Ratcheting CVTs can transfer considerable torque due to the fact their static friction really raises relative to torque throughput, so slippage is not possible in appropriately designed units. Performance is normally superior simply because the majority of the dynamic friction is a result of incredibly slight transitional clutch speed modifications.
It’s a tiny bit like heading out in a ship with a little outboard motor, you rev the outboard and also the revs remain precisely the same when the boat gathers velocity.
