Referring to Fig. 4, and combine Fig. 3,5,6, on the path back segment 30b of push rod 30, be set with sleeve 20, at the mount pad 28 of sleeve 20 rear sides, compression spring 22 between sleeve 20 and mount pad 28.
As a kind of embodiments possible, sleeve 20 can be processed by magnetic shielding material or the ambroin that contains magnetic shielding material.Adopt magnetic shielding material, can make push rod that the influence of magnetic circuit is reduced.
It is roughly cylindric that sleeve 20 is, and has middle heavy wall section 20a and the thin segment 20b that is positioned at sleeve 20 axial both sides.The step surface 20c of the axis normal of formation and sleeve 20 between middle heavy wall section 20a and each the thin segment 20b.Two thin segment 20b preferably have mutually the same shape and size, so that sleeve 20 has symmetrical structure in the vertical, thereby are convenient to the installation of sleeve 20 on path back segment 30b (needn't consider sleeve 20 towards).
Like Fig. 3, shown in 4; The internal perisporium of the middle heavy wall section 20a of sleeve 20 is matched with on the path back segment 30b slidably; Be positioned at the rearward end of the thin segment 20b of front side, between the thin segment 20b of rear side and path back segment 30b, limit the voltage supply annular accommodation space that the front portion of spring 22 inserts that contracts round big footpath leading portion 30a.In addition, the step surface in the front side of sleeve 20 is resisted against the transition shoulder between big footpath leading portion 30a and the path back segment 30b, and the step surface that is positioned at rear side is compressed the front end pushing and pressing of spring 22.The rear end of compression spring 22 pushes against in the front end face of mount pad 28.

Be held under the state of push rod 30 rear ends by aforesaid mode at contact bridge 14; Push rod 30 can resisted the thrust of compressing spring 22 and on the path back segment 30b of push rod 30, axially move forward (slip), but its moving backward stops fastener 42.
Be appreciated that utilization such as securing members such as nut 42 and mount pad 28 only are exemplary with the mode that contact bridge 14 is held on push rod 30 rear ends.At this, any permission contact bridge 14 moves forward on push rod 30 but stops its structure and element of moving backward to adopt.
In addition, intermediate flange 28b be sized to be suitable for getting among the backstop groove 4d of fixed iron core 4 and by backstop in this.
In addition, as shown in Figure 3, compression spring 24 is housed between moving core 16 and fixed iron core 4.The front end of this compression spring 24 is arranged in spring storage tank 16b and pushes against in the bottom of spring storage tank 16b.The middle part of this compression spring 24 and rear sleeve are located on the front side thin segment 20b and middle heavy wall section 20a of sleeve 20.The rear end of this compression spring 24 pushes against in the front end face of fixed iron core 4 (being the front end face of mating part 4c).
Like descriptions of back institute, said compression spring 22 compresses the back-moving spring that spring 24,26 is used as push rod 30 as the back-moving spring of contact bridge 14.Just can provide at compression spring 24 itself under the situation of enough reset force, can omit and compress spring 26 for push rod 30.
When assembling electromagnetic switch shown in Figure 3, can be with lining 32 and solenoid 6 to be installed in the housing 2 fixed iron core 4 earlier; Be with push rod 30, sleeve 20, compression spring 24 from the front side is packed housing 2 into moving core 16 again, making the rear end of push rod 30 pass fixed iron core 4 and expose from the rear end of housing 2; Then, to push rod 30 compression spring 22, mount pad 28, contact bridge 14 and securing member 42 are installed from rear side; Then, be with two binding posts 10 to be installed on the housing 2 from rear side cap 8, compression spring 26 is installed between the rear end and cap 8 of push rod 30 (being inserted among the spring storage tank 8a).Can find out that the electromagnetic switch of the utility model can be assembled with easy mode, installation process and prior art are basic identical.
The operation of the vehicle starter and the electromagnetic switch thereof of the utility model is described below.
After starting vehicle through ignition switch; The solenoid 6 of electromagnetic switch is powered; The two flow direction of solenoid 6 hold-in windings and pull in winding is identical; Mutually stack, thus in moving core 16, produce forceful electric power magnetic force, with moving core 16 with push rod 30 and resisting the thrust of spring 24,26 and move towards fixed iron core 4 (backward); The front end of push rod 30 is through shift fork (not shown) pulling transmission mechanism, so that the direction (forward) of the gear ring of its driven wheel on engine flywheel moves; The rear end band of push rod 30 contact bridge 14 and is moved towards two binding posts 10.Afterwards, contact bridge 14 touches two binding posts 10, and with the two electrical connection.Like this, make the main circuit of motor connect, so that the motor rotation through these two binding posts 10.With after two binding posts 10 are realized contacting; Contact bridge 14 promptly is prevented from and can not continues to move backward; And push rod 30 is being resisted the thrust of spring 22,24,26 and continue backward to move; Push against in fixed iron core 4 until moving core 16, promptly the mating part 4c of fixed iron core 4 engages with the mating groove 16c of moving core 16.Simultaneously, in the process that moving core 16 moves backward, the gear ring on driven wheel and the engine flywheel meshes, and thus rotatablely moving of motor is delivered to engine flywheel, with engine start.
