Fig. 2 is the circuit diagram of the auxiliary meshing type starter of prior art, the type auxiliary meshing type starter comprises direct current generator 1, magnetic switch 3 and control relay 12, coil in current auxiliary meshing type starter magnetic switch all is comprised of a sucking coil and hold-in winding, the number of turn of two coils is substantially equal, and head end links together, be magnetic switch 50 ends, the tail end of sucking coil is connected the tail end bonding of hold-in winding with the power end of direct current generator (being the main contact output wiring terminal of magnetic switch).
Because sucking coil resistance is less, it as voltage rating, is the starter motor of 24V, its resistance generally is about 100 milliohms, so starter motor can little moment of torsion slow-speed before magnetic switch main contact closure, thereby while allowing actuation gear be against on the flywheel ring gear end face, actuation gear can slowly rotate, fork apical tooth state, engaging-in engine flywheel gear ring; After engaging-in gear ring, the magnetic switch main contact just can be closed, in motor, just has large electric current and flow through, and starter motor is just understood high pulling torque output, thereby avoid the generation of starter motor mill teeth fault.Therefore this class starter motor is also referred to as soft engaging starter.
Because the soft engagement moment of this class starter motor is limited, in some cases, actuation gear can't engaging-in gear ring, thereby produces the apical tooth phenomenon.Because actuation gear can't engaging-in flywheel ring gear, sucking coil is forced to long-time energising, and the electric current in coil is larger, the magnetic switch of auxiliary meshing type starter easily produces and burns fault like this, the generation of the faults such as if ignition key adhesion or driver's misoperation can cause commutator to get rid of row, and one-way element is stuck.
Because the sucking coil of this class starter relay and the head end of hold-in winding connect together, in order to guarantee magnetic switch, reliably cut off the power supply, the effective turn of sucking coil and hold-in winding must be basically identical, and the number of turn of hold-in winding can not be very little, so the number of turn of sucking coil is also more.Although can be by the wire diameter of suitable increase sucking coil, and the method for the minimizing sucking coil number of turn, starter motor can slowly be rotated before the magnetic switch main contact is not closed, it is too many that but the number of turn of sucking coil can not reduce, otherwise, the consideration magnetic switch is reliably cut off the power supply, and the number of turn of hold-in winding also needs significantly to reduce.Because the electric current in sucking coil is larger, and the number of turn of sucking coil is more, and the electromagnetic force that causes magnetic switch to produce is larger, causes actuation gear to act on the active force of flywheel ring gear end face excessive, causes the infringement of gear ring end face serious.To act on the active force of flywheel ring gear end face excessive due to actuation gear in addition, during apical tooth, causes the resisting moment of actuation gear transmission larger, and starter motor easily produces apical tooth, and long-time apical tooth easily causes magnetic switch to produce the fault of burning.

Embodiment
In order to make those skilled in the art can further understand feature of the present utility model and technology contents, refer to following about detailed description of the present utility model and accompanying drawing, yet appended accompanying drawing only provide with reference to and explanation use, not be used for to the utility model limitr in addition.
Followingly according to Fig. 3, one embodiment of the invention are described, Fig. 3 is the circuit diagram of the auxiliary meshing type starter with protective function of embodiment of the present invention 1.The structure of the auxiliary meshing type starter with protective function of the present invention is roughly similar to auxiliary meshing type starter structure shown in Figure 1, still mainly reducing gear, direct current generator, engaging mechanism, consists of.Magnetic switch 3 is basic identical with common auxiliary meshing type magnetic switch structure, still adopts pair of contact to control the break-make of the large electric current of direct current generator.Control relay 12 increases the break-make of protective circuit 38 control relay coil L3; realize the break-make of sucking coil L1 and the hold-in winding L2 of magnetic switch 3; the number of turn of two coils is substantially equal; and head end links together; be 50 ends of magnetic switch; the tail end of coil L1 is connected the tail end bonding of coil L2 with the power end of direct current generator (being the main contact output wiring terminal of magnetic switch).Protective circuit realizes the break-make of coil L3 by transistorized conducting and cut-off.
Protective circuit is comprised of two control loops, and control loop one mainly is comprised of resistance R 1, resistance R 2, capacitor C 1, triode Q2, voltage-stabiliser tube DW1, resistance R 3, triode Q1, diode D2; The collector electrode of triode Q1 is connected to 31 ends, and the base stage of Q1 is connected to the collector electrode of triode Q2 and an end of resistance R 3, and the emitter of Q1 is connected to the tail end of coil L3.
Control loop two mainly is comprised of resistance R 4, resistance R 5, capacitor C 2, triode Q3, voltage-stabiliser tube DW2, resistance R 6, voltage-stabiliser tube DW3, capacitor C 3, resistance R 7, resistance R 8, power tube Q4; The D of power tube Q4 is terminated at the tail end of coil L3, and the S of Q4 is terminated at 31 ends, and the G of Q4 is terminated at the collector electrode of triode Q3.
