Presentation Transcript

  1. Functions of a Steering System • Provide precise control of the wheel direction • Maintain correct steering effort • Transmit road feel to the driver’s hands • Absorb most of the road shock going to the steering wheel • Allow for suspension action

  2. Gear Mechanisms

  3. Steering Basic Linkage Steering (Worm Gear) Basic Rack-and-Pinion Steering

  4. Basic Steering Systems • Two basic kinds of steering systems are in use today: • linkage (worm gear) steering systems • rack-and-pinion steering systems • Each may be operated manually or with power assist

  5. Steering Gears Rack-and-Pinion Gear Worm Steering Gear

  6. Steering Gear Principles • Two basic types of gear mechanisms are found in steering gearboxes: • worm gears • rack-and-pinion gears

  7. Steering Column Components

  8. Steering Column Assembly • Consists of the steering wheel, steering shaft, column, ignition key mechanism, and a universal joint • Bolts to the underside of the dash • Sticks through the cowl and fastens to the steering gear
