Auxiliary braking thrust of the brake system and auxiliary braking method of brake

摘要

Disclosed is a supplementary braking thrust apparatus for a brake, comprising a thruster (1). A push lever (7) of the thruster (1) acts on a brake unit (9). The supplementary braking thrust apparatus of said brake further comprises a supplementary braking mechanism, and the supplementary braking mechanism acts on a brake arm (10) to realize supplementary braking. Also, disclosed is a supplementary braking method of a brake, comprising the following steps: applying a braking action to the brake arm (10) using the thruster (1); and applying a further braking action to the brake arm (10) using the supplementary braking mechanism to obtain supplementary braking of the brake.
