Abstract
The utility model discloses an automobile throttle position sensor which comprises a shell, a rotor, a rotor shaft, a rotary plate and a circuit board, wherein the upper end of the shell is provided with a horizontal shaft hole; the rotor shaft can be rotatably arranged in the shaft hole; the rotor is connected to the right side shaft end of the rotor shaft; the circuit board is fixedly arranged on the right side of the rotor; the rotor is provided with an electric brush wire which is in sliding contact with a resistor sheet on the surface of the circuit board; the output of the circuit board is connected with a plug through an electric brush sheet; the rotor is connected with a torsional spring; and the rotary plate is connected to the left side shaft end of the rotor shaft. The automobile throttle position sensor is characterized in that the rotary plate is attached to the outer end surface of the left side of the horizontal shaft hole; and a sliding enhancing gasket is arranged between the rotary plate and the outer end surface of the left side of the horizontal shaft hole. Compared with the conventional throttle position sensor, the automobile throttle position sensor provided by the utility model has the advantages that the rotary plate rotates flexibly, can not be clamped, the movement is stable and reliable, and the flexibility is high.
Description
Technical field
The utility model relates to a kind of position transducer of using at air throttle of car.
Background technology
Throttle position sensor is called again engine load sensor or throttle switch, and its main function is to detect engine to be in idling operation or load condition, is accelerating mode or decelerating mode.Traditional air throttle position sensor of automobile, comprise housing, rotor, armature spindle, rotor plate and wiring board, the housing upper end is provided with horizontal axis hole, armature spindle is laterally rotatably arranging in the axis hole, described rotor is connected to the right side axle head of armature spindle, wiring board is fixedly installed on the right of rotor, rotor is provided with brush wires and contacts with the resistor disc of PCB surface is moving, the output of wiring board is connected with plug by brush plate, be connected with torsion spring on the rotor, described rotor plate is connected to the left side axle head of armature spindle, and rotor plate is directly pasting laterally outer face, the left side setting of axis hole.In the said structure, because rotor plate is directly to paste laterally outer face, the left side setting of axis hole, so rotor plate unavoidably is subject to when rotating and outer face, horizontal axis hole left side between the impact that rubs, occur easily rotating the not smooth phenomenon of bite, thereby cause the sensitivity of sensor; If rotor plate is not adjacent to the outer face, left side of horizontal axis hole, rotor easily produces axial float, and the action of sensor is unstable reliable.In addition, in the tradition throttle position sensor, be that the resistor disc of assurance brush wires and PCB surface is realized reliably moving the contact, rotor is provided with Compress Spring with the right side inner face of horizontal axis hole, the shortcoming of Compress Spring is: axial dimension is large, and the prestress that applies is wayward.
Summary of the invention
In view of the deficiencies in the prior art, the utility model provides a kind of rotor plate to rotate bite can not occur flexibly, and having stable behavior is reliable, highly sensitive air throttle position sensor of automobile.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
A kind of air throttle position sensor of automobile, comprise housing, rotor, armature spindle, rotor plate and wiring board, the housing upper end is provided with horizontal axis hole, armature spindle is laterally rotatably arranging in the axis hole, described rotor is connected to the right side axle head of armature spindle, wiring board is fixedly installed on the right of rotor, rotor is provided with brush wires and contacts with the resistor disc of PCB surface is moving, the output of wiring board is connected with plug by brush plate, be connected with torsion spring on the rotor, described rotor plate is connected to the left side axle head of armature spindle, it is characterized in that: rotor plate is pasting laterally outer face, the left side setting of axis hole, is provided with between the outer face, left side of rotor plate and horizontal axis hole to increase the skidding sheet.The described skidding sheet that increases adopts polytetrafluoroethylmaterial material, and the thickness that increases the skidding sheet is 3-5mm.Be provided with waveform bullet pad between the right side inner face of described rotor and horizontal axis hole.
In the technique scheme, at rotor plate and laterally set up between the outer face, left side of axis hole and increase the skidding sheet, increase the skidding sheet and made by the very little polytetrafluoroethylmaterial material of friction factor, so during working sensor, rotor plate rotates bite can not occur flexibly, and having stable behavior is reliable, and is highly sensitive.Also have, replace the Compress Spring of prior art with waveform bullet pad, advantage is: greatly dwindle axial dimension, the prestress that waveform bullet pad applies is easy to control.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is structural drawing of the present utility model.
Embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, and the below further describes each details and the principle of work thereof of embodiment more by reference to the accompanying drawings.
As shown in the figure, air throttle position sensor of automobile of the present utility model, comprise housing 1, rotor 7, armature spindle 2, rotor plate 4 and wiring board 8, housing 1 upper end is provided with horizontal axis hole 12, armature spindle 2 is in laterally axis hole 12 interior rotatable settings, described rotor 7 is connected to the right side axle head of armature spindle 2, wiring board 8 is fixedly installed on the right of rotor 7, rotor 7 is provided with brush wires 9 and contacts with the resistor disc on wiring board 8 surfaces is moving, the output of wiring board 8 is connected with plug 11 by brush plate 10, be connected with torsion spring 5 on the rotor 7, described rotor plate 4 is connected to the left side axle head of armature spindle 2, rotor plate 4 is pasting laterally, and the outer face, left side of axis hole 12 arranges, be provided with between the outer face, left side of rotor plate 4 and horizontal axis hole 12 and increase skidding sheet 3, the described skidding sheet 3 that increases adopts polytetrafluoroethylmaterial material, and the thickness that increases the skidding sheet is 3-5mm, is provided with waveform bullet pad 6 between the right side inner face of described rotor 7 and horizontal axis hole 12.
The utility model is like this work: rotor plate rotates with the variation of throttle position, rotational angle is corresponding one by one with the position of air throttle, the rotation of rotor plate makes again rotor rotate, so brush wires is slided at the resistor disc of PCB surface, the variation that utilizes resistance converts the positional information of air throttle to voltage signal and exports, output is with respect to the voltage signal of the different corners of air throttle, just according to the load of signal voltage value identification engine, variation gradient identification within a certain period of time is accelerating mode or decelerating mode to computing machine according to signal voltage.
