Abstract
The utility model discloses a take novel wheel nut assembly of protection casing, it includes wheel nut and wheel protection casing, the wheel protection casing divide into circular cylinder part and spherical top surface part, circular cylinder part and spherical top surface part structure as an organic whole, the outer tip of the face of cylinder on wheel nut top is equipped with recessed step face, the circular cylinder part and the recessed step face interference fit of wheel protection casing, the interior terminal surface of recessed step face is the inclined plane. The utility model discloses not only have the function of original wheel nut assembly of taking the protection casing, its simple structure is firm moreover, and non-deformable drops, more has sealing performance, and reducible part material's waste has very big use value.
Description
Technical field
The utility model relates to technical field of automobile parts, refers to particularly a kind of with protecting cover wheel nut assembly.
Background technique
The screw thread of wheel nut in the Vehicle Driving Cycle process is because the infringement of mud, sand, water etc., and wheel evagination thing wedge angle all needs to install additional the wheel nut cover to may the injuring of people, thing on the general wheel nut.The scheme that at present installs the wheel nut cover additional at wheel nut is split type, wheel nut assembly as shown in Figure 1, namely consisted of by wheel nut cover 2 and wheel nut 1 two-part, wheel nut cover 2 is assemblied on the wheel nut 1, design is prone to coming off, being out of shape of wheel nut cover like this, and then can cause the waste of part material.
In the Patent Application Publication of CN201120116651.9, a kind of nut cover is disclosed, it comprises nut cover and hexagon nut, nut cover and hexagon nut are slidingly connected, and the rivet hole by being provided with in nut cover, adopt the means of fixation of bolt that nut cover and hexagon nut are fixed, main purpose is the easy installation and removal that makes between nut cover and the nut, this scheme can not solve coming off, being out of shape of wheel nut cover, and then can cause the phenomenon of the waste of part material.Therefore, need existing with protecting cover wheel nut assembly is improved.
The model utility content
The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, provides a kind of simple in structure firm, the not yielding with protecting cover wheel nut assembly that comes off of protective housing.
The technical solution of the utility model is: a kind of with protecting cover wheel nut assembly, comprise wheel nut and wheel protection cover, described wheel protection cover is divided into circular cylinder body part and dome face portion, circular cylinder body part and dome face portion are structure as a whole, the outer end of the cylndrical surface on described wheel nut top is provided with the recessed ledge frame face, circular cylinder body part and the recessed ledge frame face interference fit of wheel protection cover, the interior edge face of recessed ledge frame face is the inclined-plane.
In such scheme: the angle between the interior edge face of described recessed ledge frame face and the wheel nut axis is greater than the angle between the axis of the exterior edge face of circular cylinder body part and wheel protection cover, it is that line contacts that the exterior edge face that can guarantee like this interior edge face of recessed ledge frame face and circular cylinder body part press-fits after contact, can guarantee the sealability of the interference fit of wheel nut and wheel protection cover.
Described wheel protection cover diameter is less than the opposite side back gauge of wheel nut, can guarantee so unlikely damage wheel protection cover in the nut assembly installation process.
The dome face portion of described wheel protection cover and circular cylinder body part outer surface are seamlessly transitted by knuckle, can effectively avoid like this wheel evagination thing to the injury of people, thing.
The utility model is connected the mode of interference fit to connect wheel nut with wheel protection cover, the function that not only has original with protecting cover wheel nut assembly, and it is simple in structure, firmly, yielding coming off not, have more sealability, can reduce the waste of part material, have very large use value.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the utility model, but they do not consist of restriction to the utility model.
Such as Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, a kind of with protecting cover wheel nut assembly, comprise wheel nut 1 and wheel protection cover 2, wheel protection cover 2 is divided into circular cylinder body part 2.2 and dome face portion 2.1, circular cylinder body part 2.2 and dome face portion 2.1 are structure as a whole, the outer end of the cylndrical surface 1.1 on described wheel nut 1 top is provided with recessed ledge frame face 1.2, circular cylinder body part 2.2 and recessed ledge frame face 1.2 interference fit of wheel protection cover 2, the interior edge face 1.3 of recessed ledge frame face 1.2 is the inclined-plane.Angle between the interior edge face 1.3 of described recessed ledge frame face 1.2 and wheel nut 1 axis is greater than the angle between the axis of the exterior edge face 2.4 of circular cylinder body part 2.2 and wheel protection cover 2, the exterior edge face 2.4 that can guarantee like this interior edge face 1.3 of recessed ledge frame face 1.2 and circular cylinder body part 2.2 press-fit contact after for line contacts, can guarantee the sealability of the interference fit of wheel nut 1 and wheel protection cover 2.Wheel protection cover 2 diameters are less than wheel nut 1 opposite side s back gauge in the present embodiment, can guarantee so unlikely damage wheel protection cover in the nut assembly installation process; And the design that the dome face portion 2.1 of wheel protection cover 2 and circular cylinder body part 2.2 outer surfaces are seamlessly transitted by knuckle 2.3, cocoa effectively avoids wheel evagination thing to the injury of people, thing.
It is simple in structure, firm that present embodiment has, and difficult drop-off is out of shape, and has more the characteristics of sealability, can effectively reduce the waste of part material, has very large use value.
