    • Disclosed is a gasbag type pavement testing apparatus, comprising a main frame (7), roller wheels (1) and a pneumatic suspension frame system which consists of gasbags (2), ventilated bolts (5), spokes (6), an inflating valve (10), a communicating shaft (11) and rockers (3). The gasbags (2), ventilated bolts (5), spokes (6), inflating valve (10), and communicating shaft (11) constitute an air storing space interconnecting each gasbag, the air storing space is inflated or deflated through the inflating valve (10), and the rockers (3) are hinge-jointed with the spokes (6). The spokes (6), rockers (3) and the communicating shaft (11) constitute a spoke assembly. The roller wheels (1) are driven by the spoke assembly to rotate round the communicating shaft (11), the roller wheels (1) contact the pavement in turn under the joint action of the gasbags (2) and the spoke assembly to simulate the practical situation and hence conduct the rolling test for the pavement. The testing apparatus performs the test with higher accuracy and higher efficiency.
    • 公开了一种气囊式路面试验装置,包括主框架(7),滚轮(1)和气囊悬挂框架系统,其由气囊(2),通风螺栓(5),辐条(6),膨胀阀 (10),连通轴(11)和摇臂(3)。 气囊(2),通气螺栓(5),辐条(6),充气阀(10)和连通轴(11)构成一个将每个气囊相互连接的空气存储空间,空气存储空间通过充气阀膨胀或放气 (10),摇臂(3)与轮辐(6)铰接。 辐条(6),摇臂(3)和连通轴(11)构成一个辐条组件。 滚轮(1)由轮辐组件驱动以围绕连通轴(11)旋转,滚轮(1)在气囊(2)和轮辐组件的联合作用下依次接触路面,以模拟 实际情况,进行路面滚动试验。 测试装置以更高的精度和更高的效率进行测试。
