COUPLING DEVICE BETWEEN LEFT AND RIGHT WHEELS OF VEHICLE

摘要

A coupling device between left and right wheels of a vehicle includes a differential gear, a driving source, a first power transmission system and a pair of second and third power transmission systems. The differential gear has a first rotational element and second and third rotational elements, one of which rotates forward, the other of which rotates in reverse. The driving source is coupled to the first rotational element. The first transmission system couples the second rotational element to the left or right wheel. The-second and third power transmission systems couple the third rotational element to the other wheel. The gear ratio of the third power transmission system differs from the gear ratios of the first and second power transmission systems which are equal to each other.
