Abstract

La machine hydraulique (2) comprend :- un boîtier (4),- un arbre,- une came,- un bloc à cylindres et à pistons apte à coopérer avec la came, et- un frein (112),Le frein comprend :- un empilement de disques (20) reliés alternativement au boîtier et à l’arbre,- un ressort (22),- un poussoir (26) sollicité par le ressort pour mettre les disques en appui mutuel, et- une première paroi (132) et une deuxième paroi (134) interposées entre le ressort et les disques par référence à une direction axiale (X-X) de l’arbre et délimitant une chambre (24) avec le poussoir de sorte que, lorsqu’une pression de liquide dans la chambre dépasse un seuil prédéterminé, le poussoir se déplace à l’encontre du ressort.La première paroi (132) est interposée entre le ressort et la deuxième paroi par référence à la direction axiale et montée mobile par rapport au boîtier.La machine comprend une butée (38) limitant une course de la première paroi (132) en direction du ressort de sorte que la première paroi demeure distante du ressort.La machine est agencée de sorte que le poussoir (26) vient en appui contre la deuxième paroi (134) lorsque le poussoir se déplace à l’encontre du ressort. Figure pour l’abrégé : Fig . 2The hydraulic machine (2) comprises: - a housing (4), - a shaft, - a cam, - a cylinder and piston block able to cooperate with the cam, and - a brake (112), The brake comprises: - a stack of discs (20) connected alternately to the housing and to the shaft, - a spring (22), - a pusher (26) biased by the spring to put the discs in mutual support, and - a first wall (132 ) and a second wall (134) interposed between the spring and the discs with reference to an axial direction (XX) of the shaft and delimiting a chamber (24) with the plunger so that when a liquid pressure in the chamber exceeds a predetermined threshold, the pusher moves against the spring. The first wall (132) is interposed between the spring and the second wall with reference to the axial direction and mounted to move relative to the housing. The machine comprises a stopper (38) limiting a travel of the first wall (132) in the direction of the spring so that the first wall remains remote from the spring. The machine is arranged so that the pusher (26) bears against the second wall (134) when the pusher moves against the spring. Figure for the abstract: Fig. 2
