Description
Technical field
The utility model relates to vehicle technology field, is specifically related to a kind of for the speed changer of electric motor car and the integral component of motor.
Background technology
Electric motor car is using electricity as driving power, and automobile touch oil provides power.Basic demand for electric vehicle motor performance is: enough large starting torque, the requirement starting, accelerate, climb, frequently open, stop fast; The speed adjustable range of motor is little; Specific power large (specific power is defined as the maximum power that unit mass can provide), with maximum power timing; Torque response characteristic fast, mildly can control fast to drive and brake torque in various vehicle speed range, require that motor controllability is high, stable state accuracy and dynamic characteristic good; There is good environmental suitability, can reliably work under different operating conditions; Safeguard simple, work noise is low.Basic demand for decelerator performance is: reasonable in design, and assembly transmission efficiency is high, runs sound little, and the response time is fast, can reliability service under different transmission rotating speeds.
Existing motor is arranged on outside speed changer, and the motor shaft of motor and the power input shaft of speed changer are arranged separately, and motor shaft drives the power input shaft of speed changer to rotate by spline, shaft coupling, easily causes and connects abnormal sound or Problem of Failure.In addition, the power input shaft of motor shaft, speed changer needs outfit two bearings respectively, adds manufacturing cost, increases overall dimensions.
Utility model content
The purpose of this utility model is to provide a kind of speed changer and the 18KW motor integral assembly that are exclusively used in electric motor car, avoids connecting abnormal sound or Problem of Failure, reduces manufacturing cost, reduces overall dimensions.
In order to achieve the above object, a kind of speed changer and 18KW motor integral assembly being exclusively used in electric motor car that the utility model provides, comprise the permanent magnet reluctance motor of speed changer and 18KW, the shell of described speed changer is locked together by bolt and nut by after case lid and casing fastening, it is characterized in that: determining of described permanent magnet reluctance motor, rotor all adopts silicon steel plate packing to form, and on rotor, be embedded with circumferentially uniform magnet steel, the motor shaft of permanent magnet reluctance motor and the power input shaft of speed changer share same axis, the diameter of axle of this common axis is 40 ~ 50mm, wherein one end of common axis is arranged in permanent magnet reluctance motor by bearing, the other end is arranged in speed changer by bearing, the middle part of common axis is arranged on the cohesive position place of permanent magnet reluctance motor and speed changer by bearing.
Be preferably, described permanent magnet reluctance motor is positioned at the outer side near case lid of speed changer, and the clutch end of speed changer is positioned at the side near casing.The clutch end of permanent magnet reluctance motor and speed changer staggers and arranges, and is convenient to Appropriate application space structure and carries out mounting arrangements.
The beneficial effects of the utility model:
(1) drive motors adopts permanent magnet reluctance motor, the stator and rotor of this motor all adopt silicon steel plate packing to form, and on rotor, be embedded with circumferentially uniform magnet steel, specific power large (specific power is defined as the maximum power that unit mass can provide), with maximum power timing, (1 ~ 1.25) more than kw/kg generally should be reached; Torque response characteristic fast, can mildly control fast in various vehicle speed range drive and brake torque, motor controllability is high, stable state accuracy and dynamic characteristic good; There is good environmental suitability, can reliably work under different operating conditions; Safeguard simple, work noise is low; This motor has enough large starting torque, applies it in electric motor car, is satisfied with the requirement of quick startup, acceleration, climbing, frequent start-stop.
(2) motor shaft of permanent magnet reluctance motor and the power input shaft Integral design of speed changer, the connection abnormal sound adopting splined to bring after effectively evading split design and inefficacy; Save a bearing, reduce manufacturing cost, and reduce overall dimensions, make overall structure more compact; And the diameter of axle matching relationship of axle is used together by controlling permanent-magnet reluctance electrical acc power, Assurance component service behaviour is optimum;
(3) for electric motor car, the diameter matches relation of drive motors power and transmission power power shaft is extremely important, directly have influence on the performance of electric motor car, the utility model adopts the version of the motor shaft of permanent magnet reluctance motor and the power input shaft Integral design of speed changer first in electric motor car, the basis of traditional structure there occurs subversive change, its permanent-magnet reluctance electrical acc power just needs to redefine with the diameter of axle matching relationship of axle together, if the diameter of axle crosses conference increase manufacturing cost, product weight and overall dimension, the diameter of axle too small useful life reducing again product, permanent-magnet reluctance electrical acc power uses the diameter of axle matching relationship of axle most important together.
