Description

Technical Field

[0001] The invention relates to the technical field of durability testing, in particular to a steering wheel performance testing device. Background Art

[0002] The steering wheel steering system is a vital part of the car. A sensitive and high-strength steering system can help the car driver to change the direction of the car in time during driving, greatly improving the safety performance of the car. As the interactive component between the car steering system and the driver, the design strength of the steering wheel is particularly important. After the steering wheel is manufactured, it is necessary to conduct a static pressure test and a fatigue test on the steering wheel to ensure that the safety performance of the steering wheel meets the standards of the automobile factory. However, there are no relevant standards and requirements for the static pressure test and fatigue test equipment of the existing steering wheel skeleton, so usually a device is designed for each test. Different equipment needs to be replaced when testing the steering wheel, resulting in the need to clamp the steering wheel multiple times during the test, which reduces the test efficiency. At the same time, the test angle of the existing test equipment is fixed and cannot simulate the force of the steering wheel during actual use. Summary of the invention
