自制贯穿式碳板3D打印幽灵小蛋性能桥
之前做的老车幽灵r1性能虽然不错，但是原厂幽灵桥蛋实在太大了，很容易卡。于是自学Solidwords，尝试自己设计一款小蛋幽灵桥。http://image.rcfans.com/pic/20221112/1668213598182886296.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
3d打印的最大缺点就是不结实，所以加一块4mm厚的碳板贯穿整条桥。打印件更多是装饰和固定轴承的作用，真正受力的是碳板。伞齿用二代的，蛋可以小一圈。散件和组装好的样子：

除了c座，其他打印件用黑色树脂，优点是便宜和表面细腻，缺点是不能攻牙，所以主要用m2.5防滑螺母来固定，确保不滑丝。

输入轴小伞齿上扬8度，传动更顺。

转向方面，主轴内倾8度，后倾10度，阿尔曼角5度，外侧最大转向50度。

为了低重心，舵机下沉、电池下沉，做个盒保护一下。

既然要性能，那就配套设计一套超级轮毂吧。前轮单边配重158克，后轮100克，配重块用的是纯钨棒，密度19.3，和黄金差不多，轮毂47克。

整车重新装好，暂时用一代波箱（以后有空再设计一个更轻的），配2216外转子电机，am32电调，整车重4.8斤，轴距345，直立靠墙后轮离墙22mm，侧倾55度，正面爬理论最大坡度暂时没办法测，到了65度之后轮胎在砂纸上已经抓不住了，但是还没有抬头，重心已经够低了。总体效果还可以。

这也太硬核了，牛 好硬核 厉害了，大佬又有新动作https://app.rcfans.com/public/emotion/face_068.png 很强。 桥不错 可以量产造福模友了 别闹i 发表于 2022-11-15 22:41
桥不错 可以量产造福模友了
3D打印没有量产的说法，做1套和100套价格都一样，而且我这种冷门玩法没几个人玩的。 很棒https://app.rcfans.com/public/emotion/face_075.png
