The utility model discloses a kind of wheel nut assembly in auto parts and components field, in order to solve the secondary easy-to-rust of wheel connecting thread, damage, fracture, loosen etc. problem, solution comprises nut body, described nut body lower end is socketed in cavity that pad is offered, on the ring-shaped step that the cavity bottom being positioned at pad is arranged, device has a ring elastic parts, described pad and nut body lower end are that the barb that arranges of the socket place, upper end by being arranged on annular boss on nut body lower end outside wall and pad is along limit pivot bush unit, be positioned at end, described nut body upper end and be provided with blanking cover.The utility model beneficial effect be solve bolt thread exposed parts in regular screw threads auxiliary structure can not corrosion and the problem damaged of colliding with, the increase of disc spring significantly improves the self-locking performance of screw pair, anti-loosing effect increases, and solves the long-standing problem disconnected a pine of wheel bolt.

Description

A kind of wheel nut assembly

Technical field

The utility model relates to technical field of automobile parts, is specifically related to a kind of wheel nut assembly.

Background technique

In view of vehicle can travel on the road surface of different road conditions, the bolt thread installed in the screw pair of fixing vehicle wheel can be caused to leak outside part meeting corrosion or/and damage of colliding with, make nut cannot dismantle or destroy screw pair in unloading process, moreover be exactly that the self-locking property of the known screw pair for installing fixing vehicle wheel at present also needs further raising, connect and loosen and can make bolt fracture, bring danger in driving conditions.

Model utility content

For the deficiencies in the prior art, the utility model provides a kind of wheel nut assembly.

To achieve these goals, the utility model solves the technological scheme that its technical problem adopts: a kind of wheel nut assembly, comprise nut body, described nut body lower end is socketed in cavity that pad is offered, on the ring-shaped step that the cavity bottom being positioned at pad is arranged, device has a ring elastic parts, described pad and nut body lower end be the barb that arranges of the socket place, upper end by being arranged on annular boss on nut body lower end outside wall and pad along limit pivot bush unit, be positioned at end, described nut body upper end and be provided with blanking cover.

Furtherly, described ring elastic parts is disc spring, and a side of disc spring contacts with nut body lower end surface, and the another side of disc spring contacts with the table top of ring-shaped step, and the diameter of disc spring is less than the diameter of pad cavity.

Furtherly, the edge of the lower end surface through hole of described pad is provided with annular projection edge, the madial wall at annular projection edge and the through-hole wall of pad are integral type inwall, and the outer side wall at annular projection edge is the conical surface, and conical surface diameter increases gradually from outside oral area to the end face outside of pad; Described barb is connected along between limit and the outer wall of pad by conical surface transition.

Furtherly, described blanking cover is cylindrical blanking cover, in the counterbore that the upper end end face that cylindrical blanking cover is fixed clamping or is welded on nut body is offered or shoulder hole.

The beneficial effects of the utility model: the utility model solves bolt thread exposed parts in regular screw threads auxiliary structure can not corrosion and the problem damaged of colliding with, the increase of disc spring significantly improves the self-locking performance of screw pair, anti-loosing effect increases, and solves the long-standing problem disconnected a pine of wheel bolt.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the plan structure schematic diagram of Fig. 1.

Embodiment

Below in conjunction with specific embodiment, the utility model is described in further detail,

A kind of wheel nut assembly as depicted in figs. 1 and 2, comprise nut body 1, described nut body 1 lower end is socketed in cavity that pad 2 is offered, on the ring-shaped step that the cavity bottom being positioned at pad 2 is arranged, device has a ring elastic parts 5, described pad 2 and nut body 1 lower end be the barb that arranges of the socket place, upper end by being arranged on annular boss 3 on nut body 1 lower end outside wall and pad 2 along limit 7 pivot bush unit, be positioned at end, described nut body 1 upper end and be provided with blanking cover 4.

Preferably, described ring elastic parts 5 is disc spring, and a side of disc spring contacts with nut body 1 lower end surface, and the another side of disc spring contacts with the table top of ring-shaped step, and the diameter of disc spring is less than the diameter of pad 2 cavity.(when the spring washer of standard or disc spring application are with screw pair, all use Split type structure, but because the installing space of boss bolt is limited, traditional spring ring or disc spring cannot be used, disc spring or spring washer are embedded between nut and pad, make it integrally be convenient to assembling and control, also can realize relaxation effect simultaneously.)

Preferably, the edge of the lower end surface through hole 8 of described pad 2 is provided with annular projection edge 6, the madial wall at annular projection edge 6 and the through-hole wall of pad 2 are integral type inwall, the outer side wall at annular projection edge 6 is the conical surface, and conical surface diameter increases gradually from outside oral area to the end face outside of pad 2; Described barb is connected along between limit 7 with the outer wall of pad 2 by conical surface transition.

Preferably, described blanking cover 4 is cylindrical blanking cover, in the counterbore that the upper end end face that cylindrical blanking cover is fixed clamping or is welded on nut body 1 is offered or shoulder hole.

To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.

In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
