Custom Clutch Gear
1nxtmonster replied to nxtstep101's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Nice job, but it looks a little weak. I built a clutch that used pneumatics to variable adjust the resistence, it could hold up to a lot. -

I've been doing some more offroading with it, and I have reached a conclusion...The gear range is too great; there is no middle gear. I want to make a three speed transmission, but until I do I changed the ratios so that the low gear is the same (1:15), but the high gear is a slower 1:5 instead of the previous 1:3. It is still fast, but I think it will add to the overall performance. For example, during a trial truck race, there are few flat areas, lots of medium hills and obstacles, and lots of hardcore obstacles. The old high ratio could only handle the flat areas, but the new high ratio is still fast but can take the medium hills as well.

I try embedding it by copying embed code: (<object width="560" height="315"><param name="movie" value="http://www.youtube.com/watch?v=Gtcr8hznKBU?version=3&hl=en_US"></param><param'>http://www.youtube.com/watch?v=Gtcr8hznKBU?version=3&hl=en_US"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/watch?v=Gtcr8hznKBU?version=3&hl=en_US" type="application/x-shockwave-flash" width="560" height="315" allowscriptaccess="always" allowfullscreen="true"></embed></object>) And then once I do that i click the special BB code button, select HTML code and insert this code. It shows the video to me, then won't show it when i post it... it just disappears.

If you follow me on my youtube (http://www.youtube.c...ser/1nxtmonster) you might have seen my RC crawler project. It used 2 RC motors and was quite fast and well performing. You might have also seen my RC rally car videos, they were fast and nimble. However, I want to combine the best of both worlds in one trial buggy package. So after a lot of trial and error, i was able to incorporate a 2-speed transmission into a crawler with RC motors. The ratios are 15:1 (slow crawler) and 3:1 (fast buggy). It is shifted by a mini linear actuator via an m motor. I'll do some more testing, and as usual this most likely isn't the final version. Pictures:
