Abstract:
A hybrid electric drive train for a motor vehicle comprises an engine with a drive shaft, an electric motor operable of motoring and generating, a differential transmission, and a multi-stage transmission with two input shafts and at least one output shaft. The differential transmission includes a planetary gear set, a clutch and a brake. The planetary gearset has a first element connected to the motor and the second input shaft of the transmission, a second element connected to the engine shaft, and a third element connected to the first input shaft of the transmission. The clutch is located between any two elements of the planetary gear set, and the brake is connected to the engine shaft. The transmission has a plurality of gearsets, and the driving gears of odd-numbered gearsets are mounted on the first input shaft while the driving gears of even-numbered gearsets are mounted on the second input shaft. The engine shaft can achieve every gear ratio of the gearsets. In addition, the engine shaft can also achieve a plurality of derivative speed ratios.

Claim (Index 1):
A hybrid electric drive train of a motor vehicle comprising:\n a heat engine with a drive shaft; an electric motor with a rotor operable of motoring and generating; a planetary gear set having at least a first element, a second element and a third element, wherein said first element is connected to said motor rotor, and said second element is connected to said engine shaft; a clutch being installed between any two of the three elements of said planetary gear set; a brake being connected to said second element of said planetary gear set; a multi-stage transmission with a first input shaft, a second input shaft and at least one output shaft, wherein said first input shaft is connected to said third element of said planetary gear set, and said second input shaft is connected to said first element of said planetary gear set; said multi-stage transmission having a plurality of gearsets, including at least one reverse gearset, wherein the driving gears of the odd-numbered gearsets are mounted on said first input shaft, the driving gears of the even-numbered gearsets are mounted on said second input shaft, and the driven gears of all said gearsets are mounted on said output shaft; wherein while said clutch is engaged, if one of said gearsets is selected, said engine shaft has the gear ratio of the selected gearset, and said engine shaft can achieve every gear ratio of said gearsets if each of said gearsets is selected in turn; wherein while said clutch is disengaged, said engine shaft achieves a derivative speed ratio if one odd-numbered gearset and one even-numbered gearset are selected at the same time, and since a plurality of different combinations of one odd-numbered gearset and one even-numbered gearset can be selected in turn, said engine shaft can achieve a plurality of derivative speed ratios.
