FRICTION CONE COUPLING DEVICE FOR A GEARBOX WITH A LOWER RING CENTRED ON THE HUB

The invention relates to a device for coupling an idle sprocket (4) to the shaft (2) of a gearbox including at least one fixed hub (6) on said shaft, a sliding gear (11) of the bearing type capable of freely rotating on the hub (6), and coupling means (11, 12, 14, 16, 17) between the hub (6) and the...

More Information
Summary:The invention relates to a device for coupling an idle sprocket (4) to the shaft (2) of a gearbox including at least one fixed hub (6) on said shaft, a sliding gear (11) of the bearing type capable of freely rotating on the hub (6), and coupling means (11, 12, 14, 16, 17) between the hub (6) and the sprocket (4) capable of equalising the speeds of the shaft (2) and of the sprocket (4) by friction and of converting the rotational movement received from the hub into an axial force on the sprocket (4) so as to themselves transmit by friction the torque between the hub and the sprocket. The coupling means include a lower ring (17) carried by a hub (6) and rotated by the latter, with an elastic cylindrical centring ring (19) provided between the hub (6) and the lower ring (17). Dispositif de couplage d'un pignon fou (4) avec un arbre (2) de boîte de vitesses comportant au moins un moyeu fixe (6) sur ledit arbre, un baladeur (11) de type roulement libre en rotation sur le moyeu (6), et des moyens de couplage (11, 12, 14, 16, 17) entre le moyeu (6) et le pignon (4), propres à égaliser par frottement les vitesses de l'arbre (2) et du pignon (4) et à transformer le mouvement de rotation reçu du moyeu en poussée axiale sur le pignon (4) de façon à transmettre eux-mêmes par friction le couple entre le moyeu et le pignon. Les moyens de couplage comprennent un anneau inférieur (17) qui est porté par un moyeu (6) et entra*né en rotation par celui-ci, avec une bague cylindrique de centrage élastique (19) disposée entre le moyeu (6) et l'anneau inférieur (17).
