The invention relates to a tire bead locking ring capable of preventing a tire from knocking over, in particular to a tire bead locking ring capable of ensuring that a tire bead does not slip towards the center of a rim when the tire is in a low-air-pressure or zero-air-pressure state. The tire bead locking ring 2 is a rubber circular ring located at the bottom of the rim 1, and the two ends of the circular ring abut against the inner side of the tire bead 3 to prevent the tire bead 3 from sliding. The wheel rim is characterized in that the outer surface of the circular ring is a plane, and the outer diameter phi Dh of the circular ring, the diameter phi D of the wheel rim and the height G of the wheel flange meet the condition that 1/2G < = 1/2 (phi Dh-phi D) < = G; the inner surface of the circular ring is attached to the rim, and two or more friction strips are arranged on the inner surface in the circumferential direction so that the friction force between the circular ring and the rim can be increased, and slippage between the circular ring and the rim can be prevented. Two ends of the circular ring are in contact with the tire bead, and the end material is soft to avoid damage to an airtight layer of the tire bead; the circular ring has enough compressive strength and rigidity in the axial direction, so that when the air pressure of the tire is reduced, the circular ring can abut against the tire bead without being damaged or deformed.
本发明涉及一种防止轮胎脱圈的胎圈锁止环,尤其涉及一种轮胎在低气压或零气压状态时,能够确保胎圈不向轮辋中心滑移的胎圈锁止环。所述胎圈锁止环2为一个位于轮辋1底部的橡胶圆环,圆环两端抵住胎圈3内侧,防止胎圈3滑移。其特征在于圆环外表面为平面,且圆环外直径φDh与轮辋直径φD和轮缘高度G之间满足条件:1/2G≤1/2(φDh‑φD)≤G;圆环内表面与轮辋贴合,且内表面上沿周向设置有两条以上的摩擦条,以增大与轮辋的摩擦力,防止圆环与轮辋之间发生滑移;圆环两端与胎圈接触,端部材料较软,以免破坏胎圈部气密层;圆环沿轴向方向有足够的受压强度和刚度,确保轮胎气压下降时,能够抵住胎圈而不发生破坏或变形。
