The identify "hydrostatic CVT," which misuses the term "hydrostatic," differentiates this kind of transmission from just one that comes with a hydrodynamic torque multiplier ("torque converter") into its style.
You may hear this after you’re driving; rather than the engine creating an audible fall in revs involving up-alterations, a CVT gearbox has a tendency to provide a continual drone as the car hurries up.

A variant called the Integrated Hydrostatic Transaxle (IHT) makes use of an individual housing for equally hydraulic things and gear-cutting down things which is applied in some mini-tractors and trip-on garden mowers.
A constantly variable transmission (CVT) is actually a sort of automatic gearbox, and it operates in A lot exactly the same approach to a conventional automatic gearbox from behind the wheel.
