SPRINGS - Springs are mounted at each wheel and they absorb the road shocks created when the vehicle travels over potholes or speed breakers. Springs are of various types, namely : Leaf springs - Leaf springs are multi-layered steel plates clamped together. Coil springs - Coil springs are made of thick steel wires wound in a spring form - Scorpio Front, Bolero Front Torsion bar - Torsion bar are long steel rods of either circular or square cross section. The springing action is generated by the torsional forces when the torsion bar is twisted - Scorpio 4WD Front SUSPENSION 2. SHOCK ABSORBERS - The springs absorb road shocks. While absorbing the shock , the spring is compressed. However, due to the characteristic of springs, the absorbed shock will be released immediately with the rebound of the spring. Hence , the vehicle will start oscillating after encountering a road irregularity. The purpose of the shock absorber is to absorb the shocks when the spring starts oscillating, thus providing a smooth ride. Shock absorbers are of Hydraulic , double acting type or Gas filled REBOUND VALVE BUMP/REBOUND HYDRAULIC OIL BUMP VALVE SUSPENSION 3. STABILIZER BAR - Stabilizer bars are fitted on the axles to reduce the amount of body roll, when the vehicle is cornered. Stabilizers bar acts as torsion bars and twist , restricting the excessive body roll. SUSPENSION TYPES OF SUSPENSIONS SUSPENSION TYPES CAN BE BROADLY CLASSIFIED AS : RIGID SUSPENSION - In rigid suspension both the wheels in an axle are connected by a rigid beam or a tube. Road irregularities encountered by one wheel is partially passed on to the other wheel SPRING AXLE TYRE SUSPENSION TYPES OF SUSPENSIONS IN...
