Description
Technical field
The present invention relates to a kind of starter motor, particularly a kind of starter motor with second order engagement capability.
Background technique
Starter motor, by the difference of engagement system, mainly contains positively engaging starter motor and flexible engagement starter two kinds.
The topmost feature of positively engaging starter motor is exactly have positively engaging spring in engaging mechanism, when actuation gear gets rear and flywheel ring gear end contact, actuation gear cannot move on, positively engaging spring in engaging mechanism is compressed, and plunger in magnetic switch can be moved on, to connect main contact, big current is passed through in motor, actuation gear is rotated, thus the apical tooth that staggers, engaging-in gear ring.The key point of positively engaging starter motor is positively engaging spring, if this elastic force is not enough, then after the apical tooth that staggers, the underspeed that actuation gear is got, is easy to mill teeth fault occurs.Therefore the elastic force of positively engaging spring is enough large, thus guarantee is staggered, the power of apical tooth rear spring release can make the quick engaging-in gear ring of actuation gear, thus avoids occurring mill teeth fault.Be " 201220453443 " see the patent No., the Chinese utility model patent that name is called " the fixing and sealing configuration of starter motor engage spring and positively engaging starter motor ".
And for powerful starter motor, because its moment is larger, therefore need positively engaging spring force also to design larger, like this, when apical tooth, the gear ring wearing and tearing caused during actuation gear friction gear ring end face can aggravate, after gear ring wearing and tearing, become greatly with the distance of gear, the probability that mill teeth fault can be caused to occur strengthens.So what general powerful starter motor adopted is flexible engagement system.
Without positively engaging spring in flexible engagement starter, after starter motor apical tooth, electric current flows into motor by magnetic switch pull in winding, and this electric current can make motor slow-speed, thus the apical tooth that staggers, enter gear ring.If this slow-speed electric current is less, then the soft engagement moment produced can be less, and possibly cannot stagger the engaging-in gear ring of apical tooth, namely occurs apical tooth fault.If apical tooth overlong time, then pull in winding can burn owing to being energized for a long time.For flexible engagement starter, after appropriate design, its engagement success rate can reach more than 99.7%, and after the more number of times of use, along with the wearing and tearing of gear ring, its apical tooth rate can raise.And for namely stopping the starter motor namely playing system, because start-stop number of times is more, therefore need the projected life of starter motor longer than usual starter motor, need to reach 10 ten thousand to 20 ten thousand times, engagement success rate needs to reach 100%.After repeatedly starting, gear ring there will be wearing and tearing, and flexible engagement moment also has certain decline, can cause occurring apical tooth fault.
For solving unavoidable apical tooth fault, some flexible engagement starters directly increase positively engaging spring in systems in which, and to realizing normal work for flexible engagement, during apical tooth, positively engaging is worked, to ensure 100% engagement success rate.Be " 201120087628 " see the patent No., the Chinese utility model patent that name is called " namely one stops the flexible engagement starter that namely electrifies ".But in real work, in the process that flexible engagement is carried out, positively engaging spring also can be compressed, and causes pressure increase between gear and gear ring, and frictional force increases, gear ring serious wear.Meanwhile, flexible engagement moment possibly cannot overcome this frictional force, only has and works by positively engaging, and namely flexible to engage the probability worked very little, there will be the fault similar with pure positively engaging starter motor.

In the present embodiment, described startup module 100 comprises starter relay 3 and time delay relay 4, described starter relay 3 comprises the relay stationary contact 33a be oppositely arranged, 33b, relay movable contact 32, relay terminal 31 and relay coil 34, described time delay relay 4 comprises the time delay relay stationary contact 43a be oppositely arranged, 43b, time delay relay movable contact 42, time delay relay terminal 41, time delay relay coil 44 and time delay module 45, described relay terminal 31 is connected with described key door switch 2 and described time delay relay terminal 41 respectively, described time delay module 45 is connected with described time delay relay terminal 41 and described time delay relay coil 44 respectively, described relay stationary contact 33a, 33b is connected with described battery pack 1 and described pull in winding terminal 53 respectively, described time delay relay stationary contact 43a, 43b respectively with described relay stationary contact 33a, 33b and described hold-in winding terminal 51 connect.
