Embodiment
Below in conjunction with accompanying drawing this improved positively engaging formula starter motor is described in further detail:
This improved positively engaging formula starter motor is made of starter motor body 1, time delay device 2, and starter motor body 1 comprises magnetic switch 5, starter armature M, shift fork 10, engage spring 11, driving mechanism 12; Time delay device 2 comprises delay circuit 3, executive component 4, resistance R, and the output terminal of delay circuit 3 is connected with executive component 4, and executive component 4 is connected in parallel by lead and resistance R; Magnetic switch 5 comprises sucking coil 6, hold-in winding 7, moving iron core 8; The stationary contact a of magnetic switch 5 and power supply E positive pole, ignition switch 9 are connected in parallel, and the stationary contact b of magnetic switch 5 is connected with the positive terminal of starter armature M; The A point of magnetic switch 5 is that the tapping point that is connected in parallel of sucking coil 6 and hold-in winding 7 is connected with power supply E is anodal by ignition switch 9; The input end of time delay device 2 is connected with the A point of magnetic switch 5 by lead, one end of the resistance R of time delay device 2 is connected with the B point of sucking coil 6, and the D point that is connected in parallel of the positive terminal of the other end of resistance R and starter armature M and the stationary contact b of magnetic switch 5 is connected; The negative pole of the B point of hold-in winding 7, power supply E negative pole, starter armature M all is connected with ground by lead.The moving iron core 8 of magnetic switch 5 connects engage spring 11 by shift fork 10, engage spring 11 and driving mechanism 12 attachings, the actuation gear of driving mechanism 12 and engine flywheel 13 engagements (referring to accompanying drawing 1).
Described time delay device 2 is connected in series in by lead between the A point of ignition switch 9 and magnetic switch 5 (referring to accompanying drawing 2).
Described executive component 4 is field effect transistor or relay.
We know by prior art, when the moment of giving magnetic switch 5 energisings, the 24V voltage of battery feed E all is added on sucking coil 6 and the hold-in winding 7, the electric energy of its acquisition is converted into mechanical kinetic energy, make and move iron core 8 accelerated motions and compressive engagement spring 11, this moment is when running into tooth to teeth groove, actuation gear can insert the teeth groove of engine flywheel 13 smoothly, simultaneously behind the movable touching plate short circuit of the stationary contact a of magnetic switch 5 and the moving iron core 8 that stationary contact b is moved to left, the voltage of power supply E all is applied on the starter armature M, starter armature M full-voltage starting, gear engagement and the full power rotation (referring to accompanying drawing 3) of actuation gear and engine flywheel 13.
But when running into the tooth top tooth, because the leverage of the moving iron core 8 in the magnetic switch 5 by shift fork 10 promotes driving mechanism 12 when moving to right, also promote the movable touching plate of moving iron core 8 simultaneously to moving to left, namely move to stationary contact a and stationary contact b direction, though this moment, actuation gear no longer moved ahead because of apical tooth, because there being flexible engage spring 11, shift fork 10 can continue to rotate around fulcrum, on one side the compressive engagement spring 11, on one side continue to promote movable touching plate move to left up to stationary contact a and stationary contact b closure.And meanwhile the tooth top of actuation gear the tooth of engine flywheel 13, it goes into rack member is that certain apical tooth pressure must be arranged, but the kinetic energy that stores because of engage spring 11 since the time too weak point can not be discharged fully, actual measurement as can be known should general not enough 10mS of time, show that this pressure is generally on the low side, the static elastic force when being far smaller than design; And this moment, stationary contact a and stationary contact b were closed, the output of starter armature M full power, and actuation gear will slip over the teeth groove of engine flywheel 13 easily in zero process of accelerating to rise, produce the mill teeth fault, thereby cause engagement failure (referring to accompanying drawing 3).
