Detailed description of the invention
Fig. 1 is the increasing journey for electric vehicle of the individual motor formula with torsional vibration damper according to one embodiment of the utility model
The structural schematic diagram of device.
Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail, it is to be understood that this is practical
Novel protection scope 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, according to the electronic vapour of individual motor formula with torsional vibration damper of the preferred embodiments of the present invention
The specific structure of automobile-used distance increasing unit includes: engine 1, flywheel 2, torsional vibration damper 3, flywheel shell of engine 4 and generator.Its
In, the power output end of engine 1 is coaxially fixedly linked through flywheel and torsional vibration damper 3, the electricity of torsional vibration damper 3 and generator
Machine rotor 6 is coaxially fixedly linked, so that the individual motor formula increasing for electric vehicle with torsional vibration damper with torsional vibration damper
The motor of journey device is connected to the scheme of engine output end by torsional vibration damper, and overall structure is more compact, convenient for disassembly and assembly, even
Stable structure is connect, substitutes electromagnetic clutch with torsional vibration damper, engine start/stop impact is reduced, does not need dedicated for power generation
Coil windings can also reduce starter and flywheel ring gear on engine, can effectively reduce 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
