Five gear situations are described below: when automatic transmission is in five gears, first clutch 111 and second clutch 112 are in jointing state, 3rd clutch 113 is in off state, and the power that motor 201 exports exports the second single-row single-stage planetary gear train to after the first single-row single-stage planetary gear train coupling.Particularly, the power that motor 201 exports is passed to the first sun gear 134 by the first axle 101, first clutch 111, second axle 102 on the one hand, on the other hand, the power that motor 201 exports is passed to the first ring gear 131 by the first axle 101, second clutch 112, thus, the second ring gear 141 is passed to from the first row carrier 133 after the power coupling that the first ring gear 131 and the transmission of the first sun gear 134 come, now motor braking second sun gear 144, therefore power finally passes out from the second planet carrier 143.In the process, the first control unit 121 is not braked the first ring gear 131, second control unit 122 and is not braked the second ring gear the 141, three control unit 123 and do not brake the second axle 102.Automatic transmission is in speed ratio i5=(1+ the α 2)/α 2 during five gears.
Six gear situations are described below: when automatic transmission is in six gears, second clutch 112 and the 3rd clutch 113 are in jointing state, and first clutch 111 is in off state.The power that motor 201 exports exports after the coupling of the second single-row single-stage planetary gear train place.Particularly, the power that motor 201 exports is on the one hand through the first axle 101, the second sun gear 144 is passed to below after 3rd clutch 113 and the first gear pair will mentioned and the second gear pair, on the other hand, the power that motor 201 exports is through the first axle 101, the first ring gear 131 is passed to after second clutch 112, now the 3rd control unit 123 brakes the second axle 102, thus the first sun gear 134 does not rotate, therefore power is passed to the second ring gear 141 from the first row carrier 133, finally pass out from the second planet carrier 143 after this part power and the power coupling transmitted from the second sun gear 144.Automatic transmission is in speed ratio i6=(1+ α 2)/[1+ (1+ the α 1)/α 1] during six gears.
Seven gear situations are described below: when speed changer is in seven gears, first clutch 111, second clutch 112 and the 3rd clutch 113 are all in jointing state.The power that motor 201 exports exports respectively through after the first single-row single-stage planetary gear train and twice coupling of the second single-row single-stage planetary gear train.Particularly, the power that motor 201 exports is passed to the first sun gear 134 by the first axle 101, first clutch 111 on the one hand, on the other hand, a part of power that motor 201 exports is passed to the first ring gear 131 by the first axle 101, second clutch 112, exports the second ring gear 141 to after this part power and the power coupling being passed to the first sun gear 134 from the first row carrier 133.Again on the one hand, another part power that motor 201 exports, by being passed to second sun gear 144 after the first axle 101, the 3rd clutch 113 and the first gear pair will mentioned and the second gear pair below, finally passes out from the second planet carrier 143 after this part power and the power coupling being passed to the second ring gear 141.In the process, the first control unit 121 is not braked the first ring gear 131, second control unit 122 and is not braked the second ring gear the 141, three control unit 123 and do not brake the second axle 102.Automatic transmission is in speed ratio i7=1*1 during seven gears.
To sum up, the minimum speed ratio of automatic transmission is 1, certainly, is understandable that, for the ordinary skill in the art, can change base ratio to adjust the speed ratio of whole system.
Be understandable that, motor 201 also can not outputting power, and only by motor as power source, then now first clutch 111, second clutch 112 and the 3rd clutch 113 are all in off state, second control unit 122 brakes the second ring gear 141 simultaneously, after transmission of power to the second sun gear 144 that motor exports thus, due to the cause that the second ring gear 141 is braked, therefore power finally passes out from the second planet carrier 143, now automobile is in pure motorized motions pattern, speed ratio ie=(1+ α 2) when automobile is in pure motorized motions mode.
Wherein, be understandable that, just can realize pure electric drive automobile and move ahead by the rotating forward, the reversion that control motor and move backward, such as, can realize the pure motor driving mode of automobile when motor rotates forward, accordingly, when motor reversal, then automobile is in state of rolling backward, namely, when motor reversal and three clutches all disconnect, automatic transmission is in the state of reversing gear, and automatic transmission is in the speed ratio ir=(1+ α 2) when reversing gear state.
