Problems solved by technology
[0002] At present, in some mobile hydraulic equipment, such as automobiles, airplanes, ships, construction machinery and other hydraulic systems, it is hoped to reduce the weight as much as possible, which can reduce energy consumption, and the strength and rigidity of the hydraulic equipment must be ensured during the weight reduction. Traditional Hydraulic cylinders cannot meet such requirements, and hydraulic components made of high-strength alloy steel or carbon fiber materials are expensive, and the manufacturing process is complicated and difficult
It is necessary to meet the requirements of portability and ensure strength and rigidity, but also to ensure production costs, so the design of changing materials cannot be used to make hydraulic cylinders in general hydraulic systems

Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] Such as Figure 1-3 As shown, a lightweight hydraulic cylinder includes a cylinder barrel 3 with a cylinder bottom 11 and a cylinder head 5 connected at both ends, a piston assembly is arranged inside the cylinder barrel 3, and a hollow piston rod 4 is connected to the piston assembly. The cylinder 3 reduces the wall thickness to 4-20mm, and the cylinder 3 is equipped with a first heat dissipation assembly 14, which is a heat dissipation rib 1 assembled on the outer wall of the cylinder 3, and the heat dissipation There are at least four ribs 1, and a second heat dissipation assembly 13 is installed on the outside of the cylinder bottom 11, the second heat dissipation assembly 13 is a cross-shaped rib plate 2 12, and the piston assembly is an assembled piston assembly. The hydraulic cylinder reduces the weight of the cylinder 3 by reducing the...

Abstract
The invention relates to the technical field of hydraulic cylinders, in particular to a light-weight hydraulic cylinder. According to the technical scheme, the hydraulic cylinder is characterized by comprising a cylinder barrel with the two ends connected with a cylinder bottom and a cylinder cover, a piston assembly is arranged inside the cylinder barrel, a hollow piston rod is connected to the piston assembly, a first cooling assembly is assembled to the cylinder barrel, the cooling assembly comprises at least four cooling rib plates assembled on the outer wall of the cylinder barrel, a second cooling assembly is assembled at the outer side of the cylinder bottom, the second cooling assembly is a rib plate of the crossed structure, and the piston assembly is an assembled piston assembly.The hydraulic cylinder has the advantages of being low in weight, capable of achieving accelerated cooling, simple in manufacturing technology, low in cost and convenient to assemble and disassemble.
Description
technical field [0001] The invention belongs to the technical field of hydraulic cylinders, in particular to a lightweight hydraulic cylinder capable of accelerating heat dissipation. Background technique [0002] At present, in some mobile hydraulic equipment, such as automobiles, airplanes, ships, construction machinery and other hydraulic systems, it is hoped to reduce the weight as much as possible, which can reduce energy consumption, and the strength and rigidity of the hydraulic equipment must be ensured during the weight reduction. Traditional Hydraulic cylinders cannot meet such requirements, and hydraulic components made of high-strength alloy steel or carbon fiber materials are expensive, and the manufacturing process is complicated and difficult. It is necessary to meet the requirements of lightness and strength and rigidity, but also to ensure production costs, so the design of changing materials cannot be used to make hydraulic cylinders in general hydraulic sy...
