The invention discloses a driving shaft assembly of a hand brake. Comprising a transmission shaft, a planetary gear train, a first-position clutch mechanism and a second-position clutch mechanism, the two ends of the transmission shaft are installed on the hand brake shell through bearings, and a transmission gear is fixedly installed on the transmission shaft. The planetary gear train is located at the position of a transmission gear of the transmission shaft and comprises a gear ring fixed to the hand brake shell, a planet carrier arranged on the transmission shaft in a sleeving mode and three sets of planetary gears meshed with the gear ring and the transmission gear. The first-position clutch mechanism is located at the thread position of the transmission shaft and is of a friction clutch structure. The two-position clutch mechanism is located at the position of a polished rod on the rear portion of the transmission shaft and is of an embedded type rapid clutch structure. And the pinion is a hand brake driving output wheel. A planetary gear train structure is adopted in the hand brake driving shaft assembly, coaxial amplification of input force by the hand brake driving shaft is achieved, multi-time amplification of the input force is achieved through a small space, and different transmission multiplying power can be obtained by adjusting tooth number configuration of a planetary gear train.

    本发明公开了一种手制动机主动轴组成。包括传动轴和传动轴上依次设置的行星轮系、一位离合机构、二位离合机构;传动轴两端通过轴承安装于手制动机壳体上,传动轴上安装固定有传动齿轮;行星轮系位于传动轴传动齿轮位置,包括与手制动机壳体固定的齿圈,套装在传动轴上的行星架,三组与齿圈和传动齿轮啮合的行星齿轮;一位离合机构位于传动轴螺纹位置,为摩擦离合结构;二位离合机构位于传动轴后部光杆位置,为嵌入式快速离合结构;小齿轮为手制动机驱动输出轮。本发明手制动机主动轴组成采用行星轮系结构,实现了手制动机主动轴对输入力的同轴放大,利用较小的空间实现了输入力的多倍放大,且通过调整行星轮系的齿数配置,可获得不同的传动倍率。
