Embodiment Construction

[0014] The present invention will be further described below in conjunction with implementation.

[0015] figure 1 Shown in is a cross-sectional structure diagram of a specific embodiment of the mechanical disc brake with a special-shaped disc spring of the present invention. For the convenience of description, the "left" and "right" referred to below are consistent with the left and right directions of the drawings themselves. When the brake handle is tightened to drive the pull rod 1 to rotate, the pull rod 1 drives the upper ejector rod 2 to rotate, and with the rotation of the upper ejector rod 2, the steel ball 3 rotates in the inclined spiral groove, pushing the lower top plate 4 and the right friction plate 5 advances to the left, and the spring pressure of the special-shaped disc spring 10 will be overcome when the lower top plate 4 advances, and the spring pressure of the special-shaped disc spring 10 is also the power of the lower top plate 4 resets. The big head s...

Abstract

The invention discloses a mechanical disc brake with an irregular disc spring. The mechanical disc brake comprises the irregular disc spring (10), a sealing sheet (7), a lower top tray (4) and a pincers body (11). A hole in gap matching with the lower top tray (4) is formed in the center of the irregular disc spring (10), elastic force of the irregular disc spring (10) is exerted on the lower top tray (4), an extending claw (15) extending from the center portion to the edge is arranged on the irregular disc spring (10), and the sealing sheet (7) is arranged under the irregular disc spring (10) and stuck on the pincers body (11). The mechanical disc brake is good in sealingness, miniature and light.

Description

technical field [0001] The invention relates to an important part of a bicycle and an electric bicycle, in particular to a cable mechanical disc brake. Background technique [0002] Bicycles and electric bicycles are a huge amount of transportation, walking and fitness tools in the world. In order to adjust the speed and brake, brakes are an essential part. What bicycle, electric bicycle brake commonly used at present used mechanical pull wire type brake. Chinese utility model patent ZL200420000667.3 bicycle disc brake device and Chinese utility model patent ZL200620013527.9 a bicycle disc brake device, the given mechanical disc brakes have adopted the spiral steel wire return spring as the main return spring, the current domestic and foreign markets Almost 100% mechanical disc brakes use a helical wire return spring as the main return spring. The disadvantages of this method are as follows: one is that the sealing is not good enough, and the other is that the height of th...
