Abstract
An independent suspension for vehicles, in particular for transporting people and/or materials, including a hub defining a rotation axis of the wheel of the vehicle, an electric motor, operatively connected to the hub and configured to rotate the hub and a support element operatively connected to the hub and developing, with a planar shape, along its own main development direction transverse to the rotation axis of the wheel. The support element is arranged below the hub and the electric motor. The electric motor develops within a containment volume defined at least partially by the support element.
Claims18
An independent suspension for a vehicle, comprising:
- a hub defining a rotation axis of a wheel of the vehicle;
- an electric motor, operatively connected to the hub and configured to rotate the hub;
- only a single support element operatively connected to the hub to support the hub, the support element having a frame side portion having a pivot axis upon which the support element pivots with respect to the frame and a hub side portion connected to the hub, thereby establishing a main development direction of the support element between the frame side portion and the hub side portion, the main development direction being transverse to the rotation axis of the wheel, the support element extending along the main development direction, wherein said pivot axis is positioned radially, with respect to the rotation axis of the wheel, beyond a radial extent of a tire mounted to the wheel and wherein the support element is substantially arranged at a lower vertical level than said rotation axis of the wheel and said electric motor and substantially forward of, or rearward of, the hub,
- wherein said hub side portion comprises only a single hinge point, aligned with the rotation axis of the wheel,
- wherein said electric motor extends within a containment volume defined at least partially by said support element, and
- wherein said support element comprises a spring or absorber and a damper developing vertically relative to said support element, said spring or absorber and/or said damper defining a height of said containment volume, wherein said support element also comprises a generally planar portion extending along the main development direction and configured to connect to the spring or absorber and the damper.
