Abstract:
1. A power transfer apparatus for a vehicle including a rotational power supply, the apparatus comprising: a variable speed transmission adapted to convert the rotational power supply into a first power supply and a second power supply; a rotational outside gear coupled to the first power supply and adapted to rotate around a first axis, the rotational outside gear including: a rotational support body coupled to the second power supply and adapted to rotate around the first axis, the rotational support body including at least one body mounting location distal from the first axis, at least one differential gear rotationally mounted at the at least one body mounting location, the differential gear including a differential face coupled to the inside face, wherein rotation of the differential gear at the at least one body mounting location is proportional to a speed difference between the rotational outside gear and the rotational support body; an output shaft adapted to rotate around the first axis, the output shaft including a shaft face coupled to the differential face of the differential gear; wherein the power transfer apparatus includes only mechanical gearing positioned on parallel shafts; wherein the support body includes a main support body and a supplemental support body, the supplemental support body defining a first side and a second side; and wherein the differential gear comprises: a gear axle mounted to the main support body; a gear shaft rotatably mounted on the gear axle and passing through the supplemental support body; a first end gear attached to the gear shaft on the first side of the supplemental support body; and a second end gear attached to the gear shaft on the second side of the support body.
