Abstract

See full text

A clutch assembly includes a fluid-actuated piston that allows clutch usage in both high pressure and low pressure applications. The configuration of the clutch assembly allows the piston to be used with different seal arrangements. These different seal configurations create differently sized piston surface areas against which the inlet pressure will act to drive the piston. The ability to change the size of the affected piston surface areas allows for the piston to receive essentially the same driving force under both high pressure and low pressure applications. Thus, the clutch assembly enables use of high hydraulic pressure (e.g., 320 psi) in combination with a seal arrangement that creates a small piston-driving surface area, and also use of low pneumatic pressure (e.g., 120 psi) with a seal arrangement that creates a large piston-driving surface area.
