Abstract

The invention provides a lightweight high-strength carbon fiber composite hydrocylinder. The hydrocylinder comprises metal heads, a hydrocylinder piston, a metal liner formed by a hydrocylinder barrel, fixing parts, metal lantern rings and sealing rings, the metal liner is externally and integrally coated with a reinforcing layer formed by a carbon fiber composite, the metal lantern rings are sleeved outside the reinforcing layer which is formed by taking thermosetting resin as a matrix and carbon fiber as a reinforcement, and the thermosetting resin matrix accounts for 23-40% of the reinforcing layer by weight. Compared with all-metal hydrocylinders in the prior art, the lightweight high-strength carbon fiber composite hydrocylinder has the advantages that strength, rigidity and fatigue resistance of the hydrocylinder are all obviously improved under various working conditions, so that safety of the hydrocylinder is improved effectively, weight is reduced by 30-65%, and the objectives of mechanical pump truck weight reduction and complete truck cost reduction are achieved.

Description

technical field [0001] The invention relates to a lightweight and high-strength carbon fiber composite material hydraulic oil cylinder. Background technique [0002] The hydraulic cylinder is a very important part of the hydraulic machinery. It plays the role of an actuator in the entire hydraulic machinery. The hydraulic cylinder converts hydraulic energy into mechanical energy in the whole process. With the sustained, healthy and rapid development of the economy, the demand for construction machinery for infrastructure construction has increased significantly, and hydraulic cylinders are special components for various construction machinery, coal mining machinery, special vehicles and large machinery. This also puts forward strict requirements on the height of the arm span of construction machinery. However, the all-metal hydraulic cylinders in the prior art have the problems of heavy weight, unsatisfactory strength, rigidity and fatigue resistance. All-metal hydrauli...
