Description

A kind of hybrid electric drive system
Technical field
The invention belongs to technical field of hybrid power, relate to a kind of hybrid electric drive system.
Background technology
Because the fuel oil power vehicle is to the pollution of environment and to the consumption problem of the energy, electronlmobil and hybrid vehicle have become one of motor field current hot of research and development.
As the disclosed a kind of driving system of hybrid vehicle of Chinese patent, its publication number is CN101204920A, this system is included as driving engine and the motor that driving device provides power, be used to receive the electrical generator of engine power generating, and be connected electrically in power supply between electrical generator and the motor, wherein this system also comprises double-clutch, and this double-clutch is connected between driving engine and electrical generator and the driving device, is used for optionally giving electrical generator or driving device with the transmission of power of driving engine.In this case, though can realize the series-parallel connection drive pattern of vehicle simply, but still there are some problems, it mainly is the mode that its electric generator structure adopts front and back bearings, the structure of duplex bearing has caused electrical generator to increase because of the trouble point of bearing like this, thereby make total system be easy to, greatly reduce the stability and the high efficiency of this system works because of bearing fault causes failure problems.
Summary of the invention
The objective of the invention is to have the problems referred to above, proposed a kind ofly to reduce trouble point, make the stability of its drive system work and the hybrid electric drive system that work efficiency improves greatly because of bearing by changing electric generator structure at existing technology.
Purpose of the present invention can realize by following technical proposal: a kind of hybrid electric drive system, this system comprise electrical motor and with electric electromechanics bonded assembly storage battery, described hybrid electric drive system outputting power from the power take-off shaft of electrical motor, it is characterized in that: described hybrid electric drive system also comprises electrical generator and can drive the driving engine of generator for electricity generation, electrical generator is electrically connected with above-mentioned storage battery, and the rotor of described electrical generator directly is connected on the output shaft of driving engine.
When storage battery energy was sufficient, driving engine was not worked, and storage battery provides the energy to electrical motor, and electrical motor outputting power from the power take-off shaft drives automobile etc. and travels.When storage battery energy is not enough, start the engine, engine operation converts chemical powers such as gasoline to mechanical energy and exports to electrical generator from the output shaft of driving engine, and drive generator for electricity generation, and then charge a battery, thus the work of battery traction electrical motor.
Electrical generator in this hybrid electric drive system adopts the structure of the electrical generator front and back bearings of the output shaft that directly is connected in driving engine by its rotor before having replaced, eliminated the problem that native system causes this system normally not move because of its bearing et out of order of electrical generator, realize its no bearing arrangement, promptly reduced the trouble point of native system, ensured the stability and the high efficiency of native system work because of bearing.
In above-mentioned a kind of hybrid electric drive system, the rotor of described electrical generator is to be connected on the output shaft of driving engine by the bolted ways of connecting.
Bolted can guarantee that the rotor of its electrical generator firmly is fixed on the output shaft of driving engine, guarantees the normal stable operation of this hybrid electric drive system.Simultaneously, also can adopt other modes to be connected.
In above-mentioned a kind of hybrid electric drive system, described electrical motor and electrical generator are the ISG motor, and structure is identical.
The motor of ISG motor for adopting the ISG technology to produce, electrical motor and electrical generator also can adopt the motor of other types, and its structure also can be different.
Compared with prior art, this hybrid electric drive system adopts the bolted ways of connecting that the rotor of electrical generator directly is fixed on the output shaft of driving engine, eliminated the problem that native system causes this system normally not move because of its bearing et out of order of electrical generator, realize its no bearing arrangement, significantly reduced the trouble point of native system because of bearing.Simultaneously, native system is simple in structure, and is easy to operate.

Fig. 1 is a structural representation of the present invention.
Among the figure, 1, electrical motor; 2, storage battery; 3, electrical generator; 4, rotor; 5, driving engine; 6, output shaft; 7, transmission gear; 8, retarder; 9, wheel.
The specific embodiment
Below be specific embodiments of the invention and in conjunction with the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiment.
As shown in Figure 1, this hybrid electric drive system comprises electrical motor 1, storage battery 2, electrical generator 3 and driving engine 5, electrical motor 1 all is connected with storage battery 2 with electrical generator 3, the rotor 4 of electrical generator 3 directly is connected on the output shaft 6 of driving engine 5, driving engine 5 can rotate by the rotor 4 that its output shaft drives electrical generator 3 and then electrical generator 3 generatings be charged to storage battery 2, this hybrid electric drive system outputting power from the power take-off shaft of electrical motor 1.
In the course of the work, when storage battery 2 energy were sufficient, driving engine 5 was not worked, and storage battery 2 provides the energy to electrical motor 1, electrical motor 1 outputting power from the power take-off shaft drives and electrical motor 1 power take-off shaft bonded assembly transmission gear 7 and retarder 8 work, and then drives wheel 9 and rotate.When storage battery 2 energy shortages, start the engine 5, driving engine 5 work convert chemical powers such as gasoline to mechanical energy and export to electrical generator 3 from the output shaft 6 of driving engine 5, drive electrical generator 3 generatings, and then accumulators 2 chargings, thereby storage battery 2 driving motors 1 work.
Electrical generator 3 in the present embodiment adopts the structure of electrical generator 3 front and back bearings of the output shaft 6 that directly is connected in driving engine 5 by its rotor before having replaced, eliminate native system because of the problem that electrical generator 3 its bearing et out of orders cause this system normally not move, realized its no bearing arrangement.Safety, stability and the high efficiency of this system works have been improved greatly.
Specific embodiment described herein only is that spirit of the present invention is made casehistory.The technical personnel of the technical field of the invention can be made various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
