Abstract
The utility model discloses a plane commutator of an automobile motor, which comprises a mould body and a commutator segment, wherein the upper end face of the commutator segment forms the working face of the plane commutator. The plane commutator is characterized in that a dove-tail slot is formed on the lower end face of the commutator segment, which is connected with the mould body, and a hook-shaped slot is formed on the inner end face of the commutator segment; and a reinforcement ring is arranged in the plane commutator, and penetrates the hook-shaped slot on the commutator segment. The plane commutator disclosed by the utility model is strong in radial pulling force resistance under a condition of high-speed rotation, has high safety and reliability, and is long in service life.
Description
[technical field]
The utility model relates to a kind of commutator, is specifically related to a kind of electric motor of automobile flat commutator.
[background technology]
At present, the user is bigger to used electric motor of automobile serviceability reflection, mainly is that the anti-radial pull ability of electric motor of automobile flat commutator is relatively poor; Useful life is shorter; Trace it to its cause and be: 1. commutator does not have the steel loop reinforcing, and tensile strength is relatively poor, at present; The steel loop reinforcement technique only is applied to radially commutator, but on flat commutator, adopts difficulty very big; 2. the trench structure of commutator segment is unreasonable, and die body breaks away from commutator segment after being shaped and solidifying easily.
[summary of the invention]
In view of the deficiency of prior art, the technical problem that the utility model will solve is to be to provide a kind of anti-radial pull ability strong electric motor of automobile flat commutator.
The utility model takes following technical scheme to accomplish: the electric motor of automobile flat commutator; Comprise die body and commutator segment; The upper surface of commutator segment forms the working face of flat commutator together; It is characterized in that: the lower surface that commutator segment connects with die body is provided with dovetail groove, and inner face is provided with the hook groove.Be provided with reinforcing ring in the electric motor of automobile flat commutator, reinforcing ring is located in the dovetail groove of commutator segment.
The electric motor of automobile flat commutator of said structure; At first adopted novel composite type trench structure; The die body material can fully be fused in dovetail groove and the groove of commutator segment solidify, effectively improve the ability of the anti-radial pull of commutator product, improve the security reliability that product uses; Secondly, in commutator, adopt the reinforcing ring reinforcement technique, effectively improve the anti-radial pull ability of commutator product under the high speed rotating situation, prolong more than product 2-3 in useful life times.
[description of drawings]
Fig. 1 is the structure chart of the utility model;
Fig. 2 is the structure chart of commutator segment among Fig. 1.
[embodiment]
As shown in the figure, this electric motor of automobile flat commutator comprises die body 2, commutator segment 1 and reinforcing ring 3; The upper surface 4 of commutator segment forms the working face of flat commutator together; The lower surface that commutator segment 1 connects with die body 2 is provided with dovetail groove 5, and inner face is provided with hook groove 6, this composite type trench structure; Make the die body material can fully be fused to the dovetail groove and the interior curing of groove of commutator segment, said reinforcing ring 3 is located in the dovetail groove 5 of commutator segment.The electric motor of automobile flat commutator of said structure, the anti-radial pull ability under the high speed rotating situation is strong, and security reliability is high, long service life.
