Abstract
A fluid engaged spring released fan clutch having a modular mount usable with a spring engaged fluid released fan clutch is shown according to the teachings of the present invention. The modular unit includes a friction disc and a first outer shell section rotatably mounted thereto. The fluid engaged clutch portion includes a second shell section having an annular cylinder formed therein. A piston having a friction ring mounted thereon is reciprocably received on the annular cylinder and biased by spring means mounted between the piston and the modular mount. A rotary union is mounted on the second shell section for conduction of fluid pressure to cause the piston to move and engage with the friction disc. The spring engaged clutch portion includes a second shell section having a cylindrical plate held in a spaced relation therefrom. A piston having a friction ring mounted thereon is reciprocably received on the cylindrical plate and is biased by springs mounted between the piston and the second shell section. A rotary union is mounted on the second shell section for conducting fluid pressure to cause the piston to move and disengage with the friction disc. A series of fan blades are carried by the shell sections in the most preferred embodiments of the clutches of the present invention.
