The sensor comprises rotating arms, a potentiometer and a pressure board, the potentiometer is equipped on the one side of the pressure board which is fixed on the brake pedal, the one end of two rotating arms is respectively fixed on a shell and a rotating crank of the potentiometer, the other side is respectively contacted with a wall of the driving chamber and a face of the brake pedal, the included angle of two rotating arms is gamma. The utility model converts the mechanical displacement quantity of the pressure board to the variable quantity of the electric potential difference, furthermore, makes a conversion of the quantity of the pedal at the break, in virtue of the rotating arms and the potentiometer, thereby the utility model provides a special-purpose sensor with the simple structure, convenient smeasurement, accurate and reliable data linear change, the utility model can be used individually, and can be made as the multifunctional detecting device co-operating with other sensors.
Description
Technical field
The utility model relates to a kind of measurement mechanism of displacement, and especially the measurement mechanism of motor vehicle pressure plate displacement belongs to field of measuring technique.
Background technology
The braking quality of motor vehicle is related to the safe driving of motor vehicle, is the important indicator of weighing performances of motor vehicles.Braking inertia during at present, often with brake and the legpower that acts on the pedal are the braking quality test item of estimating motor vehicle.The displacement of pedal can react braking quality and characteristic objectively during brake, but for a long time owing to lacking ripe detection means and device, so never list this sensing range of braking quality in.Be the development that promotes the braking quality detection technique and perfect, the displacement of pedal is included the sensing range of braking quality in when being necessary brake, for this reason, needs development that corresponding testing device is provided.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art and a kind of sensor that is used to detect pedal-displacement is provided.
The alleged problem of the utility model realizes with following technical scheme:
A kind of sensor that is used to detect pedal-displacement, it is made up of pivot arm 1,2, potentiometer 3, pressure plate 10, wherein, potentiometer is installed on a side of pressure plate, pressure plate is fixed on the brake pedal 4, one end of pivot arm 1,2 is fixed with the shell and the turning handle of potentiometer respectively, and the other end contacts with the locular wall of pilothouse and the plate face of brake pedal respectively, becomes angle γ configuration between the pivot arm 1,2.
Avoid accidental shock for preventing potentiometer, the above-mentioned sensor that is used to detect pedal-displacement, described potentiometer has sheath 5, sheath is provided with sleeve 5-1 and axis hole 5-2, the shell of potentiometer 3 is fixed among the sleeve 5-1, turning handle is by stretching out among the axis hole 5-2, and an end of described pivot arm 1,2 is fixed together with the turning handle of sheath and potentiometer respectively.
Be to reduce jacket structure length, the above-mentioned sensor that is used to detect pedal-displacement leaves the space between the turning handle of described potentiometer and the axis hole 5-2, and axle sleeve 6 inserts in the space of turning handles and axis hole and is fixed on the turning handle, and its end and pivot arm 1 are fixed.
The above-mentioned sensor that is used to detect pedal-displacement, the angle γ between the described pivot arm 1,2 are 30～60 degree.
The above-mentioned sensor that is used to detect pedal-displacement, described potentiometer adopts linear wound potentiometer.
The utility model is transformed into the mechanical displacement of brake pedal by pivot arm and potentiometer the variable quantity of potentiometer current potential, owing to adopt linear wound potentiometer, therefore the potential difference (PD) variable quantity is directly proportional with the pivot arm variable angle, so can learn the displacement of pedal easily by the funtcional relationship between the two, it is matched with pedal force, can record correlation parameter important between motor vehicle pedal displacement and the pedal force; The utility model provides special-purpose detecting sensor, development and sound laying the foundation for this detection technique, in addition, it also has simple in structure, convenient test, data linear change, waits advantage accurately and reliably, both can use separately, and also can cooperate and make multifunctional detecting device with other sensor.
Description of drawings

Fig. 2 is the A-A cut-open view among Fig. 1.
Embodiment
Consult Fig. 1,2, potentiometer 3 adopts the Wound-rotor type linear potentiometer, and 11 is the locular wall of pilothouse, and this sensor promptly is installed between locular wall and the pedal.Pressure plate 10 is fixed on the brake pedal 4.The shell of potentiometer 3 is embedded among the sleeve 5-1 of sheath 5, is fixed in the sleeve by trip bolt 7.The upper end of pivot arm 1 contacts with pilothouse locular wall 11, fixedly connected with the flange of sheath sleeve 5-1 in the lower end; The upper end of pivot arm 2 contacts with the plate face of brake pedal 4, fixedly connected with axle sleeve 6 in the lower end, and axle sleeve 6 is sleeved in the turning handle and the space between the axis hole 5-2 of potentiometer, and axle sleeve 6 is fixed on the turning handle of potentiometer by trip bolt 8.9 is fabrication hole, is used for screwing in or dismounting trip bolt 8.After adopting sheath, the acting force of pivot arm 1,2 is applied on the sheath, can prevent that potentiometer from suffering the powerful impact of external force.
Still consult Fig. 1,2, when trampling pressure plate 10, brake pedal 4 is drawn close to the locular wall of pilothouse with pressure plate, the turning handle that pivoted arm 1 drives potentiometer 3 turns clockwise, the mechanical displacement in when brake is converted to current potential quantitative changeization with resistance change by potentiometer, and is scaled the displacement of brake pedal thus.Functional relation between the output voltage V X of potentiometer and the pivot arm angle γ is:
VX＝Kγ；
D＝2Rsinγ/2；
In the formula: the variation factor of resistance value when K-is potentiometer unit's anglec of rotation;
D-is the space distance between brake pedal 4 and the pilothouse locular wall;
R-is the radius of turn of pivot arm 1,2.
