Technical Field
[0001] The utility model relates to the technical field of vehicle manufacturing, in particular to a novel steering mechanism. Background Art
[0002] Modern vehicles all have steering mechanisms to meet the steering needs of users. The so-called automobile steering mechanism is a special mechanism used to change or restore the direction of the car when it is driving. However, the steering angle of the existing steering mechanism is not very large, and as the turning angle increases, it will get stuck when it reaches a certain angle. In addition, the turning radius of the existing steering mechanism when the vehicle is turning is also large, and it is difficult for the vehicle to turn around in a relatively narrow terrain.
[0003] Therefore, the technical problems reflected above are problems that need to be solved urgently by those skilled in the art. Utility Model Content
