Description

Technical Field

[0001] This invention relates to the technical field of tire testing, and in particular to a dynamic load tire impact testing system. Background Technology

[0002] In the aerospace and engineering vehicle industries, most manufacturers use dedicated tire testing benches to test the dynamic impact performance of tires.

[0003] In the prior art, patent document CN209327002U discloses a dynamic mechanical performance testing system for tires, including a test bench, a bracket mounted on the test bench, and an auxiliary power device. The tire is mounted on the bracket via connecting shafts on both sides, and the connecting shafts are rotatably connected to the bracket via bearings. The auxiliary power device drives the tire to rotate. A drop hammer is also provided on the test bench to provide a downward impact load to the tire. A pressure sensor is provided on the upper surface of the test bench, positioned below the tire, and is used to measure the force on the tire under the impact load. The dynamic mechanical performance testing system for tires described in this invention can effectively test the dynamic mechanical performance of tires, measuring the force, displacement, and pressure changes within the tire under impact loads at a certain rotational speed.

[0004] During use, it was found that, especially for aircraft tires or racing tires, dynamic impact testing under load is still required. The aforementioned device can only perform dynamic impact testing on tires under no-load conditions, which limits its use. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a dynamic load tire impact testing system for performing various performance tests on tires.

[0006] This invention discloses a dynamic load tire impact testing system, comprising a base, support frames, a first bearing seat, side plates, a top plate, a controller, and optical bars. Two sets of support frames are symmetrically arranged at the top of the base, each set of support frames having a first bearing seat at its top. A set of side plates is arranged on the left and right sides of the top of the base, with the tops of both sets of side plates connected to the bottom of the top plate. A controller is located at the outer end of one set of side plates. Multiple sets of optical bars are vertically arranged between the base and the top plate. The system also includes an impact component and a load component. The impact component is mounted on the optical bars, and the load component is located at the top of the base, between the two sets of support frames. In use, a tire is mounted on a test wheel hub, and the wheel hub is equipped with… It has a rotating shaft, which is interference-fitted with bearings on two sets of bearing housings. When a static no-load impact test is required on the tire, the operator operates the controller to cause the impact component to impact the stationary tire. When a static load impact test is required, the operator operates the load component to apply a load weight to the stationary tire, and then operates the impact component to perform a static load test. When a dynamic load impact test is required, the operator operates the load component to apply a load weight to the stationary tire, then operates the load component to drive the tire to rotate, and then operates the impact component to perform a dynamic load impact test. This improves the diversity of tests and increases testing efficiency.

[0007] Preferably, the impact assembly includes a U-shaped frame, a first inclined end, a slot, a lead screw, a counterweight, a handle, a wing nut, a first slider, a lifting assembly, and a release assembly. A set of first sliders is provided at each of the four corners of the U-shaped frame, and a set of first sliding sleeves is provided on each set of first sliders. Each set of first sliding sleeves is slidably fitted onto the outside of a set of guide rods. A set of first inclined ends is provided on both sides of the top of the U-shaped frame, with the two sets of first inclined ends symmetrically arranged. A set of slots is provided on the left and right sides of the U-shaped frame. A lead screw is provided at the bottom of the U-shaped frame. A positioning hole is provided on the counterweight, and the lead screw passes through the positioning hole of the counterweight and is threadedly connected to the wing nut. A handle is provided at the top of the counterweight. A lifting assembly is provided on the top plate. The device features a fixed, sliding release assembly. During use, according to the requirements of the tire impact test, the operator selects an appropriate amount of counterweight and places it inside the U-shaped frame. The lead screw passes through the handle, and the wing nut is threaded into the lead screw, thus completing the counterweight adjustment of the U-shaped frame. In use, the lifting assembly, with the cooperation of the two sets of No. 1 inclined planes, is hooked onto two sets of slots. The lifting assembly then raises the U-shaped frame. When the U-shaped frame reaches the designated height, the release assembly releases the hook from the U-shaped frame, allowing the U-shaped frame and multiple sets of counterweights to undergo free fall. This allows the U-shaped frame and multiple sets of counterweights to work together to conduct the tire impact test. The lifting assembly automatically lifts the U-shaped frame and automatically releases it at the designated height, improving flexibility and convenience.

