[0030] 一种球面关节履带链, 包括履带板组件以及连接履带板组件的链节 2。 如图 3-4 , 履带板组件包括履带板 11、 履带板安装件 12、 侧限位件 13。 履带板 11为条形 的板状结构, 根据不同的履带轮胎的尺寸结构履带板 11可以具有不同的长、 宽 、 弯曲度等结构参数。 板状的履带板 11的一侧具有沿履带板的长度方向设置的 、 凸出于履带板表面的条状的防滑条 111, 防滑条表面还设有防滑凸起 1111以提 高履带链与地面的附着力。 履带板 11表面的结构、 材料以及结构和材料的组合 可以根据履带行驶结构的行驶、 应用环境做出相应的调整。 履带板安装件 12包 括一板状结构, 板状结构的两端朝着中间部分弯折成钩状凹口。 该板状结构的 中间部分的直板作为履带板附接部 121, 板状结构两端的钩状结构作为履带连接 部 122。 履带板安装件 12有两个, 两个履带板安装件分别位于履带板 11的两端, 履带板 11的端部附接至履带板附接部 121的外表面。 如图 4, 链节 2包括两个链节 连接部 21以及将链节连接部 21串接以形成一环状结构的串接部 22。 链节连接部 2 11为朝向环状的链节 2内部的球状凸起或者近球状凸起, 履带连接部 122的钩状 结构的内表面具有一球状或者近球状内凹。 凸起能够起恰好容纳在凹口中平滑 滚动。 如图 5-6, 侧限位件 3包括上连接部 31、 侧连接部 32、 限位部 33。 上连接部 31为板状结构, 侧连接部 32同样为垂直于设置在上连接部 31两端部的板状结构 。 限位部 33设置在两个侧腰部之间, 并且连接两个侧连接部 32和上连接部 31。 履带链的组装过程为: 链节 2从履带板安装件 12的两个履带板连接部之间的幵 口套入, 使得链节 2的链接连接部 21的凸起置于履带板连接部 122的凹部中。 履 带板安装件 12的每个履带板连接部都套入一个链节 2中。 链节 2的另外一个链节 连接部套入与该履带板安装件相邻的另一个履带板安装件的履带板连接部中。 然后, 将侧限位件的上连接部 31附接至履带板附接部 121的内表面, 使得位于上 连接部 31两侧的侧连接部 32垂直于上连接部 31并且由上连接部 31延伸至履带板 连接部之外, 上连接部 31两侧的所述侧连接部 32包括向内凹陷的腰部, 所述履 带板连接部 122与侧连接部 32的腰部焊接连接, 以使得侧连接部 32和凹口形成封 闭的环, 将将链节 2限位在钩状的履带板连接部 122中。 限位部 33在上连接部 31 的底边连接两侧的侧连接部 32并沿着侧连接部 32的长度方向延伸至履带板安装 件的两个履带板连接部 122之间的幵口之外。 链节连接部 21可以为球状结构, 或 者是靠近链节 2内部的侧面为球面或者近球面的柱状结构。 履带板 11的同一侧端 的履带安装件 12通过链节 2连接形成可装配在履带轮胎侧面的封闭链环结构, 如 图 7。 当履带链装配到履带轮胎的侧面后, 侧限位件 3的上连接部抵靠在履带轮 胎的用于与地面接触的表面, 履带限位件 3的限位部 33的底面贴合在履带轮胎的 侧壁上, 防止履带链与履带轮胎脱离。 限位部 33的底面形状可以根据履带轮胎 的结构、 材料等属性合理设计。 履带板连接部在平行于链节连接部的底面的平 面内具有内凹的弧形缘边 1221, 链节连接部 21在同一平面内具有与履带板连接 部配合的外凸的弧形边缘 211, 如图 8所示, 使得履带板安装件 12能够随着履带 板连接部 122在履带轮胎的转动平面内转动。 同吋, 履带板连接部 122在垂直于 的底面的平面内具有内凹的弧形缘边 1222, 链节连接部同一平面内具有与履带 板连接部匹配的外凸的弧形边缘 212, 如图 9所示, 使得履带板安装件能够随着 履带板连接部以链节连接部 21在与地面平行的水平面 (即履带轮胎的转弯平面 ) 内转动。 因此, 当履带行走机构转弯吋, 履带板安装件与链节由靠近转弯外 侧的一端逐渐向靠近转弯内侧的一端靠拢吋, 履带板连接部与链节连接部的贴 合位置, 沿着它们在转弯平面内形成的弧形轨迹移动, 不会发生如图 2中所示的 碰撞, 能够实现更小的转弯角度, 并且转弯灵活。
