Construction Of Automobile Half Shafts

The primary function of a half shaft is to transmit power between the differential and the drive wheels. Traditionally, half shafts were mostly solid, but with technological advancements, hollow shafts are now widely used in passenger cars to better control rotational imbalances. This type of half shaft has a universal joint at both its inner and outer ends, which connects to the reducer gears and the inner rings of the wheel hub bearings via splines on the universal joints, ensuring smooth and efficient power transmission to the drive wheels.
