Description

Technical Field

[0001] This application relates to the technical field of automotive chassis, and particularly to a fatigue test device for simulating road tests of automotive chassis. Background Art

[0002] The automotive chassis is composed of four parts: the powertrain, the running gear, the steering system, and the braking system. The function of the chassis is to support and install the automotive engine and its various components and assemblies, form the overall shape of the vehicle, and receive the power of the engine to make the vehicle move and ensure normal driving. Before conducting a full vehicle road test, a fatigue durability road test of the entire automotive chassis needs to be carried out in the laboratory.

[0003] Patent No. CN214373383U proposes a fatigue test device for simulating road tests of automotive chassis. A wheel is fixed on the suspension assembly. The loading system applies lateral load, vertical bump load, actual vehicle weight load, and loading inclination angle to the wheel through a moving plate and drives the wheel to rotate. The drum switching assembly can switch the loading system and the suspension assembly fixed on the loading system between a high-speed road drum assembly and an impact road drum assembly.

[0004] In the above patent, the drum switching assembly includes a horizontal sliding assembly and a mounting table. The horizontal sliding assembly can drive the mounting table to move horizontally. The loading system is fixed on the mounting table. By moving the mounting table, the wheel can be switched between the high-speed road drum assembly and the impact road drum assembly. However, since the mounting table can only drive the wheel to move horizontally, the wheel cannot be adjusted in the vertical direction. In this way, during the wheel switching, interference is likely to occur between the wheel and the high-speed road drum assembly or the impact road drum assembly, affecting the wheel switching and reducing the wheel switching efficiency. Therefore, those skilled in the art have provided a fatigue test device for simulating road tests of automotive chassis to solve the problems raised in the above background art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following is combined with the attached Figures 1-4A further detailed description of the present application is provided below.

[0028] An embodiment of the present application discloses a fatigue test device for simulating road tests of an automotive chassis. Referring to Figures 1-4 , a fatigue test device for simulating road tests of an automotive chassis includes a bracket 1 and a base 2 disposed above the bracket 1. A mounting table 3 is slidably provided at the top end of the base 2. The base 2 is connected to the bracket 1 through a support assembly 4. The bracket 1 is rotatably connected to a rotating shaft 5. Both ends of the rotating shaft 5 are fixed with rotating rods 6. First sliders 7 are fixed to the top ends of the two rotating rods 6. First chutes 8 for the first sliders 7 to slide are provided on both sides of the bottom end of the base 2. A driving assembly 9 for driving the rotating shaft 5 to rotate is provided on the bracket 1.

[0029] In this embodiment, the wheels are fixed to the mounting table 3 through a suspension assembly and a loading system. When switching the wheels, first, under the movement of the driving assembly 9, the rotating shaft 5 is driven to rotate. The rotating shaft 5 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the first slider 7 to slide in the first chute 8, thereby driving the up and down movement of the base 2. The base 2 drives the mounting table 3 to move up and down, thereby driving the wheels to move up and down to adjust the height of the wheels. Then, under the movement of the horizontal sliding assembly driving the mounting table 3, the wheels can be switched, avoiding interference between the wheels, facilitating the rapid switching of the wheels, and improving the switching efficiency of the wheels.

[0030] It should be noted that the present application is an improvement based on the patent number CN214373383U. Structures such as the horizontal sliding assembly, the suspension assembly, the loading system, the high-speed road drum assembly, and the impact road drum assembly have been disclosed in the above patent, so they will not be specifically described in the present application.

[0031] In a further embodiment, as Figures 1-2 shown, the support assembly 4 includes a support plate 41 inserted through the top end of the bracket 1 and fixed to the base 2. A limiting plate 42 located inside the bracket 1 is fixed to the bottom end of the support plate 41. The driving assembly 9 includes a driving motor 91 fixedly provided inside the bracket 1. A driving wheel 92 is fixed to the output shaft of the driving motor 91. A driven wheel 93 meshing with the driving wheel 92 is sleeved on the outer wall of the rotating shaft 5.

[0032] When it is necessary to switch the wheels, first, under the movement of the drive motor 91, the rotation of the driving wheel 92 is driven. The driving wheel 92 drives the driven wheel 93 to rotate, the driven wheel 93 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the first slider 7 to slide in the first chute 8, thereby driving the up and down movement of the base 2. At the same time, with the cooperation of the support plate 41 and the limiting plate 42, the movement of the base 2 is kept stable. The base 2 drives the up and down movement of the mounting table 3, that is, drives the up and down movement of the wheels, adjusts the height of the wheels. Then, when the mounting table 3 is driven by the horizontal sliding assembly to move, the wheels can be switched between the high-speed road drum assembly and the impact road drum assembly, avoiding the interference of the wheels, facilitating the switching of the wheels, and improving the switching efficiency of the wheels.