[0008] Preferably, the hoisting assembly includes a lifting frame, a second sliding sleeve, slots, a rotating shaft, vertical rods, locking blocks, a second inclined end, diagonal rods, a servo motor, a winding drum, ropes, and a second bearing seat. The servo motor and the second bearing seat are fixedly installed at the top of the top plate. A rotating shaft is provided at the output end of the servo motor, and a winding drum is fixedly installed on the rotating shaft. The rotating shaft is interference-fitted with the bearing on the second bearing seat. Ropes are wound on the winding drum. The lifting frame is provided with multiple sets of second sliding sleeves, each set of second sliding sleeves being slidably connected to the outer wall of a set of guide bars. A set of slots is provided at each of the left and right ends of the lifting frame. Vertical rods are rotatably installed in the slots via the rotating shaft. A torsion spring is provided on the rotating shaft. Locking blocks are provided at the bottom of the adjacent ends of two sets of vertical rods. A set of second inclined ends is provided at the bottom of each set of locking blocks, and the two sets of second inclined ends are symmetrically arranged. A set of diagonal rods is provided at the top of each set of vertical rods, and the two sets of diagonal rods are symmetrically arranged. The free end of the rope is connected to the top of the lifting frame. In use… The operator uses a controller to drive the servo motor to rotate the winding drum, which in turn unwinds the rope. This causes the lifting frame to move downwards along the guide bar with the assistance of the second sliding sleeve. When the second inclined surface of the two sets of locking blocks contacts the first inclined surface of the two sets of locking blocks at the top of the U-shaped frame, the bottom ends of the two sets of vertical rods move away in a mirror-image motion. As the lifting frame continues to descend, when the two sets of locking blocks coincide with the two sets of locking slots, the torsion spring causes the bottom ends of the two sets of vertical rods to move closer in a mirror-image motion, allowing the two sets of locking blocks to enter their respective slots. The operator then uses the controller to reverse the servo motor, causing the winding drum to wind the rope. As the lifting frame rises, when the inclined rod contacts the release component, the two sets of inclined rods move closer in a mirror-image motion while the two sets of locking blocks move away in a mirror-image motion, releasing the U-shaped frame. The U-shaped frame and multiple counterweights then undergo a free-fall impact test on the tires, achieving automatic hoisting and release of the U-shaped frame and improving operational convenience.

[0009] Preferably, the release assembly includes a positioning plate, a No. 3 sliding sleeve, a strip groove, an internal thread seat, and a wing bolt. The positioning plate is provided with multiple sets of No. 3 sliding sleeves, each set of which is slidably connected to the outer wall of a set of optical bars. Each set of optical bars is provided with a strip groove. The positioning plate is provided with an internal thread seat, each set of which is threadedly connected to a set of wing bolts. According to the test requirements, the positioning plate slides on the optical bars with the cooperation of the No. 3 sliding sleeves. After reaching the required height, the operator rotates the wing bolt. Because the wing bolt is threadedly connected to the internal thread seat, one end of the wing bolt extends into the strip groove and presses against the inner side of the strip groove, thus fixing the positioning plate. When the lifting frame rises, when the top of the inclined rod and the bottom of the positioning plate simultaneously come into contact, the tops of the two sets of inclined rods move closer in a mirror image while the two sets of locking blocks move further apart in a mirror image, thus releasing the U-shaped frame and enabling its free fall, improving flexibility.

[0010] Preferably, the load assembly includes a hydraulic cylinder, pressure sensors, a support plate, guide rods, a lifting seat, a roller body, and a drive motor. The hydraulic cylinder has a support plate at its bottom, and a set of pressure sensors is located at each of the four corners of the support plate. The bottom ends of all four pressure sensors are fixedly connected to the top of the base. The movable end of the top of the hydraulic cylinder is connected to the bottom of the lifting seat. The roller body is rotatably mounted inside the lifting seat, and a drive motor is located at the outer end of the lifting seat. The output end of the drive motor is connected to one end of the roller body. Multiple guide rods are located at the top of the base, and the guide rods are slidably connected to the lifting seat. This configuration is used when a static load impact test is required on the tire. During static load impact testing, the operator extends the hydraulic cylinder via the controller, causing the lifting platform to apply a load to the tire under the guidance of the guide rod. When a dynamic load impact test is required, the operator extends the hydraulic cylinder, bringing the roller into contact with the tire, and then starts the drive motor. This causes the roller to apply a load to the tire while simultaneously rotating it. The impact assembly then performs the dynamic load impact test, and the load weight is detected by a pressure sensor, improving the flexibility and convenience of tire testing.

[0011] Preferably, it also includes an annular flat washer, and the lead screw is fitted with an annular flat washer; after the lead screw passes through the positioning holes of multiple sets of counterweights, the annular flat washer is fitted on the outside of the lead screw, and then the wing nut is threaded to the lead screw. The lead screw increases the contact area with the top of the counterweight through the annular flat washer, which improves the firmness and avoids the wear of the top of the counterweight by the wing nut.

