Claim Text:
1. A multiple planetary gear set with a limited slip transmission system comprises: a first planet carrier; a second planet carrier; a propelling input; a first output; a steering input; a second output; a first planetary gear assembly; a second planetary gear assembly; a central gear; the first planet carrier and the second planet carrier each comprises a carrier plate; the first planetary gear assembly and second planetary gear assembly comprises a ring gear, a sun gear, and a plurality of planet gears; the sun gear, the ring gear, the central gear, and the carrier plate being concentrically mounted about a central rotation axis; the propelling input being operatively engaged with the central gear; the steering input being externally and operatively engaged with the ring gears of both the first planetary gear assembly and the second planetary gear assembly, in order to rotate the ring gear of the first planetary gear assembly and the ring gear of the second planetary gear assembly in opposite rotational directions, wherein the steering input is a bevel gear, wherein the ring gears of both the first planetary gear assembly and the second planetary gear assembly each comprises a set of external bevel gear teeth, wherein the bevel gear is perpendicularly engaged to the set of external bevel gear teeth for the first planetary gear assembly and to the set of external bevel gear teeth for the second planetary gear assembly; the central gear being positioned in between the first planetary gear assembly and the second planetary gear assembly; the first planet carrier being positioned adjacent to the first planetary gear assembly, opposite to the central gear; the second planet carrier being positioned adjacent to the second planetary gear assembly, opposite to the central gear; the first output being axially connected to the carrier plate of the first planet carrier; and the second output being axially connected to the carrier plate of the second planet carrier.
