Abstract
The invention discloses an automobile starting motor carbon brush with holes. The automobile starting motor carbon brush with the holes is composed of a left carbon body, a right carbon body, a left carbon brush wire, a right carbon brush wire and an angle plug, wherein a groove is formed in the top of the left carbon body, a groove is formed in the top of the right carbon body, a vertical through hole is formed inside the left carbon body, a vertical through hole is formed inside the right carbon body, one end of the right carbon brush wire is connected with the upper end of the right carbon body, one end of the left carbon brush wire is connected with the upper end of the left carbon body, and the other end of the left carbon brush wire and the other end of the right carbon brush wire are enwound together to be fixed in one end of the angle plug.
Description
Technical field
The present invention relates to a kind of carbon brush, in particular for the porose carbon brush of automobile start motor.
Background technology
Carbon brush is the device of transferring energy or signal between the standing part of motor or generator or other rotating machineries and rotating part, in the time of electric machine rotation, electric energy is flowed to coil by phase changer.Carbon brush, as a kind of sliding contact part, is widely used in many electric equipments.Traditional carbon brush is generally that pure carbon adds coagulating agent and makes, and external form is generally square, and volume varies, and on top, has wire to draw.The automobile starter carbon brush is the sliding contact part of conduction current on the starter commutator, very easily wearing and tearing.In addition, existing automobile starter carbon brush and commutator, slip ring between the high speed relative rotary motion in, produce frictional noise and frictional heat, reduce the useful life of carbon brush.。
Summary of the invention
The objective of the invention is for solving existing issue above-mentioned.
For addressing the above problem, technical scheme of the present invention is: the porose carbon brush of a kind of automobile start motor, by left carbon body, right carbon body, left brush lead, right brush lead, the angle insert group becomes, a groove is arranged at the top of left carbon body, a groove is arranged at the top of right carbon body, a top-down through hole is arranged in left carbon body, a top-down through hole is arranged in right carbon body, one end of right brush lead is connected with right carbon body upper end, one end of left brush lead is connected with left carbon body upper end, the other end of left brush lead and the other end of right brush lead are intertwined, jointly be fixed in an end of inserting at angle.
As a further improvement on the present invention, the groove at left carbon body and right carbon body top is " U " type groove.
As a further improvement on the present invention, brush lead is the copper braided wire, transferring energy that not only can be good and signal but also can reduce manufacturing cost.
To sum up, the present invention can guarantee the commutation stability of motor, extends the useful life of carbon brush, increases economic efficiency.In addition, this carbon brush inside has through hole, can the distributed noise direction of propagation, thus play the effect of noise reduction; The heat of brush inside can be taken away internal heat by the air-flow of the through hole of flowing through, and effectively plays the effect of heat radiation, has social benefit preferably.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, this automobile start motor is inserted 5 with porose carbon brush by left carbon body 1, right carbon body 2, left brush lead 4, right brush lead 3, angle and is formed, a groove 7 is arranged at the top of left carbon body 1, a groove 6 is arranged at the top of right carbon body 2, a top-down through hole 8 is arranged in left carbon body 1, a top-down through hole 9 is arranged in right carbon body 2, and the cross-sectional area of through hole is 1.0-2.0mm
2, an end of right brush lead 3 is connected with right carbon body 2 upper ends, and an end of left brush lead 4 is connected with left carbon body 1 upper end, and it is characterized in that: the other end of the other end of left brush lead 4 and right brush lead 3 is intertwined, and jointly is fixed in an end at angle slotting 5.In addition, brush lead 3 is the copper braided wire, has good electric conductivity.
