Patent number: 8464680Abstract: 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 (26) intended to be coupled to the crankshaft, an outer ring (28) intended to be coupled to the ring gear, and at least one free wheel (30) provided with a plurality of wedging elements (34) mounted between raceways of the said rings. It further comprises means (50) designed to provide relative centering of the inner ring (26) and of the outer ring (28) and for transmitting radial load, the said means (50) being mounted at least partially between the inner ring and the outer ring leaving radial clearances between themselves and the said inner ring.Type: GrantFiled: October 14, 2008Date of Patent: June 18, 2013Assignee: Aktiebolaget SKFInventors: Jean-Philippe Gaborel, Pierre-Julien Barraud, Gwenaël Hingouet, Virginie Hamada

Patent number: 6568517Abstract: Ratchet free wheel device comprising a first element 1 provided with cavities 14, a number of ratchets 28 able to project into said cavities 14, and a second element 2 for supporting the ratchets 28 so that the second element 2 rotates as one with the first element 1 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 28 which is capable of preventing them from projecting into said cavities 14 so that the second element 2 is free to rotate with respect to the first element 1 in two opposite directions of relative rotation of said first and second elements when said control means is active.Type: GrantFiled: August 13, 2001Date of Patent: May 27, 2003Assignee: SKF FranceInventors: Marc Le-Calve, Christophe Houdayer, Virginie Hamada
