Description
Technical field
The utility model 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 that transmits energy or signal between standing part and the rotating part of motor or generator or other rotating machineries, when motor rotates, electric energy is flowed to coil through phase changer.Carbon brush is widely used in many electric equipments as a kind of sliding contact part.Traditional carbon brush generally is that pure carbon adds coagulating agent and processes, and external form generally is a square, and volume varies, and has lead to draw on the top.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 purpose of the utility model is to solving existing issue above-mentioned.
For addressing the above problem, the technical scheme of the utility model is: a kind of automobile start motor is used porose carbon brush, is become by left carbon body, right carbon body, left brush lead, right brush lead, angle insert group; A groove is arranged at the top of left side carbon body; A groove is arranged at the top of right carbon body, and a top-down through hole is arranged in the left carbon body, and a top-down through hole is arranged in the right carbon body; One end of right brush lead is connected with right carbon body upper end; One end of left side brush lead is connected with left carbon body upper end, and the other end of left brush lead and the other end of right brush lead are intertwined, and are fixed on jointly in the end of inserting at the angle.
As the further improvement of the utility model, the groove at left carbon body and right carbon body top is " U " type groove.
As the further improvement of the utility model, brush lead is the copper braided wire, transmission energy that not only can be good and signal but also can reduce manufacturing cost.
To sum up, the utility model can be guaranteed the switching-over stability of motor, prolongs 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 inner heat of brush can effectively play the effect of heat radiation through the carried away by air movement internal heat of the through hole of flowing through, and has the good social benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explanation.
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 side carbon body 1, and a groove 6 is arranged at the top of right carbon body 2, and a top-down through hole 8 is arranged in the left carbon body 1; In the right carbon body 2 a top-down through hole 9 is arranged, 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 is fixed on jointly in the end at angle slotting 5.In addition, brush lead 3 is the copper braided wire, has excellent conducting performance.
