How Different Types of Suspension System Works? Explained in Details Suspension System: The automobile vehicle's frame and body are mounted on the front and rear axle not directly but through some form of springs and shock absorbers. This is done to damp to road shocks transmitted parts which perform this function are collectively called a suspension system. Thus, the suspension system includes springs, shock absorbers, and mountings. The suspension system of a motor vehicle is divided into the rear end suspension and front end suspension. Types of Suspension System: Independent suspension: In this type of suspension, each front wheel is independently supported by a coil, torsion bar, or leaf spring. Most of the passenger cars now use the independent front suspension in which the coil spring system is the most common. Types of Independent suspension: 1. Macpherson Strut Suspension 2. Double Wishbone Suspension 3. Multilink Suspension 4. Trailing Arm Suspension Non-Independent or Rigid axle suspension: This type of suspension was universally used before the introduction of independent front wheel suspension. It may use either two longitudinal leaf springs, as shown in the figure, or on transverse springs, usually in conjunction with shock absorbers. These assemblies are mounted similar to rear leaf spring suspensions. Types of Non-Independent or Rigid axle suspension: 1. Solid Axle Leaf Spring Suspension 2. Solid Axle Coil Spring Other Suspension Types: 1. Air Suspension 2. Hydro Elastic Suspension
