The invention discloses an anti-rotation device and a braking system.The anti-rotation device comprises an anti-rotation sleeve, a ball screw nut and a cylinder, the anti-rotation sleeve is a hollow barrel, the outer diameter of the ball screw nut is matched with the inner diameter of the anti-rotation sleeve, and the cylinder is arranged in the anti-rotation sleeve; at least two guide rails perpendicular to the cross section of the ball screw nut are arranged on the outer wall of the ball screw nut, anti-rotation ribs perpendicular to the cross section of the anti-rotation sleeve are arranged on the inner wall of the anti-rotation sleeve, the number of the anti-rotation ribs is the same as that of the guide rails, and the guide rails correspond to the anti-rotation ribs in position. And one end of the anti-rotation sleeve is fixedly mounted on the cylinder body. According to the technical scheme, the part cost can be reduced, the assembly technology is optimized, and meanwhile noise of the transmission mechanism can be prevented from being amplified.
