Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to an intelligent multi-channel test bench for automotive steering knuckles. Background Technology

[0002] The steering knuckle is a crucial component of a car chassis, connected to the suspension, front axle, steering system, and brake assembly. It bears the load of the front of the vehicle, supports and drives the front wheels to rotate around the kingpin, and enables the vehicle to steer flexibly and drive normally. The reliability of the steering knuckle directly affects the normal operation of the vehicle and the safety of its occupants. In particular, the steering knuckle is subjected to varying impact loads during vehicle operation, thus requiring higher standards for its strength, stiffness, and overall mechanical properties. Therefore, one of the most important tasks in the development of steering knuckles is verifying whether their fatigue life meets the requirements of various operating conditions, necessitating the use of an intelligent multi-channel testing bench for automotive steering knuckles.

[0028] like Figure 1 As shown, an intelligent multi-channel test bench for automotive steering knuckles includes a workbench 1. A test component 2 is fixedly connected to the upper surface of the workbench 1. Support adjustment components 3 are fixedly connected to the four corners of the lower surface of the workbench 1. Support protection components 4 are fixedly connected to the opposite surfaces of the four support adjustment components 3 and are located below the workbench 1. An auxiliary moving component 5 is fixedly connected to the upper surface of the support protection component 4 and is located between the support protection component 4 and the workbench 1.

[0029] First, with the help of the auxiliary moving component 5, the device can be moved to a suitable location. Then, with the help of the auxiliary moving component 5, the lower surfaces of the four support adjustment components 3 can be made to overlap with the ground, so that the device can be firmly fixed on the ground. Next, with the help of the four support adjustment components 3, the workbench 1 and the test component 2 can be raised to a suitable height. Finally, with the help of the test component 2, the automotive steering knuckle can be tested.

[0030] like Figure 2 As shown, the support and protection assembly 4 includes a support plate 41. The inner cavities of the four corners of the support plate 41 are fixedly connected to the outer walls of the lower parts of the four hydraulic rods 32 respectively. Four shock absorbers 42 are fixedly connected to the upper surface of the support plate 41. The upper surfaces of the four shock absorbers 42 overlap with the lower surface of the workbench 1 respectively.

[0031] The shock absorber 42 provides shock absorption and protection for the workbench 1 during descent, thus preventing collisions.

[0032] like Figure 3 As shown, hydraulic rods 32 are fixedly connected to the inner cavities of the lower parts of the four support columns 31, and elastic rubber pads 33 are fixedly connected to the output ends of the four hydraulic rods 32; wear-resistant pads are fixedly connected to the upper surfaces of the four elastic rubber pads 33, and the upper surfaces of the four wear-resistant pads overlap with the lower surface of the worktable 1 respectively.

[0033] The hydraulic rod 32 allows the worktable 1 to move upwards, enabling the height of the worktable 1 and the test component 2 to be adjusted according to usage requirements. The elastic rubber pad 33 and the wear-resistant pad provide a certain degree of buffering and protection between the hydraulic rod 32 and the worktable 1.

[0034] like Figure 4 , Figure 5 As shown, the support adjustment assembly 3 includes four wear-resistant sliding sleeves 34. The upper surfaces of the four wear-resistant sliding sleeves 34 are fixedly connected to the lower surface of the worktable 1. Support columns 31 are slidably connected to the outer walls of the four wear-resistant sliding sleeves 34. Elastic rubber sleeves 35 are fixedly connected to the inner cavities of the four wear-resistant sliding sleeves 34. Shock-absorbing steel plates 36 are fixedly connected to the inner cavities of the four elastic rubber sleeves 35. The upper surfaces of the elastic rubber sleeves 35 and the shock-absorbing steel plates 36 are fixedly connected to the lower surface of the worktable 1.

[0035] Through the action of the shock-absorbing steel plate 36 and the support column 31, the workbench 1 can move stably up and down above the support and protection component 4. The wear-resistant sliding sleeve 34 and the elastic rubber sleeve 35 provide a certain degree of protection between the support column 31 and the shock-absorbing steel plate 36, thus playing a protective role during the experiment.

[0036] like Figure 6 As shown, the auxiliary moving component 5 includes a second hydraulic rod 51. The lower surface of the second hydraulic rod 51 is fixedly connected to the upper surface of the center part of the support plate 41. The output end of the second hydraulic rod 51 is fixedly connected to a support frame 52, and the support frame 52 is located on the lower surface of four elastic rubber pads 33. The inner cavities of the four corners of the support frame 52 are fixedly connected to the output ends of the four first hydraulic rods 32 respectively.

[0039] The four moving wheels 54 are lowered by the action of hydraulic rod 2 51 and hydraulic rod 1 32, which supports the four support columns 31. The device can then be moved by the four moving wheels 54. After moving to a suitable location, the four moving wheels 54 can be moved upward by the action of hydraulic rod 2 51 and hydraulic rod 1 32. At this time, the lower surface of the four support columns 31 re-engages with the ground, thereby fixing the device and making it easy to move and fix during use.

[0040] The working principle of this utility model is as follows: First, the four moving wheels 54 are lowered by the action of hydraulic rod 2 51 and hydraulic rod 1 32, supporting the four support columns 31. At this time, the four moving wheels 54 can be moved. After moving to a suitable location, the four moving wheels 54 can be moved upward by the action of hydraulic rod 2 51 and hydraulic rod 1 32. At this time, the lower surface of the four support columns 31 re-overlaps with the ground, thereby fixing the device. Then, the worktable 1 can be moved upward by the action of hydraulic rod 1 32, so that the height of the worktable 1 and the test component 2 can be adjusted according to the usage requirements. Finally, the test component 2 can be used to test the automobile steering knuckle.
