摘要： A slack adjuster for use with a railway braking system which has an increased let-out length that enables the use of brake shoes having an increased thickness. The slack adjuster includes at least one of a dual spring and canister assembly, an external yoke trigger, or a combination of both a dual spring and canister assembly and an external yoke trigger. A method of retrofitting a truck mounted brake system is provided, in which the slack adjuster is positioned within the brake system in order to increase the let-out length while maintaining a predetermined spatial envelope within the brake system. The slack adjuster has an increased let-out length enabling the use of thicker brake shoes without requiring modification of the interacting components of the truck mounted brake system since the overall size of the slack adjuster remains the same.

摘要： A drainage system for use with a slack adjuster for a railway brake rigging wherein the slack adjuster includes a main spring housing, a cone nut housing enclosing a critical operating area of the slack adjuster, and an over travel housing. The drainage system includes at least one opening extending through a sidewall portion of the main spring housing. The opening is configured to allow fluid and/or contaminates to drain therethrough to reduce exposure of the critical operating area of the slack adjuster to the fluid and/or contaminants. A seal/splash guard can be provided at the intersection of the main spring housing and the cone nut housing to prevent fluid and contaminants from entering into the cone nut housing.
摘要翻译：一种与用于铁路制动索具的松弛调节器一起使用的排水系统，其中所述松弛调节器包括主弹簧壳体，包围所述松弛调节器的关键操作区域的锥形螺母壳体和过度行驶壳体。排水系统包括延伸穿过主弹簧壳体的侧壁部分的至少一个开口。开口构造成允许流体和/或污染物从其中排出，以减少松弛调节器的临界操作区域暴露于流体和/或污染物。主弹簧壳体和锥形螺母壳体的交点处可以设置密封/防溅罩，以防止流体和污染物进入锥形螺母壳体。

摘要： A debris eradicating brake head for use in a side frame mounted braking system in a railway vehicle. The brake head being mounted on an end of a brake beam and including a brake shoe carrier associated with the brake head, a brake shoe secured to a face portion of the brake shoe carrier, and a brake head extension extending from a side portion of the brake shoe carrier for associating the brake head within a unit guide in a side frame of the railway vehicle. The brake head extension including at least one of a first and a second tapered surface configured for breaking up and pushing debris out of the unit guide in the side frame. Eradication of debris within the side frame increases the braking efficiency of the railway vehicle as it reduces the amount of force necessary for applying the brake shoes to the wheels.
摘要翻译：用于在铁路车辆中的侧架安装制动系统中使用的碎片消除制动头。制动头安装在制动梁的端部上，并且包括与制动头相关联的制动蹄支架，固定到制动蹄支架的面部的制动蹄以及从制动蹄的侧部延伸的制动头延伸部用于将制动头联接在铁路车辆的侧框架内的单元导向件内的制动蹄座。制动头延伸部包括第一锥形表面和第二锥形表面中的至少一个，所述第一锥形表面和第二锥形表面中的至少一个构造成用于在侧框架中将碎屑打碎并推出单元引导件。消除侧架内的碎屑增加了铁路车辆的制动效率，因为它减少了将制动蹄施加到车轮上所需的力量。

摘要： A vented cap for a main spring housing of a slack adjuster including an inner portion having an inner seal surface configured for cooperating with an elongated rod member and an outer seal surface configured for cooperating with a sidewall located at an end portion of the main spring housing. The vented end cap includes at least one opening configured to allow fluid and/or contaminants trapped within the slack adjuster and/or the end cap to drain therethrough. Various seals and/or drainage openings can also be provided along the slack adjuster to prevent the entrance of and/or allow for drainage of fluid/contaminants from the slack adjuster. A method for preventing the accumulation of fluid and/or contaminants within a slack adjuster and for protecting a critical operating area of the slack adjuster is also provided.
