Description
Technical field
The utility model relates to the starter motor field, relates to a kind of starter motor shift fork fulcrum structure in particular.
Background technique
Along with science and technology development, automobile has become the product of popularizing gradually, and as the motor of automobile core component, because it needs the support of external force when starting, old friends have invented starter motor, this starter motor is converted into mechanical energy with electricity of accumulator, thereby drives the engine flywheel rotation and the startup of realization motor.
Existing a kind of starter motor 100, as shown in Figure 1, it is to be provided with actuating motor 11 in protecgulum 10, and this also is provided with wiring terminal 12 above actuating motor 11, the electric contact piece of this wiring terminal 12 is arranged on the end of iron core 13, this iron core 13 is arranged in the switch sleeve 14 of protecgulum 10 above the actuating motor 11, these switch sleeve 14 outsides also are provided with coil unit 19, this coil unit 19 is via the magnetic switch (not shown) control that is arranged on starter motor 100 tops, the end of this iron core 13 also is provided with Returnning spring 15, the end in addition of this iron core 13 links to each other with an end of shift fork 16, the other end of shift fork 16 then leans with the end of shifting axle 17, and the end in addition of this shifting axle 17 also is provided with actuation gear 18.Like this, when magnetic switch is opened, this coil unit 19 will produce magnetic force and drive that iron core 13 overcomes the elastic force of spring and to the right motion as shown in Figure 1, this moment, shift fork 16 upper ends also moved right under the drive of iron core 13, these shift fork 16 lower ends then promote shifting axle 17 simultaneously, and this shifting axle 17 is moved the actuation gear 18 phase left sides; This moment is because the effect of coil unit 19, this actuating motor 11 begins rotation, but because this electric current is very little, so actuating motor 11 slowly rotates, also drive actuation gear 18 and slowly rotate, and mesh gradually with the engine flywheel 30 on the left side, when both mesh fully, actuating motor 11 main circuits are switched on, and actuating motor 11 will rotate with working speed, and pilot engine.This moment, this engine flywheel 30 can make overrunning clutch skid, thereby made actuation gear 18 break away from flywheel 30.Close magnetic switch this moment, and so make iron core 13 reset under the effect of Returnning spring 15, actuation gear 18 is also return simultaneously, thereby make starter motor 100 quit work and wait for next time and to start.
But, the fulcrum of these starter motor 100 shift forks 16 is to determine by the special-shaped torsion spring 20 of winding on iron core 13, its working procedure specifically as shown in Figures 2 and 3, because these abnormity torsion spring 20 shapes, size and elastic force all are difficult to control, so this fulcrum also has unstability, thereby cause the position of switch main contact shift fork 16 fulcrums when connecting also to have unstability, make and finally have influence on the engagement situation between starter motor 100 actuation gears 18 and the engine flywheel 30 by the pressure transient that acts on actuation gear 18 end faces.
In view of this, the inventor has this case to produce at the above-mentioned defective further investigation of shift fork 16 fulcrums of existing starter motor 100 then.
The model utility content
The purpose of this utility model is to provide a kind of starter motor shift fork fulcrum structure, stablizes and then influence the problem of engagement situation between actuation gear and the engine flywheel inadequately with shift fork fulcrum in the solution prior art.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of starter motor shift fork fulcrum structure, be useful on the starter motor with protecgulum and support this shift fork, wherein, this protecgulum is formed with receiving groove, the opening of this receiving groove is towards the movement direction that is parallel to shifting axle, and this shift fork fulcrum structure comprises support block, spiral compression spring, straight pin and spring press-cover; One end of this support block is formed with the flange that slides and fit with receiving groove, settles out under the other end end face to extend axially and the ccontaining locating slot of confession shift fork along support block, and the pin-and-hole that is communicated with this locating slot is also run through in this support block the other end side; This spiral compression spring is set on the support block, and two ends are resisted against respectively on support block flange and the spring press-cover; This straight pin runs through in the mounting hole of this pin-and-hole and shift fork; One end of this spring press-cover is resisted against on the protecgulum, and the other end also has receiving hole that is inserted in for this support block locating slot one side and the breach that communicates and supply shift fork to pass with this receiving hole.
Further, this breach extends axially setting along spring press-cover whole.
After adopting said structure, fulcrum in the starter motor shift fork fulcrum structure that the utility model relates to is straight pin, its concrete position is controlled by spiral compression spring, because the geomery and the elastic force of this spiral compression spring all are easier to be controlled by people, so the utility model can make position of the fulcrum stable and the shift fork Stroke Control is easy, thereby guarantee the stability that meshes between actuation gear and the engine flywheel.
