The rare earth permanent magnetic reduce starting motor comprises an armature, a one-way clutch, a reducer, a driving end cap, a brush cover and a shifting fork in the prior art. The automobile used rare earth permanent magnetic reduce starter is characterized in that the stator is provided with an exciting rare earth neodymium-iron-boron (NdFeB) permanent magnet; a quasi-integral electromagnetic switch is adopted; the neodymium-iron-boron (NdFeB) permanent magnet is tile shaped, and uniformly fixed and clamped on the circumferential surface inside the casing through six elastic clamping pieces; the quasi-integral electromagnetic switch adopts the structure that a slideable movable iron core assembly and a spring are installed inside an exciting coil assembly, and the post rod assembly can be relatively displaced in the movable iron core assembly. The rare earth permanent magnetic reduce starting motor has the advantages that the structure is compact, the volume of the entire motor is greatly reduced, the weight is reduced, the starting torque is increased, the power range is expanded, the specific power, the durability and the performance-to-price ratio are improved, the probability of switch conglutination is reduced, and the reliability of the starter is enhanced.
Description
Technical field
The utility model belongs to combustion engine starting technique field, relates to a kind of rare earth permanent magnet slowdown type actuating motor that has accurate integral type electromagnetic switch, and international Patent classificating number is: F02N11/00.
Background technology
The magnetic field of tradition starter is produced by the magnetizing coil that is loaded on the stator, and shortcoming is that specific power is lower, volume and weight are bigger.
At present existing motorcar engine uses the ferrite permanent-magnet retarding starter, and the ferrite permanent-magnet starter has replaced magnetizing coil in the electric excitation type starter with the ferrite permanent-magnet magnetic pole, has dwindled volume, has reduced copper consumption, and specific power is improved.But because the remanence strength and the magnetic energy product of ferrite permanent-magnet materials is not high, limited the power bracket that it is used in starter, only be used for the starter about power 1.0kw at present.The ferrite permanent-magnet starter adopts split type electromagnetic switch, and reliability is lower.
Summary of the invention
The purpose of this utility model just is to provide the automobile-used rare earth permanent magnet retarding starter that a kind of volume is littler, more powerful, improve starting performance.
The purpose of this utility model is achieved in that it comprises armature, one-way clutch, decelerator, driving end cap, brush cover and the shift fork of prior art.
Be characterized in:
1, stator is installed rare-earth Nd-Fe-B (NdFeB) permanent magnet of excitation;
2, adopted accurate integral type electromagnetic switch.
Described rare-earth Nd-Fe-B (NdFeB) permanent magnet is a watt shape, and 6 pieces watts of shape NdFeB permanent magnets evenly are clipped on the casing inner circumferential surface by 6 elastic clips admittedly;
The structure of described accurate integral type electromagnetic switch is: the magnetizing coil assembly of prior art and switch cover assembly, link together with screw by sealing ring, in switch cover assembly inside push rod assembly and spring are installed, be characterized in: in magnetizing coil assembly inside the assembly moving unshakable in one's determination and the spring that can slide is housed, the push rod assembly can have certain relative displacement in moving assembly unshakable in one's determination inside.
The course of work of accurate integral type electromagnetic switch of the present utility model is:
Logical 12V of magnetizing coil or 24V direct current, the magnetizing coil of switch inside produces magnetic field, moving assembly unshakable in one's determination is behind the segment distance that inwardly slides under the effect of magnetic field force (being push rod assembly and the gap of moving assembly unshakable in one's determination inside), the push rod assembly is promoted forward, make contact copper coin and two output screw termination contact on the push rod assembly.
The utility model has the advantages that:
1, adopt rare-earth Nd-Fe-B (NdFeB) permanent magnet excitation of high magnetic characteristics, compact conformation, machine volume greatly reduces, weight saving, starting torque increases, and power bracket enlarges, and specific power and durability and cost performance improve greatly.
2, adopt accurate integral type electromagnetic switch, significantly reduced the probability of failure of switch adhesion, greatly improved the reliability of starter.
