[0053] In some embodiments of the present application, a tire rigidity testing machine is provided, referring to Figure 1 The tire rigidity testing machine can perform radial rigidity test, longitudinal rigidity test, lateral rigidity test, torsional rigidity test, static load test, strength test, etc. on tires. The outer diameter of the tire that can be tested can be up to 4200mm, which is a large engineering tire. The tire rigidity testing machine of the present application is a horizontal structure.

[0054] The tire rigidity testing machine comprises a work station shaft assembly 20. The work station shaft assembly 20 comprises a work station shaft 400. The work station shaft 400 is horizontally arranged. The work station shaft 400 is configured to mount a tire 40 to be tested. Figure 6 A structural view of the work station shaft assembly 20 is shown in Figure 8 A sectional view of the work station shaft assembly 20 is shown in Figure 9 A structural view of the work station shaft 400 is shown in

[0055] The tire rigidity testing machine further comprises a tire loading system 10. The tire loading system 10 is arranged beside the work station shaft 400. In other words, the work station shaft assembly 20 and the tire loading system 10 are arranged in sequence along the horizontal direction. Figure 2 A structural view of the tire loading system 10 is shown in Figure 3 A structural view of the tire loading system 10 is shown in Figure 5 A sectional view of the tire loading system 10 is shown in

[0056] The tire rigidity testing machine further comprises a machine frame 30. The work station shaft assembly 20 and the tire loading system 10 are arranged on the machine frame 30.

[0057] The tire loading system 10 comprises a radial loading portion 100. The radial loading portion 100 is configured to move towards or away from the tire 40. The radial loading portion 100 is in sliding connection with the machine frame 30, and the radial loading portion 100 moves horizontally along the machine frame 30.

[0058] The tire loading system 10 further comprises a torsional portion 200. The torsional portion 200 is arranged on the radial loading portion 100.

[0059] The tire loading system 10 further comprises a longitudinal-lateral loading portion 300. The longitudinal-lateral loading portion 300 is connected with the torsion portion 200. The torsion portion 200 is configured to drive the longitudinal-lateral loading portion 300 to rotate. The torsion portion 200 drives the longitudinal-lateral loading portion 300 to rotate in a vertical plane.

[0060] The longitudinal-lateral loading portion 300 has a first rotation position and a second rotation position. Figure 2 The longitudinal-lateral loading portion 300 is in the first rotation position. Figure 4 The longitudinal-lateral loading portion 300 is in the second rotation position.

[0061] In an embodiment, the first rotation position is a vertical position, and the second rotation position is a horizontal position. The torsion portion 200 drives the longitudinal-lateral loading portion 300 to switch between the first rotation position and the second rotation position.

[0062] With reference to Figure 2 , the longitudinal-lateral loading portion 300 is configured to move in a first direction to perform a longitudinal stiffness test on the tire 40 when the longitudinal-lateral loading portion 300 is in the first rotation position.

[0063] In an embodiment, the first direction is a vertical direction. The longitudinal-lateral loading portion 300 is configured to move in the vertical direction to perform a longitudinal stiffness test on the tire 40 when the longitudinal-lateral loading portion 300 is in the first rotation position.

[0064] In other words, when the tire 40 is subjected to a longitudinal stiffness test, the longitudinal-lateral loading portion 300 is in the first rotation position as shown in Figure 2 , the radial loading portion 100 moves towards the tire 40, driving the longitudinal-lateral loading portion 300 to move towards the tire 40 synchronously, until the longitudinal-lateral loading portion 300 abuts against the tire 40, and the longitudinal-lateral loading portion 300 moves in the vertical direction to perform a longitudinal stiffness test on the tire 40.

[0065] With reference to Figure 4 , the longitudinal-lateral loading portion 300 is configured to move in a second direction to perform a lateral stiffness test on the tire 40 when the longitudinal-lateral loading portion 300 is in the second rotation position.

[0066] In an embodiment, the second direction is a horizontal direction. The longitudinal-lateral loading portion 300 is configured to move in the horizontal direction to perform a lateral stiffness test on the tire 40 when the longitudinal-lateral loading portion 300 is in the second rotation position.

