爆改海博星小攀爬,打造最强小比例轴爬~

入模这么多年,一直未对攀爬提起兴趣。不过感觉对性能攀爬还是比较有好感,这段时间疫情关了好几天在家,实在无聊。突然翻到四年前买的海博星小攀爬,期间还改过一次,但是烂尾了,突然有种想把它改好的冲动~
http://image.rcfans.com/pic/20220321/1647871490849929_930.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20

下图是它原厂未改动的状态,论性能在同类里面算是不错的,特别是四轮转向功能,很强大。爬爬书桌啥的挺有意思~
不过玩久了也就觉得没意思,毕竟原厂还是有很多缺点,比如:
1.底盘太低,中间突出的波箱座很是不爽
2.重心太高,电池在上面,容易翻车
3.电池不能更换。
期间想改过,但是没有好的方案,最终烂尾~

http://image.rcfans.com/pic/20220321/1647871822166827_972.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
这次改装成功,主要是有灵感,灵感就是它:
n20减速马达
它小巧不占空间,便宜,扭力足,选择性多,简直完美!
http://image.rcfans.com/pic/20220321/1647872390946160_538.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
但是要把它与这台小攀爬完美兼容,还是需要很强的动手能力以及各种工具,好在本人两者皆具备,哈哈!最终我确认了双动力总成轴驱动的方案
以下是本人为这台小攀爬设计的动力总成:
http://image.rcfans.com/pic/20220321/1647872629217108_506.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
本来设计是两个马达和接收机都直接从接收取电,这样走线会简洁,可是买的马达转速偏低,还是直接从电池取电。

原厂的动力和电池全部舍弃,八十多克的重量
http://image.rcfans.com/pic/20220321/1647873014879765_75.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
由于传动角度的增大,原厂传动轴也得更换。
原因:
1是原厂传动角度无法满足需求
2是太短了
淘宝买的金属传动,简直完美,唯一的缺点可能偏长要切掉一点
http://image.rcfans.com/pic/20220321/1647873078696815_738.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
波箱也改了,加了一颗轴承,使得伞齿输出轴更稳。

http://image.rcfans.com/pic/20220321/1647873311576132_8.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
http://image.rcfans.com/pic/20220321/1647873311866273_627.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
原厂遥控和主板肯定舍弃,所以原厂5线舵机改了标准3线
http://image.rcfans.com/pic/20220321/1647873437593510_971.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
这么小的车子,车架各处的顺滑非常重要,球头宁松勿紧,但是原厂的这款球头很紧,需要研磨。我有迷你魔和螺旋测微器,所以小case
http://image.rcfans.com/pic/20220321/1647873642885404_465.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
其他的话最麻烦最折腾的就是不断地拆装以寻求最合适的孔位了,要想尽办法解决各种干涉问题,这个是最折腾人的,我起码拆装了二十多遍~
http://image.rcfans.com/pic/20220321/1647873857637586_462.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
然后就是布线,布线是最后进行的,只有确定好布局后,才能布好线。测试布局的时候电设的布局就先放一边吧,但也要考虑到方便布线
http://image.rcfans.com/pic/20220321/1647874096367197_904.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
http://image.rcfans.com/pic/20220321/1647874142018346_867.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
然后再给大家看下结构吧,最底层是两个动力总成,上面依次是接收机和电池,电池在前。
http://image.rcfans.com/pic/20220321/1647874339964895_288.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
http://image.rcfans.com/pic/20220321/1647874339965599_106.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
http://image.rcfans.com/pic/20220321/1647874339966812_445.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20
然后再说一下功能和控制,我用的mt4的遥控,其实这个控非常好用,混控功能很强大,只不过很多人不懂英文不会用罢了,改装后车子拥有的功能:
1.四轮转向,我用lever旋钮的三个档分别选择正常转向模式,大角度转弯模式,蟹爬模式。设置sw2按键屏蔽/开启两个特殊转向功能,非常方便。
2.比例断传功能,可以设置前后轮不同转速,用Dial旋钮控制比例大小,每转动一格改变的比例也可以调节,百分之0就是前轮转后轮不转,百分百就是正常,我设置的是每转动一格变动百分之20。

最后再说下轮胎吧,轮胎的抓地力对于一辆攀爬车的性能非常之重要,但是原厂的胎实在是太垃圾了,又硬又没有抓地,不过我告诉大家一个窍门,用磨胎机或者砂纸打磨一下会有很大的提升。但是我的建议是直接换了。本来这车的轮胎几乎没啥选择,也就mini qlo的原厂胎是个完美的选择,但是这玩意儿可遇不可求价格也离谱。幸运的是这几年小比例攀爬的流行这个规格的胎的选择非常多,前几天淘宝买的这套胎,拿到手发现简直完美呀,又软又异常的抓地,可以说秒原厂胎几百条街,而且我买的这个还是60直径的,原厂是55,太完美了。不过可惜原厂轮毂不兼容得重新买轮毂,这不疫情困住了,快递也收不了,郁闷呀~

改完只后性能爆棚呀,秒原厂几百条街了,每天在家里怕怕沙发,不亦乐乎,可好玩了哈哈~等轮毂到了有空我会拍个视频大家看看~
