The problem of production. art is bad, has and realizes that assistant sensor assembling is simple and convenient, uniformity is strong, significantly improve power-assisted biography
The advantageous effects of the production efficiency of sensor.
The technical problem that the utility model is solved is realized using following technical scheme：A kind of middle shaft structure, including in
Axis, described axis one end are axially limited by being interference fitted axial assembling and radially defined magnet ring and bearing, one side of magnet ring
Due to the magnet ring positioning shaft shoulder on axis, another side of magnet ring is axial mutually to limit the one end for being connected to bearing, the magnetic
Another side end face annular of ring forms groove, and the groove is by being interference fitted embedded magnet steel.
Further, the magnet ring and bearing are axial mutually limits connection positioning, and realizes magnet ring with being pressed while bearing
Position is attached to, is servo-actuated in axis.
Further, another side end face annular of the magnet ring forms multiple grooves, and each groove is embedded in corresponding magnet steel.
Further, the magnet steel on the magnet ring surface forms rotating excitation field with central axis.
Advantageous effects：
1st, this patent uses described axis one end by being interference fitted axial assembling and radially defined magnet ring and bearing, described
One side of magnet ring is axially confined is connected to axis in the magnet ring positioning shaft shoulder on axis, axial mutually limit in another side of magnet ring
The one end held, another side end face annular of the magnet ring form groove, the groove by being interference fitted embedded magnet steel, due to including
Axis, magnet ring.On the axis, equipped with magnet ring bearing one end, using identical special of the diameter of axle in assembled portion length
Structure, it is possible to achieve magnet ring makes bearing inner race realize bearing by the shaft shoulder and by magnet ring with being press-fit into place while bearing
Axially position, while also achieve the axially position of magnet ring；Interference fit is belonged between bearing and magnet ring and axis, it is real
The radial direction and rotational positioning of bearing and magnet ring are showed, bearing is realized with magnet ring and rotated with together with axis.In the magnetic
Multiple grooves for being used to be embedded in magnet steel are provided with ring end face, is interference fitted between magnet ring and groove, magnet steel is fixed in groove,
One is formed with magnet ring to rotate with axis, and then forms required changing magnetic field, due to the difference eventually through magnetic field
Change to detect the situation of vehicle operation, suitable for the application of vehicle using motor.
2nd, this patent is axially confined another in the magnet ring positioning shaft shoulder on axis, the magnet ring using one side of magnet ring
One side is axial mutually to limit the one end for being connected to bearing, since equipped with magnet ring bearing one end, assembled portion length is interior to be used
The identical special construction of the diameter of axle, it is possible to achieve magnet ring makes bearing inner race by the shaft shoulder and pass through with being press-fit into place while bearing
Magnet ring realizes the axially position of bearing, while also achieves the axially position of magnet ring；All belong between bearing and magnet ring and axis
In interference fit, the radial direction and rotational positioning of bearing and magnet ring are realized, bearing is realized with magnet ring and turns with together with axis
It is dynamic, therefore, the structure of magnet ring and the installation of axis integral type is simplified, is pressed into magnet ring together when being pressed into bearing, Er Qie
It is also easier in terms of manufacture and assembling.
3rd, this patent is servo-actuated in axis using the magnet ring and bearing, since magnet ring and bearing are servo-actuated in axis, carry
The high follow-up characteristic of device.
4th, this patent production efficiency is high, and production cost can be greatly lowered；More reliable performance is stablized.
