[0054] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0055] like Figures 1-4 As shown, the steering wheel assembly 1 includes a steering wheel 11 and a brake disc 12. The brake disc 12 and the steering wheel 11 are coaxially arranged and detachably connected. A first bearing 110 is detachably provided at the center of the steering wheel 11, and a second bearing 120 is detachably provided at the center of the brake disc 12. Specifically, the steering wheel 11 has a metal hub and a rubber wheel fitted on the metal hub. The metal hub has six through holes for bolts to pass through, and the brake disc 12 has six corresponding threaded holes. The six bolts pass through two through holes and are threaded into the six threaded holes, detachably connecting the steering wheel 11 and the brake disc 12. When it is necessary to disassemble the steering wheel 11 and the brake disc 12, it is only necessary to unscrew the six bolts one by one, making disassembly and assembly simple.

[0056] like Figures 5-7As shown, the detection device for the steering wheel assembly 1 of the embodiment mainly comprises a mounting seat 2, a clamping module 3, a driving module 4, a flatness detection table 5, a pushing screw rod 6 and a rotating speed detection table 7. The clamping module 3 mainly comprises a first clamping shaft 31 and a second clamping shaft 32. The driving module 4 mainly comprises a first motor 41, a second motor 42, a motor seat 43 and a driving wheel 44.

[0057] The mounting seat 2 comprises a first mounting plate 21 and a second mounting plate 22 which are arranged in parallel and are fixedly connected by a bottom plate perpendicular to the two mounting plates. A plurality of reinforcing ribs are arranged between the first mounting plate 21 and the vertical plate and between the second mounting plate 22 and the vertical plate to ensure the overall strength of the mounting seat 2.

[0058] The clamping module 3 is used for clamping the steering wheel assembly 1. The clamping module 3 comprises coaxially arranged first and second clamping shafts 31 and 32 which are arranged on the first and second mounting plates 21 and 22 respectively. The first and second clamping shafts 31 and 32 each have a clamping protrusion 312 on the outer periphery thereof. One of the first and second clamping shafts 31 and 32 is telescopically movable so that the first and second clamping shafts 31 and 32 can clamp or loosen the steering wheel assembly 1. Specifically, the first clamping shaft 31 is telescopically movable, i.e., the first clamping shaft 31 is a screw rod. A second nut structure 26 is arranged on the first mounting plate 21, and the first clamping shaft 31 is arranged in the second nut structure 26 to form a screw nut structure, so that the first clamping shaft 31 can be telescopically moved. One end of the first clamping shaft 31 is provided with a second rotating handle 310 to facilitate the rotation of the first clamping shaft 31 and control the telescopic movement thereof. When the first clamping shaft 31 is adjusted to the desired position, the second rotating handle 310 can be locked to lock the position of the first clamping shaft 31. When the first clamping shaft 31 approaches the second clamping shaft 32, the steering wheel assembly 1 can be clamped to ensure that the steering wheel assembly is not shaken after being clamped and positioned and has good structural stability. When the first clamping shaft 31 moves away from the second clamping shaft 32, the steering wheel assembly 1 can be loosened. When the clamping module 3 clamps the steering wheel assembly 1, the first clamping shaft 31 penetrates into the first bearing 110, and the clamping protrusion 312 on the first clamping shaft 31 abuts against the side surface of the first bearing 110. The second clamping shaft 32 penetrates into the second bearing 120, and the clamping protrusion 312 on the second clamping shaft 32 abuts against the side surface of the second bearing 120. The steering wheel 11 and the brake disc 12 can rotate around the first and second clamping shafts 31 and 32.

[0059] Need to explain, when the first clamping shaft 31 and the second clamping shaft 32 clamp the steering wheel assembly 1, the steering wheel assembly 1 can rotate around the center of the first clamping shaft 31 and the second clamping shaft 32. During the clamping of the steering wheel assembly 1, the second clamping shaft 32 is first inserted into the inner ring of the second bearing 120 in the center of the brake disc 12, and then the second rotating handle 310 is rotated to move the first clamping shaft 31 towards the second clamping shaft 32, so that the first clamping shaft 31 is inserted into the inner ring of the first bearing 110 in the center of the steering wheel 11. When the clamping protrusions 312 on the first clamping shaft 31 abut against the side of the inner ring of the first bearing 110, and the clamping protrusions 312 on the second clamping shaft 32 abut against the side of the inner ring of the second bearing 120, the clamping of the steering wheel assembly 1 by the clamping module 3 is completed. Conversely, the steering wheel assembly 1 can be removed from the clamping module 3.

