Description

Technical Field

[0001] This utility model belongs to the field of shock absorber testing equipment, and relates to a comprehensive test bench for testing the performance of shock absorbers. Background Technology

[0002] Application CN201821915500.8 discloses a shock absorber performance test bench. This application describes a hydraulic rod that presses the shock absorber vertically downwards to test it. However, in practical applications, shock absorbers are subjected not only to vertical pressure but also to lateral forces. Therefore, this prior art cannot detect the changes that occur when a shock absorber is simultaneously subjected to vertical and lateral pressures. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a device that simulates actual working conditions by applying vertical and lateral pressure to a shock absorber. Furthermore, this device can further simulate the actual working conditions of the shock absorber when a car goes over potholes or turns, in order to test the performance of the shock absorber under complex conditions.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a comprehensive test bench for testing the performance of shock absorbers, comprising two columns, with a horizontal plate connected to the top of both columns. A first hydraulic rod is fixedly connected to the upper side of the horizontal plate, and a vertical movable plate is connected to the lower end of the first hydraulic rod. Vertical slides are fixedly connected to both ends of the vertical movable plate, and the vertical slides are slidably connected to the sides of the columns. A rotating seat is rotatably connected to the middle of the horizontal plate, and a positioning disk is coaxially connected to the rotating seat. The positioning disk is provided with a plurality of first positioning holes arranged in a ring. A second positioning hole is provided on the vertical movable plate corresponding to the first positioning holes. A second hydraulic rod is fixedly connected to the rotating seat. The second hydraulic rod includes a movable end, and a hinge seat is fixedly connected to the movable end. A shock absorber positioning seat is provided below the second hydraulic rod.

[0005] Preferably, two slide rails are slidably connected below the shock absorber positioning seat.

[0006] Preferably, a rack is provided between the two slide rails, a slide rod is slidably connected to the shock absorber positioning seat, and a toothed seat is connected to the lower end of the slide rod. The toothed seat slides up and down and is used to mesh with the rack.

[0007] Preferably, a spring is provided between the toothed seat and the shock absorber positioning seat, and the spring is sleeved on the slide rod.

[0008] Preferably, the system also includes a connecting rod, wherein through holes are provided in the middle and at both ends of the connecting rod.

[0009] Preferably, the connecting rod is slidably connected to a balance bar, the balance bar is U-shaped, and the balance bar is rotatably connected to a support.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] This invention is easy to adjust. When the shock absorber is hinged to the hinge seat and the shock absorber positioning seat, the tilt angle of the shock absorber can be changed by adjusting the height of the first hydraulic rod and the position of the shock absorber positioning seat. Furthermore, rotating the positioning plate can also adjust the direction of the output pressure of the first hydraulic rod.

[0012] This invention features a rack and pinion mechanism that meshes with a gear seat, and a sliding rod controls their engagement and disengagement, facilitating the positioning of the shock absorber. A connecting rod is also included, allowing the shock absorber to be hinged to the connecting rod, which in turn hinges to the hinge seat. A balance bar is inserted into the connecting rod, further simulating actual automotive conditions. Rotating the positioning disc applies pressure of varying angles and forces to the connecting rod, simulating the conditions during cornering. Therefore, this invention enables more realistic testing of the shock absorber, resulting in more reliable test results. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] like Figure 1 , Figure 2 As shown, a comprehensive test bench for testing the performance of shock absorbers includes two columns 1. A horizontal plate 2 is connected to the top of both columns 1. A first hydraulic rod 3 is fixedly connected to the upper side of the horizontal plate 2. A vertical movable plate 4 is connected to the lower end of the first hydraulic rod 3. Vertical slides 5 are fixedly connected to both ends of the vertical movable plate 4 and are slidably connected to the sides of the columns 1. A rotating seat 6 is rotatably connected to the middle of the horizontal plate 2, meaning the height of the rotating seat 6 can be adjusted by the first hydraulic rod 3. A positioning plate 7 is coaxially connected to the rotating seat 6, and the positioning plate 7 is equipped with several... The first positioning holes 8 are arranged in a ring. The vertical movable plate 4 is provided with a second positioning hole corresponding to the first positioning hole 8. Therefore, the rotating seat 6 can rotate. The rotating seat 6 is positioned by inserting bolts into the aligned first positioning hole 8 and second positioning hole. The rotating seat 6 is fixedly connected to a second hydraulic rod 9. The second hydraulic rod 9 includes a movable end. The movable end is fixedly connected to a hinge seat 10. A shock absorber positioning seat 11 is provided below the second hydraulic rod 9. Therefore, the two ends of the shock absorber 12 are hinged to the hinge seat 10 and the shock absorber positioning seat 11, respectively.

[0020] The method of using this utility model is as follows: By adjusting the height of the rotating seat 6, the rotation angle of the positioning plate 7, and the position of the shock absorber positioning seat 11, an angle is formed between the axial direction of the first hydraulic rod 3 and the axial direction of the shock absorber. Therefore, when the movable end moves, the shock absorber is subjected to pressure in both the vertical and horizontal directions.

[0021] To further simulate the actual working conditions of the shock absorber inside the vehicle.

[0022] Furthermore, two slide rails 13 are slidably connected below the shock absorber positioning seat 11, and the shock absorber positioning seat 11 moves linearly along the slide rails 13.

[0023] Furthermore, a rack 14 is provided between the two slide rails 13, and a slide rod 15 is slidably connected to the shock absorber positioning seat 11. The lower end of the slide rod 15 passes through the shock absorber positioning seat 11 and is connected to a toothed seat 16. The toothed seat 16 slides up and down and is used to mesh with the rack 14. Therefore, the shock absorber positioning seat 11 moves along the slide rail 13 to adjust its position and is positioned by meshing the toothed seat 16 and the rack 14.

[0024] Furthermore, a spring 17 is provided between the gear seat 16 and the shock absorber positioning seat 11, and the spring 17 is sleeved on the slide rod 15. The spring 17 pushes the gear seat 16 to mesh with the rack 14.

[0025] Furthermore, it also includes a connecting rod 18, which has through holes in the middle and at both ends. The middle part of the connecting rod 18 is used to hinge with the hinge seat 10, and the two ends are used to hinge with the shock absorber.

[0026] Furthermore, the connecting rod 18 is slidably connected to a stabilizer bar 19, which is the stabilizer bar 19 commonly found in automobiles. The stabilizer bar 19 is U-shaped and is rotatably connected to a support 20.

[0027] Usage: Rotate the positioning plate 7 and position it so that the second hydraulic rod 9 outputs vertical downward pressure or tilting pressure to simulate a car going over a pothole and a car turning, respectively. Then connect the hinge seat 10 and the connecting rod 18. The connecting rod 18 is connected to the two shock absorbers. Adjust the position of the shock absorber hinge seat 10 to control the tilt angle of the shock absorber. Adjust the position of the support 20 so that the two ends of the balance bar 19 are inserted into the vertical movable plate 4. Then fix the support 20 by bolt connection.

[0028] In addition, the shock absorber positioning seat is equipped with a pressure sensor for detecting the pressure on the shock absorber, which will not be described in detail here.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