[0067] In other words, when the tire 40 is subjected to a lateral stiffness test, the longitudinal-lateral loading portion 300 is in the second rotation position as shown in Figure 4In the second rotation position shown, the radial loading part 100 moves towards the tire 40, and the longitudinal and lateral loading part 300 is driven to move towards the tire 40 synchronously, until the tire 40 is abutted, and the longitudinal and lateral loading part 300 moves horizontally to perform a lateral rigidity test on the tire 40.

[0068] In the radial rigidity test on the tire 40, the longitudinal and lateral loading part 300 does not move vertically or horizontally, the radial loading part 100 moves towards the tire 40, and the longitudinal and lateral loading part 300 is driven to move towards the tire 40 synchronously, until the tire 40 is abutted, and the radial loading part 100 continues to press to perform a radial rigidity test on the tire 40.

[0069] The tire loading system 10 includes the radial loading part 100, the torsion part 200, and the longitudinal and lateral loading part 300. The torsion part 200 is arranged on the radial loading part 100, and drives the longitudinal and lateral loading part 300 to rotate in the vertical plane to change the position state of the longitudinal and lateral loading part 300, and then combines the vertical movement and the horizontal movement of the longitudinal and lateral loading part 300 to perform a radial rigidity test, a longitudinal rigidity test, or a lateral rigidity test on the tire 40. The longitudinal loading and the lateral loading are driven by the same loading mechanism, the overall structure of the tire loading system 10 is compact, and the components cooperate with each other to meet the different test requirements of the tire 40.

[0070] In some embodiments of the present application, the workbench shaft 400 has a locking state. When performing a rigidity test on the tire 40, such as a radial rigidity test, a longitudinal rigidity test, a lateral rigidity test, or a torsion rigidity test, the workbench shaft 400 is in the locking state, and the workbench shaft 400 does not rotate.

[0071] The workbench shaft 400 also has a rotating state. When performing a puncture strength test on the tire 40, the workbench shaft 400 is in the rotating state, and the workbench shaft 400 can rotate, and the workbench shaft 400 drives the tire 40 mounted thereon to rotate synchronously.

[0072] The tire loading system 10 also includes a puncture part (not shown). The puncture part is detachably connected with the longitudinal and lateral loading part 300. For example, the puncture part is a puncture rod structure, and the puncture part is connected with the longitudinal and lateral loading part 300 by clamping, bolts, or the like.

[0073] The tire rigidity tester can also perform a puncture strength test on the tire 40. When performing the puncture strength test on the tire 40, the puncture part is mounted on the longitudinal and lateral loading part 300. When the puncture strength test is not needed on the tire 40, the puncture part is removed from the longitudinal and lateral loading part 300.

[0074] When performing a puncture strength test on tire 40, multiple puncture test points, such as five, are set along the circumference of tire 40. The puncture part is installed on the longitudinal and transverse loading parts 300. The station shaft 400 is initially locked. The radial loading part 100 moves towards the tire 40, causing the longitudinal and transverse loading parts 300 to move synchronously towards the tire 40. The radial loading part 100 continues to apply pressure, and the puncture part punctures the first puncture test point of tire 40 to perform a puncture strength test on tire 40. After the first puncture test point is completed, the radial loading part 100 moves away from the tire 40, the puncture part disengages from the tire 40, and then the station shaft 400 switches to the rotation state, driving the tire 40 to rotate so that the tire 40 rotates to the second puncture test point facing the puncture part. The station shaft 400 then switches to the locking state, and then the radial loading part 100 moves towards the tire 40, so that the puncture part punctures the second puncture test point. This process is repeated to complete the puncture strength test of the remaining puncture test points.

[0075] By setting the workstation shaft 400 to have both a locked state and a rotating state, the requirements for the tire 40 puncture strength test are met.

[0076] In some embodiments of this application, the tire rigidity testing machine can also perform torsional stiffness tests on the tire 40. When the tire rigidity testing machine performs a torsional stiffness test on the tire 40, the torsion section 200 drives the longitudinal and transverse loading sections 300 to reciprocate within a set angle range.

[0077] Specifically, when the tire 40 is subjected to a torsional rigidity test, the radial loading part 100 moves toward the tire 40, which drives the longitudinal and transverse loading parts 300 to move toward the tire 40 at the same time, until they come into contact with the tire 40. The torsion part 200 drives the longitudinal and transverse loading parts 300 to reciprocate within a set angle range to perform a torsional rigidity test on the tire 40.

