Description
Technical field
The present invention relates to a kind of hall effect type steering wheel angle sensor based on single-pinion planetary gear transmission.
Background technology
Steering wheel angle sensor is the main sensors of automobile ESP system, electric suspension system and electric steering system.
In order that driver's steering is light, the drift angle of the corner of steering wheel and deflecting roller is generally arranged to larger gearratio, turned to
The left and right level limit corner of disk is usually 4 circles or so, this just the structure to steering wheel angle sensor and rat tail propose compared with
High requirement.And traditional steering wheel angle sensor is complicated, signal reliability is low, and fault rate is high.
The content of the invention
The defects of the present invention seeks to exist for prior art, provides a kind of Hall based on single-pinion planetary gear transmission
Effect type steering wheel angle sensor.
The present invention to achieve the above object, adopts the following technical scheme that：A kind of Hall based on single-pinion planetary gear transmission
Effect type steering wheel angle sensor, including single-stage planetary gear train, the input of the single-stage planetary gear train is with turning
To axis connection, the output end of the single-stage planetary gear train is connected with signal teeth；The output end of the signal teeth passes through Hall
Component is connected with electronic control unit.
Further, the single-stage planetary gear train includes gear ring, and planet carrier, the planet are provided with the gear ring
Sun gear is provided with frame, planetary gear is provided between the sun gear and the gear ring；Wherein, the sun gear with it is described
Axis connection is turned to, the planet carrier is connected with the signal teeth.
Further, the Hall subassembly includes the first Hall element and the second Hall element, first Hall element
And second Hall element be arranged between the signal teeth.
Beneficial effects of the present invention：Sensor of the invention structure and control principle are simple, and signal reliability is high, fault rate
It is low, slowed down by the single-stage planetary gear train of setting, whole rotational angles of signal teeth can be made to be less than 360 °, such as a row
The gearratio of planetary gears is not big enough, the rows of planetary gear mechanism that can connect again combination transmission.Electronic control unit according to
Hall signal, which carries out computing and processing, just can accurately know the rotation direction and angular dimension of steering wheel.
Brief description of the drawings
Fig. 1 is the transmission principle schematic diagram of the present invention.
Fig. 2 is the control principle schematic diagram of the present invention.
Embodiment
Shown in Fig. 1 and Fig. 2, it is related to a kind of hall effect type steering wheel sensing based on single-pinion planetary gear transmission
Device, including single-stage planetary gear train, the input of the single-stage planetary gear train are connected with steering spindle 1, the single-stage row
The output end of star gear mechanism is connected with signal teeth 6；The output end of the signal teeth 6 passes through Hall subassembly and electronic control unit
Connection.
Wherein, the single-stage planetary gear train includes gear ring 4, and planet carrier 5, the planet are provided with the gear ring 4
Sun gear 2 is provided with frame 5, planetary gear 3 is provided between the sun gear 2 and the gear ring 4；Wherein, the sun gear 2
It is connected with the steering spindle 1, the planet carrier 5 is connected with the signal teeth 6.
Wherein, the Hall subassembly includes the first Hall element 71 and the second Hall element 72, first Hall element
71 and second Hall element 72 be arranged between the signal teeth 6.
The transmission principle of the present invention is as shown in figure 1, the gear ring 4 of single-stage planetary gear train is fixed, planet carrier 5 and signal teeth
6 are connected, and are designed by the suitable number of teeth, and single-stage planetary gear train diminishes the corner of steering wheel output on request, makes planet
Its corner when steering wheel or so level is limited and rotated is less than 360 ° to frame 5 with signal teeth 6.
Control principle as shown in Fig. 2 signal teeth one of tooth for special shape (according to the shape size of Hall element
Set), the first Hall element and the second Hall element close to signal teeth correct position, it is special when deflecting roller forward direction is facing forward
Shape tooth is exactly in the centre position between the first Hall element and the second Hall element, and when steering wheel turns to, first suddenly
Hall signal caused by that element and the second Hall element is conveyed to electronic control unit, and electronic control unit is according to hall signal
Carrying out computing and processing just can accurately know the rotation direction and angular dimension of steering wheel.
The present invention is slowed down by the single-stage planetary gear train of setting, and whole rotational angles of signal teeth 6 can be made small
In 360 °, the gearratio of a such as rows of planetary gear mechanism is not big enough, the rows of planetary gear mechanism that can connect again combination transmission.Electronics
Control unit carries out computing and processing according to hall signal just can accurately know the rotation direction and angular dimension of steering wheel.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
