And if you want it to rock, why don't you just drop the center and forget about the suspension?

If you want to still have the suspension, you could either do what you suggested or make the suspension go up and down along an arc with radius equal to the distance between the front and middle wheels, so the chain has a constant distance.

How can I make the carriages pivot around the center axel?

There is currently no rock at rest. Once you begin moving the suspension absorbs any jarring movements like sudden stops or turns, making it handle more smoothly.
