1.0 Suspensions
- A suspension is a system that relies on all the components working in harmony to perform their given function.
- When one part gets worn, the rate of stress transfer to other parts accelerates, so early detection of any wear will prevent major repairs and provide long-term savings for the truck owner.
Suspensions are designed to:
- Carry the load
- Provide stability against side sway
- Transfer driving and braking forces between frame and axles
- Resist drive and brake torque wind-up
- Produce suitable riding and cushioning properties
- Maintain axle alignment parallel to each other and perpendicular to the frame
- Provide minimum changes in drive axle pinion angles and slip joint movement
- Minimize load transfer between axles on tandems
- Provide sufficient vertical movement on tandems to maintain traction
Components Making Up the Suspension System Include:
- Leaf springs
- Air springs
- Torque Rods
- Bushings
- Spring pins / Shackle kits
- U-bolts
- Shocks
