Simultaneously, various industry standards are imposing stricter requirements for the performance, safety, and reliability of electric vehicles, prompting continuous advancements and upgrades in testing technology. With the rapid development of the automotive industry, market demands for increasingly stringent performance, safety, and environmental performance are rising. To ensure that vehicles meet these high standards during design, production, and operation, whole-vehicle testing has emerged. However, during whole-vehicle testing, the rapid installation and removal of vehicles after testing remain difficult technical challenges. Addressing this issue not only improves testing efficiency but also directly impacts overall optimization and cost control of the testing process.

[0004] Therefore, those skilled in the art provide a plane adjustment device for supporting the axle system of a whole vehicle to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a plane adjustment device for the support of the entire vehicle shaft system. The device can effectively and quickly separate the vehicle wheel hub and the shaft system of the test bench, thereby realizing the rapid entry and evacuation of the car, greatly saving time and cost. In addition, the device can work in the laboratory, greatly improving the test safety.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a plane adjustment device for supporting the shaft system of a whole vehicle, comprising a base plate, a support slide plate slidably provided on one side of the upper end of the base plate and fixed by a plurality of bolts, a torque meter bearing seat support 2 and a support component 1 fixedly provided on both sides of the upper end surface of the support slide plate, and a DC suction cup type electromagnet fixedly provided on the front and rear ends of the torque meter bearing seat support 2 and the lower portion of the support component;

[0013] The utility model has the following beneficial effects:

[0014] The present invention proposes a plane adjustment device for supporting the shaft system of a whole vehicle. The ball coupling of the present invention is connected to the torque meter through coupling 2, and one end of the torque meter is connected to the test bench through coupling 1. This design allows for fast and safe disconnection and connection between the vehicle wheel hub and the shaft system of the test bench, and realizes the function of quickly separating the vehicle wheel hub and the shaft system of the test bench, which enables the car to enter the site quickly before the test and evacuate quickly after the test is completed. This advantage greatly saves time cost and improves test efficiency in actual operation, which is especially important for vehicles that require frequent testing, such as electric vehicles. The device is designed to work in a test room, which not only ensures the controllability of the test environment, but also greatly improves the safety of the test during operation.

The key is that the utility model matches the front and rear wheel tracks of different vehicles by adjusting the position of the plane adjustment device. The device can adapt to the testing needs of various models, including but not limited to different wheelbases and track configurations. This flexibility ensures the wide applicability and practicality of the device. During the body straightening process, the vehicle remains in the started state and provides power. The wheels are pressed on the rollers that are always consistent with the center line of the shaft system. Gravity and friction cause the rollers to move, and then the wheels are automatically returned to the center. This feature simplifies the operating process, reduces the need for manual intervention, and also ensures the accuracy of the test. The utility model can move the two sides of the roller component to a position that can support the wheel as needed to ensure that the wheel is suspended. This design realizes the simultaneous opposite movement of the rollers on both sides through the component connecting plate, which can always maintain the consistency of the center line and the shaft system, ensuring the stability of the vehicle and the accuracy of positioning during the test.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figures 1-4 The present invention provides an embodiment of a plane adjustment device for supporting a vehicle shaft system, comprising a base plate 1, a support slide 19 being slidably provided on one side of the upper end of the base plate 1 and fixed by a plurality of bolts, a torque meter bearing seat support 2 4 and a support component 1 9 being fixedly provided on both sides of the upper end surface of the support slide 19, and a DC suction cup type electromagnet 12 being fixedly provided at the front and rear ends of the lower portions of the torque meter bearing seat support 2 4 and the support component 1 9;

[0023] A bearing seat 5 is fixedly provided on the upper end of the torque meter bearing seat support 2 4, and a torque meter 3 is provided inside the bearing seat 5 through a bearing fixing sleeve. The end of the torque meter 3 close to the support component 1 9 is fixedly connected to a ball coupling 10 through a coupling 2 7, and one end of the ball coupling 10 is connected to a connecting plate 15 through an adapter plate 13.

