Abstract

The utility model relates to a combined type impeller for booster. In particular to a composite impeller for diffusion on an automobile supercharger. It comprises a wheel body. The wheel body contains two solid horn portions with the same shape, and the two solid horn portions are cast into a whole in a mouth-to-mouth shape. The outer side surfaces of the two solid horn parts are circumferentially and uniformly provided with blades. Wherein the blades are helical. By adopting the composite impeller, the number of superchargers can be reduced, the installation space is reduced, the steel consumption is reduced, and the production cost is reduced.

Description

Composite impeller for supercharger

Technical Field

The utility model relates to a booster impeller. In particular to a composite impeller for diffusion on an automobile supercharger.

Background

It is known in the automotive industry to increase the power of an engine by providing a supercharger on the engine with a constant displacement. Wherein, the impellers used on the supercharger are all traditional impellers. The impeller has a solid horn-shaped impeller body, and blades are uniformly distributed on the periphery of the impeller body. The booster boost effect of the use of such impellers is limited because they have only one solid flared wheel body. To further increase the power of an automobile engine, it is conventional to increase the number of superchargers. Therefore, many automobiles are provided with two superchargers. Although the power of the engine can be further improved by increasing the number of the superchargers, the engine consumes more steel, has high production cost and occupies larger installation space.

SUMMERY OF THE UTILITY MODEL

The to-be-solved problem of the utility model is to overcome above-mentioned not enough, provide a combined type impeller for booster. The composite impeller can reduce the number of superchargers, installation space, steel consumption and production cost.

The utility model discloses the above-mentioned problem that solves is realized by following technical scheme:

the utility model discloses a combined type impeller for booster includes the wheel body. The wheel body contains two solid horn portions with the same shape, and the two solid horn portions are cast into a whole in a mouth-to-mouth shape. The outer side surfaces of the two solid horn parts are circumferentially and uniformly provided with blades. Wherein the blades are helical.

Wherein: the non-flared "mouth" ends of the solid flares each project beyond the outer ends of the blades thereon.

According to the scheme, the wheel body comprises the two solid horn parts with the same shape, and the two solid horn parts are cast into a whole in a mouth-to-mouth shape. The single horn-shaped impeller is replaced by a composite impeller formed by butt joint of two solid horn parts in a horn mouth-to-mouth mode, so that one supercharger can achieve the supercharging effect of two superchargers. Not only reduces the number of the superchargers and the installation space, but also reduces the consumption of steel and the production cost.

Drawings

Fig. 1 is a schematic view of a composite impeller for a supercharger according to the present invention;

fig. 2 is a sectional view a-a of fig. 1.

Detailed Description

As shown in fig. 1 and 2, the composite impeller for a supercharger of the present invention includes a wheel body 1. The wheel body 1 comprises two solid horn parts with the same shape, and the two solid horn parts are cast into a whole in a mouth-to-mouth shape. The outer side surfaces of the two solid horn parts are circumferentially and uniformly provided with blades 2. The blade 2 is a helical blade.

Wherein the non-flared "mouth" ends 3 of the solid flares each project beyond the outer ends of the vanes 2 thereon.

The utility model discloses change single tubaeform impeller into and be "horn mouth to mouth" the combined type impeller that the butt joint formed by two solid horn portions for a booster just can play the pressure boost effect of two superchargers.

Claims

1. The composite impeller for the supercharger comprises a wheel body and blades; the method is characterized in that: the wheel body comprises two solid horn parts with the same shape, and the two solid horn parts are cast into a whole in a mouth-to-mouth shape; the blades are uniformly distributed on the outer side surfaces of the two solid horn parts in the circumferential direction.

2. The composite impeller for a supercharger according to claim 1, wherein: the non-flared "mouth" ends of the solid flares each project beyond the outer ends of the blades thereon.
