一种多重弹性支撑的电摩力车胎 技术领域
本发明涉及免充气轮胎，特别涉及一种多重弹性支撑的电摩力车胎。
 背景技术
目前的免充气轮胎已广泛地应用于汽车、电动摩托以及自行车上，而传统的免充气轮胎一般为橡胶实心轮胎，虽然具有载荷大，耐磨性能好，使用寿命长的优点，但其同样由于为实心的轮胎，不可避免地带来重量以及舒适性的问题，而为了改善传统的免充气轮胎的问题，目前的做法是采用中空的免充气轮胎或在免充气轮胎外加装充气装置，而中空的免充气轮胎虽然减轻了轮胎的重量，但往往支撑强度不够，而在实心的免充气轮胎上加装充气装置 ，虽然增加了弹性性能，轮胎重量过大的问题没有解决，另外其不可避免也存在传统的充气轮胎所存在的问题。
因此，亟需一种既能减轻轮胎重量，同时又能兼具高弹性和高支撑强度的免充气轮胎。
 技术问题
本发明要解决的技术问题是提供一种多重弹性支撑的电摩力车胎，该力车胎采用中空的椭圆体相接而成，既节省了材料，又能具备高舒适性和高支撑硬度。
 技术解决方案
为了解决上述技术问题，本发明的技术方案为一种多重弹性支撑的电摩力车胎，包括由外至内依次相接的胎面、第一椭圆体层、第二椭圆体层以及第三椭圆体层，第一椭圆体层、第二椭圆体层以及第三椭圆体层均由中空的椭圆体环绕胎面轴心连接而成，同一椭圆体层中相邻的椭圆体相交并于相交位置处贯通，第一椭圆体层和第二椭圆体层中椭圆体呈对位相交并于相交位置处贯通，第二椭圆体层和第三椭圆体层中椭圆体呈错位相交并于相交位置处贯通，第一椭圆体层、第二椭圆体层以及第三椭圆体层中椭圆体的长轴均与胎面轴向线平行，第一椭圆体层、第二椭圆体层中椭圆体的长轴长度均大于第三椭圆体层中椭圆体的长轴长度，第三椭圆体层中的两个椭圆体与相邻的第二椭圆体层中的椭圆体交汇位置向内凸出并相接形成加强筋，胎面与第一椭圆体层的表面相接。

 本发明的实施方式
下面结合附图对本发明的具体实施方式作进一步说明。在此需要说明的是，对于这些实施方式的说明用于帮助理解本发明，但并不构成对本发明的限定。此外，下面所描述的本发明各个实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互组合。
如图1、图2、图4所示，一种多重弹性支撑的电摩力车胎，包括由外至内依次相接的胎面1、第一椭圆体层2、第二椭圆体层3以及第三椭圆体层4，第一椭圆体层2、第二椭圆体层3以及第三椭圆体层4均由中空的椭圆体环绕胎面轴心连接而成，同一椭圆体层中相邻的椭圆体相交并于相交位置处完全贯通，完全贯通的意思是指两个椭圆体相交时，于相交位置的边沿线形成通孔，相交部分则去除掉。第一椭圆体层2和第二椭圆体层3中椭圆体呈对位相交并于相交位置处贯通，对位相交则是指第一椭圆体层2和第二椭圆体层3中相对位置的椭圆体的中心与胎面轴心位于同一直线上。第二椭圆体层3和第三椭圆体层4中椭圆体呈错位相交并于相交位置处贯通，即第三椭圆体层4中一个椭圆体与第二椭圆体层3中的两个椭圆体分别相交，而相交位置处也呈完全贯通的状态。第一椭圆体层2、第二椭圆体层3以及第三椭圆体层4中椭圆体的长轴均与胎面1轴向线平行，即表示椭圆体均是于短轴所对应的表面位置相交，而非是长轴所对应的椭圆体表面。由于椭圆体相交时，相交位置均完全贯通，所以第一椭圆体层2、第二椭圆体层3以及第三椭圆体层4相交形成内部中空的交联空间，而为了进一步加强该交联空间的支撑力度，第三椭圆体层4中的两个椭圆体与相邻的第二椭圆体层3中的椭圆体交汇位置向内凸出并相接形成加强筋5。
如图2所示，第一椭圆体层2、第二椭圆体层3中椭圆体的长轴长度均大于第三椭圆体层4中椭圆体的长轴长度，此时的第三椭圆体层4一方面是作为轮毂连接部的功能，另一方面也是作为受力的传递点。作为轮毂连接部，第三椭圆体层4长轴的长度可以根据轮毂连接位的要求进行设计，而作为受力传递点，其与第二椭圆体层3的连接位置处设置有加强筋5，可以增强其支撑强度，并增强整个轮胎内部的交联结构，使轮胎的内部更加地稳固。当然，第三椭圆体层4中椭圆体的长轴长度也不能太短，至少为第二椭圆体层3中椭圆体长轴长度的1/2,过于短会造成第三椭圆体层4硬度大，无法提供适当的缓冲。
