[CN 202010101329.2] Hydraulic mechanical transmission device with dual clutch speed change and control method thereof
[CN 202010101329.2] A hydraulic mechanical transmission device with dual clutch transmission and its control method Title: A hydraulic mechanical transmission device with dual clutch transmission and its control method Application number: CN 202010101329.2 Applicant: Jiangsu University Application date: 2020-2-19 Patent type: Invention application The present invention discloses a hydraulic mechanical transmission device with dual clutch transmission and its control method, it comprises an input mechanism, a pump control motor mechanism, an odd-numbered gear transmission mechanism, an even-numbered gear transmission mechanism, an output mechanism and an intermediate shaft. The input mechanism is connected with the odd-numbered gear transmission mechanism and the even-numbered gear transmission mechanism connected in parallel with each other, and at the same time is connected with the pump control motor The input end of the mechanism is connected; the output end of the pump control motor mechanism is connected with the odd-numbered transmission mechanism and even-numbered transmission mechanism in parallel transmission mechanism through the intermediate shaft, at the same time, it is connected with the output mechanism; by controlling the combined switching of the clutch and brake, the transmission mode of hydraulic transmission, mechanical hydraulic transmission and mechanical transmission between the input mechanism and the output mechanism is realized. Beneficial effects: the present invention can meet the operating requirements of multiple working conditions and energy management goals; reduce the impact of vehicle shifting, realize multi-stage high-efficiency continuously variable transmission; improve the energy utilization rate of the transmission device; optimize the shift quality of the variable speed transmission system.
