Background technology
The integral type starter concurrently engine of current car is because drive the torque demand needed during engine very large, therefore the little air displacement car type of below 150cc can only be applicable to, if for the machine being applied in more than air displacement 150cc, the performance of integral type starter concurrently engine just must be increased.The current practice increases the magnetic of generator rotor magnet or increases the relativity area of rotor and stator, but these ways will cause needing during engine running the magnetic resistance between the extra rotor weight of burden or rotor and stator.
In order to integral type starter concurrently engine can be made to start more than 150cc engine, increase generating capacity when to increase high rotating speed after driveability also and the extra rotor weight increased, also produce more multiple generator magnetic resistance, thus reduce engine performance.

Embodiment
Understand for the ease of persons skilled in the art and realize the utility model, now describing embodiment of the present utility model by reference to the accompanying drawings.
The structural representation of the generator 1 that Fig. 1 system a kind of inertia of the present utility model is variable, this generator 1 is mounted on to be had on an engine of a bent axle, and comprise a generator amature 11, this generator amature 11 has the generator amature group of magnets be made up of a plurality of generator amature magnet 12, and this generator 1 has more a generator unit stator 13 in addition.Wherein this generator amature 11 drives by this bent axle and rotates along a center, and this generator unit stator 13 maintains static, and therefore forms relativity and produces induced electromotive force, making this generator 1 produce electric power.Illustrate in greater detail, when this generator amature 11 rotates, these generator amature magnet 12 also rotate together along with this generator amature 11 and act on this generator unit stator 13 and produce induced electromotive force.Wherein, this generator 1 is preferably integral type starter concurrently engine.
In a preferred embodiment, this generator amature 11 is all circle with this generator unit stator 13, and further, this generator amature 11 is all a loop configuration with this generator unit stator 13, and these center has a circular hollow structure.Wherein, this circular hollow structure this generator unit stator 13 coated of this generator amature 11, namely this generator amature 11 is arranged at the outside of this generator unit stator 13, and can this generator unit stator 13 for rotating in the center of circle.This generator unit stator 13 is fixed with engine, and this bent axle can set firmly with this generator amature 11 and drive this generator amature 11 to rotate.It should be noted that the just citing of above-mentioned structural allocation, not restriction of the present utility model.
In addition, this generator amature group of magnets is better to be made up of 3 generator amature magnet 12, but and non-limiting.These generator amature magnet 12 can become a part for the inertia weight of the flywheel turns of this engine, and each generator amature magnet 12 by one take advantage of mounted mechanism 14 take advantage of carry.These bearing structures 14 can be integral type structure with these rotor magnets 12, and also can be that structure is separately arranged at together, when for integral type structure, these load carriers 14 can be parts for these rotor magnets.These take advantage of one end 15 of mounted mechanism 14 to be fixedly connected on this generator amature 11, therefore these take advantage of mounted mechanism 14 to make these generator amature magnet 12 be driven by this generator amature 11 and together rotate, because these take advantage of the other end 16 of mounted mechanism 14 not have fixing, therefore after the rotation of this generator amature 11 reaches a specific speed, this other end 16 will because of centrifugal force away from this generator unit stator 13, below fixing one end is referred to as stiff end 15, and loose one end is called shift end 16.These stiff ends 15 can have and take advantage of mounted mechanism axle center 17, when reaching specific rotation speeds, these shift ends 16 are subject to centrifugal action and take advantage of mounted mechanism axle center 17 for the center of circle is towards radial rotating to angle with this.
In other words, when generator amature 11 does not rotate or this generator 1 is standby, these take advantage of these shift ends 16 of mounted mechanism 14 to produce displacement, as shown in Figure 1, each generator amature magnet 12 is close to outside this generator unit stator 13, and does not produce displacement.And after generator 1 starts, this bent axle drive electrical generators rotor 11 and these generator amature magnet 12 thereof together rotate, now because rotating speed not yet reaches a specific speed, therefore produced centrifugal force is still not enough to allow these take advantage of the shift end 16 of mounted mechanism 14 to produce radial displacement, and therefore these generator amature magnet 12 are still close to this generator unit stator 13.Above-mentioned setting has an advantage, because this generator 1 is the use of starter at engine start previous crops, therefore these generator amature magnet 12 are set to be the initial condition close to this generator unit stator 13 before not reaching a specific rotation speeds by the utility model, and this state can give full play to the driving force of this generator 1.
