NITRO SHOCK ABSORBERS
nitro shock absorbers.ppt (Size: 115 KB / Downloads: 40) NEED FOR SHOCK ABSORBERS Springs alone cannot provide a satisfactorily smooth ride. Oscillation of spring causes the wheel to rebound, or bounce up and down. Control over the vehicle can be lost. Shock absorbers prevent these spring oscillations. HOW IT WORKS? All shock absorbers use hydraulic fluid to convert the energy of the spring to heat. Consists of two strokes Compression & Rebound WHY GAS FILLED SHOCKS? Rapid movement of the fluid between the chambers cause foaming. Results in a lag because the piston moves through an air pocket which offers resistance. Foaming results in a decrease of damping and a loss of spring control. Pressure increases in front of the piston and drops behind it. All together results in foaming and loss of shock absorber control. GAS FILLED SHOCKS Designed to reduce foaming of the oil. Construction is similar except the double tube, here a dividing piston is used. Two chambers – oil & gas. COMPONENTS Upper and lower mounts. Hydraulic chamber containing hydraulic fluid. Gas chamber containing nitrogen at 25 bars. Dividing piston. How it works? The piston rod is moved into the shock absorber which displaces the oil. This causes the dividing piston to press on the gas chamber, reducing it in size. While returning the gas pressure returns the dividing piston to its initial position. The pressure decrease behind the working piston cannot be high for the gas to exit from the oil column. Thus the gas filled shock absorber operates without foaming. BUMP STROKE When the piston rod is pushed in the floating piston is also forced down slightly increasing pressure in both section. Also the oil below the piston is forced to flow through the piston, this generates the bump damping. REBOUND STROKE When the piston rod is pulled out, the oil between piston and guide is forced to flow through the piston. This resistance generates rebound damping. At the same time part of piston rod will emerge from cylinder and free piston move upwards.
