The bracket 2 connects the base 1 and the steering wheel 3, and the steering wheel assembly 4 is connected to a steering device 22 on the base 1. A wire-controlled device 21 connected to the steering wheel 3 is disposed within the bracket 2. The wire-controlled device 21 is connected to the steering device 22, and the direction of rotation of the steering wheel 3 is controlled by the wire-controlled device 21, which transmits a signal to the steering device 22. The steering device 22 then drives the steering wheel assembly 4 to perform a steering action. In this invention, the bracket and base are connected, the steering wheel is mounted on the bracket, and the lower end of the steering wheel is connected to the wire-controlled device within the bracket. Simultaneously, the wire-controlled device is connected to the steering device on the base, and the steering device is connected to the steering wheel assembly. When the steering wheel rotates, the wire-controlled device transmits a signal to the steering device, which controls the steering wheel assembly to swing left and right, resulting in smooth steering. Compared to existing technologies, this invention is more appealing to consumers, and the bracket has a hexagonal structure with no pivot connection between the bracket and the base, relying entirely on the wire-controlled device and steering device for a novel structure.

[0026] In the aforementioned steering structure for a four-wheeled vehicle, the steering device 22 includes a motor 221, a reducer, a motor mounting base 222, a steering shaft 223, and two steering linkages 224.
