Clutch System and Method
First Claim
1. A fan clutch device to be removably mounted to a drive member, the fan clutch device comprising:
- a hub portion that, when the fan clutch device is mounted to a drive member, is selectively movable relative to the drive member; and
a piston portion adjustable in an axial direction relative to the drive member when the fan clutch device is mounted to a drive member, the piston portion being adjustable between a first operative position and a second operative position;
a single spring device arranged between at least a portion of the hub portion and at least a portion of the piston portion to urge the piston portion toward one of the first position and the second position;
wherein the fan clutch device has a self-contained construction such that the hub portion, the piston portion, and the single spring device remain assembled to one another without a separate clamp device when the fan clutch device is separated from the drive member.

Abstract
A clutch system may include in certain embodiments a clutch body attached to a drive member such as a drive pulley, wherein the clutch body may be removed from the drive member without disassembling the clutch body. In various embodiments, the clutch body may include two clutch plates which enclose a spring-loaded pneumatic reciprocating assembly that in operation causes the plates to selectively separate and engage one another. In certain embodiments, the clutch body may be readily attached to a associated drive pulley in a single step by installation of a single set of fasteners.
