably by using some devices. Shock absorbers are such devices which isolate the vibrations by absorbing some disturbing energy themselves. Of the many types telescopic shocks are widely used which has got the draw back that the flow of oil in the cylinder can cause foam of oil and air to form.
These limit the optimum throughout of the flow in the valves. Gas shocks represent an advance over traditional shocks. Nitrogen filled gas shock absorbers are the results of years of extensive research and development with top flight shock design engineers.
They are designed for both lowered and stock vehicles to provide shock absorbers that would out perform anything on the market today. Nitro shock absorbers are high quality, nitrogen filled shocks designed and gas charged specifically for each vehicle application. The addition of nitrogen under pressure limits the foaming effect and increases efficiency.
SHOK ABSORBER ACTION
Shock absorbers develop control or resistance by forcing fluid through restricted passages. A cross-sectional view of a typical shock absorber is shown below. Its main components and working is also given below.
The upper mounting is attached to a piston rod. The piston rod is attached to a piston and rebound valve assembly. A rebound chamber is located above the piston and a compression chamber below the piston. These chambers are full of hydraulic fluid. A compression intake valve is positioned in the bottom of the cylinder and connected hydraulically to a reserve chamber also full of hydraulic fluid. The lower mounting is attached to the cylinder tube in which the piston operates.
During compression, the movement of the shock absorber causes the piston to move downward with respect to the cylinder tube, transferring fluid from the compression chamber to the rebound chamber. This is accomplished by fluid moving through the outer piston hole and unseating the piston intake valve.
During rebound, the pressure in the compression chamber falls below that of the reserve chamber. As a result, the compression valve will unseat and allow fluid to flow from the reserve chamber into the compression chamber. At the same time, fluid in the rebound chamber will be transferred into the compression chamber through the inner piston holes and the rebound valve.
ADVANTAGES OF NITRO SHOCKS
Instantaneous response :
Because the high pressure eliminates aeration (foaming), action is always is immediate.
The low mass of gas and the single tube further improves response time.
Better fade resistance :
Since there is no outer tube, cooling is much better which gives a drastic reduction in fade. Thus more consistent handling and control.
Better durability :
Single-tube construction also allows for a larger internal working area, reducing stress and fatigue for better durability.
De Carbon’s monodisc valving system features a single moving part that drastically reduces inertia and friction, to improve durability and performance.
Better cooling of the mono tube design results in lower operating temperatures and thus longer life.
No need for re-adjustment:
The viscosity of hydraulic fluid changes as temperature changes. This may because of climate, season (summer/winter) or heavy duty (motorway cruising). The high pressure gas compensates immediately and automatically for changes in viscosity.
In the current scenario of automobile industry the need for vehicles which provides smooth and comfort ride is growing. Nitro shock absorbers are designed to be ultimate in performance and comfort. In a country like ours whose roads are not up to world standards the need for automotive components like nitro shocks are necessary. It goes without saying that if the right choice is made the improvements in vehicles ride and handling can be shocking.
