I know that there was a recent post with a working diff (sorry, differential), but I wasn't sure if the wheels (or fans) could spin at different speeds to each other, so I thought I'd give it a go...  I was using this as a basis - however I haven't figured out how to make the crown wheel yet - could do with a large gear... This is what I've got so far, however looking at the picture again, I've just thought of a way I might be able to improve it, so I'll be off to have another tinker... I haven't been able to figure out how to make the large wheels yet, I need to have a chat with the guy that managed to make it so you can rotate objects at angles other than 90 degrees...  Believe it or not, it does work, just remember to slow down the speed of the game so you can see it better, one wheel is set to about 0.2x full power and the other is set to 2x full power Hope this isn't a copy of somebody elses work (since I've just spent around 2 hours on it, somehow :S) and I hope somebody finds it helpful, even if it is just a starting point  Attachments:Diff Idea.bsg (16.83 KB)

I was hoping for a way to get this to work, since it would allow for many new designs. Unfortunately since all the gears are free-spinning, and there's no way to lock them in place on what they're mounted on...then it's impossible to make a working drive-shaft that continues sharing spin through the gear-assembly to the other side.
If you find a way though, I'll definitely be interested.

Wow, was so excited I almost shut Besieged without saving it xD Not sure if its counted as cheating or not, but I had to use Zeblote's mod so I could place objects at angles other than 90 degrees, and used various building methods others have shown on here Theres two attachments, idea 2 is the same as the photo - and you can see that each wheel will spin at seperate speeds. One thing that I need to point out though, after testing (see version 2 Half) is that each 'fixed' cog needs a strut going through it to the centre of the wheel to prevent them spinning individually... Or, try locking one cog, it might work, I haven't tested it... Idea 2 Half I have (tried) to put the unit into a holder, and then add a powered cog to show that it will all spin, however, after adding a <ahem> phew <ahem> stuts, it no longer runs very nicely on my computer, so I can't test it properly :S Perhaps somebody can make better use of struts... Or have a more powerfull computer.... But yeah, appears to be possible! With mods.... |

Well yea, when I said "not possible" I meant with the default game. But cool, nonetheless. Good luck fitting THAT under a vehicle!

True, its not in the default game yet, but you never know, the makers might also think that being able to put stuff at more than just 4 different angles could be very useful! |

If you find a way though, I'll definitely be interested. I guess it all depends on what you want in your differential. If you just want synched side shafts use this: besiege.freeforums.net/thread/881/mechanical-partsA real differential takes 100% of the input shaft power and outputs it all to the side shafts. Handy for cars turning since one wheel has to turn faster and go farther than the other. With a straight solution as shown above it wears out your tires and makes turning difficult, the vehicle crabs a bit. So here is a real differential with the bonus locking feature. Use forward/back to operate the one drive wheel (input shaft). Use the up and down to lock either output shaft to see how 100% is still transferred to the free shaft, it rotates at twice the input speed. The problem with a car is that when one wheel is on ice it just spins and does not transfer power to the other wheel which is on pavement. The offroad solution is the locking differential. For a bonus use the M/N keys to lock/unlock the diff (take it easy and watch, you can break the lock). Rock Crawler Heaven, try to brake the wheels now. This is meant for proof of concept so I left it all open and weak so you could see what was going on with the minimum parts. Praesumo, here is the thread that held the key for me: besiege.freeforums.net/thread/799/speed-manual-gearbox-proof-concept Attachments:Diff.bsg (6.11 KB)

Beefed up and cranked to max input speed (2)

Beefed up and cranked to max input speed (2) Why do they go at different speeds? It's really neat, but that makes it hard to use. |

Why do they go at different speeds? It's really neat, but that makes it hard to use. The idea is that power would go into the unit, then out through to the two wheels (or gears, w/e). The problem is when a vehicle with 4 wheels turns, the inside wheels will turn at a different speed to the outside. That's the reason why most (if not all) cars have a differential. Personally, I'm hoping it's possible to make it smaller so we can actually use it (easily) Or we could just stick to using 4 powered wheels that will turn at their own speeds - sounds easier... EDIT: Think you might have known that, just watched the video again, and the awnser is I have no idea XD Would have thought they would spin at the same speed, seeing as theres no resistance difference between the two - I did notice the gears giggling around a bit, maybe the gears kept loosing contact with each other so each side was spinning at a different speed? |

Even if everything is the same the outcome is different each time you run it. Until we have a gear with a different number of teeth the ratio will not be accurately controllable, it will vary based on randomness and whatever load/friction the game decides is there. |

With the version of this on the mount, I couldn't help but enhance it a little bit...
Made it a little faster. Added four powered wheels before the cog, turned their
speed all the way to max as with the cog. Now it's so fast if you run it on 1:1
time scale, it lags pretty hardcore but it's super fast.

The variation over time isn't the problem, it's that one is consistently faster than the other. It's more like bias in the physics. |

Is this what you guys are lookings for? Almost 100% accurate, functioning, and it is created from the same picture as the one from the top of this post. Hope this helps tinypic.com/r/344zktf/8 |
