The utility model discloses utilize reverse coil to produce and inhale and draw the coil and keep the reverse magnetic field of coil to reach quiet iron core and move the effect that the iron core homopolar is exclusive mutually, consequently can cushion effectively and move the impact force that the iron core produced to quiet iron core, realize extension starter life's purpose.

Description

Integrated starter electromagnetic switch assembly

Technical Field

The utility model relates to an integral type starter electromagnetic switch subassembly.

Background

When the heavy-duty speed-reducing starter with the traditional structure is started, the suction force generated by the suction coil of the switch pushes the driving gear to extend out of the soft meshing flywheel through the shifting fork. However, some starters do not adopt a structure that a shifting fork toggles a driving gear due to the requirement of structure simplification or installation, the driving gear is pushed to extend out by only depending on the magnetic field suction force generated by a pull-in coil, at the moment, the pull-in coil needs to realize that the driving gear is in soft meshing with a flywheel through a considerable current, and the pull-in coil generates a large magnetic field to generate a large suction force.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: in order to overcome not enough among the prior art, the utility model provides a can effectively cushion and move iron core impact force, extension starter life's integral type starter electromagnetic switch subassembly.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an integral type starter electromagnetic switch subassembly, includes the front end housing of starter, locates the drive shaft at front end housing inner chamber center and installs the drive gear at the drive shaft tip, installs the iron core that moves that encircles the drive shaft in the front end housing inner chamber, and move the iron core front end interval and be equipped with quiet iron core, be located and move the iron core periphery and install the suction coil of clockwise coiling through the coil skeleton, suction coil periphery be equipped with the holding coil of clockwise coiling, encircle the reverse coil that quiet iron core tip was equipped with anticlockwise coiling.

Preferably, the coil bobbin is divided into 1: the ratio of 8 is divided into a small section and a large section, the pull-in coil and the holding coil are positioned in the large section, and the reverse coil is positioned in the small section.

The utility model has the advantages that: the utility model discloses utilize reverse coil to produce and inhale and draw the coil and keep the reverse magnetic field of coil to reach quiet iron core and move the effect that the iron core homopolar is exclusive mutually, consequently can cushion effectively and move the impact force that the iron core produced to quiet iron core, realize extension starter life's purpose.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1, the integrated starter electromagnetic switch assembly comprises a front end cover 1, a driving shaft 2 arranged at the center of an inner cavity of the front end cover 1, and a driving gear 3 arranged at the end part of the driving shaft 2, wherein a movable iron core 4 surrounding the driving shaft 2 is arranged in the inner cavity of the front end cover 1, a static iron core 5 is arranged at a distance from the front end of the movable iron core 4, and a return spring 10 for returning the movable iron core 4 after starting is arranged on the static iron core 5.

Be located 4 peripheries of movable iron core and extend to 5 tip of quiet iron core and be equipped with coil skeleton 6, coil skeleton 6 with 1: the proportion of 8 is divided into a small section and a large section, wherein the small section is positioned at the end part of the static iron core 5, the large section of the coil framework 6 is provided with a pull-in coil 7 wound clockwise, the periphery of the pull-in coil 7 is provided with a holding coil 8 wound clockwise, and the small section of the coil framework 6 is internally provided with a reverse coil 9 wound anticlockwise and surrounding the end part of the static iron core 5.

The utility model discloses divide into starter control part and keep coil 8 and inhale and draw coil 7 two sets of, coil skeleton 6 is with 1: the proportion of 8 is divided into a small section and a large section, after the suction coil 7 is wound in the large section of the coil framework 6, the holding coil 8 is continuously wound around the periphery of the suction coil 7 clockwise, and after the winding is finished, about thirty-turn reverse coils 9 are reversely wound in the small section of the coil framework 6.

The reverse coil 9 is arranged at the end part of the static iron core 5, when the starter is started, the reverse coil 9 generates a magnetic field which is opposite to the pull-in coil 7 and the holding coil 8, so that the effect that the static iron core 5 and the movable iron core 4 repel each other in the same pole is achieved, the impact force generated by the movable iron core 4 on the static iron core 5 during starting can be effectively buffered, and the purpose of prolonging the service life of the starter is achieved.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
