RACK AND PINION EXAMINATION QUESTION |
|
V. Ryan © 2004 | |
1. The diagram
below shows a vehicle and its steering system. The most important part
of the mechanisms is missing. This allows the steering wheel to turn the
wheels left and right so that it can be steered. |
|
|
|
EXPLANATION: |
|
The rack and pinion gear system allows rotary motion of the steering wheel to be converted to linear motion. As the steering wheel is turned, the pinion gear also turns, driving the rack in the right or left direction, pointing the wheels in the desired direction. |
