When bicycle needs to brake in motion process, Fig. 6, Fig. 7, two hold brake-applying handle (31 left side), (31 right side) overcomes traction box (32 left side), when the torsion of (32 right side) interior torsion spring (40) makes the driving gear (C) in the rotating shaft (38) drive ring gear (44) lower pinion (E) on the minor axis (45) to rotate, ring gear (44) drives miniature gears (D) (38) rotation around the shaft of rotating shaft (38) top traction wheel (39) bottom, at this moment, a brake wire (34) that is fixed in traction wheel (39) lateral grooves (F), (36) with the rotation of traction wheel (39) to traction box (32 left side), tighten up in (32 right side), because traction box (32 left side), the mutual collocation of big miniature gears in (32 right side), when brake-applying handle (31 left side), when (31 right side) rotates smaller angle, the traction wheel (39) on rotating shaft (38) top will rotate a bigger angle, make the brake wire (34) that is fixed in traction wheel (39) lateral grooves (F), (36) tighten up long segment distance, Fig. 8, Fig. 9, the other end of the brake wire that tightens up (34) is with the center shaft (47) of rotating disk (48) on shell (46) in the coiler (33) when rotating counterclockwise, because pivoted housing (52) can rotate around screw (51), pulley (50) can rotate around pin (49) separately, Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, when about two strands of brake wires (35) when being subjected to advancing the different pulling force of cover (12) bottom pull bar (A), can constantly rotate automatically regulating flexibly and make about the continuous balance of pulling force of two strands of brake wires (35), under these circumstances, slipper (3) on front-wheel floral disc (1) the both sides Die Scheibenbremses (4) can contact the face that is braked of the interior intermediate plate of front-wheel floral disc (1) (K) both sides simultaneously, be enclosed within pivoted housing (52), brake wire (35) on the pulley (50) rotates counterclockwise with rotating disk (48) simultaneously, and constantly in coiler (33), tighten up, at this moment, joint (15) rotates around pin (17) with the variation that advances cover (12) bottom pull bar (A) angle.At this moment, advance the pull bar (A) of cover (12) bottom to overcome the torsion of torsion spring (8) and propelling cover (12) is rotated around locating bush (7) axis, because between Die Scheibenbremse (4) and the locating bush (7) is the bearing fit of spline and spline, the moving disk (4) of prevention can not be around locating bush (7) rotational, can only be along locating bush (7) axis direction left and right sides crank motion, because Die Scheibenbremse (4) is 40 concavo-convex right-angled trapezium about spending with the base angle that has that advances two abutting ends between the cover (12) to wear two corresponding cooperations, because there are two symmetrical projections (Q) and front fork (2) in locating bush (7) outer end, back vent (21) bottom clamping plate (B), (M) the groove corresponding matching on, after nut (9) assembly at front axle (10) rear axle (24) two ends fastens, locating bush (7) can not be around front axle (10), rear axle (24) rotates, therefore, because the effect of the concavo-convex right-angled trapezium ramp that two abutting ends are worn between Die Scheibenbremse (4) and the propelling cover (12), when advancing cover (12) to overcome the torsion of torsion spring (8) when locating bush (7) rotates, Die Scheibenbremse (4) overcomes the pressure of pull back spring (5), the face that is braked of intermediate plate (K) both sides constantly advances in along locating bush (7) axis direction towards the front-wheel floral disc (1) that rotates around front axle (10), because the diameter of Die Scheibenbremse (4) is big, the frictional area of slipper (3) is big, the lock torque that adds propelling cover (12) is big, therefore, slipper (3) on the both sides Die Scheibenbremse (4) is tightly clamped the interior intermediate plate of front-wheel floral disc (1) (K), because of trailing wheel floral disc (25) is the single face braking, front-wheel floral disc (1) is a double-sided braking, trailing wheel floral disc (25) glancing impact does not need coiler (33), other trailing wheel floral disc (25) is the same with the braking principle of front-wheel floral disc (1), equally, Die Scheibenbremse (4) on the trailing wheel (62) is tightly clamped trailing wheel floral disc (25), simultaneously, Die Scheibenbremse (4) is all in front-wheel floral disc (1), in the annular groove of trailing wheel floral disc (25) intermediate plate (K) both sides, no matter be in fine day or rainy day, can both be very stable, safely and reliably in a short period of time with front-wheel (60), trailing wheel (62) is checked, take-off the brake handle (31 left side), (31 right side), pull back spring (5) on the front axle (10) promotes along about locating bush (7) axis direction, Die Scheibenbremse (4) is got back to before the braking original state time again, because the effect of torsion spring (8) between locating bush (7) and the propelling cover (12), to advance cover (12) to get back to again before the braking original state time, advance pull bar (A) the pulling brake wire (35) of cover (12) bottom make in the coiler (33) rotating disk (48) around center shaft (47) clockwise rotate reset to braking before original state the time, rotating disk (48) cw tightens up a segment distance with brake wire (34) in coiler (33), and because the effect of traction box (32 left side) interior torsion spring (40), the miniature gears (E) of ring gear (44) bottom will drive the driving gear (C) in the rotating shaft (38) and make the brake-applying handle (31 left side) of rotating shaft (38) bottom get back to the preceding original state of braking again, because of trailing wheel (62) is the single face braking, do not need coiler (33), other trailing wheel (62) is the same with the braking principle of front-wheel (60), at this moment, front-wheel floral disc (1) and trailing wheel floral disc (25) brake off, bicycle continues freely to push ahead, what also need special version is: because Die Scheibenbremse (4) is that 40 the height of concavo-convex right-angled trapezium about spending have certain limit with the base angle that has that advances two abutting ends between the cover (12) to wear two corresponding cooperations, because traction box (32 left side), big miniature gears special role of transmission of arranging in pairs or groups mutually in (32 right side), braking, after control two parts are done once to regulate, along with the last slipper (3) of Die Scheibenbremse (4) progressively weares and teares, brake-applying handle (31 left side), the angle that rotate on (31 right side) increases gradually, when slipper (3) does not does not also all wear and tear, inclined-plane on the concavo-convex right-angled trapezium between Die Scheibenbremse (4) and propelling cover (12) the two abutting end faces has not played progradation, end face between the concavo-convex right-angled trapezium is slide relative at grade, at this moment, brake-applying handle (31 left side), the angle maximum that rotate on (31 right side), Die Scheibenbremse (4) can not take place yet to front-wheel floral disc (1), middle (K) direct mechanical wear in the trailing wheel floral disc (25).

Structure design compact and reasonable of the present invention, novel and beautiful appearance, easy to use being quick on the draw, braking potential is strong, and is all very stable, safe and reliable at fine day or rainy day deceleration and stopping performance, except that on ordinary bicycle, three-wheel vehicle, using, be specially adapted to high-speed bicycle, motor bike.
