About this creation


Using a 3 speed transmission there i saw in moc pages, i create this compact 5 speed transmission...
ask if you have any question.

Wow thats something new. Finally a fresh idea. Love the design. The only thing I see missing is somekind of shifting lever. You should come and see my own design of a H type dogleg 5+R manual transmission at http://www.mocpages.com/moc.php/248854 I think I've made quite a breakthrough with my realistic leaning gearlever. Please visit my mocpage and also see my other creations. Once again great work!!!

Well, I've managed to build a 5+R gearbox using four axles. Size is 15 studs long, compared to you 10 length. Height and width the same, using the technic motor brackets (32333). Reverse is minus 0,6; gears vary from gear one (0,36) to five (2,77). All I miss now is aneutral between 1 and R, because it the gearbox often chokes on switching, grasping both R and 1 for a sec... Back to the drawing board, before building the automated switcher...

Quoting Sander van Kreijl Well, the gear switcher should work out fine, I'm sure. I hope to find time to tinker on the switcher this summer. Switcher will consist off: PF M connected to a worm. Worm to white slip gear. Slip gear to 4 length arm. Arm to other arm that shifts the gear box. With your adjustments another two arms will be part or this... As mentioned in my previous mail, it will be more tough to get a compact true 5+R gearbox with all gears connecting just fine. My current 5+r gearbox varries from gear ratios 3:1 up to 1:3, which gives a good spread in performance. As mentioned before my current design is just too large (over 30 studs in length); your more compact approach should do the trick, using four axles instead of my current three (with only one sliding axle). But still: is your gearbox a true 5 speed, or 3 speed gearbox (see previous message)???
yes sure, a true 5 speed gearbox, but to carry gear shift i need to change 1 arm, tham i change the other arm, tham the other...speed 1 arm 1, speed 2 arm 2, speed 3 arm 1, speed 4 arm 2, speed 5 arm 1...understand? thanks

Quoting Sander van Kreijl Hi, It looks great. I've been working on a more compact RC gearox (compared to Sheepo's) but keep getting tot a too long gearbox for a 5+R config. Your config could work out great. A linear activator (of some sort) driving both levers, but with one retracted with a rubber band, should dot the trick. This will make one lever gear up, and the other one not until lever one has reached max gear and thus runs to a halt. When I calculate your gearbox I only come up with 3 different ratio's (0,6; 1 and 1,667), and thus effecively a three speed gearbox. Is this right? And can it be fixed in this compact model? Perhaps with a broader range of gear types?
hi dude, i was working in a system but i donīt have success, you can try to do...my project was simple, it uses axes to make the switch gear, look at the tyler reid audi R8 chassis, it is almost the same. in fact, I never tried to do it(hehe) but in theory it seemed complicated, so I did not try. but if you want, i can help you... thanks dude

That's genius! I wish I had thought to do that. That's the great thing about the online Lego community: we can build on each others' work. Have you worked out how to make it shift? It might be tricky to get those two axles to move at the same time using only one lever, although you could use two levers and sacrifice some realism. Also, you could lengthen it a couple studs and make it a 6-speed.

I would never have succeeded without your project, they realy help me to do that. To change gears, I'll do a single lever shifting from one axle to another, is dificult to explain, but when i do it, you will understand...thanks dude
