    Abstract: A hybrid transmission device with a mechanical continuously variable transmission and a control method thereof are provided. The device includes an input shaft assembly, a front planetary gear transmission assembly, a rear planetary gear transmission assembly, an output shaft, and a mechanical continuously variable transmission. Single transmission modes and hybrid transmission modes are implemented through combination and engagement/disengagement of brakes and clutches. The device and the method realize free switching among various transmission modes and integrates the single transmission modes and the hybrid transmission modes, thereby increasing the degree of freedom in adjustment and expanding the speed regulation range. Input and output shafts of a front cup wheel and ring disc transmission mechanism and a rear cup wheel and ring disc transmission mechanism are coaxial, so that the structure is compact and intermediate rollers can stably and reliably transmit large torque.

    Abstract: A method for constructing an active magnetic bearing controller based on a look-up table method includes: building finite element models of an active magnetic bearing to obtain two universal Kriging prediction models in X-axis and Y-axis directions about actual suspension forces being in association with actual displacement eccentricities and actual control currents in the X-axis and Y-axis directions of the active magnetic bearing based on a universal Kriging model; creating two model state tables in the X-axis and Y-axis directions about the actual suspension forces being in association with the actual displacement eccentricities and the actual control currents to construct two look-up table modules with the two built-in model state tables, respectively; and constructing an active magnetic bearing controller by using two fuzzy adaptive PID controllers, two amplifier modules in the X-axis and Y-axis directions, the two look-up table modules, and two measurement modules in the X-axis and Y-axis directions.

    Abstract: A hydro-mechanical series and parallel transmission device and a control method thereof are provided. The device includes an input shaft assembly, a hydraulic transmission assembly, a planetary gear transmission assembly, an intermediate gear transmission assembly, and an output shaft assembly. Switching among a hydraulic transmission mode, a mechanical transmission mode, and a hydro-mechanical composite transmission mode is implemented through combination and engagement/disengagement of clutches and brakes. The hydro-mechanical series transmission is used to expand the speed regulation range of the hydraulic transmission and is combined with the hydraulic transmission to meet the requirements on precision and the speed regulation range. The requirements of low-power and high-power operations are met through combination of the hydro-mechanical series and parallel transmissions. Multiple transmission modes are formed to adapt to the working conditions of startup, operation, and transfer.

    IPC: F16H47/04

    Abstract: A hydro-mechanical transmission device with a dual-clutch transmission includes an input mechanism, a pump-controlled motor mechanism, an odd-numbered gear transmission mechanism, an even-numbered gear transmission mechanism, an output mechanism, and a jackshaft. The input mechanism is connected to the odd-numbered gear transmission mechanism and the even-numbered gear transmission mechanism that are connected in parallel, and is connected to an input end of the pump-controlled motor mechanism. An output end of the pump-controlled motor mechanism is connected, through the jackshaft, to the odd-numbered gear transmission mechanism and the even-numbered gear transmission mechanism that are connected in parallel, and is connected to the output mechanism. Switching among hydraulic transmission, hydro-mechanical transmission, and mechanical transmission modes between the input mechanism and the output mechanism is implemented by controlling combination and engagement/disengagement of clutches and a brake.
