Bidirectional rotation control device and braking system

The invention belongs to the technical field of brake control systems, and discloses a bidirectional rotation control device and a braking system. The bidirectional rotation control device is providedwith a speed reducer for providing speed reduction and a power twister for generating resistance and automatically returning, and the power twister and the speed reducer are installed in a matched mode; the power twister is composed of a power twister outer sleeve, a guide rod upper guide sleeve, a guide rod lower guide sleeve, a torsion spring special-shaped guide rod driving plate component, atorsion spring rotating upper flange plate and the like; the upper flange and the lower flange of the driving plate extend into the inner arc grooves of an upper turntable and a lower turntable respectively, a screw E extends into an outer arc groove of the upper turntable, and a screw F extends into an outer arc groove of the lower turntable. The bidirectional rotation control device can realizesteering control in a bidir
