In addition, in the time of the long-time idling of equipment such as vehicle launch electric air-conditioning or long-time electric-only modeTravel or long distance reversing, when clutch 2 combinations that are connected with engine 1, one/bis-gear synchronized35 and three/tetra-keep off synchronized 32 is in neutral gear position, and engine 1 power is by speed changer the first driving shaft30 are delivered to electric generator 9, then drive electric generator 9 to generate electricity, and then can effectively ensure at vapourWhen car idling, the equipment such as electric air-conditioning normally use, and realize length and travel and grow distance apart from electric-only modeAstern condition.
Known by technique scheme, when automobile is at a gear or two gears or three gears or any two gears of four gearsBetween while switching, before switching, make one-level synchronized 71 and 72 combinations of one-level driving gear, drive motors8 power is by the second driving shaft 70, one-level gear pair, the second driven shaft 60, the second main speed reducing gear pairBe delivered to differential mechanism 50 and export, now drive motors 8 power can compensate and exist in gear handoff procedurePower interruption and reduction gearshift pause and transition in rhythm or melody, effectively reduce control difficulty; In addition, the technical program is by twoOverlap gear independently and realize speed change and the change of engine 1 and drive motors 8 and turn round, by sharing main subtractingSpeed driven gear 51 is realized the power coupling of power engine 1 and drive motors 8, adopts this structure to establishMeter has reduced the maximum bearing torque of two cover gears and maximum speed, simultaneously by the electric generator arranging9 and the bi-motor electric power system that forms of drive motors 8, also overcome single motor in prior art and mixed movingThe problem that cannot generate electricity when power system cannot be grown apart from pure motor driving and idling; Effectively ensure automobileIn the time of idling, the normal use of the equipment such as electric air-conditioning, realized long travel apart from electric-only mode andLong apart from astern condition, and by the small power generation motor 9 adopting, can effectively reduce its structure chiVery little, reduce and manufacture difficulty and cost, be conducive to the propagation and employment in market.
Finally it should be noted that: above each embodiment is only in order to the technical solution of the utility model to be described, andNon-to its restriction; Although the utility model is had been described in detail with reference to aforementioned each embodiment abilityThe those of ordinary skill in territory is to be understood that: the technical scheme that it still can be recorded aforementioned each embodimentModify, or some or all of technical characterictic is wherein equal to replacement; And these amendments orPerson replaces, and does not make the essence of appropriate technical solution depart from the model of the each embodiment technical scheme of the utility modelEnclose.