Specifically, starter relay 3 comprises relay terminal 31, relay coil 34, relay movable contact 32 and two relay stationary contact 33a and 33b, wherein, relay terminal 31 is connected to battery pack 1 by key door switch 2, relay stationary contact 33a is directly connected to battery pack 1, and relay stationary contact 33b is connected to the pull in winding terminal 53 of magnetic switch 5.Time delay relay 4 comprises time delay relay terminal 41, time delay relay coil 44, time delay relay movable contact 42 and two time delay relay stationary contact 43a and 43b, wherein, time delay relay terminal 41 is connected with the relay terminal 31 of starter relay 3, time delay relay stationary contact 43a is connected with the relay stationary contact 33b of starter relay 3, and time delay relay stationary contact 43b is connected to the hold-in winding terminal 51 of magnetic switch 5.In addition, time delay relay 4 also has time delay module 45, is connected between time delay relay terminal 41 and time delay relay coil 44.Wherein, the time delay module 45 of time delay relay can be delay circuit, also can be the time delay device in the electromagnetic type time relay, as short circuit cover.In addition, also delay power can be realized by the stroke strengthened between relay main contacts.
Magnetic switch 5 comprises pull in winding terminal 53, hold-in winding terminal 51, is connected to current-limiting resistance 52, pull in winding 58, hold-in winding 59, accumulator terminal 54, motor terminal 55, movable contact 57 and two stationary contact 56a and 56b between described pull in winding terminal 53 and described hold-in winding terminal 51.
Fig. 2 is the wiring diagram of first embodiment of the invention, there is shown described starter relay 3, described time delay relay 4, the position between described magnetic switch 5 and described motor 6 and wiring relation.
The working procedure that this has the starter motor of second order engagement capability is introduced referring to Fig. 1 and Fig. 2.After key door switch 2 is connected, electric current is by the terminal 31 engage relay coil 34 of starter relay 3, and starter relay moves plunger, and to be subject to effect top in figure of electromagnetic force mobile, and the movable contact 32 of starter relay 3 and two stationary contact 33a, 33b are connected.Like this, electric current just can flow into the pull in winding terminal 53 of magnetic switch 5 by the contact of starting starter relay 3, and flows into hold-in winding terminal 51 by current-limiting resistance 52, thus is energized to the pull in winding 58 of magnetic switch 5 and hold-in winding 59.Now electric current is also by the terminal 41 of relay 4, but due to the effect of time delay module 45, therefore the contact 42 of relay 4 and 43a, 43b can not demand workings.Under the effect of pull in winding 58 and hold-in winding 59 electromagnetic force, it is mobile that the dynamic plunger of magnetic switch 5 starts top in figure, and drive clutch driving gear (not shown) to get forward by shift fork (not shown).
When actuation gear and engine flywheel gear ring end face offset, flexible engagement is worked, starter motor starts slow-speed, due to current-limiting resistance 52 of having connected in hold-in winding 59, its electric current is less, make the electromagnetic force of generation be not enough to compression positively engaging spring, therefore positively engaging is inoperative by reasonably designing, meanwhile, the positive pressure acting on gear and gear ring end face can not also be strengthened.
The terminal 41 of time delay relay 4 is after energising certain hour t, the electromagnetic force that its coil 44 produces starts movable contact 42 and two stationary contact 43a and 43b are closed, electric current flows into the hold-in winding terminal 51 of magnetic switch 5 by contact 42 and 43, then current-limiting resistance 52 is shorted, in hold-in winding 59, electric current increases, and the electromagnetic force of magnetic switch increases.Because the electric current passed through in the main contact 42,43 of time delay relay 4 is only the electric current by magnetic switch 5 hold-in winding 59, its current value is less, therefore time delay relay 4 can be designed as small volume, with cost-saving.
