20080245637 | Drive Through Air Compressor With Cone Clutch - A drive through crankshaft assembly which selectively provides rotational power to a vehicle accessory while continuously providing rotational power to a second vehicle accessory. Rotational power is selectively provided using a cone clutch assembly that is modular. The cone clutch assembly provides power to the first vehicle accessory when it is in an engaged state. The first vehicle accessory is turned off by putting the cone clutch assembly into a disengaged state using a clutch control system. | 10-09-2008 |
20090133982 | Synchronising Ring For A Synchronising Apparatus, A Friction Lining Blank And Also A Method For The Manufacture Of A Synchronising Ring - The invention relates to a synchronising ring for a synchronising apparatus of a change speed transmission, including a synchronising ring body with a friction lining, the friction lining being provided in a pre-determinable width between a first axial boundary surface of the friction lining and a second axial boundary surface of the friction lining in the circumferential direction around an axial synchronising ring axis of the synchronising ring on the friction surface, in such a way that the friction lining extends conically at a pre-determinable friction angle α about the synchronising ring axis. In this arrangement a macrogeometric groove is provided in the friction lining for the taking up and/or for the transport of a fluid in such a way that a flow connection is created by the macrogeometric groove for the fluid between the first axial boundary surface and the second axial boundary surface. In accordance with the invention the friction lining is completely removed in the region of the macrogeometric groove. The invention further relates to a friction lining blank for the manufacture of a synchronising ring and to a method for the manufacture of a synchronising ring in accordance with the invention. | 05-28-2009 |
20090173592 | Conical disk pair assembly with integrated torque sensor - A conical disk assembly including a shaft carrying an axially movable disk and having a fixed disk rigidly connected to the shaft. A support ring having first ramp surfaces facing the axially movable disk is carried on the shaft, and a rotatable sensing piston having second ramp surfaces that face the first ramp surfaces is axially movable along the shaft. Rolling elements are positioned between the ramp surfaces, and when the ramp surfaces are rotated relative to each other, the rolling elements move the sensing piston axially along the shaft. A guide ring is rigidly operatively connected to the axially movable disk and includes guide surfaces associated with the ramp surfaces for radially supporting the rolling elements. The guide ring and the support ring are connected with each other in a non-rotatable and axially movable manner to facilitate assembly of the conical disk assembly | 07-09-2009 |
20090205922 | Synchronizer ring with a fiber-reinforced, organic friction lining, and method for the production thereof - In a synchronizer ring including a fiber-reinforced, organic friction lining adhesively bonded to a conical surface area thereof, the friction lining is cut out of a flat sheet of organic friction material in the form of a number of strips which are curved in accordance with the shape of a development of the conical surface area of the synchronizer ring, the curved strips having the same general curvature at their inner and outer edges, the inner and outer edges having shapes such that the inner and outer edges are translationally congruent that is the shapes of the edges of adjacent strips are identical and the strips can be accommodated in side-by side relationship on the flat sheet thereby reducing cutting efforts and material waste. | 08-20-2009 |
20100065394 | Torque Limiting Clutch Assembly - A friction clutch comprising a plurality of first clutch plates and a plurality of second clutch plates, wherein at least a portion of each of the first clutch plates is frusto-conical in shape and wherein at last a portion of each of the second clutch plates has a shape that conforms to the at least the portion of the first clutch plates. A method for forming a friction clutch is also provided. | 03-18-2010 |
20100200354 | TAPERED COUPLING STRUCTURE AND ROTATING MACHINE - There is provided a tapered coupling structure in which a tapered shaft can be coupled to and decoupled from a hub without the use of an O-ring. In a tapered coupling structure | 08-12-2010 |

20140014457 | PNEUMATIC CLUTCH WITH IMPROVED CAPACITY AND LONGEVITY - Pneumatic fan drive assembly with improved capacity, longevity and heat control. The output member is positioned radially internally of the output member. The friction mechanism has longer movement (moment) arms and torque. The friction engagement has an increased friction surface arm. A portion of the heat generated by the friction mechanism is evacuated to the atmosphere rather than being completely internalized in the assembly. The friction material for the friction lining alternatively can be formed of a plasma spray. | 01-16-2014 |
20140299436 | FAN CLUTCH APPARATUS AND METHODS - Some embodiments of a fan clutch system may drive an output member to rotate at a first speed when opposing friction clutch surfaces are engaged and to rotate at a second, slower speed when the friction clutch surfaces are shifted to a disengaged position. In particular embodiments, the multi-speed clutch system may employ an eddy current drive system that is arranged axially rearward of the friction clutch surfaces while the fan blade device is mounted in a position that is axially forward of the of the friction clutch surfaces. | 10-09-2014 |

20100051404 | Separable Clutch for a Motor Vehicle with Automatic Wear and Temperature Adjustment - A separable clutch for a motor vehicle has a clutch plate including a moveably mounted release unit for engaging and disengaging the clutch. The clutch plate is pressure-medium actuated and includes an actuating piston which acts on the release unit in order to engage and disengage the clutch, and a pressure chamber which can be pressurized, and relieved of pressure, by pressure medium and which is delimited at one side by at least one part of the actuating piston and at the other side by at least one part of a clamping piston. At least the actuating piston, the pressure chamber and the clamping piston are resiliently supported in a defined position against the release unit by spring force. The force exerted by the spring is smaller than a limit force required for actuating the release unit. On account of a pressure change, brought about by a clutch actuation, in the pressure chamber, the clamping piston actuates a clamping device such that the clamping piston is fixed before the actuating piston actuates the release unit. | 03-04-2010 |
20150047943 | SPIRAL SPLINES TAPERED WEIGHT CLUTCH - A cone clutch having a male cone driven by a shaft transferring torque from a power source to a female cone, the male cone moveable along spiral splines on the shaft from a first position disengaged from said female cone to a second position engaged with the female cone, a spring located on said shaft between said male and female cones forcing the male cone towards the first position, the male cone forced to move towards the second position by the action of the spiral splines during rotation of the shaft. | 02-19-2015 |
