Description
본 발명은 직진성이 좋고 식별력이 뛰어난 빔과 이를 반사시키는 반사경을 이용하여 정상적이지 못한 자동차 바퀴의 camber와 toe를 직접 육안으로 보면서 신속하고 편리하게 보정할수 있도록한 자동차 바퀴 보정(alignment)방법에 관한 것이다.The present invention relates to an automobile wheel alignment method that allows the user to quickly and conveniently see the camber and toe of an abnormal vehicle wheel by visually using a beam having excellent straightness and distinguishing power and a reflector reflecting the same. .
현재까지 실시되고 있는 자동차 바퀴 보정방법을 간략히 설명하면 바퀴 부착용 클램프 자체에 적외선 발생 장치와 반사경을 장치하여 적외선이 반사되도록 함과 동시에 반사된 적외선 반사각을 별도의 센서가 감지하도록 한 후 그 감지 값(데이타)이 컴퓨터에 입력되도록 하고, 감지 값을 입력받은 컴퓨터는 컴퓨터에 이미 저장되어 있는 표준값과 입력값을 비교하여 계산된 측정오차를 모니터에 출력되게 하며 이렇게 모니터에 출력되는 정보에 의거하여 바퀴의 camber와 toe를 보정할수 있도록 하였다.Briefly, the method for calibrating the wheels of a car, which has been carried out to date, is provided with an infrared generator and a reflector attached to the wheel mounting clamp itself so that infrared light is reflected and a separate sensor detects the reflected infrared light reflection angle. Data) is input to the computer, and the computer receiving the detected value compares the input value with the standard value already stored in the computer and outputs the calculated measurement error to the monitor. The camber and toe can be calibrated.
그러나 상기와 같은 종래의 보정방법은 컴퓨터와 모니터가 필요하게 되어 보정장치가 고가로 되는 문제점이 있었음은 물론 중량도 무거워 이동에도 많은 애로점이 있었고 또한 기기의 보관과 유지에도 상당한 비용과 관심이 필요로 하였을 뿐만 아니라 바퀴 보정시작에서 부터 완료까지의 시간이 오래 걸리는 폐단도 있었다However, the conventional calibration method as described above requires a computer and a monitor, so that the calibration device is expensive, and the weight is heavy, causing many difficulties in moving, and also requiring considerable cost and attention in the storage and maintenance of the device. Not only that, but there was also a discontinuation that took a long time from the start of the wheel calibration to the completion.
본 발명은 위와 같이 종래의 자동차 바퀴 보정방법에서 나타나는 문제점과 폐단을 한꺼번에 해결하기 위해 클램프 표면에 부착되는 반사경에 빔이 반사되도록 함과 동시에 반사되는 빔의 반사위치에 의거하여 바퀴를 보정할수 있도록 한것인데 이를 첨부된 도면과 함께 더욱 상세히 설명하면 다음과 같다.The present invention is to solve the problem and the closing end of the conventional car wheel correction method as described above to allow the beam to be reflected on the reflector attached to the clamp surface and at the same time to correct the wheel based on the reflected position of the reflected beam It will be described in more detail with the accompanying drawings as follows.

외측면에 반사경(401)이 부착된 클램프(4)를 보정이 필요한 바퀴에 고정설치하고 반사경(401)의 수평선상 일정거리 외측에는 수평조절이 가능한 수평받침대(2) 상부에 고정되는 보정지지판(1)을 마련하여 그 전면에 보정하고자 하는 자동차 바퀴의 camber와 toe 표준값 즉, camber와 toe의 허용범위(302)(303)가 십자형으로 표현된 보정판(3)을 부착한 다음 보정판(3) 중앙의 빔출사(出射)공(301)으로 보정지지판(1)의 빔출사장치부(101)에서 발생되는 빔(5)을 수평선상의 클램프(4) 외측면 반사경(401)에 출사시킴과 동시에 반사되도록 하여 반사되어 되돌아 오는 빔(5)의 도달점이 보정판(3)의 어느부위에 위치 되느냐에 의거하여 바퀴의 camber와 toe를 보정할수 있도록 한 것이다.The clamp 4 having the reflector 401 attached to the outer surface is fixed to the wheel that requires correction, and a correction support plate fixed to the upper portion of the horizontal support 2 that is horizontally adjustable outside a certain distance on the horizontal line of the reflector 401 ( 1) prepare a camber and toe standard value of the wheel of the car to be calibrated, that is, a correction plate (3) in which the allowable ranges 302 and 303 of the camber and toe are expressed in a cross shape, and then in the center of the correction plate (3). The beam 5 generated by the beam output device 101 of the correction support plate 1 is emitted to the clamp 4 outer surface reflector 401 on the horizontal line and reflected at the same time by the beam exit hole 301 of the The camber and toe of the wheels can be corrected based on which part of the correction plate 3 the point of arrival of the beam 5 reflected and returned.
