Description

Technical Field

[0001] The utility model relates to a torque converter testing device, in particular to a performance testing device for a torque converter. Background Art

[0002] Torque converter (also known as real-time four-wheel drive system) is an intelligent driving technology developed in recent years. The system is managed by the electronic control unit (ECU). By monitoring the vehicle's driving status in real time, it automatically switches between two-wheel drive (2WD) and four-wheel drive (4WD) modes according to different road conditions, thereby ensuring power and passability while improving fuel economy. On bumpy roads, roads with many slopes and bends, or in environments with low adhesion, the system can automatically set itself to four-wheel drive mode to enhance traction and stability; while on flat urban roads, it switches to two-wheel drive mode to reduce fuel consumption.

[0003] At present, there are many torque converter products on the market, but there are still certain technical defects in their performance testing process. When detecting the side slip noise problem of the torque converter, the existing testing equipment cannot effectively screen out unqualified products that may produce abnormal noise in actual use, resulting in some products entering the market without strict quality control, thus affecting user experience and product reliability. In addition, product positioning before testing is relatively cumbersome, and usually requires manual adjustment of the position of the test workpiece, which is not only time-consuming, but also reduces the overall test efficiency. Therefore, there is an urgent need for an improved torque converter performance testing equipment to improve the accuracy and efficiency of the test, ensure product quality, and optimize the test process.

[0022] like Figure 1 As shown, the utility model provides a technical solution: a performance test device for a torque converter, comprising:

[0023] A bottom plate 1, a driving motor 9 is arranged on one side of the top of the bottom plate 1, a magnetic powder brake 6 is arranged on the other side of the top of the bottom plate 1, a support seat 4 and a mounting seat 2 are arranged on the top of the bottom plate 1 in sequence, a torque sensor 5 connected to the output shaft of the magnetic powder brake 6 is arranged on the top of the support seat 4, a placement seat 3 for placing a torque converter product 7 is arranged on the top of the mounting seat 2, a detection shaft of the torque sensor 5 passes through the placement seat 3 and is connected to the output shaft of the torque converter product 7, a positioning plate 8 is arranged on the output shaft of the driving motor 9, a plurality of positioning columns 711 connected to the positioning seat 71 on the output shaft of the torque converter product 7 and positioning holes 81 matching the output shaft of the torque converter product 7 are opened on the positioning plate 8, a moving component 10 for driving the driving motor 9 to move horizontally is arranged on the top of the bottom plate 1, a support plate 11 placed directly below the torque converter product 7 is arranged on the side wall of the placement seat 3, and a noise sensor 12 for detecting abnormal noise of the torque converter product 7 is arranged on the top of the support plate 11. This design The moving assembly 10 is used to drive the driving motor 9 to move laterally. The driving motor 9 moves to drive the positioning hole 81 on the positioning plate 8 to connect with the positioning column 711 connected to the positioning seat 71 on the output shaft of the torque converter product 7. Then, the driving motor 9 is operated to drive the positioning plate 8 to rotate. The rotation of the positioning plate 8 drives the positioning column 711 to rotate under the action of the positioning hole 81. The rotation of the positioning column 711 drives the positioning seat 71 to rotate. The rotation of the positioning seat 71 drives the output shaft of the torque converter product 7 to rotate. Then, the magnetic powder brake 6 is energized. The friction force generated by the attraction of the electromagnetic coil inside the magnetic powder brake 6 and the torque converter product 7 can drive the terminal magnetic powder brake 6 to rotate together, so that the magnetic powder brake 6 is detected and adjusted by the torque sensor 5 to reach the peak torque, that is, the braking load is greater than the load of the product. At this time, the product slips. If the noise sensor 12 cannot detect abnormal noise when slipping, it means that the product is qualified. If abnormal noise is detected, it means that the product is unqualified, which plays a role in facilitating the identification of unqualified products.

[0024] Reference Figure 1 and Figure 3 A mounting groove 21 is provided on one side of the top of the mounting seat 2 near the positioning plate 8, a placement seat 3 is provided inside the mounting groove 21, a fixing bolt 32 is provided between the placement seat 3 and the mounting seat 2, a mounting bolt 31 is provided between the placement seat 3 and the torque converter product 7, a spline is provided between the output shaft of the torque converter product 7 and the detection shaft of the torque sensor 5, and this design facilitates the installation of the torque converter product 7 on the side wall of the placement seat 3 by using the mounting bolt 31. At this time, the output shaft of the torque converter product 7 and the detection shaft of the torque sensor 5 are connected by a spline, thereby facilitating the positioning of the product, saving positioning time, and thereby improving the efficiency of the test, and the detection shaft of the torque sensor 5 and the output shaft of the magnetic powder brake 6 are connected by a spline.