Arranging of time t can obtain from the statistics being energized to the engaging-in gear ring of the apical tooth that the staggers time used according to flexible engagement starter, its settings will ensure that the contact of time delay relay 4 in normal flexible engagement process does not close, generally preferred between 50ms to 100ms.After time t, the make contact of time delay relay 4, now has two kinds of situations:
I flexibility engages the apical tooth that successfully staggers
Now actuation gear engaging-in engine flywheel gear ring, the dynamic plunger of magnetic switch 5 can continue mobile, the increase of magnetic switch 5 electromagnetic force can improve the engaging-in speed of actuation gear, make movable contact 57 and stationary contact 56a, actuation gear engaging-in sufficiently long distance when 56b connects, avoids occurring beating tooth fault.
II flexibility engages the apical tooth that cannot stagger
For general flexible engagement starter, namely there is apical tooth fault in this situation, actuation gear cannot engaging-in gear ring, starting failure.If also can solenoid winding be burnt after long-time energising.And for the present invention, because now magnetic switch 5 electromagnetic force increases, the numerical value of this electromagnetic force can be obtained by theory calculate, namely the pre-compression force of positively engaging spring is obtained by the pre compressed magnitude of positively engaging spring during apical tooth and the Rigidity Calculation of positively engaging spring, take shift fork as research object, shift fork lower end is center of rotation, now the electromagnetic force moment that this center of rotation produces relatively needs the moment being greater than relative this center of rotation generation of positively engaging spring pre-compression force, namely now dynamic plunger can continue mobile, until movable contact 57 and stationary contact 56a, 56b connects, big current passes through motor, drive actuation gear rotates, stagger apical tooth, and under the effect of positively engaging spring release force rapid engaging-in gear ring, realize positively engaging.
After starter motor completes starting, key door switch 2 disconnects, the coil 34 of starter relay 3 and all power-off of the coil 44 of time delay relay 4, the dynamic plunger of starter relay 3 and time delay relay 4 moves to Figure below under the effect of return spring, make movable contact 32(42) with stationary contact 33a(43a) and 33b(43b) to disconnect, like this, the pull in winding terminal 53 of magnetic switch 5 and hold-in winding terminal 51 all power-off, when movable contact 57 does not disconnect, electric current is by accumulator terminal 54, motor terminal 55, pull in winding 53, current-limiting resistance 52 and hold-in winding 51 ground connection.Now pull in winding 53 and hold-in winding 51 are connected, and electric current is identical but around on the contrary, the electromagnetic force that their produce just is offset.Under the effect of return spring, movable contact 57 departs from stationary contact 56a and 56b, thus makes actuating motor 6 loop power-off, and starter motor stops the rotation.Dynamic plunger drives shift fork to get back to initial position, and drives one-way element and actuation gear return, and actuation gear is deviate from from flywheel ring gear.Starter motor quits work, and gets back to reset condition.
The advantage of the present embodiment is: flexibility engagement can be separated from the time with positively engaging, when flexible engagement is unsuccessful, positively engaging is carried out again, ensures the engagement success rate of 100%, reduces the infringement to gear ring simultaneously.
Another advantage of the present embodiment is: the small volume of time delay relay 4, uses lower cost to get final product practical function.
The advantage that also has of the present embodiment is: if starter relay 3 cannot be connected due to fault, then all do not have electric current in the pull in winding 53 of magnetic switch 5 and hold-in winding 51, can protect two coils.
