What is wishbone type suspension?

The wishbone type is the most popular independent suspension system. It consists of two (occasionally parallel) wishbone-shaped arms to locate the wheel. The wishbones not only position the wheels and transmit the vehicle load but also rest acceleration, braking and cornering forces.

What is the advantage of an independent double wishbone rear suspension low profile design over solid axle rear suspension?

Uneven Surfaces. The greatest advantage of the independent rear suspension is its performance on uneven surfaces. The movement of each rear wheel is not affected by the other so the vehicle is able to maintain traction where a solid-axle vehicle might lose contact with the driving surface.

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.

What is the difference between unequal and non-parallel wishbones?

Unequal simply means unequal length, the upper is usually shorter than the lower (hence the shape of the front of the locost chassis). Non-parallel means just that, the upper and lower arms in most roadgoing double wishbone designs are not parallel, typically they will be converging towards the chassis.

Is there such a thing as a non-parallel suspension?

There is nothing like non parallel or unequal double wishbone suspension. Both forks are designed & mounted to frames/Chassis as per the packaging of vehicle, Clearance envelope, Suspension parameters etc. Thus there may be some angle and size are often different.

What is the purpose of the unequal and non parallel link system?

This system allows the user to select and optimize their own geometry (camber, caster, scrub radius, roll center etc.) The unequal and non parallel link set up reduces the positive camber of the laden wheel in roll. You can set the roll centre wherever you want at least in static condition.
