본 발명은 주행하는 타이어가 노면과 접촉하여 생기는 마찰력과 변위를 측정하기 위한 타이어의 마찰에너지 측정 센서구조에 관한 것으로, 더욱 상세하게는 멀티센서 구조를 갖추어 변위감지와 압력감지가 동시에 이루어지는 타이어의 마찰에너지 측정센서 구조에 관한 것이다.The present invention relates to a friction energy measurement sensor structure of a tire for measuring the friction force and displacement caused by the running tire in contact with the road surface, and more particularly has a multi-sensor structure friction of the tire at the same time displacement and pressure sensing The present invention relates to an energy measuring sensor structure.

주행하는 타이어는 타이어의 접지중심을 구심점으로 차량하중에 의한 수직방향의 힘(Fz)과 전후방향의 힘(Fx), 그리고 좌우방향의 힘(Fy)이 발생하게 되며, 여기서 타이어의 전후방향 힘(Fx)과 좌우방향의 힘(Fy)은 제/구동과 코너링과 같은 차량운동에 의해 큰 영향을 받게 된다.The running tire generates the vertical force (Fz), the force in the front-rear direction (Fx), and the force in the left-right direction (Fy) due to the vehicle's load at the center of the tire's ground. (Fx) and the force in the left and right directions (Fy) are greatly influenced by vehicle movements such as driving / driving and cornering.

이와 아울러 타이어의 트레드 블록은 주행시 노면과 접촉하면서 전후방향(Dx)과 좌우방향(Dy)으로 각각 변위를 발생하게 된다.In addition, the tread block of the tire is in contact with the road surface while driving to generate displacements in the front and rear directions Dx and the left and right directions Dy, respectively.

따라서 주행시 타이어에 발생하는 이러한 힘들과 변위들을 측정하여 타이어의 마찰에너지를 계산하는 것은 타이어의 마모성능을 예측하는데 활용되고 있으며, 이러한 각각의 힘과 변위를 측정하기 위해서 종래에도 타이어의 마찰에너지 측정센서를 이용하였다.Therefore, calculating the friction energy of the tire by measuring the forces and displacements generated in the tire while driving is utilized to predict the wear performance of the tire. In order to measure the respective force and displacement, the friction energy measurement sensor of the tire is conventionally used. Was used.

종래 타이어의 마찰에너지 측정센서는 도 4에 도시된 바와 같이 받침 지지대(101)에 상부 지지대(105)가 미세 조정부(103)를 매개로 설치되는데, 이 상부 지지대(105)에는 타이어 수직방향의 힘 감지부(Fx)과 전후방향의 힘 감지부(Fy) 및 좌우 방향의 힘 감지부(Fz), 그리고 단일판 구조의 타이어 블록 전후방향 변위 감지부(Dx)와 좌우방향 변위 감지부(Dy)들이 설치되어 있으며, 이들 감지부들은 스트레인 게이지로 이루어져 있었다.In the conventional tire friction energy measurement sensor as shown in Figure 4, the upper support 105 is installed on the support base 101 via the fine adjustment unit 103, the upper support 105 in the vertical force of the tire The sensing unit Fx, the force sensing unit Fy in the front and rear directions, the force sensing unit Fz in the left and right directions, and the tire block front and rear displacement detectors Dx and the left and right displacement detectors Dy having a single plate structure.
