Description

Air throttle

Technical field

This utility model relates to auto parts and components product, specifically, relates to a kind of joint in automobile power assembly Valve.

Background technology

In internal combustion engine, be usually provided with throttle valve device, its be arranged in inlet manifold upstream and with admission line phase Even, for controlling to supply the air mass flow of inlet manifold, thus control to enter the air mass flow of cylinder.

The most general air throttle include air throttle housing, the motor being positioned at described air throttle enclosure interior and Throttle plate pin, the installation being connected fixed by the torque transmitter of the outfan engagement of described motor with described torque transmitter On described throttle plate pin, be positioned at the butterfly valve within gas channel, and coordinate the lid installed with air throttle housing.Wherein, Torque transmitter includes that intermeshing first gear and the second gear, described first gear are installed on the wheel shaft of housing also Being meshed with the outfan of motor, described throttle plate pin and the fixing connection of the second gear, described second gear is usually sector Taking turns, and it is provided with accepting groove, is used for fixing circular magnet, accepting groove inwall has two boss and the planar portions in circular magnet Coordinating, this sector gear also needs to arrange elastic catching, Magnet is fixed on a certain position so that follow-up injecting glue and solidification process In, the position of Magnet does not changes, and during throttle oscillations, elastic catching also can limit the displacement of Magnet.It addition, Also need on Magnet arrange a groove, with the groove fit on sector gear accepting groove, it is to avoid the installation direction mistake of Magnet.

But said structure has the drawback that 1) sector gear needs to arrange elastic catching and groove, and structure is complicated, adds Work cost is high；2) Magnet complex process, relatively costly；3) for realize same magnetic field intensity, plastics magnetic powder it is molded after mixing The injection Magnet of molding needs bigger volume, and quality is consequently increased.

Summary of the invention

The purpose of this utility model is to provide a kind of air throttle, and its simple in construction, processing cost is low.

The air throttle that this utility model provides, including: housing, it has gas channel；It is positioned at the motor of housing, this electricity Machine one end connects output gear；The torque transmitter engaged with described output gear；Fix with described torque transmitter The throttle plate pin connected, this throttle plate pin passes gas channel, and installs by inserting the first installing hole on housing and second Hole obtains and supports；It is arranged on described throttle plate pin, to be positioned at gas channel butterfly valve；It is fixed in torque transmitter Magnet, this Magnet is square.

It is preferred that described torque transmitter includes intermeshing first gear and the second gear, described first gear Being meshed with the output gear of motor, described second gear is fixing with throttle plate pin to be connected, and described square magnet is fixed on second In gear.

It is preferred that described second gear has the accepting groove housing square magnet, in this accepting groove, there is phase magnet Protruding.

It is preferred that the sidewall of described accepting groove is provided with gum-injecting port, this gum-injecting port has the inclined-plane extending to Magnet bottom surface.

It is preferred that described Magnet is formed by ferrum oxygen ferrum sintering, its volume is between 100 cubic millimeters to 400 cubic millimeters.

Compared with prior art, owing to Magnet is square, the second gear need not arrange elastic catching and fix Magnet, the most not The installation direction of Magnet is avoided to make a mistake with arranging groove with the groove fit on Magnet, simple in construction, and realize equal Magnetic field intensity lower volume little, processing cost is low.

Accompanying drawing explanation

The accompanying drawing of the part constituting the application is used for providing being further appreciated by of the present utility model, of the present utility model Schematic description and description is used for explaining this utility model, is not intended that improper restriction of the present utility model.At accompanying drawing In:

Fig. 1 is the generalized section after air throttle described in the utility model assembles；

Fig. 2 is the schematic perspective view that Magnet is installed on the second gear.

Detailed description of the invention

Referring to Fig. 1 to Fig. 2, this air throttle includes: housing 1, and it has gas channel 11；It is positioned at the motor of housing 1 2, this motor 2 one end connects output gear 21；The torque transmitter 3 engaged with described output gear 21；With described moment of torsion The fixing throttle plate pin 4 connected of transfer device 3, this throttle plate pin 4 passes gas channel 11, and by inserting leaning on housing 1 First installing hole 6 of nearly torque transmitter and the second installing hole 7 of its opposite side obtain and support；It is arranged on described throttle plate pin On 4, be positioned at the butterfly valve 5 of gas channel 11；The lid 8 coordinated with housing 1；This air throttle also includes being fixed on moment of torsion transmission dress Putting the Magnet 33 in 3, this Magnet 33 is square, including square or rectangle.Described torque transmitter 3 is secondary transmission, its Including intermeshing first gear 31 and the second gear 32, described first gear 31 is meshed with the output gear 21 of motor 2, Described second gear 32 is fixing with throttle plate pin 4 to be connected, and described square magnet 33 is fixed in the second gear 32.Described second tooth Wheel 32 has the accepting groove 321 housing square magnet 33, has the protruding (not shown) of phase magnet 33 in this accepting groove 321. Owing to Magnet 33 is square, the second gear 32 need not arrange elastic catching and fix Magnet 33, without arranging groove and Magnet On groove fit avoid the installation direction of Magnet to make a mistake, simple in construction, processing cost is low.On Magnet 33 also without Arranging groove again, technique is the simplest, and cost is lower.

The sidewall 322 of described accepting groove 321 is provided with gum-injecting port 323, and this gum-injecting port 323 has and extends to Magnet 33 bottom surface Inclined-plane.During installation, Magnet 33 is placed in the accepting groove 321 of the second gear 32, then injects glue, glue from gum-injecting port 323 It flow to Magnet 33 bottom surface, thus Magnet is fixed in the accepting groove 321 of the second gear 32.Described Magnet 33 is sintered by ferrum oxygen ferrum Forming, its volume is between 100 cubic millimeters to 400 cubic millimeters.Due to relatively high magnetism, Magnet 33 volume and mass ratio are existing Air throttle injection used Magnet is much smaller, so having only to less bond area and less glue, and can by Magnet By fixing.

Referring to Fig. 1, this air throttle also includes the return bullet that two ends are separately fixed on described housing 1 and the second gear 32 Spring 15, this return spring 15 is to be arranged on described housing 1 and the second gear 32, due to pretightning force with certain pretightning force Effect, one end of return spring 15 will pull the second gear 32 and be fixed on described housing 1, and this position is second The initial position of gear 32, when running into electric current and disconnecting, under the effect of above-mentioned pretightning force, described return spring 15 can pull Second gear 32 rotates, thus drives described throttle plate pin 4 to rotate and described dish valve 5 is withdrawn into initial position.Real at other Executing in example, this torque transmitter 3 can also be primary transmission.

Described air throttle also includes the electric interfaces (not shown) for powering on to described motor 2, is installed in lid 8 Position sensor (not shown), described position sensor by the anglec of rotation of dish valve 5 described in the change perception in Magnet 33 magnetic field, And feed back to electronic control unit.

Although this utility model discloses as above with preferred embodiment, but this utility model is not limited to this.Any Skilled person, the various changes made in without departing from spirit and scope of the present utility model and amendment, all should be included this in In the protection domain of utility model, protection domain the most of the present utility model should be as the criterion with claim limited range.
