[발명이 속하는 기술분야 및 그 분야의 배경기술]TECHNICAL FIELD OF THE INVENTION AND BACKGROUND BACKGROUND
본 발명은 자동차 휠의 얼라이먼트를 측정하는 휠 얼라이먼트 측정 센서의 측정 기준이 되는 영점 입력을 하기 위한 센서의 셋팅 방법 중 토우센서의 영점 입력을 하기 위한 센서의 셋팅 방법을 제안한 것으로서 보다 구체적으로는 토우센서에 조사되는 광선 즉 LED를 이용하여 센서를 개별적으로 영점 셋팅하여 동일한 영점 입력을 할 수 있도록 한 것이다.The present invention proposes a sensor setting method for zero input of a tow sensor among a sensor setting method for zero input which is a measurement reference of a wheel alignment measurement sensor for measuring alignment of an automobile wheel, and more specifically, a tow sensor. It is to set the sensor individually by using light rays irradiated to the LED, so that the same zero input can be made.
휠 얼라이먼트의 측정이라 함은 자동차의 자동차 바퀴의 정렬상태를 측정하는 것으로서 통상 자동차의 바퀴는 토우인, 캠버각, 킹핀경사각, 캐스터각, 쓰러스트각 등 기하학적 선과 각도가 주행함으로서 발생하는 역학으로 자동차 주행성능 및 조향성능이 우수하게 하기 위하여 바퀴의 전,후 및 상,하로 소정의 경사각을 가지며 장착된다.The wheel alignment measurement is a measure of the alignment of the wheels of a car. In general, the wheels of a car are driven by dynamics generated by geometric lines and angles such as toe-in, camber angle, king pin inclination angle, caster angle, and thrust angle. In order to improve the performance and steering performance, the wheels are mounted with predetermined inclination angles before, after, and up and down.
따라서 자동차의 사용중에도 최초의 자동차 설계시에 주어진 토우인 등 경사각도를 유지하는 것이 가장 적절하나 주행여건상 사고의 발생 및 노면의 충격 등으로 인하여 상기의 휠 얼라이먼트는 설정된 경사각도에서 쉽게 변화하게 되고 이는 주행성능 및 조향성능의 저하와 타이어의 편마모, 핸들 복원성의 저하 등 다양한 문제점을 발생시키게 되며 이를 최초 설정치로 조정할 수 있도록 바퀴가 가지고 있는 각도를 측정하는 것이 휠 얼라이먼트의 측정이라 하며, 본 발명은 휠 얼라이먼트를 조정하기 위하여 휠 얼라이먼트의 변형량을 측정하는 센서들 중에서 토우센서의 측정 기준점이 되는 영점 입력이 모두 동일하고 사후관리에 편리하도록 하는 개별 휠 얼라이먼트 센서의 토우센서 영점 입력 방법에 관한 것이다.Therefore, it is most appropriate to maintain the inclination angle such as the toe-in given during the initial design of the vehicle even when the vehicle is in use.However, the wheel alignment is easily changed at the set inclination angle due to the occurrence of an accident and the impact of the road surface. Various problems such as deterioration of driving performance and steering performance, deterioration of tire wear and handle restorability are generated, and measuring the angle of the wheel so that it can be adjusted to the initial set value is called wheel alignment measurement. The present invention relates to a tow sensor zero input method of an individual wheel alignment sensor, in which the zero inputs, which are the measurement reference points of the toe sensors, among the sensors measuring the deformation amount of the wheel alignment for the alignment are all the same and are convenient for the post-management.
일반적으로 휠 얼라이먼트의 센서는 영점 즉 측정기준점은 지그를 이용하여 4개씩 쌍으로 하여 상대적으로 영점을 셋팅하는 것이 일반적이고, 셋팅된 휠 얼라이먼트 센서 또한 반복하여 사용함으로서 영점이 변화하거나, 고장 수리 후에는 영점을 4개씩 상대적으로 재셋팅하여 주어야한다.In general, the wheel alignment sensor is set to zero, that is, the reference points are set in pairs by four using a jig, and the zero point is generally set by repeatedly using the set wheel alignment sensor. The four zeros should be reset relatively.
따라서 휠 얼라이먼트의 센서를 영점셋팅하기 위하여 종래에는 도1에서와 같이 자동차의 전륜과 후륜의 차축 기능을 하는 장치축(101')을 가진 장방형의 지그(1')를 제작하고 지그를 수평계(102')를 이용하여 수평의 평형상태를 유지하게 장치하고 지그의 장치축(101')에 4개의 센서를 모두 장치하여 휠 얼라이먼트 센서의 토우센서를 상대적으로 영점을 셋팅하였다.Therefore, in order to zero-set the sensor of the wheel alignment, as shown in Fig. 1, a rectangular jig 1 'having a device shaft 101' functioning as an axle of a front wheel and a rear wheel of a vehicle is manufactured and the jig is leveled. ') Was used to maintain the horizontal equilibrium state and all four sensors were installed on the device shaft 101' of the jig, and the tow sensor of the wheel alignment sensor was relatively set.
