Title:
MOTOR DRIVE FORCE TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/096308
Kind Code:
A1
Abstract:
[Problem] To provide a motor drive force transmission device capable of inhibiting and continuously using the excessive heat of an electric motor generated from continuously operating same over a long period of time. [Solution] A motor drive force transmission device (1) is provided with: a deceleration transmission mechanism (2) for transmitting the motor drive force to a rear differential (107); a first electric motor (3) coupled to the rear differential (107) via the deceleration transmission mechanism (2) and for generating a first motor drive force (a); a second electric motor (4) connected to the first electric motor (3) and the deceleration transmission mechanism (2) and for generating a second motor drive force (b); and an ECU (5) for outputting a control signal for driving the first electric motor (3) and the second electric motor (4) when a torque equal to or greater than a predetermined torque is required as the drive torque for the rear differential (107), and a control signal for alternately driving the first electric motor (3) and the second electric motor (4) when a torque less than the predetermined torque is required as the drive torque.
