Description

一种新型珠子链 技术领域
本发明涉及应用于车辆轮胎的防滑装置，其用于增加对例如冰或雪覆盖的道路的附着力，并且尤其涉及一种新型珠子链。
背景技术
授权公告号CN 1623810 B，授权公告日2010年05月12日的发明专利公开了一种轮胎所用的低干涉牵引装置，提供一种轮胎防滑链设计方案。其在轮胎的内侧面和外侧面都进行固定，能适应较小的间隙，同时不会牺牲防滑链的强度和完整性。该防滑链的过渡链由防滑件(钢板卷制滚珠或者钢丝卷制弹簧)，钢丝绳和连接件组成。过渡链和侧链(绳)通过连接件连接。车辆行驶或珠子链在使用时，防滑件对钢丝绳的挤压和磨擦作用以及在轮胎侧面的收紧器通过连接件对钢丝绳两端的拉紧作用，容易造成钢丝绳的断裂。不仅影响了防滑链的使用效果、减少了钢丝绳的使用寿命，而且如果断裂发生在车辆的高速行驶过程中还会造成车辆的损坏或者引起驾驶事故。
发明内容
本发明基于上述技术问题提供一种可有效缓解过渡链根部位置的钢丝绳受到的应力作用的新型珠子链，使过渡链钢丝绳的寿命延长2-5倍,也即使整个防滑装置的寿命延长2-5倍。
一种新型珠子链，包括横向设置的两条侧绳、纵向设置在两条侧绳之间的过渡链、连接所述侧绳和所述过渡链的连接件；所述侧绳的两端设有第一连结组件；其中一条侧绳的某处断开，断开位置处设有第二连结组件；所述过渡链包括设有防滑件的钢丝绳、设于所述钢丝绳两端的安装件，所述安装件通过所述连接件与所述侧绳连接；所述连接件包括分设于所述第二连结组件两侧的第一连接件和设于另一条侧绳上与所述第二连结组件相对的第二连接件；其特征在于：所述过渡链包括连接于所述第二连结组件两侧的减应力过渡链，两条所述减应力过渡链一端的安装件与所述第二连接件连接，两条所述减应力过渡链另一端的安装件分别与所述第二连结组件两侧的两个第一连接件连接；任意一条所述减应力过渡链上全部防滑件沿所述钢丝绳的移动空间小于除所述减应力过渡链以外任意一条过渡链上的全部防滑件沿所述钢丝绳的移动空间。
作为优选，所述减应力过渡链的钢丝绳包括减应力段，所述减应力段分别位于所述钢丝绳的两端；所述减应力段的外端设置所述安装件，所述减应力段的内端固定设有限位件，所 述防滑件设于所述限位件之间。
作为优选，所述减应力段的长度为15mm-70mm。
作为优选，所述防滑件滑动设置于所述减应力过渡链的两端减应力段之间的钢丝绳上，所述限位件的外径大于所述防滑件的内径。
作为优选，所述限位件沿所述钢丝绳方向的长度为5mm-25mm。
作为优选，除所述减应力过渡链以外任意一条过渡链具有与所述剪应力过渡链相同的结构。
作为优选，所述限位件为金属圆环或其它异型环。
作为优选，所述防滑件包括钢板卷制滚滑动件或钢丝卷制弹簧。
作为优选，还包括收紧装置，所述收紧装置包括具有弹性的收紧环、以及沿所述收紧环的周边设置的多个收紧环连接件；所述收紧环连接件用于连接所述侧绳，使得使用中在轮胎侧面形成封闭绳圈的侧绳，受到朝向封闭绳圈内部的向心收紧力。
作为优选，所述过渡链呈Z字形设置在两条侧绳之间。
设于所述第二连结件两侧的过渡链，其根部贴近安装件的钢丝绳不仅受到防滑件在车辆行驶时向此处反复挤压带来的交变应力作用和摩擦作用，而且还受到所述第二连结件因为其刚性结构造成侧绳局部变形带来的切向方向的锁紧应力作用，多方向的应力同时作用于过渡链根部贴近安装件的钢丝绳，使得该处的钢丝绳受到的应力剧增，所以极容易断裂。本发明中，在减应力过渡链的两端贴近所述安装件的根部预留出一定长度的减应力段，将原本集中于该部的应力转移分散至整个减应力段的各部分，同时减少防滑件与钢丝绳的摩擦，从而大大缓解了钢丝绳在该部受到的集中应力。本发明中，在减应力过渡链设置限位件，将其防滑件的活动范围限定在两端的限位件之间，使得所述防滑件与所述钢丝绳在贴近所述安装件的根部隔离，既避免了防滑件对钢丝绳上该部的挤压和摩擦，又给于该部钢丝绳较大的自由变形空间从而转移和分散由于侧绳设置刚性的第二连结组件变形而带来的对两侧过渡链端部增大的应力。经申请人有关技术人员的反复实验，本发明的新型珠子链，使得钢丝绳的使用寿命延长了2-5倍。
综上所述，本发明通过在所述第二连结件的两侧设置减应力过渡链，在所述减应力过渡链的两端设置限位件，使得所述防滑件与所述钢丝绳在贴近所述安装件的根部隔离，减少防滑件与钢丝绳的摩擦。所述减应力过渡链的减应力段将原本集中于钢丝绳在贴近所述安装件的根部位置处的应力转移分散至整个减应力段的各部分。延长了钢丝绳的使用寿命。同时，还具有结构简单、性能稳定、安装方便、制作成本低等优点。
