Abstract: An electric vehicle includes a frame module carrying an electric motor unit and a suspension including, for each wheel, upper and lower oscillating arms connected to a wheel support by swivel joints which define a steering axis of the wheel. The suspension includes two shock absorber devices arranged in horizontal positions and along directions transversal with respect to a vehicle longitudinal direction, which is carried by the frame module centrally on the vehicle. Each shock absorber cylinder is operatively connected to a respective oscillating arm by an oscillating linkage member. Brake discs are arranged at remote positions with respect to the wheels, on two output shafts at two opposite sides of the motor unit, which, in one example, includes two electric motors and two respective gear reducer units from which project the output shafts carrying the brake discs; the latter connected to wheel hubs by respective drive shafts.

Abstract: An electric vehicle includes a suspension and powertrain unit having a vehicle frame module, an electric motor unit carried by the frame module centrally between two wheels and a suspension including, for each wheel, an upper oscillating arm and a lower oscillating arm carrying a respective wheel support. Each wheel support rotatably supports a respective wheel hub connected to the electric motor unit by a respective drive shaft. Brake discs are mounted on two output shafts of the electric motor unit, at a distance from the respective wheels, and are connected by drive shafts to the hubs of the two wheels. Thanks to the absence of brake discs adjacent to the wheel hubs, swivel joints connecting each wheel support to the respective upper and lower arms can be arranged so as to define a steering axis passing through a respective wheel center and thereby having a substantially zero kingpin offset.
