Understanding Rack and Pinion Mechanisms
How Rack and Pinion Works
Rack and pinion systems consist of two main components: the rack, a linear gear, and the pinion, a circular gear. When the steering wheel is turned, the pinion rotates and engages the rack, translating the wheel’s motion into lateral movement. This system provides precise steering control, enhancing vehicle handling.
Components of a Rack and Pinion System
A typical rack and pinion assembly includes:
- Rack Gear: The straight gear that moves side to side.
- Pinion Gear: The round gear connected to the steering shaft.
- Tie Rods: Connect the rack to the steering arms at the wheels.
- Steering Shaft: Connects the steering wheel to the pinion.
Choosing the Right Rack and Pinion Parts
