Technical Field
The invention relates to the technical field of transmission, in particular to a power reversing speed change assembly and a high-low gear reversing system.
Background
At present, the gear shifting of the domestic tractor transmission system mainly adopts a meshing sleeve or a synchronizer, and the reversing mainly adopts a sliding gear, the meshing sleeve or the synchronizer. When shifting and reversing, the main clutch needs to be separated, the power transmission of the tractor is cut off, and then the gear shifting and reversing operation is carried out through the operating lever. The mode is simple and reliable, and the manufacturing cost is low. However, the labor intensity of the driver is relatively high when the driver frequently operates, and the reverse gear number is small, so that the driver operation requirement cannot be well met. Therefore, it is highly desirable to provide a transmission system that is easy to operate and has a large number of reverse gears to meet the wide range of tractor speeds.