[0060] The driving module 4 includes a first motor 41, a second motor 42, a motor seat 43, and a driving wheel 44. The first motor 41 is fixedly installed on the motor seat 43, and the driving wheel 44 is arranged on the output shaft of the first motor 41. When the first motor 41 rotates, it can drive the driving wheel 44 to rotate. The motor seat 43 is movably arranged on the mounting seat 2, and the second motor 42 is arranged on the mounting seat 2 and can drive the motor seat 43 to move. Specifically, a guide rail 210 is arranged on the mounting seat 2, and a second sliding groove 430 is arranged on the motor seat 43. The guide rail 210 is arranged in the second sliding groove 430. The second sliding groove 430 is a dovetail groove arranged in the vertical direction, and the guide rail 210 matches the dovetail groove to ensure that the mounting seat 2 slides in and out of the groove without falling off the mounting seat 2. The second motor 42 is a lead screw motor, and a matching nut is arranged on the motor seat 43. The lead screw of the lead screw motor cooperates with the nut on the motor seat 43 to form a lead screw nut mechanism. The lead screw motor drives the motor seat 43 to move up and down, thereby driving the first motor 41 and the driving wheel 44 to move up and down. That is, after the clamping module 3 clamps the steering wheel assembly 1, the second motor 42 can drive the motor seat 43 to move, so that the driving wheel 44 contacts or separates from the steering wheel 11. When the driving wheel 44 contacts the rotating wheel, the driving wheel 44 can drive the steering wheel 11 through friction. In actual use, the extension and retraction of the motor seat 43 driven by the second motor 42 can drive the first motor 41 and the driving wheel 44 to move up and down, so that the rotating wheel and the steering wheel assembly 1 can contact and separate, that is, the steering wheel 11 can be rotated by the driving wheel 44 through friction from a stationary state, or it can gradually stop from a rotating state (the driving wheel 44 separates from the steering wheel assembly 1).

[0061] The flatness detection table 5 is arranged on the second mounting plate 22 and is used to detect the flatness of the brake disc 12. Specifically, the first sliding groove 220 is arranged on the second mounting plate 22 in the transverse direction, and the flatness detection table 5 is slidably arranged in the first sliding groove 220. Since the brake disc 12 needs to rotate at a high speed during the detection, the flatness detection table 5 in the embodiment can be adjusted by sliding along the first sliding groove 220 arranged in the transverse direction, i.e., adjusted along the radial direction of the brake disc 12, so that the flatness detection table 5 can detect the flatness of the outer side surface of the brake disc 12 comprehensively and ensure the accuracy of the detection result. The laser rotating speed detection table 7 is further arranged on the mounting seat 2, and the rotating speed detection table 7 is used to measure the rotating speed of the steering wheel assembly 1, i.e., the detection can be performed when the rotating speed of the steering wheel assembly 1 reaches a certain value during the actual detection.

[0062] As shown in Figures 7-11 The detection device in the embodiment is provided with the first positioning structure 23 and the second positioning structure 24 on the mounting seat 2, the first positioning structure 23 can position the steering wheel 11, and the second positioning structure 24 can position the brake disc 12. The mounting seat 2 is provided with the pushing screw rod 6, when the steering wheel 11 is positioned on the first positioning structure 23, the pushing screw rod 6 can push the first bearing 110 out of the steering wheel 11, and when the brake disc 12 is positioned on the second positioning structure 24, the pushing screw rod 6 can push the second bearing 120 out of the brake disc 12. Further, the second positioning structure 24 includes the forward clamping groove 241 and the reverse clamping groove 242 arranged symmetrically, the forward clamping groove 241 and the reverse clamping groove 242 can respectively position the brake disc 12 in the forward direction and the reverse direction, so as to facilitate the pushing of the second bearing 120 out of the brake disc 12 and the installation of the second bearing 120 into the brake disc 12. The steering wheel 11 can be positioned on the first positioning structure 23 in the forward direction and the reverse direction respectively, so as to facilitate the pushing of the first bearing 110 out of the steering wheel 11 and the installation of the first bearing 110 into the steering wheel 11. One end of the pushing screw rod 6 is provided with a pushing disc 61, the other end of the pushing screw rod 6 is provided with the first rotating handle 62, the mounting seat 2 is provided with the first nut structure 25 matched with the pushing screw rod 6, and the pushing screw rod 6 and the first nut structure 25 form a screw nut mechanism. In actual use, the first positioning structure 23 on the mounting seat 2 in the embodiment can position the steering wheel 11 in the forward direction and the reverse direction respectively, the second positioning structure 24 on the mounting seat 2 can position the brake disc 12 in the forward direction and the reverse direction respectively, and the mounting seat 2 is provided with the pushing screw rod 6, which facilitates the disassembly and assembly of the first bearing 110 and the second bearing 120, is convenient to use, and can effectively ensure the detection efficiency of the detection device.

