A torque transmission device includes a first element, a second element, and a third element which are able to rotate about an axis of rotation; a first spring which is arranged between the first element and the third element; a second spring which is arranged between the second element and the third element; a first supporting seat positioned at a first end of the first spring; and a second supporting seat positioned at a first end of the second spring. The third element includes a torque transfer element directly transferring torque between the first spring and the second spring.

Torque transmission device with springs in series and torque transmission system comprising such a device

A torsion damping device for a vehicle transmission line including a first rotating element, a second rotating element, a main damper, a third rotating element and an additional damper. When the angular displacement between the first and second rotating elements is greater than zero and less than said first threshold, the at least one main spring is compressed while the third rotating element is rotated by the first rotating element via the uncompressed additional spring, and when the angular displacement between the first and second rotating elements is greater than said first threshold, the at least one main spring is compressed and the at least one additional spring is compressed in parallel, the compression of the additional spring being accompanied by the relative rotation of the first rotating element and the third rotating element.

Torsion damping device with main damper and additional damper

A torsion damping device for a vehicle drivetrain includes: a first rotary element, a second rotary element, an elastic device, a friction device including an actuating washer mounted to rotate as one with a friction washer and including an actuating tab interposed circumferentially between a first end of a spring and the first rotary element so as to allow relative rotation between the actuating washer and the second rotary element when the first end of the spring is compressed by the first rotary element in the direction of a second end of the spring opposite to the first end.

Torsion damping device with activatable friction device

A device for damping torsional oscillations, including: a pendulum-type torsional oscillation damper, a supplementary torsional oscillation damper including an input element, an output element, wherein both are configured to rotate around one axis rotation, and at least one mechanical energy accumulator device disposed between the input and output elements, a torque limiter, including at least one friction coating fixed on a disk, configured to be displaced around the axis. The disk is connected to rotate with the input element of the supplementary torsional oscillation damper and the friction coating is fixed to the disk of the torque limiter by an adhesively bonded surface-to-surface joint.

Device for damping torsional oscillations

A powertrain mechanism in a vehicle having an internal combustion engine. The powertrain mechanism is provided for transmitting power from the engine to a gearbox. The mechanism includes at least one drive plate and at least one connection hub. The hub has an assembly section disposed in at least one assembly opening provided in the vicinity of the center of the drive plate. At least one protrusion upper section defines at an uppermost section of at least one protrusion provided mutually on an inner wall of the assembly opening and on an outer wall of the assembly section. At least one recess base defines at a lowermost section of at least one recess wherein the at least one protrusion is at least partially placed. The powertrain mechanism further includes at least one movement gap provided between the protrusion upper section and the recess base.
