Description

Technical Field

[0001] The utility model relates to the technical field of rubber hoses, in particular to a rubber hose for hydraulic transmission. Background Art

[0002] Hydraulic transmission refers to a transmission method that uses liquid as the working medium for energy transmission and control. In liquid transmission, according to the different forms of energy transmission, it is divided into hydraulic transmission and hydraulic transmission. Hydraulic transmission is mainly a transmission method that uses liquid kinetic energy for energy conversion, such as hydraulic coupling and hydraulic torque converter. Hydraulic transmission is a transmission method that uses liquid pressure energy for energy conversion. The use of hydraulic transmission technology in machinery can simplify the structure of the machine, reduce the weight of the machine, reduce material consumption, reduce manufacturing costs, reduce labor intensity, and improve work efficiency and reliability.

[0003] The hoses currently connected to hydraulic transmission generally have the problem of unstable connection with the hydraulic pump during transmission, easy water leakage at the connection with the hydraulic pump, and the rubber hose falling off when the rubber hose is connected to the connection port.
