상기와 같은 목적을 달성하기 위하여 본 발명은 상기 자동변속기의 출력축과 추진축을 스플라인 결합시키는 추진축슬라이딩요크의 표면으로 원형의 테두리형상의 타겟휠을 끼워맞추고, 이 추진축슬라이딩요크를 감싸는 더스트커버의 상부로 감지센서를 부착시키도록 된다.In order to achieve the above object, according to the present invention, a circular wheel-shaped target wheel is fitted to a surface of a propeller shaft sliding yoke spline-coupled with an output shaft of the automatic transmission and a propeller shaft, and a dust cover Thereby attaching the detection sensor.
따라서, 추진축이 회전되면 상기 추진축슬라이딩요크에 끼워맞춰진 타겟휠이 함께 회전된다.Therefore, when the propeller shaft is rotated, the target wheel fitted to the propeller shaft sliding yoke is rotated together.
이때, 상기 감지센서는 상기 타겟휠로 펄스를 발사하여 그 거리를 측정하며, 이 측정된 거리의 변화율에 따라 상기 추진축의 진동정도를 측정하도록 된다.At this time, the detection sensor measures a distance of the pulse by emitting a pulse to the target wheel, and measures the degree of vibration of the propeller shaft according to the rate of change of the measured distance.
이에 따라, 상기 연결부가 파손되어 추진축의 진동이 일정진동 이상일 때는 상기 감지센서에 의해 감지되므로 자동변속기의 누유를 방지하도록 된다.Accordingly, when the connection portion is broken and the vibration of the propeller shaft is greater than a predetermined vibration, it is sensed by the detection sensor, thereby preventing leakage of the automatic transmission.
이하 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 시스템 구성을 도시한 구성도로, 익스텐션하우징(1)의 내부에서 회전되는 자동변속기의 출력축(2)과, 앞바퀴로 동력을 전달하는 추진축(3)과 상기 출력축(2)을 연결하는 추진축슬라이딩요크(4), 익스텐션하우징(1)의 선단부(1a)에서 추진축슬라이딩요크(4)를 지지하는 브러시(1b) 및, 상기 익스텐션하우징(1)의 선단부(1a)에 부착되어 추진축슬라이딩요크(4)를 환형으로 감싸는 더스트커버(5)로 이루어진 자동변속기의 연결부(6)의 더스트커버(5) 상단부에 부착되는 감지센서(7)와, 상기 추진축슬라이딩요크(4)에 환형으로 끼워지는 타겟휠(8), 감지센서(7)의 전송신호를 처리하는 콘트롤유닛(9) 및, 이 콘트롤유닛(9)의 제어에 따라 차실내에서 점멸되는 표시등(10)으로 구성된다.Fig. 1 is a diagram showing a system configuration according to the present invention. Fig. 1 is a diagram showing the configuration of a system according to the present invention. The output shaft 2 of the automatic transmission is rotatable in the extension housing 1. The propeller shaft 3 transmits power to the front wheels. A brush 1b for supporting the propeller shaft sliding yoke 4 at the front end 1a of the extension housing 1 and a brush 1b attached to the front end 1a of the extension housing 1 A sensing sensor 7 attached to an upper end portion of a dust cover 5 of a connection portion 6 of an automatic transmission formed of a dust cover 5 annularly enclosing a propeller shaft sliding yoke 4, A control unit 9 for processing the transmission signal of the detection sensor 7 and a display lamp 10 blinking in the vehicle interior under the control of the control unit 9 .
여기서 도 2는 도 1의 I - I선 단면도로, 중앙의 추진축슬라이딩요크(4)와, 이 추진축슬라이딩요크(4)의 환형상으로 감싸는 타겟휠(8), 이 타겟휠(8)을 감싸는 더스트커버(5) 및 이 더스트커버(5)의 상단부(5a)에 부착되는 감지센서(7)가 구성된다.Fig. 2 is a sectional view taken along the line I-I in Fig. 1, showing a central propeller shaft sliding yoke 4, a target wheel 8 surrounding the propeller shaft sliding yoke 4 in an annular shape, The dust cover 5 and the detection sensor 7 attached to the upper end 5a of the dust cover 5 are constituted.
한편, 상기 감지센서(7)는 상기 추진축(3)의 회전에 따라 회전되는 타겟휠(8)의 테두리부로 펄스를 발사하여 그 거리를 측정한다.On the other hand, the sensing sensor 7 emits pulses to the edge of the target wheel 8 rotated according to the rotation of the propulsion shaft 3, and measures the distance.
여기서, 상기 브러시(1b)가 마모되면 상기 추진축(3)의 회전이 비정상적으로 흔들리게 되고, 상기 추진축슬라이딩휠(4)에 부착된 타겟휠(8)도 흔들리게 된다.Here, when the brush 1b is worn, the rotation of the propelling shaft 3 is abnormally shaken, and the target wheel 8 attached to the propelling shaft sliding wheel 4 is also shaken.
따라서, 상기 감지센서(7)에 의한 타켓휠(8)과의 측정거리가 변화하게 되며 이 신호는 상기 콘트롤유닛(9)으로 전송되고 추진축(3) 및 자동변속기의 출력축(2)이 과대하게 흔들린다고 판단되면 운전석의 표시등(10)을 점등된다.Therefore, the distance measured by the sensing sensor 7 with respect to the target wheel 8 changes, and this signal is transmitted to the control unit 9 and the output shaft 2 of the propulsion shaft 3 and the automatic transmission is excessively When it is judged that it is shaken, the indicator light (10) of the driver's seat lights up.
이에 따라, 상기 자동변속기용 오일의 누유를 미연에 방지할 수 있도록 된다.Thus, leakage of the oil for the automatic transmission can be prevented in advance.
이상에서 설명한 바와 같이 본 발명에 의하면 상기 자동변속기의 출력축과, 추진축을 스플라인결합시키는 추진축슬라이딩요크의 표면으로 환형상의 타겟휠을 끼워맞추고, 이 추진축슬라이딩요크를 감싸는 더스트커버의 상부로 감지센서를 부착시키므로 자동변속기의 브러시의 파손에 따른 추진축의 흔들림을 감지하도록 되므로 자동변속기용 오일의 누유를 방지하는 효과가 있다As described above, according to the present invention, the annular target wheel is fitted to the surface of the propeller shaft sliding yoke spline-coupled with the output shaft of the automatic transmission, and the sensing sensor is attached to the upper portion of the dust cover surrounding the propeller shaft sliding yoke So that the shaking of the propeller shaft due to the breakage of the brush of the automatic transmission is detected, thereby preventing oil leakage of the automatic transmission.
