Description

Technical Field

[0001] This utility model relates to the field of wheel hub pressure testing technology, specifically to an aluminum alloy wheel hub pressure testing platform. Background Technology

[0002] With the rapid development of the electric vehicle industry, wheel hubs, as a crucial component of vehicles, directly impact driving safety and stability through their performance and quality. During vehicle operation, wheel hubs not only bear vertical loads from the road surface but also dynamic camber changes caused by steering and bumps. Therefore, conducting load-bearing tests on wheel hubs, particularly testing their performance under dynamic camber changes, is a critical step in ensuring wheel hub quality and effectively preventing the need for factory repairs.

[0003] After production, aluminum alloy wheels need to undergo pressure testing. However, most common pressure testing methods are static tests, which test only a single surface or point of the wheel hub. They lack dynamic pressure testing of the wheel hub, resulting in incomplete data from subsequent tests. Furthermore, current pressure testing benches cannot simulate the changes in the wheel hub's pressure capacity when it tilts during steering, or when going uphill or downhill, thus failing to meet the testing requirements of different usage scenarios. This affects the overall measurement efficiency and accuracy.

[0004] Therefore, we propose an aluminum alloy wheel hub pressure test bench to solve the above problems. Utility Model Content

[0026] 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.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides an aluminum alloy wheel hub pressure test bench, including a bracket 1, arc-shaped frames 2 fixed at both ends of the top of the bracket 1, the arc-shaped frames 2 being symmetrically distributed along the vertical center line of the bracket 1, and an adjustment seat 3 distributed between the two arc-shaped frames 2, with holes on both sides of the top of the adjustment seat 3 for the longitudinal sliding of the guide rod 13.

[0029] A hydraulic cylinder 4 is fixedly installed at the top center of the adjusting seat 3, and the output end of the hydraulic cylinder 4 is connected to the lifting seat 5. A side plate 6 is fixedly installed on one side of the bottom of the lifting seat 5. The side plate 6 is symmetrically distributed along the vertical center line of the lifting seat 5. A guide block 7 is fixedly installed on the side wall of the adjusting seat 3. The guide block 7 is symmetrically distributed on both sides of the adjusting seat 3. A return spring 8 is fixedly connected to the inner cavity of the adjusting seat 3, and a locking rod 9 is fixedly connected to the other end of the return spring 8. One end of the return spring 8 is fixedly connected to the bottom of the locking rod 9 and the inner side wall of the adjusting seat 3. An auxiliary slide plate 10 is sleeved on the outer ring surface of one end of the locking rod 9, and a toggle block 11 is fixedly installed on the outer surface of the auxiliary slide plate 10. A guide frame 12 is sleeved on the outer side of one end of the toggle block 11.

[0030] In use, when it is necessary to make the adjusting seat 3 move in an arc along the arc frame 2, firstly, move the lever 11. At this time, the levers 11, which are symmetrically arranged on one side of the adjusting seat 3, move towards each other along the guide frame 12 under the action of force. Then, as the levers 11 move laterally, the auxiliary slide plate 10 will cause the locking rod 9 to slide inside one end of the adjusting seat 3, thereby separating one end of the locking rod 9 from the arc frame 2. At the same time, as the locking rod 9 moves laterally, the locking rod 9 will squeeze the return spring 8, thereby deforming the return spring 8 and causing it to generate a reverse force. Then, when both locking rods 9 are separated from the arc frame 2, move the adjusting seat 3 so that it slides along the arc frame 2 through the guide block 7, thereby realizing the adjustment. The arc-shaped movement of the adjustment seat 3 facilitates subsequent adjustment of the tilt angle of the adjustment seat 3 according to actual practical needs. When the adjustment seat 3 moves to the appropriate position, the force applied to the lever 11 is released. At this time, the reverse force generated by the deformation of the return spring 8 will push the locking rod 9 in the opposite direction, thereby re-inputting one end of the locking rod 9 into the inner wall of the arc-shaped frame 2 to achieve the positioning of the adjustment seat 3. This facilitates subsequent pressure testing of the wheel hub at different tilt angles, resulting in greater flexibility and practicality. When the hydraulic cylinder 4 is working, it will drive the lifting seat 5 connected to its output end to move longitudinally, facilitating subsequent adjustment of the wheel hub position using the movement of the lifting seat 5, thereby enabling pressure testing.

[0031] like Figure 3 As shown, in some embodiments, a guide rod 13 is fixedly provided on one side of the top of the lifting seat 5. The guide rod 13 is symmetrically distributed along the vertical center line of the lifting seat 5. A drive motor 14 is fixedly provided on one side of the bottom of the side plate 6. The output end of the drive motor 14 is connected to a rotating seat 15. The drive motor 14 is electrically connected to an external controller through wires. The drive motor 14 is controlled to work by the electrical signal issued by the controller. A cylinder 16 is fixedly provided on the side wall of the side plate 6 on the other side of the bottom of the lifting seat 5. The output end of the cylinder 16 is connected to a clamping seat 17. The side walls of the rotating seat 15 and the clamping seat 17 are both equidistantly distributed with multiple friction pads along the center point to increase the friction between the cylinder and the hub. The clamping seat 17 is rotatably connected to the output end of the cylinder 16 through a bearing seat.

