Patent ID: 7156766

Claim:
A differential drive having an input element (E) and three output elements (A 1 , A 2 , A 3 ) which relative to one another comprise a differential effect and wherein there exists a fixed ratio between the input torque introduced via the input element (E) and each of the output torques directly transmittable to the output elements and wherein one of the output elements (A 3 ) can be connected via at least one coupling (K 1 , K 2 ) to each of the two other output elements (A 1 , A 2 ); and wherein by varying the individual coupling torques of the couplings (K 1 , K 2 ), it is possible to vary the input torque introduced via the input element (E) as well as the distribution of the input torque between the first one and the second one of the output elements (A 1 , A 2 ) and, wherein the input torque between the input element (E) and the first output element (A 1 ) is varied separately from the input torque between the input element (E) and the second output element (A 2 ).
