Axle Drive

Axle Drive

 

a mechanism used in motor vehicles to transfer and increase the torque from a drive shaft to a vehicle’s powered wheels and, consequently, to increase its tractive force.

An axle drive transmits the rotation of a drive shaft through an angle of 90° to semiaxles. Most axle drives employ single or double gears and pinions. In a single gear and pinion unit the rotation is transferred from a small bevel gear to a large one. In addition to the bevel gear and pinion, whose axles are mutually linked, some passenger vehicles and a number of trucks employ a hypoid gear. In a double gear and pinion unit the rotation is transmitted through two pairs of pinions: the rotation of a small bevel pinion is transmitted through a large bevel gear and on from a small cylindrical gear to a large cylindrical gear. A double gear and pinion unit may be used to obtain a high gear ratio from a comparatively small axle drive since two pairs of gears are meshed. Some trucks have more complex axle drive featuring two gear ratios and a mechanism for shifting between them.

When coasting or at low load, it's front axle drive.
To support the trend, Bosch is readying several new products, including an integrated electric axle drive, 48-volt battery technology, brushless electric motor actuator and a thermal management system.
Going further, replacing traditional axle drive systems with wheel hub motors brings efficiency to the independent control of the wheel torque with fast and accurate actuation [1].
This is helpful if one wheel is in the air, since full axle drive torque is sent to the wheel that has grip.