그러나 상기와 같이 되는 종래의 휠 얼라이먼트 센서의 토우센서 영점 셋팅 방법은 지그를 정밀하게 가공하여 지그의 정밀도에 의해 또 다른 측정 기구인 휠 얼라이먼트 센서의 토우센서의 측정 기준이 되는 영점을 상대적으로 입력하였으므로 지그의 변형, 설치 오차 등이 발생하게 되며, 특히 상대적인 센서와 대향되게 영점이 설정되어 있어 정확한 영점 입력에 대한 검증이 어려우며, 또한 반드시 대 향의 센서와 동시에 설치, 작동이 되어야만 토우값을 측정할 수밖에 없는 문제점이 있었다.However, the conventional method for setting the toe sensor zero point of the wheel alignment sensor according to the related art precisely processes the jig and inputs the zero point, which is a measurement reference of the toe sensor of the wheel alignment sensor, which is another measuring mechanism by the precision of the jig. Jig deformation, installation error, etc. occur, especially since the zero point is set opposite to the relative sensor, it is difficult to verify the correct zero input, and the tow value must be installed and operated simultaneously with the opposite sensor. There was nothing but a problem.
본 발명은 상기와 같은 종래의 결점을 개선하여 절대적인 기준점이 설정된 발광부 LED를 이용하여 개별 휠 얼라이먼트 토우센서들이 모두 동일한 영점 값을 가질 수 있도록 함으로서 4개의 휠 얼라이먼트 센서들 뿐만 아니라 모든 얼라이먼트 센서들이 모두 동일한 영점 입력이 가능하도록 하는 휠 얼라이먼트 센서의 토우센서 영점 셋팅 방법을 제안함에 그 목적이 있다.The present invention improves the conventional drawbacks as described above, so that the individual wheel alignment toe sensors can all have the same zero value by using the light emitting unit LED in which the absolute reference point is set, so that not all the wheel alignment sensors but all the alignment sensors are all It is an object of the present invention to propose a toe sensor zero setting method of a wheel alignment sensor to enable the same zero point input.
상기와 같은 목적을 달성하기 위하여 본 발명은 직진성이 우수하고 종래 휠 얼라이먼트 센서에 사용중인 적외선 광선 LED 광선을 이용하여 휠 얼라이먼트 센서의 토우센서 영점을 입력할 수 있도록 한 것인데 이를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다In order to achieve the above object, the present invention is to enable to input the tow sensor zero of the wheel alignment sensor by using an infrared ray LED light beam having excellent straightness and the conventional wheel alignment sensor based on the accompanying drawings Detailed description is as follows.
즉 본 발명은 장치구 A면(1)과 직각으로 설치한 장치구 B면(2)으로 된 직각 기구물로 이루어진 장치구 A면(1)의 중심부에 발광부 LED(3)을 설치하고 장치구 B면(2)에서 발광부 LED(3)와 동일거리에 휠 얼라이먼트 센서의 토우센서 수광부 CCD(4) 중심부를 설치하게 형성하여 발광부 LED(3)와 토우센서 수광부 CCD(4)가 수직으로 형성되게 장착하고 장치구 A면(1)의 발광부 LED(3)에서 LED 적외선을 조사하면(301) 장치구 B면(2) 토우센서 수광부 CCD(4)에 상이 맺혀지게 되는데 이때 맺 혀진 상의 위치가 토우센서 수광부 CCD(4) 중심부에 위치하도록 영점을 입력할 수 있게 형성하여 구성된다.That is, in the present invention, the light emitting
상기와 같이 되는 본 발명은 절대적인 기준점이 설정된 LED 광선을 이용하여 휠 얼라이먼트 센서의 토우센서 영점을 모두 동일하게 입력함으로서 모든 휠 얼라이먼트 센서들이 동일한 영점값을 가지게 되므로, 기존의 휠 얼라이먼트 센서의 대향에 의한 상대적인 토우센서 영점 입력값으로 인하여 각각의 센서마다 다르게 영점이 입력되어 휠 얼라이먼트 센서를 한 장소에서 2대, 3대 등 다수로 사용하는 경우에 각 센서가 고장이 나거나, 영점의 변형 등에 의해 휠 얼라이먼트 센서를 사용할 수 없게 되는 경우, 동일 위치에 따른 다른 센서를 대용하거나, 따로 공급하여 교체하여도 모두 동일한 정밀도를 유지하게 되어 그 문제를 해결할 수 있게 된다.According to the present invention as described above, all the wheel alignment sensors have the same zero value by inputting the same tow sensor zeros of the wheel alignment sensor using the LED beams at which the absolute reference points are set, so that the conventional wheel alignment sensors are opposed to each other. Due to the relative toe sensor zero input value, each sensor has a different zero point. When using two or three wheel alignment sensors in one place, each sensor fails or wheel alignment is caused by deformation of the zero point. When the sensor becomes unavailable, even if the other sensor according to the same position is replaced or supplied separately and replaced, the same accuracy can be maintained, thereby solving the problem.
..
현재 국내에도 수십종의 휠 얼라이먼트 기계들이 정비업소에서 사용중이나 측정값을 검증할 수 있는 시스템이 없다. 따라서 본 고안을 적용하면 특히 토우센서의 측정 정밀도 부분을 신뢰할 수 있는 시스템으로 활용이 가능하다.At present, dozens of wheel alignment machines are in use in service shops, but there is no system to verify the measured values. Therefore, if the present invention is applied, the measurement precision part of the tow sensor can be utilized as a reliable system.
도1은 종래 지그에 의한 휠 얼라이먼트 센서의 4개씩 동시에 토우센서 영점 입력을 셋팅하는 예시도1 is an exemplary diagram of setting the toe sensor zero input at the same time for each of four wheel alignment sensors by a conventional jig.
도2는 본 고안의 실시예를 나타낸 예시도2 is an exemplary view showing an embodiment of the present invention
