Abstract

The invention discloses a dynamic gear-shifting speed changing box. The speed changing box comprises a speed changing box body. A first shaft and a second shaft are mounted in the speed changing box body. Five oil holes are formed in the second shaft in the axial direction, wherein four oil holes communicate with four wet clutches correspondingly, and the other oil hole serves as a lubricating oilway and is connected with an external hydraulic oil input pipeline. A dynamic gear-shifting speed changing box control system further comprises a suction filter, a gear pump, a booster filter, a control valve bank, a clutch electro-hydraulic valve bank, a lubrication system throttle valve, a gear power assisting device and an engine oil radiator. When the dynamic gear-shifting speed changing boxis loaded, the gear can be shifted without stamping on a clutch in the travelling process, the whole control system can precisely control hydraulic oil, the stability of a hydraulic system is guaranteed, accordingly, clutch gear engagement can be more stable, the impact strength of the tractor gear shifting traveling process is greatly reduced, the hydraulic control and lubrication oil way is formed in the speed changing box body and the shaft, and space distribution is reasonable.

Description

technical field [0001] The present invention relates to the technical field of gearboxes, and more specifically relates to a power shift gearbox and a gearbox control system. Background technique [0002] my country is a large agricultural country in the world, and it needs to support more than 1.3 billion people to eat. Food is the source of human life. With the continuous improvement of the degree of agricultural mechanization, the proportion of multifunctional tractors in agricultural machinery has reached more than 70%, so tractors are key and important equipment in agricultural production. Tractors have a wide range of work and can plow, harrow, ditch, sow, harvest, and transport. The functions of tractors cover all field operations in agricultural production. The working environment of tractors is very harsh, not only to adapt to various field operations in plains, but also to field operations in mountains, hills and paddy fields. Especially in the clay areas in the ...