이와같이된 본 발명을 실시하기 위해 camber와 toe 모두가 정상이 아닌 자동차 바퀴에 클램프(4)를 부착하여 보정판(3) 중앙의 출사공(301)으로 출사되는 빔(5)을 클램프(4) 외측면의 반사경(401)에 반사시키면 반사되어 되돌아와 부딪히는 빔(5)의 도달 위치는 보정판의 camber와 toe의 허용범위(302)(303)를 모두 벗어나게되고 또 바퀴의 camber만 정상이 아닐 때에는 반사되어 되돌아오는 빔(5)의 도달위치는 세로로 표현된 toe허용범위(303) 상측 또는 하측에 위치되게되며 또 toe만이 정상이 아닐 때에는 반사되어 되돌아오는 빔(5)의 도달위치는 가로로 표현된 camber허용범위(302) 좌측 또는 우측에 위치되게되며 camber와 toe가 모두 정상일때는 camber와 toe 허용범위(302)(303)가 교차하는 중앙부가 반사되는 빔(5)의 도달점이 되게된다.In order to implement the present invention as described above, both the camber and the toe attach the clamp 4 to the automobile wheel that is not normal, so that the beam 5 emitted to the exit hole 301 in the center of the correction plate 3 is removed from the clamp 4. When the reflection on the side reflector 401 is reflected, the arrival position of the beam 5, which is reflected and comes back, is out of both the camber of the correction plate and the allowable range 302 (303) of the toe, and when only the camber of the wheel is not normal, it is reflected. The arrival position of the beam 5 to be returned is located above or below the toe allowable range 303 represented vertically, and when the toe is not normal, the arrival position of the beam 5 reflected and returned is represented horizontally. When the camber and toe are both normal, the center of intersection of the camber and the toe tolerance range 302 (303) is the point of arrival of the reflected beam 5.
이렇게 cammber와 toe의 보정범위를 육안으로 직접 인식 할수 있고 또 보정판(3)의 cammber와 toe 허용범위(302)(303)를 벗어나 있는 반사 빔(5)의 도달위치는 바퀴를 물리적으로 교정 하므로서 위치변경이 가능한데 여기서 반사 빔(5)의 위치변경은 곧 바퀴의 cammber와 toe 보정을 의미한다.In this way, the correction range of cammber and toe can be directly recognized by the naked eye, and the arrival position of the reflection beam 5 outside the cammber and toe allowance range 302 (303) of the correction plate 3 is located by physically correcting the wheels. It is possible to change the position of the reflection beam (5) here means the cammber and toe correction of the wheel.
상기에 서술한 자동차 바퀴의 cammber와 toe 보정을 실현하기 위해서는 출사되는 빔(5)은 직진성이 뛰어나고 식별력이 우수하여야 하며 빔(5)을 반사시키는 반사경(401)은 표면이 평면이 되어야하고 또 보정판(3)은 사각판으로서 전면에 표현되는 cammber와 toe의 허용범위(302)(303)는 자동차에 따라 다르게 표현될수 있을뿐만 아니라 cammber는 ±5의 오차가 측정되도록 하였으며 toe는 ±3°가 측정되도록 하였는데,In order to realize the cammber and toe correction of the wheels described above, the beam 5 to be emitted should have excellent straightness and excellent discrimination power, and the reflector 401 reflecting the beam 5 should have a flat surface and a correction plate. (3) is the square plate, and the cammber and toe allowable ranges 302 and 303 expressed on the front can be expressed differently depending on the vehicle, and the cammber has an error of ± 5, and the toe is measured by ± 3 °. I tried to
상기의 오차값을 구하기 위해서 바퀴에 부착된 클램프(4)와 보정판(3)과의 거리(L)를 구하며 거리는 아래식에 따라 계산하여 바퀴에서 부터의 보정판(3) 설치거리를 알 수 있다.In order to obtain the above error value, the distance L between the clamp 4 attached to the wheel and the correction plate 3 is obtained, and the distance can be calculated according to the following equation so that the installation distance of the correction plate 3 from the wheel can be known.
L ≒ 1.765m(0.2:17=L:150).L ≒ 1.765 m (0.2: 17 = L: 150).
따라서 본 발명은 상기한 바와 같이 자동차 바퀴의 cammber와 toe상태 출사되는 빔(5)의 반사 도달점 위치에 의거하여 육안으로 직접 확인할수 있고 또 cammber와 toe 보정도 눈으로 보면서 실시할수 있으므로 바퀴의 cammber와 toe 상태를 신속하고 간편하게 알수있는 이점이 있음은 물론 보정도 용이하게 할 수 있는 장점도 있으며 또한 이와같은 바퀴의 보정방법을 이용하면 부피와 무게가 가볍고 구조도 단순한 보정 설비도 얻을수 있을 뿐만 아니라 휴대도 가능하면서 보관과 유지도 용이하게 할수 있는 보정설비를 얻을수 있는 효과도 있는 것이다.Therefore, the present invention can be directly visually confirmed based on the position of the reflection reaching point of the cam 5 and the toe state of the beam emitted from the automobile wheel as described above, and the cammber and toe correction can be carried out while looking at the eye. Not only does it have the advantage of quickly and easily knowing the toe state, but it also has the advantage of making it easy to calibrate. In addition, the calibration method of such wheels provides not only a volume and weight, but also a simple structure and a simple calibration facility. It also has the effect of obtaining a calibration facility that makes it easy to store and maintain.
