摘要： A clutch mechanism intended to be installed between an engine and a transmission of a motor vehicle. The clutch mechanism is configured to be installed on the transmission (400) in two steps and by means of an axial locking system for axial locking of the control system (300) with respect to a clutch (100, 200). The axial locking system comprises a first axial locking element (304, 402) for implementing at least an axial retention between the control system (300) and the transmission (400), and a second axial locking element (600) for implementing at least an axial retention between the clutch (100, 200) and a shaft (A1, A2) of the transmission, and a means for rotational coupling of a clutch support (500) with respect to the control system (300), the rotational coupling means being different from the axial locking system.

摘要： A device for damping torsional oscillations comprises a support rotatable around an axis. At least one pendulum body is movable with respect to the support. At least one bearing member interacts with at least one raceway integral with the support and with at least one raceway integral with the pendulum body. The bearing member rolls along each raceway around an inactive raceway position. The first region is shaped to filter a first order value of the torsional oscillations by the pendulum body when the bearing member rolls along that first region. Two second regions are beyond an end of the first region. Each second region is shaped to filter a second order value of the torsional oscillations by the pendulum body when the bearing member rolls along one of those second regions. The second order value is strictly lower than the first order value.

摘要： A hydrokinetic torque-coupling device features a casing rotatable about a rotational axis and having an engagement surface, a torque converter including an impeller wheel and a turbine wheel, a locking piston including a piston body and a damper assembly. The piston body has a front surface axially facing the engagement surface of the casing. The locking piston is axially moveable along the rotational axis to and from the engagement surface of the casing to selectively engage the locking piston against the engagement surface of the casing in a lock-up mode. The damper assembly comprises an input member rotatable about the rotational axis and non-moveably attached to the turbine wheel, circumferentially acting elastic members and an output member elastically coupled to the input member trough the elastic members. The locking piston is non-rotatably connected to and axially moveable relative to the input member of the torsional vibration damper.

摘要： A hydrokinetic torque converter including a secondary piston for purposes of enhancing operation of the lock-up feature, and the method of operating such a converter. The secondary piston moves axially behind the turbine-piston to urge respective lock-up clutch friction surfaces into phased engagement. In an initial phase of engagement, friction surfaces between the secondary piston and turbine-piston engage to begin the reduction of relative rotary motion between the converter impeller and turbine-piston. This initial phase of slowing relative movement between the impeller and turbine-piston reduces pressure within the torus and the associated fluid forces separating the friction surfaces of the lock-up clutch. The secondary piston also slows and eliminates fluid flow from within the torus past the lock-up clutch and further reduces engagement resistance of the lock-up clutch owing to the lessening fluid pressure and flow. A more consistent lock-up clutch engagement, with higher torque capacity, is provided in both driven and coasting lock-up operation.

摘要： A pendulum-type torsional damping device comprises oscillating masses (6, 8, 10) mounted movably on a support (4). Each oscillating mass (6) is intercalated circumferentially between a first adjacent oscillating mass (8) and a second adjacent oscillating mass (10). Each oscillating mass (6) is mounted movably on the support (4) by a rolling contact via a single bearing element (12) associated with that oscillating mass, and a sliding contact between one of terminal edges (18) thereof and a terminal edge (20) of the second adjacent oscillating mass (10), which forms a radial retention edge for that oscillating mass (6). The device allows effective pendulum damping to be obtained with a limited number of bearing elements.
