Abstract
A drive device for motor vehicles including one or more electric motors, each of which is associated with at least one drive wheel rotatable on a steering knuckle and drives the wheel via a step-down gearbox. The gearbox is installed in the wheel hub of the respective drive wheel and a disconnect device for coupling and decoupling the respective electric motor from the respective gearbox is provided. The steering knuckle is formed as an axle tube in which a drive shaft is rotatably mounted, the drive shaft being able to be brought into a driving connection to the rotor of the electric motor at the inner end of the shaft and to the input of the gearbox at the outer end of the shaft when it is to perform driving.
Claims5
A drive device for motor vehicles comprising at least one driving electric motor coordinated with at least one drive wheel rotatable respectively on a steering knuckle and driving a at least one drive wheel through a reduction gearbox, whereby the reduction gearbox is mounted in a wheel hub of the drive wheel, and a disconnect device for coupling and decoupling the respective the at least one electric motor from the gearbox wherein the steering knuckle is designed as an axle tube in which driveshaft is rotatably arranged and can be brought to a driving connection at its inner end with a rotor of the at least one electric motor and at an outer end with an input of a reduction gear when a propulsion is to occur, and
- wherein the driveshaft can be displaced back and forth in its axial direction between:
- an engaged position, between electric motor and driveshaft, and between driveshaft and reduction gear so that a positive engagement force transmission is effected, establishing the driving connection, and
- a disengaged position, in which the driving connection is disconnected.
