Abstract
The utility model relates to a traction motor device for a vehicle which comprises a machine seat, a motor and a speed reducing mechanism, wherein, the motor is a disk-shaped permanent magnet DC motor. A disk-shaped armature winding is of wire wound type or printing type, and a permanent magnet is made of ferromagnetic material. The speed reducing mechanism adopts a planetary gear train speed reducing mechanism which is connected with the motor into a whole body by the machine seat. The utility model which adopts the shaft output has the advantages of high efficiency, high safety, strong adaptability, and convenient installation, and is particularly suitable for electro-tricycles, electric flat cars, and forklift trucks. The battery voltage of the utility model is 24 to 48 voltages and the output power of the utility model is 250 to 1200 watts.
Description
The utility model relates to a kind of electric machine, specifically is the automobile-used traction electric machine device of a kind of electric motor car, electric flatbed tricycle etc.
At present, electro-tricycle, electric flatbed tricycle, the traction electric machine of forklift etc. generally adopts the series excitation type motor, because of the operating voltage of above-mentioned vehicle is generally 24～48 volts, power output is between 200～1200 watts, so in use there is following point in the series excitation type motor: owing to adopt series resistance to carry out step-governor d, there is thermal losses in resistance, cause efficient low, softer because of mechanical property, speed governing is passive, causes poor safety performance, when underloading or zero load, it is very fast to travel, and has to slow down by braking brake, when upward slope or heavy duty, speed descends very fast, electric current increases rapidly, and the very easy motor that burns seriously jeopardizes safety traffic.Just because of this, above-mentioned vehicle can't obtain the extensive response in market, and traffic control department also limits the popularization of this type of vehicle.
The purpose of this utility model is at the deficiencies in the prior art, and the automobile-used traction electric machine device with the output of axle form of a kind of efficient height, good speed adjustment features, driving safety is provided.
The utility model is realized with following form:
The utility model comprises support, motor, reducing gear, and wherein motor is the plate-like permanent magnet DC motor, and plate-like armature winding is wire wound or printing formula, and permanent magnet is a strong magnetic material; Reducing gear adopts the planet circular system reducing gear, and motor cabinet connects into an integral body with motor and planet circular system reducing gear.
The star wheel frame and the output shaft of the utility model planet circular system reducing gear are installed on the support, and the output shaft of motor is again the axle of sun gear in the reducing gear.
The utility model is owing to adopt discoid motor, and rotor does not have iron core, does not promptly have iron loss yet, and permanent magnet provides magnetic field, need not exciting current, adopts planet circular system to slow down the efficient height simultaneously; Plate-like magneto mechanical property is hard, cooperates speed setting controller, and speed governing is convenient, driving safety; By support motor and reducing gear are linked to be an integral body, it is horizontal or vertical to adopt base or flange to be mounted to, and applicability is strong; Adopt axle output, simple in structure, easy for installation.
Accompanying drawing is the utility model structural representation.
As shown in the figure, the utility model comprises motor (1), reducing gear (5), support (7), wherein motor (1) is the plate-like permanent magnet DC motor, plate-like armature winding (2) is wire wound or printing formula, permanent magnet (3) is strong magnetic material----neodymium iron boron or ferrite, and reducing gear (5) adopts the planet circular system reducing gear.
The utility model motor (1) is connected with support (7) by connecting bolt, the internal gear of planet circular system reducing gear is installed on the end cap (4) of motor, and star wheel frame (6) and output shaft (8) are installed on the support (7), and the output shaft of motor (10) is again the axle of sun gear (9) in the reducing gear (5).
Claims (3)
1, a kind of automobile-used traction electric machine device, comprise motor (1), reducing gear (5), support (7), it is characterized in that: motor (1) adopts the plate-like permanent magnet DC motor, reducing gear (5) adopts the planet circular system reducing gear, and motor cabinet (7) connects into an integral body with motor and planet circular system reducing gear.
2, according to the described automobile-used traction electric machine device of claim 1, it is characterized in that: motor (1) is connected with support (7) by connecting bolt, the internal gear of planet circular system reducing gear (5) is installed on the end cap (4) of motor, and star wheel frame (6) and output shaft (8) are installed on the support (7), and the output shaft of motor (10) is again the axle of sun gear (9) in the reducing gear (5).
3, according to claim 1 or 2 described automobile-used traction electric machine devices, it is characterized in that: motor permanent magnet (3) adopts strong magnetic material.
