As executor, this is because electromagnetic valve can directly control distributive value and injection timing, part injection rate can also use electromagnetism
Valve realizes.So, three item controlled only executors just can complete, and the hardware making whole electronic system can
To be greatly simplified, therefore, electromagnetic valve one of of paramount importance parts in being current automatic gear-box.
Using electromagnetic valve as the executor of the electric-control system of electromotor, it is possible not only to use switch electromagnetic valve to carry out oil circuit control
Break-make, it is also possible to use variable current electromagnetic valve realize the regulation to oil pressure, such as will make in the control of clutch
Use variable current electromagnetic valve.The gearshift control mode of automatic gear-box is speed and two parameters of throttle opening amount signal to be turned
Chemical conversion control signal, according to the schedule set, is added to the two ends of shift valve by oil pressure, to control the position of shift valve, from
And change the oil circuit of shift clutch.So, working solution force feed enters corresponding executive component, makes clutch combine or separates,
Control planetary upshift or downshift, thus realize gearshift.
It addition, electromagnetic valve is combined regulation oil pressure have certain delayed lack with the pressure accumulation structure in automatic gear-box
Fall into, increase design difficulty and waste design space, because the response of electromagnetic valve self feeds back to automatic gear-box by oil circuit again
On pressure accumulation structure pressure store, wait electromagnetic valve response after, oil pressure is supplemented to electromagnetic valve again by pressure accumulation structure, so needing back and forth
Want the time, add the response time that oil pressure is complementary, be easily caused shift speed slow.
