Abstract

Dispositif permettant de changer immédiatement une roue libre de vélo sans outillage particulier. Il se compose : - D'une roue libre 3 se montant sur un moyeu 1 à l'aide de rampes inclinées 2, et d'ergots inclinés 4. - D'un roulement 5 centrant la roue libre 3 sur un axe de moyeu épaulé 8. L'ensemble maintenu en position par l'entretoise 6 et l'écrou 7. L'invention permet un remplacement de roue libre immédiat sans outillage, et une standardisation moins astreignante que les divers filetages existants.Device for immediately changing a bicycle freewheel without special tools. It is made up of: - A freewheel 3 mounted on a hub 1 using inclined ramps 2, and inclined lugs 4. - A bearing 5 centering the freewheel 3 on a stepped hub axle 8.
