The first embodiment
The first embodiment's of the present utility model circuit diagram has been shown among Fig. 2.Starting arrangement in parallel among the figure has the battery pack 1 that is connected in parallel again after storage battery is connected in twos, the starter motor 4 of 2, two parallel connections of key door switch and 5 and starter relaies 3.Starter motor 4 comprises having pull in winding 47, hold-in winding 48, accumulator terminal 41, switch terminal 42, motor terminal 43, motor terminal 44, movable contact 46 and two stationary contact 45a, the magnetic switch 40 of 45b, motor 49 and OCP411.Starter motor 5 comprises having pull in winding 57, hold-in winding 58, accumulator terminal 51, switch terminal 52, motor terminal 53, motor terminal 54, movable contact 56 and two stationary contact 55a, the magnetic switch 50 of 55b, motor 59 and OCP511.Starter relay 3 comprises relay terminal 31, negative terminal 35, coil 34, movable contact 32 and two stationary contact 33a and 33b.
Wherein, the main contact of the main contact of magnetic switch 40 and magnetic switch 50 is for being connected in series, and motor 49 and motor 59 are for being connected in parallel, and starter relay negative terminal 31 is connected in series rear ground connection with OCP 411 and OCP 511.OCP411 and OCP511 are arranged at respectively on magnetic switch 40 and the magnetic switch 50.
Introduce the working procedure of this parallel connection starting arrangement below with reference to Fig. 2.After key door switch 2 is connected, because OCP 411 and OCP 511 all are in on-state, electric current relay terminal 31 by starter relay 3 from battery pack 1 is connected starter relay coil 34, the effect that the moving plunger of starter relay is subject to electromagnetic force top in the figure is mobile, so that the movable contact 32 of starter relay and two stationary contact 33a, 33b connects.Like this, electric current just can flow into respectively by the contact of starter relay 3 switch terminal 52 of magnetic switch 50 in the switch terminal 42 of magnetic switch 40 in the starter motor 4 and the starter motor 5, thereby gives respectively the pull in winding 47 of magnetic switch 40 and pull in winding 57 and hold-in winding 58 energisings of hold-in winding 48 and magnetic switch 50.At this moment, owing to two pull in windings 47 and 57 are connected with motor 49 and 59 respectively, little electric current is arranged respectively by two motors, so that motor 49 and motor 59 beginning slow-speeds.Simultaneously, under the effect of coil electromagnetic force, the moving plunger of magnetic switch 40 and magnetic switch 50 respectively in the figure top mobile, and drive the clutch driving gear (not shown) by the shift fork (not shown) and get forward.When actuation gear and engine flywheel gear ring end face offseted, because the starter motor slow-speed, the apical tooth that can stagger made the engaging-in engine flywheel gear ring of actuation gear.Like this, it is mobile that the moving plunger of two magnetic switch can continue, and the final so that movable contact 46 of magnetic switch 40 connects with two stationary contact 45a and 45b, also so that the movable contact 56 of magnetic switch 50 and two stationary contact 55a and 55b connection.Because the main contact of magnetic switch 40 and magnetic switch 50 is for being connected in series, so in the situation about only all connecting in the sound contact of magnetic switch 40 and magnetic switch 50, large electric current just can be by two magnetic switch main contact and be switched to the motor 49 of starter motor 4 and the motor 59 of starter motor 5 in, so that all full moment of torsion output of starter motor 4 and starter motor 5 realizes piloting engine.
When starter motor apical tooth in the starting arrangement in parallel can't engaging-in gear ring, if current"on"time is long, then solenoid winding heating, when rising to setting threshold, temperature will trigger the OCP of this starter motor, make its disconnection, then starter relay 3 coils 34 are opened circuit, and relay 3 contacts disconnect, and two starter motors quit work.Like this, can prevent that overheating of starter from damaging and protecting another starter motor in parallel.
After starter motor is finished starting, key door switch 2 disconnects, coil 34 outages of relay 3, the moving plunger of relay 3 is mobile below in the figure under the effect of return spring, so that movable contact 32 disconnects with stationary contact 33a and 33b, like this, the switch terminal 42 of magnetic switch 40 and 52 outages of the switch terminal of magnetic switch 50, current uniform is two branch roads in two starter motors, and one is passed through motor 49,59 loops, and starter motor continues rotation; Another is by pull in winding 47,57, hold-in winding 48,58 ground connection.This moment pull in winding 47,57 and hold-in winding 48,58 series connection, electric current is identical but around on the contrary, the electromagnetic force that their produce is just offset. Movable contact 46,56 breaks away from stationary contact 45a, 55a and 45b, 55b under the effect of return spring, thereby makes the electric motor loop outage, and starter motor stops the rotation.Two moving plungers drive respectively shift fork and get back to initial position, and drive 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 present embodiment advantage be: can avoid having in the starting arrangement in parallel starter motor to mesh when unsuccessful starter motor broken teeth or mill teeth fault.Simultaneously, be provided with OCP in the starting arrangement in parallel, prevent that one or more starter motor from meshing the switch coil burnout that the long-term energising of magnetic switch causes when unsuccessful.
Another advantage of the present embodiment is: two or starter relay control of many starter motors uses, can save cost.
The second embodiment
Shown in Fig. 3 is the second embodiment of the present utility model.
In the present embodiment, each starter motor in the starting arrangement in parallel all is furnished with starter relay, starter relay 3 control starter motors 4, starter relay 6 control starter motors 5, the relay terminal 31 and 61 of starter relay is connected in parallel, and stationary contact 33a and the 63a of cranking-motor relay also are connected in parallel.
In the present embodiment, because each cranking-motor relay is for being connected in parallel, all can disconnect all starter relaies when guaranteeing any one OCP work, OCP need to be arranged on the main line of each starter relay in parallel, therefore need to negative terminal 35,65 be set at each starter relay, each starter relay negative terminal 35, the 65 rear rear ground connection of connecting with the OCP of each starter motor parallel with one another.
In the starting process, each starter relay is controlled respectively the magnetic switch of corresponding starter motor.When a starter motor apical tooth being arranged can't engaging-in gear ring the time in the starting arrangement in parallel, after current"on"time was long, its starter motor OCP can disconnect, and can cut off simultaneously the electric current of all starter relay coils, so that all starter motors all quit work.Like this, can prevent that the overheating of starter of engaging-in gear ring does not burn, also can effectively protect other starter motors in the starting arrangement in parallel.
In addition, the working procedure of the present embodiment starting system in parallel is identical with the first embodiment.
The second embodiment's advantage is: use independent starter relay to control respectively each starter motor in parallel, be conducive to improve the reliability of whole starting system in parallel.
