Description

Technical Field

[0001] The present invention relates to a vehicle axle detection technology, and in particular to a vehicle axle balance detection device. Background Art

[0002] An automobile axle (also known as the axle) is connected to the vehicle frame (or monocoque) through a suspension system, with wheels mounted at each end. The axle's function is to bear the vehicle's load and maintain smooth driving on the road. Axles can be integral, like a giant barbell, with the vehicle body supported by a suspension system at both ends. Integral axles are typically used with non-independent suspension systems. Alternatively, axles can be disconnected, like two umbrellas inserted on either side of the vehicle body, each supported by a suspension system. Disconnected axles are used with independent suspension systems. The axle's crucial role requires ensuring good balance, which is why simulations of axle motion are used to test its balance.

[0003] A Chinese invention patent with publication number CN118857557B discloses a factory-based balance detection device for automobile axle assemblies. The factory-based balance detection device utilizes a turntable during steering to abut the outer side of the wheel disc, and rotates the motor in the transmission box to clamp and rotate the two sides of the wheel disc, simulating the movement of the wheel discs on both sides of the axle, and performing a toe-in value deflection trend detection on the axle. A secondary toe-in value calibration and adjustment is performed through the tightening adjustment mechanism on the slide, thereby extending the toe-in adjustment time for subsequent axle-assembled vehicles and ensuring the balance and stability of the entire axle assembly before leaving the factory. At the same time, when performing the axle toe-in value deflection trend detection, the toe-in value obtained in the early stage can also be verified to ensure the normal operation of the tie rods and angle sensors on the entire axle, thereby playing a reverse verification role.

[0004] When using existing equipment, it is impossible to perform axle balance detection at different levels, and thus it is impossible to accurately understand whether the axle will be affected by imbalance due to ground tilt or level changes. At the same time, before the detection process, when assembling the axle, slight deviations are prone to occur at the docking points at both ends of the axle, resulting in inaccurate axle installation, which in turn affects the stability of the axle detection. Therefore, an axle balance detection device has been developed. Summary of the Invention

[0033] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, unless otherwise expressly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium, or they can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Example: See Figures 1-8 A vehicle axle balance detection device includes a base 1, a positioning column 11 is fixedly installed on the upper end of the base 1, and a telescopic member 12 is fixedly installed on the end of the base 1 and on one side of the positioning column 11. The output end of the telescopic member 12 is fixedly installed with an adjustment component 2, and the vehicle axle is positioned by the adjustment component 2.

[0036] In this solution, the inner wall of positioning column 11 is equipped with a telescopic device, such as an electric telescopic rod, which is connected to an external control device. Positioning column 11 is used to adjust the height of the axle during assembly. Telescopic member 12 is also used to adjust the position of adjustment assembly 2, making it suitable for different scenarios.

[0037] Furthermore, the movable component 3 is assembled at the end of the adjusting component 2, and the axle is corrected and limited by the movable component 3, and the angle of the axle is adjusted in cooperation with the adjusting component 2; wherein, the movable component 3 includes a docking plate 31, and a fixed plate 32 is rotatably mounted on the upper end of the docking plate 31, and a power part 321 is fixedly mounted on the end of the fixed plate 32, and a positioning plate 33 is fixedly mounted on the end of the fixed plate 32 away from the power part 321, and the output end of the power part 321 passes through and extends to the outside of the positioning plate 33.

[0038] In this embodiment, the power member 321 is a device with power output, such as a motor, and is connected to an external control device. When the power member 321 is started, it synchronously drives the turntable 35 provided at its output end to rotate.

[0039] A device with power output, such as a motor, is fixedly mounted on the end of the docking plate 31 , and the motor drives the fixed plate 32 to rotate until it reaches an optimal position and stops.

