The invention discloses an electrically-driven hand brake, which belongs to the technical field of rail transit braking and comprises a hand brake body and a driving device assembly. The hand brake body comprises a hand wheel, a brake main shaft and a brake device assembly. The driving device assembly comprises a motor mechanism and a speed reducing mechanism, and the driving device assembly is arranged between the hand wheel and the braking device assembly. According to the electrically-driven hand brake, the integrated design is adopted, the motor mechanism and the speed reducing mechanism are reasonably arranged between the hand wheel and the brake device assembly, and compared with an externally-hung motor scheme, the requirement for extra installation space is avoided, and the overall size of the hand brake is greatly reduced. According to the integrated design, the output power of the motor mechanism directly acts on the braking main shaft through the speed reducing mechanism, a reversing device and other connecting parts which need to be additionally arranged due to the design of an externally-hung motor are omitted, and therefore the system structure is simplified, meanwhile, energy loss caused by multiple connecting links is avoided, and efficient and stable torque transmission is achieved.
本发明公开了一种电驱动手制动机,属于轨道交通制动技术领域,包括手制动机体以及驱动装置总成。手制动机体包括手轮、制动主轴以及制动装置总成。驱动装置总成包括电机机构以及减速机构,驱动装置总成设置于手轮与制动装置总成之间。电驱动手制动机采用集成设计,将电机机构和减速机构合理布局于手轮和制动装置总成之间,相较于外挂式电机方案,避免了额外的安装空间需求,大幅降低了手制动机的整体体积。集成化设计将电机机构的输出动力通过减速机构直接作用于制动主轴,省去了因外挂电机设计需额外设置的换向装置及其它连接部件,从而简化了系统结构,同时避免了因多个连接环节带来的能量损失,实现了高效、稳定的扭矩传递。
