Abstract

The utility model relates to an air throttle body, which comprises an air throttle body, a base, a swing frame arranged on the side of the body, an idle speed control valve and air throttle position sensor arranged on the other side. The utility model enlarges the through hole diameter at the lower end of main channel on the air throttle body, the symmetrical U groove is arranged on the edge of the swing frame, at least three fixing holes are arranged on the base. The utility model has the advantages of adopting plastic material as air throttle body with once-injection molding, which can not only economize costs but also lighten the weight, the three fixing holes arranged on the base can make the structure compact, reduce the quantity of fastening part and decrease the production costs.

Description

Throttle body

Technical field:

The utility model relates to a kind of throttle body, relates in particular to a kind of throttle body of automobile electronic fuel oil jet oil-fired system.

Technical background:

The throttle body of automobile use at present generally adopts metallic material to make, though metallic material has intensity and mechanical processing characteristic preferably, but proportion is bigger, price is more expensive, cause cost of production higher, and structurally also there are some irrational places in the throttle body that uses at present, so be necessary the structure of throttle body is improved.

Summary of the invention:

It is more expensive that the utility model has mainly solved throttle body manufactured materials price, and the cost of production problem of higher, provides a kind of rational in infrastructure, the throttle body that cost of production is lower

The technological scheme that its technical problem that solves the utility model adopts is: a kind of throttle body, comprise tb, base, be installed on the swing frame of body one side, and the IACV (Idle Air Control Valve) and the throttle position sensor that are installed on opposite side, the utility model has increased the bore dia of lower end, the main passage through hole of tb, described swing frame edge is provided with the U type groove of symmetry, and described base is provided with at least 3 mounting holes.Described throttle body adopts plastics PPS-GF20+GB40 material made, makes throttle body lightweight more, and the structure of swing frame changes the structure general with 479 into, and it is unitized to help part, has reduced cost.

As a kind of preferred version of such scheme, the bore dia of described throttle body lower end through hole equates with the bore dia of upper end through hole.Compare with original throttle body, increased the aperture of lower end through hole, help air inlet.

As a kind of preferred version of such scheme, equate at described U type groove both sides wall thickness, on one side the cell wall bottom extend out to axle and form a swing frame main body.This groove is the U-shaped of a symmetry, when rotating, helps the acceleration cable centering in the groove, has prevented from that acceleration cable from departing from the groove walls friction to cause wearing and tearing.

As a kind of preferred version of such scheme, described base is a triangle, and base is provided with 3 mounting holes, and described mounting hole is distributed in respectively on three ends of base angle.This is arranged so that structure is compact more, and has reduced the quantity of fastening piece, has reduced cost of production.

The utility model has the advantages that and adopt plastics as the throttle body manufactured materials, single injection-molded had both been saved cost, alleviated weight again, on base, be provided with 3 mounting holes, made structure compact more, reduce the quantity of fastening piece simultaneously, reduced cost of production.

Embodiment:

According to Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises tb 1, base 12, swing frame 6, IACV (Idle Air Control Valve) 9 and throttle position sensor 10.

As shown in Figure 4 and Figure 5, be provided with a main passage 2 in the tb 1, these main passage 3 upper and lower openings form upper end through hole 3 and lower end through hole 4, through hole 3 diameters and lower end through hole 4 equal diameters wherein, and 2 intermediate portion apertures, main passage are less than through-hole diameter up and down, the described center of circle of going up lower through-hole is not on same vertical line, and lower through-hole slightly is offset certain distance backward.One 11 according to Fig. 2 and shown in Figure 4, axle 11 1 ends are connected with a swing frame 6 in throttle body 1, and this swing frame is a fan shape, and the swing frame edge is provided with a symmetrical U-groove bevel 5, and the outward-dipping axle head that extends to forms swing frame main body 6 in cell wall bottom; According to shown in Figure 1, be connected with throttle position sensor 10 at axle 11 the other ends, be provided with IACV (Idle Air Control Valve) 9 in throttle position sensor one side.One base plate 12 is arranged on the throttle body bottom, and this bottom is a triangle, respectively is provided with a

mounting hole

7a, 7b, 7c at leg-of-mutton each end angle.
