본 발명은 비교적 매우 저렴한 비용으로 차량에 용이하게 장착 및 제거할 수 있고, 차량 개발시 주행중인 차량휠의 각도 변화를 저렴하고 용이하게 측정할 수 있도록 한 차량휠의 각도변화 측정장치를 제공한다.The present invention provides an apparatus for measuring angle change of a vehicle wheel, which can be easily installed and removed in a vehicle at a relatively very low cost, and can measure the change in angle of a vehicle wheel that is in operation at a low cost and easily.

도 1 내지 도 3을 참조하면, 본 발명 실시예는 차량휠(1)의 회전중심과 동심축을 이루는 회전축을 가지고 상기 차량휠(1)에 장착되는 장착부(3)와; 상기 장착부(3)의 회전축을 회전 가능하게 지지하는 센서패널(5)과; 상기 센서패널(5)에 장착된 자이로센서(7)와; 상기 센서패널(5)이 상기 차량휠(1)과 함께 회전하지 않으면서, 상기 차량휠(1)의 각도변화에 따라 함께 회동되는 것을 허용하는 상태로, 상기 센서패널(5)을 차체에 고정하는 고정수단을 포함하여 구성된다.1 to 3, an embodiment of the present invention includes: a mounting part (3) mounted to the vehicle wheel (1) having a rotation axis concentric with a rotation center of the vehicle wheel (1); A sensor panel 5 rotatably supporting the rotating shaft of the mounting portion 3; A gyro sensor 7 mounted to the sensor panel 5; Fixing the sensor panel 5 to the vehicle body in a state that allows the sensor panel 5 to be rotated together in accordance with the angle change of the vehicle wheel 1 without rotating with the vehicle wheel 1. It is configured to include a fixing means.

즉, 상기 장착부(3)에 의해 상기 자이로센서(7)를 센서패널(5)을 통해 차량휠(1)과 함께 거동할 수 있도록 하되, 차량의 주행에 따른 상기 차량휠(1)의 회전만큼은 독립적으로 자유롭게 허용될 수 있도록 구성한 것이다.That is, the gyro sensor 7 may be moved together with the vehicle wheel 1 through the sensor panel 5 by the mounting unit 3, but as much as the rotation of the vehicle wheel 1 according to the driving of the vehicle is performed. It is configured to be freely allowed independently.

상기 장착부(3)는 도시된 바와 같이 차량휠(1)과 평행한 플레이트 형상으로 형성하여 그 회전중심축이 차량휠(1)의 회전중심과 일치하도록 장착되는 것이 바람직하다.The mounting portion 3 is preferably formed in a plate shape parallel to the vehicle wheel 1 as shown, so that its center of rotation coincides with the center of rotation of the vehicle wheel 1.

상기 자이로센서(7)는 도 3에 예시된 바와 같이 직교하는 3축에 대한 각속도를 측정하여 출력하는데, 상기 측정 가능한 직교하는 3축 중 어느 한 축이 상기 차량휠(1)의 회전축과 동심축을 이루고, 다른 한 축은 차량휠(1)의 회전축에 수평하게 교차되도록 상기 센서패널(5)에 장착된다.The gyro sensor 7 measures and outputs an angular velocity with respect to three orthogonal axes as illustrated in FIG. 3, wherein any one of the three orthogonal orthogonal axes that is concentric with the rotation axis of the vehicle wheel 1. The other axis is mounted on the sensor panel 5 so as to cross horizontally with the rotation axis of the vehicle wheel 1.

물론, 직교하는 3축 중 두 축이 상기한 바와 같이 설정되면, 나머지 한 축은 차량휠(1)의 회전축에 상하방향으로 교차하도록 설정된다.Of course, if two of the three orthogonal axes are set as described above, the other one is set to intersect the axis of rotation of the vehicle wheel 1 in the up and down direction.

본 실시예에서 상기 고정수단은 일단이 차체에 고정된 고정지그(9)와, 상기 고정지그(9)를 상기 센서패널(5)에 연결하는 볼조인트(11)를 포함하여 구성되는데, 여기에 상기 고정지그(9)와 상기 볼조인트(11) 사이에는 상기 차량휠(1)의 거동에 따른 상기 센서패널(5)의 변위를 흡수할 수 있는 플랙시블한 재질의 유연부재(13) 가 더 구비되어 있다.In the present embodiment, the fixing means includes a fixing jig 9 having one end fixed to the vehicle body and a ball joint 11 connecting the fixing jig 9 to the sensor panel 5. Between the fixing jig 9 and the ball joint 11, a flexible member 13 made of a flexible material capable of absorbing displacement of the sensor panel 5 according to the behavior of the vehicle wheel 1 is further included. It is provided.

