Therefore, the first brake lever 11 cannot continue to increase the force on the connecting member 8b, so the braking force of the second brake generator 4 will not increase excessively, so as to avoid the excessive force of the second brake generator 4 during the joint braking. the danger caused. Or, if the brake oil pipe 6 is damaged, the inner wire 71 can continue to bear the tension due to the stop effect of the connecting piece 8b by the stopper portion 120b, so as to avoid the synchronous failure of the first brake generator 3 .

Thus, through the setting of the rocker lever 14, the end of the connecting piece 8c can be connected with the fixed frame 12c. resulting in linear slippage. Refer to Figure 17 to Figure 19 for the action diagrams on the interlocking side, and Figure 20 for the action diagrams on the non-interlocking side. The first brake operating module 1c does not have a groove 121 design, so the stopper 120c of the fixing frame 12c will directly touch the connecting piece 8c instead of being arranged at the bottom of the groove 121, and its function is still to be able to interfere when necessary The connecting piece 8c makes it stop producing displacement changes, so that the braking force of the second brake generator 4 will not increase excessively, so as to avoid the danger caused by the excessive force of the second brake generator 4 during the linkage braking; or, if When the brake oil pipe 6 is damaged, the inner cable 71 can continue to bear the tension due to the stop effect of the connecting piece 8c by the stopper portion 120c, so as to avoid the synchronous failure of the first brake generator 3 .

The module 2d can send hydraulic oil through the brake oil pipe 6 to the brake caliper 41 to generate braking force, and the rotation of the second rocker arm 23 can also synchronously drive the third rocker arm 24 to rotate, so that the second brake operation module 2d can send hydraulic oil through the brake oil pipe 6 until the brake caliper 41 generates a braking force. On the other hand, in the present utility model, an accommodating groove 215 is recessed on the side of the cylinder body 211, which accommodates a limit stopper 9, and the limit stopper 9 includes a stop block 91 and a spring 92 , used to limit the maximum pivotal displacement of the second rocker arm 23 . If this embodiment is compared with the foregoing first to fourth embodiments, the present embodiment replaces the stoppers 120, 120 of the aforementioned fixing brackets 12, 12a, 12b, 12c through the setting of the limit stopper 9. a, 120b, 120c effect, so the second rocker arm 23 of the present invention can interfere with the stop block 91 of the limit stopper 9 to stop the rotation when necessary, so as to avoid the occurrence of the first and second brakes Devices 3 and 4 are abnormal. Furthermore, the stop block 91 has at least one size length, and the stop block 91 of a specific size can be selectively selected. Therefore, for the brake master cylinders 21 of different models, the most suitable size and length of the stop block 91 can be selected during assembly, so that it has sufficient interference effect and can truly play the stop function.

As shown in Figure 22, in the first actuation state of the linkage side, the rider operates the first brake lever 11, so that the first rocker arm pulls the inner cable 71 to synchronously drive the brake arm 31, and then the brake shoe 33 is supported. Open and contact with the brake wheel drum 35, let the first brake generator 3 produce the braking effect.

As shown in Figure 23, in the second actuation state of the interlocking side, the rider continues to exert force on the first brake lever 11. At this time, the inner cable 71 still bears the pulling force and pulls the brake arm 31. The compression force that produces the reaction force pushes the first rocker arm 13d, and the connecting piece 8 connected with the first rocker arm 13d will be forced to produce a displacement change, and jointly make the second rocker arm 23 rotate and drive the third rocker arm 24 Pivot, and then push the plunger 212 to produce a displacement change, so that the second brake operating module 2d sends hydraulic oil through the brake oil pipe 6 to the brake caliper 41. At this time, the second brake generator 4 will generate a braking effect to achieve interlocking braking. effect.

As shown in Figure 24, in the third actuation state on the linkage side, the rider continues to apply force to the first brake lever 11 or when the brake oil pipe 6 is damaged, the reaction force generated by the bushing 72 at this time The first rocker arm 13d will continue to be pushed, so that the second rocker arm 23 will collide with the limit stopper 9 of the cylinder body 211 and stop rotating. Therefore, the second rocker arm 23 no longer continues to increase the force on the piston 212, so the braking force of the second brake generator 4 will not increase excessively, so as to avoid the excessive force of the second brake generator 4 during the interlock braking. the danger caused. Or, if the brake oil pipe 6 is damaged, because the second rocker arm 23 is stopped by the stopper 9, the inner wire 71 can continue to bear the pulling force, so as to avoid the failure of the first brake generator 3 synchronously.

Finally, as shown in Figure 25, under the actuation state of the non-linkage side, the rider operates the second brake lever 22 to make the second brake operating module 2 send hydraulic oil to the brake calipers 41 through the brake oil pipe 6. After receiving an oil pressure input, the brake caliper 41 clamps the brake disc 42 to restrict the rotation of the brake disc 42 to produce a braking effect.
