Abstract
A torque distributing differential for distributing torque from an input element to two output elements and including a first planetary carrier connected to one of the two output elements of the differential and a sun gear coupled to the other of the two output elements. A second planetary carrier of a planetary gear type torque distributing mechanism coupled to the other of the two output elements. An external tooth gear of a ring gear of the torque distributing mechanism and an external tooth gear of the first planetary carrier being operatively connected to each other with a predetermined reduction ration through a pair of spur gears, so that the sun gear is rotatably driven by a motor.
Claims16
A torque distributing mechanism in a differential, said differential including a single input element and two output elements for distributing torque applied to said input element of said differential to said two output elements at a predetermined proportion, said torque distributing mechanism comprising:
- a drive source;
- and
- a planetary gear mechanism, including
- (a) a ring gear,
- (b) a sun gear, and
- (c) a planetary carrier carrying a planetary gear meshed with said ring gear and said sun gear, a first one of three elements including said ring gear, said sun gear and said planetary carrier being coupled to one of said two output elements of said differential through a spur gear, a second one of the three elements including said ring gear, said sun gear and said planetary carrier being connected to the other of said two output elements of said differential, and a third one of the three elements including said ring gear, said sun gear and said planetary carrier being connected to said drive source.
