Transmission and drive device for an at least partially electrically driven vehicle

A transmission (2) for an at least partially electrically driven vehicle (1), comprising:

• a first electric machine (3a), a second electric machine (3b), and a third electric machine (3c), each of the first, second, and third electric machines (3a, 3b, 3c) being rotationally driveable in a first direction of rotation (R1) and in a second direction of rotation (R2);
• an output shaft (4) at least indirectly operatively connected to the first, second, and third electric machines (3a, 3b, 3c);
• a first freewheel clutch (5a) of the first electric machine (3a) that at least indirectly transmits a drive power of the first electric machine (3a) to the output shaft (4) with a first ratio when the first electric machine (3a) rotates in the first direction of rotation (R1);
• a first freewheel clutch (5a) of the third electric machine (3c) that at least indirectly transmits a drive power of the third electric machine (3c) to the output shaft (4) with the first ratio when the third electric machine (3c) rotates in the first direction of rotation (R1);
• a second freewheel clutch (5b) of the first electric machine (3a) that at least indirectly transmits the drive power of the first electric machine (3a) to the output shaft (4) with a second ratio when the first electric machine (3a) rotates in the second direction of rotation (R2);
• a second freewheel clutch (5b) of the third electric machine (3c) that at least indirectly transmits the drive power of the third electric machine (3c) to the output shaft (4) with the second ratio when the third electric machine (3c) rotates in the second direction of rotation (R2);
• and
• a first gear stage (17) arranged in power flow between the first freewheel clutch (5a) or the second freewheel clutch (5b) of each of the first and second electric machines (3a, 3b) and the output shaft (4) to drive the output shaft (4) in a third direction of rotation (R3).

An at least partially electrically driven vehicle (13), comprising:

• a wheel (12) having a wheel hub (11);
• and
• a wheel hub motor (2) integrated into the wheel hub (11), the wheel hub motor (2) comprising:
• a first electric machine (3a) and a second electric machine (3b), each of the first and second electric machines (3a, 3b) being rotationally driveable in a first direction of rotation (R1) and in a second direction of rotation (R2);
• an output shaft (4) at least indirectly operatively connected to the first electric machine (3a) and the second electric machine (3b);
• a first freewheel clutch (5a) that at least indirectly transmits a drive power of the first electric machine (3a) to the output shaft (4) with a first ratio when the first electric machine (3a) rotates in the first direction of rotation (R1);
• a second freewheel clutch (5b) that at least indirectly transmits the drive power of the first electric machine (3a) to the output shaft (4) with a second ratio when the first electric machine (3a) rotates in the second direction of rotation (R2);
• and
• at least one first gear stage (17) in power flow between the first freewheel clutch (5a) or the second freewheel clutch (5b) and the output shaft (4) to drive the output shaft (4) in a third direction of rotation (R3).
