Description

Technical Field

[0001] This application belongs to the field of steering parts. More specifically, it relates to a steering fork structure. Background Art

[0002] In existing automotive and other vehicle steering systems, the steering fork, as a key component, undertakes the important task of transmitting the steering force and connecting the steering knuckle and the wheel. However, due to the unreasonable design of the connection structure of the traditional steering fork, after the vehicle is subjected to complex and variable impact loads during driving, the connection part of the steering fork often loosens. This not only leads to a decrease in steering accuracy but also increases the wear between components, thereby affecting the overall life of the steering system. Therefore, it is necessary to solve the above technical problems. Summary of the Invention

[0003] The purpose of the embodiments of this application is to provide a steering fork structure to solve the technical problem of poor connection reliability of the steering fork in the prior art.

[0004] To achieve the above purpose, the technical solution adopted in this application is: providing a steering fork structure, including:

[0005] Fork feet, arranged in pairs at intervals;

[0006] A body, connected to the fork feet and forming a connection hole for connecting with a target object. The connection hole has straight hole walls and arc-shaped hole walls that are alternately distributed around its own central axis. The body also forms a dividing groove communicating with the connection hole and a locking hole communicating with the dividing groove and arranged at an angle to the dividing groove. The dividing groove is recessed from the surface of the body to the connection hole and its extending direction is parallel to the axial direction of the connection hole. The locking hole is recessed from the surface of the body to the dividing groove and is for installing a target fastener so that the groove walls of the dividing groove can approach or move away from each other.

[0007] Optionally, the fork feet form two bearing holes that are coaxial and spaced opposite to each other;

[0008] The bearing holes have a bearing hole center line that is in the same plane as the central axis of the connection hole.

[0009] Optionally, two straight hole walls are provided and are symmetrically arranged about the center line of the connection hole. The symmetric center plane of the two straight hole walls is arranged at an angle to the bearing hole center line.

[0010] Optionally, the two straight hole walls form an included angle of 60°.

[0011] Optionally, the dividing groove has a groove center line parallel to its own extending direction, and the groove center line is arranged at an angle to the bearing hole center line.

[0012] Optionally, the steering fork structure further has a perforation formed in and penetrating through one of the fork legs, and the split groove extends into the perforation and communicates with the perforation.

[0013] Optionally, the diameter of the perforation is greater than the wall spacing of the split groove.

[0014] Optionally, the locking hole includes threaded sections and smooth hole sections distributed on both sides of the split groove.

[0015] The beneficial effect of the steering fork structure provided by this application lies in that: compared with the prior art, in the steering fork structure provided by this application, the connection hole for connecting the target object has straight hole walls and arc-shaped hole walls that are alternately distributed around its own central axis. Since the split groove communicating with the connection hole and the locking hole communicating with the split groove are also provided on the body. Therefore, when the target fastener is installed in the locking hole and the walls of the split groove are brought closer to each other, the straight hole walls of the connection hole can more fully abut against the target object, so that the steering fork structure provided in this application has better connection reliability, far superior to the prior art.

[0030] Please refer to Figures 1 to 8 together, and now a steering fork structure provided by the embodiment of the present application will be described. This steering fork structure includes a fork foot 100 and a body 200. Specifically:

[0031] The fork feet 100 are arranged in pairs at intervals; the body 200 is connected to the fork feet 100 and forms a connection hole 201 for connecting with the target object. The connection hole 201 has a straight hole wall 202 and an arc-shaped hole wall 203 that are alternately distributed around its own central axis. The body 200 also forms a split groove 204 communicating with the connection hole 201 and a locking hole 205 communicating with the split groove 204 and arranged at an angle to the split groove 204. The split groove 204 is recessed from the surface of the body 200 into the connection hole 201 and the extending direction is parallel to the axial direction of the connection hole 201. The locking hole 205 is recessed from the surface of the body 200 into the split groove 204 and is for installing the target fastener so that the groove walls of the split groove 204 can approach or move away from each other. It can be understood that the angular setting between the split groove 204 and the locking hole 205 in this embodiment can be flexibly set according to actual needs. As a preferred embodiment, in this embodiment, taking the angular setting between the split groove 204 and the locking hole 205 as 73.06° as an example for illustration, it has a better locking effect.

[0032] According to the above structure provided in this embodiment, in the steering fork structure provided in this embodiment, the connection hole 201 for connecting the target object has a straight hole wall 202 and an arc-shaped hole wall 203 that are alternately distributed around its own central axis. Since the body is also provided with a split groove 204 communicating with the connection hole 201 and a locking hole 205 communicating with the split groove 204. Therefore, when the target fastener is installed in the locking hole 205 and the groove walls of the split groove 204 approach each other, the straight hole wall 202 of the connection hole 201 can more fully abut against the target object, so that the steering fork structure provided in this embodiment has better connection reliability, far superior to the prior art.

