Principles of suspension
|
Sprung mass refers to vehicle parts supported on the springs, such as the body, frame, and engine. Unsprung mass includes parts of the steering and suspension not supported by springs, such as wheels, tyres, brake assemblies.
|
Suspension force
|
Leaf springs absorb applied force by flattening out under load. Coil springs absorb force of impact by twisting. Torsion bars twist around their centre.
|
Unsprung weight
|
Parts of a vehicle not supported by the suspension system are known as unsprung weight.
|
Wheel unit location
|
Driving thrust, braking torque, and cornering force operate to displace wheel units. These forces must be transferred to the vehicle frame, but the wheel units must stay aligned with each other, and with the frame.
|
| Dampening |
Dampening prevents or reduces the bouncing effect of oscillation by absorbing the energy from the oscillation. |
