Because the bearing assembly is arranged on the inner wall of the ring of the half ring, the upper pipe column is rotatably connected with the half ring in the mode, the normal operation of a steering system is not influenced, the structure of the original cantilever beam is changed through the addition of the connecting rod, the frequency of the steering system is changed, and the shaking of the steering wheel in the idling process can be avoided.
The further technical proposal is that the diameter of the steering wheel framework is between 330 and 600 mm. The diameter value of the steering wheel skeleton is set by considering the shoulder width and avoiding the aching of shoulder muscles caused by long-time driving.
The further technical proposal is that the spoke at most comprises two spoke segments with different curvatures which are connected end to end along the axial direction of the middle shaft. The arc connecting section is reduced, the generation of stress concentration can be reduced, and the strength and the impact resistance of the steering wheel are enhanced.
The utility model has the advantages and beneficial effects that: the original structure that the upper pipe column is longer and forms a cantilever beam is changed, resonance caused by the fact that a steering system is close to the idling frequency of an engine when idling can be avoided, and shaking is reduced; the four spokes are arranged on the steering wheel at least, the impact resistance is enhanced, the stress concentration is not easy to occur, the strength of the steering wheel is enhanced, under the action of axial force and impact load, the permanent deformation of the four-spoke steering wheel framework is found to be 5.13mm, the test deformation of a steering wheel material object is found to be 8.35mm, and the phenomena of cracks and damage do not occur.
