Study Notes
Steering Fundamentals
- Steering systems precisely control wheel direction, maintaining correct steering, and transmitting road feel to the driver.
- Steering systems absorb road shock.
- Steering columns consist of steering wheel, shaft, column, ignition key mechanism, and sometimes a flexible coupling and universal joint.
Steering System Types: Rack and Pinion
- Most passenger vehicles use rack and pinion steering housed in one unit.
- Pinion gear meshes with a rack of gear teeth.
- The inside tire needs a sharper turn to follow a shorter radius.
Steering Angles
- The inside tire must make a sharper turn to follow a shorter radius.
Steering Linkage
- Primarily used on trucks, vans, and larger vehicles, but also on most passenger vehicles before 1980.
Ball Sockets
- Allow for motion in all directions between two connected parts.
- Some allow for lubrication with grease fittings and sealed units.
- Used in pitman arms, idler arms, and tie rods.
Power Steering
- Reduces driver steering effort.
- Many vehicles use hydraulic power steering, where an engine-driven pump uses fluid to assist the driver.
- More manufacturers are switching to electric power steering, using an electric motor to assist the driver.
Suspension Fundamentals
- Supports vehicle weight.
- Allows wheels to move up and down.
- Allows for rapid cornering without excessive body roll.
- Keeps tires in firm contact with the road.
- Prevents excessive body squat during acceleration or body dive during braking.
- Keeps wheels aligned for correct steering.
Shock Absorbers
- Convert kinetic energy into heat to dissipate.
- Reduce road shocks and vibrations, creating a smoother, more comfortable ride.
Steering Types
- Coil spring, leaf spring, torsion spring.
Spring Functions
- Support vehicle weight (sprung weight).
- Absorb road bumps.
Unsprung Weight
- Weight not supported by springs (tires, axles, wheel bearings).
Other Suspension Parts
- Control Arms: Connect steering knuckle to body, with bushings or ball joints.
- Steering Knuckle: Supports wheel bearings, connects to the steering system, enabling steering.
- Ball Joints: Allow for steering and suspension movements, lubricated with grease.
- Shock Absorbers: Limit spring movement for smoother ride; one end to frame/body, the other to axle or control arm.
Sway Bar/Stabilizer Bar
- Used to prevent excessive body lean during sharp turns.
- Made of spring steel, attached to lower control arms and frame.
- Twisting the bar counteracts body lean.
