Technical Examples

A variable fan drive for a vehicle powered by an internal combustion engine is provided. A drive side assembly utilizes a hydraulic actuator to actuate a variable sheave assembly. The variable sheave assembly drives a sheave assembly of a driven side assembly by way of a v-belt. The hydraulic actuator has a piston coupled to the variable sheave assembly. The piston is hydraulically translated by pressurized engine oil from the internal combustion engine. An electronically controlled solenoid valve controlled by an engine or vehicle controller selectively controls the flow of engine oil for piston actuation. Thus the speed of the fan can be controlled based on various engine or vehicle operating parameters.
