Document Type and Number:
Japanese Patent JP6852614
Kind Code:
B2
Abstract:
To provide a drive force distribution device of a vehicle which can control drive forces of left and right wheels without arranging a clutch between an electric motor and left and right axles.SOLUTION: A drive force distribution device 80 of a vehicle 100 comprises: an electric motor 8 which has a stator 4 rotatably supported to a vehicle body, and a rotor 6 relatively rotatable with respect to the stator 4, and in which the stator 4 is connected to a right wheel 60, and the rotor 6 is connected to a left wheel 62; a reverse rotation mechanism 30 which is arranged between the stator 6 and the right wheel 60, and outputs the rotation of the stator 6 to the right wheel 60 by reversely rotating the stator; wheel brakes 46, 48 which can independently add brake forces to the right wheel 60 and the left wheel 62; and a distribution control device 56 for controlling the brake forces of the wheel brakes 46, 48. By this constitution, even if a clutch is not arranged, the brake forces of a pair of the wheel brakes 46, 48 are controlled by the distribution control device 56, and thus, a distribution of the drive forces to the left and right wheels 60, 62 is controlled.SELECTED DRAWING: Figure 1
