最终的选择-直驱yd2

今天终于把车子弄好了,下地跑过后也已经很满意,速度不慢,操控非常好(这是我最看重的,当然,如果换一个环境,大家都很快,那我也只能快)

直驱的虚位真的可以做到非常非常非常小
不管是舵机到轮子之间的
还是讲转向打到最大后两个轮子之间的

这个可能有点难讲清楚
把转向打到最大
我这台车可以动一点外侧轮子,内侧轮就能跟着动
换其他的转向组就可能不会有这个效果,最后一段两个轮子基本是失联的

当然,虚位等等都没有那么重要,相比较操控,平衡等更加关键
所以千万不要舍近求远

直驱的转向组阻力也是更小的,舵机可以更好的出力,车子反应也会更加清晰

总之用过就回不去了

另外,这套直驱也有非常丰富的可调性,各种地方拆装设计都很人性化,如果配合直驱镂空底板,那么每一处地方都可以有下螺丝刀的位置,另外还有舵机线的前后理线槽

调整caster有好几种方式,因为上摆臂固定座的空间是已经完全调整好并且留给上摆臂的距离是固定的,所以可以像yd2 传统的方式一样调节摆臂内2mm的垫片的前后位置,而不需要再调整虚位

亦或者更改成1+1mm,0.5+1.5mm等等,由于摆臂固定座内的间隙是经过0.1mm垫片调整好的,Pin也更改成了更高精度的针规pin

所以你只管换垫片,剩下的就只有拧螺丝,无需频繁调整虚位

第二种方式就是用垫片调整上摆臂固定座整体的前后位置

上摆臂固定座是有三段前后可调的,只需配合其与六角铝柱之间的两颗垫片厚度即可实现快速及大范围调整

当然,还有拓展的安装方式如调整摆臂正反,转换前面分体的油压架与上摆臂固定座在六角铝柱上的前后的位置等等

舵机臂与转向片的固定方式也采用了沉孔,拥有更好的安装精度,可以保持其与转向片始终居中

转向片有几种不同宽度,每一片都可以在你松开两颗沉头螺丝后前后滑动,来改变整体的长度

当然,舵机整体也是可以前后滑动的,快速的调整阿克曼,往前滑,阿克曼就小,往后滑,阿克曼就变大,超级简单

但是这次需要松开的是四颗螺丝了~

这四颗螺丝的滑动槽采用了高精度设计,只允许前后滑动,左右晃动被杜绝,四颗螺丝定位也保证了精度

最终的效果就是舵机左右epa可以完全一致

另外要讲到的就是droop steer,拉杆足够平,而且这套直驱转向片的宽度可以使得转向拉杆的长度是更接近于上下摆臂长度的甚至是更长的,这一点是传统转向组以及其他直驱没有的优势

最后是一部分安装照片

完全根据原车数据设计的上摆臂高度,固定宽度,以及油压架孔位,不会改变原车的优秀操控性能,可以说无损(原车数据)安装、也能够有更好的兼容性

舵机的安装高度也是数据化设计完成,转向拉杆有着近乎完全平行的角度

一切的一切都是那么的恰到好处

有朋友想问可不可以给其他车用?答案当然是可以的,那你要再问我有没有试过,我只能说能力有限,我只能先玩好我自己的,不过理论上是通用,并且有如此高可调性能的直驱,还担心啥呢?

最后看整车定妆照,完结

传动组件越少肯定虚位控的越好,你是真的钻研

直驱唯一的缺点就是,看起来不那么高端https://app.rcfans.com/public/emotion/face_wulian.png,但讲真,用过真就回不去了,我pds也是直驱,每次动转向数据,都好调的一匹,特别快,相爱比mst的雨刮转向组,调整好了就基本不想再动了,完全没有继续尝试新数据的欲望,毕竟螺丝拧多了,容易滑丝https://app.rcfans.com/public/emotion/face_048.png

学弟,无条件支持你,你是我们西工大的骄傲。你和我的zero理念一样,必须的epa对称,三杆等长。此举可改善车头起伏造成的阿克曼变化。
