Axle


Axle delivers torque to the wheels. Commonly referred to as a "CV Axle" or "Axle Shaft" or "Half Shaft" or "Drive Axle." A shaft around which a wheel revolves. It is considered "live" if it transmits power to the wheels. It is also called a "beam" or "dead" if it doesn't do anything other than support the wheels.

An axle is a shaft or a beam with a wheel at the end supporting a vehicle, on which one or more wheels turn. Axles that transmit power are called live axles. A live axle assembly contains two axle shafts that deliver power from the differential gears to the wheels. Its made up of special alloy steel, and these axle shafts have splines at their inner ends that fit into matching splines on the differential side gears. On the other hand, a dead axle or non-drive axle carries part of the weight but does not drive the wheels. A drive axle on which the wheels can pivot for steering is a steerable drive axle. It is commonlyly used on four-wheel-drive truaxle assembly contains two axle shafts that deliver power from the differential gears to the wheels.
