Description
Technical field
The utility model relates to technical field of automobile, is specifically Novel starter.
Background technology
Starter is motor again, and the electric energy conversion of storage battery is mechanical energy by it, is widely used in automobile manufacturing field.
The starter of prior art, in order to reach the effect of reversion, just needs on the basis rotating forward starter, stator is made reversion with regard to enough, ensures the reversion of starter with this.But stator is too expensive, and volume is heavy greatly.So at production link, in order to meet manufacture requirements, often need the reversion stator that stock is a large amount of, such stock brings huge warehousing pressure to manufacturing enterprise.And stator will be made reversion stator and the structure of stator can be allowed to become more complicated, cause production cost to increase, production efficiency is lower.
Summary of the invention
In view of the defect of above-mentioned prior art, the purpose of this utility model is: provide a kind of structure simple and can compared with the Novel starter of low production cost.
Technical solution of the present utility model is: a kind of Novel starter, comprise casing, armature shaft, the armature being arranged on the end cap at casing two ends and bonnet respectively and being arranged in casing, one end of described armature is provided with commutator, and the outside wall surface of this commutator is evenly distributed with multiple commutator segment, it also comprises a brush holder, described brush holder comprises brush rack base and is arranged on the multiple brush carrier blocks on brush rack base, and each brush carrier block is fixed with brush holder support, one end of each brush holder support is provided with one or more brush carrier, and brush is inserted with on brush carrier, described brush spring compression, one end of described brush and the commutator segment sliding contact of commutator.
Further, described brush rack base ringwise, and is fixed in bonnet.
Further, the quantity of described brushgear housing is four, and is evenly distributed on brush rack base.
Further, the brush quantity that each brush carrier plugs is two, and brush is cuboid brush.
Further, the internal face of described casing is evenly provided with multiple permanent magnet pole.
Further, described armature is axially disposed within armature shaft, and the outside wall surface of armature is provided with multiple groove, and winding is provided with winding in groove.
Further, it also comprises a spring bearer plate, and it is arranged on brush holder.
Further, described end cap is square end cap, and is provided with installing hole on four angles of end cap, and the center of end cap is provided with the axis hole passed for armature shaft one end.
Apply a kind of Novel starter provided by the utility model, its beneficial effect is: brush and commutator with the use of, can keep the compatibility of stator, namely no matter starter rotates forward or reversion, and stator is general, and just reverse function is realized by brush holder, brush holder relative inexpensiveness, cost is 10% ~ 20% of stator, and volume and weight more only has less than 10% of stator, thus make the structure of starter become simple, greatly reduce the manufacturing cost of starter.

Embodiment
For more intuitively, intactly understanding the technical solution of the utility model, existing just to carry out nonrestrictive feature description in conjunction with the utility model accompanying drawing as follows:
As depicted in figs. 1 and 2, a kind of Novel starter, the armature 5 comprising casing 1, armature shaft 2, the end cap 3 being arranged on casing 1 two ends respectively and bonnet 4 and be arranged in casing 1, one end of armature 5 is provided with commutator 6, and the outside wall surface of this commutator 6 is evenly distributed with multiple commutator segment 7; It also comprises a brush holder 8, brush holder 8 comprises brush rack base 9 and is arranged on the multiple brush carrier blocks 10 on brush rack base 9, and each brush carrier block 10 is fixed with brush holder support 11, one end of each brush holder support 11 is provided with one or more brush carrier 12, and brush 13 is inserted with on brush carrier 12, brush 13 spring compression, by the pressure of spring, one end of brush 13 and commutator segment 7 sliding contact of commutator 6.
Brush rack base 9 ringwise, and is fixed in bonnet 4, and accordingly, bonnet 4 is cylindrical, so just brush rack base 9 firmly can be fixedly connected with bonnet 4.
The quantity that brush is 13 is four, and is evenly distributed on brush rack base 9; Brush 13 quantity that each brush carrier 12 plugs is two, and brush 13 is cuboid brush 13.Brush 13 loads in brush carrier 12 and will guarantee freely up and down to move, and the gap of brush 13 side and brush carrier 12 inwall should between 0.1 ~ 0.3 millimeter, in order to avoid brush 13 is stuck in brush carrier 12 produce swing in response to excesssive gap, so brush 13 manufactures cuboid.Brush carrier 12 lower edge should ensure within the scope of 2 ~ 3 millimeters apart from the distance on commutator 6 surface, and it is apart from too small, and brush carrier 12 easily touches hinders commutator 6, and brush 13 also may be caused to be stuck in brush holder 8, and spring cannot compress brush 13, and machine operation loses meaning; Excesssive gap, brush 13 can produce swing in frame, easily causes damaging not only occurring noise, the more important thing is and occurs spark, cause a devastating effect to commutator 6.
The internal face of casing 1 is evenly provided with multiple permanent magnet pole 14, for generation of air-gap field.
Armature 5 axle 2 is to being arranged on armature 5 axle 2, and the outside wall surface of armature 5 is provided with multiple groove, and winding is provided with winding 15 in groove, and winding 15 can produce electromagnetic torque and induced electromotive force.It is formed by connecting according to certain rules by many coils, and coil adopts high strength enamelled wire or glass fiber bag flat type copper wire to be coiled into, and the coil side of different coil divides two-layer up and down embedding in armature 5 groove.
This starter also comprises a spring bearer plate 16, and it is arranged on brush holder 8, for propping up spring, and allows brush 13 keep certain contact on commutator 6.
Described end cap 3 is square end cap 3, and installing hole is provided with on four angles of end cap 3, and the center of end cap 3 is provided with the axis hole passed for armature shaft 2 one end, square end cap 3 conveniently can offer installing hole and fixing hole on end cap 3, and axis hole can allow armature shaft 2 keep stable.
A kind of Novel starter provided by the utility model, brush 13 and commutator 6 with the use of, the compatibility of stator can be kept, namely no matter starter rotates forward or reversion, stator is general, and just reverse function is realized by brush holder 8, certainly, in use, the lead-in wire of each brush 13 electric wire can be exchanged and install, reversion control assembly also can be installed on brush holder 8, reversion can be realized, brush holder 8 relative inexpensiveness, cost is 10% ~ 20% of stator, volume and weight more only has less than 10% of stator, thus make the structure of starter become simple, greatly reduce the manufacturing cost of starter.
Certainly; these are only preferred embodiment of the present utility model; non-ly therefore namely limit to the scope of the claims of the present utility model, all utilization the utility model specifications and graphic content institute be simple and easy modification and equivalent structure change for it, all should in like manner be contained within scope of patent protection of the present utility model.
