The disengageable module for a system for transmitting a starting torque to an internal combustion engine, of the type comprising a ring gear connected to the crankshaft of the combustion engine, comprises an inner ring () intended to be coupled to the crankshaft, an outer ring () intended to be coupled to the ring gear, and at least one free wheel () provided with a plurality of wedging elements () mounted between raceways of the said rings. It further comprises means () designed to provide relative centering of the inner ring () and of the outer ring () and for transmitting radial load, the said means () being mounted at least partially between the inner ring and the outer ring leaving radial clearances between themselves and the said inner ring.

The invention concerns a freewheel bearing device including an outer element and inner element arranged inside the outer element, and a free wheel provided with at least a wedging element, arranged between the inner element and the outer element to allow a free rotational movement in one direction between the outer element and the inner element and for transmission of a torque in the other direction between the outer element and the inner element, the free wheel including a ring provided with a cylindrical inner surface and a cylindrical outer surface, substantially aligned on a radial plane perpendicular to the axis of rotation of the device, and a torque limiting member adapted to limit the torque transmitted by the free wheel, the torque limiting member being arranged radially between said ring and the outer element or the inner element in contact with said ring and said element.

The disengageable pulley device includes a pulley mounted on an internal transmission element, and a free wheel provided with a plurality of wedges and with a cage for the wedges, said free wheel being designed to provide one-way engagement between the pulley and the internal transmission element. The device includes an elastic connecting member provided with a first fixing part for fixing it to the internal transmission element, with a second fixing part for fixing it to the cage, and with a working part between said fixing parts, said working part being radially moveable relative to the internal transmission element and being adapted to exert a circumferential return force on the cage.

Ratchet free wheel device comprising a first element provided with cavities a number of ratchets able to project into said cavities and a second element for supporting the ratchets so that the second element rotates as one with the first element in one direction of relative rotation of said first and second elements and is free to rotate in an opposite direction of relative rotation. The device comprises a means of controlling the ratchets which is capable of preventing them from projecting into said cavities so that the second element is free to rotate with respect to the first element in two opposite directions of relative rotation of said first and second elements when said control means is active.
