Gear mechanism is very vital part of the automotive systems. There are two types of steering gear mechanisms. They are as follows,

1. Davis steering gear.

2. Ackermann steering gear.

Difference between the above two mechanisms are as follows,

The sliding pair has more friction than the turning pair, therefore the Davis steering gear will wear out earlier and become inaccurate after
