    • An anti-vibration apparatus for an automotive hydraulic braking system for preventing the brake vibration by means of imparting the function of absorbing the pulsation of the hydraulic braking fluid pressure to any one structural member of the braking system, which is disposed in the hydraulic, braking fluid circuit, with respective proper object, such as a three-way joint, a pressure control valve, a wheel cylinder, etc. This apparatus is constructed in communication with the fluid passage within the respective structural member and comprises a cylinder formed integrally with the structural member body, a plunger slidably and fluid-tightly fitted in the cylinder, one end thereof being under the pressure of the hydraulic braking fluid and the other end thereof being faced to an air chamber, a stopper for restricting the axial sliding of the plunger within a limited range, and a spring for constantly biasing the plunger against the hydraulic braking fluid pressure.
    • 一种用于汽车液压制动系统的防振装置,用于通过赋予制动系统的任何一个结构构件来吸收液压制动流体压力的脉动的功能来防止制动器振动,该结构构件设置在液压制动 流体回路,具有相应适当的物体,例如三通接头,压力控制阀,轮缸等。该设备构造成与各个结构构件内的流体通道连通,并且包括与 结构构件主体,可滑动并且流体紧密地装配在气缸中的柱塞,其一端处于液压制动流体的压力下,另一端面向气室,用于限制柱塞的轴向滑动的止动件 在有限的范围内,以及弹簧,用于不断地使柱塞抵抗液压制动流体的压力。

    • An improved method of manufacturing a strut member for use in a strut device of the drum brake, having two strut members and a connecting member provided with a threaded portion for linking both, to function as an adjustor of the shoe clearance. This manufacturing method comprises as least the following two processes: (a) forming a flat plate-like portion partially on a length of a tube while producing a through bore therein as a displaced space, by inserting a mandrel substantially concentrically into a tube material, pressing or squeezing a portion of the tube in the diametrical direction in such a manner that the inside of the tube is pressed onto the mandrel for producing the displaced space therein, after retracting the mandrel until the inside surface of the tube at upper and lower portion thereof on either side of the displaced space closely contact to each other; and (b) forming a cut-out, ranging from the extremity of the tube to a part of the flattened portion, such that the through bore can have the opening thereof at the bottom of the cut-out to be able to engage with the web portion of a brake shoe.
    • 一种制造用于鼓式制动器的支柱装置的支柱构件的改进方法,具有两个支柱构件和连接构件,该连接构件设置有用于连接两者的螺纹部分,用作鞋间隙的调节器。 该制造方法至少包括以下两个过程:(a)在管的长度上部分地形成平板状部分,同时通过将心轴基本上同心地插入管材中而在其中形成作为置换空间的通孔, 在径向方向上挤压或挤压管的一部分,使得将管内部压在心轴上以在其中产生置换的空间之后,在缩回心轴之后直到管的上表面和下部 在位移空间的任一侧彼此紧密接触; 和(b)形成切口,从管的末端到平坦部分的一部分,使得通孔可以在切口的底部具有开口以能够与平坦部分接合 刹车片的腹板部分。
