How can I model a train gear in CATIA V5?

I would like to simulate a gear train mechanism with the DMU Kinematics module, but I don't know how. I can build a gear mechanism but only involving two gears. Is there a way to simulate something like gear-a moves gear-b that moves gear-c?
I've solved this problem using a cheap trick in the assembly module: each gear has an angle constaint, so using formulae you can (kind of) simulate the whole mechanism. Anyway, I am sure there are better ways to archieve this.

there you have gear joint in catia dmu kinematics. you can chose the ratio and leave the rest of the things on the software to work out.

You are right, Abhijeet, but the gear joint is just for two gears. What I am trying to do is to simulate something like this:

Send me the model and will do it for you.

Thanks, Nedim! Here you have a simple model that I personally don't know how to simulate with DMU Kinematics.I hope you be luckier than me.