The inventor has carried out a large amount of contrasts and research to the related data of domestic and international solution mill teeth fault, and the special topic of having participated in domestic associated row expert is discussed, by deep repeatedly theoretical research and experimental demonstration repeatedly, the basic solution by time delay device 2 radical cure mill teeth chronic diseases has been proposed.The improved positively engaging formula starter motor of inventor's development, be to increase a time delay device 2 at traditional positively engaging starter motor, this time delay device 2 comprises delay circuit 3, executive component 4 and resistance R, can under any working state, thoroughly solve the engagement problem of actuation gear and engine flywheel 13, avoid the mill teeth fault of traditional positively engaging starter motor fully.The present invention especially is fit to be installed in the 24V diesel engine starting system and uses.
Research and development thought of the present invention is: series resistor R is in order to reduce the coil current of magnetic switch 5 in the current supply circuit of magnetic switch 5 coils, behind delay circuit 3 delays 100~150mS, with the resistance R short circuit, recover the normal current of magnetic switch 5 coils by executive component 4 field effect transistors or relay; Purpose is exactly to reduce the travelling speed of driving mechanism 12, reduce the decrement of engage spring 11, postpone the closing time of stationary contact a and the stationary contact b of magnetic switch 5 simultaneously, like this, the kinetic energy that is stored in 11 li of engage springs is able to abundant release, increase apical tooth power greatly, make in the teeth groove of the smooth engaging-in engine flywheel 13 of actuation gear.
This improved positively engaging formula starter motor is installed in time delay device 2 on the starter motor body 1 by two kinds of mounting types.
First kind of mounting type is: the input end of time delay device 2 is connected with the A point of magnetic switch 5 by lead, and the A point of magnetic switch 5 namely is the tapping point that is connected in parallel of sucking coil 6 and hold-in winding 7; The resistance R of the output terminal of time delay device 2 is connected in series between the tie point D point of stationary contact b of the positive terminal of the B point of sucking coil 6 and starter armature M and magnetic switch 5; The resistance of resistance R is 0.2~0.5 Ω, and the dc resistance of sucking coil 6 is 0.2~0.5 Ω, and the dc resistance of hold-in winding 7 is 1.5~2 Ω.Adopt this mounting type, time delay device 2 uses element few, and circuit is succinct, and is easy to make, and cost is low.No matter the executive component 4 of time delay device 2 is to adopt field effect transistor or relay, and time delay device 2 all can be normally, stable operation.Starter motor manufacturing enterprise need reequip the wiring (referring to accompanying drawing 1) of magnetic switch 5 when but installing.
Second kind of mounting type is: the resistance R of time delay device 2 is connected in series between the A point of ignition switch 9 and magnetic switch 5, and this moment is by resistance R sucking coil 6 and hold-in winding 7 these two groups of coils while current limlitings to magnetic switch 5.Adopt this mounting type very simple, starter motor manufacturing enterprise need not existing starter motor is done any change, only time delay device 2 need be directly installed on the existing starter motor shell to get final product.But, when the executive component 4 of time delay device 2 is when selecting field effect transistor for use, the polarity that need pay the utmost attention to field effect transistor is the P type, and the circuit of time delay device 2 is complicated, fabricating cost higher (referring to accompanying drawing 2).
It is not need to consider that it inserts polarity that executive component 4 adopts the benefit of relays, shortcoming be the contact of relay easily by scaling loss, influence the short circuit of 3 couples of current-limiting resistance R of delay circuit.
Executive component 4 adopts field effect transistors, because field effect transistor is non-contact work, has guaranteed working stability and the reliability of time delay device 2 self, but compared relay that field effect transistor is somewhat expensive.
Delay circuit 3 can be to adopt relay or field effect transistor designs voluntarily according to executive component 4.In addition, the delay circuit 3 of time delay device 2 also can adopt pulsewidth modulation (PWM) circuit control field effect transistor discontinuous operation between time delay, can save current-limiting resistance R, but the design meeting more complicated of corresponding delay circuit 3.
The working principle of this improved positively engaging formula starter motor specifically describes as follows:
When adopting first kind of mounting type: the current supply circuit of the sucking coil 6 of magnetic switch 5 is: the movable touching plate-stationary contact b of the D point that is connected in parallel of the positive terminal of the B point-starter armature M of the A point sucking coil 6 of power supply E-ignition switch 9-magnetic switch 5 and the tapping point-sucking coil 6 that is connected in parallel of hold-in winding 7 and stationary contact b-moving iron core 8.The current supply circuit of the hold-in winding 7 of magnetic switch 5 is: the C point of the A point-hold-in winding 7 of power supply E-ignition switch 9-magnetic switch 5-connection ground.
