Abstract
The utility model discloses a kind of many brushes parallel shunt reversing arrangement of AMT motor, comprise commutator and multiple brush, brush is provided with brush pigtail, brush contacts with commutator, described brush is evenly distributed on around commutator, adjacent a part of brush passes through brush pigtail connect in parallel thus forms a pole of current path, and adjacent another part brush passes through brush pigtail connect in parallel thus forms another pole of current path.The utility model can reduce the current density of single brush, even acting force of the spring, thus reduces the generation of spark, reduces the wearing and tearing of brush.
Description
Technical field
The utility model relates to a kind of many brushes parallel shunt reversing arrangement of AMT motor, belongs to brush motor technical field.
Background technology
AMT motor is the important functional part of in automotive transmission, general motor majority is that only employing 2 or multiple brush commutate separately, without in parallel, this structure causes the electric current of single brush larger on the one hand, easy generation spark, on the other hand when acting force of the spring is uneven, wear of brush is serious.
Summary of the invention
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, there is provided a kind of many brushes parallel shunt reversing arrangement of AMT motor, it can reduce the current density of single brush, even acting force of the spring, thus reduce the generation of spark, reduce the wearing and tearing of brush.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of many brushes parallel shunt reversing arrangement of AMT motor, comprise commutator and multiple brush, brush is provided with brush pigtail, brush contacts with commutator, described brush is evenly distributed on around commutator, and adjacent a part of brush passes through brush pigtail connect in parallel thus forms a pole of current path, and adjacent another part brush passes through brush pigtail connect in parallel thus forms another pole of current path.
Further, described brush is at least provided with four.
Further, the brush of described connect in parallel has two at least.
After have employed technique scheme, adjacent brush of the present utility model is by brush pigtail connect in parallel, the electric current of two interpolars is shunted through multiple brush, thus reduces the current density of single brush, decreases the generation of spark, simultaneously, in motor, the active force of spring is evenly distributed on multiple brush, decreases the wearing and tearing of single brush, makes brush-commutated more stable, electrical machinery life doubles, and motor noise reduces.
Accompanying drawing explanation
Fig. 1 is the structural representation of many brushes parallel shunt reversing arrangement of the utility model AMT motor;
In figure, 1, brush, 1-1, brush pigtail, 2, commutator.
Embodiment
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail,
As shown in Figure 1, a kind of many brushes parallel shunt reversing arrangement of AMT motor, comprise commutator 2 and multiple brush 1, brush 1 is provided with brush pigtail 1-1, brush 1 contacts with commutator 2, brush 1 is evenly distributed on commutator 2 around, and adjacent a part of brush 1 passes through brush pigtail 1-1 connect in parallel thus forms a pole of current path, and adjacent another part brush 1 passes through brush pigtail 1-1 connect in parallel thus forms another pole of current path.
As shown in Figure 1, described brush 1 is provided with four, can certainly be provided with six.
As shown in Figure 1, the brush 1 of described connect in parallel has two, can certainly have three.
Adjacent brush of the present utility model is by brush pigtail connect in parallel, the electric current of two interpolars is shunted through multiple brush, thus reduce the current density of single brush, decrease the generation of spark, meanwhile, in motor, the active force of spring is evenly distributed on multiple brush, decrease the wearing and tearing of single brush, make brush-commutated more stable, electrical machinery life doubles, and motor noise reduces.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that the utility model solves are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
Claims (3)