[0032] In use, the wheel hub is placed between the two side plates 6. At this time, the cylinder 16 works to push the clamping seat 17 connected to its output end laterally, thereby moving the clamping seat 17 to one side of the wheel hub. Then, in conjunction with the fixed rotating seat 15, it is convenient to perform subsequent clamping and limiting treatment on the wheel hub. When the drive motor 14 works, it will drive the rotating seat 15 connected to its output end to rotate. The rotation of the rotating seat 15 will realize the rotation of the clamped wheel hub, which will facilitate better subsequent testing of different positions of the wheel hub. It is worth noting that the side walls of the rotating seat 15 and the clamping seat 17 are provided with multiple through holes at equal intervals along the center point. These through holes facilitate the subsequent insertion of positioning pins. In conjunction with the rotating seat 15 and the clamping seat 17, it can further realize the stable installation of the wheel hub and ensure the stability of the wheel hub in the subsequent testing process. When the lifting seat 5 moves longitudinally, it is convenient to adjust the height of the wheel hub position, which will allow for better pressure testing. The guide rod 13 is used to improve the stability of the lifting seat 5 during longitudinal movement.

[0033] like Figure 5 As shown, in some embodiments, the inner sidewall of the arc frame 2 is provided with a guide rail 18, and the outer surface of the arc frame 2 is provided with a locking hole 19, the locking hole 19 and the arc frame 2 forming an integrated structure.

[0034] In use, the guide rail 18 can be used to guide the movement of the adjustment seat 3, so that the adjustment seat 3 can move in an arc along the arc frame 2. When one end of the locking rod 9 is inserted into the inside of the locking hole 19, the positioning of the adjustment seat 3 can be easily achieved.

[0035] like Figure 6 As shown, in some embodiments, a test platform 20 is fixed at the top center of the support 1, and a pressure sensor 21 is fixed at the top center of the cylinder 16. A lower pressure seat 22 is connected to the top of the pressure sensor 21, and a rubber pad 23 is fixed on the upper surface of the lower pressure seat 22. The rubber pads 23 are evenly distributed along the upper surface of the test platform 20, and the rubber pads 23 are made of rubber material.

[0036] During use, the bottom of the wheel hub to be tested will contact the upper surface of the test bench 20. At this time, the wheel hub will contact the rubber pad 23 in advance, and the rubber pad 23 will be used to prevent slipping. Then, as the wheel hub is pressed down, the test bench 20 will move longitudinally, which will facilitate the pressure sensor 21 to be pressed down by the test bench 20, so as to record and transmit the pressure data of the wheel hub.

[0037] like Figure 4 As shown, in some embodiments, the locking rod 9 is slidably connected to the adjusting seat 3 via the return spring 8, and the locking rod 9 is symmetrically distributed along the vertical center line of the adjusting seat 3;

[0038] When in use, the reverse force generated by the deformation of the return spring 8 will push the locking rod 9 in the opposite direction, thus facilitating the subsequent input of one end of the locking rod 9 into the lock hole 19.

[0039] like Figure 5 As shown, in some embodiments, the guide rail 18 is generally arc-shaped, and the locking holes 19 are equidistantly distributed along the inner side of the guide rail 18.

[0040] In use, since the guide rail 18 is arc-shaped, when the adjusting seat 3 drives the guide block 7 to move along the guide rail 18, it can make arc-shaped movements. The locking hole 19 facilitates the positioning of the adjusting seat 3 when the locking rod 9 is inserted into it.

[0041] In summary, during use, the hub is pre-clamped between the rotating seat 15 and the clamping seat 17 and fixed. Then, the lever 11 is moved, causing the two levers 11 to move towards each other along the guide frame 12. As the levers 11 move, the auxiliary slide plate 10 causes the locking rod 9 to slide inside one end of the adjusting seat 3, separating the locking rod 9 from the locking hole 19. At the same time, as the locking rod 9 moves laterally, the return spring 8 deforms and generates a reverse force. Then, when both locking rods 9 are separated from the locking hole 19, the adjusting seat 3 is moved, causing it to slide along the guide rail 18 via the guide block 7, thus achieving the arc-shaped movement of the adjusting seat 3. This facilitates subsequent adjustment of the tilt of the adjusting seat 3 according to actual practical needs. When the adjusting seat 3 moves to the appropriate position, the force applied to the lever 11 is released. At this time, the return spring 8 deforms and generates a reverse force. The force applied will push the locking rod 9 in the opposite direction, thereby re-entering one end of the locking rod 9 into the locking hole 19, realizing the positioning of the adjusting seat 3, which facilitates the subsequent pressure test of the wheel hub at different tilt angles. The overall design has higher flexibility and practicality. When the drive motor 14 is working, it will drive the rotating seat 15 connected to its output end to rotate, thereby using the rotation of the rotating seat 15 to realize the rotation of the clamped wheel hub, which facilitates the subsequent testing of different positions of the wheel hub. During the test, the bottom of the wheel hub to be tested will contact the upper surface of the test platform 20. At this time, the wheel hub will contact the rubber pad 23 in advance, which will be used to prevent slippage. Then, as the wheel hub is pressed down, the test platform 20 will move longitudinally, which will facilitate the pressure sensor 21 to be pressed down by the test platform 20, realizing the recording and transmission of the wheel hub pressure data.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
