Title:
ELECTRIC DRIVE DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2013/069135
Kind Code:
A1
Abstract:
Provided is an electric drive device for a vehicle with increased design freedom. Brakes (Ba, Bb) are provided as engaging devices respectively between the output shaft (26) of a motor (MG) and left and right drive wheels (16a, 16b). By changing the slip ratio of the brakes (Ba, Bb), rotational speed difference can be applied to the left and right drive wheels (16a, 16b) in the same manner as a differential gear without providing a differential gear. Thus a differential gear can be removed, thereby increasing design freedom and facilitating the design of the center of gravity of the motor (MG).
