The invention discloses a pneumatic tire capable of automatically supplementing air, an air supplementing device is arranged on a tire body, the air supplementing device comprises an air supplementing cavity, an air supplementing one-way valve and an air inlet one-way valve, the air supplementing cavity is arranged on the tire body in an elastic deformation manner, the air outlet end of the air supplementing one-way valve is communicated with an inner cavity of the tire body, and the air inlet one-way valve is communicated with the air inlet one-way valve. The air inlet end of the air inlet one-way valve is communicated with the air supply cavity, the air inlet end of the air inlet one-way valve is communicated with the outside, the air outlet end of the air inlet one-way valve is communicated with the air supply cavity, when the tire body rotates, the air supply cavity can be acted to be subjected to compression deformation or deformation recovery, and when the air supply cavity is subjected to compression deformation, the air inlet end of the air inlet one-way valve is closed. When the tire body is deformed, air in the air supply cavity enters the tire body in a one-way mode through the air supply one-way valve, when the air supply cavity recovers deformation, due to the fact that large pressure difference exists between the air supply cavity and the outside world, outside air enters the air supply cavity in a one-way mode through the air inlet one-way valve, and automatic air supply can be conducted on the tire body in the using process by adopting the structure.

    本发明公开了一种可自动补气的充气轮胎,在轮胎本体上设有补气装置,该补气装置包括补气腔、补气单向阀和进气单向阀,所述补气腔可弹性形变地设置于轮胎本体上,所述补气单向阀的出气端与轮胎本体内腔连通,且补气单向阀的进气端与补气腔连通,所述进气单向阀的进气端与外界相通,进气单向阀的出气端与补气腔连通,当轮胎本体在转动过程中,则会作用补气腔使之压缩形变或恢复形变,且当补气腔被压缩形变时,位于补气腔内的气体则通过补气单向阀单向地进入轮胎本体内,当补气腔恢复形变时,由于补气腔与外界存在较大的压力差,故外界空气通过进气单向阀而单向进入补气腔内,故采用本发明结构在使用过程中可对轮胎本体进行自动补气。