[0024] A screw machine 17 is fixedly mounted at the center of the side of support component 19 facing away from torque meter bearing support 24. A guide bar 8 is fixed to the upper end of support component 19 via multiple bolts. Support component 2 11 is fixedly mounted on the guide bars 8 at the front and rear ends of screw machine 17. A screw 6 is connected to support component 19 on the side of screw machine 17 near torque meter bearing support 24. A screw 14 is mounted between the two support components 11, and a support surface 18 is fixedly mounted at the upper end between the two support components 11. The upper portions of screw 14, near both the front and rear ends, pass through support surface 18 and extend to the upper end of support surface 18, where a roller component 16 is fixedly mounted via bolts. A coupling 2 is fixedly connected to the end of torque meter 3 facing away from support component 19. The main function of the lead screw 6 is to adjust the position of the support slide 19 on the base plate 1 through the drive of the lead screw machine 17, which helps to quickly align and position according to the front and rear wheel tracks of the vehicle under test. By adjusting the position of the support slide 19, the lead screw 6 can ensure that the torque meter bearing seat support 24 and the shaft system on the support component 19 are aligned with the wheels of the vehicle under test, ensuring the accuracy and stability of the test. When the lead screw 6 rotates, it cooperates with the nut on the support slide 19 to make the support slide 19 slide along the set guide rail on the base plate 1. When the support slide 19 is adjusted to the appropriate position, it can be fixed by multiple bolts to ensure that no displacement occurs during the test, thereby ensuring the reliability of the test. The main function of lead screw 2 14 is to drive the roller components 16 on both sides to move in opposite directions through its rotational motion, so that the roller components 16 can lift the wheel and ensure that the wheel is suspended. At the same time, the design of lead screw 2 14 ensures that the center line of the roller components 16 on both sides is always consistent with the center line of the shaft system, which helps to maintain the stability and accurate positioning of the wheel during testing. When lead screw 2 14 rotates, it cooperates with the nut on the roller component 16 to move the two roller components 16 in opposite directions on the support surface 18. Regardless of the specific position of the wheel, the roller components 16 on both sides can move toward the center simultaneously to lift the wheel. Once the roller components 16 are adjusted to the appropriate position and lift the wheel, they can be fixed with bolts to ensure that the roller components 16 do not move during testing, maintaining a stable and suspended state of the wheel. Through precise mechanical design and a coordinated drive system, these two lead screws jointly achieve rapid separation and connection between the vehicle wheel hub and the test bench shaft system, improving the efficiency and safety of vehicle testing.

[0025] Specifically, it is primarily used in scenarios requiring shaft support or wheel support for testing powertrains, suspension systems, and vehicle dynamic performance. This device effectively addresses the challenges of rapid vehicle installation and removal during vehicle testing. The splined design of the ball coupling 10 enables quick disconnection and connection between the wheel and shaft, significantly reducing installation and removal time, enabling rapid vehicle entry and exit. Furthermore, during vehicle alignment, the roller component 16 automatically aligns the vehicle body and wheels, reducing manual adjustments and improving operational convenience and test accuracy. The wheel suspension function, supported by the roller component 16, ensures vehicle stability and safety during testing. The multi-level support structure, including the base plate 1, support slide 19, support component 1 9, and support component 2 11, provides reliable mechanical support and enhances the stability of the device. The device operates within a test chamber, enhancing testing safety. Furthermore, after shaft installation is complete, the roller component 16 moves toward the center, holding the wheel and preventing the vehicle from sliding out during testing, further enhancing safety. During the specific implementation process, after the vehicle body is tilted into the test site, the position of the plane adjustment device is adjusted according to the front and rear wheel tracks of the vehicle being tested. The wheels are suspended in the air by moving the two sides of the roller component 16. The vehicle is then started and deceleration power is provided to make the tire fit the roller. The front wheel is observed to see if it fits and necessary adjustments are made. Finally, the roller component 16 is removed to allow the wheel to fall onto the support surface 18, completing the installation of the shaft system. After the test is completed, the spline design of the ball coupling 10 allows for quick disengagement, reducing installation time on the test bench and allowing the vehicle to be quickly withdrawn. In short, this invention not only improves the efficiency and accuracy of vehicle testing, but also significantly enhances the safety of the testing process and the convenience of operation.

[0026] Working principle: After the vehicle body tilts into the field, first adjust the position of the plane adjustment device according to the front and rear wheelbase of the vehicle to be tested, and align the front and rear wheels, that is, the vehicle body and the wheels are parallel, and the roller components 16 move on both sides. The roller components 16 on both sides can be moved in opposite directions at the same time through the screw 2 14, and the center lines and shaft systems of the roller components 16 on both sides are always kept on the same center line until the wheels can be lifted and the vehicle is suspended in the air. Start the car without turning, and give the vehicle a slow-down power so that the tires slowly fit with the roller components 16 by relying on the rotational force. When the rear wheels fit with the roller components 16, stop supplying power to the vehicle. At this time, observe whether the front wheel fits with the roller component 16. If so, the vehicle is parallel to the shaft system. If not, lightly turn the steering wheel or the artificial board to align the front wheel, remove the roller component 16, the amplitude should not be too large, so that the wheel falls smoothly on the supporting surface 18, and install the shaft system. After the shaft system is installed, the roller component 16 moves to the middle and holds the wheel so that the vehicle will not rush out during the test, thereby completing the vehicle installation. When the test is completed or the vehicle needs to be quickly withdrawn, the ball coupling 10 is in the form of a spline, which can realize the rapid disengagement of the wheel hub and the shaft system, thereby reducing the installation time on the test bench and allowing the vehicle to be quickly withdrawn.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