Fig. 2 is the variable working state schematic representation of generator 1 when this generator amature 11 reaches a specific rotation speeds of the utility model inertia.After this generator amature 11 starts and reaches a specific rotation speeds, because produced centrifugal force has been enough to allow these take advantage of the shift end 16 of mounted mechanism 14 to produce displacement, therefore as shown in Figure 2, except these stiff ends 15 taking advantage of mounted mechanism 14 are still fixing and close to except this generator unit stator 13, remainder produces radial displacement together with these generator amature magnet 12, and away from this generator unit stator 13.Because the driving force of generator 1 described in the utility model is promoted, its magnet magnetic and magnet active area are all to strengthen, thus the magnetic resistance that after making engine start, this generator produces becomes the burden of engine on the contrary, the magnetic resistance produced between generator unit stator 13 and these generator amature magnet 12 can be made to diminish by the utility model, according to above-mentioned configuration, the effect of saving electricity and producing can be reached.
In addition, generally speaking four impulse strokes of engine are air inlet respectively, compression, blast and exhaust, and its excess-three stroke neither work done except explosion stroke, therefore rotating speed must be maintained by the inertia force of engine flywheel, the weight of these generator amature magnet 12 of the present utility model can be regarded as a part for inertia weight when this engine flywheel is rotated, and the utility model utilizes centrifugal force during high rotating speed these to be taken advantage of the shift end 16 of mounted mechanism 14 to produce displacement and drive these generator amature magnet 12 away from the effect of this generator unit stator 13, to can be considered that flywheel turns diameter is added flywheel turns inertia strength by strengthening, therefore the high rotating speed of engine can be maintained, and larger horsepower can be produced.Preferably, this specific rotation speeds is more than 5000 revs/min (rpm).
In addition, in order to make each one end of mounted mechanism 14 of taking advantage of identical in high-revolving degree of displacement, the increasing degree of this flywheel turns diameter is made to remain identical, the utility model further can arrange a telescopic mechanism 21 each taking advantage of on mounted mechanism 14, a such as elastic mechanism 21, preferably this telescopic mechanism 21 is spring mechanisms 21, one end of this spring mechanism 21 is arranged at this stiff end 15 taking advantage of mounted mechanism 14, the other end of this spring mechanism 21 is arranged at another shift end 16 taking advantage of mounted mechanism 14, each can be made thus to take advantage of mounted mechanism 14 to be subject to affecting each other, and can guarantee when high rotating speed, eachly take advantage of the centrifugal force suffered by mounted mechanism 14 identical and produce the radial displacement of formed objects.
In addition, generator unit stator 13 of the present utility model can arrange a plurality of transducer, preferably these transducers are one group with three rotor angle sensors and a bent axle orientation angle transducer, and be arranged at the position of taking advantage of the stiff end 15 of mounted mechanism 14 close to this on this generator unit stator.This rotor angle perceptron is in order to detect the angle of this generator amature, and this bent axle orientation angle perceptron is in order to detect the absolute angle of a bent axle.If it should be noted that, these transducers are installed near the part of this shift end 16 on this generator unit stator 13, when may take advantage of mounted mechanism 14 displacement because of this and these sensor distance excessive and cause sensing mistake.
Therefore, the generator that the utility model provides a kind of inertia variable, and have generator amature group of magnets can start, await orders or the slow-speed of revolution time close to generator unit stator, therefore larger magnetic resistance and larger electric power is produced, and when high rotating speed, therefore these generator amature magnet away from this generator unit stator, can produce less magnetic resistance to reduce electric power generation, and the larger flywheel turns inertia of generation maintains rotating speed, makes the usefulness of engine to maintain.
Although depict the utility model by embodiment, but those of ordinary skill in the art know, when not departing from spirit of the present utility model and essence, the utility model just can be made to have many distortion and change, and scope of the present utility model is limited to the appended claims.
