The planet gear type gear-box axle of the most configurations of present domestic wheel loader is apart from big; Output speed is low, and what gearbox was installed simultaneously is the mechanical changeover control valve, can't adapt to the high efficiency operating mode pattern in bulk material market; And shift impact is big, and the driver operation travelling comfort is poor.
The model utility content
The purpose of the utility model just provides a kind of shortening wheelbase, and gear can be done lessly, is beneficial to the layout of gear in gearbox, can realize high-revolving output.Dispose electrically-controlled valve simultaneously, shift gears through the input of electrical signal, shift impact is little, the SWB gearbox that the driver operation travelling comfort is good.
The solution of the utility model is such: the utility model comprises input one-level gear and input secondary gear; Free wheel device is installed on the casing; Shaftgear and outer ring gear are meshed with input secondary gear and input one-level gear respectively; The spline of shaftgear is connected with the spline of sun gear; Sun gear is meshed with planet wheel that reverse gear planet row, one grade of planet are arranged simultaneously and is connected with the direct high axle, directly keeps off gear and output shaft gear is meshed, and the wheelbase of described direct retaining gear and output shaft gear is 344.5～373.75mm.
At said gearbox an electrically-controlled valve has been installed, described electrically-controlled valve has 3 hydraulic oil delivery outlets, leads to the described planet row clutch that reverses gear, a retaining planet row clutch, direct drive clutch respectively.
The utility model has the advantages that the shortening wheelbase, gear can be done lessly, is beneficial to the layout of gear in gearbox, can realize high-revolving output.Dispose electrically-controlled valve simultaneously, shift gears through the input of electrical signal, shift impact is little, and the driver operation travelling comfort is good.
