  • Control Of Throttle Valves Provided In The Intake System Or In The Exhaust System (AREA)

Abstract

The utility model discloses a rotary proportion electromagnet for the electronic throttle control of an engine, which comprises a casing, wherein coils are arranged in the casing; a rotatable shaft is arranged at the center of the casing, and is connected with a rotary body by a driving pin; a connecting body is arranged on the front end of the rotary body; a torsional spring is arranged between the rotary body and the connecting body. The utility model adopts the rotary proportion electromagnet to control a throttle drew rod. Thus, the output torque is large, and the response speed is higher than that of a step motor; secondly, when an automobile suddenly loses electricity, the torsional spring can pull a throttle to the minimum position, so the reliability and the safety of running are increased; finally, a potentiometer of the rotary proportion electromagnet is provided with position feed back signals, and adopts the closed-loop control for the shaft displacement, so the running precision can be increased. The utility model has the advantages of high positional precision, good output force linearity, high reliability, high response speed, etc.

Description

The rotary proportion electro-magnet that is used for the Motronic control maps Throttle Opening Control
Technical field:
The utility model relate to a kind of be used for automobile electrically-controlled throttle rotary proportion electro-magnet, belong to the throttle actuator technical field.
Background technology:
Along with the Hyundai Motor industrial expansion, change original machinery control throttle into a kind of trend that electricity-controlling throttle has become automobile industry development, electricity-controlling throttle can improve engine power performance, economy and emission performance.Existing E-Gas actuator has electronic and two kinds of forms of air-operated control.The two ends of pneumatic mode actuator cylinder piston link to each other with atmosphere with draft tube respectively, adopt the mean pressure in the pressure control valve control cylinder; The actuator work of motor-type is to utilize the rotation of direct current motor or stepper motor and drive the swing of control rocking arm, and the aperture of air throttle is changed.The shortcoming of these two kinds of schemes is that response speed is slower when the accelerator rod stroke is longer, does not possess the self-return function under the situation of employing stepper motor or the unexpected dead electricity of direct current generator automobile, may cause the accident.
Summary of the invention:
The purpose of this utility model is: provide a kind of positional precision height, power output good linearity, reliability height, the fast rotary proportion electro-magnet that is used for the Motronic control maps Throttle Opening Control of response speed, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises housing (7), it is characterized in that: in housing (7), be provided with coil (8), in the middle of housing (7), be provided with rotatable axle (2), axle (2) is connected with rotor (10) by trundle (9), front end at rotor (10) is provided with connector (11), is provided with torsion spring (12) between rotor (10) and connector (11); Between axle (2) and housing (7), be provided with bearing (14); Outside housing (7), be provided with outer cover (15), between outer cover (15) and housing (7), be provided with O type circle (16); Between axle (2) and housing (7), be provided with oil sealing (17); In rotary proportion electro-magnet (1), be provided with pot (5).
Owing to adopted such scheme, the utility model to adopt rotary proportion electro-magnet control accelerator rod, the big and response speed of output torque is faster than stepper motor; Secondly torsion spring can be moved throttle to minimum position during the unexpected dead electricity of automobile, increases reliability of operation, security; The pot of last rotary proportion electro-magnet has position feed back signal, closed-loop control is adopted in displacement to axle, therefore can improve running precision, compare with prior art, the utlity model has advantages such as positional precision height, power output good linearity, reliability height, response speed be fast.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is a use synoptic diagram of the present utility model.
Embodiment:
Embodiment of the present utility model: rotary proportion electro-magnet (1) can be made according to following method: coil (8) is packed in the housing (7), and power lead passed from housing (7), a bearing (14) is installed respectively in the hole at housing (7) two ends, the left and right sides, the left side of axle (2) from housing (7) penetrated, at axle (2) right-hand member gasket ring (18) and rotor (10) are installed successively, with trundle (9) rotor (10) is linked to each other with axle (2), the torsion spring (12) of packing into successively again, connector (11) and swivel nut (13), and two arms of torsion spring (12) are separately fixed on connector (11) and the rotor (10), connector (11) is fixed on the housing (7) with screw (19), an oil sealing (17) is installed between axle (2) and housing (7), the O type of packing in the groove between housing (7) and outer cover circle (16), and outer cover (15) is fixed on the connector (11), go up at swivel nut (13) at last and a pot (5) is installed is got final product.
When rotary proportion electro-magnet (1) uses, rotary proportion electro-magnet (1) is installed near the accelerator rod position of motor car engine, the signal input part of rotary proportion electro-magnet (1) is connected to the signal output part of electronic accelerator controller (6), the axle (2) of rotary proportion electro-magnet (1) is connected with an end of connecting rod (3), and the other end of connecting rod (3) is connected with accelerator rod (4); Pot (5) is installed in rotary proportion electro-magnet (1), and pot (5) can adopt the TPS sensor, and the signal input part that pot (5) is connected to electronic accelerator controller (6) is got final product.After the signal Processing that electronic accelerator controller (6) transmits accelerator pedal position sensor, send command signal to rotary proportion electro-magnet (1), axle (2) motion of driven in rotation formula proportion electro-magnet (1), thereby the accelerator rod (4) that drives engine by axle (2) moves, and reaches the purpose of control engine oil mass size; And feed back the position signalling of axle (2) by pot (5), the command signal that transmits with accelerator pedal position sensor relatively after, adjust the displacement of axle (2) motion of rotary proportion electro-magnet (1), realize closed-loop control, the control accuracy of raising throttle.
