哪位大神能看图解释一下某普差速器原理吗？
<font size="4">如题，图片是从某宝上截下来的，由于老父亲电动四轮车有异响，想搞懂原理自己修复。</font><br>
<font size="4">但是我从网上的图片里看不出有跟汽车差速器一样的结构，它是怎么工作的呢？如何差速的呢？</font><br>

这个应该是滚珠差速器

感谢分析，我知道汽车的差速器是这个原理，但是从网上的图片来看看不到这样的结构，所以有疑问

应该就是这里面了，要不然没办法差速。

啥是滚珠差速器能否详细介绍一下？<br>

你百度查一下吧。应该有的

<font size="5">从下图来看（差速齿轮裸露出来了）应该就是你画圈的那图片里面了</font><br>

就是上图这个大齿轮里的四个小齿轮实现差速的，这东西原理很简单的，
