Description

防弹、 防爆轮子
本发明所属技术领域
本实用新型涉及用于在地面上支承车辆并使其运动的防弹、 防爆 轮子， 特别适用于高速行驶的车辆。
在本发明之前的现有技术
我们知道， 汽车在路面上高速行驶时， 最怕的情况之一是轮胎发 生 "爆胎"现象， 特别是车辆的前轮轮胎， 若汽车高速行驶时发生 "爆胎"现象， 重则车毁人亡， 轻则车损人伤。 车辆使用的轮子由轮 毂、 轮辋、 轮辐、 轮胎和气门芯组成， 轮胎一般由内胎、 外胎组成， 当外胎被扎伤或遭到硬物击伤时， 内胎很容易破碎而出现 "爆胎"现 象， 为克服上述不足， 人们取消了内胎将轮胎制成不需要充气的 "实 心"式， 但 "实心"轮胎的不足是弹性差， 对车辆的减振性差， 不适 用高速行驶的车辆， 所以人们发明了"无内胎式子午胎" ， 既取消了内 胎、 减振性又好， 且不易发生 "爆胎"现象而得到广泛应用， 但当轮 胎被严重扎伤或遭到硬物严重击伤及轮胎遭到枪击时， 仍会出现 "爆 胎"现象， 特别是当轮胎使用一段时间后， 由于磨损更易发生 "爆 胎"现象， 从而导致交通事故。
发明目的
本实用新型的目的是提供一种当轮胎发生 "爆胎"现象时， 可使 车辆和司乘人员安然无恙的一种防弹、 防爆轮子。
本发明的技术方案
本实用新型是通过如下措施达到： 一种轮子， 设有轮毂、 轮辋、 轮辐、 子午胎和气门芯， 其特征是： 子午胎内的轮毂上设有备份胎。
本实用新型的其它有利结构形成从属权利要求的对象。 上述所说的备份胎为一环形胎， 其断面呈梯形， 外缘设有与普通 轮胎外缘功能相同的胎紋， 一般采用橡胶制成。
上述所说的备份胎为开口环形实心胎体， 备份胎开口处设有连接 件， 备份胎经连接件与轮毂相连接， 连接件上可以设有调节装置， 以 调节环形实心胎体的直径的大小， 使同一备份胎能适应不同直径的轮 毂。
为了使本实用新型中备份胎与轮毂结合得更紧密， 防止轮子在高 速旋转时， 备份胎与轮毂之间产生离心力， 可以在备份胎内设有钢 带， 钢带的两端分别与连接件相连接， 也可以在备份胎外设有钢带， 钢带的两端分别与连接件相连接。
本实用新型由于在子午胎内的轮毂上设有备份胎， 当子午胎受到 外力作用出现 "爆胎"现象时， 备份胎支撑轮胎在车辆不减速的情况 下继续安全行驶， 即使轮胎爆裂后全部脱落， 因为备份胎的外缘设有 与普通轮胎外缘功能相同的胎紋也可以照常行驶。 既保证了车辆和司 乘人员的安全， 也保证了 "爆胎" 的轮胎及轮毂不因高速碾压而报 废。
附图说明
附图是本实用新型的结构示意图， 也是一种实施例的结构示意 图。
图 1是本实用新型的结构示意图。
图 2是本实用新型备份胎的一种结构示意图。
实施例
下面结合附图对本实用新型作进一步描述： 一种轮子， 设有轮毂、 轮辋、 轮辐、 子午胎和气门芯、 其结构及 它们相互之间的连接关系、 连接方法与现有技术相同， 此不赘述。
如图 1所示， 本实用新型在子午胎 1内的轮毂 2上设有备份胎 3， -备份胎 3为一环形胎，-其断面呈梯形， 一般采用橡胶制成。
如图 2所示， 备份胎为开口环形实心胎体， 备份胎开口处设有连 接件 4， 备份胎经连接件与轮毂相连接， 连接件上可以设有调节装置， 以调节环形实心胎体的直径的大小， 使同一备份胎能适应不同直径轮 毂， 为了使本实用新型中备份胎与轮毂结合得更紧密， 防止轮子在高 速旋转时， 备份胎与轮毂之间产生离心力， 可以在备份胎内设有钢带 5， 也可以在备份胎外设有钢带 5， 钢带 5的两端分别与连接件 4相连 接。 钢片 6起定位作用。
本实用新型安装过程是： 先将子午胎的一边安装在轮辋上， 然后 将备份胎与轮毂相结合， 经备份胎上的钢带和连接件使其与轮毂结合 得更紧密， 防止轮子在高速旋转时备份胎与轮毂之间产生离心力， 再 将子午胎的另一边安装在轮毂上， 最后经气门芯向子午胎内充气至一 定气压即可。
一、 结构、 原理： '
安装在原车子午胎里面， 不破坏汽车的原有结构， 对驾驶无任何 影响， 高度略低于子午胎胎面内层的用橡胶及其他材料制成的实心结 构； 当车辆突然爆胎时子午胎内备份胎能支撑起汽车。
二、 功能- 不怕刺扎、 不怕枪弹， 最显著的功效是不怕高速爆胎。 避免由于 爆胎发生危险事故， 既保护了人的安全又保护了轮胎和轮毂， 属主动 防护性安全设施。 三、 使用寿命：
安装于轮胎内部， 老化程度极其缓慢， 寿命可达 15年以上。 即便 汽车轮胎磨损严重需要更换轮胎， 也无需更换备份胎， 可再次安装在 …新的轮胎里面继续使用。 - 四、 应用范围 "
可广泛应用于各种无内胎的车辆， 特别适应于军、 警、 运钞等专 用车辆高速行驶及经常性行驶于恶劣路况下的特殊车辆。 有极强的防 弹、 防爆功能。 '
五、 成本：
该产品制造成本很低， 安装了该产品后就可省去备用轮胎， 增大 储物箱空间， 对整车来讲， 成本反而降低了很多。
六、 特点：
该产品可安装在任何的轮毂。 轮毂、 轮胎及车辆的任何部位都不 用改变。
