Title (EN) PISTON CYLINER AND FORKLIFT HAVING THE SAME
(FR) CYLINDRE DE PISTON ET CHARIOT ÉLÉVATEUR À FOURCHE DOTÉ DE CE DERNIER
Abstract:
(EN) A piston cylinder and a forklift having the same are provided. The piston cylinder includes: a cylinder body (1); a piston rod assembly (2) movable with respect to the cylinder body (1) and including: a piston rod (20); a first piston (21) disposed within and slidable with respect to the cylinder body (1), fitted over the piston rod (20) movably, and having a buffer groove (4) formed in an end surface thereof; and a second piston (22) located within the cylinder body (1) and fixed to the piston rod (20), and adapted to enter into the buffer groove (4) to be fitted therein and come out therefrom, and having a damping structure (221) to buffer the second piston (22) during entering of the second piston (22) into the buffer groove (4); and a stop member (3) disposed in the cylinder body (1) and configured to stop the first piston (21).
(FR) L'invention concerne un cylindre de piston et un chariot élévateur à fourche doté de ce dernier. Ce cylindre de piston comprend : un corps de cylindre (1); un ensemble tige de piston (2) mobile par rapport au corps de cylindre (1) et comprenant : une tige de piston (20); un premier piston (21) disposé à l'intérieur du corps de cylindre (1) et pouvant coulisser par rapport à ce dernier, monté de manière mobile sur la tige de piston (20) et présentant une rainure d'amortissement (4) ménagée dans une surface d'extrémité de celui-ci; et un deuxième piston (22) situé à l'intérieur du corps de cylindre (1) et fixé à la tige de piston (20), et conçu pour pénétrer dans la rainure d'amortissement (4) afin de pouvoir être placé à l'intérieur de celle-ci et de sortir de celle-ci, et présentant une structure d'amortissement (221) pour amortir le deuxième piston (22) pendant l'entrée du deuxième piston (22) dans la rainure d'amortissement (4); et un élément d'arrêt (3) disposé dans le corps de cylindre (1) et conçu pour arrêter le premier piston (21).
