Steering mechanism, chassis device and navigation transport vehicle

The invention discloses a steering mechanism, a chassis device and a navigation transport vehicle. The steering mechanism comprises a first rotary disc, a second rotary disc and a first driving part, and the first rotary disc and the second rotary disc are arranged at an interval and can rotate; one end of the first driving part is rotationally connected with the first rotary disc, the other end of the first driving part is rotationally connected with the second rotary disc, and the first driving part can output linear motion to drive the first rotary disc and the second rotary disc to rotate synchronously. Due to the fact that the two ends of the first driving part are rotationally connected with the first rotating disc and the second rotating disc respectively, when the first driving part outputs linear motion through stretching and retracting, the first rotating disc and the second rotating disc can be pulled and driven to rotate synchronously, the first wheel is installed on the first rotating disc, and t
