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.

Description

technical field [0001] The invention relates to a speed change device of a small loader of 1 ton to 1.5 tons, in particular to a gearbox of a small loader with a new structure. Background technique [0002] At present, the small loader gearbox is basically in the form of 2-in, 2-reverse gear shifting. Both the forward gear clutch and the reverse gear clutch have two working chambers, and the maximum driving speed is about 20km / h, resulting in low work efficiency, high fuel consumption, and low work efficiency. The cost and consumption are large. Contents of the invention [0003] The purpose of the present invention is to provide a small loader gearbox with a new structure for the disadvantages of high clutch cost and low forward speed existing in the existing small loader. [0004] To achieve the above object, the present invention discloses the following technical solutions: [0005] A small loader gearbox with a new structure, including a box body, a hydraulic torque ...
