Use restrain board's combined material the wheel connection structure

The utility model provides an use restrain board's combined material the wheel connection structure, comprises upper and lower two restrain board, the preprocessing has bolt hole and centre bore respectively on upper and lower restrain board to this guarantees wheel bolt hole position degree and wheel centre hole size precision, upper and lower restrain board presets in wheel injection mold before combined material wheel injection moulding, and in order to improve metal restrain board and the partial joint strength of compound material, upper and lower restrain board does surperficial annular knurl with combined material the contact region and handles, among the wheel injection molding process this upper and lower restrain board under injection pressure with wheel combined material part zonulae occludens. These upper and lower two combined material the wheel connection structures that restrain board constitutes improve the intensity of being connected the face with compound material effectively. The combined
