They mate the teeth on the axle shaft. The axle hub spins along with the wheels bolted to it and provide power to the wheels in order to rotate.

When the front hubs are locked, even if no power is sent to the front axle (by means of a transfer case ), the turning of the wheels will still spin the front ...
Concept (top view): In a vehicle, motors M1 through M4 drive respective wheels independently, possibly through respective gear arrangements. Individual-wheel drive (IWD) is an automobile design in which the vehicle has an all-wheel drive powertrain that consists of multiple independent traction motors each supplying torque to a single drive wheel.
