The automotive alternator and its brush assembly of electric of energy.
Background technology
It is known that for brushing hair motor, slip ring in brush assembly of electric in REG Regulator Assembly and rotor assembly it
Between the contact important ring that is connected as in energized circuit.In generator normally runs, slip ring constantly turns with rotor assembly
Dynamic, the brush in brush assembly of electric can be worn and torn due to machinery and electricabsorption agent, when brush wear totally when, the shunt welding quilt of brush
Stretch, brush there will be the situation of virtual connection with the connection of slip ring, can so cause the generation of electric arc so as to destroy slip ring surface light
Cleanliness.It needs when safeguarding to change rotor assembly and brush assembly of electric the generator for so damaging, and safeguards inconvenient and high cost.
Specifically, as shown in figure 1, Fig. 1 is prior art electric generator structure schematic diagram.Generator generally include drive end bearing bracket 1,
Field frame assembly 2, rotor assembly 3, rear end cap 4, REG Regulator Assembly 5, shield 6, rectifier stack assembly 7, rear bearing 8, fore bearing 9 with
And belt pulley 10.Referring to Fig. 2 a and Fig. 2 b, REG Regulator Assembly 5 includes closure 501, regulator bracket 502, the and of spring 503
Brush assembly of electric 504.Wherein brush assembly of electric 504 includes brush body 504a and the shunt welding 504b (conduction materials being connected on brush body 504a
Matter), shunt welding 504b passes through spring 503, is placed on jointly in regulator bracket 502.Regulator chip, associate conductive lead etc. are all
In installing or being embedded in regulator bracket 502.Shunt welding 504b is through the reserved shunt welding hole 502a of regulator bracket 502 and is welded on
On pre-buried leader 502b, pre-buried leader 502b is respectively positive and negative two-stage and (and is connected with upper and lower two sets of brushes, due to its connection side
Formula and physical arrangement are consistent, and the concrete structure of one of them is only introduced herein).During normal use, spring 503 will
Brush ejection regulator bracket 502 makes brush body 504a and slip ring joint, and keeps certain contact force.But brush assembly of electric 504
Brush body 504a when wearing up to root shunt welding 504b will be straightened so as to prevent brush body 504a from further contacting slip ring, due to shunt welding
Some is filled in brush body 504a 504b, and shunt welding 504b and slip ring directly contact will cause the abrasion of slip ring, therefore
REG Regulator Assembly 5 limits the ejection length of brush body 504a by adjusting the length of shunt welding 504b when manufacturing.Although can so prevent
Only abrasions of the landfill part shunt welding 504b to slip ring, but shunt welding 504b is stretched, when limitation brush body 504a is outwards ejected, brush body 504a
Can be because loose contact produces electric arc, so as to cause slip ring contact surface to sustain damage between slip ring.
