    摘要: A fluid coupling assembly for driving a cooling fan from an engine comprising a housing (10) defining a fluid chamber (12) having a volume and a drive member rotatably supported in the fluid chamber (12) of the housing (10) for transmitting torque between the housing (10) and the drive member through the shearing action of fluid (14) in the chamber (12). In some embodiments the housing (10) is adapted to drive the fan with the drive member adapted for connection to the engine and in the other embodiments the housing (10) is driven by the engine and the drive member is adapted for connection to the fan. A displacement device means is disposed in the fluid chamber (12) for adjusting the volume of the said chamber (12) to vary the coverage of the drive member by the fluid (14) to vary the shearing action of the fluid (14) to adjust the torque transmitted between the drive member and the housing (10). The assembly is characterized by the displacement devices including a threaded male element (44, 144, 244, 344, 444) and a threaded female element (46, 146, 246, 346, 446) for adjusting the volume of the chamber (12) in response to rotation of the male element relative to the female element, and a motor for rotating the threaded male element (44, 144, 244, 344, 444). The assembly also includes a computer (54) for controlling the motor for rotating the threaded male element (44, 144, 244, 344, 444) in response to various operating conditions.

    摘要: An automotive cooling assembly including a radiator and a cooling fan for forcing air over the radiator. A multiple speed fan drive interconnects the cooling fan to an engine of a vehicle. The multiple speed fan drive includes a fan shaft for supporting the cooling fan and a drive shaft running parallel to the fan shaft. A number of pulleys having associated belts couple the fan shaft to the drive shaft. An engagement device allows the fan shaft to remain stationary while the drive shaft is rotating. The engagement device also selectively engages one of the belts and their respective associated pulleys into driving relationship for rotating the fan shaft in response to rotation of the drive shaft. The rotational speed of the cooling fan can be faster, slower or in sync with the rotational speed of the engine. The cooling fan can also remain stationary while the drive shaft of the engine is still rotating. Hence, the cooling fan effectively forces air over the radiator of the engine when necessary, irrespective of the rotational speed of the engine.
