Description
Technical field
The invention belongs to electric vehicle engineering field, relate to a kind of auxiliary power unit for electric vehicle, be specifically related to a kind of auxiliary power unit for electric vehicle using torsional vibration damper.
Background technology
Along with orthodox car industrial expansion, oil resources are gradually deficient, air quality goes from bad to worse.Under these circumstances, the electronlmobil with obvious energy saving standard advantage becomes the focus that Ge great automobile vendor and scientific research institution competitively develop in recent years.Electronlmobil is considered to one of effective way solving energy shortage problem and problem of environmental pollution.
At present, the subject matter that faces of Development of Electric Vehicles: one is that continual mileage is short.On the one hand, due to the restriction of battery technology, the continual mileage of most of pure electric automobile only has 100 km; On the other hand, charging infrastructure construction is still far from perfect, and promoting the use of of pure electric automobile is very restricted.Two is that electronlmobil cost is high, and the topmost influence factor of cost is exactly battery, and the continual mileage that improve pure electric automobile just must adopt the storage battery of High Performance and capacity, and then the cost of electronlmobil can improve further.Like this, contradiction is created between continual mileage and cost, improve mileage and will increase cost, thus stroke-increasing electric automobile arises at the historic moment, by increasing a set of auxiliary power unit on pure electric automobile, effectively can extend the continual mileage of pure electric automobile, effectively limit again the increase of cost, and auxiliary power unit also become another study hotspot of electronlmobil field simultaneously.At present, using maximum in auxiliary power unit is small-sized piston formula driving engine, and piston engine is due to reciprocating motion of the pistons, Power output has cyclic fluctuation, simultaneously, can torsion oscillations be produced in Power output process, easily cause auxiliary power unit power system to resonate or premature fatigue destruction.
Summary of the invention
For prior art Problems existing, the present invention proposes a kind of auxiliary power unit for electric vehicle, by installing auxiliary power unit additional in pure electric automobile, effectively extends the continual mileage of vehicle, make again the cost of car load be unlikely to increase too much, be conducive to promoting the use of of electronlmobil.
The present invention proposes a kind of auxiliary power unit for electric vehicle, comprises driving engine, clutch drived disk assy, platen and electrical generator; Clutch drived disk assy is pressed on the flywheel of driving engine by platen, and electrical generator and clutch drived disk assy are mechanically connected, and the mechanical energy of the driving engine of clutch drived disk assy transmission is converted to electric energy and exports.
The invention has the advantages that:
1, a kind of auxiliary power unit for electric vehicle provided by the present invention, for pure electric automobile provides auxiliary power source, can significantly improve the continual mileage of electronlmobil, effectively limits again the increase of vehicle cost;
2, a kind of auxiliary power unit for electric vehicle provided by the present invention, driving engine always works in generating operation mode, and is optimized driving engine, improves efficiency, reduces discharge.
3, a kind of auxiliary power unit for electric vehicle provided by the present invention, employs clutch drived disk assy in power system, reduces the vibration in power transmission process, avoid the resonance of auxiliary power unit driving system, relax and impact, reduce noise, improve the life-span of auxiliary power unit.
4, the clutch drived disk assy of a kind of auxiliary power unit for electric vehicle provided by the present invention, the adopting by equivalent clutch drived disk assy of orthodox car dry type clutch, and platen is only clutch drived disk assy frictional transmission provides positive pressure, structure is simple, time-to-market can be shortened to a great extent, reduce system development costs.
5, a kind of auxiliary power unit for electric vehicle provided by the present invention can also solve the refrigeration and heating problem of electronlmobil, and may be used for the occasion of emergency service.

In figure: 1-driving engine; 2-engine flywheel; 3-platen; 4-clutch drived disk assy; 5-electrical generator.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
The invention provides a kind of auxiliary power unit for electric vehicle, as shown in Figure 1, mainly comprise driving engine 1, platen 3, clutch drived disk assy 4 and electrical generator 5.
Described driving engine 1 is traditional combustion engine, as spark ignition engine, diesel engine or other engine fuels, is the main power source of auxiliary power unit for electric vehicle, is mechanically connected with clutch drived disk assy 4 and platen 3.
Described clutch drived disk assy 4 transmits the power of driving engine by friction, relax and impact, and avoids resonance, is mechanically connected with platen 3 and electrical generator 5.Described clutch drived disk assy 4 adopting by equivalent orthodox car dry type clutch clutch drived disk assy, all parts are all existing ripe parts, and production technology, equipment, mould etc. are all existing maturations, therefore, greatly can shorten the time-to-market of auxiliary power unit, reduce cost of development.
Described clutch drived disk assy 4 is the same with orthodox car dry type clutch clutch drived disk assy, containing torsion damping parts, there is the effect of torsion damping, decrease the vibration in power transmission process, the resonance of auxiliary power unit driving system can be avoided, relax and impact, reduce noise, improve the life-span of auxiliary power unit.
Clutch drived disk assy 4 is pressed on the engine flywheel 2 of driving engine 1 by described platen 3, and like this, on the friction lining of clutch drived disk assy 2, just effect has positive pressure, and therefore, the function and structure of platen 3 is all fairly simple, and multiple mechanical mode can be adopted to obtain.
Described electrical generator 5 is mechanically connected with clutch drived disk assy 4, and the mechanical energy of the driving engine 1 transmitted by clutch drived disk assy 4 is converted to electric energy and exports.
The invention provides a kind of auxiliary power unit for electric vehicle, driving engine 1 is traditional combustion engine, be that mechanical energy exports by the converts chemical energy of fuel, because platen 3 is pressed on clutch drived disk assy 4 on the engine flywheel 2 of driving engine 1, and have larger friction coefficient between the engine flywheel 1 of clutch drived disk assy 4 and driving engine 1 and platen 3, so just the mechanical energy that driving engine 1 exports is passed to clutch drived disk assy 4, again after clutch drived disk assy 4 vibration damping, pass to electrical generator 5, by electrical generator 5, the mechanical energy that driving engine 1 exports is become electric energy to export, this electric energy then may be used for driving electric automobile during traveling.
The invention provides a kind of auxiliary power unit for electric vehicle, can be used on stroke-increasing electric automobile, only need, by cable, generator output is connected to motor controller, be not mechanically connected with wheel, can according to the actual parts deployment scenarios of electronlmobil, carry out mounting arrangements, therefore mounting arrangements is flexible.
