Description

Integral type casting of automobile driving axle housing

Technical field

The utility model relates to a kind of integral type casting of automobile driving axle housing, and it belongs to the Machining Technology field.

Background technology

At present, the casting driving axle housing of producing both at home and abroad all adopts syllogic, and promptly centre housing adopts cast iron or cast steel casting to form, and the two ends central siphon inserts the housing two ends after independently processing again.This technical matters is complicated, workpiece weight is bigger, waste material, and also central siphon inserts the position truncation surface and suddenlys change easily, very easily ruptures.

The utility model content

The utility model is to deficiency of the prior art, provides that a kind of processing technology is simple, precision good, intensity is high and the integral type casting of automobile driving axle housing of good looking appearance.

The technical scheme that the utility model solves the problems of the technologies described above is following:

A kind of integral type casting of automobile driving axle housing comprises casting integrated housing and the central siphon that is located at its two ends.

Compared with prior art, the beneficial effect of the utility model is: structure design is simple, convenient processing, and intensity and precision are higher.

On the basis of technique scheme, the utility model can also be done following improvement.

Further, said housing is a rectangular cross section, and the middle part is provided with the Chinese lute hole; Said central siphon is a circular cross section.

Adopt the beneficial effect of above-mentioned further scheme to be: the shaped design of housing and central siphon, make outward appearance more attractive in appearance, make processing technology simpler simultaneously; Retarder can be conveniently installed in the setting in Chinese lute hole.

The specific embodiment

Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.

A kind of integral type casting of automobile driving axle housing comprises casting integrated housing 1 and the central siphon 2 that is located at its two ends; Said housing 1 is a rectangular cross section, and the middle part is provided with Chinese lute hole 3; Said central siphon 2 is a circular cross section.

The utility model is adding man-hour, and whole material can be cast iron or cast steel; The rectangular cross section size of housing 1 is generally (80～170) mm * (80～170) mm; The external diameter of the installation bearing portion of central siphon 2 is generally 50～120mm.

According to user demand, can select to make cylinder iron or cast steel; The length of housing 1 cross dimensions and thickness, central siphon 2 and cross dimensions can require really according to vehicle bridge institute's bearing load and car load.

The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
