Re: Double the engines?

Everyone using tracks that are made from a chain that is not Roller Chain
have given up sprocket drive in favour of friction drive.
All normal chain drives expect the sprockets and the chain to remain in
alignment at all times , on a tank this does not happen when you are
trying to turn and so the chain rides up the sprocket and comes off ,
especially bike chain where the chain and sprockets are designed to do
that so the gears can be changed.
roller Chain is a different beast altogether.

Strangely the TTS friction drive may eventually be sprocket driven as it
is developed.

No, I've got a new idea on tracks myself.

Inspired by the motorcycles and marine engines I grew up around, I'm using a bike chain type track, but the chain is 2 links wide, so I can use a sproket and not worry about gaps in the tread. And since I'm using sprokets, tensing the track isn't a big deal. But I'm going to have to use a belt gear system. So that shouldn't be a problem, since it's not friction drive, should it?

Date: Wed, 22 Jan 2003 10:47:48 +0000 John Definitely breaking new ground here ! Personally I would power both ends of the track if you are going for the TTS friction drive , that way not all the power is being put into 1 set of wheels ? thereby increasing the friction area. regards paul At 04:50 27/07/2004, you wrote: >I was wondering if anyone could give me some advice on electric >motors.
