Abstract
The invention provides a non-contact throttle position sensor which comprises a shell body, a rotor, a rotor shaft, a rotation board and a circuit board, wherein the rotor, the rotor shaft, the rotation board and the circuit board are arranged in the shell body. The rotor is connected to a right shaft end of the rotor shaft, and the circuit board is fixedly arranged at the right side of the rotor. A horizontal shaft hole is formed in the upper end of the shell body, and the rotor shaft is arranged in the horizontal shaft hole in a rotating mode. The rotation board is connected to a left shaft end of the rotor shaft, and the rotation board is arranged by being attached to the outer end face of the left side of the horizontal shaft hole. A clamping spring and a magnetic element are arranged on the rotor, and a Hall element is fixedly connected to the circuit board. A distance exists between the magnetic element and the Hall element, and a sliding increasing cushion is arranged between the rotation board and the horizontal shaft hole. The non-contact throttle position sensor can effectively solve the service life problem caused by abrasion of an existing position sensor, and meanwhile can also solve the drifting problem of signals at a high temperature. The rotation board can rotate flexibly, the phenomenon of clamping will not exist, actions are stable and reliable, sensitivity is high, and the non-contact throttle position sensor is suitable for polarization and application.
Description
Technical field
The present invention relates to a kind of sensor, particularly a kind of contactless throttle position sensor.
Background technology
As everyone knows, throttle position sensor (Throttle Position Sensor, TPS) be installed on the end of throttle plate pin on the throttle body, its function is to import ECU (Electronic Control Unit after changing throttle opening (being engine load) size into electric signal, electronic control unit), ECU differentiates the operating mode of engine according to throttle position signal, as idling operation, partial load condition, high load working condition etc., and according to Under Different Work Condition of Engine the demand of mixture strength is controlled injection time.What existing throttle position sensor generally adopted is the slide rheostat principle, produce output signal by brush in the resistor stripe slip that is printed on the ceramic substrate, owing to be contact between brush and the ceramic substrate, may be worn at long-term friction back brush or resistor stripe, thereby make sensor failure, the working temperature of throttle position sensor is higher, and the electric signal that at high temperature can make sensor output produces skew, thereby influence the output accuracy of throttle position sensor, the elasticity that cooperates between the rotor of sensor and the throttle plate pin can impact signal of sensor, cooperated pine can cause the hysteresis of output signal, sensor is because the restriction of mechanical part, can only measure the certain angle scope, exceed outer can not the measuring of the scope of application, cost is higher in addition, can not satisfy the demand that modern industry is produced.
Summary of the invention
At above-mentioned weak point of the prior art, the invention provides a kind of precision height, bigger, the lower-cost contactless throttle position sensor of measurement range.
To achieve these goals, the invention provides following technical scheme: a kind of contactless throttle position sensor, comprise housing and the rotor of the portion that sets within it, armature spindle, rotor plate and wiring board, this rotor is connected the right side axle head of armature spindle, wiring board fixedly installs on the right of rotor, be provided with horizontal axis hole in the housing upper end, armature spindle is laterally turning setting in the axis hole, rotor plate is connected the left side axle head of armature spindle, rotor plate is pasting laterally, and the outer face, left side of axis hole arranges, rotor is provided with jump ring and magnetic element, be fixedly connected with Hall element in the circuit board, between described magnetic element and the Hall element distance is arranged, at rotor plate and laterally be provided with between the axis hole and increase skidding.
As preferably, described magnetic element is radial polarised magnet body.
By above technical scheme as can be seen, the present invention's novelty simple in structure, can effectively solve the existing position transducer of joint because the life problems that wearing and tearing bring, can also solve simultaneously the drifting problem of the signal when high temperature, this contactless throttle position sensor can realize the output of the signal in the arbitrarily angled scope in 360 ° of scopes by the programming to chip, in addition owing to increase the setting of skidding, when making working sensor, rotor plate rotates bite can not occur flexibly, move reliable and stable, highly sensitive, suitable applying.
