The invention discloses a wheel edge speed reducing and braking device. The device comprises a rack and a hub, a first-stage transmission assembly and a second-stage speed reducing assembly are arranged between the rack and the hub, a sun gear of the first-stage transmission assembly is connected with a motor through a half shaft, a first-stage inner gear ring is connected with the rack through aspline, and a first-stage planet carrier is connected with a second-stage sun gear. A second-stage planet carrier is fixedly connected with the rack; and the second-stage planet carrier is connected with a brake and an outer side sealing assembly, and an O-shaped ring and a shaft sleeve used for fixing the O-shaped ring are arranged between the rack and the motor. The wheel edge speed reducing andbraking device adopts a two-stage series structure, the transmission torque is sequentially increased, only the second-stage output torque is adopted, and the system complexity is reduced; the brakeis installed at the far end of a wheel edge speed reducer, the heat dissipation effect is good, and maintenance is convenient; two stages of transmission structures are floating structures, the uniform loading effect is good, no complex structural part exists, and the machining difficulty is reduced; and the half shaft is sealed in a static sealing manner, and the sealing reliability is remarkablyimproved.

    一种轮边减速及制动装置,包括机架和轮毂,机架和轮毂之间设有一级传动组件和二级减速组件,一级传动组件的太阳轮通过半轴连接有电机,一级内齿圈通过花键与机架连接在一起,一级行星架与二级太阳轮连接在一起,二级行星架与机架固定连接在一起;二级行星架连接有制动器和外侧密封组件,机架与电机之间设有O形圈和用于固定O形圈的轴套。本发明的轮边减速及制动装置采用两级串联结构,传递扭矩依次增大,仅第二级输出扭矩,降低了系统复杂度;制动器安装在轮边减速器的远端,散热效果好,维保方便;两级传动结构均为浮动结构,均载效果好,且无复杂结构件,降低了加工难度;半轴处密封为静密封形式,密封可靠性显著提高。
