Theoretical Analysis Of Piston Hydraulic Torque Converter

Based on the structure of the double stator which has curves of constant width, this paper puts forword the basic concept of hydraulic torque converter. Because the converter consists of the inner piston pump and the outer double-acting double-stator motor, named the new torque converter as piston hydraulic torque converter. Different from the tratidional fluids torque converter, piston hydraulic torque converter is a totally new torque converter which is based on Hydraulic Power Transmission.To piston hydraulic torque converter, the oil coming from inner pump is served as source of the motor oil. The double-acting link-roller double-stator motor is consist of four normal motor. It is able to realize twelve speeds or torques according to different linking way. This is very important to some machine which needs many speeds.Piston hydraulic torque converter is a torque converter based on Hydraulic Power Transmission. It’s different from fluids power transmission. At the beginning, the paper gives a simple introduction of the research’s background and significance. Then it presents the classification 、 advantage and disadvantage of fluids power transmission. After the introduction of Piston hydraulic torque converter’s structure,the paper relates it’s advantage and applications. Disscussing the speed ratio、the stator curves of motor and volatility.AS the device suits to medium or low pressure system in particular, The paper gives a detailed analysis of kinematics 、dynamics and leakage.Piston hydraulic torque converter is a deep development of double stator and fluids power transmission to hydraulic power transmission of torque converter. It provides a new research direction of hydraulic components.
