Rubber ball hinge bidirectional loading fatigue test device

The utility model relates to a two-direction loading fatigue test machine for a rubber bushing. The device comprises at least one radial force applying device which is vertically contacted with a tested rubber bushing and applies a radical test force to the tested rubber bushing; and at least one deflecting force applying device which is contacted with the tested rubber bushing through a deflection cover and applies a deflection test force to the tested rubber bushing. The radial force applying device is a hydraulic force applying device with a guiding device, and the deflecting force applying device is a rotation force applying device. The radial force applying device, the deflecting force applying device and the guiding device together fulfill the two-direction loading fatigue test for a tested rubber bushing from a radical direction and a deflecting direction, and the directions of radical loading and deflecting torque are vertical to each other.
