What type of gear case is found on some ATVs that allows the wheels to spin at different rates?

A differential gear case is specifically designed to allow the wheels on an ATV to rotate at different speeds when cornering or maneuvering. This is crucial because, during a turn, the outside wheels travel a greater distance than the inside wheels. If both wheels were forced to spin at the same rate, it could cause tire wear, reduced traction, and may destabilize the vehicle.

The differential gear case allows for this difference in rotation, enhancing handling, stability, and overall safety while driving. It is a fundamental component in vehicles that need to navigate turns efficiently, as it helps ensure that the ATV remains stable without unnecessary strain on the drivetrain.

Understanding this function is vital for ATV operation, as it relates directly to safe riding practices, particularly in off-road conditions where turns and uneven terrain are common.
