    • The invention is directed to an insert for a backing plate assembly for a composition friction brake shoe. The insert is particularly useful in the formation of a universal brake shoe for use with a trolley car braking system. The insert includes a central member having a first and second set of attachment posts extending from the respective ends thereof. These first and second sets of attachment posts are adapted for securing a first and second backing plate strap, respectively, thereto. A key bridge extends through a back portion of the central member and is configured for attachment to a brake shoe. A flange guide support extends from a side portion of the insert and includes legs defining a channel that runs parallel to the insert. The flange guide support is adapted for contacting a wheel flange to align a brake shoe with the wheel during braking of the vehicle.
    • 本发明涉及用于组合摩擦制动蹄的背板组件的插入件。 插入件特别适用于形成用于手推车制动系统的通用制动蹄。 插入件包括具有从其相应端部延伸的第一和第二组附接柱的中心构件。 这些第一组和第二组附接柱分别用于固定第一和第二背板带。 钥匙桥延伸穿过中心构件的后部,并且构造成用于附接到制动蹄。 凸缘引导支撑件从插入件的侧部延伸,并且包括限定平行于插入件延伸的通道的支脚。 凸缘引导支撑件适于在车辆制动期间接触车轮凸缘以使制动蹄与车轮对准。

    • The brake shoe support assembly is able to track the lateral movement of a wheel, typically a wheel on an axle truck that allows lateral wheel movement. In operation, a flange of the wheel pushes on one side of the brake shoe support assembly, pushing it along a pin, and compressing a resilient biasing structure. As the wheel returns to a center or neutral position, the compressed resilient biasing structure expands pushing the brake shoe support assembly back to an original or neutral position. The resilient biasing structure also minimizes the lateral movement of the brake shoe support assembly down the wheel taper under normal braking loads thus preventing shoe ride-off. The resilient biasing structure may be enclosed in a housing adapted to prevent the intrusion of contaminants.
    • 制动蹄支撑组件能够跟踪车轮的横向运动,车轮通常是允许横向轮移动的车轴上的车轮。 在操作中,轮的凸缘推动制动瓦支撑组件的一侧,沿着销推动其,并且压缩弹性偏置结构。 当轮回到中心位置或中间位置时,压缩的弹性偏置结构将制动蹄支撑组件推回到原始或中立位置。 弹性偏置结构还使得制动瓦支撑组件在正常制动负载下沿着车轮锥度的横向移动最小化,从而防止滑行。 弹性偏压结构可以封闭在适于防止污染物侵入的壳体中。
