Oil pressurization after, to each valve of control system provide control oil, participate in the control of system；Simultaneously lubrication extra in mechanical box
Oil is withdrawn into hydrodynamic tank.Diesel engine one operates the pump and begins to work, forms 12 by hydraulic transmission gear box input shaft of the present invention
On gear driving, see attached drawing 4.
Secondary lubricating pump 19: for gear oil pump, highest charge oil pressure 392kPa (4kg/cm2).Its effect is from hydraulic transmission gear box
Middle pump participates in the lubrication of each oil site as lubricating oil；It pumps from hydraulic transmission gear box and participates in the control of transmission case as control oil
System；Lubricating oil extra in mechanical box is withdrawn into hydraulic transmission gear box simultaneously.Only in locomotive operation, the pump just works, by Q
Gear driving on the turbine wheel shaft of torque converter shaft, attached drawing 4.
Hydraulic changeover control valve 13: it is made of reversal valve, the vehicle in the same housing to valve and brake valve.Its effect is
Control the gear shift, commutation and implementation dynamic braking of transmission case.Wherein, reversal valve is by the control of control wind, and vehicle is to valve and braking
The control of the controlled liquefaction of valve.
Charge regulating valve 4: its effect is that locomotive is automatically closed in traction working condition, it is ensured that starting torque converter is in complete oil-filled shape
It works under state；Locomotive is automatically opened in damped condition, it is ensured that starting torque converter can only part it is oil-filled, to limit excessive braking
Power.
Shift valve: it acts on the control oil circuit for being on or off I grade and II grade of main control valve, to control starting torque converter
Or the filling of running torque converter, oil extraction.Shift valve 17 and is controlled wind by the control of controller and electric pneumatic valve by the control of control wind.
Control filter: it is to carry out filtering to control oil that it, which is acted on, to guarantee the cleannes of control oil.
Main control valve: its effect is the different location according to locating for the slide valve of main control valve, can be switched on or off starting
The filling of torque converter or running torque converter, oil outlet passage, complete the starting and gear shift of transmission case.Main control valve is by from hydraulic changeover
The control of the control oil of control valve 13 (reversal valve and vehicle to valve).
Control oil rectifier effect is the impurity in filtering control oil, is sent to shift valve 17；Lubricating oil purifier is made
With being mechanical tool impurity inside filtering lubricant oil, guarantee that clean lubricating oil enters each oil site.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
