Abstract
A gear box having a gear set therein for mounting to the outside of a housing of an axle assembly and connected to the input shaft of the differential of the axle assembly can allow high speed electric motor(s) to connect to the differential via the gear box for driving the axle assembly. The gear box can be mounted using existing bolt hole pattern on the axle assembly housing such as the input cover of the axle head assembly housing the differential. The gear set can be a planetary gear set where the rotor of the electric motor can be rotationally connected to the sun gear and the carrier gear can be connected to the input pinion shaft. In another embodiment an axle assembly having a differential can also have a gear box mounted to the outside of the axle housing and connected to the input pinion shaft to allow use of a high speed electric motor by providing an appropriate gear ratio conversion.
