Due to the adoption of the structure, the ignition system of automobile engine starter has the advantages that residual magnetic torque force, produced after the ignition switch is switched off, of an internal circuit of the starter is eliminated, and therefore the aims of shortening run-down time of the starter and reducing final sound and noise are achieved after an isolator is disengaged from a flywheel ring gear of an engine; final sound of the starter can be controlled through the double-throw structure of the electromagnetic switch, unnecessary mechanical abrasion to the starter is reduced after the ignition switch is switched off, and therefore the service life is prolonged.
Description
Technical field
The present invention relates to compression ignition engine starter motor technical field, particularly a kind of ignition system of automotive engine starter.
Background technique
The starter motor of compression ignition engine comprises direct current generator, operating mechanism (magnetic switch), reducing gear and transmission device (engaging mechanism).What wherein operating mechanism (magnetic switch) was brought into play in starter motor application act as the most important thing, it has guaranteed starter driving gear and engine flywheel smooth engage and power-off after return, and the timely break-make of magnetic switch main contact.Magnetic switch is a contactor, in practical operation, switch starting, magnetic switch energising, due to identical by the current direction of sucking coil and hold-in winding, the magnetic force direction therefore producing is identical, under the acting in conjunction of two coil magnetic force, making iron core (movable touching plate) overcome spring force moves, drive shift fork to push actuation gear to flywheel, meanwhile, moving iron core is the stationary contact to end by movable contact top.In the time that actuation gear engages with flywheel, the stationary contact of movable contact end is connected, and makes starter motor pass into starting current, produces normal electrical magnetic torque and pilots engine.When movable contact is connected the stationary contact of magnetic switch end, sucking coil is by short circuit, and movable core remains on the position of adhesive by the magnetic force of hold-in winding.After engine start, in the moment that disconnects switch starter, movable contact is still in contact stationary contact position, now, the opposite current of passing through in sucking coil and hold-in winding, sucking coil has produced and the rightabout magnetic flux of hold-in winding, and two coil magnetic force are cancelled each other, moving iron core resets under the effect of spring force, and actuation gear is exited; At the same time, also return of the servo-actuated iron core of movable contact, cuts off starter circuit capable, and starter motor just quits work.
But now the one-way element of starter motor departs from after engine flywheel gear ring, is not to stop operating immediately, but continue rotation under rotary inertia and remanent magnetism torque force, then stop slowly.According in SQR.04.216-2010 " starter motor assembly technical specifications " 4.11, starter motor rundown time is defined under no-load running and cuts off the electricity supply, and armature stops operating in 2s, and after endurance test, armature should stop transhipment in 3s.
At present, the rundown time of starter motor can meet the requirement of standard substantially, its rundown time of new starter motor greatly about 1.2s-1.8s not etc., but also have even can exceed this standard.This has just caused starter motor in stalling, to produce sharp-pointed electromagnetism and mechanicalness noise, has caused great inessential wearing and tearing, the working life of having reduced starter motor.The time of a starter motor ato unit is less than this value under normal circumstances.
Summary of the invention
Technical problem to be solved by this invention is, for the deficiencies in the prior art, a kind of ignition system of automotive engine starter is provided, to reach the remanent magnetism torque force of eliminating starter motor home loop after ignition switch power-off, after realizing one-way element disengaging engine flywheel gear ring, reducing of starter motor rundown time, reduces last or end syllable, noise, improves the object in the working life of starter motor.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of ignition system of automotive engine starter, comprise ignition switch, the magnetic switch being connected with ignition switch, described magnetic switch comprises obtaining electric end, pull-in winding, hold-in winding, movable touching plate, the motor being connected with pull-in winding, the first stationary contact, the second stationary contact, the first described stationary contact is connected with power supply, the second described stationary contact is connected with described pull-in winding, described movable touching plate is connected with return spring, described ignition system also comprises and is arranged on first on movable touching plate return-stroke electric discharge stationary contact, the second electric discharge stationary contact.
Described movable touching plate magnetic switch electricly hold to such an extent that connect the first stationary contact, the second stationary contact under electricity condition, return spring described under this state is extended state.
Under described return spring contraction state, described movable touching plate is connected the first electric discharge stationary contact, the second electric discharge stationary contact.
The first described electric discharge stationary contact ground connection, the second described electric discharge stationary contact is connected with described pull-in winding.
Described power acquisition storage battery, its positive pole is connected with the first stationary contact.
The present invention adopts said structure, has the following advantages: 1, the remanent magnetism torque force of starter motor home loop after the power-off of elimination ignition switch, and after realizing one-way element disengaging engine flywheel gear ring, reducing of starter motor rundown time, fundamentally reduces last or end syllable, noise; 2, the present invention can realize the control to starter motor last or end syllable by the double-throw structure of magnetic switch, and reduces after ignition switch disconnection, and the unnecessary mechanical wear of starter motor, to improve working life.
