The operation of the two-shaft two-lever caliper brake will now be described.
In operation, a brake cable is installed through adjusting screw 22 in the setscrew 13 to connect to the right brake fork 17. When the user grips the bicycle brake handle, the brake cable pulls the right brake fork 17, so that the right brake fork 17 moves around the first shaft rod 18 through the connection of the connecting bar 5, and simultaneously, the second shaft rod 15 moves towards the center, and the right brake shoe assembly 12R moves towards the steel ring.
Meanwhile, the left brake fork 9 also moves towards the center by taking the point B as a fulcrum, so that the left brake shoe component 12L moves towards the steel ring. When the left brake shoe assembly 12L contacts the rim, braking operation is initiated. The spring 6 is reset when the bicycle brake handle is released. The right brake fork 17 and the left brake fork 9 are simultaneously reset to the initial state under the connection of the connecting bar 5 to complete one braking operation.
The right fork 17 and the left fork 9 of the double-shaft caliper brake are mounted together with a first shaft 18 as a center. When the brake is operated, the right brake fork 17 takes the second shaft rod 15 as an axis, the left brake fork 9 takes the first shaft rod 18 as an axis, and the right brake fork 17 and the left brake fork 9 both take a point B as a fulcrum. This configuration increases the length of the assist arm and decreases the length of the power arm. By utilizing the double-shaft double-lever structure, the force transmission ratio is greatly increased, the braking force is improved by 20 percent compared with that of a brake with a single-shaft structure, and a rider can achieve an ideal braking effect with smaller braking force.
It should be noted that the linkage plate 19 and the left brake fork 9 rub against each other during operation, and in order to increase the contact surface of the fulcrum B, the portion of the linkage plate 19 in contact with the left brake fork 9 is machined to avoid the phenomenon that the punched fracture surface is inclined during punching production.
In addition, the linkage plate 19 and the right brake fork 17 can be welded together, so that the structure of the parts is simplified.
Without being limited thereto, any changes or substitutions which are not thought of through creative efforts should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
