Description

Technical Field

[0001] The utility model relates to the technical field of gearboxes, in particular to an improved gearbox for agricultural machinery. Background Art

[0002] The gearbox (Transmission), also known as the transmission, is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in a fixed or divided manner. The working principle of the gearbox includes the principles of gear mechanics and levers. When downshifting, the passive gear is actually switched to a larger gear. According to the lever principle, the speed of the transmission output will be relatively reduced, but the torque will increase; conversely, when upshifting, the passive gear is actually switched to a small gear.
