20080277230 | HYDRAULIC DRIVE SYSTEM WITH AGGRESSIVE CLUTCHING - A hydraulic drive system for storing and releasing hydraulic fluid includes a high pressure storage device, a low pressure storage device, and a pump-motor operating at a range of pump-motor speeds for converting between hydraulic energy and mechanical energy. The pump-motor is disposed between the high pressure device and the low pressure device. In normal operation, the hydraulic drive system enters a motoring mode where hydraulic energy is released from the high pressure storage device and converted to mechanical energy using the pump-motor. It also enters a pumping mode where mechanical energy is converted into hydraulic energy. A neutral state exists where hydraulic energy is neither stored nor released from the high pressure storage device. An approach for facilitating the application of a clutch when it is not a simple on/off mechanism provides an enhanced interface for the conversion between hydraulic energy and mechanical energy, thereby improving efficiency within the hydraulic drive system. | 11-13-2008 |
20090114497 | Inflatable Tube For Coupling Component And Method For Making An Inflatable Tube - An inflatable coupling component tube for a fluid-operated brake or clutch includes an elongated, generally tubular-shaped structure of predetermined length having two ends and a joint between the two ends that closes the tube to form a generally toroidal-shaped cavity. A coupling component for a fluid-operated brake or clutch that includes an inflatable tube, and a method of making an inflatable coupling component tube are also disclosed. | 05-07-2009 |

20150369306 | TWO SPEED CLUTCH WITH VISCOUS SYSTEM - A clutch device for a clutch system has an input member that rotates at a first speed. A friction drive system is disposed between the input member and an output member. The clutch device is selectively movable by a fluid actuator assembly, between an engaged position in which the friction drive system drives the output member to rotate at the first speed, and a disengaged position in which a viscous drive system rotates the output member at a second speed slower than the first speed. A variable viscous fluid supply assembly includes a viscous fluid storage chamber, a valve, and a valve actuator that selectively drives the valve to move between an open position and a closed position to control an amount of viscous fluid available to the viscous drive system, thereby varying the second speed. | 12-24-2015 |
