  • Patent number: 9616922
    Abstract: Provided is a vehicle which, when a pair of left and right wheels are displaced with respect to the vehicle body due to the difference in drive force between the wheels, the two wheels are reliably displaced vertically in opposite directions such that neither wheel is disproportionately displaced and such that both wheels are steered during said displacement of both wheels vertically in opposite directions. An electric motor applies drive torque to the front wheels individually. A vehicle body frame supports the front wheel support member to allow rotation about a forwardly inclined steering axis (Lf). By allowing rotation of the front wheel support member about the steering axis (Lf), the front wheels are displaced relatively to one another vertically in opposite directions with respect to the vehicle body frame and the front wheels are steered.
