Among the figure: an end of 1-coil, 2-stator, 3-rotor, 4-torsion spring, 5-torsion spring 4, the other end of 6-torsion spring, 7-eccentric wheel, 8-involute groove, 9-bearing, 10-connecting rod, 11-connection bent plate, 12-valve body, 13-valve rod, 14-valve block, 15-suction port, 16-spring shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Motor-driven electronic EGR valve is reversed in a kind of employing, comprises the valve block 14 that valve body 12, valve rod 13, valve rod 13 lower ends connect, and the lower end of valve body 12 is a suction port 15, is connected with through connection set on the valve rod 13 and reverses motor.
Connection set comprises the connection bent plate 11 that valve rod 13 upper ends connect; The eccentric wheel 7 that is connected with the rotor that reverses motor 3, torsion spring 4, eccentric wheel 7 is provided with involute groove 8; Connect bent plate 11 through connecting rod 10 connection bearings 9; Bearing 9 is configured in the involute groove 8 of eccentric wheel 7, and an end 5 of torsion spring 4 connects the stator 2 that reverses motor, and the other end 6 of torsion spring 4 is connected on the eccentric wheel 7.
Reverse motor and be made up of coil 1, stator 2 and rotor 3, rotor 3 is connected as a single entity through spring shaft 16 and eccentric wheel 7.The motor that reverses as shown in Figure 1 is to be wrapped on the stator 2 by coil 1, and rotor 3 can rotate in stator 2.The rotor 3 that reverses motor is connected as a single entity through spring shaft 16 and eccentric wheel 7.
The valve block 14 of valve rod 13 lower ends can be opened closed with the suction port 15 of valve body 12 lower ends.
Give the coil that reverses motor 1 energising as shown in Figures 2 and 3; Produce magnetic field in the stator 2 and make rotor 3 and eccentric wheel 7 rotations; The rotation of rotor 3 drives torsion spring 4 storage torsional moments, and bearing 9 is slided in the involute groove 8 of eccentric wheel 7, and bearing 9 links to each other with valve block 14 with valve rod 13 again; So valve rod 13 is moved downward, valve block 14 breaks away from the suction port 15 of valve bodies 12 and realizes the open function of electronic EGR valve.
When reducing to reverse the supply current of motor; The torsional moment of reversing motor reduces synchronously; Rotor 3 reverses under the flywheel moment effect of torsion spring 4 with eccentric wheel 7; Bearing 9 is reverse slide in the involute groove 8 of eccentric wheel 7, thereby drive valve rod 13 oppositely moves upward with valve block 14, thereby realizes the closing function of electronic EGR.
When the supply current that reverses motor was in a certain fixed value, the torsional moment of reversing motor equated that with the torsional moment of torsion spring 4 promptly rotor 3 is in a certain balance with spring 4, all no longer rotates, and is in a certain aperture even electronic EGR valve is stablized; Change the supply current that reverses motor, rotor 3 reaches balance again with spring 4, is in a certain new aperture thereby electronic EGR valve is stablized; Promptly realized electronic EGR valve linearity control.
It is proportional that the involute groove 8 of eccentric wheel 7 is designed to angle and involute radial displacement that eccentric wheel 7 rotates, thereby make the displacement of the driving current that reverses motor and valve block 14 proportional, thereby guaranteed the control accuracy of electronic EGR valve.
