How does the flagship 560 automatic Dongwo gearbox work?

This gearbox has good ride comfort and high reliability. The gearbox is a very important part of the vehicle, which can change the transmission ratio and expand the role of driving wheel torque and speed. With the development of modern science and technology, the gearbox has also been updated. From the original manual gearbox to the present stepless gearbox, from non-synchronizer to synchronizer, it is more and more convenient to control. At present, diesel engine is widely used in construction machinery, and its torque and speed change range is small, which can not meet the requirements of traction and running speed of vehicles under various working conditions. It is necessary to use gearbox to solve this contradiction. The performance of gearbox is the key to measure the power, economy and driving performance of construction machinery. At present, the transmission systems mainly include mechanical transmission, hydraulic transmission and hydrostatic transmission. The gearbox has manual shift and power shift, and the structure has fixed shaft type and planetary type. Manual gearbox is mainly composed of gears and shafts, which produce variable speed and torque through different gear combinations; Automatic gearbox AT is composed of hydraulic torque converter, planetary gear and hydraulic control system, which realizes variable speed and torque through hydraulic transmission and gear combination.
