In above-mentioned technical scheme, a kind of speed change tank drainback injection lubricating arrangement provided by the utility model can be with
According to the application operating mode of different gearboxes, oil return flange is adjusted, to reach different injection purposes, in addition to preventing
Direct oil return produces big gauging foam, increases hydraulic fluid port baffle plate in oil return flange front end, can adjust the pressure of surrounding jet, and can
Remaining oil return is gone downstream along casing side, so as to substantially increase the service efficiency of oil return, greatly reduce
Oily foam is produced under a large amount of oil return states.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the connection diagram between the utility model and return line, oil return opening；
Fig. 3 is schematic view of the mounting position of the utility model on gearbox.
Embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 1 to Fig. 3, a kind of speed change tank drainback injection lubricating arrangement provided by the utility model, connect
Between oil return opening 4 on torque-converters oil return pipe 1, gearbox oil return pipe 2 and gear box casing 3, including oil return flange and hydraulic fluid port gear
Plate 5, oil inlet 6, oil-out 7 and several jets 8 are provided with oil return flange, hydraulic fluid port baffle plate 5 is connected to oil return flange
Front end, oil return flange includes base 9 and oil nozzle 10 again, and the rear end of oil nozzle 10 is connected on the leading flank of base 9 so that oil return method
The shape of a boss is integrally formed in orchid, and hydraulic fluid port baffle plate 5 is connected to the front end of oil nozzle 10 by screw 13, can adjust each around
The pressure of individual jet 8, and can make remaining oil return all along the side inside gear box casing 3 smoothly and under, while can prevent
Only evoke oily foam in remaining loop hydraulic oil spurts to casing, base 9 is connected to the outside of gear box casing 3 by bolt 11
On face, oil nozzle 10 is set just to insert in the oil return opening 4 on gear box casing 3, oil inlet 6 is opened on base 9, and oil inlet 6 is again
It is connected respectively with torque-converters oil return pipe 1, gearbox oil return pipe 2 by tee pipe coupling 12, oil-out 7 is opened in oil nozzle 10
On, it is connected between oil inlet 6 and oil-out 7, several jets 8 are opened up on oil nozzle 10, and are connected with oil-out 7, profit
With the return pressure of torque-converters oil return pipe 1 and gearbox oil return pipe 2 (direction of arrow in such as Fig. 2), allow in each oil return pipe
On gear and bearing in hydraulic pressure oil spurts to gear box casing 3, to have the function that to strengthen gearbox lubrication.
Preferably, be additionally provided with sealed groove 13 on described oil nozzle 10, to place O-ring seal 14, make oil nozzle 10 with
