The invention provides mud
saline of wheel hub bearing of automobile and a general endurance test method. In the test method, a testing bearing is supported on a testing table in the cantilevered way; a loading shaft is used for driving the
coating of the testing wheel hub bearing to rotate at the same speed as the rotating speed in the actual working status; the
axial load and the radial load can be respectively or simultaneously exerted on the testing wheel hub bearing; the
axial load and the radial load, which are exerted by the testing wheel hub bearing, are exerted on the
coating of the testing wheel hub bearing which rotates at a high speed, through a
loading arm which is vertical to the loading axle, a loading sleeve which is fixedly linked with the
loading arm and arranged on the loading axle, a support
loading arm, and a pair of conical rollers; thus the
coating of the testing wheel hub bearing can rotate at a high speed and simultaneously is provided with the exerted
axial load and the radial load; a water spraying device is used for directly spraying the mud
saline to the testing wheel hub bearing (17) with the external load; a temperature sensor (18) is arranged on the non-rotating end face of the testing wheel hub bearing; and a
vibration sensor (19) is arranged in the position of the fillet of the testing wheel hub bearing.
