Algodoo

Very good one!
Yoo just forget to set follow object.
I manage to brake it down (wheels on top of body) /-)

Kilinich write me "Very good one!", I´m so proud of myself
Thanks for responding
Can you help me? First gear is slipping because of HUGE torque (that is needed for climbing), how can i fix that?

The scene in its entirety is good, but the mechanical part is somewhat questionable. your way of making the engine simply gets the fun out of it, and probably behaves linearly, so it would be like an electric motor. And all of the gears slip. This is because you're running the scene at 60 Hz, and because the gearbox is composed of two smaller gearboxes. Use 120 and it may work better, but the thing that will really fix this is making it have only one contact point, i.e. only two gears.

Also, now that we have the negative adhesion concept, I guess you should try that. They run at like 5 or 6 times the speed than the engines we use right now, so they have like 5 or 6 times less torque too, which is perfect since you can add a 10:1 gearing made of C-gears or something like that on the output of the gearbox, and the gearbox itself would not slip.

And what was that about widgets??

- I don´t know if it is only for me but this scene runs at 50-70% speed at 60Hz so 120Hz sounds impossible
- Is that engine bad? I put it on my dyno with graph and it hade non-linear curve. I think that this type of spring engine need new name
- Is two-whelled gearbox better than multi-stage? Even if wheel will be huge? (i make this gearbox to fit that box, which have approx. real size)
- I´m using +inf friction and +inf adhesion to gearboxes (adhesion prevent wheels from detaching at high torque)
- I´m not good at making combustion engines, but i can give it a try

- About widgets, i will create a topic on algo.boards.net to discuss it, ok?

I think the scene ran ok, but still, your slipping problems come mainly from there

The engine is not bad, it's just too simple for an engine, and at the same time too overcomplicated for what it actually is. The point of making engines in Algodoo is to give the scene another challenge, otherwise you just drive a car through a 2d terrain thingy... for example I seemingly invented that type of engine with the springs that change length (my 5th scene I think [Don't look please]) but at least I used pistons.

And now that we have adhesion I have the theory that you can simply make a 5k RPM engine and hook it up to a low torque gearbox like the one I made, then add a fixed reduction at the output of the gearbox made of torque-withstanding gears like C-Gears. This way the gearbox is withstanding roughly 5 to 8 times less torque than before.
