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.

Abstract: In a suspension for a steerable wheel of a vehicle with a semi-virtual steering axis, a wheel support is connected to vehicle structure by an upper arm and two lower rods, one supporting lateral loads, whereas the other supporting longitudinal loads and being located forwardly relative to the rod supporting lateral loads. In a non-steered wheel condition, an articulated joint connecting the lower rod supporting the longitudinal loads is located more outwardly. The arrangement is such that during steering with a wheel being on an outer side of the curve, an intersection point of projections on a horizontal plane of the lower rods is displaced more inwardly. In a steered wheel condition, with said wheel being on an inner side of the curve, projections on the horizontal plane of said lower rods meet at a point displaced longitudinally forwardly relative to the intersection point in the non-steered wheel condition.

Abstract: A motor-vehicle wheel suspension includes a lower oscillating arm, a damper unit, an upper oscillating rod and a vertical articulated rod. The suspension includes a toe control oscillating rod having an inner end pivotally connected to a supporting structure and an outer end pivotally connected to a wheel support. An articulation of the outer end of the toe control rod to the wheel support and the upper end of the vertical rod includes an articulation axle connected to the vertical rod. An eccentric cylindrical member is rotatably mounted on the articulation axle within a cylindrical cavity in the support and has an axis eccentric relative to the articulation axle. The articulation axle is connected to an adjustment ring, whose rotation determines a variation in the position of the wheel support and a resulting variation of the wheel toe angle.
