20090298646 | ENGINE POWERED DEVICE HAVING ACCESSORY DRIVE AND REVERSING MOTOR FOR SELECTIVELY STARTING ENGINE AND POWERING ACCESSORY DRIVE - A device having an engine, a motor/generator and an accessory system having an accessory that is driven by rotary power. The device can be operated in a first mode in which the engine provides rotary power for driving the accessory and the motor/generator. The device can be operated in a second mode for starting the engine and driving the accessory in which rotary power is output from the motor/starter in a first rotational direction. The device can also be operated in a third mode in which the motor/generator outputs rotary power in a second, opposite rotational direction for driving the accessory while the engine is not operating. A method for operating the device is also provided. | 12-03-2009 |
20100122882 | DRIVEN ACCESSORY WITH LOW-POWER CLUTCH FOR ACTIVATING OR DE-ACTIVATING SAME - A driven accessory having a clutch that permits selective operation of an accessory portion. The clutch employs rotational inertia to control driving engagement of a wrap spring to an interior clutch surface on a drive member and/or driving disengagement of the wrap spring from the interior clutch surface. | 05-20-2010 |
20100230227 | DRIVEN ACCESSORY WITH LOW-POWER CLUTCH FOR ACTIVATING OR DE-ACTIVATING SAME - A driven accessory having a clutch that permits selective operation of an accessory portion. The clutch employs rotational inertia to control driving engagement of a wrap spring to an interior clutch surface on a drive member and/or driving disengagement of the wrap spring from the interior clutch surface. | 09-16-2010 |
20110053729 | Auto-Selecting Two-Ratio Transmission - A pulley assembly with an auto-selecting multi-speed transmission that can be operated in at least two modes depending on the manner in which rotary power is transmitted through the pulley assembly. | 03-03-2011 |
20110315502 | DECOUPLER FEATURING HELICAL WRAP CLUTCH SPRING AND COIL DAMPER SPRINGS - A decoupler having a hub, a drive member and an isolator. The drive member is disposed about the hub for rotation about a rotational axis and includes an inner clutch surface. The isolator couples the hub and the drive member and includes a carrier, a plurality of arcuate springs, and a wrap spring. The carrier is received between the hub and the drive member and includes a carrier member, which defines a pair of apertures, and a pair of reaction blocks that are mounted in the apertures. The arcuate springs are mounted in the carrier member and are disposed between the hub and an associated one of the reaction blocks. The wrap spring has an end and a plurality of helical coils that are engaged to the inner clutch surface of the drive member. The end has an end face that is abutted against one of the reaction blocks. | 12-29-2011 |
20120231928 | ENGINE POWERED DEVICE HAVING ACCESSORY DRIVE AND REVERSING MOTOR FOR SELECTIVELY STARTING ENGINE AND POWERING ACCESSORY DRIVE - A power transmitting system that is configured to have BAS and IS functionality. The power transmitting system can be operated in a first mode in which an engine provides rotary power for driving an accessory assembly and a motor/generator. The device can be operated in a second mode for starting the engine and driving the accessory in which rotary power is output from the motor/starter in a first rotational direction. The device can also be operated in a third mode in which the motor/generator outputs rotary power in a second, opposite rotational direction for driving the accessory while the engine is not operating. A kit for a power transmitting system is also provided. | 09-13-2012 |
20130008758 | DRIVEN ACCESSORY WITH LOW-POWER CLUTCH FOR ACTIVATING OR DE-ACTIVATING SAME - A driven accessory having a clutch that permits selective operation of an accessory portion. The clutch employs rotational inertia to control driving engagement of a wrap spring to an interior clutch surface on a drive member and/or driving disengagement of the wrap spring from the interior clutch surface. | 01-10-2013 |
20130093547 | ELECTRO-MECHANICAL DEVICE AND ASSOCIATED METHOD OF ASSEMBLY - A method of setting an air gap between an electromagnetic coil and an armature of an electro-mechanical device to be within a desired range includes applying a sensing signal to the electromagnetic coil and monitoring at least one electrical characteristic of the electromagnetic coil. The at least one electrical characteristic is related to a size of the air gap and the sensing signal. The method further includes moving the armature towards the electromagnetic coil to reduce the size of the air gap and stopping movement of the armature towards the electromagnetic coil when the at least one electrical characteristic indicates the size of the air gap is within the desired range. | 04-18-2013 |
20130187736 | ELECTROMAGNET AND ELECTROMAGNETIC COIL ASSEMBLY - An electromagnet may comprise a pole piece ( | 07-25-2013 |
20130313068 | DRIVEN COMPONENT WITH CLUTCH FOR SELECTIVE OPERATION OF COMPONENT - A component, such as an engine accessory for an automotive engine, that has clutch with a helical clutch coil and an axially movable armature. The helical clutch coil is normally engaged so as to transmit rotary power between a driving member and a driven member. The armature can be moved to apply a force to a tang of the helical clutch coil that causes the helical clutch coil to disengage to an extent where full rotary power is not passed through the clutch to drive the component. | 11-28-2013 |
