Vehicle, initiative braking system and brake equipment thereof

The utility model relates to an initiative braking system's brake equipment, initiative braking system and vehicle. Brake equipment includes: have the output shaft the motor, be fixed in coaxially the output shaft around the wheel and, one end is fixed in connect in brake connecting rod or brake pedal's wire rope around wheel, the other end, brake equipment sets up and does: when when the wheel rotates along the first direction, the wire rope winding is in around taking turns to, and drive corresponding displacement takes place for brake pedal, and corresponding displacement volume with wire rope's winding volume is directly proportional, wherein, have operating position around taking turns, work as when the wheel lies in this operating position, brake pedal's displacement volume is the maximum value, wherein, brake equipment still includes a limit structure, and a limit structure is used for the restriction follow around the wheel operating position follows the first direction continues to rotate.
