Abstract
The utility model discloses a torque motor exhaust gas recirculation valve for an automobile. The torque motor exhaust gas recirculation valve for the automobile comprises a valve body, a torque motor is arranged in the valve body, the shaft end of a rotation shaft of the torque motor is connected with a magnetic steel tray in a sleeve mode, the upper end of the magnetic steel tray is provided with a groove, a permanent magnetic steel is fixedly arranged in the groove, an electronic Hall component connected with a PCB (printed circuit board) is arranged above the permanent magnetic steel, and the PCB is fixedly mounted on the inner wall of the valve body; the bottom of the groove is provided with a boss, the permanent magnetic steel is arranged on the boss, and the permanent magnetic steel is fixed onto the wall of the groove through laser welding; the distance between the permanent magnetic steel and the electronic Hall component 0.1 to 3 mm to obtain strong sensitivity; the electronic Hall component is a 360 electronic Hall component. The torque motor exhaust gas recirculation valve for the automobile has technical reliability, low production costs and a long service life.
Description
Technical field
The utility model relates to the improvement invention of exhaust gas recirculation valve for a kind of automobile, relates in particular to the improvement invention of torque motor formula exhaust gas recirculation valve for a kind of automobile.
Background technique
Automobile exhaust gas recirculation valve, utilize negative pressure of vacuum working principle, be mainly used in automobile engine tail gas releasing system, its most critical effect energy-conserving and environment-protective, to solve at present the optimal product of exhaust emissions, it can reduce nitrogen oxide and the hydrocarbon that engine high-temperature generates in vehicle traveling process, thereby makes exhaust emissions reach standard.
Prior art motor pps output signal adopts linear electron Hall 815 to manufacture, its shortcoming egr control accuracy in running is not high, during assembling, there is 0.3mm deviation electronics Hall and magnet steel position, may cause ECU to can't detect pps and valve body aperture position, cause the not up to standard or rate of fault while increasing automobilism of exhaust emissions.
Model utility content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of technology reliable, and cost is low, torque motor formula exhaust gas recirculation valve for the automobile of long service life.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme to realize: this kind of torque motor formula exhaust gas recirculation valve for automobile, include valve body, it is characterized in that: in described valve body, be provided with torque motor, the rotating shaft axial end of described torque motor is socketed with magnet steel pallet, and described magnet steel pallet upper end is provided with groove, is fixed with permanent-magnet steel in groove, described permanent-magnet steel top is provided with the electronics Hall of connection PCB circuit board, and PCB circuit board is fixedly mounted on valve interior wall.
Described groove bottom land is provided with boss, and permanent-magnet steel is arranged on boss, and permanent-magnet steel and groove cell wall are fixed by laser bonding.
Described permanent-magnet steel and electronics Hall spacing are 0.1 ~ 3mm.
Described electronics Hall is 360 electronics Halls.
The beneficial effects of the utility model are the torque motor formula exhaust gas recirculation valve for automobile after improving, its 360 electronics Hall can be programmed in line input voltage value with computer, more flexible, operating process is simple, the air inflow of reasonable controlled circulation valve, after improving, technology is reliable, and cost is low, and the working life that contactless sensing makes is elongated.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
Accompanying drawing has represented structure of the present utility model, further illustrates by reference to the accompanying drawings its details below again.Torque motor 1 formula exhaust gas recirculation valve for this automobile, include valve body, in described valve body, be provided with torque motor 1, rotating shaft 2 axial end of described torque motor 1 are socketed with magnet steel pallet 3, described magnet steel pallet 3 upper ends are provided with groove, in groove, be fixed with permanent-magnet steel 4, described permanent-magnet steel 4 tops are provided with the electronics Hall 5 of connection PCB circuit board 6, and PCB circuit board 6 is fixedly mounted on valve interior wall; Described groove bottom land is provided with boss, and permanent-magnet steel is arranged on boss, and permanent-magnet steel 6 is fixed by laser bonding with groove cell wall; Described permanent-magnet steel 6 is that 0.1 ~ 3mm makes induction stronger with electronics Hall 5 spacing; The model of described electronics Hall 5 is 360 electronics Halls.
The contactless 360 electronics Hall structural designs of employing new technology have replaced linear Hall 815 structures of prior art, in use show linear Hall 815, make automobile cannot accurately control Voltage-output when opening egr system, thereby ECU can not fine control waste gas inlet, utilize 360 electronics Halls can avoid the generation of this problem completely, this design utilizes permanent-magnet steel, Hall, PCB circuit board and electronic component form, during the discarded recycle valve work of EGR, machine shaft rotation, Hall is subject to influence of magnetic field, voltage change thereupon, this signal voltage directly flows to ECU and controls the number that exhausted air quantity enters, product structure is simple, during production, Hall can be programmed in line input voltage value with computer, relatively flexibility, operating process is simple, after improving, technology is reliable, cost is low, long service life.
