The working principle of the invention is as follows:
1) electronic gear shifting
According to the invention, a manual valve mechanism in an automatic transmission is cancelled, two switch electromagnetic valves are designed to respectively control two groups of two-position three-way mechanical valve cores, and the two groups of two-position three-way mechanical valve cores are used for realizing switching of a P/R/N/D gear oil circuit, and the specific strategy is as follows:
1. s1 is not electrified, S2 is not electrified
The oil supply end of the clutch is filled with oil, the oil drain state is at the oil way of the N/P gear, the oil supply state is not at the R gear, and the oil is supplied at the D gear;
2. s1 is not electrified, S2 is electrified
The oil supply end of the D-gear clutch is cut off, the oil drainage state is realized at the oil way of the P-gear, and the oil supply state is not realized at the oil way of the R-gear, so that the oil supply way of the N-gear is realized;
3. s1 is electrified, S2 is not electrified
The oil supply of the D-gear clutch is cut off, the parking logic valve enables the oil supply of the parking piston to be cut off forcibly, and at the moment, the electromagnetic valve is cut off to realize a P-gear oil supply oil way;
4. s1 power-on, S2 power-on
The oil supply ends of the C3 and C4 clutches are independently filled with oil, and a reverse gear oil circuit is realized by combining the independent oil supply of B2; the two combined power flows can realize reverse gear, so that two-gear reverse gear can be realized;
2) oil supply for electromagnetic valve direct clutch
In the forward gear, the power supply is kept at S1, the power supply is kept at S2, the oil pressure is built up by the pump of the mechanical pump 1, and the ATF supplies oil to the inlets of the electromagnetic valves through the 1# oil way, the gear-shifting safety valve B, the 23# oil way and the 25# oil way.
In the invention, each clutch is controlled by an independent electromagnetic valve, namely 6 friction transmission assemblies are controlled by the same 6 NL VFS electromagnetic valves, and oil supply of inlets of the electromagnetic valves of all gears is not required to be switched by matching of a switch valve and a mechanical valve core when all gears of a D gear are switched, so that the gear-shifting time is greatly shortened, and the gear-shifting responsiveness is improved.
3) Electronic start-stop
The invention adopts an internal plunger pump to start and stop to replace the original external electronic pump, the plunger pump and the pressure release valve are arranged on the mechanical pump, the start-stop oil path consists of the plunger pump, a start-stop pressure release electromagnetic valve, a start-stop control valve component and an oil supply oil path, and the working principle is as follows: under the urban working condition, idling is stopped, an engine is shut down, a mechanical pump stops rotating, the start-stop plunger pump is controlled to work at the moment, oil pressure enters a C1 control oil path through a start-stop valve, a C1 clutch is compressed, a clutch piston is pushed to complete the stroke, and the oil pressure of a C1 clutch is kept above a KP point. When the engine is restarted, the mechanical pump works again after the engine reaches a certain rotating speed, and the oil pressure of the main oil way continuously rises. Under the pressure of the main oil way, the start-stop valve moves leftwards to push the steel ball to cut off the oil supply oil way of the plunger pump, and at the moment, the start-stop valve is withdrawn. After the plunger pump is stopped from starting and stopping, an oil drainage oil way is not provided for the plunger pump, oil drainage needs to be forced, and the pressure relief solenoid valve is started and stopped at a certain frequency to switch on and off, so that pressure relief is completed.
4) Electronic parking
The electronic control parking function comprises an S4 switch valve (NL), a parking mechanical valve component, a hydraulic cylinder piston and a parking electromagnetic valve, wherein the parking electromagnetic valve is a locking electromagnetic valve, the force required by the action of a locking pin is smaller than 30N when the parking electromagnetic valve is electrified, and the force required by the action of the locking pin is larger than 80N when the parking electromagnetic valve is not electrified. The parking mechanical valve assembly comprises a switch valve and a feedback valve, and is controlled by the switch valve S4. The working principle of the invention patent is as follows: when the vehicle is parked in the P gear, the main oil path supplies oil to the left end of the parking mechanical valve assembly through the valve gear shifting safety valve and the gear shifting logic valve, the main oil path is cut off to supply oil to the hydraulic cylinder, the piston loses thrust, S4 is not electrified at the moment, the force required by the action of the locking pin is larger than 80N, the power of the locking pin cannot be overcome by the return spring, and the parking control shaft is locked in the P gear by the parking electromagnetic valve.
And (3) P discharging process: the shifting safety valve and the shifting logic are controlled by switching on and off the switch valves S1 and S2, the main oil circuit is controlled to supply oil to the D-gear oil circuit, and the main oil circuit is cut off to supply oil to the P-gear oil circuit. And electrifying the switch valve S4, moving a switch valve spool leftwards under the control of the oil pressure at an outlet of the switch valve S4, filling oil into the hydraulic cylinder by the main oil line, pushing a piston of the hydraulic cylinder to move downwards after the hydraulic cylinder is filled with the oil, pushing the control shaft to enter a non-P gear, and releasing the P gear locking.
When the vehicle enters a non-P gear, S4 is powered off, the feedback valve in the parking mechanical valve component moves rightwards, and oil drainage is carried out on the oil pressure of the hydraulic cylinder. However, the parking piston (parking control shaft) is locked at the non-P-range position by the parking lock solenoid valve.
Entering P process (non-P gear): and the shifting safety valve and the shifting logic are controlled by switching on and off the switching valves S1 and S2, the main oil circuit is controlled to supply oil to the P-gear oil circuit, and the main oil circuit is cut off to supply oil to the non-P-gear oil circuit. Meanwhile, the parking electromagnetic valve is electrified, the force required by the action of the locking pin is smaller than 30N, the parking piston enters the P gear position under the action of the return spring force, then the parking electromagnetic valve is powered off, and the parking piston is locked at the P gear position.
The application does not relate to the improvement of other gear oil passages except for the P/R/N/D gear oil passage, so that the other gear oil passages except for the P/R/N/D gear oil passage are consistent with the traditional working oil passage switching method.
This embodiment is only illustrative of the patent and does not limit the scope of protection thereof, and those skilled in the art can make modifications to its part without departing from the spirit of the patent.
