Abstract: A power-split hydro-mechanical hybrid transmission system with an automatic adjustment function includes an input member, a hydraulic transmission mechanism, a split mechanism, a convergence mechanism, an output member, a clutch assembly, and a brake assembly. The clutch assembly connects the input member to an input end of the split mechanism, connects an output end of the split mechanism to an input end of the hydraulic transmission mechanism and an input end of the convergence mechanism, and connects an output end of the hydraulic transmission mechanism to the output member. An output end of the convergence mechanism is connected to the output member. The clutch assembly and the brake assembly provide a continuous transmission ratio between the input member and the output member. The power-split hydro-mechanical hybrid transmission system enables multi-mode continuously variable transmission and has energy reuse and emergency support functions.

Abstract: A brake-shift integrated system for wire-controlled vehicles based on machine-hydraulic compound and a control method thereof are provided. The brake-shift integrated system includes a shift module, a brake-by-wire module, a power distribution module and a control assembly module. The shift module includes a shift booster sub-module and a shift actuator sub-module. The shift booster sub-module is used to store and reuse the braking force to assist the shift. The shift actuator sub-module is used to implement mechanical automatic gearshift. The brake-by-wire module is used to implement the brake-by-wire process. The power distribution module is used for motor torque distribution. The control assembly module reads the shift signal, brake signal and current signal from each motor controller to control the operation of the shift motor and brake motor, the locking and releasing of the brake and the opening and closing of the solenoid valve.

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.
