Embodiment 1

[0024] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a split nut includes a nut shell and a nut inner core, a connection and cooperation structure is provided between the nut shell and the nut core, the connection and cooperation structure is a threaded connection, and the nut The material of the cap shell is an aluminum alloy material, and the material of the nut core is high-hardness alloy steel. The nut shell includes a nut shell head 3, a nut shell connecting arm 4 and a nut shell bottom 6. The nut shell head 3, the nut shell connecting arm 4 and the nut shell bottom 6 are integrally connected, and the nut core includes a nut core head 1, a nut core connecting part 2, a nut core The cap core connecting arm 14 and the nut core bottom 15 are integrally connected between the nut core head 1, the nut core connecting portion 2, the nut core connecting arm 14 and the nut core bottom 15 .

[0025] Such as figure 2 Shown, as a kind of preferred scheme of p...

Embodiment 2

[0032] The main feature of this embodiment 2 is: the thread pitches of the inner thread 10 of the inner core of the nut, the outer thread 12 of the inner core of the nut and the inner thread 13 of the outer shell of the nut are all 1.25mm. All the other features are the same as in Example 1.

[0033] In summary, a split nut designed by the present invention has simple structure, convenient use, and low cost. The nut shell and the nut core are connected by threads. The material of the nut shell is aluminum alloy. The inner core is made of high-hardness alloy steel. The aluminum alloy shell has various colors and styles to meet individual needs. The shell part can be replaced at any time according to individual needs, while the core part does not need to be replaced, saving resources. Hardness requirements, and can overcome the problem of single nut color, the present invention uses this split nut to fix the car wheel hub, uses high hardness alloy steel to make the nut core to e...

Abstract

The invention discloses a split-type screw cap, and belongs to the technical field of automobile parts. The split-type screw cap comprises a screw cap shell and a screw cap core. A connection matchingstructure is arranged between the screw cap shell and the screw cap core and is used for threaded connection. The screw cap shell is made from aluminum alloy. The screw cap core is made from high-hardness alloy steel. The screw cap shell comprises a screw cap shell head, a screw cap shell connecting arm and a screw cap shell bottom. The screw cap core comprises a screw cap core head, a screw capcore connecting part, a screw cap core connecting arm and a screw cap core bottom. A screw cap core internal thread is arranged on the wall of a screw cap core through hole. A screw cap core externalthread is arranged on the outer wall of the screw cap core bottom. A screw cap shell internal thread is arranged on the screw cap shell and is matched with the screw cap core external thread. The split-type screw cap is simple in structure and convenient to use, the hardness requirement of the screw cap can be met, and the problem of a single color of the screw cap can be solved.

Description

technical field [0001] The invention relates to an automobile hub nut, in particular to a split nut for fixing an automobile hub, and belongs to the technical field of automobile parts. Background technique [0002] At present, the hub nut is a special nut used to fix the outer hub of the car. Because of the uncertainty of the car nut, there is no national standard for the car nut, but the general model is roughly the same as the ordinary hexagonal nut, and there are also M12-M42 For the various models in the middle, compared with ordinary hexagonal nuts, hub nuts are generally thicker than hexagonal national standard nuts of the same specification, and generally have fine teeth, and the shape is equilateral hexagonal like the hexagonal nuts. , but there will be a taper at one end of the nut, some inside the taper will have a step for placing nylon washers for locking, some sides have no step, and some hub nuts have a taper at the tapered part. If there is a flange on the o...