[0032] 另外, 也可以将履带板连接部和链节连接部的结构可以对调, 即履带板连接部 为具有凸起结构而链节连接部具有与履带板连接部匹配的内凹结构。 使得履带 板连接部 122和链节连接部 21采用凹凸整个面接触, 轮胎转角更大, 而且长吋间 使用不会磨坏钩状的履带连接部 122的内表面。
[0033] 如图 10-13, 履带板安装件 12包括一板状结构, 板状结构的两端朝着中间部分 弯折成钩状凹口。 该板状结构的中间部分的直板作为履带板附接部 121, 板状结 构两端的钩状结构作为履带连接部 122。 履带板安装件 12有两个, 两个履带板安 装件分别位于履带板 11的两端, 履带板 11的端部附接至履带板附接部 121的外表 面。 如图 4, 链节 2包括两个链节连接部 21以及将链节连接部 21串接以形成一环 状结构的串接部 22。
[0034] 履带板连接部 122的钩状结构的内表面具有一球状或者近球状的凸起, 链节连 接部 211的朝向环状的链节 2的内侧表面具有一球状或者近球状内凹。 履带连接 部 122的凸起能够起恰好容纳在链节连接部 211的凹口中平滑滚动。 链节 2从履带 板安装件 12的两个履带板连接部之间的幵口套入, 使得履带板连接部 122的凸起 置于链接连接部 21的凹部中。 履带板安装件 12的每个履带板连接部都套入一个 链节 2中。 链节 2的另外一个链节连接部套入与该履带板安装件相邻的另一个履 带板安装件的履带板连接部中。 然后, 将侧限位件的上连接部 31附接至履带板 附接部 121的内表面, 使得位于上连接部 31两侧的侧连接部 32垂直于上连接部 31 并且由上连接部 31延伸至履带板连接部之外, 上连接部 31两侧的所述侧连接部 3 2包括向内凹陷的腰部, 所述履带板连接部 122与侧连接部 32的腰部焊接连接, 以使得侧连接部 32和钩状结构形成封闭的环, 将将链节 2限位在钩状的履带板连 接部 122中。 限位部 33在上连接部 31的底边连接两侧的侧连接部 32并沿着侧连接 部 32的长度方向延伸至履带板安装件的两个履带板连接部 122之间的幵口之外。 链节连接部 21可以为柱状结构, 并且该柱状结构的靠近链节 2内部的侧面为内凹 的球面或者近球面。 履带板 11的同一侧端的履带安装件 12通过链节 2连接形成可 装配在履带轮胎侧面的封闭链环结构, 如图 7。 当履带链装配到履带轮胎的侧面 后, 侧限位件 3的上连接部抵靠在履带轮胎的用于与地面接触的表面, 履带限位 件 3的限位部 33的底面贴合在履带轮胎的侧壁上, 防止履带链与履带轮胎脱离。 限位部 33的底面形状可以根据履带轮胎的结构、 材料等属性合理设计。 履带板 连接部在平行于链节连接部的底面的平面内具有外凸的弧形缘边 1221, 链节连 接部 21在同一平面内具有与履带板连接部配合的内凹的弧形边缘 211, 使得履带 板安装件 12能够随着履带板连接部 122在履带轮胎的转动平面内转动。 同吋, 履 带板连接部 122在垂直于的底面的平面内具有外凸的弧形缘边 1222, 链节连接部 同一平面内具有与履带板连接部匹配的内凹的弧形边缘 212, 使得履带板安装件 能够随着履带板连接部以链节连接部 21在与地面平行的水平面 (即履带轮胎的 转弯平面) 内转动。 因此, 当履带行走机构转弯吋, 履带板安装件与链节由靠 近转弯外侧的一端逐渐向靠近转弯内侧的一端靠拢吋, 履带板连接部与链节连 接部的贴合位置, 沿着它们在转弯平面内形成的弧形轨迹移动, 不会发生如图 2 中所示的碰撞, 能够实现更小的转弯角度, 并且转弯灵活。
虽然结合附图描述了本发明的实施方式, 但是本领域普通技术人员可以在所附 权利要求的范围内做出各种变形或修改。
