Patent number: 11732774Abstract: In an aspect a device for a driven shaft is provided that receives an input torque that varies cyclically between a peak input torque and a low input torque at a peak input torque frequency, which includes a shaft adapter, a rotary drive member, at least one isolation member, a torsional vibration damping structure including an inertia member and a elastomeric damping member, and a supplemental damping structure. The supplemental damping structure applies a supplemental damping torque to resist relative movement between the rotary drive member and the inertia member in addition to damping provided by the elastomeric damping member. A sum of torques including the supplemental damping torque limits a maximum twist between a first end of the driven shaft and a second end of the driven shaft, to below a yield point of the driven shaft.Type: GrantFiled: September 10, 2019Date of Patent: August 22, 2023Assignee: LITENS AUTOMOTIVE PARTNERSHIPInventors: Sean Kieran, Ahmed Abdul Wadood Anwer, Geoffrey William Ryeland, Ron Farewell, Kyle Pugsley, Frank Verriet, Andrew Malcolm Boyes

Patent number: 10240664Abstract: In an aspect, a tensioner includes a pulley, a main piston chamber, a reservoir, and first and second fluid passageways connecting the main piston chamber and reservoir, a main piston that is movable in the main piston chamber, a check valve, a control valve, and a movable reservoir member. The check valve prevents flow in one direction through the second passageway and permits flow in an opposing direction through the second passageway. The control valve is movable between to provide a first flow resistance, or a second flow resistance. The movable reservoir member is movable based on the amount of fluid in the reservoir in such a way as to change the volume of the reservoir, such that the reservoir, the main piston chamber and the first and second passageways together are included in a fluid circuit that is substantially free of any compressible fluids.Type: GrantFiled: June 22, 2015Date of Patent: March 26, 2019Assignee: Litens Automotive PartnershipInventors: Geoffrey W.

Publication number: 20170306836Abstract: In an aspect, a system is provided for controlling tension in an endless drive member, and including an isolation device and a tensioning system. The isolation device is positioned on an accessory drive shaft and has a pulley and a biasing member to transfer force from the pulley to the accessory drive shaft. The isolation device pulley is engaged with the endless drive member, such that a first span of the endless drive member is on a first side of the isolation device pulley and a second span of the endless drive member is on a second side of the isolation device pulley. The tensioning system has a first tensioner pulley engaged with the first span and a second tensioner pulley engaged with the second span. The first and second tensioner pulleys are urged by first and second tensioner pulley biasing forces towards the first and second spans respectively.Type: ApplicationFiled: October 20, 2015Publication date: October 26, 2017Inventors: Boris Replete, Ron Farewell, Andrew M.

Patent number: 9447850Abstract: A tensioner for an engine accessory drive system includes a tensioner arm pivotally mounted for movement between a free arm position and a load stop position. The tensioner arm includes a pulley which engages a belt. A piston, disposed in a cylinder, is pivotally linked to the tensioner arm. A spring urges the tensioner arm towards the free arm position. A moveable load stop member, controlled by an actuator, projects into the cylinder. The load stop member abuts the piston to thereby arrest movement of the tensioner arm and define the load stop position. The actuator may drive the load stop member against the piston to move the tensioner arm towards the free arm position so as to increase belt tension.Type: GrantFiled: March 15, 2013Date of Patent: September 20, 2016Assignee: Litens Automotive PartnershipInventors: Ron Farewell, Zbyslaw Staniewicz, Andrew M.
