Description
本实用新型涉及汽车配件领域的轮胎,特别是涉及不爆轮胎。
现如今,生产汽车所装配的轮胎多为无内胎轮胎,与有内胎轮胎相比,其安全性能显著提高,行驶过程中,轮胎与地面摩擦产生的热量,可以通过轮辋直接散热,散热性能好,可以大大降低爆胎的机率;另外,有内胎轮胎在被刺扎后漏气很快,而无内胎轮胎由于有一层用特种丁基橡胶混合物制成的气密层,在被刺扎后漏气缓慢。
但是轮胎内壁的气密封只有在穿孔尺寸在小范围时能自行带合穿孔,尺寸稍大些便难以黏合。此时,轮胎漏气严重受到压力的影响,进而引起爆胎。
爆胎是指轮胎在极短的时间,因破裂突然失去空气而瘪掉的现象。有关统计数据显示,在高速公路上的交通事故中,10%是由于轮胎故障引起的,而其中爆胎一项就占轮胎故障引发事故总量的70%以上。这种偶然事件难以防控,对人们的生命安全产生了极大的威胁。
发明内容
为了能够避免轮胎在行驶途中因为尖锐物体刺破轮胎而发生爆胎事故,本实用新型提供了不爆轮胎。该实用新型通过在轮胎内径开口处增设弹性界膜将其密封,并在轮胎内密封腔内充满弹性充气的微气囊构成在弹性微气囊体,解决轮胎不爆的技术问题。
本实用新型解决技术问题所采用的方案是:
不爆轮胎,其特征在于:在轮胎内径开口处封合设有弹性界膜,弹性界膜与轮胎内腔构成封闭的微气囊腔,微气囊腔内填满有弹性微气囊体。
为了进一步解决本实用新型所要解决的技术问题,本实用新型提供的不爆轮胎中,所述弹性界膜,为环状弹性体可延展及收缩,设在轮胎内径开口处,弹性界膜左右两侧与轮胎内径开口处封合。
优选的,所述弹性微气囊体,是由若干微气囊之间相互连接构成不可分离的整体,所述微气囊壁具有弹性,所述微气囊内部填充有气体。
优选的,所述微气囊腔,是由弹性界膜内壁与轮胎内腔体所构成的密封的环状空腔。
优选的,所述不爆轮胎在安装时,弹性界膜的界膜外壁与车轮上的轮辋凹槽形成密闭的充气空腔。
优选的,所述轮辋凹槽上设有气门孔。
优选的,所述弹性界膜,为弹性材料。
积极效果:
1、本实用新型在轮胎胎体内设有微气囊腔,在微气囊腔内填充弹性微气囊体,当尖锐物体刺破轮胎时,仅刺破个别微气囊体,因微气囊之间彼此独立,刺破泄漏少量胎内空气,即使刺破界膜到充气空腔,因充气空腔占整个轮胎体积比很小,只是轮胎略瘪,不会因突然失 去空气而瘪掉的。保障了人员的安全性,并且不会影响车辆的正常行驶。具有安全性,稳定性。
2、本实用新型在因漏气对轮胎维护时,因弹性微气囊与弹性界膜具有弹性及封闭性,无需拆卸修补,仅需要通过气门孔向充气空腔内充气增压,便可使轮胎恢复到预定胎压,省时省力提高了效率。
3、本实用新型没有改变原有轮胎的外部整体结构,安装方便,适用于现有车轮的轮毂与轮辋。适用范围广,有利于推广。
因而适宜作为不爆轮胎使用。

下面将结合本实用新型实施例中的附图,对本实用新型实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本实用新型一部分实施例,而不是全部的实施例。尽管已经示出和描述了本实用新型的实施例,对于本领域的普通技术人员而言,可以理解在不脱离本实用新型的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型,本实用新型的范围由所附权利要求及其等同物限定。基于本实用新型中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本实用新型保护的范围。
据图所示,不爆轮胎,其特征在于:
在轮胎内径开口1处封合设有弹性界膜2,弹性界膜2与轮胎内腔构成封闭的微气囊腔3,微气囊腔3内填满有弹性微气囊体4。
所述弹性界膜2,为环状弹性体可延展及收缩,设在轮胎内径开口1处,弹性界膜2左右两侧与轮胎内径开口1处封合。
所述弹性微气囊体4,是由若干微气囊之间相互连接构成不可分离的整体,所述微气囊壁具有弹性,所述微气囊内部填充有气体。
所述微气囊腔3,是由弹性界膜2的界膜内壁2.1与轮胎内腔体所构成的密封的环状空腔。
所述不爆轮胎在安装时,弹性界膜的界膜外壁2.2与车轮上的轮辋凹槽6形成密闭的充气空腔5。
所述轮辋凹槽6上设有气门孔7。
所述弹性界膜2,为弹性材料。
安装过程
首先,将微气囊腔内填充满弹性微气囊体。
其次,将弹性界膜封闭,将不爆轮胎安装到车轮的轮辋上。
最后,通过气门孔向充气空腔内充气并测压,调解充气空腔与微气囊腔内的气压达到预定胎压后结束充气,完成安装。
工作原理:
安装本轮胎的汽车,在行驶过程中遇到尖锐物体刺穿轮胎等造成轮胎漏气的情况时。
破裂的仅是微气囊腔内的若干个弹性微气囊,损失的是破裂的弹性微气囊内的空气,不会使轮胎内部的空气瞬间释放从而对轮胎内的气压产生影响引发爆胎,造成车辆行驶的安全隐患。
当微气囊腔内的弹性微气囊破损过多,造成胎压不足时。通过设置在轮辋凹槽上的气门孔向充气空腔内充气加压,使得弹性界膜向微气囊腔内延展鼓起,挤压微气囊腔内部的弹性微气囊气囊体中的每个弹性微气囊,改变每个微气囊的体积,使其相互挤压发生形变后重新恢复预定胎压,从而调整轮胎的胎压恢复到预定胎压。
最后应说明的是:以上所述仅为本实用新型的优选实施例而已,并不用于限制本实用新型,尽管参照前述实施例对本实用新型进行了详细的说明,对于本领域的技术人员来说,其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换,凡在本实用新型的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本实用新型的保护范围之内。