如图5所示，为进一步增强相邻椭圆体间的连接强度和支撑强度，在对位或错位相交的椭圆体的相交位置处可以作圆滑过渡处理，这个圆滑过渡无论是位于椭圆体的内表面还是外表面，当两个椭圆体相接时，相接位置的内外表面均作圆滑过渡处理，即把相接位置的锐角或钝角直接处理成弧线，这样即使在短时间内受力过大，连接处的圆滑过渡处理也可以保证连接处不会发生断裂。
而本实施例的胎面1与第一椭圆体层2的外表面相接，此处的外表面是以胎面1轴心为中心点去界定的，第一椭圆体层2中远离胎面1轴心的为外表面。而胎面1上设置有凹槽，此处设置的凹槽的具体搭配并没有严格的限定，只要其有利于防滑和降低胎面1的硬度，增强胎面1的舒适性即可。而本实施例也提供一种具体的凹槽的搭配，如图3所示，本实施例于胎面1设置的凹槽包括横向凹槽11、斜向凹槽12以及十字形凹槽13，其中横向凹槽11设置于第一椭圆体层2中相邻的椭圆体相交位置对应的胎面1上，并且横向凹槽11是沿胎面1的弧线间隔设置，胎面1弧线是指由胎面1轴向线所在的平面切割胎面1后形成截面的表面弧线，横向凹槽11的数量有三个，以这三个横向凹槽11为一排，胎面1上等距离间隔地分布着多排横向凹槽11。而在同一侧的靠近胎面1边沿的相邻的横向凹槽11间设置有十字形凹槽13，由于胎面1边沿是相对的，所以十字形凹槽13呈对称设置。而相邻的两排横向凹槽11之间还设置有交叉的斜向凹槽12，该交叉的斜向凹槽12位于两排横向凹槽11中处于中间位置的横向凹槽11之间，而十字形凹槽13以该交叉的斜向凹槽12的交叉点为对称中心。而由于横向凹槽11刚好是位于第一椭圆体层2中两个相邻的椭圆体相交位置对应的胎面1弧线上，而在该胎面1弧线上靠近边沿处刚好是两个椭圆体相交的凹位，因此此处的胎面1厚度较大，才能保护与该凹槽完全贴合，由于此处胎面1厚度大，其硬度也大，所以在接触地面时，舒适性仍有进一步改善的空间。因此，可在此处位置的的横向凹槽11设计成凹槽深度由靠近边沿开始，沿凹槽走向，逐渐变小。这样靠近边沿处的深度大，等于是胎面1变薄，有利于此处受力后的弹性形变。
由于轮胎在接触地面的过程中，摩擦时间长，因此发热量也大，而为了将热量散发出去，可以在第三椭圆体层4上靠近胎面1轴心的位置设置通孔41，通孔41在轮胎受挤压发生弹性形变时，可以将热量从通孔41处排出，该通孔41的设定位置不作要求，但最有利于排出热气的位置是通孔41的中心与第二椭圆体层3中相邻的两个椭圆体相交位置相对。
作为进一步对椭圆体层弹性和支撑强度的改进，可以将第一椭圆体层2、第二椭圆体层3以及第三椭圆体层4的壁厚依次变小。
为保证轮胎的硬度和耐磨性，胎面1、第一椭圆体层2、第二椭圆体层3以及第三椭圆体层4的材料均为邵氏硬度为55A-60D的高分子聚合物，而本实施例选择的是聚氨酯材料，聚氨酯一方面具有良好的耐磨性，另一方面也同时具备良好的耐热性，当然本实施例中提到的聚氨酯只是作为一个具体的例子，并不是作为限定只能使用聚氨酯，只要其硬度达到要求，基本上所有的高分子聚合物材料均可以作为本发明力车胎的材料。
本实施例的多重弹性支撑的电摩力车胎可由注塑一体化成型，形成一体化结构。此结构在行驶过程中更加稳定，同时也更加耐用。
另外，本发明对椭圆体层中椭圆体的数量并不是只有附图中所展现的一种，椭圆体层中椭圆体的数量可以为7-120个，即数量可以为7、20、50、60、80、100、120等等，在此不作列举，而即使由不同数量的椭圆体组成，只要其中椭圆体的数量在限定的范围内，其都依旧满足作为电摩力车胎的指标要求。
以上结合附图对本发明的实施方式作了详细说明，但本发明不限于所描述的实施方式。对于本领域的技术人员而言，在不脱离本发明原理和精神的情况下，对这些实施方式进行多种变化、修改、替换和变型，仍落入本发明的保护范围内。
