Abstract
The utility model discloses a special-shaped steel tube of an automobile brake system. The special-shaped steel tube comprises a tube body and an inner hole, wherein the tube body is cylindrical; and the inner hole is oval, located in the center of the tube body, and is concentric with the tube body. Due to the arrangement, according to the special-shaped steel tube of the automobile brake system, product stability can be improved, service life is prolonged, the machining process is simple, and cost can be reduced.
Description
Technical field
The utility model relates to the technique of pipe field, particularly relates to a kind of automobile brake system steel tubes.
Background technique
The effect of automobile brake system is: make the automobile in travelling carry out forced deceleration even parking according to driver's requirement; Make the automobile of stagnation of movement (is included on the ramp) steadily halt under the different kinds of roads condition; Make the car speed of descent run keep stable.Therefore, very high to the requirement of the Security that is applied to the steel pipe on the automobile brake system, stability etc., and need to possess the characteristics such as quite long working life, fatigue resistance, corrosion resistance.The intensity of existing this class steel pipe is often inadequate, does not reach requirement.
The model utility content
The technical problem that the utility model mainly solves is: for the deficiencies in the prior art, provide a kind of automobile brake system steel tubes, can improve product stability, increase the service life, reduce cost.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of automobile brake system steel tubes is provided, comprises: body and endoporus, described body is the cylindrical shape body, described endoporus is oval endoporus, is positioned at the central authorities of described body, and is concentric with described body.
In preferred embodiment of the utility model, the concentricity of described body and described endoporus is less than or equal to 0.015mm.
In preferred embodiment of the utility model, the material of described automobile brake system steel tubes is the 20# seamless steel pipe.
The beneficial effects of the utility model are: the utility model has disclosed a kind of automobile brake system steel tubes, and the employing carbon constructional quality steel is material, and endoporus is made ellipse, can improve product stability, and increase the service life, and processing technology is simple, can reduce cost.
Description of drawings
Fig. 1 is the structural representation of the utility model automobile brake system steel tubes one preferred embodiment;
The mark of each parts is as follows in the accompanying drawing: 1, body, 2, endoporus.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also shown in Figure 1ly, the utility model is embodiment comprise:
A kind of automobile brake system steel tubes, its material selection 20# seamless steel pipe comprises: body 1 and endoporus 2, described body 1 is the cylindrical shape body, and described endoporus 2 is oval endoporus, is positioned at the central authorities of described body 1, concentric with described body 1, and its concentricity is in 0.015mm.
Automobile brake system steel tubes of the present utility model is selected the 20# seamless steel pipe, and directly cold drawn forming can guarantee that it reaches target hardness, and internal material is not organized and can be changed, the difficult crack that produces; Concentricity is controlled in the 0.015mm, can guarantee its product stability.
The utility model has disclosed a kind of automobile brake system steel tubes, and the employing carbon constructional quality steel is material, and endoporus is made ellipse, can improve product stability, and increase the service life, and processing technology is simple, can reduce cost.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
