Abstract: front page image
(EN)The present invention relates to a variable hydraulic motor for construction machinery and, more specifically, to a variable hydraulic motor, provided with a tilted device, for construction machinery, which allows easy processing, has reduced abrasion and enhanced durability, and shows a minimum speed deviation. To this end, the present invention provides a variable hydraulic motor for construction machinery, comprising: a casing; a rotational shaft rotatably installed in the casing; a cylinder block fixedly installed to the rotational shaft; a plurality of cylinders installed to the cylinder block along the circumferential direction of the rotational shaft; first pistons respectively slid into the plurality of cylinders; and a tilted device the front surface of which makes contact with the first pistons in a sliding manner, and the inclination of which is changed about a pivot coming in contact with the rear surface thereof, wherein the rear surface of the tilted device comprises a first inclination surface and a second inclination surface having mutually different inclination angles, wherein the rear surface of the tilted device further comprises a third inclination surface formed between the first inclination surface and the second inclination surface, and wherein the inclination of the tilted device is changed about the pivot coming in contact with an inclination change support point configured on the third inclination surface.
(FR)La présente invention concerne un moteur hydraulique variable pour machine de construction et, plus précisément, un moteur hydraulique variable, pourvu d'un dispositif incliné, destiné à une machine de construction, qui permet un traitement facile, présente une abrasion réduite et une durabilité améliorée, et présente un écart de vitesse minimal. À cet effet, la présente invention concerne un moteur hydraulique variable pour machine de construction, comprenant : un boîtier ; un arbre rotatif installé rotatif dans le boîtier ; un bloc-cylindres installé à demeure sur l'arbre rotatif ; une pluralité de cylindres installés sur le bloc-cylindres dans la direction circonférentielle de l'arbre rotatif ; des premiers pistons respectivement glissés dans la pluralité de cylindres ; et un dispositif incliné dont la surface avant vient en contact avec les premiers pistons d'une manière coulissante, et dont l'inclinaison est modifiée autour d'un pivot venant en contact avec sa surface arrière, la surface arrière du dispositif incliné comprenant une première surface d'inclinaison et une deuxième surface d'inclinaison ayant des angles d'inclinaison différents l'un de l'autre, la surface arrière du dispositif incliné comprenant en outre une troisième surface d'inclinaison formée entre la première surface d'inclinaison et la deuxième surface d'inclinaison, et l'inclinaison du dispositif incliné étant modifiée autour du pivot entrant en contact avec un point de support de changement d'inclinaison conçu sur la troisième surface d'inclinaison.
