Shock absorbers

SHOCK ABSORBER CONSTRUCTION Bore Size Bore size is the diameter of the piston and the inside of the pressure tube. Generally, the larger the unit, the higher the potential control levels because of the larger piston displacements and pressure areas. The larger the piston area, the lower the internal operating pressures and temperatures. This provides […]

SHOCK ABSORBER DESIGN There are two basic shock absorber designs in use today: the two-tube design and the mono-tube design. The conventional shock absorber is illustrated in Fig. 2. Notice that it has two tubes. The inner tube is known as the pressure or working cylinder, while the outer tube is known as the reserve

WHAT SHOCK ABSORBERS DO Let’s start our discussion of shock absorbers with one very important point: Despite what many people think, conventional shock absorbers do not support vehicle weight. Instead, the primary purpose of the shock absorber is to control spring and suspension movement. Shock absorbers are basically oil pumps. As shown in Fig. 1,