[0033] In another embodiment of the present application, please refer to Figures 1 to 8 , the fork feet 100 form two bearing holes 206 that are coaxial and spaced opposite to each other. The bearing holes 206 have a bearing hole center line 207 that is in the same plane as the central axis of the connection hole 201. In this embodiment, the fork feet 100 are connected to the object that fits with the fork feet 100 through the above bearing holes 206. According to the above structure provided in this embodiment, since the bearing hole center line 207 and the central axis of the connection hole 201 are in the same plane, the steering fork structure provided in this embodiment can be evenly stressed and bear a greater load during use, which is beneficial to further improving the connection reliability of the steering fork structure in this embodiment.

[0034] In another embodiment of the present application, please refer to Figures 1 to 8, two straight hole walls 202 are provided and symmetrically arranged with respect to the center line of the connecting hole 201, and the symmetry center plane of the two straight hole walls 202 is arranged at an angle with the bearing hole center line 207. According to the above structure provided in this embodiment, on the one hand, the two symmetrically arranged straight hole walls 202 can enable the connecting hole 201 to form a more stable connection with the target object; on the other hand, since the symmetry center plane of the two straight hole walls 202 is arranged at an angle with the bearing hole center line 207, the load-bearing capacity of the steering fork structure in this embodiment can be effectively improved. It can be understood that in actual production, the angle between the symmetry center plane of the two straight hole walls 202 and the bearing hole center line 207 can be flexibly set. As a preferred embodiment, in this embodiment, this angle is taken as 23.22° for illustration, which has better load-bearing capacity.

[0035] In another embodiment of the present application, please refer to Figures 1 to 8 , the two straight hole walls 202 form an included angle of 60°. According to the above structure provided in this embodiment, the connecting hole 201 can be more stably connected to the target object, which is beneficial to further improving the connection reliability of the steering fork structure in this embodiment.

[0036] In another embodiment of the present application, please refer to Figures 1 to 8 , the split groove 204 has a groove center line 208 parallel to its own extension direction, and the groove center line 208 is arranged at an angle with the bearing hole center line 207. According to the above structure provided in this embodiment, since the bearing hole center line 207 passes through the center of the connecting hole 201, the split groove 204 arranged at an angle with the bearing hole center line 207 also deviates from the center of the connecting hole 201. In this way, after the groove walls of the split groove 204 are locked by the locking parts and approach each other, the connecting hole 201 can be more stably clamped on the target object, which is beneficial to further improving the connection reliability of the steering fork structure in this embodiment. It can be understood that in actual production, the angle between the groove center line 208 of the split groove 204 and the bearing hole center line 207 can be flexibly set. As a preferred embodiment, in this embodiment, this angle is taken as 6.28° for illustration.

[0037] In another embodiment of the present application, please refer to Figures 1 to 8, the steering fork structure further has a perforation 209 formed and penetrating through one of the fork feet, and the split groove 204 extends to and communicates with the perforation 209. According to the above structure provided in this embodiment, the perforation 209 communicating with the split groove 204 can enable the body on both sides of the split groove 204 to have a larger deformation space, so that the connecting hole 201 can be more tightly held on the target object, which is beneficial to further improving the connection reliability of the steering fork structure in this embodiment. In addition, the perforation 209 provided on the fork foot 100 can also reduce the stress concentration on the fork foot 100, which is beneficial to further improving the load-bearing capacity of the steering fork structure in this embodiment.

[0038] In another embodiment of the present application, please refer to Figures 1 to 8 , the diameter of the perforation 209 is larger than the wall spacing of the split groove 204. According to the above structure provided in this embodiment, the perforation 209 with a diameter larger than the wall spacing of the split groove 204 can enable the body on both sides of the split groove 204 to have a larger deformation space, and thus the connecting hole 201 can be more tightly held on the target object, which is beneficial to further improving the connection reliability of the steering fork structure in this embodiment.

[0039] In another embodiment of the present application, please refer to Figures 1 to 8 , the locking hole 205 includes threaded sections 210 and smooth hole sections 211 distributed on both sides of the split groove 204. According to the above structure provided in this embodiment, the target fastener for installation in the locking hole 205 can be a structure such as a bolt or a screw commonly used in the art. By only setting the threaded hole on one side, the adjustment of the wall spacing of the split groove 204 can be realized, which is beneficial to significantly reducing the production cost of the steering fork structure in this embodiment.

[0040] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
