For above-mentioned first arrangement of clutch 61; Can on the extended surface of gear ring 31, the male splines structure be installed near pinion carrier 33 1 sides; The friction lining of first arrangement of clutch 61 (or antithesis sheet) has the female splines structure; Be installed in extended surface 310 1 sides with nested type, the antithesis sheet (or friction lining) of said pinion carrier 33 1 sides is installed on the pinion carrier 33 in the same way.A side is connected in automobile hydraulic system in pinion carrier 33 or the gear ring 31, promotes gear ring 31 or pinion carrier 33 through hydraulic efficiency pressure system, and the friction lining of first arrangement of clutch 61 and the joint of antithesis sheet are perhaps separated.
As an alternative embodiment of the invention, said second arrangement of clutch 62 also can be a clutch with multiple laminated disc, and said multi-disc liquid clutch comprises friction lining and antithesis sheet, and the two selectively is installed in respectively on the gear ring outside and the said housing.
As an alternative embodiment of the invention, said closed-center system can be an electrokinetic cell.
Further; On the basis of the foregoing description; Also comprise a control system, said electrical generator 10, said electrical motor 40, said first arrangement of clutch 61, said second arrangement of clutch 62 are electrically connected with said control system, promptly control the mode of operation of above-mentioned parts easily through 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 20 does not start; First arrangement of clutch 61 is in disengaged condition, and second arrangement of clutch 62 is in engagement state, is supplied power to electrical motor 40 by closed-center system; The rotation of control system control motor 40 rotors passes to the sun wheel 32 of sun and planet gear through tween drive shaft 50; The rotation of sun wheel 32 drives the rotation of pinion carrier 33, thereby passes through the rotation that transmission gear 51 drives wheel drive shafts 52, and then drive wheels.Can be according to the rotating speed and the torque of operating mode needs adjustment electrical motor 40.Because gear ring 31 is in engagement state with casing, gear ring 21 is fixing, and the rotating speed of electrical motor 40 is exported through sun and planet gear with certain gear ratio, by electrical motor 40 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 20 starts, and first arrangement of clutch 61 is in disengaged condition, and second arrangement of clutch 62 is in disengaged condition; Driving engine 20 is through gear ring 31 outputting powers; Power is passed to tween drive shaft 50 after pinion carrier 33 is transmitted, wheel drive shaft 50 rotations, and then powered vehicle.The electrical motor 40 that link to each other with sun wheel 32 this moment can be used as buncher, with the coupling of driving engine 20 rotating speeds, makes the operating range in the efficient district of engine fuel wideer.
Three, driving engine directly drives pattern: after driving engine 20 starts; First arrangement of clutch 61 is in closure state; Second arrangement of clutch 62 is in disengaged condition; Driving engine 20 passes through gear ring 31 outputting powers, the structure because gear ring 31 and pinion carrier 33 are connected as a single entity, and engine power is exported to wheel drive shaft with 1:1.This moment, the electrical motor 40 that links to each other with sun wheel 32 can also be as buncher, or consumption of engine 20 superfluous power are used for generating electricity.
The working process of hybrid electric drive system described in the foregoing description is following:
At first, when vehicle start, low speed (less than first preset vehicle speed), first clutch 61 is in disengaged condition; Second clutch 62 is in engagement state; Give electrical motor 40 power supplies by closed-center system, by electrical motor 40 independent drive vehicle start and low speed drivings, vehicle is in electric-only mode.Electric-only mode also is applicable to operating modes such as low speed driving and the climbing under the bad situation of road conditions.
When the speed of a motor vehicle was higher than first preset vehicle speed, starter-generator 10 was opened second arrangement of clutch 62; Driving driving engine 20 by electrical generator 10 starts; Regulate the rotating speed of electrical motor 40 simultaneously, electrical motor 40 and the driving engine 20 coupling rotating speeds and the speed of a motor vehicle are adapted, make speed of a motor vehicle smooth transition steady.Driving engine 20 is through the output of sun and planet gear 30 reductions of speed; According to the rotating speed of regulating working conditions electrical motor 40, make driving engine 20 and the coupling of electrical motor 40 rotating speeds, electrical motor 40 can also generate electricity where necessary; Consumption of engine 20 excess energies make driving engine 20 more time be operated in fuel oil and efficiently distinguish.Drive system is operated in the combination drive pattern.
When further raising of the speed of a motor vehicle, when being higher than second preset vehicle speed, driving engine 20 can not satisfy the operating mode demand through the output of sun and planet gear 30 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 get into 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 20 drives gear ring 31 and pinion carrier 33 synchronous rotating band motor-car wheel drive shafts 52; Be that engine-drive is than being 1:1; The energy output of driving engine 20 all is used for drive wheels, and electrical motor 40 was done buncher equally and used this moment, at this moment; Vehicle gets into driving engine and directly drives pattern, is promptly advanced by driving engine 10 direct drive vehicles.