[0040] Furthermore, multiple groups of slide grooves 331 are opened on the outer surface of the positioning plate 33, and the multiple groups of slide grooves 331 are evenly distributed at the end of the positioning plate 33. A slider 34 is slidably installed inside the slide groove 331, and a turntable 35 is fixedly installed on the output end of the power part 321. A rotating rod 351 corresponding to the slider 34 is rotatably installed on the outer surface of the turntable 35, and the end of the rotating rod 351 is rotatably connected to the end of the slider 34.

[0041] Specifically, when the turntable 35 rotates, it synchronously drives the rotating rod 351 installed on its outer surface to rotate, and when the rotating rod 351 rotates, it drives the slider 34 installed on the end of the rotating rod 351 to move, wherein the outer surface of the slider 34 is slidably installed with the inner wall of the slide groove 331, thereby ensuring that the slider 34 remains stable as a whole when moving.

[0042] Furthermore, an arc-shaped plate 332 corresponding to the slider 34 is fixedly mounted on the end of the positioning plate 33 , and a locking block 341 is slidably mounted on the end of the arc-shaped plate 332 . The end of the locking block 341 is fixedly connected to the end of the slider 34 .

[0043] Specifically, a movable groove is provided at the end of the arc-shaped plate 332, and the inner wall of the movable groove is slidably connected to the outer surface of the locking block 341. At the same time, the end of the locking block 341 passes through and extends to the other end of the arc-shaped plate 332. Since the end of the locking block 341 is fixedly connected to the end of the slider 34, when the slider 34 moves, the locking block 341 is synchronously driven to move to lock the corrected axle end.

[0044] Furthermore, a power rod 36 is fixedly mounted on the end of the turntable 35 , a power block 361 is fixedly mounted on the end of the power rod 36 , and a guide block 38 is rotatably mounted on the end of the power block 361 .

[0045] Specifically, when the turntable 35 rotates, the power rod 36 is driven to rotate. Since the power block 361 is fixedly installed at the end of the power rod 36, when the power block 361 rotates, the guide block 38 installed at the end of the power block 361 is synchronously driven to move, wherein the end of the guide block 38 is spherical.

[0046] Furthermore, a disc 37 is rotatably mounted on the power rod 36. The end of the disc 37 is fixedly connected to the end of the positioning plate 33. A guide rail 371 is fixedly mounted on the end of the disc 37 near the power block 361. The cross-section of the guide rail 371 is arc-shaped. The inner wall of the guide rail 371 is slidably connected to the outer surface of the guide block 38, and the outer surface of the guide block 38 is embedded in the inner wall of the guide rail 371. A detection block 381 is rotatably mounted at the connection between the guide block 38 and the power block 361.

[0047] Specifically, the unfolded state of the guide rail 371 is trapezoidal, and when the outer surface of the guide block 38 is in contact with the inner wall of the guide rail 371, it is tightly embedded in the inner wall of the guide rail 371 and moves along the inner wall of the guide rail 371. At the same time, when the guide block 38 is moved by force, it moves along the inner wall of the guide rail 371, and at the same time drives the guide block 38 to rotate along the end of the power block 361.

[0048] When the guide block 38 is forced to move and rotate along the power block 361, it simultaneously drives the detection block 381 mounted at the connection between the guide block 38 and the power block 361. Torsion springs are mounted on the ends of the detection block 381 and the power block 361, which relieve the contact between the detection block 381 and the outer surface of the axle. The ends of the detection block 381 are equipped with angle-adjustable components such as laser sensors, which detect the axle assembly position and angle.

[0049] Furthermore, support plates 39 are symmetrically fixedly mounted on the ends of the docking plates 31 , and the axle is preliminarily supported by the support plates 39 .

[0050] Specifically, the inner wall of the support plate 39 is provided with a device with telescopic function such as an electric telescopic rod, and is connected to an external control device. At the same time, an arc-shaped locking plate is provided at the end of the support plate 39. By adjusting the position of the arc-shaped locking plate, the axle can be adjusted in conjunction with the detection block 381 when the axle is assembled, which is convenient for subsequent locking.

