Drive unit
First Claim
1. A drive unit, comprising:
- a prime mover including a first motor having a first output shaft, and a second motor having a second output shaft;
a first driveshaft that transmits torque from the prime mover to one of first and second drive wheels; and
a second drive shaft that transmits torque from the prime mover to other of the first and second drive wheels,wherein the first drive shaft and the second drive shaft are allowed to be rotated by different torques,the drive unit comprising;
a first gear train including gears rotating around axes parallel to a rotational center axis of the first output shaft that is formed between the first output shaft and the first driveshaft;
a second gear train including gears rotating around axes parallel to a rotational center axis of the second output shaft that is formed between the second output shaft and the second driveshaft;
a first rotary member that is arranged in the first gear train,a second rotary member that is arranged in the second gear train; and
a restriction device that is interposed between the first rotary member and the second rotary member to restrict a differential rotation between the first drive wheel and the second drive wheel by changing a torque transmitted between the first rotary member and the second rotary member.

Abstract
A drive unit a drive unit which can prevent an occurrence of an unintentional relative rotation between the right and the left wheels is provided. The drive unit comprises: a first motor connected to the first driveshaft and a second motor connected to the second drive shaft; a first torque transmitting route between the first motor and the first drive shaft; a second torque transmitting route between the second motor and the second drive shaft; a first rotary member arranged in the first torque transmitting route; a second rotary member arranged in the second torque transmitting route; and a restriction device that restricts a differential rotation between the first rotary member and the second rotary member.
