Please refer to FIG. 7 to FIG. 9 for continued. According to the above-mentioned member, in the first embodiment of the present invention (the rigidity of the compression spring is greater than the first brake pulling force): when the user activates the rear brake lever 32 or the handcuff handle 31, the rear view is utilized When the brake lever brake line 321 or the handlebar brake line 311 (or the front brake lever 35, as shown in FIG. 2) applies a first brake force P1 to the pulley weight assembly 22, the pulley weight assembly 22 pulls the pulley weight assembly block 22 Or the rear wheel brake cable (341, 341') (moving toward the input end 211) and generating a displacement that eliminates a free clearance G stroke of one of the corresponding rear wheel brakes (34, 34'), and simultaneously When the movable pulley 222 is deflected by an angle to a force balance state, the columnar end 3311a of the front wheel brake wire 331 is located at the third slot 2233 at a distance from the slot end 22332. The position of T, at this time, the rear wheel brake wire (341, 341') is uncompressed because the rigidity of the compression spring 242 of the rear wheel brake line reserve unit (24, 24') is greater than the first brake force P1 ( Of course, if the rigidity of the compression spring 242 is less than the first brake pulling force P1, the rear wheel brake wire (341, 341') compresses a part of the free travel of the compression spring and/or the rear wheel brake (34, 34'). Part of the free clearance G stroke).

Then, when the rear brake lever brake line (341.341') or the handle handle brake line 311 is applied with a second brake pull force P2 greater than the first brake pull force P1 to the pulley balance block assembly 22, the pulley balance The block assembly 22 continues to move toward the input end 211 of the housing 21, at which time the or rear wheel brake wire (341, 341') begins to compress the compression spring 242, while the front wheel brake wire 331 is cylindrical. When the end 3311a moves to the position of the slot end 22332 of the third slot 2233, and then continues to move a stroke greater than a free gap G of one of the brake arms 332, the front wheel brake 33 can be made. When the braking force of the brake is generated, and the compression amount of the compression spring 242 reaches the limit or the distance 244 is zero, the rear wheel brake (34, 34') can generate the braking force (in this embodiment, when the rear wheel When the brake (34, 34') begins to generate the braking force, if the front wheel brake 33 is to generate the interlocking braking force, the force to be pulled by the front wheel braking wire 311 must overcome the guiding stroke T of the front wheel braking wire 331. And a free gap G of the front wheel brake 33, that is, The rear wheel brake line reserve unit (24, 24') must pull out the aforementioned strokes, and the rear wheel brake line reserve unit (24, 24') can make the rear wheel brake line (341, 341'). ) compensate the trip appropriately).

In a second embodiment of the present invention (the stiffness of the compression spring is less than the first brake pull): When the first brake lever brake line or the handlebar brake line applies a first brake force to the pulley balance block assembly, the pulley balance block assembly pulls the or the rear wheel brake pull line, and generates a corresponding elimination When the displacement of one of the rear wheel brakes is free of the clearance stroke, and at the same time, the angular end of the front wheel brake wire is located at the slot end of the third slot when the axis of the movable pulley is deflected by an angle to the force balance state. Position of the portion, at this time, the rear wheel brake line (341, 341') is uncompressed because the rigidity of the compression spring 242 of the rear wheel brake line reserve unit (24, 24') is greater than the first brake force P1 (of course If the stiffness of the compression spring 242 is less than the first brake force P1, the rear wheel brake line (341, 341') compresses a portion of the free travel of the compression spring and/or a portion of the rear wheel brake (34, 34') Free clearance G stroke).

Then, when the second brake lever brake line or the handlebar brake line applies a second brake force greater than the first brake force to the pulley weight assembly, the pulley weight assembly continues to the input of the housing. The end moves, at which time the or the rear wheel brake wire further compresses the compression spring, and at the same time, the cylindrical end of the front wheel brake wire at the position of the slot end of the third slot is subjected to When the third slot is pulled, a stroke greater than a free gap of the brake rocker arm of the front wheel brake can generate the brake braking force of the front wheel brake, and the compression amount of the compression spring reaches the limit or the distance is zero. Then, the rear wheel brake can generate the braking force of the brake (in this embodiment, when the rear wheel brake (34, 34') starts to generate the braking force, if the front wheel brake 33 is to generate the interlocking braking force, the front wheel The force to be pulled by the brake wire 311 must overcome the free clearance G of the front wheel brake 33, that is, the rear wheel brake line reserve unit (24, 24') must pull out the aforementioned strokes, and the rear wheel brake Line reserved unit (24, 24 ) Enabling the wheel to brake wire (341, 341 ') to properly compensate stroke).

As shown in FIG. 7, further, the inside of the casing 21 corresponds to a center to be described later.
