Problems solved by technology

If it is applied to the normally closed brake, the push rod of the pusher extends to the set position, and the brake in the normally closed state is released. When the push rod retracts back to the position, the normally closed state of the brake part is restored. Braking, when the pusher realizes the operation of the braking process, it can only make the braking part produce a one-time braking of the reset normally closed state

Abstract

A superimposed braking driver of a normally closed type brake comprises a driver (1), the external end of a push rod (7) is used for connecting a driving arm (8) in a braking part by hinge shaft so as to act on the braking part (9), a superimposed braking mechanism which can lead the braking part to realize superimposed braking is arranged, and the superimposed braking mechanism acts on the braking arm (10) in the braking part (9) by a corresponding component; the superimposed braking mechanism can adopt a plurality of structures like a superimposed braking mechanism (11a) or a superimposed braking mechanism (11b) or a superimposed braking mechanism (11c). By operating the driver (1) individually, the openness and restoration of the normally closed brake can be realized, and according to requirement, the superimposed braking mechanism can be operated individually to realize the superimposed brake; and the working process of the openness and restoration of the normally closed brake can be applied to a working condition with frequent braking individually to lead the normally closed brake and the superimposed brake to be in a working process of a braking mode, and can be applied to a more stable and reliable braking.

Description

technical field [0001] The invention relates to a brake, in particular to the improvement of a normally closed brake pushing device, which is suitable for normally closed brakes such as tile-type and disc-type structures. Background technique [0002] The brake is mainly composed of a braking part and a pusher or a pushing device. The publication date is August 22, 2007, and the patent document with the publication number CN2937582 discloses (application number 200620050535.0) a "variable force pusher for brakes". The driving arm is hingedly connected to act on the braking part, so that the braking part realizes the working state. The structure of the pusher includes a driving device, a liquid pump driven by the driving device, a liquid storage tank, and a hydraulic cylinder. The non-driving liquid chamber of the cylinder communicates with the liquid storage tank. If it is applied to the normally closed brake, the push rod of the pusher extends to the set position, and th...
