Abstract
The utility model provides an AC constant voltage generator for a small four-wheel tractor, which is additionally with an adjusting rotor, a return spring and two centrifugal devices on the AC generator of a common small four-wheel tractor, wherein the return spring is installed on a track block of the centrifugal device arranged on the end surface of the adjusting rotor, and the other end of the return spring is installed on a bracket of the centrifugal device. When an engine rotates at an idle speed, the generator outputs a rated voltage. When the engine rotates at a high speed, a track wheel of the centrifugal device pushes the track block of the centrifugal device to drive the adjusting rotor to deviate from a maximum generating position under the action of centrifugal force. However, when the rotation speed of the engine rises, the engine can also output the rated voltage.
Description
The utility model relates to a kind of improved alternating current generator, and particularly a kind of tractor with small four wheels exchanges constant voltage generator.Rated output power 90W, rated voltage 12V.
Existing tractor with small four wheels alternating current generator mainly is made up of belt pulley, shell, stator, rotor, generator shaft and bearing.The tractor with small four wheels alternating current generator of selling on the market is exactly this form.When belt pulley slowly ran, generator got final product output LOW current and low-voltage, and when the belt pulley high speed rotating, generator can be exported rated current and voltage.Because the operational environment of tractor with small four wheels often is in day and night, be very important for the use of tractor with small four wheels electric elements so prepare a generator.When tractor with small four wheels was driven a vehicle at night, often need the illumination or the illumination of turning, but because the electric current of present tractor with small four wheels alternating current generator is relevant with the rotating speed of tractor with small four wheels engine with voltage, along with the raising of pulley speed, current/voltage also increases.When the tractor with small four wheels low engine speed is rotated (as, meeting, turning, climbing, descending) electric current and the voltage of generator output is lower than rated value, the brightness of illumination deepening, bring sense of insecurity for the driving of tractor with small four wheels, the traffic accident that frequent appearance brings inadequately because of brightness of illumination causes unnecessary economic loss to the country and people's life.
Task of the present utility model is to provide a kind of improved tractor with small four wheels to exchange constant voltage generator, when it can or be run at high speed at tractor with small four wheels low speed, and output rated voltage.
Task of the present utility model is finished as follows: generator amature is made two parts, a part is fixed on the generator shaft, another one is installed on the generator shaft, but can rotate around the axis, its corner is 0～30 degree, hold out against by the sedimentator rail wheel, this part rotor can not be moved vertically, be welded with two symmetrical sedimentator rail blocks on the right side of this part rotor, two symmetry orbital wheels of sedimentator can roll on the sedimentator rail block, to promote regulating rotor rotation, reach the purpose of pressure regulation.Sedimentator is made up of two parts, each several part all can rotate around the sedimentator rotating shaft, when engine is in idling mode under action of centrifugal force, belt pulley is in minimum speed, at this moment, fixed rotor and adjusting rotor are in the maximum generating watt position, and output voltage can reach 12V, when tractor with small four wheels travels, engine speed raises, and generator pulley is also accelerated thereupon, and this moment, sedimentator was started working.Under action of centrifugal force, sedimentator rotates around the sedimentator rotating shaft, the sedimentator rail wheel promotes the sedimentator rail block, make the adjusting rotor rotation, depart from maximum generating watt position (being fixed rotor magnetic field and the part payment of adjusting rotor field), but because the rotating speed of fixed rotor and adjusting rotor raises, generator output voltage still keeps 12V constant.When the generator pulley rotating speed reduced, sedimentator centrifugal force reduced and under the effect of return spring, made to regulate rotor and be returned to the maximum generating watt position gradually, so just reached the purpose of tractor with small four wheels output rated voltage at low speed or when running at high speed.
The utility model also can be realized in the following way: promptly the sedimentator part is constant, changes the structure of rotor, is the box-like structure of inside and outside magnetic knot by original internal magnetization structural change, adopts this structure that the generator volume is reduced, and its voltage-regulation principle is ditto described.
The utility model also can be realized in the following way: rotor is fixedlyed connected with copper sheathing, copper sheathing is connected with the generator axle key, can not sway, but can move along axis direction, steel bushing and rotor are integrally welded, when engine is in idling shape speed, under the effect of return spring, rotor is in the maximum amount of starting position, promptly defeated moving voltage 12V, when engine speed raises, centrifugal BOB(beginning of block) work is dialled the angle under action of centrifugal force, is stirred steel bushing and move along axis direction for centrifugal, make rotor depart from the maximum generating watt position, but because the rotating speed of rotor raises, still exportable voltage 12V, centrifugal centrifugal force reduces and under the effect of return spring when engine speed reduces, make the rotor be returned to the maximum generating watt position gradually, so just reached the purpose of tractor with small four wheels output rated voltage 12V or when running at high speed at low speed.
The utility model is made simple, and is easy to use, and output rated voltage in the time of can or running at high speed at tractor with small four wheels low speed is so avoided original tractor with small four wheels alternating current generator can not be with the shortcoming of road speed and engine speed automatic Regulation.
