Abstract
The utility model discloses a carbon brush having holes used for an automobile starting motor. The carbon brush having the holes is composed of a left carbon body, a right carbon body and a carbon brush conducting wire; the left carbon body has a top-down through hole, and the right carbon body also has a top-down through hole; and one end of the carbon brush conducting wire is connected to an upper end of a left copper sleeve, and the other end of the carbon brush conducting wire is connected to an upper end of a right copper sleeve. Connecting ends of the carbon brush conducting wire and the carbon brush are Y-shaped structures, which can well fix the carbon brush to avoid swing of the carbon brush; and the through holes can decrease noise and radiate heat, and therefore, the service life of the carbon brush can be prolonged.
Description
Technical field
The utility model relates to a kind of carbon brush, in particular for the porose carbon brush of automobile starting 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 motor commutator, very easily wearing and tearing.Existing automobile starter carbon brush, the link of brush lead and carbon brush are " I " types, be prone to loosening, and can not be well fixing carbon brush, carbon brush is prone to wave and damage.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 starting motor is used porose carbon brush; Form by left carbon body, right carbon body, brush lead, a top-down through hole is arranged in the left carbon body, a top-down through hole is arranged in the right carbon body; One end of brush lead is connected with left carbon body upper end, and the other end is connected with right carbon body upper end.
As the further improvement of the utility model, the link of brush lead and left carbon body and right carbon body is " Y " type.
As the further improvement of the utility model, brush lead is the copper braided wire.
To sum up, the link of the utility model brush lead and left carbon body and right carbon body is " Y " type, and fixing carbon brush has improved the degree of stability of carbon brush, has prolonged the useful life of carbon brush, has improved the load performance and the braking ability of actuating motor.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.
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 starting motor is used porose carbon brush, is made up of left carbon body 1, right carbon body 2, brush lead 3, and a top-down through hole 4 is arranged in the left carbon body 1, and a top-down through hole 5 is arranged in the right carbon body 2, and the cross-sectional area of through hole is 1.0-2.0mm
2One end of brush lead 3 is connected with left carbon body 1 upper end, and the other end is connected with right carbon body 2 upper ends; Brush lead 3 is " Y " type with the link of left carbon body 1 and right carbon body 2, well improves the degree of stability of carbon brush body.In addition, brush lead 3 is the copper braided wire, has excellent conducting performance.