After engine start, in the moment of unclamping ignition switch, the two magnetic flux of the hold-in winding of solenoid 6 and pull in winding is cancelled out each other, thereby the electromagnetic force that in moving core 16, produces disappears.Moving core 16 under the effect of reset force of compression spring 24,26 effect of spring 22 (even compress in addition) move forward, thereby through shift fork driven wheel is pulled away from the gear ring on the engine flywheel.After push rod 30 had moved forward a bit of distance, securing member 42 touched contact bridge 14 and it is pulled away from two binding posts 10, breaks off the main circuit of motor thus, thereby starter is shut down.The intermediate flange 28b of mount pad 28 get among the backstop groove 4d of fixed iron core 4 and by backstop in after this, moving forward of moving core 16 is terminated.
When contact bridge 14 is pulled away from two binding posts 10; Push rod 30 receives the reset force forward that back-moving spring 24,26 is produced; This reset force is enough to make contact bridge 14 to separate fast from two binding posts 10, thereby avoids generating material adhesion between contact bridge 14 and the binding post 10 (this material adhesion might cause binding post to be ablated).
In the process that push rod 30 moves forward and backward, sleeve 20 slides in the guide through hole 4e of fixed iron core 4, thereby push rod 30 is played the effect of supporting and leading.In addition, in the process that push rod 30 moves forward and backward, the major part of sleeve 20 is in solenoid 6 restricted portions in the axial direction.
Can see, compare with prior art shown in Figure 2 that in the electromagnetic switch of the utility model shown in Fig. 3, sleeve 20 has the diameter of increase, this just requires the diameter of the guide through hole 4e of fixed iron core 4 correspondingly to increase.The result; Space between the outer peripheral face of the path back segment 30b of the internal perisporium of the guide through hole 4e of fixed iron core 4 and push rod 30 increases; So that the magnetic gap between fixed iron core 4 and the push rod 30 strengthens; Thereby the influence of the magnetic circuit that 30 pairs of solenoids of push rod 6 produce reduces, and this makes that utilizing magnetic material to process push rod 30 becomes possibility.
Therefore, according to an importance of the utility model, push rod 30 is processed by magnetic material.This magnetic material can be steel.With the nonmagnetic substance of available technology adopting for example copper, copper alloy, stainless steel etc. compare, adopt steel to reduce cost, can satisfy the mechanical performance requirement of push rod simultaneously, and improve machinability.
It will be understood by those skilled in the art that by attribute classification, steel comprise substantially: ordinary steel (P≤0.045%, S≤0.050%); (2) excellent steel matter steel (P, S are all≤0.035%); (3) senior high-quality steel (P≤0.035%, S≤0.030%).
Adopt, ordinary steel (for example 10# steel) can be so that the push rod cost be minimum, and the mechanical performance of push rod itself still can satisfy.In addition, the structure of electromagnetic switch itself and assembling mode do not need obvious change.
In addition, limit the contract annular accommodation space of insertion of spring 22 of voltage supply between the path back segment 30b of the thin segment 20b of sleeve 20 and push rod 30.Like this; The part of compression spring 22 is maintained at this accommodation space; Thereby improved the stability of compression spring 22 widely, to guarantee that compressing spring 22 can not avoid causing that because of compression spring 22 touches fixed iron core 4 magnetic circuit is interfered because of distortion touches fixed iron core 4 like this.
In sum, the utility model provides a kind of improved tube-in-tube structure, make push rod can by magnetic material for example ordinary steel process.
Be appreciated that above-mentioned sleeve and the dependency structure of describing with reference to Fig. 3 can use with various forms of push rod combinations.
For example, in example shown in Figure 3, the big footpath leading portion 30a and the path back segment 30b of push rod 30 form.Yet; As another kind of feasible pattern; Big footpath leading portion 30a can form independent of one another, be connected to path back segment 30b, and promptly push rod 30 has two-part structure (be fixed on the first bar section on the moving core and be installed in the second bar section in the fixed iron core movably).For example, can pass through the connection that sleeve 20 is realized between two bar sections, and sleeve 20 can be constructed with releasable syndeton, for example claw.In addition, sleeve 20 can be configured such that and can have a bit of distance that moves axially against each other between two bar sections.
In addition, above-mentioned sleeve and the dependency structure of describing with reference to Fig. 3 can also be used for the electromagnetic switch of prior art shown in Figure 1 is transformed.
For example, the sleeve 20 among Fig. 1 can increase external diameter equally, and forms the guide through hole of the corresponding increasing of diameter in the fixed iron core 4.Simultaneously, form similar thin segment, the part of compression spring 22 is inserted in the accommodation space that limits between this thin segment and the push rod 12.In this case, push rod 12 can by magnetic material for example ordinary steel process.In addition, push rod 12 can be realized being connected with push rod 18 through sleeve 20.In this case, can think that push rod 18 and push rod 12 constitute the first bar section and the second bar section of segmented push rod.
Though described the utility model, the details shown in the scope of the utility model is not limited to reference to concrete execution mode here.Under the situation of the basic principle that does not depart from the utility model, can make various modifications to these details.
