Abstract： |
The present invention is a type of shoe-drum brake including a multi-freedom cooperating-shoe mechanism and a gap automatic-adjusting mechanism. Each cooperating-shoe mechanism is composed of two multi-freedom shoe assemblies, these shoe assemblies cooperate with each other. Each brake shoe of shoe assembly is hinged to its drive arm which is hinged and supported on a brake base plate. The multi-freedom cooperating-shoe mechanism also co-operates with said gap automatic-adjusting mechanics. The present brake can simultaneously enhance brake effect and reliability, improve the abilities of heat-resistance, wet-degeneracy resistance and the distribution uniformity of the friction assistant pressure, prolong the using life, automatically adjust the gap between of frictional members and realize perfect performance. |
