The main types of gear mechanical transmission, electrical transmission and fluid power. Hydraulic transmission and hydraulic transmission fluid as the working medium is a fluid transmission, which is based on the hydraulic fluid pressure to drive to work, the hydraulic transmission in all areas of industrial production has a very wide range of applications, especially in combination machine Transmission is a unique advantage. The design of the machines hydraulic system, the use of all aspects of hydraulic system only through the work of the hydraulic system of loops and conditions to calculate the parameters, select the system circuit, components, accessories and so on. In meeting its requirements under the premise of using the system light weight, small size, performance, sound, and easy maintenance. In addition to the pressure to drive the pressure, the kinetic energy of the liquid depends mainly on work carried out. Key words: Hydraulic transmission, hydraulic pump 4
