Abstract:
1. A driving wheel structure for a motor vehicle employing an in-wheel motor arrangement, comprising: a first electric motor and a second electric motor that generate drive torques to rotate a wheel; a first support member that supports the first motor on a vehicle body; and a second support member that supports the second motor on the vehicle body, wherein the first support member is attached to the vehicle body such that, when the wheel is rotated in one direction by the first motor, a first reaction torque is induced about a momentary center of swing movement of the first support member by the drive torque of the first motor and the first reaction torque applies a downward bias force to the wheel, wherein the second support member is attached to the vehicle body such that, when the wheel is rotated in said one direction by the second motor, a second reaction torque is induced about a momentary center of swing movement of the second support member by the drive torque of the second motor and the second reaction torque applies an upward bias force to the wheel, and wherein the momentary centers of swing movement of the first and second support members are each offset from an axle shaft of the wheel in a longitudinal direction of the vehicle.
