Description

Self-centering locknut for wheel

Technical Field

The utility model relates to the technical field of automotive fasteners, in particular to a self-centering locknut for an automotive wheel.

Background

The wheel locknut is a common fastener in an automobile, the wheel nut is a special nut for fixing an automobile hub, and because of uncertainty of the shape and the size of the wheel nut, the wheel nut does not have a national standard, but the general model is approximately the same as that of a common hexagon nut, and is also various models in the middle of M12-M42. Compared with the common hexagonal nut, the wheel nut is generally thicker than a hexagonal national standard nut with the same specification, has fine teeth, has thread pitch of approximately 1.5 mm and 2.0 mm, and is in an equilateral hexagon in the same shape as the hexagonal nut.

In the field of vehicle engineering, the wheel hub and the wheel rim of an automobile are connected through bolts and corresponding wheel nuts, and the automobile wheel nuts serve as a part of an automobile hub assembly and play a vital role in the advancing process of the automobile.

At present, three types of wheel nuts are commonly used in the market, one type is a ball nut, the ball nut has the advantages that the contact surface of the nut and a hub can be effectively increased through a spherical flange, the nut and a bolt can generate larger torsion and loading force, the defect is that the contact surface of the spherical nut and a rim is smaller, the nut is easy to loosen and even fall off when the connecting structure is subjected to larger vibration, the loosening and falling phenomena are more prominent, once the nut is loosened, parts which need to be fastened and connected together originally can be separated, and serious potential safety hazards exist for the driving of a vehicle; the other type is a conical surface nut, which has the advantages that the taper of the conical surface nut can be better attached to the inside of a hub hole, and a hub bolt and a rim mounting hole keep coaxial, and has the defect that the thread buckling position is the most pointed part of the conical surface and is easily extruded and deformed by the rim to influence the use; the other type is a cushion connecting nut, which has the advantages that the wide flange at one end distributes the pressure of the nut on the rim mounting surface, the possibility of the rim being crushed is reduced, the contact area is increased, so that the cushion connecting nut has the anti-loosening function, and the defect that the function of keeping the hub bolt and the rim mounting hole coaxial is not realized.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects, the technical problems to be solved by the utility model are as follows: the utility model provides a wheel is from centering locknut to the easy not hard up problem appears in the use of preventing the wheel nut, can keep hub bolt and rim mounting hole coaxial moreover.

In order to solve the technical problems, the technical scheme of the utility model is as follows:

the utility model provides a wheel is from centering locknut, includes the nut body, be provided with the ring flange on the terminal surface of nut body, the ring flange rotates to be connected on the nut body, the nut body is close to one side of ring flange is provided with a screw thread section of thick bamboo.

Preferably, the internal thread of the thread cylinder and the internal thread of the nut body are coaxially arranged and have the same hole diameter.

Preferably, the nut body is provided with a spherical protrusion, and the flange plate is provided with a spherical groove matched with the spherical protrusion.

Preferably, the radial dimension of the flange is greater than the radial dimension of the nut body.

Preferably, the nut body is integrally provided with the threaded cylinder.

Preferably, the nut body is a hexagonal nut.

After the technical scheme is adopted, the utility model has the beneficial effects that:

1. the flange plate is rotatably connected to the nut body, so that the contact area between the self-centering locknut of the wheel and a rim is increased, and the locknut has a locking function;

2. the nut body is provided with the screw thread section of thick bamboo of an organic whole setting, and the screw thread closes length soon and is longer than conventional nut, has improved threaded connection's reliability, and the screw thread section of thick bamboo that has length can stretch into in the rim mounting hole, can keep hub bolt and rim mounting hole coaxial, does not receive the rim extrusion after the fastening, and the screw thread can not warp, and the result of use is better.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in fig. 1-6 together, a wheel self-centering locknut comprises a nut body 1, a flange plate 2 is arranged on the end face of the nut body 1, the flange plate 2 is rotatably connected to the nut body 1, the nut body 1 can be rotatably provided with a connecting structure of the flange plate 2, so as to prevent friction between the nut and a rim 4 generated by rotation of the nut during installation or disassembly, a threaded cylinder 3 is arranged on one side of the nut body 1 close to the flange plate 2, the internal thread of the threaded cylinder 3 is coaxially arranged with the internal thread of the nut body 1, and has the same aperture, so that a hub bolt 7 can be conveniently installed, the threaded cylinder 3 is provided with a corresponding length according to the thickness of a hub under actual wheel installation conditions, the threaded cylinder 3 with the length can extend into an installation hole of the rim 4, the fastening is not extruded by the rim 4, the threads cannot deform, and the hub bolt 7 and the rim installation hole can be kept coaxial.
