More Information
Summary:An engine coolant pump drive system for a vehicle having an engine, an engine coolant system, and at least one sensor for sensing at least one operational condition of the vehicle is disclosed. The pump drive system includes a magnetorheological fluid (MRF) clutch, and a coolant pump. The MRF clutch includes a torque input section coupled to a torque output section via a MRF, the torque input section being configured to receive a torque input from the engine. The coolant pump is configured for operable communication with the torque output section of the MRF clutch. In response to a signal from the at least one sensor, the MRF clutch is configured to provide a continuously variable torque transfer from the torque input section to the torque output section, thereby providing for variable coolant flow in the engine coolant system via the coolant pump capable of a continuously variable speed.
