Described herein are methods and systems of a rear axle of a commercial electric vehicle. In various embodiments, the rear axle includes a curved de Dion axle that includes stub axles, CV cups, each configured to receive a portion of a CV axle, and a central portion disposed downward and rearward of the stub axles. The rear axle includes a curved form factor to allow for a portion of an electric drive unit to be disposed in a manner where a hub centerline connecting the stub axles intersects the electric drive unit.

A method and apparatus for adapting a vehicle rear suspension wherein the apparatus comprises a substantially circular plate having first and second surfaces with a central bore therethrough and with closed and open notches extending into a circumferential edge thereof, a pair of outer mounting bores extending through the plate proximate to the circumferential edge with the closed notch therebetween and a plurality of first and second inner mounting bores distributed around the central bore. The method comprises removing a multi-link rear suspension assembly from the vehicle and removing left and right wheel assemblies from the multi-link rear suspension assembly mounting an adaptor plate to each of the left and right wheel assemblies on an inside surface thereof with a first set of fasteners, mounting an axle beam of a torsion bar rear suspension assembly to each of the adaptor plates with a second set of fasteners and securing the torsion bar rear suspension assembly to the vehicle.

A charger incorporated in a vehicle wheel supporting rolling bearing unit detects an output voltage of an electric generator and calculates a rotation speed of a hub. When a rotation speed of the hub is in a low speed state where a sensor and a wireless communication device are operated by electric power supplied 5 by a battery, a frequency of wireless communication performed between the wireless communication device and a calculator disposed on a vehicle body side is changed according to the rotation speed of the hub or a traveling speed of a vehicle.
