Abstract

Dans les boîtes de vitesses, pour changer de vitesses des arbres sont accouplés à des roues libres de manière sélective par l'intermédiaire de moyens d'accouplement. Les moyens d'accouplement comprennent généralement un corps qui est relié solidairement en rotation à l'arbre. Pour effectuer l'accouplement, les moyens d'accouplement comprennent habituellement un manchon coulissant qui comporte une denture axiale intérieure. Le manchon coulissant est relié solidairement en rotation, mais à coulissement axial, au corps. Le manchon coulissant est déplacé, par coulissement axial, sur une partie d'accouplement de la roue libre de sorte que la roue libre et le corps sont reliés solidairement en rotation par le manchon coulissant. Le but de l'invention est de proposer un dispositif d'actionnement, destiné à commuter une boîte de vitesses, qui est simple à intégrer. Pour cela, il est proposé un dispositif d'actionnement (1), destiné à une boîte de vitesses (2), qui comprend un insert de manchon coulissant (3) destiné à accoupler un corps de synchronisation (23), pourvu d'une roue libre (22a, b), à un moteur électrique (5) pour faire coulisser axialement l'insert de manchon de commutation (3). L'insert de manchon de commutation (3) est disposé coaxialement au moteur électrique et/ou dans le moteur électrique (5).
