The axes move toward each other.

The traction arm 7 is mounted on the inner side of the left side static plate 2A and the right side static plate 2B. The traction arm 7 is located inside the left side caliper 1A and the right side caliper 1B. The traction arm 7 has the function of pulling the brake wire 13 while having The brake pad is returned to the spring, and the left side movable plate 3A and the right side moving plate 3B are respectively fixed to both sides of the traction arm 7 by a left traction arm locking screw 4A and a right traction arm locking screw 4B, respectively. A left side unlocking ring 8A and a right side unlocking ring 8B are respectively disposed in the circular grooves on the back side of the traction arm locking screw 4A and the right side traction arm locking screw 4B. The left unlocking ring 8A and the right unlocking ring 8B function as When the brake is prevented from being braked, the brake disc is locked to play the unlocking function. The left side unlocking ring 8A and the middle through hole of the right unlocking ring 8B are respectively provided with a left magnet 6A and a right magnet 6B, and the left magnet 6A and the right side are respectively disposed. The left side brake pad 9A and the right side brake pad 9B are respectively adsorbed under the magnet 6B, and the left side magnet 6A and the right side magnet 6B are used for simultaneously adsorbing the left side unlocking ring 8A, the right side unlocking ring 8B, the left side brake piece 9A, and The rear brake pad 9B is provided with a brake wire guiding sleeve 11 on the rear side of the traction arm 7. The brake wire guiding sleeve 11 is provided with a brake wire adjusting knob 18 on the rear side thereof, and a brake wire is also mounted on the upper portion of the pulling arm 7 a lock nut 12 and a brake wire locking screw 14 which passes through the brake wire guide sleeve 11, the brake wire lock nut 12 and the traction arm 7 in sequence from the wire slot 1C of the right side caliper 1B The left side caliper 1A and the right side caliper 1B are respectively fixed with a left plastic cover 15 and a right plastic cover 17 between the left side caliper 1A and the right side caliper 1B. The left plastic cover 15 and the right plastic cover 17 are respectively disposed. A cover 16 is provided.

The left side moving plate 3A and the right side moving plate 3B are provided with a hexagonal step 3C. The pulling arm 7 is provided with a hexagonal hole 7A, which cooperates with the hexagonal step 3C, and the left side moving plate 3A and the right side moving plate 3B. The hexagonal step 3C is inserted into the hexagonal hole 7A of the towing arm 7, and the left side moving plate 3A and the right side moving plate locking screw 4B are respectively passed through the left side moving arm locking screw 4A and the right side moving plate 3B, respectively. The traction arm 7 is connected; the left plastic cover 15 and the right plastic cover 17 are respectively provided with a slide rail 15A, 17A, and the top cover 16 passes through the slide rail 15A of the left plastic cover 15 and the slide rail 17A of the right plastic cover 17. The sliding arm covers the traction arm 7; the traction arm 7 is made of spring steel.

The brake wire 13 passes through the brake wire guide sleeve 11 through the brake wire lock nut 12 and the traction arm 7, and then passes through the wire slot 1C of the right side caliper 1B, so that the entire brake wire 13 is also hidden. The left side plastic cover 15, the right plastic cover 17 and the top cover 16 do not have the traction arm 7 and the brake wire 13 in the entire appearance. When the brake wire 13 pulls the traction arm 7, the left side movable plate 3A and the left side moving plate 3A and the right side steel plate 5B are driven by the left side moving plate 3A and the right side moving plate 3B, and the left side moving plate 3A and The right side moving plate 3B moves toward the axis along the axis of rotation, thereby pushing the left unlocking ring 8A and the right unlocking ring 8B to move toward each other, and then transmitting the motion to the left side through the transmission of the left unlocking ring 8A and the right unlocking ring 8B. The brake pad 9A and the right brake pad 9B, thereby achieving a braking action, so that the left side brake pad 9A and the right side brake pad 9B do not hold the disc under the action of the left unlocking ring 8A and the right unlocking ring 8B during braking. The disc is also not left by the left brake pad 9A and the right brake pad 9B.

At this time, the traction arm 7 is under the force of the traction force of the brake wire 13 and the thrust of the left side movable plate 3A and the right side moving plate 3B, and the traction arm 7 is in a squeezed state, when not braking, then The pulling force exerted on the traction arm 7 by the brake wire 13 disappears, and the traction arm 7 starts to rebound after the tension of the traction arm 7 itself, at which time the left side moving plate 3A, the right side moving plate 3B and the towing arm 7 returning to the original position along the steel ball raceway rebound, thereby realizing the brake release function; the entire brake and release action are all wrapped in the left side caliper 1A, the right side caliper 1B, the left side plastic cover 15 and the right side plastic cover 17 Completed under.

The brake pad in the invention is double-acting at the time of braking, so that the disc is not deformed in the center, and the service life of the disc is prolonged. When the loading adjustment is performed, the brake can be adjusted by simply clamping the brake lever, and the adjustment is simple and easy; The arm is hidden in the top cover, so the shape is simple and beautiful. It is a product that undertakes high-end mechanical disc brakes and low-end hydraulic disc brakes. The market prospect has potential.