[0051] Correction locking ensures that the relative position and angle between the equipment and the axle remain consistent during the inspection process, avoiding possible errors caused by the equipment and effectively preventing external environmental factors from interfering with the inspection results.

[0052] Furthermore, the adjustment assembly 2 includes a movable plate 21 slidably connected to the base 1. A driving member 22 is fixedly mounted on the end of the movable plate 21, and a driving disc 23 is fixedly mounted on the output end of the driving member 22. A driving rod 24 is rotatably mounted on the end of the driving disc 23 near the edge. A movable plate 25 is rotatably mounted on the end of the driving rod 24, and a rotating block 26 is rotatably mounted on the end of the movable plate 25.

[0053] In this embodiment, the driving member 22 is a device with a power output, such as a motor, and is connected to an external control device. When the driving member 22 is activated, it synchronously drives the driving disc 23 disposed at its output end to rotate. As the end of the driving disc 23 is mounted with a driving rod 24, the driving rod 24 is driven to rotate. The cross-section of the movable plate 21 is L-shaped.

[0054] When the driving rod 24 rotates, it synchronously drives the movable plate 25 installed at its end to rotate, wherein the rotating block 26 is rotatably installed at the end of the movable plate 21, and the end of the rotating block 26 is fixedly connected to the end of the movable plate 25, so that when the movable plate 25 is subjected to force, the rotating block 26 is driven to rotate along the connection of the movable plate 21.

[0055] Furthermore, the end of the rotating block 26 extends through and to the other end of the movable plate 21. A limit rod 28 is fixedly mounted on each end of the rotating block 26. A protective ring 27 is fixedly mounted on the end of the movable plate 21. The inner wall of the protective ring 27 defines an annular groove 271, which is slidably connected to the outer surface of the end of the limit rod 28.

[0056] Specifically, when the rotating block 26 rotates, it simultaneously drives the limiting rods 28 fixedly mounted at both ends thereof to move, and limits the limiting rods 28 through the annular grooves 271 to ensure the stability of the rotation of the limiting rods 28 .

[0057] Furthermore, a telescopic rod 29 is fixedly installed on the end of the rotating block 26, and a moving block 281 is slidably installed on the outer surface of the limiting rod 28, and the end of the moving block 281 is connected to the end of the telescopic rod 29, and a support plate 282 is fixedly installed on the end of the moving block 281, and the end of the support plate 282 is fixedly connected to the end of the docking plate 31.

[0058] Specifically, the telescopic rod 29 is a device with a telescopic function, such as an electric telescopic rod, and is connected to an external control device. When the telescopic rod 29 is started, it drives the moving block 281 set at its output end to move. At the same time, the inner wall of the moving block 281 is slidably connected to the outer surface of the limit rod 28, so that the moving block 281 remains stable as a whole during movement, and at the same time drives the support plate 282 to move.

[0059] The entire movable assembly 3 is supported by support plate 282, allowing it to adjust accordingly to simulate different scenarios. Testing the axle balance at different levels simulates the vehicle's performance on various complex terrains, ensuring that the test results are closer to actual use. Testing at different levels also verifies the axle's performance on uneven ground or slopes, ensuring that the axle maintains good balance in various terrain conditions.

[0060] At the same time, multiple sensors are installed near the axle and the axle itself, including distance sensors and laser sensors for detecting various data of the axle. At the same time, sensors are set on the outer surfaces of the movable component 3 and the adjustment component 2 to detect various data of the axle and transmit the detected data to the storage for collection.

[0061] The control device can use a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (MCU), consisting of an arithmetic unit, a controller, memory, and input / output devices, equivalent to a miniature computer. Compared to the general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its greatest advantages are its small size, allowing it to be placed inside the instrument, low memory capacity, simple input / output interfaces, and low functional consumption.

[0062] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
