[CN 201711101124.9] Single-row compound planetary gear type multi-section hydro-mechanical continuously variable transmission
[CN 201711101124.9] A single-row compound planetary gear type multi-section hydro-mechanical continuously variable transmission Title: A single-row compound planetary gear type multi-section hydro-mechanical continuously variable transmission Application Number: CN 201711101124.9 Applicant: Shihezi University Application Date: 2017-11-10 Patent Type: Invention Application The current hydro-mechanical continuously variable transmission mostly adopts the form of multi-row planetary gears in series, but the transmission structure is complicated. The invention provides a simple structure, convenient processing and assembly, multi-section, high-efficiency hydraulic-mechanical continuously variable transmission. It is characterized in that the triple planetary gear 6 is composed of three gears and shares the planetary carrier rod 8. There are three sun gears meshing with the triple planetary gear 6, and then meshing with the inner ring gear 7 can form a single row Compound planetary gear train; the hollow shafts of the three sun gears are nested with each other, the power transmitted by the input shaft 1 is transmitted to the variable pump 16 through the meshing gear pair C17, and the quantitative motor 15 is transmitted to the clutch outer hub 13 through the meshing gear pair B14, and the hydraulic power is transmitted to the three sun gears through the switching of the clutch; The mechanical power is transmitted to the planetary frame rod 8 and output by the inner ring gear 7 after being merged. The transmission is simple in structure, easy to manufacture and assemble, and characterized by high transmission efficiency.
