Abstract
The utility model relates to a fixing bolt of an anti-abrasion automobile wheel. The fixing bolt comprises a bolt body, wherein one side of the bolt body is provided with a hexagon nut; the other side of the bolt body is provided with a stud body with a thread; the middle part of the bolt body is provided with a connecting body; an annular groove is arranged at the connecting body part; an anti-abrasion blocking sheet is arranged inside the annular groove; the anti-abrasion blocking sheet is in an annular sheet shape; an annular plane at one side of the anti-abrasion blocking sheet is of an inner concave tapered plane; another annular plane at the other side of the anti-abrasion blocking sheet is of an outer convex tapered plane; and the outer convex tapered plane of the anti-abrasion blocking sheet is arranged beside the stud body of the bolt body. Taper angles alpha of the two side tapered planes of the anti-abrasion blocking sheet are identical. The fixing bolt is reasonable in design and simple in structure, and has a respectively wide application range.
Description
Technical field
The utility model belongs to automotive wheel tightening technology field, is specifically related to a kind of anti-wear automotive wheel fixing bolt.
Background technique
In the AE field, Wheel set bolt has important effect.The wheel clamping bolt is fixed on wheel on the vehicle hub bearing through being threaded; Be used for support vehicle and wait the weight under all operating modes in static and motion; The wheel clamping bolt belongs to outside visible parts simultaneously, and outward appearance is had higher requirement, adopts surperficial brightening treatment process usually.At present, what Wheel set bolt adopted is bolt and wheel rim conical surface compression fit, tighten with unloading process in; The bolt conical surface and the wheel rim conical surface trackslip relatively, and because of the aluminium rim material is an aluminum alloy, hardness is higher; Occur easily scratching because of rubbing relatively; Corrosion appears in the long-time back bolt that uses, and influences fastening effect and bolt looseness possibly occur, possibly occur bolt when serious and get loose and cause traffic accident.
The model utility content
In order to solve after the existing wheel clamping bolt dismounting problem of corrosion easily, the present invention provides a kind of anti-wear Wheel set bolt of structure to reduce to corrode that improve.
The technological scheme that the utility model adopted is:
A kind of anti-wear automotive wheel fixing bolt comprises bolt body, and bolt body one side is a hexagon nut; Opposite side is threaded spiro column; The middle part is columniform connecting body, and improvement is: said connecting body position is provided with annular groove, is provided with anti-wear catch in the annular groove;
Said anti-wear catch is an annular slice, and a side ring surface of anti-wear catch is the indent conical surface, and the opposite side ring surface is the evagination conical surface, and the evagination conical surface of said anti-wear catch is corresponding with the spiro column of bolt body.
The tapering α of the both sides conical surface of said anti-wear catch is identical, is 5 °-10 °.Best tapering α is 8 °; Adopt stainless steel material.
The utility model is reasonable in design, and is simple in structure.1, anti-wear catch adopts stainless steel material to avoid the fixing bolt attachment face corrosion to occur because of the wearing and tearing of trackslipping.2, applied widely: as can to adapt to the assembling of different vehicle through the adjustment of size.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is anti-wear baffle structure schematic representation.
Fig. 3 is the side view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done explanation further through embodiment.
Embodiment:
Referring to Fig. 1-Fig. 3, anti-wear Wheel set bolt comprises bolt body 1, anti-wear catch 2.Bolt body 1 one sides are hexagon nut; Opposite side is threaded spiro column, and the middle part is the connecting body of hexagon nut and spiro column, is provided with annular groove at the connecting body position; Recess width 5mm; The bolt body material can be selected No. 45 steel or SCM435 for use, and annular anti-wear catch 2 is an annular slice, selects stainless steel for use; One side end face indent conical surface, opposite side end face evagination conical surface; The evagination conical surface of anti-wear catch is positioned at the double-screw bolt side of bolt body.The aperture 17.1mm of anti-wear catch interior bone, external diameter 29mm, thickness 3mm, the tapering α of both sides conical surface is 8 °.Be fitted in the groove on the bolt body 1.
When fixing bolt is tightened; Fit in the crowning of anti-wear catch 2 and the mounting hole plane on the wheel rim; Concave face and hexagon nut interior edge face are fitted, and because of the surface of contact frictional force of anti-wear catch 2 both sides is different, anti-wear catch 2 rotates in company with bolt body 1 jointly; Anti-wear catch protruding end and wheel rim attachment face relatively rotate, and are tightened until bolt.Can effectively reduce the surface abrasion that bolt body 1 causes because of anti-wear catch 2 exists in disassembly process, reduce the corrosion of bolt body.
