Operation principle of the present invention is as follows, referring to Fig. 1;
Pure electric running function: when Vehicle Driving Cycle requires while not being very high in city operating mode or to dynamic property, now the first magneto 1 and engine 4 are not all worked, and drive separately Vehicle Driving Cycle by the second magneto 10 by every trade star toothed disc assembly 9. Combination by controlling second clutch 13 and brake 14 under this operating mode with separate, can make vehicle travel under two gears. While being specially one grade, brake 14 participation work are fixed on gear ring 15 on mission case, utilize input planet carrier 17 outputs of sun gear 12 to realize deceleration, power transmission line is that the power of the second magneto 10 is by the sun gear 12 coaxial with the second magneto output shaft 29 one, through planetary gear 16, power is delivered on planet carrier 17, again by further by final gear 7-1, power being delivered on differential assembly 7 with the constant mesh gear 8 of planet carrier 17 one, thereby drive vehicle to advance. This gear lower ring gear 15 is fixing, and sun gear 12 is inputted, planet carrier 17 is exported and is suitably equipped with the number of teeth and can realizes larger gearratio, slows down and increases the power requirement while turning round to meet starting and climbing. When second gear, brake 14 unclamps, and second clutch 13 is in conjunction with being integrated 17 armfuls of gear ring 15 and planet carriers, and now sun gear 12 is inputted, planet carrier 17 is output as direct high. Power transmission be by the second magneto 10 to sun gear 12, then through planetary gear 16 to planet carrier 17, and pass to differential assembly 7 by constant mesh gear 8 by final gear 7-1, then be delivered on wheel 27 through power transmission shaft 33 by differential assembly 7. Car-backing function is realized: in the time that vehicle needs reverse travel, the second magneto 10 reverses, and utilizes the power transmission line of a grade to realize reverse travel function.
Engine 4 drives separately Vehicle Driving Cycle: under this operating mode, the second magneto 10 is not worked, engine 4 is worked, first clutch 11 combinations, power engages with jackshaft the first gear 5 through input shaft gear 3, by final gear 7-1, power is delivered on differential assembly 7 through jackshaft the second gear 6 again, realizes and drive Vehicle Driving Cycle function. When under this operating mode, engine 4 starts, the effect with input shaft gear 3 by the-magneto output shaft gear 2 of the first magneto 1, power can be delivered on engine output shaft, engine 4 rotating speed fast lifting, in rotating speed economic zone, are realized to motor assist function. When engine 4 is operated in after economy best region, can be used for charging to battery higher than the engine output of vehicle actual demand.
Hybrid power drives and travels: in the time needing larger power in vehicle traveling process, the second magneto 10 and engine 4 participate in driving work simultaneously, when the second magneto 10 utilizes pure electricity to travel one grade or second gear power path, engine 4 utilize power transmission line while driving Vehicle Driving Cycle separately, and the two final gear 7-1 place in differential assembly 7 forms the common driving in power interflow Vehicle Driving Cycle.
Increase journey pattern: when this mode of operation occurs in battery supply feed, now the first magneto 1 uses as generator, first clutch 11 separates, engine 4 power drive the first magneto 1 to generate electricity through the-magneto output shaft gear 2 with input shaft gear 3, by electrical power storage in battery.
Braking energy feedback: the second magneto 10, in generator mode of operation output negative torque, generates electricity in the time that vehicle sliding maybe needs to brake, and realizes energy and reclaims.
