Patent number: 10570986Abstract: A vibration damping device for a motor vehicle, features a first movable element (13, 14) and a second movable element (15, 16) both rotatable around an axis X, at least one group of elastic members (25, 26) mounted between the first movable element and the second movable element and acting against rotation of the first movable element and second element with respect to one another, and a phasing member (32, 33) rotationally movable around the axis X. The first movable element (13, 14) and the second movable element (15, 16) are coaxial and capable of transmitting a torque. The phasing member (32, 33) includes a first portion (32) and a second portion (33), for arranging the elastic members of the at least one group in series so that the elastic members of each group deform in phase with one another.Type: GrantFiled: July 19, 2016Date of Patent: February 25, 2020Assignee: Valeo EmbrayagesInventors: Gilles Lebas, Emmanuel Commeine, Roel Verhoog, Ivan Dutier, Thibault LaForge, Michael Hennebelle

Patent number: 10533627Abstract: A damping device for damping vibrations of a motor vehicle transmission drivetrain. The damping device features a first element and a second element (2) rotationally movable around a rotation axis X, an elastic damping member having an elastic blade (13, 14) mounted rotationally integrally with the first element (3) and a rolling body movable with respect to the second element along a curvilinear trajectory over at least a predetermined angular sector (A). Movement of the rolling body along the curvilinear trajectory with respect to the second element is accompanied by a movement of the rolling body on the elastic blade, causing the elastic blade to flex.Type: GrantFiled: January 22, 2016Date of Patent: January 14, 2020Assignee: Valeo EmbrayagesInventors: Ivan Dutier, Jerome Boulet, Herve Maurel

Patent number: 8616356Abstract: A friction clutch device for coupling a first rear motor shaft to a second front forced shaft by allowing free relative axial displacement between the two shafts. The clutch device includes a double shock-absorbing steering wheel having a primary couple input assembly which is fixedly mounted axially to the motor shaft, a secondary couple output assembly which is rotatably connected to a reactive plate of the clutch device which is supported by the forced shaft. An elastic circumferential action member is arranged in a cavity that is peripheral to the primary assembly to rotatably connect the secondary assembly, with circumferential shock absorption, to the primary assembly. The secondary assembly is fixedly mounted axially relative to the reactive plate.Type: GrantFiled: March 18, 2009Date of Patent: December 31, 2013Assignee: Valeo EmbrayaesInventors: François Thibaut, Patrice Bertin, Daniel Fenioux, Patrice Merou, Ivan Dutier
