A linear potentiometer for measuring the displacement and a rotary potentiometer for measuring the angle (caster angle, chamber angle, toe angle) displacement of each axis.
이하, 본 발명을 첨부된 도면을 참조하여 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.
전술한 계측기는 광범위한 용도에서 사용될 수 있지만, 본 발명의 실시예에 따른 3차원의 계측기는 통상 자동차의 서스펜션의 변화를 측정하기 위한 장치이며, 자동차의 서스펜션 특히, 피측정물의 변위와 각도를 측정할 수 있도록 하는 계측기에 관한 것이다.Although the above-described measuring instrument can be used in a wide range of applications, the three-dimensional measuring instrument according to an embodiment of the present invention is a device for measuring a change in suspension of a vehicle in general, the suspension of the vehicle, in particular, to measure the displacement and angle It relates to a measuring instrument that allows.
본 발명에 따른 3차원 계측기는 자동차 서스펜션의 위치 변화에 따른 선형 방향의 롤링, 피칭, 요잉과 타이어 각의 변위에 의한 카스터각, 챔버각, 토우각 측정하는 계측기(SPMD:Suspension Parameter Measuring Device)이다.The three-dimensional measuring device according to the present invention is a measuring device (SPMD: Suspension Parameter Measuring Device) measuring the caster angle, the chamber angle and the toe angle due to the displacement of the rolling, pitching, yawing and tire angles in a linear direction according to the position change of the vehicle suspension. .
첨부 도면 1도와 같이, 본 발명에 따른 계측기(10)는 노면 입력에 대한 서스펜션의 변위를 측정하기 위한 측정부(11), 고정부(12), 휠 지그부(13)로 이루어지는 구성으로 되어 있다.As shown in the accompanying drawings, the measuring device 10 according to the present invention has a configuration including a measuring part 11, a fixing part 12, and a wheel jig part 13 for measuring a displacement of a suspension with respect to a road surface input. .

서스펜션의 휠 변위에 따라 X축(롤링), Y축(피칭), Z축(요잉) 방향의 변위는 선형 포텐시오미터로 측정된다.Depending on the wheel displacement of the suspension, displacements in the X-axis (rolling), Y-axis (pitching), and Z-axis (yaw) directions are measured with a linear potentiometer.
각 축의 각도(카스터각, 챔버각, 토우각) 변위에 대해서는 로터리 포텐시오미터로 측정하여 6자유도 3차원 측정이 가능하다.The angle (caster angle, chamber angle, toe angle) displacement of each axis can be measured with a rotary potentiometer, allowing six degrees of freedom and three-dimensional measurements.
상기 포텐시오미터는 저항소자 위를 와이퍼가 섭동하고 분압기로 전자 기기의 회로 전압의 조정, 음압회로의 조정등을 위해 사용되는 일반형의 가변 저항기일 수 있다.The potentiometer may be a general type variable resistor used by the wiper to perturb the resistor element and to adjust the circuit voltage of the electronic device, the adjustment of the negative voltage circuit, etc. with a voltage divider.
상기 계측기의 작동에 있어서, 제1도에 도시된 바와 같이 자동차 서스펜션의 변화에 의해 6자유도의 변위가 생긴다.In the operation of the instrument, as shown in FIG. 1, a displacement of six degrees of freedom occurs due to the change of the vehicle suspension.
