<p>Title: A CARBON BRUSH STRUCTURE Abstract The invention relates to a carbon brush structure, belonging to the technical field of motor manufacture. The carbon brush structure comprises a carbon brush positioning plate, and the center of the carbon brush positioning plate is provided with a central hole for penetration of a commutator. The carbon brush structure is characterized in that two carbon brushes which are centrosymmetric around the central hole are disposed on the carbon brush positioning plate, both carbon brushes are L shape, one end of each L-shaped carbon brush is pivoted with the carbon brush positioning plate, a torsion spring is arranged on each pivot, and one end of the torsion spring acts on the carbon brush such that the free end of the carbon brush tends to press the central hole. The carbon brush structure has simple structure, greater length and longer service life, and can ensure tight contact between the carbon brush and the commutator, solving the problems that the traditional carbon brush has limited length, fast abrasion in use, short service life, complex structure, etc.</p> |
