    • An inventive headlight optical axis aiming measuring apparatus and method is disclosed. The apparatus includes a head measuring horizontal and vertical inclinations of a front lens surface (34) of a headlight (12) installed in a vehicle (2) and including a plurality of contact-type displacement sensors (48, 49, 50, 51), each of which is associated with a device (28, 29, 30) in contact with the front lens surface (34) and moving in accordance with the inclinations of the front lens surface (34), a support (15) for the displacement sensors (48, 49, 50, 51), and device for checking the headlight optical axis aiming in accordance with a fixed relationship between inclinations of a headlight optical axis and the front lens surface (34) by means of outputs of the measuring head (9). In accordance with this invention, the headlight need ot come on and a large space is not required for projecting the headlight beam onto a screen.
    • 公开了一种创造性的前照灯光轴瞄准测量装置和方法。 该装置包括测量安装在车辆(2)中并包括多个接触型位移传感器(48,49,50,51)的头灯(12)的前透镜表面(34)的水平和垂直倾斜度的头部, ,每个与与前透镜表面(34)接触并且根据前透镜表面(34)的倾斜度移动的装置(28,29,30),用于位移的支撑件(15) 传感器(48,49,50,51)和用于根据头灯光轴的倾斜与前透镜表面(34)之间的固定关系来检测前灯光轴的装置,借助于测量头的输出( 9)。 根据本发明,前照灯需要进入,并且不需要大的空间来将头灯束投射到屏幕上。
