Description

[0002] With the rapid development of modern transportation, the number of vehicles on the road has increased dramatically, and the chassis, as one of the key structures of a car, has also developed accordingly. Typically, a suspension system and a steering system are installed on the chassis. The suspension system is a connecting structure system located between the vehicle body, frame, and wheels. When a car is driving on the road, it experiences vibrations and impacts due to changes in the road surface. The suspension system absorbs these impact forces, allowing the car to drive smoothly and safely. The steering system is a mechanism located on the chassis used to control the car's steering. Through the driver's operation, the wheels on the steering axle can be deflected at a certain angle relative to the car's longitudinal axis, changing or restoring the car's direction of travel. The performance of both the suspension and steering systems directly affects the safety of the vehicle.
[0003] During vehicle manufacturing, to ensure product performance meets national standards and design requirements, various inspection positions and processes are specifically set up at each stage of the manufacturing process to guarantee the overall quality of the vehicle. In related technologies, chassis system inspection requires personnel to crawl under the vehicle for testing. Dynamic testing of the movement of some moving components in the steering system requires two people working together, one inside and one underneath the vehicle, which presents challenges due to wasted manpower and the safety risks of overlapping operations.
