    • An apparatus and method uses a pair of transducers, such as lasers, mounted on the tire/wheel assembly of a moving vehicle for measuring the actual angles of camber experienced by the vehicle tire as the vehicle moves along an actual road surface. The pair of lasers are mounted in a predetermined horizontal spaced relationship on a bracket mounted on and extending perpendicularly outwardly from a non-rotating hub mounted on the tire/wheel assembly. The reflected laser beams from the pair of lasers are continually measured as the vehicle moves along the road surface. The reflected beams determine the change in spacings of the two lasers above the road surface from which can be calculated the angles of camber continuously imparted on the tire/wheel assembly. This data is collected and stored in a computer located in the vehicle and captures the tire's operating camber angles with respect to an actual road surface when used on a particular vehicle. The stored data is later supplied to tire test equipment at a remote test facility to duplicate the actual road camber experienced on the test tire on other test tires at the test facility to simulate the real-world environment for a particular tire on a particular vehicle without repeating the more costly tests on the actual moving vehicle at a remote test track.
    • 装置和方法使用安装在移动车辆的轮胎/车轮组件上的一对换能器,例如激光器,用于测量当车辆沿着实际路面移动时由车辆轮胎经历的实际角度。 一对激光器以安装在安装在轮胎/轮组件上的非旋转轮毂的垂直向外安装在支架上的预定水平间隔关系安装。 当车辆沿着路面移动时,来自一对激光器的反射激光束被连续测量。 反射光束确定路面上方的两个激光器的间隔的变化,可从该距离计算连续施加在轮胎/轮组件上的弧角。 该数据被收集并存储在位于车辆中的计算机中,并且当在特定车辆上使用时捕获相对于实际路面的轮胎的操作外倾角。 存储的数据随后提供给远程测试设备的轮胎测试设备,以复制测试设备上的其他测试轮胎上测试轮胎上经历的实际路面弯度,以模拟特定车辆上的特定轮胎的真实环境,而不会 在远程测试轨道上重复对实际移动车辆的更昂贵的测试。
