Title (EN) TRANSMISSION HOUSING, AND VEHICLE COMPRISING A HOUSING OF SAID TYPE
(FR) BOITIER DE TRANSMISSION ET ENGIN ROULANT EQUIPE D'UN TEL BOITIER
Abstract:
(EN) The invention relates to a transmission housing (1) comprising, at least partially accommodated in the housing (1): at least one conical friction clutch (2); a shaft (3) carrying said friction clutch (2); and a control device (4) for the friction clutch (2); the friction clutch (2) has at least one guiding female conical bearing surface (52) and at least one male cone (71; 72) which has a conical frictional surface and is mounted on the shaft (3) carrying the clutch (2) for conjoint rotation therewith; under the effect of the control device (4), each female conical bearing surface and the associated male cone (71; 72) can move from a disengaged position in which they are spaced apart, to an engaged position in which they are in supporting contact with each other; blocking means (81, 82) are arranged on the shaft (3), on both sides of the at least one mal cone (71, 72), at least one of said blocking means (81, 82) being made as a single part along with the carrying shaft (3).
(FR) L'invention concerne un boîtier (1) de transmission comprenant, logés au moins partiellement à l'intérieur du boîtier (1), au moins un embrayage (2) à friction à cônes, un arbre (3) porteur dudit embrayage (2) à friction et un dispositif (4) de commande dudit embrayage (2) à friction, ledit embrayage (2) à friction comprenant au moins une portée (51; 52) conique femelle dite menante et au moins un cône (71; 72) mâle à surface de friction conique monté solidaire en rotation de l'arbre (3) porteur de l'embrayage (2), chaque portée (51; 52) conique femelle et le cône (71; 72) mâle associé étant aptes, sous l'action du dispositif (4) de commande, à passer d'une position débrayée dans laquelle ils sont écartés l'un de l'autre à une position embrayée, dans laquelle ils sont rapprochés en contact d'appui l'un contre l'autre, des moyens (81, 82) d'arrêt étant disposés sur ledit arbre (3), de part et d'autre du ou des cônes (71, 72) mâles, au moins l'un des moyens (81, 82) d'arrêt étant réalisé d'une seule pièce avec ledit arbre (3) porteur.
