For achieving the above object, the utility model adopts following technological scheme:
A kind of automobile nut comprises nut body and nut, and the centre is made as penetration hole, and described nut body has outer wall and an inner threaded surface that tilts, and the centre is interior threaded hole; The joint of described nut body and nut is symmetrically arranged with respectively four stiffening ribs.
Further, described nut is the eight-sided formation of four long legs and four short leg alternative arrangements.
Further, described stiffening rib is triangular prism structure, and one side is connected to the outer wall of nut body, and another side is connected to the inner face of nut, and its end extends to the neutral position of the short leg of this nut.
Further, the neutral position of four long legs of described nut extends to form four lug bosses, and the other end of described lug boss is connected to the outer wall of described nut body.
Further, the angle of inclination of described internal thread is 12 ° ~ 17 °.
Further, the angle of inclination of described internal thread is 15 °.
Further, described nut is 84mm ~ 92mm along the axial length of interior threaded hole; The length of described long leg is 45mm ~ 63mm; The width of described stiffening rib is 4mm ~ 8mm.
Further, the axial length of described nut is 52mm ~ 70mm; The external diameter of described nut is 52mm ~ 58mm.
Further, the outer wall of described nut is provided with the anti-corrosive primer layer.
Further, the diameter of described interior threaded hole is 44mm.
Compared with prior art, the beneficial effects of the utility model are:
1, the joint of nut body of the present utility model and nut is arranged with four stiffening ribs, when assembling with component, is difficult for looseningly, plays firm effect;
2, in addition, the internal surface neutral position of nut extends internally and is formed with four symmetrically arranged lug bosses, and its other end is connected to the nut body surface;
3, the utility model adopts specific size, better cooperates with other component;
4, adopt the anti-corrosive primer layer, prevent that nut from getting rusty, increase the service life, reduce the rate of fault of car load, avoid potential safety hazard;
5, adopt spheroidal graphite cast iron to make through integral forming process, manufacture simply, manufacturing efficiency is high, and output is large.
