The invention provides a suspension device, a chassis and a mobile robot, and relates to the field of mobile devices. The suspension device comprises a driving wheel assembly, a universal wheel assembly, a first friction component and a second friction component, the first friction component is fixed to the universal wheel assembly, the second friction component is fixed to the driving wheel assembly, at least part of the first friction component is attached to the second friction component, and the driving wheel assembly is hinged to the universal wheel assembly. The first friction member is movable relative to the second friction member. When the suspension device is subjected to external impact, the universal wheel assembly and the driving wheel assembly tend to move relative to each other, so that a first friction component fixed on the universal wheel assembly and a second friction component fixed on the driving wheel assembly generate friction force, namely damping of relative movement of the universal wheel assembly and the driving wheel assembly. And the first friction component and the second friction component can stably output damping, and the running stability of the robot is improved.
本发明提供一种悬挂装置、底盘及移动机器人,涉及移动装置领域。悬挂装置包括驱动轮组件、万向轮组件、第一摩擦构件和第二摩擦构件,第一摩擦构件固定于万向轮组件,第二摩擦构件固定于驱动轮组件,第一摩擦构件的至少部分与第二摩擦构件贴合,驱动轮组件与万向轮组件铰接,以使第一摩擦构件能够相对第二摩擦构件移动。在悬挂装置受到外部的冲击时,万向轮组件和驱动轮组件出现相对运动趋势,即可使固定在万向轮组件上的第一摩擦构件与固定在驱动轮组件上的第二摩擦构件产生摩擦力,即为万向轮组件和驱动轮组件的相对运动的阻尼,第一摩擦构件和第二摩擦构件能够稳定输出阻尼,提升了机器人运行的稳定性。
