When the brake is performed, a foot pedal is stepped on, brake fluid in the brake caliper sequentially passes through the first interface 112, the channel 1111a and the second interface 113 to reach the brake caliper, the brake caliper clamps a brake pad, so that the speed of a wheel is reduced, when the wheel is locked, the servo motor 115 drives the valve core 1111 to rotate for 30 degrees, as shown in fig. 4, at the moment, the second interface 113 and the third interface 114 are communicated through the channel 1111a, the brake fluid in the brake caliper leaves the brake caliper through the second interface 113, the channel 1111a and the third interface 114, the pressure in the brake caliper is reduced, the brake caliper braking force of the brake caliper is reduced, the wheel is unlocked, when the rotating speed of the wheel is accelerated again, the servo motor 115 drives the valve core to rotate for 30 degrees in the reverse direction, the first interface 112 and the second interface 113 are communicated through the channel 1111a, the brake fluid in the brake caliper is input into the brake caliper again, and the braking force of the brake caliper is increased again. By this reciprocation, in the braking process, the servo motor 115 drives the valve element 1111 to rotate in a reciprocating manner. And since the rotation groove 111 and the valve body 1111 are in contact, the valve body 11 generates heat, and the heat dissipation groove 116 contributes to increase heat dissipation performance. Meanwhile, the valve core has small rotation amplitude, small vibration and quick response.

When the valve body 11 is disassembled, the fixing bolt 122 is rotated, the fixing bolt 122 is removed, then the stopper pin 125 is pressed down, so that the stopper pin 125 enters the chute 124, then the valve body 11 is rotated, the valve body 11 rotates around the axis of the positioning shaft 119, the connecting column 121 moves from one end of the long hole 1171 to the other end, then the valve body 11 and the fixing base 12 are separated, and the stopper 1211 passes through the through hole 1171a.

When the valve body 11 is installed, the valve body 11 is placed on the fixed seat 12, the first fixing plate 117 presses the limit pin 125, the spring is compressed, the limit pin 125 enters the sliding groove 124, the positioning shaft 119 enters the positioning hole 123, the limit head 1211 passes through the through hole 1171a, then the valve body 11 is rotated, the connecting column 121 moves to the other end of the long hole 1171 along the long hole 1171, at the moment, under the action of the spring, the end part of the limit pin 125 protrudes out of the fixed seat 12 and is abutted against the first fixing plate 117, and then the fixing bolt 122 passes through the bolt hole and is in threaded connection with the fixed seat 12.
