Abstract
The utility model provides a brush traction motor built-in cooling device, which is positioned on the rear portion of motor; a oriented cooling fan is adopted and disposed between the motor rear bearing and the commutator; the brush-holder is disposed between the brush-holder fixing plate and the fan; the brush-holder fixing plate is mounted on the right end inner wall of the rear cover. When the motor runs, the cooling wind generated by the fan passes through the ventilating opening outside the brush-holder, the brush-holder and the commutator, and is discharged through the ventilating opening. The device can effectively perform direct cooling to the commutator which is easily to be heated to high temperature; and discharge the harmful carbon generated by electrical spark and friction in the working process of commutator; thereby, increases motor efficiency, reduces motor temperature rise, prolongs motor service life, and improves motor safety reliability greatly.
Description
Technical field
Cooling device, especially electric vehicle that the utility model includes the brush traction electric machine have the cooling device of brushing the middle low power traction electric machine.
Background technology
Have the type of cooling of brush traction electric machine to be divided into natural air cooled (no cooling fan) in the market, rearmounted outer cooling fan (fan is at the afterbody shaft extension position of rear bearing) though these types of cooling are convenient to design, are installed, is unfavorable for heat radiation; In addition since the electric spark that the commutator of traction electric machine produces when commutation with and harmful dust of producing remain in motor internal, make the user of motor regularly clear up maintenance, otherwise will damage motor the commutator of motor.
Summary of the invention
In order to overcome the existing problem that has the harmful dust that produces in brush traction electric machine weak heat-dissipating, the operation process to retain motor internal, the utility model provides a kind of electric machine built-in cooling device, the position that this device directly easily produces high temperature to motor: commutator cools off, simultaneously the electric spark that commutator is produced when the commutation with and harmful dust of producing discharge.Reduce the temperature of commutator, improved the anti-wear performance of commutator, prolonged the useful life of motor.
The technical scheme that its technical problem that solves the utility model adopts is, fan directly is placed between the rear bearing and commutator of motor, and brush carrier is placed between brush carrier fixed head and the fan, and the brush carrier fixed head is installed on the right-hand member inwall of bonnet.During motor rotation, discharge by ventilating opening through brush carrier outside ventilating opening, brush carrier, commutator by the cooling air that fan produces.
The beneficial effects of the utility model are, this device can directly easily produce the position of high temperature to motor: commutator cools off, simultaneously the electric spark that commutator was produced in when commutation with and harmful dust of producing discharge, reach the temperature rise that improves electric efficiency, reduces motor, the purpose that prolongs the useful life of motor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is traditional structural representations that the rearmounted cooling device of brush traction electric machine is arranged.
Among the figure, the 1st, rear bearing, the 2nd, fan, the 3rd, brush carrier, the 4th, brush carrier fixed head, the 5th, commutator, the 6th, bonnet, the 7th, ventilating opening.
Embodiment
In Fig. 1, fan of the present utility model (2) directly is placed between the rear bearing (1) and commutator (5) of motor, brush carrier (3) is placed between brush carrier fixed head (4) and the fan (2), brush carrier fixed head (4) is installed on the inwall of right-hand member of bonnet (6), during motor rotation, discharge by ventilating opening (7) through brush carrier (3) outside ventilating opening, brush carrier (3), commutator (5) by the cooling air that fan (2) produces.The direct position that motor is easily produced high temperature: commutator cools off, simultaneously the electric spark that commutator was produced in when commutation with and harmful dust of producing discharge, reach the temperature rise that improves electric efficiency, reduces motor, the purpose that prolongs the useful life of motor.
In Fig. 2, the fan of this device (2) is to be placed on the back shaft of rear bearing (1) on the market, and brush carrier (3) is the right side that is placed on brush carrier fixed head (4), and brush carrier fixed head (4) is mounted in the bottom of bonnet (6).Though this type of cooling is convenient to design, is installed, and is unfavorable for heat radiation; In addition since the electric spark that commutator produced in when commutation with and harmful dust of producing easily remain in motor internal, be difficult for discharging.
Claims (1)
1. one kind has the built-in cooling device of brush traction electric machine, it is made up of bonnet (6), rear bearing (1), fan (2), brush carrier (3), brush carrier fixed head (4), it is characterized in that: fan (2) directly is placed between the rear bearing (1) and commutator (5) of motor, brush carrier (3) is placed between brush carrier fixed head (4) and the fan (2), and brush carrier fixed head (4) is installed on the right-hand member inwall of bonnet (6).
