Abstract
Description
Technical Field
[0001] This utility model relates to the field of fastener technology, specifically to a wheel hub bolt. Background Technology
[0002] Most European cars use bolts to fasten wheel hubs, but different companies use different fixing methods. Mercedes-Benz, Volkswagen, and Audi use R-shaped arc holes to fix the wheel hubs, while BMW and Renault use tapered 60-degree holes. Many modification customers will replace the wheel hubs, and after replacing the R-shaped arc hole wheel hubs with tapered 60-degree hole wheels, the bolts must be replaced. However, through research, it was found that the existing technology with announcement number CN221569143U, although the pressure block and the rod body are movably connected, the pressure block is a separate structure, and the two pressure blocks are connected together by a connecting rod. At the same time, a sliding port is opened on the rod body to facilitate the movement of the connecting rod. It is not difficult to see that it has at least the problem of complex structure and high manufacturing difficulty. Utility Model Content
[0003] The purpose of this invention is to provide a wheel hub bolt to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a wheel hub bolt, comprising a screw assembly and a washer mounted on the screw assembly; the screw assembly includes a rod portion and a drive portion integrally formed with the rod portion, and a mounting seat is provided at the connection between the rod portion and the drive portion; the mounting seat is provided with a countersunk hole, and a push rod is provided in the countersunk hole, and one end of the push rod passes through the countersunk hole and connects with a groove provided on the washer to fix the washer on the rod portion.
[0005] As a preferred technical solution of this utility model: a driving rod is also provided in the countersunk hole, and the driving rod moves in the countersunk hole to cause the top rod to press against the groove.
[0006] As a preferred embodiment of this utility model: a spring is further provided inside the countersunk hole; wherein one end of the spring is in contact with the push rod, and the other end of the spring is in contact with the drive rod.
[0007] As a preferred technical solution of this utility model: the outer wall surface of the drive rod is adapted to the internal thread of the inner wall surface of the countersunk hole through the external thread.
[0008] As a preferred technical solution of this utility model: the end of the top rod facing the groove is spherical, and the groove is a spherical groove.
[0009] The beneficial effects of this utility model by adopting the above technical solution are as follows: by separating the push rod from the groove, the gasket and the rod body can be separated, thus solving the problem of having to replace the bolts after replacing the wheel hub; at the same time, when one side of the gasket is in contact with the drive part, the push rod moves in the countersunk hole to make one end of the push rod insert into the groove, thus limiting the gasket and preventing the gasket from falling off.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.
[0017] Please see Figure 1-5The present invention provides an embodiment of a wheel hub bolt, comprising a screw assembly 1 and a washer 2 mounted on the screw assembly 1; the screw assembly 1 includes a rod portion 11 and a drive portion 10 integrally formed with the rod portion 1, and a mounting seat 13 is provided at the connection between the rod portion 11 and the drive portion 10; the mounting seat 13 is provided with a countersunk hole 12, and a push rod 14 is provided in the countersunk hole 12, and one end of the push rod 14 passes through the countersunk hole 12 and connects with a groove 3 provided on the washer 2 to fix the washer 2 on the rod portion 11.
[0018] In summary, by separating the push rod 14 from the groove 3, the gasket 2 can be separated from the rod body 1, thus solving the problem of needing to replace bolts after replacing the wheel hub. In particular, while fixing the gasket 2, it can also greatly simplify the processing difficulty of the wheel hub bolts. At the same time, when one side of the gasket 2 is in contact with the drive part 10, the push rod 14 moves in the countersunk hole 12 to make one end of the push rod 14 insert into the groove 4, so that the push rod 14 can limit the gasket 2 to prevent the gasket 2 from falling off.
[0019] Specifically, since the outer wall of the drive rod 16 is connected to the inner wall of the countersunk hole 12 through the external thread, the movement of the push rod 14 can be achieved by rotating the drive rod 16. In addition, the use of threaded engagement can also prevent the push rod 14 from automatically loosening.
[0020] Furthermore, a drive rod 16 is provided within the countersunk hole 12, and the drive rod 16 moves within the countersunk hole 12 to cause the push rod 14 to abut against the groove 3. Based on this, the drive rod 16 can enhance the pushing force of the push rod 14, thereby further ensuring the abutment force against the gasket 2.
[0021] Meanwhile, since a spring 15 is also provided in the countersunk hole 12; wherein one end of the spring 15 is in contact with the push rod 14 and the other end of the spring 15 is in contact with the drive rod 16, when the gasket 2 needs to be removed, the gasket 2 is pried upward until the gasket 2 is separated from the groove 4, and the gasket 2 can be removed from the screw part 11.
[0022] Furthermore, since the end of the top rod 14 facing the groove 3 is spherical and the groove 3 is a spherical groove, the pad 2 can be easily and conveniently placed or removed.
[0023] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
