Abstract
The present invention relates to a changeable carbon brush box for disc motors, which belongs to the field of the structural part design of electromechanical products. The present invention discloses a changeable carbon brush box for disc motors, which comprises a carbon brush box body which is detachably arranged in a narrow shell of a disc motor, two copper sleeves which are arranged on the front end of the carbon brush box body with set angles, two carbon brushes respectively arranged in the two copper sleeves, and a bracing spring arranged on the rear end of the carbon brush box body, wherein two rotary arms of the bracing spring are respectively provided with a small ring sheathed on a leading wire at each tail part of the carbon brushes, and the bracing spring is restricted by the leading wires; the end of one rotary arm of the bracing spring supports at the bottom of the carbon brushes, and the end of the other rotary arm supports on the carbon brush box body. The shell of the changeable carbon brush box for disc motors can also be covered by a carbon brush box cover to form a flat thin whole to be fixedly arranged in a motor shell. When the carbon brushes need replacing, the brush box can be conveniently and integrally taken out from or put in the motor shell without disconnecting the motor, and the carbon brushes can be conveniently assembled and replaced.
Description
Technical field
The present invention relates to a kind of disc type electric machine carbon brush fixing device for installing, be applicable to the disc type electric machine of various electric motor cars, belong to electronic product structural member design field.
Background technology
Domestic electric vehicle motor drive unit comprises two kinds of brush motor and brushless electric machines at present, in brush motor, must have carbon brush and commutator to contact, to realize the input and the commutation of electric current.The disc type electric machine of existing various electric motor cars, its body is flat thin type.Carbon brush holder is a fan-shaped insulation board, is fixed on the motor case when motor assembles, and can not take out or put into from the motor outside, therefore is not easy to check or change carbon brush.The employed spring of carbon brush mainly is a helical compression spring, is installed on the carbon brush holder, all can not change from the outside.Fig. 1 has shown the mounting means of carbon brush and carbon brush holder in the prior art, and wherein two copper sheathings 3 are arranged and are fixed on the carbon brush holder 1 by certain angle, and two carbon brush 4 are placed in the copper sheathing, and be pressed on the commutator 5 with stage clip 2.
Summary of the invention
Existing disc type electric machine can't not taken motor apart and change brush-box and carbon brush thereof from the outside, because disc type electric machine is flat structure, axial dimension is very little, if do not strengthen axial dimension, be difficult to that motor is not taken in realization apart and take out brush-box from the outside and change its carbon brush from narrow space, although a lot of people want to solve this technical barrier, do not see both at home and abroad that so far the someone realizes.
In order to address the above problem, the invention provides a kind of changable type carbon brush case for disc electric motor, it is characterized in that: described changable type carbon brush case for disc electric motor comprises the brush-box box body that is removably mounted in the narrow housing of disc type electric machine, is placed on two copper sheathings of described brush-box box body front end, is installed in two carbon brush in described two copper sheathings and the support spring that is located at described brush-box box body rear end respectively with set angle; Two pivoted arm ends of described support spring are equipped with little ring, and described cyclotella sleeve makes support spring be retrained by described lead-in wire on the lead-in wire of described carbon brush afterbody; The end portion supports of a pivoted arm of described support spring is in the carbon brush bottom, and the end portion supports of another pivoted arm is on the brush-box box body.
In the present invention, described brush-box box body can be pancake.
In the present invention, described interchangeable brush-box also comprises the carbon brush lid that is used to cover described support spring and copper sheathing, described carbon brush lid and carbon brush box body removably snap together, form flat thin integral body, be installed in the narrow housing of disc type electric machine, can take motor apart, from the motor outside brush-box be taken out easily or pack into.
Beneficial effect of the present invention is:
1) the brush-box box body is removably mounted in the electric machine casing of flat narrow, and it can be taken out easily or put into, to change carbon brush;
2) two carbon brush are installed in the same brush-box box body, the angle between can two carbon brush of strict guarantee, thus guarantee that when carbon brush is put in the outside angle strictness between two carbon brush is constant;
3) carbon brush is placed in the copper sheathing, guarantees that carbon brush is movable smoothly, and unlikely again have excessive becoming flexible, thereby guarantee that carbon brush can contact with commutator face in the wear process from growing to lacking all the time reliably closely;
4) support spring pivoted arm end is provided with little ring, on carbon brush lead-in wire, utilizes the carbon brush lead-in wire to connect and the constraint support spring cyclotella sleeve, can realize effectively that support spring to the stable support of carbon brush with exert pressure, is unlikely to the situation that slippage occurs or block;
5) the brush-box box body adopts flat pattern, with the space of the flat narrow of utilizing the disc type electric machine housing fully, makes things convenient for the taking-up of brush-box or puts into.

Embodiment
Further specify the present invention below in conjunction with drawings and Examples.
In an exemplary embodiments of the present invention, as shown in Figure 2, changable type carbon brush case for disc electric motor comprises brush-box box body 1, be placed on set angle (as 45 ° or 60 °) as described in the brush-box box body two copper sheathings 3, respectively be movably arranged on as described in two carbon brush 4 in two copper sheathings, and the support spring 2 that is located at described brush-box box body bottom.Described brush-box box body is pancake in the present embodiment, and the cross sectional shape of brush-box box body is trapezoidal in the present embodiment.Described brush-box box body is detachably mounted in the narrow housing (see figure 5) of disc type electric machine, in the present embodiment, utilizes screw-driving on the narrow housing of disc type electric machine.
The end portion supports of a pivoted arm of support spring 2 is in carbon brush bottom, the end portion supports of another pivoted arm on the brush-box box body, thereby carbon brush is pressed on the commutator 5.Support spring 2 can be made by steel wire.Two pivoted arm ends of support spring 2 are equipped with little ring (seeing Fig. 4 for details), and described cyclotella sleeve utilizes the carbon brush lead-in wire to connect and the constraint support spring on the lead-in wire of described carbon brush 4 afterbodys, makes support spring withstand carbon brush reliably, and guarantees that carbon brush freely compresses and stretches.This structure has reached the purpose of reliable connection and constraint, is the new bind mode that did not all have both at home and abroad.