In the current supply circuit of sucking coil 6, the resistance R of time delay device 2 is connected in series between the tie point D point of the positive terminal of the A point of magnetic switch 5 and starter armature M and stationary contact b, the resistance of resistance R is 0.2~0.8 Ω, the dc resistance of sucking coil 6 is 0.2~0.8 Ω, resistance R has been connected in series metering function with sucking coil 6, to reduce the electric current of sucking coil 6, (according to practical experience, effect was better when this electric current reduction was made an appointment with half); Purpose is to reduce the acceleration of moving iron core 8 significantly, reduce the decrement of engage spring 11, the travelling speed of driving mechanism 12 is reduced greatly, when tooth top tooth position, the moving iron core 8 of magnetic switch 5 does not temporarily come to a halt because there being enough power, can't promote movable touching plate contact stationary contact a and stationary contact b, this moment, the actuation gear tooth that withstands engine flywheel 13 of driving mechanism 12 was waited for into tooth, under the effect of the delay circuit 3 of time delay device 2, after 100~150mS delay, the elastic force that is installed in the engage spring 11 of driving mechanism 12 back is fully discharged, and the elastic force of engage spring 11 makes driving mechanism 12 produce enough big apical tooth precompression roof pressure at the increment face of engine flywheel 13.Meanwhile, executive component 4 field effect transistors or the relay work of time delay device 2, with the resistance R short circuit, the electric current that flows through sucking coil 6 recovers normal, this moment, the 24V voltage of battery feed E all put on the sucking coil 6, make moving iron core 8 obtain enough power and remove halted state, promote movable touching plate move ahead until with stationary contact a and stationary contact b closure, make starter armature M obtain 24V voltage and begin full power operation, make the rotating speed of actuation gear by zero moment rising rapidly by driving mechanism 12, under enough big apical tooth precompression effect, rotate and slip in the teeth groove of engine flywheel 13.Adopt this installation method, executive component 4 can adopt both economical N-type field effect transistor (referring to accompanying drawing 1).
When adopting second kind of mounting type: because the resistance R of time delay device 2 is to be connected in series between the A point of ignition switch 9 and magnetic switch 5, the A point of magnetic switch 5 namely is that the tap of sucking coil 6 and hold-in winding 7 is connected in parallel a little, so this moment is by resistance R sucking coil 6 and hold-in winding 7 these two groups of coils while current limlitings to magnetic switch 5, the resistance of resistance R is that the dc resistance of 0.2 ~ 0.8 Ω, sucking coil 6 is 0.2 ~ 0.8 Ω, and the D.C. resistance of hold-in winding 7 is about 1.5 ~ 2 Ω; Its follow-up working procedure, purpose, final effect and first kind of mounting type of employing are just the same, so repeat no more.Must emphasize a bit: adopt second kind of mounting type, when the executive component 4 of time delay device 2 adopts field effect transistor, must consider the polarity of field effect transistor, should preferentially select P type field effect transistor for use.If select N-type field effect transistor, then the design meeting more complicated (referring to accompanying drawing 2) of delay circuit 3 for use.
This improved positively engaging formula starter motor increases time delay device 2 at traditional positively engaging starter motor, by aforementioned two kinds of mounting types, particularly is installed on the starter motor body 1 by first kind of mounting type, thoroughly solves the mill teeth problem, guarantees positive engagement.Used element is few, and is simple in structure, and fabricating cost is low, and it is reasonable, convenient to install, and effect is remarkable.By failure analysis and test, time delay device 2 working stabilities are reliable, and integral replacing is quick and easy, do not increase additional faults.
The above is the embodiment of this invention, above-mentioned not illustrating is construed as limiting flesh and blood of the present invention, the person of an ordinary skill in the technical field can make an amendment or is out of shape after having read this specification above-mentioned embodiment, and does not deviate from the spirit and scope of the invention.
