[CN 201611117954.6] Two-stage hydraulic-mechanical compound continuously variable transmission device Title: Two-stage hydraulic-mechanical compound continuously variable transmission device Application number: CN 201611117954.6 Applicant: Chongqing University Application date: 2016-12-7 Patent type: Invention application The present invention discloses a two-stage hydraulic-mechanical compound continuously variable transmission device, including a power input shaft, a power output shaft, and a variable speed transmission component for transmitting the power of the power output shaft to the power output shaft, the variable speed transmission assembly includes a hydraulic pump, a hydraulic motor, and two sets of planetary gear mechanisms. The speed of the work vehicle at different stages is adjusted according to requirements through the transmission device. The transmission enables the work vehicle to have high transmission efficiency, low fuel consumption, and displacement. At the same time, it also enables the work vehicle to realize the function of stepless speed regulation, reducing the impact during the vehicle shift, and improving the comfort of the vehicle.
