Abstract
The transmission has a power division transmission which is adapted to provide a variable speed division with a constant torque division. The power division transmission has three branches comprising a motor input shaft and two branched transmissions. Each branched transmission is associated with a separate output shaft. At least one further power division or differential transmission is associated with the branched transmissions and the input shaft and has a rotatable transmission part. This latter part is connected to a speed control means such that the degree of slip between the branched transmission output shafts can be varied and/or controlled.
