Patent number: 10670021Abstract: In an aspect, a clutched device is provided, and includes an input member, an output member, a one-way clutch that can operatively connect the input member to the output member, and a motor including a stator and a rotor. The rotor is connected for rotation with a portion of the one-way clutch. The stator is operable to apply a first magnetic driving force to cause movement of the portion of the one-way clutch in a first rotational direction to increase a force of engagement between the input and output members. The stator is operable to apply a second magnetic driving force to cause movement of the portion of the one-way clutch to disengage the input and output members from each other.Type: GrantFiled: January 12, 2015Date of Patent: June 2, 2020Assignee: Litens Automotive PartnershipInventors: Scott D. Parsons, Gary J. Spicer, Roman Tracz

Patent number: 9169904Abstract: In a first aspect, the invention is directed to a multi-speed drive for controlling the speed of a load that is driven from a crankshaft of an engine. The multi-speed drive permits the speed of the load to be adjusted based on one or more parameters, such as vehicle speed, engine RPM, battery charge level (e.g. when the load is an alternator), coolant temperature (e.g. when the load is a cooling fan), engine power demand from the vehicle driver, water level in which the vehicle is driving (e.g. when the load is a cooling fan whose blades could be damaged or could cause damage to other vehicle components if they impact water during use). The speeds provided by the multi-speed drive may include two or more non-zero rotational speeds, or two or more non-zero rotational speeds and a zero speed, or one non-zero rotational speed and a zero speed.Type: GrantFiled: April 11, 2012Date of Patent: October 27, 2015Assignee: LITENS AUTOMOTIVE PARTNERSHIPInventors: Garreth Graves, Robert J.

Publication number: 20150285312Abstract: In an aspect the invention is directed to an isolator comprising a shaft connector that is connectable with a shaft of a motive device, a first rotary drive member that is operatively engageable with at least one second rotary drive member, a first isolation spring and a second isolation spring. The first rotary drive member and the shaft connector are rotatable about an isolator axis. The motive device may be an engine (and thus the shaft may be a crankshaft), or a motor for assisting an engine, for example. Examples of motors for assisting engines include motor/generator units (MGU's) that can operate as a generator when driven to rotate mechanically, and can operate as a motor when driven to rotate electrically. The first isolation spring is positioned to transfer a torque from the first rotary drive member to the shaft connector. The second isolation spring is positioned to transfer a torque from the shaft connector to the first rotary drive member.Type: ApplicationFiled: October 15, 2013Publication date: October 8, 2015Applicant: LITENS AUTOMOTIVE PARTNERSHIPInventors: Warren J.