[0012] Preferably, it also includes a guide wheel, which is rotatably provided at the top of the inclined rod; when the inclined rod is provided with a guide wheel, the guide wheel rotates adaptively when it comes into contact with the bottom end of the positioning plate, so as to avoid hard friction between the inclined rod and the bottom end of the positioning plate and reduce friction loss.

[0013] Preferably, the base also includes fixing plates and locking bolts. A set of fixing plates is provided at each of the four corners of the bottom of the base, and a set of locking bolts is provided on each of the fixing plates. The four sets of fixing plates cooperate with each other to provide stable support for the base. Then the locking bolts pass through the fixing plates and are threaded to the support surface, which improves the overall test stability of the equipment and prevents the equipment from tipping over.

[0014] Preferably, it also includes a protective plate, which is provided between the two sets of side plates. The protective plate is hinged to one set of side plates by a hinge. When the tire is subjected to an impact test, the protective plate seals the front end of the two sets of side plates with the help of the hinge, preventing personnel from accidentally entering between the two sets of side plates during the test, which could cause injury to the personnel who accidentally enter during the impact test, thus improving safety.

[0015] Preferably, the inner end of the strip groove is provided with multiple sets of anti-slip protrusions in the transverse direction, and the anti-slip protrusions are long strips; when fixing the positioning plate, rotate the wing bolt so that one end of the wing bolt extends into the strip groove and presses against the anti-slip protrusion, thereby improving the locking firmness of the positioning plate.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: In use, the tire is mounted on a test wheel hub, and a rotating shaft is provided on the wheel hub. The rotating shaft is interference-fitted with the bearings on two sets of bearing seats No. 1. When a static no-load impact test is required on the tire, the operator operates the controller to cause the impact component to impact the stationary tire. When a static load impact test is required on the tire, the operator operates the load component to apply a load weight to the stationary tire, and then operates the impact component to perform a static load test on the tire. When a dynamic load impact test is required on the tire, the operator operates the load component to apply a load weight to the stationary tire, then operates the load component to drive the tire to rotate, and then operates the impact component to perform a dynamic load impact test on the tire. This improves the diversity of tests and increases the testing efficiency. Attached Figure Description

After reaching the required height, the operator rotates the wing bolt 405. Since the wing bolt 405 is threadedly connected to the internal thread seat 404, one end of the wing bolt 405 extends into the strip groove 403 and presses against the inner side of the strip groove 403, thereby completing the fixation of the positioning plate 401.

As the lifting frame 301 continues to descend, when the two sets of locking blocks 306 coincide with the two sets of locking slots 203, the torsion spring causes the bottom ends of the two sets of vertical rods 305 to move closer in a mirror image, so that the two sets of locking blocks 306 enter the corresponding locking slots 203 respectively. Then, the operator operates the servo motor 309 to reverse through the controller 106, thereby rewinding the device. The cylinder 310 winds up the rope 311. As the lifting frame 301 rises, when the guide wheel 313 on the inclined bar 308 contacts the bottom of the positioning plate 401, the two sets of guide wheels 313 rotate adaptively. Simultaneously, the two sets of inclined bars 308 move closer together and the two sets of locking blocks 306 move further apart, thus releasing the U-shaped frame 201. The U-shaped frame 201 and multiple sets of counterweights 205 fall freely to conduct an impact test on the tire, achieving automatic hoisting and release of the U-shaped frame 201. When a static load impact test on the tire is required, the operator operates the hydraulic cylinder through the controller 106. 501 extends, so that the lifting seat 505, under the guidance of the guide rod 504, causes the roller body 506 to apply a load weight to the tire, thereby conducting a static load impact test on the tire. When a dynamic load impact test is required, the operator operates the hydraulic cylinder 501 to extend, so that the roller body 506 comes into contact with the tire, and then starts the drive motor 507, so that the roller body 506 applies a load weight to the tire while driving the tire to rotate. Then, the impact component conducts a dynamic load impact test on the tire, and the load weight is detected by the pressure sensor 502.

[0024] The main functions achieved by this invention are: 1. Enables static no-load impact testing, static load impact testing, and dynamic load impact testing of tires; 2. With the cooperation of the second inclined end 307, the two sets of locking blocks 306 abut against the two sets of first inclined ends 202, so that the two sets of locking blocks 306 move away from each other. When the locking blocks 306 coincide with the slots 203, the torsion spring causes the two sets of locking blocks 306 to enter the slots 203 respectively, thereby raising the U-shaped frame 201. When the top of the inclined rod 308 abuts against the bottom of the positioning plate 401, the two sets of locking blocks 306 move away from the two sets of slots 203, thereby realizing the automatic hoisting and automatic release of the U-shaped frame 201.
