It uses a simple beam that attaches to the chassis through links and springs/dampers. So in the turn, camber of that wheel is inside turn is zero or negative (useful) and outside turn is negative (useful). This creates a small tire/road friction resistance that in turn translates into feedback from the road. Axles are used to connect the left and right wheels at the front or rear of the vehicle.

In this design, a damper is usually installed inside the coil spring. 0000010148 00000 n In order to absorb shocks, manufacturers provide a spring and a hydraulic damper between each wishbone and car frame/body. (The mount points on the chassis and wishbones/links form the “inboard” side of the suspension, and provide their own contribution to the overall geometry of the suspension.). The axle shafts are housed inside of axle tubes which provide protection from the environment and the strength needed to support a vehicle chassis. Bearings (Orange) are inserted into the hub (Red) and it is slid over the spindle and held in place by a retaining nut. This system is also known as the parallelogram type suspension system. The differential accepts power through an input shaft, and transfers it through the axle shafts to the wheels. McPherson Strut: This design uses a special unit consisting of a spring and shock-absorber. 3. B. Mac Pherson Front Suspension In This case , normally, positive camber angle is very low and The closed end of the top wishbone connects to the top of the stub axle by a ball joint. 1.Coil Springs type I: This design uses coil springs which provides springing action to the suspension. 0000007171 00000 n This Web site and the attached documents are provided “as is” without warranty of any kind, either express or implied, including, but not limited to, the implied warranties of fitness for a particular purpose. 0000240037 00000 n 0000007837 00000 n In this system, the wheels connect to the frame in such a way that the movement of one wheel is not dependent on the other.

The upright or knuckle attaches the wheel, brake rotor, hub, brake caliper and steering arm to the vehicle as shown in diagram KU1 below. 0 This design uses a steel rod known as the torsion bar. Double Wishbone Suspension System consists of two lateral control arms (upper arm and lower arm) usually of unequal length along with a coil over spring and shock absorber. Diagram KU2 shows an example of an independent wishbone suspension for a driven wheel. It acts as a spring to hold the upper and lower arms parallel under load. The kinematic diagram, vector loop and position analysis for the suspension is shown below. This would normally have a detrimental effect on turning because the rear wheels would push at the same speed in a straight line while the front wheels are trying to turn. 6.
