Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to an active lateral stabilizer bar testing device. Background Technology

[0002] With the rapid development of the automotive industry, the requirements for vehicle stability and handling are increasing. Active stabilizer bars, which effectively improve vehicle dynamics, are widely used. Active stabilizer bars reduce body roll by adjusting the vehicle's lateral stability in real time, thereby enhancing driving comfort and safety.

[0003] However, existing active stabilizer bar testing equipment has several shortcomings in practical applications. First, the testing accuracy of existing equipment is often insufficient, failing to realistically simulate various complex driving conditions, which reduces the reliability of test results. Second, the operation of many testing devices is relatively complex, increasing testing time costs and potentially introducing human error, affecting the accuracy of test results. Furthermore, existing equipment has poor adaptability, making it difficult to meet the testing needs of different specifications and types of active stabilizers, thus limiting its use. Simultaneously, many traditional testing devices can only perform static tests, lacking a comprehensive evaluation of stabilizer bar performance under dynamic conditions, and failing to meet the real-time performance monitoring needs of modern vehicles.

[0004] Therefore, a new detection device is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an active lateral stabilizer bar testing device, which aims to solve the problems of insufficient testing accuracy, poor adaptability, and limited testing conditions of traditional testing devices.

The cross slide 1 is mounted on the top of the frame 10, the load spring 2 is mounted on the side of the cross slide 1 away from the frame 10, the linear drive connecting rod 3 is mounted on the side of the load spring 2, the linear displacement sensor 4 and the pressure sensor 11 are respectively mounted on the linear drive connecting rod 3, the linear drive support platform 9 is disposed at the bottom of the linear drive connecting rod 3, the support platform 7 is fixedly connected to the frame 10 and located on the top of the frame 10, the active lateral stabilizer bar 5 is mounted on the top of the support platform 7, the motor 6 is fixedly connected to the support platform 7 and located on the side of the support platform 7 away from the frame 10, and the drive linkage 8 is mounted between the output end of the motor 6 and the active lateral stabilizer bar 5.

[0020] In this embodiment, the cross slide 1 is mounted on the frame 10, serving as the basic support structure for the entire device, ensuring its stability and providing adjustable sliding functionality. The load spring 2 is fixed between the cross slide 1 and the linear drive connecting rod 3, providing elastic support and transmitting the applied external force. One end of the linear drive connecting rod 3 is connected to the load spring 2, and the other end is connected to the linear displacement sensor 4 and the pressure sensor 11. The pressure sensor 11 employs an S-shaped shear beam structure (range 0-5T, accuracy ±0.03%FS, model ZL-3A) to monitor the force on the active lateral stabilizer 5 in real time and transmit the applied force. Data feedback indicates that the linear displacement sensor 4 uses a wire encoder (range 0-500mm, resolution 0.01mm, IP68 protection) to measure the displacement of the linear drive connecting rod 3, ensuring precise control of the equipment. The active lateral stabilizer 5 to be tested is mounted on the support platform 7 and connected to the motor 6 via the drive connecting rod 8. The motor 6 provides the necessary driving force, enabling the drive connecting rod 8 to transmit rotational motion to the active lateral stabilizer 5 under test, thus facilitating stability testing. Simultaneously, the linear drive support platform 9 and the frame 10 serve as fixed support structures, ensuring the stability of the equipment during operation. The entire device, through real-time monitoring and adjustment, can efficiently and accurately evaluate the performance and stability of the active lateral stabilizer bar 5. By optimizing the structure of the testing device and the testing method, the device simplifies the testing operation steps, specifically including: (1) Test position adjustment: The position of the slide platform 12 can be directly adjusted by rotating the upper handwheel 14 and the lower handwheel 16, eliminating the need for disassembly and assembly of positioning fixtures in traditional equipment; (2) Specification assembly: The spring washer 19 can be detached and replaced to compensate for displacement of the cross slide 1, eliminating the need for special fixtures to replace stabilizers of different specifications; (3) Test mode switching: The motor 6 is linked with the linear displacement sensor 4 and the pressure sensor 11 for control, eliminating the need for mode switching operations in static / dynamic testing. This improves testing efficiency, reduces the complexity of manual intervention, and enables high-precision testing of the active lateral stabilizer bar, avoiding measurement deviations caused by equipment errors or method limitations in traditional technologies. The active lateral stabilizer bar is applicable to various specifications and models, overcoming the problems of strong specificity and poor versatility in existing technologies: through the ±50mm bidirectional displacement adjustment range of the cross slide 1, the three-stage replaceable spring washer 19 of the load spring 2 (thickness 5 / 10 / 15mm), and the ±15° hinge angle adaptive structure of the drive link 8, the device can adapt to the active lateral stabilizer bar 5 with a bar diameter of 12-30mm and a torque range of 500-3000N·m, covering the specifications of 90% of passenger cars and light commercial vehicles.It supports various test conditions, including static and dynamic tests, and can comprehensively evaluate the performance of the active lateral stabilizer bar under complex conditions, solving the problems of insufficient detection accuracy, poor adaptability and single test conditions of traditional testing equipment.

[0022] In this embodiment, by rotating the upper handwheel 14 and the lower handwheel 16, the upper slide groove 13 can be driven to move along the first horizontal direction. By rotating the lower handwheel 16, the lower slide groove 15 can be driven to move along the second horizontal direction perpendicular to the first direction. The upper slide groove 13 and the lower slide groove 15 are slidably engaged by a dovetail groove structure, so that the slide platform 12 can achieve bidirectional precision displacement adjustment in the horizontal plane, meeting the positional accuracy requirements of the cross slide 1 in different testing scenarios.

[0023] Furthermore, the load spring 2 includes a spring 17, a housing 18, a spring washer 19, a bracket 20, and a cross member 21.

The cross member 21 is disposed on one side of the housing 18.

[0024] In this embodiment, the external load is applied to the load spring 2 through the cross member 21. Specifically, the spring 17 undergoes elastic deformation, converting the external force into an elastic restoring force, which is then transmitted to other components through the cross member 21. The spring washer 19 effectively buffers the contact stress between the spring 17 and the housing 18, while the bracket 20 provides support for the housing 18, forming a complete force transmission and buffering mechanism together with the housing 18.

The first linear drive rod 23 and the second linear drive rod 24 are fixedly connected to the connecting rod body 22 and connected to the linear displacement sensor 4 through the connector 25. The second linear drive rod 24 is connected to the connector 25 and the pressure sensor 11.