[0025] Reference Figure 1 and Figure 4 The moving assembly 10 includes a fixed plate 101 arranged at the bottom of the driving motor 9, a pair of first slide rails 103 connected to the fixed plate 101 are arranged at the top of the bottom plate 1, a nut seat 104 is arranged at the bottom of the fixed plate 101, a pair of connecting plates 106 arranged between the pair of first slide rails 103 are arranged at the top of the bottom plate 1, a screw rod 105 connected to the nut seat 104 is arranged between the pair of connecting plates 106, a connecting plate 107 is arranged on the side wall of the bottom plate 1, and an output motor connected to the screw rod 105 is arranged on the side wall of the connecting plate 107 102. The design drives the screw rod 105 to rotate by operating the output motor 102. The screw rod 105 rotates and drives the fixing plate 101 to move laterally under the action of the nut seat 104 and the first slide rail 103. The fixing plate 101 moves laterally and drives the driving motor 9 to move laterally. The driving motor 9 drives the positioning hole 81 on the positioning plate 8 to connect with the positioning column 711 connected to the positioning seat 71 on the output shaft of the torque converter product 7. The side wall of the screw rod 105 inserted into the connecting plate 106 is a smooth surface, which improves the rationality of the design.

[0026] Reference Figure 2 The positioning seat 71 is in the shape of an equilateral triangle, and the corners of the side wall of the positioning seat 71 are provided with rounded corners. The side wall of the positioning seat 71 is provided with an arc-shaped groove recessed inwardly. There are three positioning posts 711, and the three positioning posts 711 are evenly distributed at the corners of the positioning seat 71. There are four positioning holes 81, three of which correspond to the three positioning posts 711 one by one, and the other positioning hole 81 corresponds to the output shaft of the torque converter product 7. This design facilitates the connection between the positioning posts 711, the output shaft of the torque converter product 7 and the positioning holes 81 on the positioning plate 8.

[0027] Reference Figure 2 and Figure 3 A second slide rail 14 is horizontally arranged on the top of the bottom plate 1, and an adjustment plate 13 that fits with the side of the positioning seat 71 is arranged on the slider of the second slide rail 14. This design uses the second slide rail 14 to make the adjustment plate 13 move horizontally and fit with the side of the positioning seat 71, thereby stopping the position of the positioning column 711, making it convenient for the driving motor 9 to drive the positioning hole 81 on its positioning plate 8 to be positioned and connected with the positioning column 711, thereby accelerating the positioning speed, thereby further facilitating the positioning of the product, saving positioning time, and thus improving the efficiency of the test. After the positioning connection is completed, the adjustment plate 13 is moved to a suitable avoidance position under the action of the second slide rail 14 to avoid interference between the positioning seat 71 and the moving plate during rotation.

[0028] Reference Figure 3 A support frame 15 is provided at the bottom of the base plate 1, and this design improves the stability of the detection.

[0029] Reference Figure 1-Figure 4As an embodiment of the utility model: when the performance of the torque converter product 7 needs to be tested, the staff can easily install the torque converter product 7 on the side wall of the placement seat 3 by using the mounting bolts 31. At this time, the output shaft of the torque converter product 7 and the detection shaft of the torque sensor 5 are connected by splines, so as to facilitate the positioning of the product, save positioning time, and thus improve the efficiency of the test. Then, the adjustment plate 13 is pushed to move laterally along the second slide rail 14, so that the side wall of the adjustment plate 13 fits with the side wall of the positioning seat 71, and then the output motor 102 in the moving assembly 10 is driven to drive the screw rod 105 to rotate. The screw rod 105 rotates to drive the nut seat 104 to rotate, and under the action of the limit of the first slide rail 103, the drive motor 9 moves horizontally. The drive motor 9 moves to drive the positioning hole 81 on the positioning plate 8 to connect with the positioning column 711 connected to the positioning seat 71 on the output shaft of the torque converter product 7, and then pushes the adjustment plate 13 to move horizontally along the second slide rail 14, so that the side wall of the adjustment plate 13 is separated from the side wall of the positioning seat 71, avoiding interference when the subsequent positioning seat 71 rotates, thereby completing the positioning drive connection of the torque converter product 7, facilitating the positioning of the product, saving positioning time, and thus improving the efficiency of the test.

[0030] After the positioning drive connection is completed, the drive motor 9 is operated to drive the positioning plate 8 to rotate. The rotation of the positioning plate 8 drives the positioning column 711 to rotate under the action of the positioning hole 81. The rotation of the positioning column 711 drives the positioning seat 71 to rotate. The rotation of the positioning seat 71 drives the output shaft of the torque converter product 7 to rotate. Then, the magnetic powder brake 6 is energized. The friction force generated by the attraction of the electromagnetic coil inside the magnetic powder brake 6 and the torque converter product 7 can drive the end magnetic powder brake 6 to rotate together, so that the magnetic powder brake 6 is detected and adjusted by the torque sensor 5 to reach the peak torque, that is, the braking load is greater than the load of the product. At this time, the product slips sideways. If the noise sensor 12 cannot detect abnormal noise when slipping, it means that the product is qualified. If abnormal noise is detected, it means that the product is unqualified, thereby facilitating the identification of unqualified products and improving the practicality of the utility model.
