Description
Technical field
The utility model relates to a kind of extended-range electric vehicle fuel engines and electrical generator connection structure of leaning on the fuel oil generating to increase the continuation of the journey mileage.
Background technology
At present, the battery-driven car in the industry generally adopts accumulator jar to supply power to drive motor, and then drives the wheel running, reaches the purpose that electric-only mode goes.But because of the finite capacity of accumulator jar, once electrically-charged continuation of the journey mileage is limited too; In addition because the accumulate technology of accumulator jar receives the influence of temperature height bigger: when summer, temperature on average 30 was spent, the reserve of electricity of accumulator jar will descend about 40% when temperature is lower than zero degree in the winter time, moreover; Battery-driven car in use; Run into the accumulator jar electric weight when not enough through regular meeting, the user takes the phenomenon that continues to go in order to reach the goal, causes the storage battery power shortage; Cause accumulator jar often to be in the deep discharge state, shortened about 30% the service life of accumulator jar.
For this reason, also there is the dealer to adopt accumulator jar is connected with electrical generator to the accumulator jar serial connection charge, satisfy the continuation of the journey demand.No matter be the small power generation unit or be to utilize the clutch end direct mount electrical generator of fuel engines bent axle to come to charge mostly to accumulator jar by the fuel electric generator that fuel engines and electrical generator are formed.When the electrical generator of this mounting means was directly installed on the bent axle, the centering of generator shaft all relied on the crankshaft bearing location of driving engine.Like this; Just there is bigger defective: the one, because generator shaft and engine shaft are the one state; Be to keep certain distance between the center-point of position and generator amature of fulcrum with the engine crankshaft bearing; The output shaft of this segment distance is because its steel self characteristics and the concentricity tolerance that adds man-hour can make the position of stationary power generation machine rotor on the engine output shaft phenomenon that beat is beated occur unavoidably.Even processing accurately again, it also is normal that the beat that 0.03 millimeter occurs is beated.The 2nd, generator casing and driving engine bonded assembly casing are in and also have certain radially cumulative limit in the course of processing.The 3rd, the rotor of electrical generator and stator are silicon steel plate punch forming part, equally also occur the radial tolerance size unavoidably.Therefore, the processing of bent axle, driving engine is connected with the shell of electrical generator and the links such as processing of rotor and stator all can't be avoided cumulative limit.When electrical generator is installed, guarantee the centrad of rotor in stator, difficulty is very big.
Current, the insider often adopts the way that strengthens the gap between generator amature and the stator to solve beat and beats to the damage of electrical generator under above-mentioned situation, making the electrical generator can normal operation.But well-known: the generating efficiency of electrical generator and stator and gap between rotor have confidential relation, and also promptly, the gap is big more, and the generating efficiency of electrical generator is just low more, otherwise, high more.Even more serious is: in installation process, the eccentric excessive of rotor and stator appears in careless slightly meeting, causes the friction rotor stator, and electrical generator is damaged, and can't use.
The highly effective permanent-magnet electrical generator of widespread use especially in recent years; The periphery of its rotor is inlaid with the polylith permanent magnetic tile; Permanent magnetic tile is adding the thickness deviation that can occur trace man-hour equally, and permanent magnetic tile is frangible in addition, and antioxygenic property is relatively poor; For improving the antioxygenic property of permanent magnetic tile, be provided with zinc coating on its surface.If, will cause damage in case stator occurs and the rotor Concentricity tolerance causes friction rotor stator phenomenon.
Even if when mounted through careful debugging, make one side minimum clearance of rotor and stator reach minimum requirement, in using for a long time, the thermal deformation of bent axle and engine case can not guarantee fully that the monolateral minimum clearance of rotor and stator does not change.If slight wearing clearance appears in crankshaft bearing, can cause the damage of electrical generator equally, shorten the service life of electrical generator.
Summary of the invention
The purpose of the utility model is to provide a kind of to need to increase an alignment bearing and solve the generator shaft beat jumping phenomena that difference size on business causes; Improve the load and the resistance to abrasion of engine crankshaft again; Prolong the service life of electrical generator, improve the extended-range electric vehicle fuel engines and the electrical generator connection structure of generator for electricity generation efficient.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of extended-range electric vehicle fuel engines and the electrical generator connection structure of the utility model; The shell of fuel engines output shaft position is captiveed joint fuel engines output shaft and generator amature cross-under with the electrical generator end housing of generator casing.On the housing of described electrical generator end and be equipped with between the fuel engines output shaft and be used for fixing generator casing, stator coil and the fuel engines output shaft keeps concentric location bearing.
Because adopt technique scheme, the beneficial effect of the utility model is: the utility model is through at installing and locating bearing on the housing of electrical generator end and between the fuel engines output shaft.Greatly reduce the installation difficulty of electrical generator, the engine output shaft decentraction beat jumping phenomena of having avoided difference size on business to cause; Can reduce the tolerance clearance of generator amature and stator, improve the generating efficiency of electrical generator.The load and the resistance to abrasion of bent axle have been increased simultaneously greatly.Reduce cost of installation, reduced the damage of electrical generator, prolonged the service life of electrical generator.
