The invention provides a driving wheel assembly and a fire-fighting robot. The driving wheel assembly comprises an elastic wheel composed of a wheel body and a wheel shaft, wherein the wheel body is provided with a wheel shaft hole; a connecting shaft assembly, wherein the assembly comprises a connecting shaft, a first pin shaft and a transition shaft sleeve, a first mounting hole is formed in oneend of the connecting shaft, the other end of the connecting shaft is inserted and fixed into the wheel shaft hole, a first through hole is formed in the side wall of the first end of the transitionshaft sleeve, the first end of the transition shaft sleeve is arranged in the first mounting hole in a clearance mode, and the first end of the transition shaft sleeve is hinged to the connecting shaft through a first pin shaft; a motor assembly comprising a motor, wherein a motor shaft of the motor is inserted into the second end of the transition shaft sleeve and is in driving connection with the second end of the transition shaft sleeve. Compared with a motor shaft, the connecting shaft assembly in the technical scheme forms a cross-shaped connecting shaft system used for transmitting torque and having flexibility, so that two functions of impact resistance and torque force transmission are realized, the structure of the robot is more compact, and the space is saved.
本公开提供了一种驱动轮组件及消防机器人,驱动轮组件包括:由轮体和轮轴组成的弹性轮,轮体上设置有轮轴孔;连接轴组件,包括连接轴、第一销轴和过渡轴套,连接轴的一端上设置有第一安装孔,连接轴的另一端插入并固定到轮轴孔内,过渡轴套的第一端侧壁上设有第一通孔,过渡轴套的第一端间隙安装在第一安装孔内,过渡轴套的第一端和连接轴通过第一销轴进行铰接;电机组件,包括电机,电机的电机轴插入到过渡轴套的第二端内,并与过渡轴套的第二端驱动连接。该技术方案的连接轴组件相对电机轴来说就构成了一个既能够用来传递扭矩又具有柔性的十字连接轴系统,这样便实现了抗冲击和传递扭矩力两种功能,从而使得机器人的结构更紧凑,节省了空间。
