N91 # system hydraulic regulating solenoid valve
Mixer's main function is in the process of vehicle, on the basis of the actual working condition of the vehicle and numerous real-time signal parameters on the system's oil pressure and hydraulic actuators work random adjustment, make the system's oil pressure is always in the scope of a relatively stable, not only to ensure that match the engine load, and to ensure that the actuator will not happen by abnormal hydraulic skid and into shock.
The characteristics of the electromagnetic valve
Pieces # N91 is a long solenoid valve closed, the pressure when the electricity, power pressure, with the introduction of the characteristics of the solenoid valve on the contrary, control mode belongs to the pulse width type.
N91 # is automatic transmission control system is one of the busiest actuators, don't like shift solenoid valve only in a particular gear are motivated, as long as open ignition switch, whether or not the engine running, shift lever in which position, # N91 stepped in normal working condition, in the process of vehicle, based on the powerful software program and several tests to establish a large number of empirical data, the control unit through the use of advanced Can bus, the vehicle control unit such as engine, traction, electric control suspension control system, and obtain the real-time data, to the current operating conditions must be calculated value of the hydraulic system, then put the oil pressure value converted to the corresponding duty ratio, terminal power triode in this duty instruction for # N91 drive, under the action of eventually formed a system of required pressure and real-time hydraulic actuators work.
Example # hydraulic regulating system N91 solenoid valve function

N92 # electromagnetic valve actuator oil pressure regulating function description
Mixer's main function is to control in the process of traffic entering 2/3/5 gear brake hydraulic D work
The characteristics of the electromagnetic valve
Mixer N92 # is a normally closed electromagnetic valves, pressure relief when electricity, namely pressure when power outages, control mode belongs to the pulse width type.
N92 example # electromagnetic valve actuator oil pressure regulating function
Mixer N92 # often energized the situation
As shown, N92 # often electricity, the pressure regulating valve and brake valve control hydraulic retracted, two valve on the left side of the spring force role right reset, brake oil C work connected with the pressure on the brake control valve mouth, under pressure to release.
Mixer N92 # often power outages
Low as shown, the N92 # often power outages, reduced pressure control oil pressure at the same time, the pressure regulating valve and brake valve, the valve in the oil pressure under the action of overcome the spring force on the left side of the shift to the left, the main oil pressure by the brake control valve into C brake, make the C brake.
When C brake into working state, working oil pressure on the pressure regulating valve is cut off.
Impose on the right side of the brake control valve with low pressure regulator on the left side of the control oil pressure, when N92 # power depends on the working state of the 2 # shift valve, if 2 # shift valve in original reset state, then the oil pressure will not be formed, if left 2 # shift valve, N92 # power formed by the control oil pressure by the 2 # shift valve on the pressure regulating valve and brake valve.
Can be seen from the diagram, on the right side of the brake control valve and pressure regulator on the left side of the control oil pressure, and N92 # power formed by the control oil pressure to the top of formation, its purpose is through to modulation of valve movement speed, so as to achieve the work C brake oil pressure flow and flow rate control, finally obtaining relatively soft feeling into the file.
These instructions are to N92 # solenoid valve function in the two extreme cases, in fact, the vehicle in the process of driving, N92 # electromagnetic valve is set the duty cycle of the job, only when the control unit to confirm the actual gear has been formed, there are serious or recognition to control circuit fault hidden trouble, N92 # solenoid valve work form essential changes, as shown.
Low motivation in N92 # solenoid valve controlled unit early, because duty is high, the pressure regulating valve and brake control valve on the right side of the control oil pressure is low, which prompted the two valve slowly move to the left, when C brake oil has just been opened and C on to get a throttle hydraulic brake at the same time, the throttle pressure by to the left of the brake control valve, pressure regulating valve feedback of brake control valve movements are suppressed, the valve movement speed slower, then lower duty ratio control unit, the pressure regulating valve and brake control valve on the right side of the control oil pressure increases, when the oil pressure regulator on the feedback and pressure mouth are interlinked, brake oil pressure control valve on the left side of the feedback is undone, moves to limit the position of the brake control valve to left, as hydraulic cylinders are completely open, C brake oil pressure will get a normal work.
Can be seen from the above analysis, the formation of C brake working oil pressure is not achieved overnight, there is a gradual process, this with previous actuator works on automatic transmission are quite different.
