Embodiment Construction

[0039] Such as Figure 1-Figure 3 As shown, the carbon brush holder assembly includes a brush holder box 1, a positive electrode base plate 2 and a negative electrode base plate 3, a positive electrode carbon brush 9 and a negative electrode carbon brush 8 and a spring 7 that drives them to move, an insulating sheath 5, a positive electrode connecting wire 6 and Carbon brush temporary fixing ring 4. The brush holder box 1, the positive base plate 2 and the negative base plate 3 are correspondingly provided with coaxial hollow holes for the starter shaft to pass through. Before assembly, the carbon brush temporary fixing ring 4 is installed in the coaxial hollow holes. There are three positive electrode carbon brushes 9 and three negative electrode carbon brushes 8 , which are respectively welded on the positive and negative electrode base plates 2 and 3 .

[0040] Such as Figure 4-Figure 6 As shown, the brush holder box 1 is one-time injection molding, and it is provided wi...

Abstract

The invention provides a carbon brush holder assembly for a starter, which comprises a brush holder box, a positive pole baseplate and a negative pole baseplate which are arranged on the brush holder box, positive pole carbon brushes, negative pole carbon brushes, springs for driving the positive pole carbon brushes and the negative pole carbon brushes to move, an insulating sheath, a positive pole connecting wire and a carbon brush temporary fixing ring, wherein the brush holder box, the positive pole baseplate and the negative pole baseplate are correspondingly provided with a coaxial hollow hole for a starter rotary shaft to pass through. The assembly is characterized in that three positive pole carbon brushes and three negative pole carbon brushes are respectively welded on the positive pole baseplate and the negative pole baseplate, the brush holder box is formed by one-time injection molding and is provided with three positive pole brush holder grooves and three negative pole brush holder grooves respectively corresponding to the negative pole carbon brushes and the negative pole carbon brushes, the positive pole baseplate and the negative pole baseplate are provided with square grooves which respectively corresponds to the positive pole brush holder grooves and the negative pole brush holder grooves and are used for assembling the springs. A six-brush assembling structure can increase the working performance and prolong the service life. The assembly has a simple assembling process and convenience in assembling, thus improving the assembling efficiency obviously.

Description

technical field [0001] The invention relates to a carbon brush holder assembly for a starter and an assembly method thereof, and is especially suitable for a starter for a start-stop system with high requirements on service life. Background technique [0002] The carbon brush holder of the traditional starter is a four-carbon brush structure, that is, two positive carbon brushes and two negative carbon brushes. Fast, poor durability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a carbon brush holder assembly for a starter with six carbon brushes and its assembly method, which overcomes the large current fluctuations during the operation of the motor in the existing four-carbon brush structure and the The disadvantage of large sparks between the carbon brush and the commutator improves the durability of the product. [0004] Technical scheme of the present invention is: [0005] The carbon brush holder assem...
