The invention discloses a sponge tire which comprises an outer tire and an airtight layer arranged in the outer tire, the airtight layer is used for being matched with a rim to form a closed air cavity, a sponge filling interlayer is formed between the airtight layer and the outer tire, and the sponge filling interlayer is filled with sponge. An airtight layer is arranged in a tire cavity of an outer tire to divide the tire cavity into a sponge filling cavity and a gas filling cavity, so that sponge only fills partial space of the tire cavity of the outer tire, the other space is filled with gas with certain pressure, and on the basis, the bearing capacity of the sponge tire is provided by the outer tire, the filling sponge and the gas jointly. By adjusting the inflation pressure in the closed air cavity, the bearing capacity of the sponge tire can be regulated and controlled, so that the reduction of the bearing capacity caused by plastic deformation and aging of the filling sponge is compensated, and the service life of the aircraft tire is prolonged. The invention provides a wheel comprising the sponge tire and a moving device.

    本发明公开一种海绵轮胎,包括外胎和设置于外胎内的气密层,气密层用于与轮辋配合形成封闭气腔,气密层与外胎之间形成海绵填充夹层,海绵填充夹层内填充有海绵。通过在外胎的胎腔内设置气密层,将胎腔分隔为海绵填充腔和气体填充腔,使得海绵仅填充外胎胎腔的部分空间,其余空间填充一定压力的气体,基于此,海绵轮胎的承载能力由外胎、填充海绵以及气体共同提供。通过调节封闭气腔内部的充气压力,可以实现对海绵轮胎的承载能力的调控,从而弥补由于填充海绵塑性形变和老化导致的承载能力的下降,进而延长航空轮胎的寿命。本发明提出一种包括上述的海绵轮胎的轮子和移动装置。