The N93 # electromagnetic valve actuator oil pressure regulating function description
Mixer's main function is to control in the process of traffic into 1/2 file with reverse/manual hydraulic brake "1 G work
The characteristics of the electromagnetic valve
In pieces the N93 # is a long solenoid valve closed, the pressure when the electricity, power pressure, control mode belongs to the pulse width type.
The N93 example # electromagnetic valve actuator oil pressure regulating function
In pieces the N93 # often energized the situation
As shown, the N93 # often electricity, the pressure regulating valve and brake valve control hydraulic retracted, two valve on the left side of the spring force action right move reset, brake oil G work connected with the pressure on the brake control valve mouth, under pressure to release.
Working circuit and low brake G C brake difference is set up circular hollow damping piece, to play the role of a buffer, avoid the combination of early shock.
In pieces the N93 # often power outages
As shown, the N93 # often power outages, reduced pressure control oil pressure at the same time, the pressure regulating valve and brake valve, the valve under the action of the oil pressure, overcome the spring force on the left side of the shift to the left, the main oil pressure by the brake control valve into the G brake, brake make G.
Low in G brake into the work state, working oil pressure on the pressure regulating valve is cut off.
Can be seen from the diagram, on the right side of the brake control valve and pressure regulator on the left side of the control oil pressure, and the N93 # power formed by the control oil pressure to the top of formation, its purpose is through to modulation of valve movement speed, so as to achieve the G work brake oil pressure flow and flow rate control, finally obtaining relatively soft feeling into the file.
To be sure, the above for N93 # solenoid valve function has certain limitation, in fact, as repair data description, in the process of vehicle, the N93 # electromagnetic valve is set by the duty ratio of the job, only when the control unit to confirm the actual gear has been formed, there are serious or recognition to control circuit fault hidden trouble, the N93 # solenoid valve work form essential changes, as shown.
Low motivation in the N93 # solenoid valve controlled unit early, because duty is high, the pressure regulating valve and brake control valve on the right side of the control oil pressure is low, which prompted the two valve slowly move to the left, brake oil has just been opened, when G G on to get a throttle hydraulic brake at the same time, the throttling oil pressure by the pressure regulator feedback to the left of the brake control valve, the brake control valve movements are suppressed, the valve movement speed slower, then lower duty ratio control unit, the pressure regulating valve and brake control valve on the right side of the control oil pressure increases, when the oil pressure regulator on the feedback and pressure mouth are interlinked, brake oil pressure control valve on the left side of the feedback is undone, moves to limit the position of the brake control valve to left, as hydraulic cylinders are completely open, G brake oil pressure will get a normal work.
Unlike C brake control circuit, pressure regulator in the feedback branch added a damping hole, hydraulic feedback on into the brake control valve the left cavity throttling, makes the movement of the brake control valve more smooth soft.
From the above analysis can also see, G work brake oil pressure is a gradual process, the formation of this basic same with C brake.
N94 # locking solenoid valve function description

The characteristics of the electromagnetic valve
Mixer N94 # is a duty to control electromagnetic valve, high duty cycle control oil pressure increases, when the duty cycle control oil pressure lower than hours, duty ratio is not a constant, changes over the state of the vehicle.
N94 # lock sample check electromagnetic valve function
As shown, when the N94 # locking the solenoid valve is in a state of pressure, on the lock directional valve with a locking commands on the left side of the valve on the right side of the control oil pressure release, the two valves in the reset state, the main oil pressure on the lock command valve is blocked, to independent hydraulic valve torque converter working oil pressure by locking control valve, torque converter's former cavity, cavity, after locking the reversing valve, locking control valve, check valve, formation pressure of oil and lubrication control valve for a mutual into the radiator, because
Time-varying cavity of the hydraulic basic equal before and after twisting machine, torque converter in a state of hydraulic transmission.
As shown, when the N94 # locking solenoid valve began to work in the form of duty ratio, the locking the reversing valve and locking command the left and right side will form control hydraulic valve, prompted the two valve position is changed, the first is the main hydraulic valve by the locking instructions to control oil pressure imposed on the right side of the lock check valve timing, forcing locking timing valve to overcome the spring force on the left of the left shift, release the cavity of the hydraulic torque converter ago, second is the job of the torque converter oil pressure by locking the reversing valve cavity after entering the torque converter, the huge cavity under the action of pressure difference before and after installation on the turbine friction plate moved forward with the inner surface of the pump wheel contact tightly together, and make the converter into a rigid body, the torque converter, in the form of mechanical transmission.
