Abstract

The invention discloses a continuously variable transmission of double-planet five-section hydraulic machinery. A front speed change transmission box chamber comprises a double-planet speed change mechanism and a hydraulic speed change system arranged in parallel; the double-planet speed change mechanism comprises a power input shaft in transmission connection with a power end, a transmission shaft, an intermediate shaft and a speed change gear shifting mechanism; the power input shaft, the hydraulic speed change system, a double-planet row and a transmission shaft form a closed hydraulic unit; the stepless speed adjustment is realized under participation of the hydraulic speed change system; the hydraulic speed change system is a system of converting mechanical power flow to hydraulic power flow; the hydraulic speed change system can realize continuous change of the rotating speed; through the double-planet row, the continuous change of the speed ratio of the transmission can be realized; the advantages of low energy loss, high transfer efficiency and stable transmission are achieved; the total size of the transmission is reduced; the structure is compact; the five-section stepless speed change can be realized; the high-power output operation is facilitated; the transmission efficiency is prominently improved; different operation environments can be met; the structure is simple; and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to a double planetary five-stage hydraulic-mechanical continuously variable transmission. Background technique [0002] Hydraulic transmission has the advantages of convenient layout, high power density, output torque and speed are not affected by input speed, easy to realize stepless speed regulation and automatic control, etc., but at the same time, it has the disadvantages of low transmission efficiency, especially in high speed and low speed. In the transmission working condition, the deficiency of low transmission efficiency is more prominent. Gear mechanical transmission has the advantages of accurate and reliable transmission motion, constant instantaneous transmission ratio, compact structure, large transmission ratio, large transmission power and high transmission efficiency, but it is not easy to realize automatic transmission, let alone continuously variable transmi...
