[0002] In the field of automotive manufacturing and parts technology, the steering knuckle, as a key component of the automotive steering system, plays a crucial role in the overall driving stability and safety of the vehicle. For example, the existing patent with publication number "CN201566694U" discloses "a novel steering knuckle locking device, characterized in that an outer bearing is provided at one end of the steering knuckle, a steering knuckle nut locking washer is provided on one side of the outer bearing, the steering knuckle nut locks the steering knuckle nut locking washer, and a cotter pin locks the steering knuckle nut." It can be seen that the application describes a common steering knuckle locking device. However, traditional steering knuckle locking devices have many problems in design and use. These problems not only affect assembly efficiency but also increase the difficulty of later maintenance and repair.

[0003] The existing steering knuckle shaft head locking mechanism mainly consists of three parts: a locking washer, a grooved locking nut, and a cotter pin. The nut is locked and the locking washer is prevented from rotating by cutting and drilling the threads of the steering knuckle shaft head. However, this existing locking method will damage the integrity of the shaft head threads, and the three parts need to be installed separately, which is not quick enough. Therefore, this utility model proposes a new steering knuckle shaft head locking device. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example

[0031] Please see Figures 1 to 11 This is an embodiment of the present utility model, which provides a technical solution: a novel steering knuckle head locking device, comprising...

[0032] The lock nut 11, the nut disc 12 which is integrally formed with the lock nut 11 and is located at the bottom of the lock nut 11, and the multiple integral bendable claws 15 which are evenly arranged on the circumferential surface of the nut disc 12. Considering that the bendable claws 15 and the nut need to be easy to bend and ensure strength, and also considering cost factors, the lock nut 11, the nut disc 12 and the bendable claws 15 in this application are all made of carbon steel. Carbon steel has high strength and can withstand greater pressure and tension. Carbon steel has high strength and toughness, is easy to process and bend, and has a relatively low cost. In addition, in order to enhance corrosion resistance, the carbon steel surface can be galvanized, painted or otherwise treated.

[0033] The stop gear 21, multiple integrated retaining teeth 22 evenly arranged on the circumferential surface of the stop gear 21, and a stop block 23 set on the inner wall of the stop gear 21 and corresponding to the stop platform 31 reserved on the steering knuckle 3. The stop block 23 must be matched with the stop platform 31 reserved on the steering knuckle 3 during the initial processing to ensure that the stop gear 21 is fitted on the steering knuckle 3 later. The stop block 23 can cooperate with the stop platform 31 to play the role of stopping and preventing rotation.

[0034] The assembleable rotating structure located between the nut disc 12 and the stop gear disc 21 allows them to be assembled into a single unit. Compared to the traditional steering knuckle shaft locking device where multiple parts are assembled one by one, this application allows for direct assembly into a single unit, enabling rapid assembly of individual parts and facilitating subsequent direct installation. This improves the assembly convenience of the entire device and makes it easy to assemble. Furthermore, the nut disc 12 and the stop gear disc 21 have good stability after assembly and are not easily separated. When the nut disc 12 and the locking nut 11 are subsequently locked and rotated, the stop gear disc 21 will not rotate with it, ensuring normal subsequent installation.

[0035] In this embodiment, preferably, the assemblable rotating structure includes an annular groove 16 formed on the inner wall of the nut disc 12 and a 15° thin-walled conical opening structure 24 provided on the top surface of the stop gear disc 21. Considering that the thin-walled conical opening structure 24 needs to facilitate subsequent extrusion and ensure strength, and also considering cost factors, both the nut disc 12 and the thin-walled conical opening structure 24 in this application are made of carbon steel. Carbon steel has high strength and can withstand greater pressure and tension. Carbon steel has high strength and toughness, is easy to process and bend, and has a relatively low cost. The thin-walled conical opening structure 24 can be slightly deformed by extrusion and inserted into the annular groove 16. The thin-walled conical opening structure 24 can be slightly deformed by extrusion and squeezed into the annular groove 16 to cooperate with the annular groove 16, so that when the nut disc 12 and the locking nut 11 rotate, the stop gear disc 21 will not rotate, and at the same time, it can be stably assembled together with the nut disc 12 and the stop gear disc 21. Figure 9 As shown, the thin-walled conical opening structure 24 can be slowly squeezed into the annular groove 16 from the conical inlet on the bottom surface of the nut disc 12 by extrusion until the nut disc 12 and the stop toothed disc 21 are assembled and secure.

[0036] In this embodiment, preferably, the bottom surface of the nut disc 12 is provided with a tapered inlet that communicates with the annular groove 16. The tapered inlet design facilitates the subsequent insertion of the thin-walled tapered opening structure 24 into the annular groove 16. It also acts as a guide when the thin-walled tapered opening structure 24 is inserted into the annular groove 16, making it easier for the thin-walled tapered opening structure 24 to be inserted into the annular groove 16. This avoids errors during extrusion that could lead to assembly failure, thereby improving the assembly efficiency and success rate between the nut disc 12 and the locking nut 11.

[0037] In this embodiment, preferably, the inner wall of the top end of the locking nut 11 is provided with an inner chamfer of 2*45° 13. The design of the inner chamfer 13 on the inner wall of the top end of the locking nut 11 can prevent the locking nut 11 from damaging the threads on the surface of the steering knuckle 3 during subsequent locking and installation, thus fully ensuring the integrity of the threads on the surface of the steering knuckle 3.

[0038] In this embodiment, preferably, the outer wall of the top end of the locking nut 11 is provided with a 30° external chamfer 14, which can prevent the outer wall of the top end of the locking nut 11 from being bumped or squeezed by foreign objects during transportation or assembly, thus ensuring the integrity of the locking nut 11. At the same time, this external chamfer 14 on the outer wall of the top end of the locking nut 11 can also facilitate the smooth insertion of the locking sleeve during subsequent installation, and play a guiding role in the insertion of the sleeve tool, and also avoid the outer wall of the top end of the locking nut 11 being bumped or deformed when the locking sleeve is inserted.

[0039] In this embodiment, preferably, there are ten bendable claws 15, which are evenly distributed on the circumferential surface of the nut disc 12, and thirty locking teeth 22, which are evenly distributed on the circumferential surface of the stop tooth disc 21. At the same time, the size of the bendable claws 15 and the size of the locking teeth 22 are matched, so that the bendable claws 15 can be smoothly bent and locked between two adjacent locking teeth 22.

[0040] In this embodiment, preferably, the width of the bendable claw 15 is three millimeters, and the thickness of the bendable claw 15 is three millimeters.

[0041] In this embodiment, preferably, the width of the locking tooth 22 is four millimeters, and the thickness of the locking tooth 22 is six millimeters.

[0042] In summary, when using this device, first assemble the locking nut 11 and the stop gear 21 into a whole. During assembly, simply squeeze the thin-walled conical opening structure 24 into the annular groove 16 by mechanical extrusion to complete the assembly between the locking nut 11 and the stop gear 21. This also ensures that the stop gear 21 will not rotate when the locking nut 11 rotates. Then, put the assembled locking nut 11 and stop gear 21 onto the steering knuckle 3, and make the stop block 23 cooperate with the stop platform 31 reserved on the steering knuckle 3. After gradually tightening the locking nut 11, bend the end of the bendable disc claw 15 into the two adjacent teeth 22 by mechanical extrusion to prevent the locking nut 11 from loosening. The stop gear 21 achieves anti-rotation and stop function through the cooperation of the stop block 23 and the stop platform 31.

[0043] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
