Steering Gear
★Exhibit Content: Automotive Steering Gear ★Interaction: Mechanical interactive demonstration ★Operation: Turn the steering wheel left and right to observe changes in the wheel steering state. ★Exhibit Description: The exhibit consists of an operating device and an automotive steering gear demonstration mechanism. Visitors turn the steering wheel left and right to observe the process of wheel steering changes. ★Scientific Principle: How does the steering wheel drive the wheels to steer? There are many types of automotive steering mechanisms. This structure demonstrates a worm-and-crank-pin steering mechanism, in which the worm is the driving component and the crank pin is the driven component. The worm has trapezoidal threads, and the finger-shaped conical pin is supported on the crank by bearings. The crank and the steering rocker shaft are made as one piece. During steering, the steering wheel rotates the worm, and the conical pin embedded in the worm's helical groove both rotates on its own axis and moves in an arc around the steering rocker shaft, thereby driving the crank and steering drop arm to swing, and then through the steering linkage causing the steering wheels to deflect. This type of steering gear is commonly used on trucks with greater steering force.
