Its operation logic and beneficial effect is described in detail in conjunction with the circuit theory diagrams (as Fig. 1-2) of prior art and circuit theory diagrams of the present invention (Fig. 3).
As the automobile-used starting drive that Fig. 1 is one group of routine.During vehicle launch, ignition switch (key) is powered, electronic relay adhesive, and electromagnetic switch is started working thereupon, and usual electromagnetic switch has two effects, and one is play on-off action in start-up course, powers or power-off to starter; Two is pull shift fork that driven wheel is stretched out by dynamic iron core, drives engine with this.During startup, the pull-in winding of electromagnetic switch and hold-in winding produce equidirectional magnetic flux, and magnetic flux produces very strong attraction and attracts iron core motion, until the dynamic and static closing of contact after strengthening.Now pull-in winding is by main contacts short circuit, thus no longer includes electric current in coil and pass through, and only maintains the attracting state of dynamic iron core by the electric current in hold-in winding.Start after terminating, electronic relay disconnects, and before return spring does not also push dynamic and static contact open, electromagnetic switch starter terminal is in high potential, and the head end of hold-in winding is connected with the head end of pull-in winding, other end bonding ground connection.Such two groups of coils are just together in series again and again form current circuit, namely regenerate magnetic flux.Because now pull-in winding is with the sense of current is contrary before, and the hold-in winding sense of current is constant, so the flow direction that two groups of coils produce is contrary.In order to make electromagnetic switch disconnect smoothly, we allow two groups of coil turns consistent usually, so that disconnect moment in ignition switch, they produce counter magnetic flux of the same size and can cancel out each other.But in facts have proved, there is shortcomings in the starting drive of this routine:
1, consumptive material is many, and cost is high.In order to electromagnetic switch disconnects smoothly, the pull-in winding number of turn must be consistent with the hold-in winding number of turn, and hold-in winding generally for the current density reaching regulation, and often the number of turn is more.
2, useful life is short.In the process of production electromagnetic switch, two groups of coils are difficult to ensure that the numbers of turn are definitely consistent, and add the inconsistent etc. of its pile warp, electromagnetic switch often all can have the appearance of remanent magnetism when disconnecting, qualified switch is that remanent magnetism is very weak.No matter remanent magnetism is strong and weak, how much all can produce certain negative effect to the electric current arcing of dynamic and static contact when disconnecting.When arcing is serious to a certain extent, when dynamic and static contact sticks together, be originally that the electromagnetic switch of short-term operation will be energized for a long time, this is just easy to cause electromagnetic switch to be burnt, and even damages starter.
3, functions expanding is poor.In order to the flywheel ring gear of the driven wheel with engine that make starter better engages, the electromagnetic switch of part model can be rotated starter for driven wheel by storage battery electricity by pull-in winding and be provided certain rotating speed before shift fork reaches position.Reach the operation voltage requirement of starter, the resistance of pull-in winding just needs as far as possible little, again because the restriction of its number of turn, so the pull-in winding of the slow engagement electromagnetic switch of routine all can select thicker line style.This is at cost and spatially all can have larger consumption, and due to this limitation, the electromagnetic switch of a lot of model is not easy to realize slow engagement.
As shown in Figure 2, be double contact structure with Fig. 1 unlike the electromagnetic switch in this automobile-used starting drive, operation principle and Fig. 1 of this kind of structure are basically identical, although difference is that in Fig. 1, after the dynamic and static closing of contact, pull-in winding is by short circuit, itself and electromagnetic switch starter terminal are in on-state always.And this double contact structure in Fig. 2, its pull-in winding is then about in 2mm stroke at dynamic and static contact touching late contact and disconnects with electromagnetic switch starter terminal.Utilize this open circuit structure, the pull-in winding number of turn in this double contact switch that market occurs considerably reduces many, reduces costs with this.Although cost obtains certain control, can the shortcoming that such starting drive has had again a few place new:
1, parts require higher.Originally only need the mechanical structure of management and control list group contact break-make will carry out now the two group of management and control, this just need require higher in the precision of its parts.
2, larger remanent magnetism occurs.But this is a potential fatal defect, originally seeming the pull-in winding being in off state can reclose with electromagnetic switch starter terminal in electromagnetic switch reseting procedure, and now dynamic and static contact does not also disconnect completely.Storage battery electricity can form a loop instantaneously through two groups of coils, and those double contact switchs decreasing the pull-in winding number of turn during this time just there will be a larger remanent magnetism.Thus seriously blocked the speed that dynamic and static contact pushed open by return spring, even occur that remanent magnetism keeps phenomenon.Such electromagnetic switch life-span is not long, and more exacerbates the possibility that starter burns out.
Fig. 3 is circuit theory diagrams of the present invention, its distinguishing feature cast aside before the structure of two groups of coils end points altogether, and the electronic relay of correspondence also possesses two outputs and electronic relay hold-in winding terminal and electronic relay pull-in winding terminal simultaneously, it connects the head end of pull-in winding and the head end of hold-in winding respectively.When starting beginning, electronic relay hold-in winding terminal and electronic relay pull-in winding terminal connect two groups of coil power supplies that storage battery electricity is electromagnetic switch simultaneously, to ensure that two groups of coils produce equidirectional magnetic flux at one time.At the end of startup, starter relay storage battery electricity one end can before electromagnetic switch main contacts disconnects preferentially and electronic relay hold-in winding terminal and electronic relay pull-in winding terminal disconnect.That is, in electromagnetic switch reseting procedure, as long as electronic relay hold-in winding terminal place is " 0 " current potential, even if electromagnetic switch starter terminal is also in high potential also can not form current circuit, magnetic flux is not had without electric current, this just can fundamentally solve remanent magnetism problem, and pull-in winding also can break away from the limitation of the number of turn simultaneously, coordinates starter to realize better slow engagement.This can not only good production control cost, electromagnetic switch can also be made to alleviate than original arcing, reduce the possibility of dynamic and static contact adhesion, thus the useful life of starter and even whole starting drive is protected.
Embodiment above describes general principle of the present invention, principal character and advantage; the technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; under the scope not departing from the principle of the invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the scope of protection of the invention.
