Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
Automatic transmission case clutch executive system, it is characterized by: it is made up of clutch executive system and clutch actuator control system, the clutch executive system is by a motor assembly 1, a pair of gear driving pair 2, a pair of power screw pair 3, master cylinder 6, wheel cylinder, power assistant spring 4, position transducer 5 is formed, motor assembly 1 is connected with the driving gear of gear driving pair 2, gear driving pair 2 is integrated and connected with power screw pair 3, be that the driven gear of gear driving pair 2 and the nut of power screw pair 3 are one, master cylinder 6 communicates with wheel cylinder, clutch control mainly is peripheral control circuit, the output terminal of peripheral control circuit is electrically connected with the input end of motor, and the input end of peripheral control circuit is electrically connected with position transducer 5.
The motor 1 of automatic transmission case clutch executive system is a direct current generator.
As shown in Figure 1,1 rotation of peripheral drive circuit control direct current generator, the rotation of motor 1 drives the small gear rotation that is fixed on the motor output shaft, small gear output passes to gearwheel by gear driving pair, the gearwheel rotation makes master cylinder 6 piston motions by power screw pair 3, the motion of piston makes front end master cylinder hydraulic pressure cavity set up pressure, thereby fluid pressure drives the purpose that the wheel cylinder motion reaches cut-off clutch.
Concrete working procedure is: when the ECU (Electrical Control Unit) of AMT system is sent the command control clutch separation, peripheral control circuit drive motor 1 is rotated in the forward, the rotation of motor 1 is by gear driving pair 2, power screw pair 3 is converted into the positive movement of master cylinder 6 pistons, because of hydraulic total pump and wheel cylinder are the intercommunication enclosed cavity, thereby intraluminal fluid is pressed oil to be subjected to piston pressure and is set up oil pressure, motion makes clutch separation thereby oil pressure promotes clutch slave cylinder, when position transducer 5 monitors when reaching the target location, peripheral control circuit is stopped power supply motor, makes clutch remain on current location.When solenoidoperated cluthes in conjunction with the time, peripheral control circuit provides motor counterrotating voltage, the rotation of motor makes the total pump piston reversing motion, fluid pressure descends in the master cylinder, cause active force that fluid pressure produces can not with the clutch separation equilibrium of forces, hydraulic oil flows back to master cylinder by wheel cylinder, the clutch combination.
