Background technique
Energy conservation and environmental protection are the eternal themes of automotive field, it is known that pure electric automobile is by current driving force battery specific energy
Smaller, the factors such as price is high influences, continual mileage are not able to satisfy remote trip, and there are mileage cokes to pure electric automobile by the people
Consider.Distance increasing unit can effectively solve pure electric automobile mileage anxiety problem, have become new-energy automobile development trend.Distance increasing unit one
As by engine+generating set at.
Wherein, the crankshaft of engine is connected to motor by an electromagnetic clutch, be exactly using motor by electromagnetism from
Clutch is connected on engine, although electromagnetic clutch is integrated into generator amature component in length no advantage that remains unchanged,
And the cost of electromagnetic clutch is higher than friction plate clutch.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
Summary of the invention
The purpose of the present invention is to provide a kind of simple and reasonable individual motor formula distance increasing units for electric vehicle, this is solely
The motor of vertical electric motor type distance increasing unit for electric vehicle passes through the scheme that hard connecting mode is connected with engine output end, overall structure
More compact, convenient for disassembly and assembly, connection structure is stablized, and cost is lower.With Hard link substitute electromagnetic clutch, do not need dedicated for
The coil windings of power generation can also reduce starter and flywheel ring gear on engine, can effectively reduce cost.
To achieve the above object, the present invention provides a kind of individual motor formula distance increasing units for electric vehicle, comprising: starts
Machine, crankshaft one end is power output end, and is provided with flywheel, passes through the outside output power of the flywheel；The outside of the flywheel
It is provided with flywheel shell of engine；Connecting flange is coaxially fixedly linked with the flywheel；And generator includes: electric machine casing, electricity
Machine rotor and motor stator, the electric machine casing are fixedly linked with flywheel shell of engine, and the rotor and connecting flange are same
Axis is fixedly linked；The motor stator is fixed on the inner wall of electric machine casing and coaxial with rotor.
In a preferred embodiment, rotor is connect with connecting flange rigid coaxial.
Compared with prior art, individual motor formula distance increasing unit for electric vehicle according to the present invention has following beneficial to effect
Fruit: the motor of the individual motor formula distance increasing unit for electric vehicle passes through the scheme that hard connecting mode is connected with engine output end,
Overall structure is more compact, convenient for disassembly and assembly, and connection structure is stablized, and cost is lower.Electromagnetic clutch is substituted with Hard link, is not needed
Dedicated for the coil windings of power generation, the starter and flywheel ring gear on engine can be also reduced, can be effectively reduced cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of individual motor formula distance increasing unit for electric vehicle according to an embodiment of the present invention.
Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1, the specific knot of individual motor formula distance increasing unit for electric vehicle according to the preferred embodiment of the present invention
Structure includes: engine 1, flywheel 2, connecting flange 3, flywheel shell of engine 4 and generator.Wherein, the power output end of engine 1
It is coaxially fixedly linked through flywheel and connecting flange 3, connecting flange 3 and the rotor 6 of generator are coaxially fixedly linked, so that should
The motor of individual motor formula distance increasing unit for electric vehicle passes through the scheme that hard connecting mode is connected with engine output end, whole to tie
Structure is more compact, convenient for disassembly and assembly, and connection structure is stablized, and cost is lower.Electromagnetic clutch is substituted with Hard link, does not need specially to use
In the coil windings of power generation, the starter and flywheel ring gear on engine can be also reduced, can be effectively reduced cost.
Specifically, the crankshaft of engine 1 is most important component in engine.It bears the power that connecting rod transmits, and will
It is changed into torque and is exported by crankshaft and other attachmentes on engine is driven to work.Crankshaft by gyrating mass centrifugal force,
The gas inertia power of mechanical periodicity and the collective effect of reciprocal inertia force make crankshaft bear the effect of flexion torsion load.Therefore
It is required that crankshaft has enough strength and stiffness, journal surface need are wear-resisting, work is uniform, balance is good.Crankshaft one end of engine 1
For power output end, and it is provided with flywheel 2, passes through the outside output power of flywheel 2.The outside of flywheel 2 is provided with engine and flies
Wheel shell 4.
Connecting flange 3 and the flywheel 2 of 1 power output end of engine are coaxially fixedly linked.
Generator includes: electric machine casing 5, rotor 6 and motor stator 7, wherein electric machine casing 5 and engine flywheel
Shell 4 is fixedly linked, and rotor 6 is coaxially fixedly linked with connecting flange 3；Motor stator 7 is fixed on the inner wall of electric machine casing 5
And it is coaxial with rotor 6.The generator as electric motor starting engine is played can not need that individual starter is arranged,
Cost and arrangement space are saved.
When vehicle driving, engine 1 is permanently affixed to best efficiency point and works, and output power is kept constant, power
It is transmitted to rotor 6 by flywheel 2, connecting flange 3 and generates electricity；When the electricity abundance of Vehicular battery, engine 1 stops
Machine；When Vehicular battery not enough power supply, rotor 6 just will drive the starting of engine 1, charge the battery.This architecture
Advantage are as follows: design of part is simpler, and fault point is few, and space ruler is more very little small, and cost is lower.
To sum up, the motor of the individual motor formula distance increasing unit for electric vehicle passes through hard connecting mode and engine output end phase
Scheme even, overall structure is more compact, convenient for disassembly and assembly, and connection structure is stablized, and cost is lower.Electromagnetic clutch is substituted with Hard link
Device does not need the coil windings dedicated for power generation, can also reduce starter and flywheel ring gear on engine, can be effectively reduced
Cost.
The aforementioned description to specific exemplary embodiment of the invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining specific principle of the invention and its actually answering
