Description

一种防滑链 技术领域
本发明涉及汽车用品领域，具体涉及一种防滑链。
背景技术
为了使汽车在冰雪路面上正常行驶，一般给轮胎配备防滑链，以此来增大与路面的摩擦力。现有的防滑链一般包含铁锁链式与橡胶网格式，铁锁链式防滑链虽然承载能力大、防滑效果好，但是重量也较重，噪音非常大，车辆在运行中轮胎的颠簸尤为明显，长时间使用后，铁锁链与轮胎间的磨损较大，造成轮胎的非正常磨损。再有橡胶网格式防滑链具有重量轻、安装方便的优点，但是随着行驶里程的增加，橡胶网格的磨损就会增大，磨损达到一定程度，容易会造成防滑链松动继而断裂，而且橡胶网格防滑链由于网格密度一致，在行驶时会形成固定频率的噪音，影响驾驶员感官。另外橡胶网格内容易被冰雪附着，并导致摩擦力下降，降低防滑效果。
发明内容
本发明的目的在于提供的一种汽车防滑链，以解决上述背景技术中传动防滑链笨重难安装、噪音大强度低、导致轮胎非正常磨损及挂冰的问题。
为实现上述目的，本发明提供的防滑链主要由若干链节相互连接构成的链圈。链节包括链杆、背板和防滑齿。链杆为弧形结构，链杆的一端沿圆弧径向设有开槽，开槽内设有连接开槽两侧的链轴。链杆的另一端设有宽度与开槽宽度对应的连接头。连接头设有轴线与链轴轴线平行的孔。链杆在圆弧外侧连接设有与链杆中部相切的背板。背板在与链杆连接的另一面延链杆圆弧周向设有若干防滑齿。
优选的，活接为其中一个链节的链杆沿圆弧周向排列设有第一挂钩和第二挂钩。
优选的，背板设有若干贯通孔。
优选的，胶垫为实心圆柱体，圆柱体一端同轴设有销。胶垫通过销与背板的销孔连接。
优选的，防滑齿为不等节距设置。
优选的，带铁芯的初级线圈，初级线圈设置在车轮拱内部靠近轮胎面的一侧，初级线圈与车辆电源电性连接。背板设有带铁芯的次级线圈，次级线圈输出端设有稳压电路。
优选的，防滑齿内设有电加热体，电加热体与电压整流电路电性连接。
优选的，防滑齿中央部位设有与背板平行的贯通孔。
优选的，防滑齿与背板铰接。防滑齿的一侧还设有磁体。背板中央设有电磁铁，电磁铁与稳压电路电性连接，电磁铁还并联设有电容器。
优选的，车轮提升器包括：筒座、桶芯及螺杆。筒座为竖直的方管结构，方管的底部设有支撑底座。方管侧壁铰接有齿尖朝内上方的棘牙，棘牙尾部设有翘板。方管内部设有可上下移动的筒芯，筒芯外侧壁设有与棘牙配合的倒齿。筒芯内部设有带外螺纹的螺杆，筒芯顶部设有壳体，壳体内设有与螺杆外螺纹配合的涡轮，壳体内部的一侧设有与涡轮配合蜗杆，壳体侧壁设有与蜗杆对应的轴孔。摇把通过轴孔与壳体内部的蜗杆连接。螺杆顶部设有托架，托架的顶端设有胶垫。
本发明的有益效果：根据车轮大小将适当数量的链节首尾连接，并通过活接构成链圈安装在轮胎排水槽内，并通过车轮碾压，链节背板的防滑齿刺破冰面从而提高了轮胎的摩擦力。当轮胎由于磨损导水槽逐渐变浅时，为了消除背板与胎面的缝隙，将胶垫通过销固定在背板的销孔中，通过胶垫来填补背板与胎面的间隙，从而保证防滑链的正常工作。由于链节的防滑齿间距各不相同，所以在行驶时，防滑齿碾压路面时的发声间隔不通，因此不能形 成固定的噪音频率，从而达到降噪的作用。当有冰渣附着在防滑齿上时，通过对防滑齿加热，使其融化脱落，保证防滑齿工作正常。另外，当安装有该防滑链的汽车在干燥的铺装路面上行驶时，可将防滑齿放平收纳，以便较小行驶噪音，延长使用寿命，保护路面。本发明还包括了快速车轮提升器，其通过棘牙伸缩结构可快速适应车轮高度，并通过顶部托架在螺杆作用下直接将车轮升起，免去了普通千斤顶先消除减震行程，再升车轮的过程。

具体实施方式
下面将结合本发明实施例中的附图进行详细描述。
