Nitro Shock Absorbers
Nitro Shock Absorbers.docx (Size: 171.92 KB / Downloads: 62) Definition 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. Construction The dampers rely, as their name suggests, on the friction within a stack of disks, clamped tightly together with a spring and clamp bolt. André Hartford pattern The friction disk material was usually a wooden disk between the two faces of the steel arms. As for the development of the clutch and brake shoes, the development of these friction materials was in its infancy. Treated leather had been used for clutches and although it offered good friction behaviour, it was prone to stiction when first moving off and also failed when overheated. Asbestos-based friction materials were sometimes used for racing, in an attempt to keep dampers working correctly even when overheating. The damping force of a friction shock absorber is adjusted with the central pivot and clamping bolt. A star-shaped spring applies a force to the stack of disks. The damping force is roughly proportional to this force and the clamping nut is provided with a pointer arm to indicate the approximate setting. |
