图 1A示出了是具有 8个圆球型气室 4的内胎结构， 其中， 每个球型气室 4与圆环气 室 5a之间至少设置有一个通气孔 45， 图 3A示出了具有一个通气孔 45的结构， 该通气孔 45将圆环气室 5a与球型气室 4连通， 该通气孔 45的位置只要是在圆环气室 5a与球型气 室 4之间的隔壁层上即可。 如图 5A所示， 所述圆环气室 5a和 8个与之贯通的球型气室 4 形成一独立的整体气室，采用该贯通连接而成的整体气室， 即圆环气室 5a实质上起到一个 将各个球型气室 4连通在一起的一个连续的贯通管道， 该连续的贯通连接比非贯通连接相 比具有抗拉强度高、 稳定性好的特点。
制作本发明图 1A所示的内胎， 先将每个球型气室 4单独制造后， 再将各个球型气室 4 开孔后贯穿在圆环气室 5a的外壁上， 圆环气室 5a起到连通每个球型气室 4的作用， 圆环 气室 5a与球型气室 4之间的固定连接采用热熔连接而成； 每个球型气室 4与圆环气室 5a 之间的隔壁层上至少加工出一个通气孔 45，借助该通气孔 45使圆环气室 5a与贯穿在其上 的每个球型气室 4形成一个独立的整体气室， 即防爆内胎气室。 其中圆环气室 5a的粗细 尺寸及排数是由爆胎后所受的拉力和轮毂 8的规格而定。 如图 7所示， 若采用橄榄型的球 型气室 4， 则最好采用两个等径且圆环回转轴线重合的圆环气室 5a， 所述的两个圆环气室 5a的外壁上共同套装有若干个 （图 7A中示出了 8个） 均布的球型气室 4， 在每个橄榄型 的球型气室 4与所述两个圆环气室 5a之间均分别设置有一个通气孔 45， 所述两个圆环气 室 5a和 8个同时与该两个圆环气室 5a贯通的球型气室 4形成一独立的整体气室， 即用双 排圆环气室 5a将各个橄榄型球型气室 4贯通，采用并排圆环气室可以进一步加强球型气室 4的连接强度， 在并排的每一圆环气室 5a上， 在每个球型气室 4与每个圆环气室 5a之间 留有通气孔将该两个圆环气室 5a和球型气室 4相通。 每个圆环气室 5a的粗细尺寸应既不 影响防爆内胎套入轮毂 8， 又要能承受爆胎后的拉力。 此外， 球型气室 4为圆球型时， 也 可以采用两排等径且圆环回转轴线重合的圆环气室 5a与球型气室 4贯通形成一独立的整体 气室。 如图 6A所示， 圆环气室 5a的环形内径要略大于轮箍 8的外轴肩直径； 该内胎要求 承受的气压应与外胎相同， 一般为 0. 2〜0. 4MPa。
制作本发明图 1B、 图 2、 图 3B、 图 4B、 图 5B的内胎， 先将球型气室 4单独制造后再 与连通管 5b热熔连接而成， 形成一个独立的整体气室， 即防爆内胎气室 2。 如图 6B,连通 管 5b的粗细尺寸是由爆胎后所受的拉力和轮毂 8的尺寸所决定。 要求连通管 5b的粗细尺 寸既不影响防爆内胎套入轮毂 8， 又能承受爆胎后的拉力。 防爆内胎要求承受的气压一般 为 0. 2〜0. 4MPa与外胎相同。 如图 7B所示， 若采用橄榄型的球型气室 4， 则最好采用两排 等径且圆环回转轴线重合的连通管 5b， 所述两排连通管 5b和 8个同时与该两排连通管 5b 连接的球型气室 4形成一独立的整体气室， 即用双排连通管 5b将各个橄榄型球型气室 4 连接， 采用并排连通管可以进一步加强球型气室 4的连接强度。 此外， 球型气室 4为圆球 型时， 也可以采用两排等径且圆环回转轴线重合的连通管 5b与球型气室 4连接形成一独 立的整体气室。
图 4、 图 5分别是将图 1所示两种内胎安装到轮毂上的轴向位置示意图及 A-A剖切位 置的剖视图， 从图 4A、 5A中可以看出， 将本发明第一种内胎安装在轮箍 8上后， 圆环气 室 5a (或连通管 5b， 如图 4B、 5B所述的第二种充气式汽车防爆轮胎）起到连通和固定各 个球型气室 4的作用。 如图 6A所示， 由球型气室 4和圆环气室 5a连接后组合成的本发明 充气式汽车防爆内胎，其中两个气室（即有圆环气室 5a和球型气室 4构成的内胎气室和外 胎气室 6 ) 都有各自独立的气嘴 （即内胎气嘴 3和外胎气嘴 1 ) 充气， 图 6B示出由球型气 室 4与舰管 5b组合成的本发明的充气式汽车防爆内胎， 其中两 ^室（内胎气室 2和外胎气室 6)都由各自独立的气嘴（内胎气嘴 3和外胎气嘴 1 )充气。 当上述两种汽车轮胎安装时， 内胎 安装在外胎 7与轮毂 8之间的空间里， 应先安装外胎 7的一侧再将防爆内胎从轮毂 8的另 一侧装入， 然后将外胎 7的剩余一侧安装好即可。轮胎充气时， 必须先充内胎， 后充外胎。 外胎气室 6与内胎气室应具有同样的气压。 当外胎 7漏气减压时， 外胎 7的胎壁就会贴敷 在内胎球型气室 4上， 由于每个球型气室 4的外壁是不连续的， 所以， 此时轮胎的继续行 驶就会发生车体震动， 从而提醒驾驶员及时发现轮胎气压不足。 当外胎突然爆胎时， 可由 内胎来支撑， 用内胎来防止高速行驶的汽车外胎爆胎时， 造成汽车突然倾斜， 从而导致驾 驶员因反应不及时而酿成的惨重事故。在外胎爆胎时，虽然会造成轮胎乃至车体的震动感， 但该内胎由于有圆环气室 5a (或连通管 5b)支撑着球型气室 4，依靠着本发明内胎的支撑， 可以避免突然爆胎后会出现的由于车体大幅度的倾斜而引发的生命危险。 需要特别强调的 是： 汽车轮胎的气压应定期用气压表检测， 检测操作步骤应和充气时一样， 以防由于不能 及时发现内胎的气压不足， 爆胎时会影响防爆内胎发挥其积极作用。
本发明充气式汽车防爆内胎具有高弹性、有良好的绝缘性能和机械强度， 耐水、耐热、 耐磨、 抗老化、 抗静电、 耐化学腐蚀、 耐油及一般溶剂， 耐稀酸、 碱。 密度为 1. 35克 /立 方厘米， 使用温度 -60〜100°C。
本发明充气式汽车防爆内胎还可应用于飞机、 装甲车等交通工具的轮胎内， 起到防爆 胎的作用和提高其安全可靠性。 防爆内胎的材料还可使用热塑性弹性体， 塑料， 树脂等材 料制作。
尽管上面结合图对本发明进行了描述， 但是本发明并不局限于上述的具体实施方式， 上述的具体实施方式仅仅是示意性的， 而不是限制性的， 本领域的普通技术人员在本发明 的启示下， 在不脱离本发明宗旨的情况下， 还可以作出很多变形， 这些均属于本发明的保 护之内。
