A steer-by-wire steering mechanism with a safety redundancy function and capable of implementing independent control on steering motions of left and right wheels is provided, including a coupler (1), a steering executing mechanism, and a steering driving mechanism. The steering executing mechanism includes a first steering device (2) and a second steering device (3), and the steering driving mechanism includes a first motor (4) and a second motor (5). With the control on coupling states of wheels and a steering wheel (6-1) by the coupler (1), redundancy control of a steering system can be realized in failure states such as a single-side steering motor failure, a two-side steering motor failure, and a tire burst. The steering mechanism helps ensure driving safety, and can be used in steering systems of vehicles such as an intelligent vehicle, a self-driving vehicle, and a new energy vehicle.
