Abstract
An electric motor is placed around the axle of a vehicle but includes a rotor that does not contact the axle. A drive element is fastened to the axle and extends radially from the axle. The drive element for driving the axle is coaxially fastened to the axle but located laterally with respect to the electric motor. The rotor includes a disk that directly engages elements in a peripheral region of a drive element disk, the engagement occurring at a point remote from the axis of the axle.
Claims7
A device for driving a vehicle mounted on at least one driving axle fitted with wheels, the device comprising:
- at least one electric motor having a stator and a rotor mounted so as to rotate with respect to the stator, the rotor placed around the axle but not in contact with the axle;
- a drive element fastened to the axle and extending radially from the axle;
- the drive element being a drive disk coaxially fastened to the axle and located laterally with respect to the electric motor, along the axial direction of the axle, the drive element driving the axle;
- the motor having at least one stator disk and at least one rotor disk, the rotor disk and stator disk having opposing faces;
- a plurality of electrical windings being fixed to the face of the stator disk;
- a plurality of windings or permanent magnets being fixed to the opposing face of the rotor disk;
- and
- the rotor disk fastened to means for directly engaging elements in a peripheral region of the drive disk, remote from an axis of the axle.
