Almost all the vehicles have soft spring at front suspension and stiffer spring at rear suspension. The following two common question arises, Why not use both with same stiffness? and  Why do we need a soft spring at front and not at rear?  The answer to the above first question is that if the springs are made out of same stiffness then the car may experience a jumping effect due to weight transfer of the vehicle during accleration of when the car travel over uneven road. Now as we know when we use soft spring, the wheels have more traction or contact with the ground. Thus, the description itself answers the question i.e by using soft spring at front will give more contact with the road hence when a car jumps or travels an uneven surface it will help the car to steer well and keep the car in control. Ofcourse using soft springs at the rear will provide more traction to the rear wheel driving car but car handling is a more critical part then traction. So, it is always pre

Magnetic Suspension or magnetic ride control is a type of suspension system where the shock absorbers reacts to the road and adjusts much faster than regular absorbers. Magnetic suspension can adapt to uneven road surfaces several hundred times per second, in fact it takes only a few milliseconds to adjust any one of the shock absorbers. Magnetic suspension is described as the fastest reacting suspension in the world as sensors monitor the road surface up to 1000 times per second and an ECU can make variations within a few milliseconds resulting in the possibility of multiple damping variations being made in a second.  Magnetic ride control uses a system known as magneto rheological technology for suspension damping. Each absorber is filled with a polymer liquid containing many small magnetic particles . An electrical charge is sent to the liquid in the absorber which immediately changes the position of the particles in the liquid and its viscosity. The viscosity of the pol

The roads are filled with irregularities and uneven surface. Vehicle moving over such terrain thus experiences vibrations due to the force transmitted because of the uneven surface. The vibrations in the vehicle arising due to road irregularities are absorbed by the suspension system.  For a Double Wishbone system the force gets transmitted from the wheels to the Knuckle then to the lower a arm and finally to the shock absorber where it gets damped out. Thus, the suspension system helps to provide a smooth and comfortable ride to the passengers. When a vehicle hits a bump in the road it causes the wheel to move up and down perpendicular to the road surface. The magnitude, of course, depends on whether the wheel is striking a giant bump or a tiny speck. Either way, the car wheel experiences a   vertical acceleration   as it passes over an imperfection. Without an intervening structure, all of wheel's vertical energy is transferred to the frame. In such a situat