In control loop one and control loop two, adopt delayed-breaking-off function.The ignition switch closure, provide a voltage to starter motor, and control loop one detects the voltage of 30b end simultaneously, if the voltage of 30b is greater than the value (as 5V) of setting, control loop one quits work.Simultaneously in control loop two, the DW3 in mu balanced circuit reaches its breakdown voltage and conducting is started working control loop two, triode Q4 conducting, control relay 12 conductings, thereby magnetic switch 3 conductings, the electric current of this control relay can, simultaneously by two triode Q1 and Q4, arrive 31 ends.If the voltage of 30b is less than the value (as 5V) of setting, control loop two is not worked always, and triode Q4 is in cut-off state, and namely the electric current of relay can only pass through triode Q1.When current"on"time, arrive the value of setting (after as 0.1～7s), voltage regardless of the 30b end, triode Q1 ends, the coil of control relay 12 opens circuit, control relay 12 quits work, the sucking coil of magnetic switch 3 opens circuit, and starter motor can be avoided the generation of apical tooth fault effectively like this, has guaranteed the reliability of starter motor engagement.When control loop two was started working, through a set time (7-30s) afterwards, control loop two was controlled this control relay 12 and is disconnected, and can avoid thus burning due to the switch that the long-time energising of magnetic switch causes the generation of fault.
In conjunction with Fig. 3, the working procedure of the auxiliary meshing type starter with protective function of said structure is: when starter motor is started working, 35 connect, the 50c of relay holds electricly, the Q1 of control loop one in relay, the Q2 conducting, coil L3 energising, the contact adhesive, 50 ends of magnetic switch 3 obtain electric, coil L1 and the coil L2 of magnetic switch 3 switch on simultaneously, the electromagnetic force of two coil generations makes plunger move towards the contact direction, the direct current generator that in coil L1, electric current passes through, due to this electric current much larger than the starter motor no load current, direct current generator starts slowly to rotate, the rotation of drive actuation gear, meanwhile plunger makes actuation gear move towards flywheel ring gear by pull-fork assembly, actuation gear is in the situation that slow-speed completes flexible engagement with flywheel ring gear, then under the effect of plunger, to contact with magnetic switch 3 main contacts be the main contact closure of magnetic switch 3 to movable touching plate, coil L1 is by short circuit, the voltage of 30b end raises, the breakdown voltage that reaches voltage-stabiliser tube DW3 when voltage makes the DW3 conducting, make control loop two work, and magnetic switch main contact closure now, in direct current generator, there is large electric current to pass through, start full moment of torsion output, make engine start.The time of the control loop delay cut-off of control coil L2 is grown (as being greater than 7s), can when hold-in winding is forced to switch on for a long time, realize forcing outage, and magnetic switch discharges, and drives return, and starter motor quits work.
Control loop one employing delay cut-off design due to the control relay protective circuit, like this under abnormal conditions, as actuation gear and flywheel ring gear gear pair, do not mate or apical tooth etc. occurs, actuation gear can't engaging-in flywheel ring gear, cause the magnetic switch main contact can't be closed, sucking coil is forced to long-time large electric current while passing through, delay control circuit in control loop one disconnects, Q1 by, by the voltage that detects the 30b end, do not meet requirement is set, not conducting of Q4, sucking coil and hold-in winding are forced outage, thereby can prevent effectively that magnetic switch from burning the generation of fault.
Because the control loop two of controlling hold-in winding adopts the time delay design, if what ignition switch 35 continued is kept closed, the maintenance "on" position that makes motor continue, after certain hour (as 7-30s), control loop two can disconnect motor by force, can not pass through for a long time electric current in hold-in winding, can prevent effectively that hold-in winding from burning the generation of fault, can prevent from equally getting rid of row due to the commutator that ignition key adhesion or driver's misoperation cause the generation of the fault such as one-way element is stuck.
Fig. 4 is the circuit theory diagrams of the auxiliary meshing type starter with protective function of another embodiment of the present invention, and this mode of execution and mode of execution 1 are basic identical, and unique different place is, control loop two does not adopt delay circuit.Part for identical, repeat no more here.Below only with regard to different parts, set forth.
After proceed-to-send, 35 disconnect, the 50c end outage of relay, control loop two voltage-stabiliser tube DW3, power tube Q3 all end, and in solenoid winding L2, no current flows through, and the electromagnetic force that magnetic switch produces disappears, magnetic switch sound contact separates under the effect of return spring, the direct current generator outage, starter motor quits work, and actuation gear is got back to reset condition.
In the above embodiments of the present application, protective circuit is comprised of two control loops, but is not limited in this.These two control loops only are used for illustrating the working principle of protective circuit, not are used for limiting this protective circuit.Within the identical and loop that can play control of any principle with the embodiment of the present application all is included in scope of the present utility model.Simultaneously, the present embodiment has comprised control loop one and control loop two simultaneously, wherein arbitrary but those skilled in the art can select according to actual needs, or selects other can realize controlling the loop of function.
Certainly; the present invention also can have other various embodiments; in the situation that do not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art are when making according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
