Abstract:
A coupling device between left and right wheels of a vehicle, said coupling device being provided between the left and right wheels of the vehicle, comprising:a pair of first and second differential gears each having a first rotational element, and second and third rotational elements one of which rotates in normal direction while the other thereof rotates in reverse direction, respectively, relative to said first rotational element;a driving source which is selectively coupled via switching means to said first rotational element of said first differential gear and to said first rotational element of said second differential gear;wherein said second rotational element and said third rotational element of said first differential gear are coupled at a first gear ratio to one and the other, respectively, of the left and right wheels;wherein said second rotational element of said second differential gear is coupled to one of the left and right wheels at a second gear ratio; andwherein said third rotational element of said second differential gear is coupled to said the other of the left, and right wheels at a third gear ratio which is different from said second gear ratio.
