(Sorry for mistakes (I'm not from Britain / America)) I was thinking about LSD (Limited Slip Differential) in lego. Because all I saw yet were just differentials with locking mechanism that engages after few turns of axle. And only thing it was limitting was main function of differential. So I came out with this solution - I know it isn't great, but it is very simple and compact (actually you add one rubber band inside differential (under spider gear)). What that does ? - When axles want to spin at different speeds (while cornering) more power is required (so you lose some speed if you don't have powferful motor) but, if one wheel lose traction the other one gets more power (compared to open differential) and you can also set how much additional friction you wat (by adding different number of rubber bands inside). Here is one picture of it : https://imgur.com/a/JTjgdBn I just want to know what do you think about it, and if there is possibility to create a real LSD in lego.
Howdy folks. Like many of you I'm sure, I'm taking the time to do a bit of building in the time off between Christmas and New Year. I've come across this little design that I haven't seen before, and thought I'd share in case someone finds it useful. If you would normally be using one of those white 24-tooth clutch gears (that slip after a certain torque is reached) but the torque limit for that gear is too high, or you can't fit the spur gear easily in your drivetrain, you may find this construction useful: Now, I accept that in practice it could be trick to work this into a MOC - the gear can only be supported one one side (unless you put a pin-joiner on the end and extend the axle from that) and a stud away from the support at that. But these aren't insurmountable, and if it's all you have, then you'll make do! On the other hand, it's also useful if you want to _add_ friction to a drivetrain for whatever reason. An alternative to sticking a normal gear on a friction pin. Owen.
