There an equivalent toothed insert in the freehub. Then there's an insert which goes into each which has teeth on the outside and a series of ramped teeth on the inside face, like this:
They're pressed together under load by two light pressure springs. When you start freewheeling, the ramps on the inside face of the inserts overcomes the spring pressure and pushes the two inserts apart, decoupling the freehub from the hub body.

I’m a bit confused about how those work. Do they have an external ratchet mechanism (star ratchet?) between the freehub and those splines in the hub? Or is there some kind of splined coupler I’m missing?
