Abstract

The invention discloses a continuously variable transmission of quick reversing power division hydraulic machinery. The continuously variable transmission comprises a transmission main body mechanism,a transmission gear shifting mechanism and an advancement-retreating switching mechanism; the transmission main body mechanism comprises a planet gear mechanism and a hydraulic transmission mechanism; the hydraulic transmission mechanism comprises a variable pump and a quantitative motor; an input shaft of the transmission divides engine power through the planet gear mechanism and the hydraulic transmission mechanism; mechanical power and hydraulic power are collected through a long planet gear; and the collected power is output to the transmission gear shifting mechanism through a small sungear shaft or a planet carrier, and is transferred to an output shaft of the transmission for outputting through the transmission gear shifting mechanism and the advancement-retreating switching mechanism. The transmission is more compact in structure and higher in economical benefit.

Description

technical field [0001] The invention belongs to the technical field of continuously variable transmission, and in particular relates to a rapid reversing power split hydraulic mechanical continuously variable transmission. Background technique [0002] The load of the vehicle is constantly changing under different road surfaces and different working conditions. Some high-power agricultural vehicles and engineering vehicles transmit large power, the working environment of the vehicle is harsh, and the load changes frequently. This requires the transmission to provide a reasonable speed and speed in a timely manner. Torque to meet the working requirements of the vehicle; at the same time, it is also necessary to take into account the power, fuel economy, comfort and handling stability of the vehicle. Stepped transmissions have limited gears, and can only transmit power according to a fixed transmission ratio, and cannot realize stepless transmission; increasing the gears of th...
