1/8全独立悬挂攀爬越野车

预计尺寸在1/8或者1/10～这个尺寸的轮胎轮毂标准件选择非常多
全独立悬挂和直桥优点各不相同最终我还是选择了全独立想尽办法加大行程

要想行程大摆臂不可短
下摆臂的轴间距到了极限
行程最大可达到65mm （接近半个轮胎的高度）

转向的角度也不能小当然要还有阿克曼角经计算外转45度内转35.3度

由于行程非常大，于是借鉴大s结构将轮胎轴向后移动了8.5mm 这样就保证了万向节始终不超过45度的范围。

转向部分用了轮边减速结构提高了通过性同时减少了传动轴的压力一举两得并且加入了9度内倾角转向效果更好

桥总成的样子（画了好久改了好多遍）

转向上面费劲了心思也是花费时间最长的部分经过了多次的计算才确定了图中红色摆臂的位置……是因为要保证舵机在角度不动时摆臂上下运动对轮胎转向造成的偏移误差最小（市面上的大脚车这种现象非常严重）一开始舵机根本没地方放 https://app.rcfans.com/public/emotion/face_umm.png后来改了又改才确定了现在的位置

大概这个样子前轮也有8度后倾角

波箱也要自己做刚买了齿轮还没到等等等……………….
