AI Technical Summary
In the existing technology, the test piece needs to be replaced during the testing of the steering wheel drive device, which makes the testing inconvenient and poses safety hazards, especially when bearing heavy loads.
A test system for a steering wheel structure was designed, including a frame body, a follower bearing tray, and a control system. The system integrates the testing of driving, steering, and load-bearing functions through software programs. The follower bearing tray structure eliminates the need to switch to a dedicated steering test piece. The system is combined with torque and speed sensors and loads for testing.
It simplifies the testing process, eliminates safety hazards, reduces labor costs, enables autonomous testing and status monitoring of the steering wheel drive device, and improves testing efficiency and reliability.
