The damping wheel comprises a mounting seat, a supporting leg and a wheel set, the upper end of the supporting leg is connected with the mounting seat through a first rotating shaft, the lower end of the supporting leg is hinged to the wheel set through a second rotating shaft, the mounting seat comprises a fixed part and a movable part, the upper end of the supporting leg is connected with the movable part, and an elastic space is arranged between the fixed part and the movable part at intervals. The movable part can move relative to the fixed part to expand and contract the elastic space, a pressure spring is arranged between the fixed part and the movable part to resist the movable part to compress the elastic space, an elastic piece is arranged between the fixed part and the movable part to resist the movable part to compress the elastic space, and the elastic piece comprises an elastic cushion block; when the wheel set bears external force, the external force is transmitted to the movable part through the supporting legs to compress the elastic space, and the end face of the elastic cushion block is stressed to elastically deform and resists the external force through elastic reset to release the elastic space. The end faces of the elastic cushion blocks are used for bearing force, pressure is borne through surface contact, stress can be balanced, and inclination or deformation caused by uneven local stress is effectively avoided.
本发明公开了一种箱包减震轮,减震轮包括安装座、支脚和轮组,支脚的上端与安装座通过第一转轴连接,支脚的下端与轮组通过第二转轴铰接,安装座包括固定部和活动部,支脚的上端与活动部连接,固定部与活动部之间间隔设有弹性空间,活动部能相对固定部活动以缩放弹性空间,固定部与活动部之间设有压簧以抵抗活动部压缩弹性空间,固定部与活动部之间设有弹性件以抵抗活动部压缩弹性空间,弹性件包括弹性垫块,轮组受外力作用时经支脚传导至活动部以压缩弹性空间,弹性垫块端面受力发生弹性形变并通过弹性复位抵抗外力作用以释放弹性空间。利用弹性垫块端面受力,通过面接触来承压,能够平衡受力,有效避免局部受力不均导致倾斜或变形。
