An automobile trailing arm for testing comprises a main plate, one end of the main plate is provided with a mounting hole used for connecting a wheel support rack, the other end of the main plate is provided with a connecting hole used for connecting a fixing seat, a circular ring supporting disc is fixed around the connecting hole, a bearing seat penetrates through the connecting hole and the supporting disc, a knuckle bearing is arranged in the bearing seat, and the knuckle bearing rotates around a fixing seat bolt. The device can simulate the motion state of a rubber bushing, is simple in structure, is convenient to operate, can replace an original trailing arm in a test process, and can guarantee that the spatial position of a wheel support is consistent with the spatial position in a real vehicle. 一种试验用汽车拖曳臂，包括主板，主板一端设有用于连接车轮支架台架的安装孔，另一端设有用于连接固定座的连接孔，连接孔周围固定圆环支撑盘，轴承座穿过连接孔与支撑盘，轴承座内置有关节轴承，关节轴承绕固定座螺栓转动，可以模拟橡胶衬套运动状态，本实用新型结构简单，便于操作，能够在试验过程中对原厂拖曳臂进行代替，且能保证车轮支架的空间位置与实车中的空间位置一致。
