    Abstract: 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 is usable with both hydraulic and pneumatic pressure actuation. Seal configurations create differently sized internal piston surface areas against which inlet pressure applied at hydraulic or pneumatic fluid inlet ports act to move the piston. The utilization of differently sized piston surface areas allows the piston to apply essentially the same clutch engaging compression force in both high pressure hydraulic actuation and lower pressure pneumatic actuation applications.

    Abstract: 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.

    Abstract: A clutch plate for a clutch assembly is provided. The clutch plate includes a body defining an outer circumference. A plurality of extensions projects radially from the outer circumference of the body. A first separating member is formed by bending a portion of at least one of the plurality of extensions along a first direction. The first separating member is configured to resiliently separate the clutch plate from an adjoining clutch plate of the clutch assembly along the first direction in a disengaged condition of the clutch assembly. A second separating member is formed by bending a portion of at least another of the plurality of extensions along a second direction. The second separating member is configured to resiliently separate the clutch plate from another adjoining clutch plate of the clutch assembly along the second direction in the disengaged condition of the clutch assembly.

    Abstract: A wet clutch comprising at least one friction disk (10) which is loaded by a piston (5) against an end disk (4). In order to run a forced pressure medium flow over the friction surfaces (11, 12) of the wet clutch, two pressures cavities (7, 8) having a connection in the region of the friction surfaces, are loaded with varying pressures. In order to improve such arrangements, the invention proposes that the leakage flow flowing over the supports of the friction disks is limited.
