Description
technical field [0001] The invention relates to a rotary bending test machine, in particular to a rotary bending test device for a rigidly fixed hub of a steering knuckle. Background technique [0002] The wheel hub of the automobile needs to be subjected to the wheel hub rotational bending test before use. At present, when the automotive wheel hub rotational bending test machine is used to test the wheel hub, the method adopted is: the hub is set in the bearing, and the bearing is installed in the bearing frame. The hub is fixed on the main shaft at the same time, and the main shaft is connected with the motor reducer through a universal joint. The radial and axial loading cylinders apply radial and axial forces to the main shaft respectively, so as to test the deformation of the hub. During the loading test, the temperature of the bearing is often too high, which seriously affects the accuracy of the test. It is necessary to cool the bearing with a water jacket, and the st...
