How does a double wishbone suspension work?

Double wishbone suspension allows each wheel to act and react independently from the others. The upper and lower control arms have ball joints on both ends to allow movement in multiple directions. Vertical movement is controlled through the shock absorber and coil spring which are mounted on the wishbones.

What is the best suspension geometry?

Caster is one of the most important suspension geometry angles in the world of drifting because of the self-aligning effect it has on the wheels. The ideal thing to do is to run as much positive caster as you can without causing contact between tire and fender.

Is double wishbone expensive?

The only negative thing to say about the double wishbone suspension is that it is costly. This suspension system is a lot more complex than the MacPherson suspension, which means it costs the manufacturers more money to create it. There are so many components and parts of the double wishbone suspension system.

How many links are there in the double wishbone suspension system?

* The 5-Link Double Wishbone Suspension Layout As shown below, the 3-link and 4-link layouts allow for movement in two or more directions.

What is a double wishbone suspension system?

Fig.1: Double wishbone Suspension system It is popular as front suspension mostly used in rear wheel drive vehicles. Design of the geometry of double wishbone suspension system along with design of spring plays a very important role in maintaining the stability of the vehicle.

How to choose a wishbone?

A single wishbone or A arm can be also used in various cases. Initially material of the wishbone is selected considering strength and cost. To determine various design parameters such as length of wishbones, tie rod length, coil length, suspension geometry is drawn.

How to design a suspension system?

To determine various design parameters such as length of wishbones, tie rod length, coil length, suspension geometry is drawn. The designed A arms are then modelled using CATIA software and then analysis is done using ANSYS or CATIA. The next step of designing is to decide various dimensions of the components of the system.

What is the functional objective of a suspension system?

Pursuing B.E. in Mechanical Engineering JSPMs Rajarshi Shahu College of Engineering Abstract The functional objective of the suspension system is to provide relative motion between the sprung and the unsprung mass. This is achieved by a spring to absorb the shocks and some kinematic linkages holding them together with particular degrees of freedom.
