Abstract
The invention provides an electric brush carrier assembly for a starting engine. The electric brush carrier assembly comprises an electric brush bottom plate, four brush carriers, brush springs and electric brushes, wherein the four brush carriers are arranged on the electric brush bottom plate in a pairwise opposite manner; the electric brushes are arranged in the brush carriers; the brush carriers are hollow injection moldings of which the front ends are open; the brush springs are cylindrical springs and are arranged in the four brush carriers respectively; one end of each spring acts on the back wall of the corresponding brush carrier, and the other end of each spring acts on the corresponding electric brush; the other end, i.e. the front end face, of each electric brush acts on the outer circle of a reverser; and a lead-out wire of each electric brush projects out of the side wall of the corresponding brush carrier. Due to the adoption of the electric brush carrier assembly, the maintenance frequency and the maintenance cost are reduced remarkably, and resource waste is effectively reduced.
Description
Technical field
The invention belongs to technological transformation, be specifically related to the brush carrier assembly of starter starter.
Background technology
The starting of petrol engine or Diesel engine is started by starter.The starter course of work is: connect ignition switch, electromagnetic switch sucking coil and hold-in winding are switched on simultaneously, and under the electromagnetic force effect, moving iron core and shift fork move, and drive isolator and gear move forward and mesh with flywheel ring gear.Starter major failure on the engine is a burn-down of electric motor at present, summarize according to motor being simulated the test of on car load, not cutting off the power supply, and the fault motor analyzed, its main failure mode is that motor works long hours or abnormal work causes the armature temperature to raise to be short-circuited fault and armature commutator to jump row.Used armature frame assembly comprises the brush base plate, is arranged on four brush holders facing each other on the brush base plate in the starter now, torsion spring and the brush that is installed in the brush holder, wherein brush holder is a metal shell, torsion spring is fixed on the brush base plate, because torsion spring and metal brush holder resistance to elevated temperatures are good, when starter generation abnormal work causes short circuit, easily cause the external circuit ablation, last even cause phenomenon of the failure on fire, bring tremendous loss to the car owner.
Summary of the invention
For overcoming the deficiencies in the prior art, the brush carrier assembly that provides a kind of novel starter simple in structure, that production cost is low to use, it can guarantee that starter can not cause the outside line related phenomenon that is short-circuited under the situation that the car load circuit abnormal is not cut off the power supply.
For achieving the above object, the present invention is achieved through the following technical solutions: a kind of brush carrier assembly of starter, comprise the brush base plate, be arranged on four brush holders facing each other on the brush base plate, brush spring and the brush that is installed in the brush holder, described brush holder is the hollow moulding of front opening, described brush spring is that cylindrical spring and its are installed in respectively in four brush holders, described spring one end acts on the rear wall of brush holder, the other end acts on brush, the other end of described brush is that front end is end-acted on the commutator cylindrical, and the lead-out wire of described brush passes from the sidewall of brush holder.
As a further improvement on the present invention, for easy for installation, quick, increase work efficiency, described brush plate in the form of a ring and have a plurality of contact arms that brush holder is used that are used to install, be respectively equipped with chute on the two side of described brush holder, install when connecting, the contact arm that is arranged in the brush holder left and right sides embeds chute, and the contact arm that is positioned at the forward and backward two ends of brush holder is bent upwards and acts on the two ends of brush holder respectively.
In order to improve thermal endurance, have louvre on the rear wall of described brush holder at the situation lower brush frame assembly of operate as normal.
The present invention passes through the structure to structure that changes brush carrier and brush spring, makes whole brush carrier assembly reach following effect:
1, motor can make the brush spring lose efficacy at the high temperature that continues the energising generation, and makes the motor outage;
2, high temperature after taking place in motor, and the bakelite brush holder after the improvement opens circuit motor than the easier inefficacy of virgin metal brush holder.
By above-mentioned two improvement, make under the electric motor abnormality situation and big electric current can not take place, thereby truly reach the situation that motor can not cause the interlock circuit ablation causes on the car load car load to catch fire after motor opens circuit under the situation of unusual energising, improved fail safe; Simultaneously because during something unexpected happened, motor internal only takes place to open circuit and quit work, significantly reduced maintenance, maintenance cost, reduced the waste of resource effectively.

Among the figure, 1 is the brush base plate; 11 is contact arm; 2 is brush holder; 21 is louvre; 22 is chute; 23 is lead-out groove; 3 is spring; 4 is brush; 5 is commutator; 6 is the brush lead-out wire.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing and specific embodiment.
Embodiment, as shown in Figure 1 and Figure 2: the brush carrier assembly that the present invention relates to a kind of engine, comprise brush base plate 1, four brush holders 2, four cylindrical springs 3 and four brushes 4, wherein: brush holder 2 is the hollow moulding of front opening, and relative fixed is on brush base plate 1 in twos for described four brush holders 2, and cylindrical spring 3 is installed in the brush holder 2, the one end acts on the rear wall of brush holder 2, and the other end acts on brush 4; Brush 4 is installed in the brush holder 2, and it is end-acted on commutator 5 cylindricals that its front end is exposed at the outside and the front end of brush holder 2, and the lead-out wire 6 of brush passes from the lead-out groove on the brush holder sidewall.
As shown in figures 1 and 3: described brush base plate 1 is structure and have a plurality of contact arms 11 that brush holder is used that are used to install in the form of a ring; As shown in Figure 3, be respectively equipped with the lead-out groove 23 of chute 22 and brush lead-out wire on the two side of brush holder 2, the rear wall of brush holder 2 is provided with louvre 21; Install when connecting, the contact arm 11 that is arranged in brush holder 2 left and right sides embeds chute 22, and the contact arm 11 that is positioned at the forward and backward two ends of brush holder is bent upwards and acts on the two ends of brush holder 2 respectively.
After brush carrier assembly after improving is assemblied in motor, on car load, carry out destructive testing, the result shows: the pattern that armature lost efficacy all is that the brush carrier assembly damages or commutator copper bar is at high temperature jumped out a row, brush or brush carrier are broken, the motor inefficacy of opening circuit, and big electric current does not take place in entire test.
