본 고안은 자기식 자동차 변소기 출력축 회전수 검출장치에 관한 것으로,특히 자동차 변속기 출력축의 소정부위에 영구자석을 설치하고 이에 대응하는 변속기 하우징에 자기검출헤드를 장착하여 자동차의 속도측정에 이용되는 변속기 출력축의 회전수를 검출함에 따라 부품수를 절감할 수 있으며,아울러 수명이 반영구적인 자기식 자동차 변속 출력축 회전수 검출장치에 관한 것이다. 일반적으로,차량에는 차량의 속도를 시간당으로 계산하여 나타내는 속도지시계와,차량의 총주행거리를 나타내는 적산계와,차량이 주행한 구간거리를 나타내는 구간거리계가 장착되어 있다.The present invention relates to an apparatus for detecting the output shaft speed of a magnetic automobile transmission, in particular, a permanent magnet is installed at a predetermined portion of the transmission shaft of the automobile and a magnetic detection head is mounted on the transmission housing corresponding thereto to measure the speed of the automobile. The number of parts can be reduced by detecting the rotational speed of the output shaft, and moreover, the present invention relates to a magnetic vehicle variable speed output shaft rotational speed detection device having a semi-permanent lifetime. In general, a vehicle is equipped with a speed indicator that calculates the speed of the vehicle per hour, an integration meter indicating the total running distance of the vehicle, and a segment odometer indicating the distance the vehicle has traveled.
상기와 같은 속도계는 제2도의 (a)에 도시된 바와같이 일반적으로 변속기(101)의 출력축(102)에 형성되어 있는 웜휠(worm wheel)(103)에 웜(worm)(104)을 통해 결합되어 있는 플렉시블축(105)의 회전에 의해 구동하게 되어있다. 즉,변속기의 출력축(102)이 회전하면 웜(104)으로 이 변속기 출력축(102)의 웜휠(103)에 결합되어 있는 플렉시블축(105)도 회전하여 제2도의 (b)와 같은 속도계(106)의 마그네트(107)를 회전시키게 된다. 따라서,상기 마그네트(107)외측의 지침(108)이 붙어있는 로터(109)에 토크가 발생하여 헤어스프링(110)을 내측으로 잡아당긴다. 헤어스프링(110)의 늘어나려는 힘과 로터(109)의 끌어당기는 힘이 균형을 이루는 곳에서 로터(109)는 구동을 멈추고,그 때의 차량의 속도를 나타내게 된다. 그러나,상기와 같은 종래의 속도계에서는 속도계가 변속기 출력축에 치차로 결합되어 있는 플렉시블축의 회전에 의해 구동함에 따라 구조가 복잡하고,또한 치차부분이 마모되어 파손됨에 따라 수명이 짧다는 문제점이 있었다. 이에,본 고안은 상기와같은 문제점을 해결하기 위해 안출된 것으로,변속기 출력축의 소정부위에 영구자석을 장착하고 이에 대응하는 변속기 하우징에 자기검출헤드를 장착하여 자석의 회전에 따라 발생하는 자장을 자기검출헤드를 통해 주기적으로 검출하고 이를 통해 변속기 출력축의 회전수를 검출함에 따라 구조가 간단하고 부품수가 적어 조립이 용이하며,또한 비접촉식이기 때문에 수명이 반영구적인 자석식 변속기 출력축 회전수 검축장치를 제공하는 것을 그목적으로 한다.Such a speedometer is coupled through a worm 104 to a worm wheel 103 formed on the output shaft 102 of the transmission 101, as shown in FIG. It is driven by the rotation of the flexible shaft 105. That is, when the output shaft 102 of the transmission rotates, the flexible shaft 105 coupled to the worm wheel 103 of the transmission output shaft 102 is also rotated by the worm 104, so that the speedometer 106 as shown in FIG. ) Rotates the magnet 107. Accordingly, torque is generated in the rotor 109 to which the guide 108 on the outside of the magnet 107 is attached, and the hair spring 110 is pulled inward. Where the stretching force of the hair spring 110 and the pulling force of the rotor 109 are balanced, the rotor 109 stops driving, indicating the speed of the vehicle at that time. However, in the conventional speedometer as described above, as the speedometer is driven by the rotation of the flexible shaft coupled to the transmission output shaft, there is a problem in that the structure is complicated, and the life is shortened as the gear portion is worn and broken. Therefore, the present invention has been devised to solve the above problems, by mounting a permanent magnet on a predetermined portion of the transmission output shaft and a magnetic detection head mounted on the transmission housing corresponding to the magnetic field generated by the rotation of the magnet magnetic It is possible to provide a semi-permanent magnetic transmission output shaft rotation speed detecting device that is semi-permanent because its structure is simple and easy to assemble due to the small number of parts, as it detects the rotation of the transmission output shaft periodically through the detection head. For that purpose.