请参阅图1、图2、图3、图4、图5、图6、图7、图8、图9、图10、图11，一种防滑链，其特征在于：是由若干链节1相互连接构成的链圈。链节1包括链杆2、背板3和防滑齿4。链杆2为弧形结构，链杆2的一端沿圆弧径向设有开槽5，开槽5内设有连接开槽5两侧的链轴6。链杆2的另一端设有宽度与开槽5宽度对应的连接头7。连接头7设有轴线与链轴6轴线平行 的轴孔8。链杆2在圆弧外侧连接设有与链杆2中部相切的背板3。背板3在与链杆2连接的另一面，延链杆2圆弧周向排列设有若干防滑齿4。活接9为其中一个链节1的链杆2沿圆弧周向排列设有第一挂钩10和第二挂钩11。背板3设有若干贯通挂孔12。胶垫13为实心圆柱体，圆柱体一端同轴设有连接销14。胶垫13通过连接销14与背板3的挂孔12连接。防滑齿4为不等间距设置。带铁芯的初级线圈15设置在车轮拱内部靠近轮胎面的一侧，初级线圈15与车辆电源电性连接。背板设3有带铁芯的次级线圈16，次级线圈16输出端设有稳压电路17。防滑齿4内设有电加热体18，电加热体18与稳压电路17电性连接。防滑齿4中央部位设有与背板3平行的贯通孔。防滑齿4与背板3铰接；防滑齿4的一侧还设有磁体21；背板中央设有电磁铁19，电磁铁19与稳压电路17电性连接，电磁铁19还并联设有电容器20。
本发明还提供一种为快速安装防滑链的车轮提升器，其主要包括：筒座22、桶芯23及螺杆24。筒座22为竖直的方管结构，方管的底部设有支撑底座。方管侧壁铰接有齿尖朝内上方的棘牙25，棘牙25尾部设有翘板。方管内部设有可上下移动的筒芯23，筒芯23外侧壁设有与棘牙25配合的倒齿26。筒芯23内部设有带外螺纹的螺杆24，筒芯23顶部设有壳体27，壳体27内设有与螺杆24外螺纹配合的涡轮28，壳体27内部的一侧设有与涡轮28配合蜗杆29，壳体27侧壁设有与蜗杆29对应的轴孔。摇把30通过轴孔与壳体27内部的蜗杆29连接。螺杆24顶部设有托架32，托架32的顶端设有胶垫33。
工作原理：首选根据车轮圆周大小将适当数量的链节1通过链轴6及轴孔8的配合连接起来，并将链一端的连接头7与活接9的链轴6配合，组成一条完整的防滑链。将防滑链缠绕嵌入轮胎排水槽中，将活接9的第一挂钩10通过钳子钩挂在防滑链末端链轴6上，此时防滑链安装完毕。
在使用过程中随着轮胎胎面的逐渐磨损，轮胎排水槽会逐渐变浅，从而 影响防滑链的稳定性。此时需要活接9一端的第二挂钩11重新钩挂在防滑链末端的链轴6中达到紧固的目的。同时，将胶垫13一端的连接销14从胎面方向向外穿入背板3的挂孔12中，固定在背板3与胎面之间的胶垫13起到消除间隙的作用，从而保证防滑链的稳定工作。
由于链节的防滑齿4间距各不相同，所以在行驶时，防滑齿4碾压路面时的发声间隔不同，不能形成固定的噪音频率，因此达到降噪的目的。
当安装有该防滑链的汽车在冰雪路面上行驶时，对车轮拱处的初级线圈15加电，此时初级线圈15在一定范围内形成电磁场。由于轮胎不断旋转，背板3上的次级线圈16不断切割轮拱处的电磁场，致使次级线圈16感应发电。次级线圈16发出的电流经过稳压电路17后使防滑齿4内的电加热体18发热，融化防滑齿4上的附着冰，从而达到自清洁的目的。同时，电磁体19工作，产生与防滑齿4上磁体21同极的磁场，通过斥力将方滑齿4沿铰接轴推开，并进入工作状态。由于电磁铁并联有电容器20，在稳压电路17对电磁铁19加电的同时也将电量储存在电容器20中，当次级线圈16随着车轮转动远离初级线圈15后，电容器20仍能为电磁铁19提供一个稳定的工作电流，使防滑片4保持在工作位置。
当安装有该防滑链的汽车在干燥的铺装路面上行驶时，停止对轮拱处的初级线圈15供电，此时电容器20的电量逐渐被电磁铁耗尽后，防滑齿4上的磁体21与电磁铁吸合，防滑齿4沿铰接轴折叠收纳到背板3上。
为了更方便快速的将防滑链安装在轮胎排水槽中，将车轮提升器的摆放在轮胎的外侧放稳，将筒芯从筒座中拉出，使托架定在车轮轮岡内臂，此时筒芯在倒齿和棘牙的作用下不会回落。旋转摇把通过蜗杆涡轮的传动，将螺杆向上旋出，并带动车轮上升。
最后应说明的是：以上所述仅为本发明的优选实施例而已，并不用于限 制本发明，尽管参照前述实施例对本发明进行了详细的说明，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，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