[0078] Furthermore, the initial position of the longitudinal and transverse loading parts 300 is set to a vertical state, that is... Figure 2 In the state shown, when conducting a torsional rigidity test, the torsion unit 200 drives the longitudinal and transverse loading units 300 to rotate at a certain angle, for example, 45°. Then, the torsion unit 200 drives the longitudinal and transverse loading units 300 to reciprocate within a set angle range, for example, within a range of ±15°.

[0079] In some embodiments of this application, the radial loading unit 100 includes a radial loading platform 110 and a radial loading cylinder (not shown). The radial loading cylinder drives the radial loading platform 110 to move towards or away from the tire 40. Figure 1 For example, the radial loading cylinder is located on the right side of the radial loading platform 110.

[0080] The radial loading platform 110 is in sliding connection with the rack 30. For example, the bottom of the radial loading platform 110 is provided with a first sliding part 111, and the rack 30 is correspondingly provided with a second sliding part 31, and the first sliding part 111 is in sliding connection with the second sliding part 31. For example, the first sliding part 111 is a sliding block, and the second sliding part 31 is a sliding rail.

[0081] In some embodiments of the present application, the torsion part 200 is arranged on the radial loading platform 110.

[0082] In some embodiments of the present application, the torsion part 200 includes a torsion platform 210 and a torsion driving part 220, and the torsion driving part 220 is configured to drive the torsion platform 210 to rotate. The torsion driving part 220 is arranged on the radial loading platform 110, and the torsion platform 210 is fixedly connected with the longitudinal and transverse loading part 300. The torsion driving part 220 drives the torsion platform 210 to rotate, and the torsion platform 210 drives the longitudinal and transverse loading part 300 to rotate synchronously.

[0083] In some embodiments of the present application, referring to Figure 3 and Figure 5 , the torsion driving part 220 includes a torsion driving cylinder 221, the power output end of the torsion driving cylinder 221 is provided with a crank 222, the crank 222 is provided with a connecting part 223, and the torsion platform 210 is fixedly connected with the connecting part 223. The torsion driving cylinder 221 is fixedly arranged on the radial loading platform 110. The connecting part 223 is in rotary connection with the radial loading platform 110.

[0084] The torsion driving cylinder 221 drives the crank 222 to move, the crank 222 drives the connecting part 223 to rotate, the connecting part 223 drives the torsion platform 210 to rotate synchronously, and further drives the longitudinal and transverse loading part 300 to rotate. Figure 3 The dashed line in represents different position states of the crank 222. The force is transmitted through the crank 222, and the structure is compact and reliable.

[0085] In some embodiments of the present application, referring to Figure 5 , the connecting part 223 includes a connecting shaft 2231 and a rotating disc 2232, one end of the connecting shaft 2231 is fixedly connected with the crank 222, and the other opposite end is fixedly connected with the rotating disc 2232. The radial loading platform 110 is provided with a through port 120, and the connecting shaft 2231 and the rotating disc 2232 pass through the through port 120, and the rotating disc 2232 is in rotary connection with the radial loading platform 110.

[0086] The rotary connection mode between the rotating disc 2232 and the radial loading platform 110 is not limited in the embodiment. For example, the rotary connection can be achieved through an annular protrusion and a groove.

[0087] The connecting portion 223 is arranged inside the radial loading table 110, and the overall structure is more compact, reducing the volume. The torsion driving cylinder 221 and the crank 222 are located on one side (for example, the rear side) of the connecting portion 223, and the torsion table 210 is located on the other side (for example, the front side) of the connecting portion 223, which facilitates the connection of the torsion table 210 and the longitudinal and transverse loading portion 300 while realizing force transmission.

[0088] In some embodiments of the present application, the longitudinal and transverse loading portion 300 includes a longitudinal and transverse loading table 310 and a longitudinal and transverse driving cylinder 320. The longitudinal and transverse driving cylinder 320 drives the longitudinal and transverse loading table 310 to move. The longitudinal and transverse driving cylinder 320 is fixedly arranged on the torsion table 210, and the longitudinal and transverse loading table 310 is slidingly arranged on the torsion table 210.

