In order to achieve the above object, the utility model discloses a following technical scheme realizes: composite carbon brush for automobile starting motor, including the left carbon body, the right carbon body and carbon brush wire, the one end and the left carbon body of carbon brush wire are connected, the other end and the right carbon body of carbon brush wire are connected, the one end that the left side carbon body and the right carbon body are close to electric motor rotor is equipped with the super high lubricating layer of high resistance, the left and right sides of the left side carbon body and the right carbon body are equipped with the copper carbon composite bed respectively, the left side carbon body and the right carbon body include left carbon piece, bond line and right carbon piece respectively, left side carbon piece and right carbon piece pass through the bond line and bond into a whole.
Furthermore, one ends of the left carbon body and the right carbon body, which are close to the motor rotor, are provided with inwards concave arc-shaped grooves.
Further, the adhesive layer is an insulating glue layer.
Further, the carbon brush conducting wire is a copper braided wire.
Furthermore, the connection ends of the carbon brush wire, the left carbon body and the right carbon body are Y-shaped, one bifurcated end of the carbon brush wire is respectively fixed on the left carbon block and the right carbon block of the left carbon body, and the other bifurcated end of the carbon brush wire is respectively fixed on the left carbon block and the right carbon block of the right carbon body.
The utility model has the advantages that: one end of the carbon brush, which is close to the motor rotor, is provided with an inward concave arc-shaped groove, so that the carbon brush can be more attached to the motor rotor, and the carbon brush can be more fully contacted with the motor rotor. The high-resistance ultrahigh lubricating layer and the copper-carbon composite layer can reduce the friction coefficient between the carbon brush and the motor rotor, well inhibit the generation of electric sparks and finally achieve the purposes of reducing the noise of the motor and prolonging the service life of the carbon brush. The forked ends of the carbon brush conducting wires are respectively fixed on the left carbon block and the right carbon block of the left carbon body and the right carbon body, so that the carbon brush can be well fixed, and the load performance and the braking performance of the carbon brush are improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1. the carbon block comprises a left carbon body, a right carbon body, a carbon brush lead, a high-resistance ultrahigh lubricating layer, a copper-carbon composite layer, a left carbon block, a right carbon block and a bonding layer, wherein the left carbon block is 2 carbon bodies, the right carbon block is 3.
Detailed Description
In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.
As shown in fig. 1, the composite carbon brush for the starting motor of the automobile includes a left carbon body 1, a right carbon body 2, and a carbon brush wire 3.
