Title:
COAXIAL DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/023905
Kind Code:
A1
Abstract:
This coaxial drive device which drives a pair of axles rotatable about a first axis comprises: a motor that is coaxial with the first axis; a differential that is coaxial with the first axis, that is rotatable about the first axis, and that is provided with a differential gear set which differentially outputs a received torque to the pair of axles; an output shaft that penetrates through the motor, that is driven by the motor to rotate about the first axis, and that has a through hole sized to allow one of the pair of axles to reach the differential from the outside; a transmission shaft that is rotatable about a second axis parallel to the first axis and that meshes with both the output shaft and the differential to transmit the torque from the motor to the differential; a clutch that is disposed between the motor and the differential gear set and that restricts the differential of the differential gear set, or a clutch that is disposed above the transmission shaft and couples, in a decouplable manner, the output shaft and the differential with each other; and an actuator that is disposed above the first axis and that drives the clutch.
