Description

Technical Field

[0001] This utility model relates to the field of automotive component testing technology, specifically a torsion testing device for steering wheel testing. Background Technology

[0002] With the continuous improvement of productivity, automobiles have become an indispensable means of transportation. In terms of automobile manufacturing and safety performance evaluation, the performance of the steering wheel is crucial. Among them, torsional performance is a key indicator for measuring the quality and reliability of the steering wheel. As the core component for the driver to control the direction of the vehicle, the steering wheel must have good torsional characteristics. On the one hand, during normal driving, the driver expects the steering wheel to have moderate torsional force, comfortable and precise control, so that the vehicle's direction can be changed easily and accurately. On the other hand, in extreme situations, such as collisions or emergency avoidance, the steering wheel must be able to withstand a certain degree of torsional force without breaking or severely deforming, in order to ensure the safety of the driver and the integrity of the vehicle's control system. Therefore, it is necessary to test it.

[0003] Chinese Utility Model Patent Publication No. CN216791603U discloses a positioning fixture for steering wheel fatigue testing. This positioning fixture has a simple structure and can firmly fix the steering wheel on the base, preventing loosening during steering wheel positioning and thus preventing the impact on the detection accuracy of the steering wheel during torsional fatigue testing. However, this positioning fixture can limit the steering wheel, making it inconvenient to conduct tests under different conditions, resulting in significant limitations during testing. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a torsion testing device for steering wheel testing, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a torsion testing device for steering wheel testing, including a workbench and a testing component. A mounting plate and a profile frame are fixedly installed on the top of the workbench. A top plate is fixedly installed on the other end of the profile frame away from the mounting plate. A mounting bracket is fixedly installed on the top of the mounting plate. A fixing plate is fixedly installed on the end of the mounting bracket away from the mounting plate. A connecting sleeve is fixedly installed at the center point of the fixing plate. A connecting column and a steering wheel body are inserted into the inner surface of the connecting sleeve.

[0006] The test component includes a second mounting plate fixedly installed at one end of the top plate close to the mounting plate 1. A telescopic cylinder is fixedly installed at the end of the second mounting plate away from the top plate. A second connecting sleeve is fixedly installed on the output shaft of the telescopic cylinder. A second connecting column is fixedly installed on the inner surface of the second connecting sleeve. A rotating sleeve is rotatably installed on the second connecting column. A connecting rod with a cross-section in an "L" shape or an "|" shape is fixedly installed at the other end of the rotating sleeve away from the second connecting sleeve. A second limiting sleeve and a second limiting plate adapted to the steering wheel body are provided at the other end of the connecting rod away from the rotating sleeve.

[0007] Preferably, a fixing frame is fixedly installed at the end of the connecting rod away from the second connecting sleeve. A first limiting column is provided at one end of the fixing frame. A first limiting sleeve and a first limiting plate are rotatably installed at the other end of the first limiting column away from the fixing frame.

[0008] Through the above technical solution, by the mutual cooperation of the first limiting column, the first limiting sleeve and the first limiting plate, the angle of the upper part can be conveniently adjusted. And when the angle adjustment is completed, it can be fixed by bolts, which is convenient for realizing tests at different angles.

[0009] Preferably, a second limiting column is provided on the inner surface of the first limiting sleeve. A second limiting sleeve is rotatably installed on the inner surface of the second limiting column. A second limiting groove is provided on the inner surface of the second limiting sleeve, and the second limiting groove is adapted to the steering wheel body.

[0010] Through the above technical solution, by the adaptation of the second limiting groove to the steering wheel body, it can closely fit the steering wheel body, provide stable support and restraint for the steering wheel during the test, and at the same time, the design of the rotational connection between the second limiting column and the second limiting sleeve enables the steering wheel body to rotate smoothly when subjected to a torsional force, ensuring the smooth progress of the torsional test and accurately simulating the torsional situation of the steering wheel in actual use.

[0011] Preferably, a transparent plate is fixedly installed at one end of the workbench close to the profile rack. A flip plate is rotatably installed at the end of the profile rack away from the transparent plate through a hinge. A handle is fixedly installed at the end of the flip plate away from the workbench.

[0012] Through the above technical solution, the transparent plate can play a certain protective role, preventing accidental splashes from hurting the operator during the test, and at the same time facilitating the observation of the test situation. The flip plate is rotatably installed through a hinge, and the operator can conveniently open or close the flip plate through the handle, which is convenient for maintaining, adjusting the equipment inside, and placing or taking out test samples.

[0013] Preferably, the mounting bracket has an "L" shaped cross-section, and a positioning groove 1 is provided at one end of the mounting bracket near the workbench. A limiting bracket is provided at the other end of the mounting bracket near the workbench. The limiting bracket has a positioning groove 2 that matches the positioning groove 1 from top to bottom.

[0014] Through the above technical solution, by using the cooperation of positioning groove one, positioning groove two and positioning bolt, the position of the limiting frame on the mounting frame can be flexibly adjusted. Thus, according to the steering wheel body of different sizes or structures, its installation position and angle can be accurately positioned and fixed, which enhances the equipment's versatility for testing different types of steering wheels. At the same time, when testing steering wheels in different directions and at different angles, the installation position can be easily adjusted.

[0015] Preferably, there are two identical limiting frames, positioning grooves, and positioning bolts, and the two limiting frames, positioning grooves, and positioning bolts are symmetrically distributed about the center line of the mounting frame.

