Nitro Shock Absorbers

A shock absorber is basically a hydraulic damping mechanism for controlling spring vibrations. It controls spring movements in both directions: when the spring is compressed and when it is extended, the amount of resistance needed in each direction is determined by the type of vehicle, the type of suspension, the location of the shock absorber in the suspension system and the position in which it is mounted. Shock absorbers are a critical product that determines an automobile's character not only by improving ride quality but also by functioning to control the attitude and stability of the automobile body.

Principle Of Operation

The damping mechanism of a shock absorber is viscous damping. Viscosity is the property of a fluid by virtue of which it offers resistance to the motion of one layer over the adjacent on. The main components of a viscous damper are cylinder, piston and viscous fluid. There is a clearance between the cylinder walls and the piston. More the clearance more will be the velocity of the piston in the viscous fluid and it will offer less value of viscous damping coefficient. The basic system is shown below. The damping force is opposite to the direction of velocity.

I-CLEARNCE, II-PISTON, III-VISCOUS FLUID

The damping resistance depends on the pressure difference on the both sides of the piston in the viscous medium. The figure shown below shows the example of free vibrations with viscous damping. The equation of motion for the system can be written as mx + cx +kx = 0.

Advantages Of Nitro Shocks

Instantaneous response :

1.Because the high pressure eliminates aeration (foaming), action is always is immediate.

2.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.
