Abstract

It is a car wheel bearing analogue test load device, which comprises drive main axis 1 and test main axis 2, test bearing supportive structure, radial and axis load cylinder structure. The connection end between radial load oil cylinder and frame is fixed with a ball socket bearing 5. The connection end between the axis bearing load oil cylinder and frame is fixed with ball socket bearing 11. Its radial load oil cylinder down part is directly fixed with proportion decompression valve 21 and electromagnetism switch valve 20. Its axis load oil cylinder down part is directly fixed with proportion decompression valve 15 and electromagnetism 14.

Description

technical field [0001] The invention relates to the technical field of automobile hub bearing tests, and relates to a loading device for a simulation test of an automobile hub bearing unit. Background technique [0002] The known simulation testing machine of the automobile hub bearing unit is to drive the main shaft to rotate through the frequency conversion motor, and the loading is provided by the radial loading oil cylinder and the axial loading oil cylinder, and the front ends of these two oil cylinders are connected with the The test body is connected, and the rear end of the oil cylinder is fixed on the frame, or the middle swing type oil cylinder is connected with the frame; the proportional pressure reducing valve is used to adjust the hydraulic pressure, and the radial loading oil cylinder exerts radial tension on the hub bearing. The axially loaded oil cylinder applies an axial tension or pressure to the hub bearing in a direction perpendicular to the radially loa...
