A mechanical disc brake with an unlocking ring

Abstract

The invention discloses a mechanical disc brake with an unlocking ring. The mechanical disc brake comprises a brake pad, a movable disc, a stationary disc, cheese head screws, an external main body, a nylon plastic part, an adaptor, a fine tuning spring, a draft arm, a dustproof plastic cover and an unlocking ring, wherein the stationary disc is arranged at the left side of the external main body; the movable disc is arranged at the left side of the stationary disc; the brake pad is arranged at the left side of the movable disc; the unlocking ring and a second magnet are arranged between the brake pad and the movable disc; the adaptor is arranged at the bottom of the external main body; a fine tuning plastic sleeve is arranged on the external main body at the right side of the adaptor; the fine tuning spring is arranged in the fine tuning plastic sleeve through a fine tuning screw; the draft arm is arranged at the right side of the external main body through a draft arm locking screw; a return spring is arranged between the draft arm and the external main body; and the dustproof plastic cover is arranged at the right side of the draft arm. The mechanical disc brake disclosed by the invention has the advantages of simple structure, convenience in use, low cost and simplicity in mounting; and the mechanical disc brake has a good unlocking action for blocking conditions of a single-acting type mechanical disc brake.

Description

technical field [0001] The invention relates to an unlocking device, in particular to a mechanical disc brake with an unlocking ring. Background technique [0002] At present, single-action mechanical disc brakes are popular in the market, accounting for more than 90% of the low-end and low-end markets, such as figure 1 As shown, in the existing single-action mechanical disc brakes that are popular on the market, the moving disc 6 is in direct contact with the brake pad 3. When braking, due to the relatively large friction between the brake pad 3 and the moving disc 6, the Make the moving disc 6 unable to recover, and cause it to be stuck, and general manufacturers use to reduce the contact surface between the moving disc 6 and the brake pad 3 to remove the stuck phenomenon, but in the actual test, there are still stuck phenomena. Contents of the invention [0003] The object of the present invention is to provide a mechanical disc brake with an unlocking ring with low co...
