Problems solved by technology

[0007] However, such plates are subjected to excessive stress when the torque to be transmitted is large and are therefore not suitable for transmitting large torques

Embodiment Construction

[0053] first reference Figure 1 to Figure 4 , Figure 1 to Figure 4 The overall operation of a torsional vibration damper with elastically deformable plates equipped with a double flywheel damper 1 is shown. The double flywheel shock absorber 1 comprises a primary inertia flywheel 2 intended to be fixed at the end of the crank of an internal combustion engine (not shown) and a secondary inertia flywheel 3 with the aid of ball bearings 4 is centered and guided on the primary flywheel 2 . The secondary flywheel 3 is intended to form a reaction disc of a clutch (not shown) connected to the input shaft of the gearbox. The primary inertia flywheel 2 and the secondary inertia flywheel 3 are intended to be mounted movable about an axis of rotation X and additionally movable relative to each other in rotation about said axis X.

[0054] The primary flywheel 2 comprises a radially inner hub 5 supporting the rolling bearing 4 , an annular portion 6 extending radially from the hub 5 ...

Abstract

The invention relates to a torsional damper for a torque-transmission device, which comprises: a first element (102) and a second element (103) which are rotatable; and a resiliently deformable blade (117a, 117b) rigidly connected to one of said first and second elements, a bearing element (121) supported by the other one of said first and second elements and arranged such as to engage with the blade such that, for an angular deflection between the first and second elements relative to an inoperative angular position, the bearing element exerts a bending force on the blade, jointly producing a reaction force capable of returning the first and second elements into said inoperative angular position, said damper being characterised in that the blade comprises an inner portion (132) and an outer portion (134) connected by a bent section (133), the inner portion being located radially between the outer portion and a rotation axis.

Description

technical field [0001] The invention relates to a torsional vibration damper intended to be equipped with a torque transmission device. More specifically, the invention relates to the field of transmissions for motor vehicles. Background technique [0002] In the field of transmissions of motor vehicles, it is known to equip torque transmission devices with torsional dampers which allow the absorption and damping of vibrations and rotational inhomogeneities (acyclismes) produced by internal combustion engines. [0003] The torsional vibration damper comprises an input element and an output element movable in rotation about a common axis of rotation, and elastic damping means for transmitting torque and damping rotational inhomogeneities between the input element and the output element vibration. [0004] Such torsional dampers are equipped in particular with double freewheel dampers (DVA: doubles volants amortisseurs) and / or clutch friction elements in the case of manual o...
