[CN 201710299713.6] Hydraulic-mechanical compound stepless transmission device
[CN 201710299713.6] Title of Hydraulic-Mechanical Compound Stepless Transmission Device: Application Number of Hydraulic-Mechanical Compound Stepless Transmission Device: CN 201710299713.6 Applicant: Beijing University of Technology Application Date: 2017-5-2 Patent Type: Application for Invention The present invention discloses a hydraulic-mechanical compound stepless transmission device, including: hydraulic speed regulation circuit, planetary dividing and merging mechanism, hydraulic-mechanical fixed-axis gear transmission mechanism and forward-backward mechanism. The transmission device uses a planetary dividing and merging mechanism to realize two or three hydraulic mechanical sections, which are respectively used for starting, low-speed operation (and high-speed walking); the reverse gear includes two hydraulic mechanical sections. The hydraulic machinery section I adopts the split speed and torque power split form, the hydraulic machinery section II adopts the split speed and power split form, and the hydraulic machinery section III adopts the split speed and power split form. There is no circulating power in each hydraulic machinery section. Compared with the hydraulic mechanical power shift gearbox, the transmission device can obtain higher transmission efficiency. In addition, only one clutch needs to be operated to switch between sections, which can realize smooth switching.
