Description
Technical field
The utility model is related to a kind of hall effect type steering wheel angle sensors 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.
It is light in order to turn to driver, the drift angle of the corner of steering wheel and deflecting roller is usually arranged to larger gearratio, is turned to
The left and right grade limit corner of disk is usually 4 circles or so, this just the structure of steering wheel angle sensor and rat tail are proposed compared with
High requirement.And traditional steering wheel angle sensor is complicated, signal reliability is low, high failure rate.
Utility model content
The utility model aim is to provide a kind of to be driven based on single-pinion planetary gear in view of the defects existing in the prior art
Hall effect type steering wheel angle sensor.
The utility model to achieve the above object, adopts the following technical scheme that：It is a kind of based on single-pinion planetary gear transmission
Hall effect type steering wheel angle sensor, including single-stage planetary gear train, the input terminal of the single-stage planetary gear train
With turning to axis connection, the output terminal of the single-stage planetary gear train is connect with signal teeth；The output terminal of the signal teeth passes through
Hall subassembly is connect with electronic control unit.
Further, the single-stage planetary gear train includes gear ring, and planet carrier, the planet are provided in the gear ring
Sun gear is provided in 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 connect 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.
The beneficial effects of the utility model：The sensor structure and control principle of the utility model are simple, signal reliability
Height, failure rate is low, is slowed down by the single-stage planetary gear train of setting, can be less than whole rotational angles of signal teeth
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 processed carries out operation and processing according to hall signal just can accurately know the rotation direction and angular dimension of steering wheel.
Description of the drawings
Fig. 1 is the transmission principle schematic diagram of the utility model.
Fig. 2 is the control principle schematic diagram of the utility model.
Specific embodiment
Shown in Fig. 1 and Fig. 2, it is related to a kind of hall effect type steering wheel sensing being driven based on single-pinion planetary gear
Device, including single-stage planetary gear train, the input terminal of the single-stage planetary gear train is connect with steering shaft 1, the single-stage row
The output terminal of star gear mechanism is connect with signal teeth 6；The output terminal 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 in the gear ring 4
Sun gear 2 is provided in frame 5, planetary gear 3 is provided between the sun gear 2 and the gear ring 4；Wherein, the sun gear 2
It is connect with the steering shaft 1, the planet carrier 5 is connect 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 utility model is as shown in Figure 1, the gear ring 4 of single-stage planetary gear train is fixed, and planet carrier 5 is with believing
Number tooth 6 is connected, and is designed by the suitable number of teeth, and single-stage planetary gear train becomes smaller the corner of steering wheel output as required, makes
Its corner when steering wheel or so grade is limited and rotated is less than 360 ° to planet carrier 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
Setting), the first Hall element and the second Hall element close to signal teeth suitable 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
The hall signal that your element and the second Hall element generate is conveyed to electronic control unit, and electronic control unit is according to hall signal
Carrying out operation and processing just can accurately know the rotation direction and angular dimension of steering wheel.
The utility model is slowed down by the single-stage planetary gear train of setting, can make whole angles of rotation of signal teeth 6
Degree is less than 360 °, and 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.
Electronic control unit carries out operation and processing according to hall signal just can accurately know the rotation direction and angular dimension of steering wheel.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
