关于差速锁，我也考虑过。在网上看到过有人改成遥控的，但是没有披露内部构造。我推测是钢丝牵拉滑块的原理。这意味着需要在原厂差速器上增加一些部件并考虑与原厂桥蛋内部空间的匹配度。原厂用顶丝贯通半轴的锁定原理适合手动，却不适合用遥控实现。另外，我这次改造的目标车型包括M998之类的运输车，所以必须清空车斗，背着个电池盒实在不好看，所以电池进了车头机舱。加上为了还原悍马的扁平感，车壳降低了5毫米，所以车架上安排电设的空间就更局促，再增加两个锁差小舵机很难安排。如果用换挡舵机混合控制也行，也就是低速档时锁定差速。但是这次我不打算搞得太麻烦，最终我采取了自己的简易方法，就是把顶丝留在铜柱螺母里，然后安装在桥蛋壳上。要开关差速时只要插入长柄扳手拧几下就行了。如下图。这比揣着顶丝和工具，然后拔掉原厂的很紧的盖子再操作要方便多了。其实在实际使用中，一般不会频繁地切换。比如我一般只锁定前面或后面就可以了。前后全锁使得转向半径太大，锁后半径稍大，锁前几乎不影响半径。这是我自己的心得。但不管怎样，遥控差速锁总是最好的，以后我还会尝试。

补充一句，我的方法虽然简单实用，但是有一个最大的缺点，就是全凭手感。因为这个铜柱包裹着顶丝，也遮住了洞口，所以看不见半轴，要在空挡时慢慢转动找到半轴上的孔才能拧入拧出。熟悉的人没问题，刚上手有点难。

你确实细心和用心，向你学习
钳工八级
一些更新如下。以前降低了车壳，但总感觉还不到位，这次抬高了桥蛋及其框架约5毫米，悬挂和转向系统也相应调整，总算有了自己基本看得过去的扁平感。

一些内饰和细节改良也在进行中。

请教一下 楼主 我的恒冠悍马车 空转是怎么回事，挂档舵机工作正常，挂挡应该是成功的，就是空转。
