The hydrostatic CVT is quite different from other CVTs, in that, it is not a frictional CVT system. Here, variable-displacement pumps are used to control the fluid flow to hydrostatic motors. In this system, a hydrostatic pump on the driving side is operated by the engine’s rotational motion. The rotational motion is then turned into fluid flow by the pump.

On the driven side, we have a hydrostatic motor that creates rotational motion by converting the fluid flow.

Hydrostatic transmissions, often, come with a set of planetary gears and clutches.  This results in a hybrid system referred to as a hydro-mechanical transmission. Such transmission systems allow power transfer from wheel to engine in 3 modes. First, there is the hydraulic transmission of power, which occurs at low speeds, then, we have the mechanical transmission of power, which occurs at high speeds,. In between high and low speeds, the system uses both, mechanical and hydraulic power transmission methods.

Hydro-mechanical transmission systems are used in heavy duty vehicles such as all-terrain vehicles and farm tractors.

On the whole, we have seen the various advantages of a CVT system over other transmission systems. They are more fuel efficient because of how they maintain optimum power range. They offer step-less acceleration, which eliminates the shift shock experienced in other transmission systems.
