Further, on the basis of the foregoing description, also comprise a control system, described first motor 30, described second motor 40, the described first arrangement of clutch C1 and the described second arrangement of clutch C2 are electrically connected with described control system, promptly control the mode of operation of first motor 30 or second motor 40 easily by control system.
Hybrid electric drive system described in the present embodiment has following four kinds of mode of operation:
One, pure motorized motions pattern: driving engine 10 does not start, the first arrangement of clutch C1 is in disengaged condition, the second arrangement of clutch C2 is in engagement state, first motor 30 is made electrical motor and is used, to the power supply of first motor 30, the rotation that control system is controlled first motor, 30 rotors passes to the sun wheel 22 of sun and planet gear by rotor shaft by closed-center system, and the rotation of sun wheel 22 drives the rotation of pinion carrier 23, thereby drive the rotation of wheel drive shaft 50, and then drive wheels.Second motor, 40 idle running, not consumed energies.Can adjust the rotating speed and the torque of first motor 30 according to the operating mode needs.Because gear ring 21 is in engagement state with casing, gear ring 21 is fixing, and the rotating speed of first motor 30 is exported by sun and planet gear with certain gear ratio, by first motor, 30 independent drive vehicle '.In order to bring into play the advantage of native system to greatest extent, can the planetary size of appropriate design, make electrical motor with high raising speed specific output, do like this and help reducing motor volume, save interior space.
Two, combination drive pattern: driving engine 10 starts, the first arrangement of clutch C1 is in disengaged condition, the second arrangement of clutch C2 is in disengaged condition, driving engine 10 is by gear ring 21 outputting powers, power is passed to tween drive shaft 51 after pinion carrier 23 is transmitted, drive second motor 40 and wheel drive shaft 50 rotations, and then powered vehicle.First motor 30 that link to each other with sun wheel 22 this moment can be used as buncher, with the coupling of driving engine 10 rotating speeds, makes the operating range in the efficient district of engine fuel wideer; Second motor 40 that links to each other with tween drive shaft 51 can be looked operating mode and start, with the motor torque coupling, for drive system provides more powerful motivation.
Three, driving engine directly drives pattern: after driving engine 10 starts, the first arrangement of clutch C1 is in closure state, the second arrangement of clutch C2 is in disengaged condition, driving engine 10 is by gear ring 21 outputting powers, the structure because gear ring 21 and pinion carrier 23 are connected as a single entity, engine power is exported to wheel drive shaft with 1:1.This moment, sun wheel 22 was driven, can control first motor, the 30 rotors idle running that links to each other with sun wheel 22, promptly controlled described first motor, 30 stator no powers by control system; Can also control the coupling of first motor, 30 rotating speeds and driving engine 10 rotating speeds, make driving engine 10 be operated in efficient district better.
The working process of hybrid electric drive system described in the foregoing description is as follows:
At first, when vehicle start, low speed (less than first preset vehicle speed), first clutch C1 is in disengaged condition, second clutch C2 is in engagement state, start first motor 30, give first motor 30 power supplies by closed-center system, by first motor, 30 independent drive vehicle start and low speed drivings; Certainly, system also can be provided with and use second motor, 40 powered vehicle to start.Electric-only mode also is applicable to operating modes such as low speed driving under the bad situation of road conditions and climbing.
When the speed of a motor vehicle is higher than first preset vehicle speed, engage the first arrangement of clutch C1, open the second arrangement of clutch C2 simultaneously, driving driving engine 10 by second motor 40 starts, when driving engine 10 reaches certain rotating speed, in the time of can turning round by self oil circuit, open the first arrangement of clutch C1, and regulate the rotating speed of first motor 30, make the whole speed of a motor vehicle steady.Because the said process time is very short, in general 1 second, so car body can not felt strong vibrations, and the speed governing by first motor 30, can make the speed of a motor vehicle more steady.Driving engine 10 is by the output of sun and planet gear 20 reductions of speed, rotating speed according to regulating working conditions first motor 30, make the coupling of driving engine 10 and first motor, 30 rotating speeds, first motor 30 can also be done electrical generator where necessary and use, consumption of engine 10 excess energies make driving engine 20 be operated in fuel oil and efficiently distinguish.In case of necessity, second motor 40 starts, by first motor 30 or closed-center system power supply, with the motor torque coupling, for system increases torque.Drive system is operated in the combination drive pattern.
When the speed of a motor vehicle needs further to improve, when being higher than second preset vehicle speed, driving engine 10 can not satisfy the operating mode demand by the output of sun and planet gear 20 reductions of speed, continuing to use mixed mode to be about to make it to break away from fuel oil efficiently distinguishes, by making vehicle enter driving engine direct drive pattern: the closed first arrangement of clutch C1, and make the second arrangement of clutch C2 keep throwing off, driving engine 10 drives gear ring 21 and pinion carrier 23 synchronous rotating band motor-car wheel drive shafts 50, be that engine-drive is than being 1:1, the energy output of driving engine 10 all is used for drive wheels, at this moment, vehicle enters driving engine and directly drives pattern, is promptly advanced by driving engine 10 direct drive vehicles; Certainly, above-mentioned various mode of operations can be adjusted according to actual conditions in good time, also can use separately.Hybrid electric drive system described in the utility model utilizes the output of 20 pairs of driving engines 10 of sun and planet gear to carry out reduction of speed, make driving engine 10 enter the work of efficient district fast, when driving engine 10 is in the work of efficient district, driving engine 10 direct drive vehicles advance, do not need through sun and planet gear 20 speed changes, the noenergy transmission loss, thereby improved efficiency of engine, saved the energy greatly.
