Abstract

PURPOSE:To reduce the weight of a device, to decrease the machining man- hours, and to improve resistance to wear, by a method wherein a housing body is cast in an aluminium alloy, and iron-plating is applied on the inner surface for sliding formed inside the housing body. CONSTITUTION:The body 1 of a valve housing is die cast in an aluminium alloy in one body. Iron-plating is applied on the inner surface 4 for sliding to form an iron-plated layer 5. This enables reduction of the weight of a device, decrease of the machining man-hours, and sharp improvement of resistance to wear.

Description

【発明の詳細な説明】 本発明は、バルブハウジングに係り、特に、自動車用パ
ワーステアリングのバルブハウジングに関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a valve housing, and particularly to a valve housing for a power steering vehicle.

従来のバルブハウジングは、鉄系材料を用いて鋳造して
大略の形状を作り、それを機械加工して製造したもので
ある。Conventional valve housings are manufactured by casting an iron-based material into a rough shape and then machining the shape.

上記のバルブハウジングは、鉄製であるため重量が重く
て、自動車の軽量化の点で適当でなく、また、機械加工
も多くの工数を要するので量産的でない欠点があった。Since the above-mentioned valve housing is made of iron, it is heavy, making it unsuitable for reducing the weight of automobiles, and machining requires a large number of man-hours, making it difficult to mass-produce.

本発明は、このような欠点を解消したもので、軽量で量
産性に優れ、かつ、満足し得る耐摩耗性−１− を有するバルブハウジングの提供を、目的とするもので
ある。The present invention eliminates these drawbacks, and aims to provide a valve housing that is lightweight, suitable for mass production, and has satisfactory wear resistance.

本発明の構成は、バルブハウジング本体をアルミニウム

に鉄メッキを施したバルブハウジングにある。The structure of the present invention resides in a valve housing in which the valve housing body is cast from an aluminum alloy, and the sliding inner surface provided within the housing body is plated with iron.

以下、本発明の実施例を、図面に基づいて説明する。Embodiments of the present invention will be described below based on the drawings.

ここで、第１図は、一実施例に係るバルブハウジングの
正面図、第２図は、第１図のＡ−Ａ断面図である。Here, FIG. 1 is a front view of a valve housing according to one embodiment, and FIG. 2 is a sectional view taken along line AA in FIG. 1.

This is the sliding inner surface of hole 3. This sliding inner surface 4 is plated with iron to form an iron plating layer 5. For iron plating, hardness is 400Hv or more.
It provides the performance of a thickness of 10 μm or more, prevents galling, and has wear resistance.

できる。-2- As explained above, in the valve housing according to this embodiment, the valve housing main body 1 is integrally die-cast from an aluminum alloy, so that it is possible to reduce the weight and the number of machining steps. Moreover, since the sliding inner surface 4 is plated with iron to form the iron plating layer 5, the wear resistance of the aluminum alloy can be significantly improved.

的効果に優れた発明ということができる。As described above, since the valve housing of the present invention is cast from an aluminum alloy, it is possible to reduce the weight and the number of machining steps compared to conventional iron-made ones.
Further, since an iron plating layer is formed on the sliding inner surface, a valve housing having wear resistance can be expected, and the invention can be said to have excellent practical effects.
