COAXIAL DRIVE UNIT

A coaxial drive unit is provided with a motor coaxial with a first axis. The drive unit has a differential that is coaxial with the first axis and includes a differential gear set for differential torque transmission to paired axles, an output shaft driven by the motor to rotate about the first axis and having a through-hole that allows one of the paired axles to reach the differential from an exterior. A transmission shaft is rotatable about a second axis parallel with the first axis and in mesh with both the output shaft and the differential to transmit the torque from the motor to the differential, a clutch is disposed between the motor and the differential gear set to limit a differential motion or disconnectably connect the output shaft with the differential, and an actuator is disposed above the first axis and configured to drive the clutch.
