Abstract

A double axle drive includes at least one driving motor arranged between two drive axles, wherein the axis of rotation thereof extends transversely, in particular perpendicularly to the drive axles, where a wheel set shaft is drivable via a drive shaft of the driving motor via each transmission, and where the entire double axel drive is arranged in a housing unit that includes two housing parts.

Claims (12)

1. A double axle drive, comprising:

a plurality of drive axles; and

a single drive motor having a stator laminated core arranged in a rotatably fixed manner within a single housing unit having two housing sections connected to one another at a flange surface in a region of the stator laminated core, said single drive motor being arranged between the plurality of drive axles, and an axis of rotation of said drive motor extending transversely to the plurality of drive axles;

wherein a wheel set shaft is drivable via a drive shaft of the single drive motor via each transmission; and

wherein an entirety of the double axle drive is arranged in the single housing unit having the two housing sections.

2. The double axle drive as claimed in claim 1 , wherein the transmission is an angular transmission or a hypoid transmission.

3. The double axle drive as claimed in claim 2 , wherein the two housing sections have flange surfaces facing one another, upon which the two housing sections are fixable; and wherein the flange surfaces extend perpendicularly or parallel to the drive shaft.

4. The double axle drive as claimed in claim 1 , wherein the two housing sections have flange surfaces facing one another, upon which the two housing sections are fixable; and wherein the flange surfaces extend perpendicularly or parallel to the drive shaft.

5. The double axle drive as claimed in claim 4 , wherein the flange surface are arranged axially externally to a stator laminated core of the drive motor.

6. The double axle drive as claimed in claim 1 , wherein the transverse direction is a direction perpendicular to the plurality of drive axles.

7. The double axle drive as claimed in claim 1 , wherein one housing section of two housing sections includes a coolant inlet and another housing section of the two housing sections includes a plurality of outlets.

8. The double axle drive as claimed in claim 7 , wherein the coolant inlet and the plurality of coolant outlets allow a coolant to flow across at least the stator laminated core.