[0016] Through the above technical solution, the two sets of symmetrically distributed limiting brackets, positioning grooves and positioning bolts can fix and limit the steering wheel body symmetrically from both sides, so that the steering wheel is subjected to more uniform force during the test, avoiding deviations in test results due to uneven force on one side, and effectively improving the accuracy of the test.

[0017] Preferably, the outer surface of the fixing plate is provided with a plurality of equidistant limiting grooves, which are adapted to the mounting plate.

[0018] Through the above technical solution, the equidistantly distributed limiting grooves allow for multiple options in the installation position of the fixing plate on the mounting plate. The height and angle of the fixing plate can be flexibly adjusted according to actual testing needs, further optimizing the equipment's adaptability to different steering wheel torsion tests and meeting diverse testing scenarios.

A first limiting post 1808 is provided at one end of the fixing bracket 1807. A first limiting sleeve 1809 and a first limiting plate 1810 are rotatably installed at the other end of the first limiting post 1808 away from the fixing bracket 1807. The advantage is that the angle of the upper part can be easily adjusted by the cooperation of the first limiting post 1808, the first limiting sleeve 1809 and the first limiting plate 1810.

[0037] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0038] Specifically, the mounting bracket 8 has an "L"-shaped cross-section. A positioning groove 9 is provided at one end of the mounting bracket 8 near the worktable 1, and a limiting bracket 10 is provided at the other end of the mounting bracket 8 near the worktable 1. The limiting bracket 10 has a positioning groove 11 from top to bottom that matches the positioning groove 9. Positioning bolts 12 are threaded onto the inner surfaces of the positioning grooves 9 and 11. The advantage is that by utilizing the cooperation of the positioning grooves 9, 11, and 12, the position of the limiting bracket 10 on the mounting bracket 8 can be flexibly adjusted. This allows for precise positioning and fixing of the steering wheel body 17 according to different sizes or structures, enhancing the equipment's versatility for testing different types of steering wheels. Furthermore, when testing steering wheels in different orientations and at different angles, the installation position can be easily adjusted.

[0039] Specifically, there are two identical limit brackets 10, positioning grooves 11, and positioning bolts 12. The two limit brackets 10, positioning grooves 11, and positioning bolts 12 are symmetrically distributed about the center line of the mounting bracket 8. The advantage is that the two sets of symmetrically distributed limit brackets 10, positioning grooves 11, and positioning bolts 12 can fix and limit the steering wheel body 17 symmetrically from both sides, so that the steering wheel is subjected to more uniform force during the test, avoiding deviations in test results due to uneven force on one side, and effectively improving the accuracy of the test.

[0040] Specifically, the outer surface of the fixing plate 13 is provided with multiple equidistant limiting grooves 14, which are adapted to the mounting plate 2. The advantage is that the equidistant limiting grooves 14 allow for multiple options in the installation position of the fixing plate 13 on the mounting plate 2. The height and angle of the fixing plate 13 can be flexibly adjusted according to actual testing needs, further optimizing the adaptability of the equipment to different steering wheel torsion tests and meeting diverse testing scenarios.

[0041] Working principle: During use, two groups of symmetrically distributed limiting frames 10, positioning grooves two 11, and positioning bolts 12 can symmetrically fix and limit the steering wheel body 17 from both sides, ensuring uniform force during testing and improving test accuracy. The fixing plate 13 fixed at one end of the mounting frame 8 away from the first mounting plate 2 has equally spaced limiting grooves one 14 on its outer surface, which are adapted to the first mounting plate 2, enabling flexible adjustment of the height and angle of the fixing plate 13 and optimizing the adaptability of the device to different steering wheel torsion tests. The connecting sleeve one 15 fixed at the center point of the fixing plate 13 is used to insert and connect the connecting column one 16 and the steering wheel body 17, realizing the preliminary installation of the steering wheel body 17 on the device. The second mounting plate 1801 of the test component 18 is fixed at one end of the top plate 4 close to the first mounting plate 2, and the telescopic cylinder 1802 fixed at the end away from the top plate 4 is the key component providing power. The connecting column two 1804 is fixedly connected inside the connecting sleeve two 1803 on the output shaft of the telescopic cylinder 1802. The connecting column two 1804 is rotatably installed in the rotating sleeve 1805, and the connecting rod 1806 fixed at the other end of the rotating sleeve 1805 can be flexibly selected to have a cross-section in an "L" shape or an "I" shape according to different test situations to meet diverse test requirements. The second limiting sleeve 1812 and the second limiting plate 1814 adapted to the steering wheel body 17 are provided at one end of the connecting rod 1806 away from the rotating sleeve 1805, and are used to further limit and restrain the steering wheel body 17 during testing. The first limiting column 1808 provided on the fixing frame 1807 fixed at one end of the connecting rod 1806 away from the connecting sleeve two 1803, and the first limiting sleeve 1809 and the first limiting plate 1810 rotatably installed at the other end thereof cooperate with each other to adjust the angle of the parts above the test component 18. After the angle adjustment is completed, it can be fixed by bolts, facilitating the realization of tests at different angles. The second limiting column 1811 inside the first limiting sleeve 1809, and the limiting groove two 1813 opened on the inner surface of the second limiting sleeve 1812 rotatably installed thereon is adapted to the steering wheel body 17, providing stable support and restraint for the steering wheel body 17 during testing. At the same time, the rotational connection design of the second limiting column 1811 and the second limiting sleeve 1812 ensures that the steering wheel body 17 can rotate smoothly when subjected to a torsional force, accurately simulating the torsional situation of the steering wheel in actual use.
