Graduating power is to output shaft 13.Because, in shift process, motor A1 passes sequentially through planet row deceleration device, input shaft A6, three gears
Driving gear 7 and 34 gear driven gear 11 continued deceleration increases square output, thus ensure that in shift process power all the time not in
Disconnected；
(4) two gear fall one gear
When two gear switching one gears, the conjunction gear on three gear driving gears 7 is departed from synchronous gear sleeve A8, is exported by motor A1
Kinetic current to output shaft 13 temporarily interrupts, now, controlled motor A1 rotating speed to adjust synchronous gear sleeve A8 rotating speed, when a gear actively
When gear 10 is identical with synchronous gear sleeve A8 rotating speed, the conjunction gear on a gear driving gear 10 is combined with synchronous gear sleeve A8, motor
A1 continues through planet row deceleration device, input shaft A6, a gear driving gear 10 and one or two gear driven gears 12 and transmits power to
Output shaft 13.Because, in shift process, motor B24 passes sequentially through planet row deceleration device, input shaft B19, two gear driving tooths
Wheel 15 and 1 gear driven gear 12 continued deceleration increases square output, therefore ensure that power does not interrupt all the time in shift process；
The present invention provides a kind of dual-motor variable speed case of power failure-free, and this change speed gear box is defeated as power using two motors
Enter, during gearshift, can guarantee that power does not interrupt, simultaneously by the rotational speed regulation function of effective Shifting and bi-motor it is ensured that
Motor be in all the time efficient operation interval it is adaptable to start and stop frequently urban traffic situation；Additionally, by between motor and reduction box
Increase planet row deceleration device, change speed gear box of the present invention can select the motor that rotating speed is bigger, volume is less in choice of electrical machine
Coupling change speed gear box, saves the overall space of change speed gear box and motor, improves the economy of change speed gear box.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
