Abstract
A novel automobile starting motor comprises a permanent magnet direct current motor and electromagnetic switches, wherein each of the electromagnetic switches is composed of an movable iron core, and a suction coil and a holding coil which are wound on the movable iron core, the permanent magnet direct current motor consists of an armature and a brush, and a driving shaft is further provided, and is provided with a driving pinion thereon, the driving shaft is connected with the output shaft of the permanent magnet direct current motor, the suction coil is connected in series with a winding element of the armature through the brush, and the winding element of the armature is connected with a cathode of an automobile accumulator through a bonding negative brush. As the novel automobile starting motor effectively avoids the gear pressing state in the forced meshing of the starting motor, the structure and manufacture technology of all the electromagnetic switches are simpler than the production of a common starting motor electromagnetic switch. The power of the suction coil is correspondingly reduced, and copper wires are saved. As the driving pinion slowly rotates during the meshing, the meshing of the driving pinion is soft, and reduces impact, thereby improving the service lives of the driving pinion and an engine flywheel fluted disc.
Description
(1) technical field
The utility model relates to a kind of automobile start motor.
(2) background technique
The automobile start motor of existing various ways belongs to positively engaging formula starter motor mostly.This starter motor in the course of the work, its driving pinion is when meshing with the engine flywheel fluted disc, if fail directly to slip in the teeth groove of engine flywheel fluted disc, then can occur on the gear teeth end face that the driving pinion increment withstands on the engine flywheel fluted disc apical tooth phenomenon taking place promptly.At this moment, have to rely on the engage spring on the compression overrunning clutch, make the moving iron core of magnetic switch continue to move, connect up to main contact, when making starter motor energising rotation, driving pinion just can slip in the engine flywheel fluted disc teeth groove under the pressure effect of engage spring.Because the actuating motor rotating speed is higher, engagement is suppressed when excessive, and the power requirements of magnetic switch pull-in winding is higher, and volume increases.Pressure hour, driving pinion is difficult for entering engine flywheel fluted disc teeth groove, and causes the mill teeth problem, damages Flywheel fluted disc and starter motor driving pinion.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing automobile start motor, the utility model provide a kind of can significantly avoid the starter motor driving pinion and start the Flywheel fluted disc engagement time by the new automobile starter motor of the problem of mill teeth.
The technical scheme in the invention for solving the technical problem is: a kind of new automobile starter motor, comprise permanent magnet DC motor and magnetic switch, and described magnetic switch comprises moving iron core and pull-in winding, hold-in winding on the described moving iron core; Described permanent magnet DC motor comprises armature and brush; Also comprise transmission shaft, described transmission shaft is provided with driving pinion, described transmission shaft is connected with the output shaft of described permanent magnet DC motor, described pull-in winding is connected with the element of winding of described armature by described brush, and the element of winding of described armature links to each other with the negative pole of car accumulator by bonding negative pole brush.
When automobile starting key switch is closed, the pull-in winding of magnetic switch and hold-in winding energising, wherein the electric current of pull-in winding will flow through the element of winding branch road of armature by brush, after flow to battery terminal negative through bonding negative pole brush, form current loop.Like this, when producing the moving iron core of electromagnetism suction pulling force pulling, pull-in winding, hold-in winding energising move to static iron core, when thereby the pulling shift fork is pushed driving pinion to the engine flywheel fluted disc, the armature that is in series with pull-in winding also passes through certain electric current, under the magnetic force effect that permanent magnetism magnetic pole forms, slowly rotate, logical moving planetary gear reducing mechanism drives transmission shaft and rotates, thereby realizes that driving pinion slowly rotates, driving pinion then smoothly slippage set out in the engine flywheel fluted disc teeth groove.When movable contact and stationary contact were connected when engagement is finished, pull-in winding was by short circuit, and armature obtains full voltage, and starter motor drives the rotation of engine flywheel fluted disc with peak output.
The beneficial effects of the utility model are: apical tooth state when having avoided the starter motor positively engaging effectively, all magnetic switch structures, the manufacturing of the common relatively starter motor magnetic switch of manufacturing process want simple.Copper cash is saved in the corresponding reduction of pull-in winding power.Because driving pinion slowly rotates during engagement, make the driving pinion engagement soft, reduce to impact, thus the life-span of improving driving pinion and engine flywheel fluted disc.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of new automobile starter motor comprises permanent magnet DC motor and magnetic switch, and described magnetic switch comprises moving iron core 1 and pull-in winding 2, hold-in winding 3 on the described moving iron core 1; Described permanent magnet DC motor comprises armature 4 and brush 5; Also comprise transmission shaft 6, described transmission shaft 6 is provided with driving pinion 7, and described transmission shaft 6 is connected with the output shaft of described permanent magnet DC motor.Described pull-in winding 2 is connected with the element of winding of described armature 4 by described brush 5, and the element of winding of described armature 4 links to each other with the negative pole of car accumulator by bonding negative pole brush.
When automobile starting key switch 8 closures, the pull-in winding 2 of magnetic switch and hold-in winding 3 energisings, wherein the electric current of pull-in winding 2 will flow through the element of winding branch road of armature 4 by brush 5, after flow to battery terminal negative through bonding negative pole brush, form current loop.Like this, inhale the moving iron core of pulling force pulling 1 and move when 3 energisings of pull-in winding 2, hold-in winding produce electromagnetism to static iron core, when thereby pulling shift fork 9 is pushed driving pinion 7 to engine flywheel fluted disc 10, the armature 4 that is in series with pull-in winding 2 also passes through certain electric current, under the magnetic force effect that permanent magnetism magnetic pole forms, slowly rotate, logical moving planetary gear reducing mechanism drives transmission shaft 6 and rotates, thereby realize that driving pinion 7 slowly rotates, 7 of driving pinions slippage are smoothly seted out in the teeth groove of engine flywheel fluted disc 10.When movable contact and stationary contact were connected when engagement is finished, pull-in winding 2 was by short circuit, and armature 4 obtains full voltage, and starter motor drives 10 rotations of engine flywheel fluted disc with peak output.