[0089] Specifically, the cylinder body of the longitudinal and transverse driving cylinder 320 is fixedly connected with the torsion table 210, and the power output end of the longitudinal and transverse driving cylinder 320 is fixedly connected with the longitudinal and transverse loading table 310.

[0090] The sliding connection structure between the torsion table 210 and the longitudinal and transverse loading table 310 is not specifically limited in the present embodiment. For example, a third sliding portion 311 is arranged on the longitudinal and transverse loading table 310, and a fourth sliding portion 211 is correspondingly arranged on the torsion table 210. The third sliding portion 311 is slidingly connected with the fourth sliding portion 211. For example, the third sliding portion 311 is a sliding block, and the fourth sliding portion 211 is a sliding rail.

[0091] The torsion table 210 rotates to drive the longitudinal and transverse loading table 310 to rotate synchronously, so as to switch the longitudinal and transverse loading table 310 between the first rotation position and the second rotation position, and to rotate the longitudinal and transverse loading table 310 within a set angle range when performing a torsion rigidity test.

[0092] When performing a longitudinal rigidity test, the longitudinal and transverse loading table 310 is in a vertical state as shown in FIG. 4, and the longitudinal and transverse driving cylinder 320 drives the longitudinal and transverse loading table 310 to move up and down. Figure 2

[0093] When performing a transverse rigidity test, the longitudinal and transverse loading table 310 is in a horizontal state as shown in FIG. 5, and the longitudinal and transverse driving cylinder 320 drives the longitudinal and transverse loading table 310 to move horizontally. Figure 4

[0094] In some embodiments of the present application, the puncture portion is detachably connected with the longitudinal and transverse loading portion 300, specifically, the puncture portion is detachably connected with the longitudinal and transverse loading table 310.

[0095] In some embodiments of the present application, the longitudinal and transverse driving cylinders 320 are arranged on opposite sides of the longitudinal and transverse loading table 310, respectively, to improve the movement stability of the longitudinal and transverse loading table 310.

[0096] ​​In some embodiments of the present application, the torsion part 200 further comprises a first sensor 230 configured to detect the pushing force of the torsion driving part 220. Specifically, referring to Figure 3 , the first sensor 230 is arranged between the torsion driving cylinder 221 and the crank 222 and is configured to detect the pushing force of the torsion driving cylinder 221 on the crank 222. The loading torque is calculated according to the pushing force.

[0097] In some embodiments of the present application, referring to Figure 2 , the longitudinal and transverse driving cylinders 320 are provided with a second sensor 330 configured to detect the longitudinal or transverse loading force.

[0098] In some embodiments of the present application, referring to Figure 9 , the work station shaft 400 is provided with a special-shaped shaft segment 410. The cross-sectional profile of the special-shaped shaft segment 410 is non-circular.

[0099] Referring to Figure 6 , the work station shaft assembly 20 further comprises two oppositely arranged first fixing seats 500. The first fixing seats 500 are arranged on the rack 30. Figure 10 is a structural view of the first fixing seat 500. The first fixing seat 500 is formed with a special-shaped mounting hole 510. The special-shaped mounting hole 510 is adapted to the special-shaped shaft segment 410, so that the work station shaft 400 is kept in a locked state. When the work station shaft 400 is locked, the work station shaft 400 cannot rotate, so as to facilitate the rigid test of the tire 40, such as the radial rigidity test, the longitudinal rigidity test, the transverse rigidity test, the torsion rigidity test, etc.

[0100] In some embodiments of the present application, the work station shaft assembly 20 further comprises two oppositely arranged second fixing seats 600. The second fixing seats 600 are arranged on the rack 30. The work station shaft 400 is rotationally connected with the second fixing seats 600. After the first fixing seat 500 releases the limiting of the work station shaft 400, the work station shaft 400 can rotate.

[0101] As described above, when the tire 40 is subjected to the puncture strength test and the puncture position is changed, the first fixing seat 500 releases the limiting of the work station shaft 400, the work station shaft 400 rotates, rotates to the next puncture point opposite to the puncture part, the work station shaft 400 stops rotating, and the first fixing seat 500 locks the work station shaft 400 again.
