In sum, due to driving engine in the present embodiment 4, first motor 5 and the second motor 6 can separate work, that is: driving engine 4 can drive the intermediate gear 9 on tween drive shaft 3 to revolve round the sun around the axis of input shaft 1 by input shaft 1, first motor 5 drives the first gear 7 to rotate around input shaft 1 by the first speed reduction gearing 11, second motor 6 can drive the second gear 8 to rotate around the axis of output shaft 2, first gear 7, second gear 8 and intermediate gear 9 can carry out power coupling and dynamic branch according to the point of engagement place of respective rotating speed between gear, and the power after coupling is directly or indirectly delivered on drive axle by the second gear 8 and output shaft 2, and then drive vehicle to travel.
Because the speed of driving engine 4, first motor 5 and the second motor 6 can independently adjust, different rotational speed matches can obtain different mode of operations, described in specific as follows.
Three propulsion source output modes: driving engine 4, first motor 5 and the second motor 6 work simultaneously, as shown in Figure 4.Driving engine 4 drives tween drive shaft 3 to rotate around this input shaft 1 by input shaft 1, tween drive shaft 3 drives intermediate gear 9 to rotate around input shaft 1, intermediate gear 9 can drive the second gear 8 to rotate, that is: the power provided described in driving engine 4 will be delivered on tween drive shaft 3, intermediate gear 9 and the second gear 8 successively.First motor 4 drives the first gear 7 to rotate by the first speed reduction gearing 11, first gear 7 drives intermediate gear 9 to rotate, intermediate gear 9 drives the second gear 8 to rotate, that is: the power that the first motor 5 provides will be delivered to the first speed reduction gearing 11, first gear 7, intermediate gear 9 and the second gear 8 successively.Second motor 6 drives the second gear 8 to rotate around the axis of output shaft 2, that is: power is directly passed to the second gear 8 by the second motor 6.That is, the power that three propulsions source provide is coupled between the gear be meshed, power after final coupling will be delivered to output shaft 2 and the second speed reduction gearing 12 successively by the second gear 8, second speed reduction gearing 12 slows down after increasing turns round, finally power is delivered to drive axle, thus drive vehicle to travel, and realize stepless change.In addition, under this kind of mode of operation, only need carry out speed governing to the first motor 5, driving engine 4 just can be made to be in optimum Working all the time, thus improve the fuel economy of car load.
Dual power source output mode: simultaneously work for two motors as shown in Figure 5, is now electric-only mode.First motor 5 drives the first gear 7 to rotate by the first speed reduction gearing 11, first gear 7 drives intermediate gear 9 to rotate, intermediate gear 9 drives the second gear 8 to rotate, that is: the power that the first motor provides is delivered to the first speed reduction gearing 11, first gear 7, intermediate gear 9 and the second gear 8 successively.Meanwhile, the second motor 6 drives the second gear 8 to rotate around the axis of output shaft 2, that is: power is directly passed to the second gear 8 by the second motor 6.That is, the power provided described in two motors is coupled between the gear be meshed, power after final coupling will be delivered to output shaft 2 and the second speed reduction gearing 12 successively by the second gear 8, second speed reduction gearing 12 slows down after increasing turns round, finally power is delivered to drive axle, thus drives vehicle to travel.Under this kind of mode of operation, first motor 5 and the second motor 6 can carry out speed governing by control system, when the first motor 5 speed governing is to when can ensure that tween drive shaft 3 and housing 10 ensure motionless (that is: engine running), double-motor power can be realized export, and after being turned round by the second speed reduction gearing 12 reduction of speed increasing, power is delivered to drive axle, thus vehicle is driven to travel.In addition, under this kind of mode of operation, even if the variation range of the speed of a motor vehicle is comparatively large, due to two motors can speed governing to adapt to the change of the speed of a motor vehicle, under two motor moment can be made to be in efficient working speed state, thus avoid energy dissipation.It should be noted that it can also is that other two kinds of drive sources work simultaneously.
Brake energy recovery pattern: when car retardation or braking, driving engine 4 cuts out or is in idling mode, first motor 5 and the second motor 6 will be in power generation mode, as shown in Figure 6, the inertia torque of vehicle is delivered on the second speed reduction gearing 12 through drive wheel, second speed reduction gearing 12 passes to the second gear 8 again by output shaft 2, a part of torque is directly passed to the second motor 6 by the second gear 8, thus the second motor 6 is generated electricity, another part torque is passed to the first gear 7 by intermediate gear 9 by the second gear 8, then, this partial torque is passed to the first motor 5 by the first speed reduction gearing 11 by the first gear 7 again, thus the first motor 5 is generated electricity.It should be noted that in this mode, the first speed reduction gearing 11 and the second speed reduction gearing 12 role are accelerating function, to improve charging rate.
In addition, can also realize single power source output mode, such as, only have the second motor 6 to work, now the second motor 6 is rotated with output shaft 2 by the second gear 8, realizes its Power output.Certainly, driving engine 4 or the first motor 5 can also be made to work independently outputting power, travel to drive vehicle.
Certainly, this dynamic coupling device can also realize locating above-mentioned outside other mode of operations, such as, series connection increases journey pattern etc., does not repeat them here.
In sum, except dynamic coupling device described in the present embodiment advantage that structure is simple except having, manufacture craft requirement is low and cost is low, can also multiple-working mode be realized, make driving engine be in optimum Working all the time, fuel economy and car load traveling comfort and NVH performance can be improved.