상기와 같은 목적을 달성하기 위하여 본 고안은,자동차 변속기 출력축 회전수 검출장치에 있어서,변속기 출력축의 소정부위에 장착되어 있는 영구자석과,상기 영구자석이 장착되어 있는 부위에 대응하는 변속기 하우징에 장착되어 상기 영구자석에 의해 발생하는 자장을 검출하는 자기검출헤드와,상기 자기검출헤드에서 출력되는 신호에 따라 펄스신호를 카운팅하는 제어부를 구비하는 것을 특징으로 한다. 이하,본 고안의 바람직한 일실시예를 첨부된 도면을 참조하여 상세히 설명한다.In order to achieve the above object, the present invention, in the vehicle transmission output shaft speed detection device, a permanent magnet mounted on a predetermined portion of the transmission output shaft, and mounted on the transmission housing corresponding to the portion on which the permanent magnet is mounted And a magnetic detection head for detecting a magnetic field generated by the permanent magnet, and a control unit for counting a pulse signal according to a signal output from the magnetic detection head. Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in detail.
제1도는 본고안에 따른 자석식 자동차 변속기 출력축 회전수 검출장치의 구성을 개략적으로 나타낸 도면으로,변속기 출력축(10)의 소정부위에 일정한 크기를 갖는 영구자석(20)이 장착되어 있으며,상기 영구자석(20)의 장착부위에 대응하는 변속기 하우징(30)에는 영구자석(20)에 의해 발생되는 장을 검출하는 자기검출헤드(40)가 장착되어 있다.1 is a view schematically showing the configuration of the magnetic vehicle transmission output shaft speed detection apparatus according to the present invention, a permanent magnet 20 having a predetermined size is mounted on a predetermined portion of the transmission output shaft 10, the permanent magnet ( The transmission housing 30 corresponding to the mounting portion of the 20 is mounted with a magnetic detection head 40 for detecting a field generated by the permanent magnet 20.
한편,자기검출헤드(40)에는 이 자기검출헤드(40)의 출력신호에 따라 펄스신호를 발생하는 신호변환부(50)가 접속되어 있으며, 이 신호변환부(50)의 출력신호는 제어부(60)로 인가되어 카운팅된다.On the other hand, the magnetic detection head 40 is connected to a signal conversion unit 50 for generating a pulse signal in accordance with the output signal of the magnetic detection head 40, the output signal of the signal conversion unit 50 is a control unit ( 60) and counted.
다음에는 상기와 같이 구성된 본 고안의 작용 및 효과를 상세히 설명하기로 한다.Next will be described in detail the operation and effects of the present invention configured as described above.
엔진이 구동되어 변속기의 출력축(10)이 회전하며, 이 변속기의 출력축(10)에 장착되어 있는 영구자석(20)도 회전하게 된다. 따라서,변속기 하우징(30)에 장착되어 있는 자기검출헤드(40)는 영구자석(20)의 접근에 따라 주기적으로 영구자석(20)에 의해 발생되는 자장을 검출하고 그에따른 신호를 출력하게 된다.The engine is driven to rotate the output shaft 10 of the transmission, and the permanent magnet 20 mounted on the output shaft 10 of the transmission also rotates. Therefore, the magnetic detection head 40 mounted on the transmission housing 30 periodically detects the magnetic field generated by the permanent magnet 20 according to the approach of the permanent magnet 20 and outputs a signal accordingly.
한편,신호변환부(50)는 자기검출헤드(40)의 출력신호를 펄스신호로 변환하여 제어부(60)로 인가한다. 따라서,제어부(60)가 신호변환부(50)에서 출력되는 펄스신호를 카운팅하면 변속기 출력축의 회전수를 인지할 수 있게 된다.On the other hand, the signal converter 50 converts the output signal of the magnetic detection head 40 into a pulse signal and applies it to the controller 60. Therefore, when the controller 60 counts the pulse signal output from the signal converter 50, the controller 60 can recognize the rotation speed of the transmission output shaft.
상기와 같이 본 고안은,변속기 출력축의 소정부위에 영구자석을 장착하고 이에 대응하는 변속기 하우징에 자기검출헤드를 장착하여 자석의 회전에 따라 발생하는 자장을 자기검출헤드를 통해 주기적으로 검출하고 이를통해 변속기 출력축의 회전수를 검출함에 따라 구조가 간단하고 부품수가 적어 조림이 용이하며,또한 비접촉식이기 때문에 수명이 반영구적이다.As described above, the present invention, by mounting a permanent magnet on a predetermined portion of the transmission output shaft and a magnetic detection head in the corresponding transmission housing to periodically detect the magnetic field generated by the rotation of the magnet through the magnetic detection head and through this By detecting the rotational speed of the transmission output shaft, the structure is simple, the number of parts is easy to simmer, and the non-contact life is semi-permanent.
본 고안은 도면에 도시된 일실시예를 참고로 설명되었으나 이는 예시적인것에 불과하며,당해 기술분야에 통상의 지식을 지닌자라면 이로부터 다양한 변형 및 균등한 타실시예가 가능하다는 점을 이해할 것이다. 따라서,본 고안의 진정한 기술적 보호범위는 첨부된 실용신안등록청구의 범위에 의해서만 정해져야 할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is only an example, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
