Abstract

The utility model discloses an engine aluminum casting capable of reducing noise. A wavy curved face is cast on the surface of the engine aluminum casting. The adopting aluminum casting reduces weight of an engine, accordingly reduces engine vibration, reduces noise, lowers fuel rate of the engine and well fits tendency of automobile development. Further, a large planar face is completely modified into the wavy curved face by optimizing original parts in design so as to form the means of mesh-like reinforcing ribs to achieve the effect of reducing nose, and thereby the engine aluminum casting avoids additional parts, beatifies the engine, increases engine quality and reduces engine cost.

Description

Engine aluminum casting that can noise reduction

Technical field

The utility model relates to a kind of engine aluminum casting, particularly a kind of engine aluminum casting that can noise reduction.

Background technique

At present, noise is one of a measured engine quality very important parameters.The general noise that reduces motor all is to wait and realize by raising element precision, increase sound arrester, increase beam, but improve the cost that element precision can increase motor, increase sound arrester and beam and can increase the part of motor, and be subjected to the restriction in space to be difficult for sometimes realizing.

Develop rapidly along with science and technology, the formation of Hyundai Motor manufactured materials, bigger variation has taken place, the ratio of high density material descends, low-density material has increase by a relatively large margin, the application area of non-ferrous metal is in continuous expansion, automotive material to lightweight, economize on resources, high-performance and high function direction develop.Hyundai Motor uses aluminum alloy material more and more.Aluminum alloy material is being played the part of very important role in the lightweight of Hyundai Motor, be considered to 21 century to be imbued with " green material " of development and application potentiality most.Therefore the Security of using aluminum alloy material can improve automobile is subjected to the favor of automobile sector day by day.Wherein the use of cast aluminium alloy on automobile is maximum, as the Al-alloy parts that adopt such as the oil sump of motor, cylinder head cover, gear chamber cover, flywheel casing more.

Summary of the invention

The utility model provides a kind of engine aluminum casting that can noise reduction for solving the technical problem that exists in the known technology.

The utility model for the technological scheme that solves the technical problem that exists in the known technology and take is: a kind of engine aluminum casting that can noise reduction, the surface of described engine aluminum casting is cast with the waveform curved surface.

The surface of described engine aluminum casting is cast with latticed stiffening rib.

Advantage and the good effect that the utlity model has are: owing to adopted aluminum casting, alleviated the weight of motor, thereby alleviated the vibration of motor, reduced noise, the fuelling rate of motor is descended, met very much the trend of development of automobile; Further, the utility model adopts optimal design on original part, wavy curved surface is all made on big plane, the mode that forms latticed stiffening rib reaches the effect that reduces noise, promptly do not increase part, can beautify motor again, improve the quality of motor, reduce the cost of motor.

Description of drawings

Fig. 1 implements engine sump tank structural representation of the present utility model;

Fig. 2 is the plan view of Fig. 1.

Among the figure: 1, curved surface, 2, stiffening rib.

Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1～Fig. 2, a kind of engine aluminum casting that can noise reduction, the surface of described engine aluminum casting is cast with waveform curved surface 1.The surface of described engine aluminum casting is cast with latticed stiffening rib 2.The form that curvecd surface type reticulates stiffening rib is all made on the surface, avoids the design on big plane, has increased the intensity of part, has effectively reduced the noise of motor, and has increased the heat diffusion area of motor.

Shown in Fig. 1～Fig. 2 is the oil sump of motor, aluminum castings such as the cylinder head cover of motor, gear chamber cover, flywheel casing can adopt the said structure design equally, do not increase engine part quantity, do not increasing under the prerequisite of starting manufacture cost to reach, reducing the noise of motor.

Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.

Claims (2)

1. One kind can noise reduction engine aluminum casting, it is characterized in that the surface of described engine aluminum casting is cast with the waveform curved surface.
2. 2. engine aluminum casting that can noise reduction according to claim 1 is characterized in that the surface of described engine aluminum casting is cast with latticed stiffening rib.