[0033] In a further preferred embodiment of the present utility model, as Figure 1 shown, a second chute 10 is opened on one side of the base 2. Two second sliders 11 are slidably connected in the second chute 10. Adjusting assemblies 12 for driving the movement of the second sliders 11 are provided on both sides of the base 2. Vertical plates 13 are fixed on one side of the two second sliders 11. Stopping plates 14 located on both sides of the mounting table 3 are fixed at the tops of the two vertical plates 13. A protection assembly 15 is provided on the side of the stopping plate 14 close to the mounting table 3.

[0034] When the horizontal sliding assembly drives the mounting table 3 to move to switch the wheels, first, under the movement of the adjusting assembly 12, the movement of the second slider 11 is driven. The second slider 11 drives the vertical plate 13 to move, and the vertical plate 13 drives the stopping plate 14 to move, adjusting the position of the stopping plate 14. In this way, during the movement of the mounting table 3, when the mounting table 3 hits the stopping plate 14, it stops moving, so that the stopping position of the wheels corresponds to the high-speed road drum assembly or the impact road drum assembly, facilitating the accurate switching of the wheels and improving the switching effect of the wheels.

[0035] In a further embodiment, as Figures 3-4 shown, the adjusting assembly 12 includes an adjusting rod 121 which is threadedly arranged on the side wall of the base 2 and is rotationally connected to the second slider 11. A turning handle 122 is fixed at the end of the adjusting rod 121 located outside the base 2. The protection assembly 15 includes a rubber pad 151 provided on one side of the stopping plate 14. An installation groove 152 adapted to the rubber pad 151 is opened on one side of the stopping plate 14. A first magnet 153 is fixed on the inner wall of the installation groove 152. A second magnet 154 magnetically connected to the first magnet 153 is fixed on one side of the rubber pad 151.

[0036] Before switching the wheels, first manually rotate the two handlebars 122 respectively. The two handlebars 122 drive the two adjusting rods 121 to rotate. During the rotation of the two adjusting rods 121, the movement of the two second sliders 11 is driven. The two second sliders 11 drive the two vertical plates 13 to move. The two vertical plates 13 drive the two stop plates 14 to move, so that the two stop plates 14 respectively move to the positions corresponding to the high-speed road drum assembly and the impact road drum assembly. Then when the mounting table 3 drives the wheels to switch, when the mounting table 3 hits the stop plate 14, it stops moving, which is convenient for the wheels to stop at the designated position, facilitating the accurate switching of the wheels, improving the switching effect of the wheels. And under the connection of the first magnet 153 and the second magnet 154, the rubber pad 151 is fixed on the stop plate 14, which is convenient for protecting the stop plate 14 and the mounting table 3 when they collide through the rubber pad 151, reducing the impact damage between the mounting table 3 and the stop plate 14.

[0037] The implementation principle of a fatigue test device for automotive chassis simulation road test in an embodiment of the present application is as follows: First, the wheels are fixed on the mounting table 3 through the suspension assembly and the loading system. Then, under the movement of the drive motor 91, the rotation of the driving wheel 92 is driven. The driving wheel 92 drives the driven wheel 93 to rotate. The driven wheel 93 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the rotating rod 6 to rotate. The rotating rod 6 drives the first slider 7 to slide in the first chute 8, thereby driving the up and down movement of the base 2. The base 2 drives the up and down movement of the mounting table 3, that is, drives the up and down movement of the wheels to adjust the height of the wheels. Then, during the movement of the mounting table 3 driven by the horizontal sliding assembly, the wheels can be switched between the high-speed road drum assembly and the impact road drum assembly, avoiding interference of the wheels, facilitating the switching of the wheels, and improving the switching efficiency of the wheels. And before the wheels are switched, first manually rotate the two handlebars 122 respectively. The two handlebars 122 drive the two adjusting rods 121 to rotate. During the rotation of the two adjusting rods 121, the movement of the two second sliders 11 is driven. The two second sliders 11 drive the two vertical plates 13 to move. The two vertical plates 13 drive the two stop plates 14 to move, so that the two stop plates 14 respectively move to the positions corresponding to the high-speed road drum assembly and the impact road drum assembly. Then when the mounting table 3 drives the wheels to move and switch, when the mounting table 3 moves and hits the stop plate 14, the mounting table 3 stops moving, which is convenient for the wheels to stop at the designated position, facilitating the accurate switching of the wheels.

[0038] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
