    • A roller-type ultrasonic inspection device for inspecting vehicle tires comprises a roller assembly 20 mounted on a non-rotatable hug 16. Two piezoelectric crystals 80,82 are mounted in the hub 16 such that their principal transmitting/receiving axes A and B converge generally radially outwardly of the hub. The angle between the axes A and B is selected such that when the roller assembly 20 is urged into rolling contact with the tread-bearing surface of a tire 90, the axes meet (allowing for refraction effects) in the body of the tire beneath the tread. This ensures that the device can detect defects in the body of the tire, and is relatively insensitive to the tread.
    • 用于检查车辆轮胎的辊式超声波检查装置包括安装在不可旋转的保持器16上的辊组件20.两个压电晶体80,82安装在毂16中,使得它们的主要发送/接收轴线A和B一般收敛 轮毂径向向外。 选择轴A和B之间的角度,使得当辊组件20被推动与轮胎90的胎面承载表面滚动接触时,轴线在轮胎下方的轮胎本体内相遇(允许折射效应) 踏。 这确保了该装置能够检测轮胎体内的缺陷,并且对胎面相对不敏感。