이는 상기 차량휠(1)이 차량의 주행상태에 따라 그 자세를 달리할 때, 상기 볼조인트(11)에 의해 상기 센서패널(5) 및 장착부(3)가 상기 고정지그(9)에 대하여 차량휠(1)과 함께 자유롭게 자세를 변경할 수 있도록 하지만, 이것이 충분하지 않은 경우에 상기 유연부재(13)가 나머지 필요한 변위를 자유롭게 흡수해 줄 수 있도록 하기 위한 것이다.This is because when the vehicle wheel 1 changes its posture according to the driving state of the vehicle, the sensor panel 5 and the mounting portion 3 are connected to the fixing jig 9 by the ball joint 11. It is possible to freely change the posture with the wheel 1, but in case this is not enough, the flexible member 13 can freely absorb the remaining necessary displacement.

상기한 바와 같이 구성된 본 발명 차량휠(1)의 각도변화 측정장치의 작용을 살펴보면 다음과 같다.Looking at the operation of the angle change measuring device of the vehicle wheel 1 of the present invention configured as described above are as follows.

주행상태에서 자세 변화에 따른 캠버나 토우 등의 각도 변화를 측정하고자 하는 차량휠(1)에 상기한 바와 같이 장착부(3)를 장착하고 자이로센서(7)의 축을 설정하면, 상기 자이로센서(7)의 3축 중 차량휠(1)의 회전축에 수평하게 교차하는 축에 대해 차량휠(1)이 회동하는 양은 캠버의 변화량이 되고, 차량휠(1)의 회전축에 상하방향으로 교차하는 축에 대한 차량휠(1)의 회동량은 토우의 변화량이 된다.When the mounting unit 3 is mounted on the vehicle wheel 1 to measure the angle change of the camber or the tow according to the posture change in the driving state and the axis of the gyro sensor 7 is set, the gyro sensor 7 The amount by which the vehicle wheel 1 rotates with respect to the axis that intersects the rotation axis of the vehicle wheel 1 horizontally among the three axes of) becomes the change amount of the camber, and the axis that crosses the rotation axis of the vehicle wheel 1 in the vertical direction. The amount of rotation of the vehicle wheel 1 with respect to is the change amount of the tow.

여기서, 상기 자이로센서(7)가 차량휠(1)의 자세변화에 따라 출력하게 되는 값은 직교하는 세 축에 대한 각각의 각속도가 되므로, 상기 자이로센서(7)의 각 축에 대한 각속도 출력값을 각각 시간에 대하여 적분하면, 그 방향으로의 각도변화가 계산되고, 이것은 결국 캠버와 토우가 된다.The gyro sensor 7 outputs the angular velocity with respect to three axes that are orthogonal to each of the three orthogonal axes, and thus outputs the angular velocity output value for each axis of the gyro sensor 7. Integrating with respect to time, respectively, calculates the angular change in that direction, which results in camber and toe.

즉, 상기 차량휠(1)의 회전축에 수평하게 교차하는 축에 대해 출력된 값을 시간에 대해 적분하면, 캠버가 되는 것이며, 상기 차량휠(1)의 회전축에 상하방향으로 교차하는 축에 대해 출력된 값을 시간에 대해 적분하면, 토우가 되는 것이다.That is, if the value output for the axis that intersects the axis of rotation of the vehicle wheel 1 horizontally is integrated with time, it becomes a camber, and for the axis that intersects the axis of rotation of the vehicle wheel 1 in the vertical direction. Integrating the output over time gives us toe.

따라서, 본 발명에 의하면 상기한 바와 같이 자이로센서(7)의 3축을 차량휠(1)에 적절히 설정한 상태에서 각 축에 대해 출력되는 값을 시간에 대해 적분함으로써, 캠버와 토우를 차량의 주행상태에서 간단하고 저렴한 방법으로 얻어낼 수 있다.Therefore, according to the present invention, by integrating the values output for each axis with respect to time in the state where three axes of the gyro sensor 7 are properly set to the vehicle wheel 1 as described above, the camber and the tow are driven by the vehicle. It can be obtained in a simple and inexpensive way.
