易控DF-7几个缺点的优化:齿轮杀猪叫和轴效应
帮朋友针对几个主要问题进行优化:1.齿轮杀猪叫
2.轴效应
3.轮胎磨车壳内漆
4.电机过热
5.枯草,泥土收集器
6.布线优化
首先说主要的:齿轮杀猪叫,这台车原厂齿轮装配很好了,标准作业本纸张厚度,配1600kv电机。随后我推测是电机齿T数太少,大齿T数太高,导致加速的时候两个齿轮间隙不断撞击(说实话感觉1600kv配这个电机齿真的太小了,明显感觉油门轰不上去)。直接换个20T试试,装配的时候稍微少留间隙直接贴着装,问题解决
除此之外,如图20T已经很极限了,大概还有1mm余量。根据我的粗略测量,这台车电机齿最大可以装到21T或者22T左右

轴效应就很好解决了,由于使用nb4遥控器,内置陀螺仪接收机接口太少,直接加装一个便宜的外置陀螺仪

为了姿态接近真实,后避震调的比较软,导致轮胎磨车壳,直接铝箔纸胶带加固

这个电机发热量也很恐怖,然而原厂并没有配散热就离谱,这天气傻跑一会电机就烫了(70度左右)

对于跑一圈里面全是枯草的问题,我用铝箔胶带把前轮后面挡起来了,可以起到一定作用

最后做个布线优化,电压传感器安排上,电调再加个防尘网,枯草真的会卡进去一堆

你咋把接收机的线给剪了 周周周 发表于 2022-12-02 13:07
你咋把接收机的线给剪了
侧面穿出去了 陀螺仪只能被动的修正轴效应引起的方向跑偏
无法减少轴效应
建议改造下后轮蚂蚱腿 我换了15T 换算下来接近2000kv 13t的转速 跑起来声音好听多了 短卡都用这么多通道 电机的散热风扇要多大呀 【易控DF-7解决齿轮异响(杀猪叫)-哔哩哔哩】 <br /><iframe src="//player.bilibili.com/player.html?bvid=BV1RW4y1u7Xo" scrolling="no" border="0" frameborder="no" framespacing="0" allowfullscreen="true"> </iframe> 命令方块 发表于 2022-12-02 23:59

电机的散热风扇要多大呀
安装位置很小,不适合大风扇
