What is the primary task of the gears located on the axle?

The primary task of the gears located on the axle is to facilitate vehicle turning. When a vehicle is in motion, especially while navigating turns, the gears on the axle play a crucial role in allowing the wheels to rotate at different speeds. This differential action is essential because the outside wheels have to cover a larger distance than the inside wheels during a turn. The axle's gears help manage this difference in speed, ensuring smoother handling and improving the vehicle's overall stability and control during cornering.

Understanding how the axle functions in terms of gear mechanics is essential for grasping basic automotive principles. For instance, if all wheels were forced to turn at the same speed during a turn, it would result in tire skidding or excessive wear, leading to an uncomfortable ride and possible loss of control. Thus, the design and function of gears on the axle are integral to effective vehicle maneuverability.
