Abstract

A forklift, a hydraulic cylinder assembly (100) and a hydraulic device thereof are provided. The hydraulic cylinder assembly (100) includes a cylinder (1) having first, second oil inlets (151, 152) and first, second oil outlets (153, 154) therein; a cylinder liner (2) disposed within the cylinder (1) and being moveable between first and second positions, and defining a first oil port (21) and a second oil port (22) therein; a piston (31) disposed within the cylinder liner (2) and being moveable between a third position and a fourth position; a first oil chamber (41) and a second oil chamber (42) are defined by the cylinder (1), the cylinder liner (2) and the piston (31), the first oil chamber (41) is normally communicated with the first oil port (21), and the second oil chamber (42) is normally communicated with the second oil port (22).

Description

technical field [0001] The invention relates to a hydraulic oil cylinder, a hydraulic device with the hydraulic oil cylinder, and a forklift with the hydraulic device. Background technique [0002] In modern machinery, there are often some linear reciprocating mechanisms, such as the feeding mechanism of the cutting sheet of the automatic cutting machine, and some automatic feeding devices. If mechanical transmission is used, complex structure or cumbersome electromechanical control is required, and there will be a large inertial impact when commutating, which will affect the life of the mechanism and form environmental noise. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. [0004] Therefore, an object of the present invention is to provide a hydraulic cylinder, which can be used to drive components for reciprocating linear motion, and has low operating noi...
