系统介绍

　　4Motion系统是大众车系中普遍采用的系统（类似于奥迪的Quattro），它是将动力根据前后50:50（正常的路面上可能不采用50:50的分配方式，而是90:10或者其他随附烈百于兰注策制分配方式）的形式分配给前苦政，后桥，并在必要不排凯破右时依靠系统会把百分之百的驱动力是附在一个车轮的动力上。动力分配

4motion

　　这就说明系统可以将0%到100%的动力输出到前或者后轴。所以在不同的路况下，它将随时调整分配个前后轴的动力比例，以适应各种路况。

技术核心

　　Haldex中央来自差速器

　　Haldex中央差速器至今已发展为360百科多片离合差速控制系统，通过机械装置与电控液压系统共同作用达局从氢说稳磁例克到智能分配扭矩的目的。这个多片离合器依车型不同而布置在不同的位置，有的靠近后桥差速则坐自复伯屋响因顺低器，有的类似于奥迪的方法与米甲送等处失任算影变速器融为一体。

　　其原理要向万生类似于手动挡汽车的离合器，只不过摩擦件帝温批乙校间的压紧力由弹簧力变成油液压力。基本结构为：输入轴末端通过花键与离合身难四清钟落器片径向固定；输出轴与壳体铸为一体，壳体内侧也安装了多片离合器片。扭矩的分配便是通过油压对离合器片的作用来实缩因叶先史了右教创任判现，油压的高低决定了分配扭矩的大小，而油压则是通过ECU控制电算食现需石领座别磁阀产生的。有了ECU，至于何时何地分配多少扭矩到各个车轮年与粉，自然也就变得简单。[1]

When a vehicle traveling in the urban areas when the normal road, basically the same as before and after the shaft rotational speed, the computer will be 90% of the power output to the front, leaving only 10% to th强卷子蒸慢场e rear axle.
