Abstract
The present utility model discloses an electric automobile driving motor rotary transformer positioning mechanism. The mechanism is characterized in that a bearing gland is arranged on a motor rotor, and a motor bearing is fixed on a bearing pedestal of a rear end cover of a motor through the bearing gland and gland screws. Through accurate axial positioning of a rotor and a stator of a rotary transformer, accurate detection of a position signal can be guaranteed.
Description
Technical field
The utility model relates to a kind of detent mechanism of driving motor for electric automobile resolver, is used for guaranteeing the axial location of resolver.
Background technology
Along with the Global Auto recoverable amount further strengthens, the problems such as energy crisis, environmental pollution and global warming become increasingly conspicuous, and new-energy automobile, especially electric automobile become the emphasis of domestic and international motor corporation development.No matter from environmental angle or energy angle, following electric motor car all needs to have a large development, and its exploitation will be related to the ups and downs of numerous industry, may become following new growth engines.In China, electric automobile more has unique market, and metropolis all ubiquity very serious traffic problems and motor vehicle exhaust emission pollution problem.As the daily vehicles of a kind of small-sized, middling speed and short distance, electric motor car is very good, and it has advantageous development condition and wide application prospect in China.
drive motors has its unique distinction as the kernel component of electric automobile, comparing it with the traditional industry motor requires more reliable, because it directly has influence on normally travelling and personal safety of automobile, resolver is Split type structure as the rotor-position sensor of drive motors due to its rotor and stator, that rotor with resolver is fixedly connected with the rotor of drive motors in installation process, stator with resolver is fixedly connected with the stator of drive motors, and have axial endplay between the rotor of drive motors and stator, therefore can cause the position detection signal distortion of resolver.
The utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of driving motor for electric automobile resolver detent mechanism is provided, carry out axial location accurately by rotor and stator to resolver, guarantee the accurate detection of its position signalling.
The utility model is that the technical solution problem adopts following technical scheme:
A kind of driving motor for electric automobile resolver detent mechanism, its design feature is: a bearing gland is set on rotor, by described bearing gland and gland screw, motor bearings is fixed in the bearing pedestal of back end cover for motor.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, because resolver rotor and stator are Split type structure, that rotor with resolver is fixedly connected with the rotor of drive motors in installation process, stator with resolver is fixedly connected with the stator of drive motors, and have axial endplay between the rotor of drive motors and stator, therefore can cause the position detection signal distortion of resolver, the utility model increases on rotor a bearing gland is set, by bearing gland and gland screw, the drive motors rotor is axially being made the location, thereby effectively eliminated the axial motion of electric machine rotor, guaranteed the normal output of signals of rotating transformer,
2, the utility model has overcome the unmanageable problem of installation resolver axial displacement, has simplified the installation of resolver rotor;
3, the utility model positions electric machine rotor by bearing gland and has reduced the motor in electric automobile rotor vehicle transmission is partly brought additional impact, has effectively protected the stability of drive system;
4, the utility model is fixed the drive motors rear bearing by bearing gland, has reduced the axial impact of bearing, has effectively guaranteed the useful life of bearing.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model decomposition texture schematic diagram;
Number in the figure: 1 bearing gland; 2 armature spindles; 3 motor bearingss; 4 back end cover for motor; 5 gland screws; 6 revolve the sub-pressing plate hold-down screw of set; 7 revolve set; 8 revolve change rotor press plate, 9 revolves change rotor press plate hold-down screw; 10 revolve change rotor, 11 revolves the sub-pressing plate of set.
Embodiment
Referring to Fig. 1, Fig. 2, in the present embodiment, driving motor for electric automobile resolver detent mechanism is that a bearing gland 1 is set on rotor 2, by bearing gland 1 and gland screw 5, motor bearings 3 is fixed in the bearing pedestal of back end cover for motor 4.
In concrete enforcement, before press-fiting motor bearings 3, bearing gland 1 is sleeved on armature spindle 2, motor bearings 3 is colded pressing to the armature spindle 2 of drive motors again, revolve change rotor 10 and become by revolving to become rotor press plate 8 and revolve the tail end that rotor press plate hold-down screw 9 is fixed on armature spindle 2, revolve like this change rotor 10 and just be arranged on rotor; Revolving set 7 is fixed on drive motors stator rear end cap 4 by revolving the sub-pressing plate 11 of set and revolving the sub-pressing plate hold-down screw 6 of set, become rotor 10 and just begin both assembling after being arranged on respectively on back end cover for motor 4 and armature spindle 2 with revolving revolving set 7, mode by hot jacket is enclosed within back end cover for motor 4 on motor bearings 3, by bearing gland 1 and bearing gland hold-down screw 5, rotor and back end cover for motor 4 are bound together again, complete whole installation process.
In assembling process, the axial dimension of rotor axis of electric 1 and rear end cap 4 controlled well just can be well becomes rotor 10 and carry out axial location revolving set 7 and revolving.
resolver is as high-precision position transducer, excitation voltage is 7V(AC), output cosine and sine signal voltage is also lower, if this time, axially the larger words output signal of alignment error will weaken, will affect the normal reception of signal, so revolve to become and require to revolve set rotor axial error in installation process between ± 0.25mm, in the present embodiment, as shown in Figure 2, L1=L2 is optimum state in assembling in theory, but in fact parts have error in the course of processing, so only control the size of L2 in L1 in armature spindle 2 and back end cover for motor 4 well, the value that makes L1-L2 could satisfy instructions for use between ± 0.25mm.
L1 refers to that the outside, armature spindle upper bearing (metal) location becomes the inboard distance in rotor location to revolving, and L2 refers to that rear end cap upper bearing (metal) locating surface is to revolving the inboard distance in set location.
