Suspension components Springs

The three purposes of any suspension system are?

• Convert potential energy into kinetic energy

• Maintain correct wheel alignment under all driving conditions

• Minimise shock forces transferred from the road wheels

• Convert kinetic energy into heat energy

• Support the vehicles weight

Spring rates may be ?

• coiled or leaved

• push or pull

• constant or variable

• tensile or compressive

Shock absorbers are designed to control?

• Suspension spring oscillations

• Passenger comfort only

• Bump but not bounce

• the body height

Variable rate springs are identified by

• their colour

• their uneven coil spacing

• their use of a separate plate

• the location of the lower spring mount

A coil spring will experience compressive force when a load is applied

• True

• False

Unsprung mass refers to any mass that is?

• towed by the parent vehicle

• supported by the spring

• all braking components

• not support by the spring

It is the suspension systems job to ensure the vehicle wheels remain in contact with the road surface in all driving conditions

• True

• False

An applied force is a ___________ or _____________ force acting on an object.

• Push or Pull

• Stop or Go

• Up or Down

• Lift or Lower

Torsion force can be described as a _________ motion

• Bending

• Compressive

• Sheering

• Twisting