Second embodiment
Be the circuit diagram of the second embodiment of the present invention see Fig. 3, Fig. 3.Described startup module 100 comprises starter relay 3 and time delay relay 4, described starter relay 3 comprises the relay stationary contact 33a be oppositely arranged, 33b, relay movable contact 32, relay terminal 31 and relay coil 34, described time delay relay 4 comprises the time delay relay stationary contact 43a be oppositely arranged, 43b, time delay relay movable contact 42, time delay relay terminal 41, time delay relay coil 44 and time delay module 45, described relay terminal 31 is connected with described key door switch 2 and described time delay relay terminal 41 respectively, described time delay module 45 is connected with described time delay relay terminal 41 and described time delay relay coil 44 respectively, described relay stationary contact 33a, 33b is connected with described battery pack 1 and described pull in winding terminal 53 respectively, described time delay relay 4 stationary contact 33a, 33b is connected with described battery pack 1 and described hold-in winding terminal 51 respectively.
In the present embodiment, the stationary contact 43a of time delay relay 4 is directly connected to battery pack 1, but not is connected to the stationary contact 33b of starter relay 3.
The working procedure of this embodiment starting arrangement in parallel is identical with the first embodiment, does not repeat them here.
The advantage of the second embodiment is: by the electric current of starter relay 3 contact when can reduce work.
3rd embodiment
Be the circuit diagram of the third embodiment of the present invention see Fig. 4, Fig. 4.Described startup module 100 comprises starter relay 3 and thermoswitch 8, described starter relay 3 comprises the relay stationary contact 33a be oppositely arranged, 33b, relay movable contact 32, relay terminal 31 and relay coil 34, described relay terminal 31 is connected with described key door switch 2, described relay stationary contact 33a, 33b is connected with described battery pack 1 and described pull in winding terminal 53 respectively, and two contacts of described thermoswitch 8 are connected with described pull in winding terminal 53 and described hold-in winding terminal 51 respectively.Namely the time delay relay 4 in first and second embodiment, all can use thermoswitch 8 to replace.Two contacts of thermoswitch 8 connect pull in winding terminal 53 and hold-in winding terminal 51 respectively, and thermoswitch 8 is by the temperature triggered of magnetic switch.
Below the working procedure of the present embodiment is explained.During original operating state, thermoswitch 8 contact disconnects, therefore electric current flows into the pull in winding terminal 53 of magnetic switch 5 by the contact of starting starter relay 3, and flow into hold-in winding terminal 51 by current-limiting resistance 52, thus be energized to the pull in winding 58 of magnetic switch 5 and hold-in winding 59.When rear generation apical tooth got by gear, due to current-limiting resistance 52 of having connected in hold-in winding 59, its electric current is less, and its electromagnetic force produced is not enough to compression positively engaging spring, therefore positively engaging is inoperative.
If flexible engagement cannot realize engagement, then the coil heating of magnetic switch 5 after apical tooth, thermoswitch 8 after reaching uniform temperature, is caused to close, by resistance 52 short circuit, in hold-in winding, electric current increases, and provides larger electromagnetic force, overcome positively engaging spring force, connect main contact, realize positively engaging.

Namely magnetic switch 5 comprises pull in winding 58, hold-in winding 59, is arranged at pull in winding terminal 53, accumulator terminal 54, motor terminal 55, movable contact 57, two stationary contact 56a and 56b at the common top of pull in winding 58 and hold-in winding 59.In addition, also comprise interpole coil 513 and be arranged at the annex coil terminals 511 at interpole coil 513 top.Annex coil terminals 511 is connected with the stationary contact 43b of time delay relay 4.
Introduce the working procedure of the starter motor of this embodiment below.After key door switch 2 is connected, electric current is by the terminal 31 engage relay coil 34 of starter relay 3, and starter relay moves plunger, and to be subject to effect top in figure of electromagnetic force mobile, and the movable contact 32 of starter relay 3 and two stationary contact 33a, 33b are connected.Like this, electric current just can flow into the pull in winding terminal 53 of magnetic switch 5 by the contact of starting starter relay 3, thus is energized to the pull in winding 58 of magnetic switch 5 and hold-in winding 59.Now electric current is also by the terminal 41 of relay 4, but due to the effect of time delay module 45, therefore the time delay relay movable contact 42 of relay 4 and time delay relay stationary contact 43a, 43b can not demand working.Under the effect of pull in winding 58 and hold-in winding 59 electromagnetic force, it is mobile that the dynamic plunger of magnetic switch 5 starts top in figure, and drive clutch driving gear (not shown) to get forward by shift fork (not shown).
