Title (EN) CONTROL PLATE OF A HYDRAULIC MACHINE
(FR) PLAQUE DE COMMANDE D'UNE MACHINE HYDRAULIQUE
Abstract: front page image
(EN)A control plate (1) of a hydraulic machine having a core (2) is disclosed, which at least on its upper side (O) lying in operation against a cylinder drum is covered with a layer of a friction-reducing plastics material (3) and which has at least two control openings. In a control plate of that kind, it is desirable to simplify manufacture, during which subsequent machining is effected after the plastics material has been moulded on. For that purpose, the plastics material (3) is joined to the core (2) by means of at least one connecting element (8) which, as a result of interlocking engagement with the plastics material (3) and/or the core (2), takes up tensile forces substantially at right angles to the upper side (O).
(FR)L'invention concerne une plaque de commande (1) d'une machine hydraulique présentant une âme (2) laquelle, au moins sur son côté supérieur (O), fonctionne contre un tambour à cylindre, est recouverte d'une couche d'une matière plastique (3) réduisant les frottements, et présente au moins deux ouvertures de commande. Dans une plaque de commande de ce type, il est souhaitable de simplifier la fabrication au cours de laquelle un usinage subséquent est effectué après le moulage de la matière plastique sur ladite plaque. Pour ce faire, la matière plastique (3) est unie à l'âme (2) au moyen d'au moins un élément de raccordement (8) lequel, du fait de la solidarisation avec la matière plastique (3) et/ou l'âme (2), absorbe les forces de traction s'exerçant orthogonalement au côté supérieur (O).
