Abstract
The utility model discloses a vehicle wheel hub fastener. A bolt comprises a screw rod and a bolt head; the circumferential surface of a fixedly-connected section of the screw rod and the bolt head is provided with longitudinal stripes surrounding the entire circumference, the longitudinal stripes can form friction with the hole wall of a fixed hole when the bolt is inserted into the fixed hole of a wheel hub, so that the bolt is difficult to be pulled out from the fixed hole of the wheel hub and the mounting is easier; a gasket is equilateral-dodecagon shaped, one end thereof is matched with a nut along a semi concave circular groove inside a central hole, and the other end thereof is a flange radially extending outwards along the central hole; the nut comprises a threaded connection part and a guide part, one end of the guide part is movably sheathed on the threaded connection part, and a flange of an outer edge of the guide part is matched with the gasket; and when the bolt and the nut are screwed tightly, the gasket and the nut can play the roles of guiding the wheel hub and protecting the wheel rim.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly relates to a kind of automobile-used wheel hub fastening piece.
Background technique
The wheel hub of truck with realize being connected by bolt 1 ' and nut 2 ' (shown in Figure 1A) between the steel ring.For the convenience of installing and fastening after stability, generally all be provided with stability plane 12 ' (shown in Figure 1B) on the side of bolt 1 ' head 11 ', cylindrical bolt head 11 ' is vertically cut a part of circular arc, form parallel breach (shown in Fig. 1 C), the stabilising surface of this stability plane 12 ' and wheel hub 10 ' lean (shown in Fig. 1 D) during installation, can prevent that bolt 1 ' rotates thereupon in the process of fastening nut 2 ', fastening back is difficult for loosening, but the stability plane 12 ' of this bolt head 11 ' portion is too little with wheel hub 10 ' the contacted area, the stabilising surface (dotted portion among the figure) of wheel hub 10 ' can cut in bolt head 11 ' portion in the process of fastening nut 2 ', thereby cause bolt 1 ' loosening rotation in wheel hub 10 ' hole, bolt 1 ' after loosening very easily is cut off under the situation of alternate load, thereby causes wheel hub 10 ' bolt short 1 ' working life, wheel hub 10 ' scrappage height.
The model utility content
The purpose of this utility model is to provide a kind of difficult drop-off, good, the easy automobile-used wheel hub fastening piece of assembling of tightness.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of automobile-used wheel hub fastening piece, and it comprises bolt, packing ring and nut, and gasket sleeve is connected on the bolt, and bolt is screwed onto in the screw of nut central authorities; Described bolt comprises screw rod and bolt head, and an end of screw rod is fixed in the middle part of bolt head, and the first side of bolt is the stabilising surface that cooperates with wheel hub.Described nut is made up of spiro union portion and guide portion; The central authorities of described spiro union portion have tapped hole and cooperate with the outside thread of screw rod, and the one end is provided with annular flange flange, and this annular flange flange activity is nested with in the annular groove of guide portion; The end face of one end of described guide portion is provided with the evagination sphere that cooperates with packing ring semi-circle annular groove, and this evagination sphere cooperates with packing ring semi-circle annular groove sphere; On guide portion, be provided with pilot hole and spacing hole that two ends connect mutually; Annular flange flange on the described spiro union portion is rotating to be nested with in spacing hole, contracts in the aperture ora terminalis of spacing hole, forms confined planes, make guide portion relatively spiro union portion radially can from spacing hole, not deviate from axial float.
The utility model offers the longitudinal stripe around full week on affixed section circumferential surface of screw rod and bolt head.
The top of described bolt head is trapezoid shaped, and the stabilising surface that the bottom cooperates with wheel hub is an arc surface.
Described packing ring profile is a polygonal, and a port in hole is outwards expansion radially, forms a hemisphere annular groove, and the other end of mesopore axially extends outward an annular flange flange along the mesopore hole wall.
After adopting such scheme, the utlity model has following advantage:
1, because the utility model bolt offers the longitudinal stripe around full week on affixed section circumferential surface of screw rod and bolt head, when this longitudinal stripe inserts the wheel hub fixed hole at bolt, meeting and fixedly hole wall formation friction, and be not easy from the wheel hub fixed hole, to deviate from, installation is more prone to.
2, because the packing ring profile is positive 12 square, and an end is along mesopore indent semi-circular groove, and the flange that the other end extends radially outward along mesopore with cooperating of nut, plays firm wheel hub, increase the load of bolt.
3, form by spiro union portion and guide portion owing to nut of the present utility model; one end of guide portion is actively socketed on the spiro union portion; the outer edge bead of guide portion and packing ring pairing, when bolts and nuts screwed, packing ring and nut can be with the effects of wheel hub correcting and protection steel ring.
4, because the stabilising surface that the utility model bolt head bottom cooperates with wheel hub is an arc surface, increased the length of stabilising surface and wheel hub cambered surface, be that area of contact increases, be not easy after the bolton to get loose, the cambered surface of the stabilising surface of arc and wheel hub is more identical simultaneously, can not damage the wheel hub fixed hole because of the rotation of bolt.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
