摘要： 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.

摘要： Disclosed is an end stabilized backing plate for an extended length brake shoe for use in a railway braking system. The backing plate includes an elongated main portion extending along a longitudinal axis. This main portion has a front face, a back face, a first end portion and an opposed second end portion. A first and second pair of tab members are provided on each of the first and second end portions. These tab members extend in a substantially perpendicular direction with respect to the main body and function to stabilize the end portions of the extended length brake shoe which extend beyond the length of a brake head and reduce and/or eliminate cracking of these end portions of the brake shoe. A method of stabilizing end portions of an extended length brake shoe is also disclosed.
摘要翻译：公开了用于在铁路制动系统中使用的延长长度制动瓦的端部稳定的背板。背板包括沿着纵向轴线延伸的细长主体部分。该主要部分具有前表面，后表面，第一端部和相对的第二端部。第一和第二对突片构件设置在第一和第二端部中的每一个上。这些翼片构件相对于主体沿基本垂直的方向延伸，并且用于使延伸长度制动蹄的端部延伸超过制动头的长度，并且减小和/或消除这些端部的开裂制动蹄片。还公开了一种稳定延长长度的制动蹄的端部的方法。

摘要： A brake shoe without a metal backing has a metal insert comprising two spaced apart bodies (10,11), a connecting portion (13) having a back face adjacent to the back surface of the brake shoe, and two generally parallel radially-extending flanges (15) integral with the connecting portion. The parallel radially extending flanges (15) define a keyway, wherein when the brake shoe is emplaced on the brake head, the keyway extends through an opening provided in the brake head.

摘要： A brake shoe formed of friction material for use without a metal backing plate. The brake shoe is defined by a friction surface (10) for bearing upon a wheel tread and an opposed back surface (12) for being placed in- contact with and secured to a brake head. The brake shoe has a reinforcing mesh (20)' defining a plurality of interstices positioned along the back surface of the brake shoe embedded in a molded friction material that is reinforced with a plurality of fibers. A keyway (1) is at least partially formed of the molded fiber reinforced friction material extending away from the back surface of the brake shoe.
摘要翻译：由不含金属背板的摩擦材料形成的刹车片。制动蹄由用于承载在轮辋上的摩擦表面（10）和相对的后表面（12）限定，用于与制动头接触并固定。制动蹄具有限定沿着制动蹄的后表面定位的多个间隙的增强网（20），所述多个间隙被嵌入在用多个纤维增强的模制摩擦材料中。键槽（1）至少部分地由延伸离开制动蹄背面的模制纤维增强摩擦材料形成。

摘要： A brake shoe without a metal backing has a metal insert (9) comprising a main body (10), two wing-like extensions (12/13) integral with, on opposite sides of and extending away from the main body having back faces adjacent to the back surface of the brake shoe, two generally parallel radially extending flanges (15/16) integral with the main body and/or the wing-like extensions. The parallel extension defines a keyway (17), wherein when the brake shoe is emplaced on the brake head, the keyway extends through an opening provided in the brake head.
