Wheels

Front axle

Steering system

Seats

absorb vibration and impact forces from the road surface

ensure that the steering wheel can deliver a suitable amount of steering force

ensure that wheel alignment is not disturbed during driving

automatically correct the effects of over steering

it is desired to reduce the unsprung mass

it is desired to have more flexibility in design

it is desired to improve type to ground contact characteristics

large changes in load make it necessary to have a large suspension stroke

The vertical size of the suspension can be made more compact

non vertical external forces are supported by the suspension arms

the unsprung mass in lighter

the assembly is slightly more complicated in design

absorb the energy

dissipate the energy

release the energy

increase the energy
