The cause of the hydraulic transmission in China began in the 20th century, 50 years, developed its own internal combustion vehicles and CA770 Red Flag limousine of hydraulic drive system, and then the coal industry, pump industry there have been examples of the application of hydraulic transmission. Hoisting and conveying machinery Beijing Tianjin Engineering Machinery Research Institute and the Institute of the Ministry of the original mechanical and hydraulic coupling of the torque converter industry technical focal point for the development of hydraulic transmission in China has made important contributions. After reform and opening up, the state introduced the hydraulic transmission technology. From then on, the hydraulic transmission technology in China has entered a phase of great development.
