In order to achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides a specialized tool is disassembled to wheel hub bearing fixation nut which characterized in that: the torsion shaft is fixedly connected with the middle of the stressing shaft according to a cross structure, the handles are arranged at two ends of the stressing shaft, the lower portion of the torsion shaft is connected with the upper surface of the disc, a plurality of clamping columns are uniformly distributed and fixed on the periphery of the disc, and the heights of the clamping columns exceed those of the lower surface of the disc.

Further preferably, the torsion shaft and the disc are arranged coaxially.

Further preferably, the lower end of the torsion shaft is a hexagonal shaft head, and an inner hexagonal structure is arranged on the disc and matched with the hexagonal shaft head at the lower end of the torsion shaft.

Further preferably, a plurality of clamping column fixing positions are uniformly distributed on the periphery of the disc, and each clamping column fixing position is provided with a threaded hole.

Further preferably, the joint post includes upper portion stiff end and lower part joint end, the upper portion stiff end cooperatees with the fixed position of the joint post of disc border.

Further preferably, the lower clamping end of the clamping column has a plurality of diameter configurations.

Further preferably, the force application shaft, the torsion shaft, the disc and the clamping column are made of steel.

The utility model has the advantages that:

firstly, according to the structure, according to the shape, the geometric dimension and the required fastening force of the nut, the force application shaft, the torsion shaft, the disc and the clamping column are all made of steel materials so as to ensure that the special tool has enough strength, the special tool is designed and manufactured, when the special tool is used, an operator needs to simultaneously grip the handle with two hands, firstly, the corresponding clamping column is selected, and the clamping column is installed on the clamping column fixing position of the disc and is fixedly connected with the clamping column fixing position through threads; because the hub bearing fixation nuts of different manufacturers are different in size, the special tool can be directly used for disassembling the nuts of different sizes by replacing different clamping columns, and the functionality of the tool is improved. The operating personnel holds the handle region, aims at the big nut that will disassemble with the disc, makes six joint posts that the disc border is fixed correspond the quincuncial inslot of big nut respectively, along anticlockwise afterburning, rotatory several weeks back, can accomplish disassembling of big nut to shorten the man-hour of the big nut of pegging graft, realize the maintenance of quick replacement brake mirror surface oil blanket and wheel reduction gear. The special tool has a good using effect, solves the problem that the maintenance is not difficult to cause by the special tool, is convenient and quick, and improves the working efficiency.
