Kind Code:
A1
Abstract:
Provided is a power transmission device capable of reducing a weight deviation and a drive torque deviation. A power transmission device (10) comprises: a differential device (13) that distributes a drive torque to a first output shaft (11) and a second output shaft (12); a first planetary gear device (20) and a second planetary gear device (30) each equipped with a first element, and a second element and a third element that rotate in conjunction with the first element; and a linking part (37) that links the third element of the first planetary gear device and the third element of the second planetary gear device. The first output shaft is coupled to the first element of the first planetary gear device, and the second output shaft is coupled to the first element of the second planetary gear device. The second element of the first planetary gear device has a control motor (28) attached thereto, thereby regulating the rotation of the second element of the second planetary gear device.
