Description

A kind of wheel nut

Technical field

The utility model wheel parts technical field, is more particularly to a kind of wheel nut.

Background technique

It after tire is installed in vehicle bridge, need to be attached with wheel bolt and wheel nut, wheel bolt is in driving vehicle bridge Assembling process in be typically all to assemble in advance, wheel nut screwed in wheel spiral shell after bead seat is passed through wheel bolt It is fastenedly connected on bolt.It is higher to the connection request of bolt and nut due to the high speed rotation of tire in running car, Biggish length of thread engagement has usually been required, but due to vehicle and has been applicable in the difference of tire in practice, so that when wheel When tire wheel rim enlarged in thickness, the screw thread exposed length of wheel bolt will be reduced, and then wheel bolt and wheel nut screw length Degree will also be reduced therewith, be caused the bonding strength between wheel bolt and wheel nut to substantially reduce, be made to the high-speed cruising of vehicle At huge security risk.And wheel nut in the prior art can not prevent the objects such as rainwater, silt from entering to wheel spiral shell In bolt, to will cause the corrosion of wheel bolt, or even the damage of bolt screw thread is caused.These defects serious limit values wheel The generalization of bolt develops, and causes challenge for the firm installation of wheel.

Summary of the invention

The purpose of this utility model is to provide a kind of automobile nuts, have solved the problems mentioned above in the background art.

The utility model is the technical solution realizing the purpose and taking are as follows: a kind of wheel nut, including nut body, Nut collar and nut cap, the nut body have the ut socket lengthened, and the nut collar is sheathed on the nut sheet The periphery of body, wherein the inside of the nut body forms cylindrical hole structure transparent back and forth, on the inner wall of cylindrical hole The internal screw thread that can be threadedly coupled with wheel bolt is formed, is formed with targeting port, internal screw thread tooth bottom in one end of cylindrical hole Place is equipped with a tapered ramp, and the angle between the tapered ramp and the internal screw thread lower plane reverse extending line is 30 °, institute Stating nut cap includes a column lid, and the lid is set in outside the nut body, and the lid is equipped with for being arranged nut The cavity of ontology, described lid one end are equipped with the masking face that can cover the cavity, and the inner wall of the lid is equipped with and can increase The increasing for covering internal wall friction power rubs structure, and increasing structure of rubbing is several raised lines being connected on lid, on the outside of the lid Face is equipped with annular groove.

Further, the internal diameter of the pilot hole is greater than the internal diameter of cylindrical hole.

Further, the raised line is arranged along the axial direction of lid.

Further, the raised line is parallel to each other two-by-two.

Compared with prior art, the utility model has the beneficial effects that by the way that long set is arranged on original wheel nut Cylinder, when solving hub for vehicle wheel enlarged in thickness, bolts and nuts screwing length reduces brought wheel installation strength problem, real Show and the high-strength bolt of tire has been threadedly coupled under the premise of bead seat any thickness, by adding one in interior Bottom of Thread A 30 ° of tapered ramp, when bolts and nuts are mutually tightened, the cusp of bolt just tightly withstands on variable-tooth type checknut On tapered ramp, so that very big coupling mechanism force is produced, it, can be by lid using the raised line by the way that raised line is arranged on lid inner wall It is firmly set on nut body, so that lid be made easily not split away off from nut, prevents nut in extraneous item It gets rusty under the influence of part.

Fig. 2 is the structural schematic diagram of the utility model lid.

Fig. 3 is the structural schematic diagram of the utility model screw thread.

Specific embodiment

Specific embodiment of the present utility model is made a detailed explanation with reference to the accompanying drawing.

As shown in Figure 1-Figure 3, a kind of wheel nut, including nut body 1, nut collar 2 and nut cap, the nut sheet Body 1 has the ut socket 4 lengthened, and the nut collar 2 is sheathed on the periphery of the nut body 1, wherein the nut sheet The inside of body 1 forms cylindrical hole structure transparent back and forth, and spiral shell can be carried out with wheel bolt by being formed on the inner wall of cylindrical hole The internal screw thread 5 of line connection, is formed with targeting port 11 in one end of cylindrical hole, is grown by being arranged on original wheel nut Sleeve 4, when solving hub for vehicle wheel enlarged in thickness, bolts and nuts screwing length reduces brought wheel installation strength and asks Topic is realized and is threadedly coupled under the premise of bead seat any thickness to the high-strength bolt of tire, and 5 tooth bottom of internal screw thread is equipped with One tapered ramp 6, the angle between 5 lower plane reverse extending line of the tapered ramp 6 and the internal screw thread be 30 ° by One 30 ° of tapered ramp 6 is added at 5 tooth bottom of internal screw thread, and when bolts and nuts are mutually tightened, the cusp of bolt is just tightly pushed up On the tapered ramp 6 of variable-tooth type checknut, so that very big coupling mechanism force is produced,

As shown in Fig. 2, the nut cap includes a column lid 3, the lid 3 is set in outside the nut body 1, institute Lid 3 is stated equipped with the cavity 7 for being arranged nut body 1, described 3 one end of lid is equipped with the masking that can cover the cavity 7 Face 8, the inner wall of the lid 3, which is equipped with, can increase the increasing of 1 inner wall frictional force of lid and rubs structure, and increasing structure of rubbing is to be connected in Lid 3 and nut body 1 can be carried out interference fit by the raised line 9, so that lid 3 by several raised lines 9 on lid It will not easily fall off.The lid lateral surface is equipped with annular groove 10.

Further, the internal diameter of the targeting port 11 is greater than the internal diameter of cylindrical hole.

Further, the raised line 9 is arranged along the axial direction of lid.

Further, the raised line 9 is parallel to each other two-by-two.
