Example Embodiment

[0019] The present invention will be further described below with reference to the drawings and embodiments.

[0020] In a typical embodiment of the present invention, such as figure 2 As shown, the disc motor replaceable carbon brush box includes a carbon brush box body 1, two copper sleeves 3 placed in the carbon brush box body at a set angle (such as 45° or 60°), respectively Two carbon brushes 4 movably installed in the two copper sleeves, and a brace spring 2 arranged at the lower part of the carbon brush box box body. The carbon brush box box body is flat in this embodiment, and the cross-sectional shape of the carbon brush box box body is trapezoidal in this embodiment. The carbon brush box body is detachably installed in the narrow shell of the disc motor (see Figure 5 ), in this embodiment, screws are used to tighten the narrow shell of the disc motor.

[0021] The end of one rotating arm of the support spring 2 is supported on the bottom of the carbon brush, and the end...

Abstract

This invention discloses a changeable carbon brush box of a disk motor including a dismountable box mounted on the narrow shell of the disk motor, two copper jackets set at the front of the box in a certain angle, two carbon brushes in the copper jackets and a bracing spring set at the back of the box, in which, small rings are set at the ends of the two rotation arms of the spring and jacket the leads at the tails of the brushes to restrict the bracing spring, the end of one rotation arm of which supports the bottom of the brush, the end of the other supports the box and the carbon brush box shell can be covered by the cover of the box to become a flat integer mounted in the motor shell fixedly.

Description

technical field [0001] The invention relates to a mounting and fixing device for a carbon brush of a disc motor, which is suitable for disc motors of various electric vehicles and belongs to the field of mechanical and electrical product structural part design. Background technique [0002] At present, domestic electric vehicle motor drive devices include brushed motors and brushless motors. In brushed motors, carbon brushes must be in contact with the commutator to realize current input and commutation. The disc motors of existing various electric vehicles have a flat and thin body. The carbon brush holder is a fan-shaped insulating plate, which is fixed on the motor casing when the motor is assembled, and cannot be taken out or put in from the outside of the motor, so it is not convenient to check or replace the carbon brush. The springs used in carbon brushes are mainly helical compression springs, which are installed on the carbon brush holder and cannot be replaced fro...