When actuation gear and engine flywheel gear ring end face offset, flexible engagement is worked, starter motor starts slow-speed, the resistance value of hold-in winding 59 is designed under 24V voltage, its electromagnetic force produced is not enough to compression positively engaging spring, therefore positively engaging is inoperative, meanwhile, the positive pressure acting on gear and gear ring end face can not also be strengthened.
The terminal 41 of time delay relay 4 is after energising certain hour t, the electromagnetic force that its coil 44 produces starts time delay relay movable contact 42 and two time delay relay stationary contact 43a and 43b are closed, electric current passes through interpole coil terminal 511 and the interpole coil 513 of contact time delay relay movable contact 42 and two time delay relay stationary contact 43a and 43b inflow magnetic switch 5, and the electromagnetic force produced in interpole coil 513 makes the electromagnetic force of magnetic switch 5 increase.Because the electric current passed through in the time delay relay movable contact 42 of time delay relay 4 and two time delay relay stationary contact 43a and 43b is only the electric current by magnetic switch 5 interpole coil 513, its current value is less, therefore time delay relay 4 can small volume, with cost-saving.
Arranging of time t can obtain from the statistics being energized to the engaging-in gear ring of the apical tooth that the staggers time used according to flexible engagement starter, and its settings will ensure that the contact of time delay relay 4 in normal flexible engagement process does not close.After time t, the make contact of time delay relay 4, now has two kinds of situations:
I flexibility engages the apical tooth that successfully staggers
Now actuation gear engaging-in engine flywheel gear ring, the dynamic plunger of magnetic switch 5 can continue mobile, the increase of magnetic switch 5 electromagnetic force can improve the engaging-in speed of actuation gear, make movable contact 57 and stationary contact 56a, actuation gear engaging-in sufficiently long distance when 56b connects, avoids occurring beating tooth fault.
II flexibility engages the apical tooth that cannot stagger
For general flexible engagement starter, namely there is apical tooth fault in this situation, actuation gear cannot engaging-in gear ring, starting failure.If also can solenoid winding be burnt after long-time energising.And for having the starter motor of second order engagement capability, because now magnetic switch electromagnetic force increases, its electromagnetic force is designed to overcome positively engaging spring force, dynamic plunger can be continued mobile, until movable contact 57 and stationary contact 56a, 56b connects, big current is by motor, and drive actuation gear to rotate, stagger apical tooth, and under the effect of positively engaging spring release force rapid engaging-in gear ring, realize positively engaging.
After starter motor completes starting, key door switch 2 disconnects, the coil 34 of starter relay 3 and all power-off of the coil 44 of time delay relay 4, the dynamic plunger of starter relay 3 and time delay relay 4 moves to Figure below under the effect of return spring, make movable contact 32(42) with stationary contact 33a(43a) and 33b(43b) to disconnect, like this, the pull in winding terminal 53 of magnetic switch 5 and interpole coil terminal 511 all power-off, when movable contact 57 does not disconnect, electric current is by accumulator terminal 54, motor terminal 55, pull in winding 53 and hold-in winding 51 ground connection.Now pull in winding 53 and hold-in winding 51 are connected, and electric current is identical but around on the contrary, the electromagnetic force that their produce just is offset.Under the effect of return spring, movable contact 57 departs from stationary contact 56a and 56b, thus makes electric motor loop power-off, and starter motor stops the rotation.Dynamic plunger drives shift fork to get back to initial position, and drives one-way element and actuation gear return, and actuation gear is deviate from from flywheel ring gear.Starter motor quits work, and gets back to reset condition.
The advantage of the 5th embodiment is: without current-limiting resistance in magnetic switch, is easy to arrange.
