Abstract
The invention relates to a small loader gearbox with a new structure. An engine transmits torque into the gearbox through a hydraulic torque converter. An auxiliary input gear connected with the torque converter can drive an oil pump to work through a first gear. A main input gear transmits power to an output shaft through multiple levels of gears on a reverse gear clutch shaft, a forward gear clutch shaft and an intermediate shaft. A reverse gear clutch and a forward gear clutch can independently work, and accordingly the output shaft can be controlled to rotate forward and backward. The output rotating speed of the output shaft can be controlled by controlling the position of a sliding sleeve. A clutch is designed to be of a single cavity structure, meanwhile, outer ring transmission teeth are avoided, and therefore the transmission function is not achieved; thus, the integral failure of components due to damage of transmission teeth is avoided, material cost is saved, the machining technology is simplified, and the transmission reliability is guaranteed. The high gear and the low gear are switched on the output shaft through a shift fork, and operation reliability is facilitated.