[0063] The detection device of the embodiment is also provided with a standard steering wheel and a standard brake disc. The standard steering wheel can be assembled with the brake disc 12 to form the steering wheel assembly 1, and the standard brake disc can be assembled with the steering wheel 11 to form the steering wheel assembly 1. It needs to be explained that the standard steering wheel and the standard brake disc are both assembled to form the qualified steering wheel assembly 1, and the tolerance can be ignored. When the detection device detects that the steering wheel assembly 1 exceeds the allowable tolerance range, the standard steering wheel and the standard brake disc can be used to conveniently trace back to whether the first bearing 110 or the second bearing 120 needs to be replaced.

[0064] In actual use, the first clamping shaft 31 and the second clamping shaft 32 in the clamping module 3 of the embodiment respectively penetrate into the first bearing 110 and the second bearing 120 from both sides, and the clamping protrusions 312 thereon are respectively abutted against the side surface of the first bearing 110 and the side surface of the second bearing 120 to clamp and position the steering wheel assembly 1. The second motor 42 drives the motor seat 43 to move, so that the driving wheel 44 on the first motor 41 is in contact with the steering wheel 11 on the steering wheel assembly 1. The first motor 41 drives the driving wheel 44 to rotate to frictionally drive the steering wheel assembly 1 to rotate. The flatness value detected by the flatness detection table 5 can be used to judge whether the steering wheel assembly 1 is qualified. If the detected flatness value is within the allowable tolerance range, the steering wheel assembly 1 is qualified, that is, the first bearing 110 and the second bearing 120 are qualified. If it exceeds the allowable tolerance range, the steering wheel assembly 1 is disassembled into the steering wheel 11 and the brake disc 12, and then the disassembled steering wheel 11 is assembled with the standard brake disc, and the disassembled brake disc 12 is assembled with the standard steering wheel, and the two are respectively detected to determine whether the first bearing 110 or the second bearing 120 is unqualified.

[0065] In summary, the detection method for the steering wheel assembly 1 of the embodiment is applied to the detection device described above, and the detection method for the steering wheel assembly 1 comprises the following steps.

[0066] First, the steering wheel assembly 1 is clamped on the clamping module 3. The first clamping shaft 31 penetrates into the first bearing 110, and the clamping protrusion 312 on the first clamping shaft 31 abuts against the side surface of the first bearing 110. The second clamping shaft 32 penetrates into the second bearing 120, and the clamping protrusion 312 on the second clamping shaft 32 abuts against the side surface of the second bearing 120.

[0067] The second motor 42 drives the motor seat 43 to slide, so that the driving wheel 44 on the first motor 41 is in contact with the steering wheel on the steering wheel assembly 1. The first motor 41 drives the driving wheel 44 to rotate, and the driving wheel 44 frictionally drives the rotating wheel assembly to rotate, so that the rotating speed of the rotating wheel assembly reaches a preset value (the specific rotating speed can be measured by the laser rotating speed detection table 7).

[0068] The flatness detection table 5 detects the flatness of the brake disc 12;

[0069] When the value detected by the flatness detection table 5 is within the tolerance range, the steering wheel assembly 1 is qualified, i.e. the first bearing 110 and the second bearing 120 are qualified, and no replacement is needed. When the value detected by the flatness detection table 5 is out of the tolerance range, the steering wheel assembly 1 is disassembled into the steering wheel and the brake disc 12, the disassembled steering wheel is assembled with a standard brake disc, and then placed on the detection device for detection. If this detection is unqualified, it indicates that the first bearing 110 in the steering wheel is unqualified and needs to be replaced. If the detection is qualified, it indicates that the first bearing 110 in the steering wheel assembly 1 is qualified and no replacement is needed. Furthermore, the disassembled brake disc 12 is assembled with a standard steering wheel, and then placed on the detection device for detection. If this detection is qualified, it indicates that the second bearing 120 in the brake disc 12 is qualified and no replacement is needed. If the detection is unqualified, it indicates that the second bearing 120 is unqualified and needs to be replaced. Since the flatness of the brake disc 12 can be judged in advance by using a feeler gauge, the flatness of the brake disc 12 can be ensured to be qualified before the test.

[0070] In the scheme, the overall structure of the detection device is simple, the detection is comprehensive and accurate, and the operation during detection is convenient.
