The present application provides a steering mechanism, a vehicle, and an apparatus and method for producing a steering mechanism, and belongs to the technical field of vehicles. Wherein the steering mechanism comprises a first directive wheel, a second directive wheel, a first driving device, and a second driving device. The first driving device is connected to the first directive wheel; and the second driving device is connected to the second directive wheel. The first driving device and the second driving device are configured to separately drive the first directive wheel and the second directive wheel respectively, thus making the first directive wheel and the second directive wheel deflect in the same direction to achieve steering. No linkage relationship exists between the two directive wheels, whereby the two directive wheels do not need to be connected through a complex mechanical transmission mechanism, and a structure of the steering mechanism is simplified.
