So the transmission utilizes A selection of gears -- from very low to significant -- to produce more practical use of the motor's torque as driving situations modify. The gears is usually engaged manually or automatically.

The on-off qualities of a typical ratchet means that lots of of those designs are certainly not constant in Procedure (i.e. technically not a CVT), but in follow, there are lots of similarities in Procedure, as well as a ratcheting CVT will be able to create a zero-output pace from any specified input velocity (as per an Infinitely Variable Transmission).
