Description
Technical field
The utility model relates to the improvement technology of motorcycle ignition system, is specifically related to a kind of motorcycle speed-limiting ignitor.
Background technique
The function of motorcycle ignition system is that the low tension that generator is exported is become high-tension electricity, on time high-tension electricity is distributed to spark plug by the job order of motor and is produced electrical spark, lights compressed inflammable mixture, makes it the work done of burning.For the motor of high rotating speed, high compression ratio, adopt traditional touch igniting system that has to be difficult to adapt to.Therefore, the normal solid-state ignition system of forming by ignition, spark coil and spark plug etc. that adopts.Traditional ignition work can be divided into three processes: the discharge of the charging of capacitor C, the triggering and conducting of controllable silicon SCR and capacitor C.But these igniting are function singleness.Some motorcycle riders are liked driving a car violently, and when speed reaches very high, also are difficult to the artificial control speed of a motor vehicle even pinpoint the problems, and so very easily cause traffic accident.Therefore, need speed limiting mechanism be set to motorcycle usually, as Chinese patent CN03268388X disclosed " motorcycle speed-limiting device and speed-governing igniter " etc.But these speed limit ignition mechanism component are more, complex structure, thereby cost is higher; Simultaneously, ignition performance is relatively poor during the speed limit ignition mechanism lower-speed state that has, can not satisfy the demand in market.
The model utility content
At the prior art above shortcomings, it is a kind of simple in structure that the purpose of this utility model is to provide, and cost is low, and the motorcycle speed-limiting ignitor of reliable performance.
The purpose of this utility model is achieved in that a kind of motorcycle speed-limiting ignitor, comprise diode D, capacitor C, controllable silicon SCR, spark coil L and spark plug T, it is characterized in that diode D, capacitor C and spark coil L connect successively, the secondary spark plug T that connects of spark coil L; The magnetogenerator charge coil connects the positive pole of diode D; The anode of controllable silicon SCR is connected between the negative pole and capacitor C of diode D, the minus earth of controllable silicon SCR; The controllable silicon SCR control utmost point connects the output terminal of ignition control circuit, and the input end of ignition control circuit connects the trigger winding of magnetogenerator; The input end of ignition control circuit is in parallel with restriction control circuit one end, the other end ground connection of restriction control circuit.
When magnetogenerator charges to capacitor C, the rotating speed trigger signal is given tach signal of controllable silicon SCR, if the rotating speed trigger signal is less than setting value, then controllable silicon SCR conducting this moment, after leading ground, capacitor C charging left end discharges, the capacitor C right-hand member balance of also discharging rapidly produces electrical spark by the spark coil L back of boosting; If magnetogenerator trigger winding trigger signal is greater than setting value, then not conducting of controllable silicon SCR this moment, the capacitor C left end is not led ground, the discharge igniting coil does not produce electrical spark, and igniter is not worked.
The utility model can reduce the accident generation that causes because of the hypervelocity of driving a car violently effectively the high speed control of motorcycle in the scope of setting, not only simple in structure, cost is low, and reliable performance has satisfied the market demand.

Embodiment
As shown in Figure 1, a kind of motorcycle speed-limiting ignitor, mainly be made of diode D, capacitor C, controllable silicon SCR, ignition control circuit, restriction control circuit, spark coil L and spark plug T, diode D, capacitor C and spark coil L connect successively, the secondary connection spark plug T of spark coil L.The induction Ac that magnetogenerator sends, its electric current charges to capacitor C through commutation diode D, in capacitor C, the terminal voltage of capacitor C is raise (as reaching 300-400V) rapidly electrical power storage.For the terminal voltage that guarantees capacitor C reaches rating value, the capacitance of general ignition is about 1 μ F.The anode of controllable silicon SCR is connected between the negative pole and capacitor C of diode D, the minus earth of controllable silicon SCR; The controllable silicon SCR control utmost point connects the output terminal of ignition control circuit, and the input end of ignition control circuit connects the trigger winding of magnetogenerator; Restriction control circuit one end is in parallel with the input end of ignition control circuit, the other end ground connection.Controllable silicon SCR is the electronic switching element of ignition.When the magnetogenerator flywheel forwarded ignition location to motor, the positive pulse electric current of magnetogenerator trigger winding provided trigger current to the SCR control utmost point on time by ignition control circuit, makes the controllable silicon conducting.In the moment of controllable silicon SCR triggering and conducting, the electric energy that capacitor C is stored discharges rapidly to the primary air of spark coil through controllable silicon SCR anode and negative electrode, thereby on secondary winding, respond to high-tension electricity, make spark plug produce electrical spark, light compressed inflammable mixture, make it the work done of burning.The utility model since in the input end parallel connection of ignition control circuit the restriction control circuit, if magnetogenerator trigger winding (rotating speed) trigger signal is greater than setting value, ground is not led in then not conducting of controllable silicon SCR this moment, capacitor C left end, the discharge igniting coil does not produce electrical spark, and igniter is not worked; Therefore can realize the speed limit igniting of motorcycle.Ignition control circuit adopts the existing conventional circuit, rate-limiting control circuit adopt as shown in Figure 2 circuit or similarly equivalent circuit get final product.
Its working principle is: magnetogenerator charges to capacitor C, the rotating speed trigger signal is given tach signal of controllable silicon SCR, if the rotating speed trigger signal is less than setting value, then controllable silicon SCR conducting this moment, after leading ground, electric capacity charging left end discharges, the capacitor C right-hand member balance of also discharging rapidly produces electrical spark by the spark coil L back of boosting; If the rotating speed trigger signal is greater than setting value, then not conducting of controllable silicon SCR this moment, the capacitor C left end is not led ground, is not discharged, and spark coil does not produce electrical spark, and igniter is not worked.
