In the sequential gearbox where the clutch is not used to dis/engage
to shift gears, but each gear is applied by applying a cone clutch to
bring it into mesh, what force keeps the pressure on the cone clutch ?
Springs ?

How big can this mechanism be scaled before you have to use outside
power hydraulic/air ?

Which vehicles use this gearbox ?

Are there any limitations to flowing a lot of torque through it ?

TIA
