This document discusses the purpose and operating principles of a conventional differential. It describes how a conventional differential divides engine torque between the drive axles to allow them to rotate at different speeds, such as when turning. It explains that differential pinions connect the drive ring gear and side gears to allow the wheels to rotate at different speeds. The document also briefly mentions no-spin differentials, which use clutches between the drive axles to improve traction when one wheel tends to slip.
