Embodiment Construction

[0014] The associated motor vehicle is not shown, which is expediently equipped with a generator driven by an internal combustion engine, but can also be equipped only with dry cells or accumulators or a connection to a stationary grid for feeding the electric motor. As an exemplary embodiment for the invention, an oscillating drive shaft 1 is shown, which has two driven double wheels 2 and 3, in Figures 2 to 4 The two wheels 3 on the right side are shown respectively in section in order to show the internal structure.

[0015] The twin wheels 3 are rotatable on a steering knuckle S and are driven by an electric motor E via a reduction gear, here a double-stage planetary transmission G. The planetary gear transmission G and the brake B are installed in the hub of the drive wheel 3 . In addition, a separating device is provided, which will be described below.

[0016] The steering knuckle S is designed as an axle tube in which the drive shaft W is rotatably mounted. When dr...

Abstract

The invention relates to a drive device for motor vehicles comprising one or more electric motors E, each of which is associated with at least one drive wheel (2; 3) rotatable on a steering knuckle and drives said wheel via a step-down gearbox G, wherein the step-down gearbox G is installed in the wheel hub of the respective drive wheel and wherein a disconnect device for coupling and decoupling the respective electric motor E from the respective gearbox G is provided. The steering knuckle S is formed as an axle tube in which a drive shaft W is rotatably mounted, said drive shaft W being able to be brought into a driving connection to the rotor R of the electric motor E at the inner end (4) of the shaft and to the input of the step-down gearbox G at the outer end 5 of the shaft when it is to perform driving. The drive shaft W can be shifted back and forth in the axial direction thereof between an engaged position, in which there is a positively engaged force transmission and thus the above-mentioned driving connection between the electric motor E and the drive shaft W on the one hand and the drive shaft W and the step-down gearbox G on the other hand, and a disengaged position in which the aforementioned positively engaged force transmissions, and thus the drive connection, is inoperative, the drive shaft W therefore forming the disconnect device.

Description

technical field [0001] The invention relates to a drive device for a motor vehicle comprising one or more electric motors respectively assigned to at least one drive wheel rotatable on a steering knuckle and driving said drive wheel via a reduction gear, The above-mentioned reducer is installed in the hub of the corresponding drive wheel, and the driving device is provided with a disconnecting device for coupling and disconnecting the corresponding electric motor with the corresponding reducer. Background technique [0002] Such a drive is known from DE 10121372 A1. The disconnecting device is an externally manually operable element located between the electric motor and the transmission, which should be able to disconnect the transmission in the event of a failure of the electric motor. Although it is mentioned that electrical or pneumatic separation should also be possible from the inside of the vehicle, no way of realizing such a separation device is given. [0003] Fur...
