轮胎是指在各种车辆或机械上装配的接地滚动的圆环形弹性橡胶制品。它通常安装在金属轮毂上，能支承车身，缓冲外界冲击，实现与路面间的接触并保证车辆的行驶性能。轮胎是车辆的重要组成部件之一，它的主要功能是支撑车体重量，传送牵引和制动的扭力，保证车轮与路面的附着力。
目前的轮胎主要分为充气轮胎和实心轮胎两种，充气轮胎的弹性好、质量轻，但存在漏气和爆胎现象；实心轮胎避免了漏气和爆胎现象，耐磨性强，使用寿命较长，但存在防震能力差和质量重的问题。
有鉴于此，本发明人提出以下技术方案。

进一步而言，上述技术方案中，所述第一减震腔室及第二减震腔室的横截面均呈直角三角形，其相互对称分布。
进一步而言，上述技术方案中，所述第一减震腔室与第二减震腔室之间形成有环形隔板，该环形隔板与所述橡胶胎体内侧面中部一体固定，且该环形隔板位于该第二通孔与第一通孔之间。
进一步而言，上述技术方案中，所述第一通孔和第二通孔均为圆柱孔。
进一步而言，上述技术方案中，所述橡胶胎体内壁成型有凸环部，且该凸环部两侧 均形成有阶梯槽；该橡胶胎体安装于轮毂上后，该凸环部置于轮毂外围的槽体中，并被挤压变形。
进一步而言，上述技术方案中，所述凸环部的宽度大于轮毂外围的槽体的宽度。
进一步而言，上述技术方案中，所述橡胶胎体外表面设置有复数防滑凸起或防滑槽。
采用上述技术方案后，本发明与现有技术相比较具有如下有益效果：本发明在橡胶胎体内部成型有至少两个相互隔绝的第一减震腔室和第二减震腔室，在与轮毂装配后形成两个密闭的气囊结构，不仅结构强度大，承重能力强，且弹性形变能力强，以致具有极强的减震抗震能力，另外，橡胶胎体离开与之碰撞的外物后，该橡胶胎体能够马上恢复，使用起来极为方便。
