It is fixed with the rotation axis of speed changer.The external oil pump of the utility model facilitates installation, is also convenient for for different transmission types
Or the model of model replacement oil pump.
Preferably, the external oil pump of the utility model includes the first oil circuit and the second oil circuit, when the main shaft is with the first rotation
When turning direction and rotating, first oil circuit is oil inlet oil circuit, and the second oil circuit is fuel-displaced oil circuit；When the main shaft is with the second rotation side
To when rotation, second oil circuit is oil inlet oil circuit, and the first oil circuit is fuel-displaced oil circuit.One end of the stretching of the main shaft is inserted into
It is fixed in the rotation axis axle center hole of the speed changer.It is furthermore preferred that the axle center hole spiral shell of one end of the main shaft and the rotation axis
Close connection, the outer shell rivething of termination section and the speed changer.
Fig. 1 is the working principle diagram of the two-speed automatic transmission of one embodiment of the utility model.As shown in Figure 1, two
Speed automatic transmission is two axis structures, and it includes input axle assembly I, countershaft assembly M, output assembly O and shells 1.It should
Input axle assembly I, countershaft assembly M, the rotation centerline of output assembly O are parallel, and input axle assembly I, countershaft assembly
M, output assembly O is installed on shell.The input axle assembly I includes input shaft, gear a driving gear shaft, second gear master
Movable gear shaft, a gear gear shifting actuating mechanism A1, second gear gear shifting actuating mechanism A2, a gear clutch C1, second gear clutch C2 etc..In
Between axle assembly M include jackshaft, a gear driven gear, second gear driven gear, main reducing gear driving gear etc..Export assembly O packet
Driven gear containing main reducing gear, differential assembly etc..
In this embodiment, a gear gear shifting actuating mechanism A1, second gear gear shifting actuating mechanism A2, a gear clutch C1 and two
