Embodiment Construction

[0013] figure 1 A perspective view of a coupler frame according to certain embodiments is shown. The coupler frame 100 includes a butt end 101 (butt end) and a nose end 102 connected to each other by a frame plate 150 . The shape and features of coupler frame 100 can help reduce bending stresses at various locations of coupler frame 100 (eg, where frame plate 150 connects to tail end 101 and nose end 102 ), while also The weight of the coupler frame 100 is reduced.

[0014] The coupler box 100 may increase life and reduce weight compared to conventional coupler boxes, such as conventional E-type coupler box. This can be achieved by including new openings and coves as well as increasing the size / radius of some coves. For example, in the depicted embodiment, coupler frame 100 includes openings 180 and 120 and 110 , 130 , 160 and 170 . These features can be included on coupler boxes that meet certain coupler standards. For example, coupler box 100 may be used in place of a c...

Abstract

A railway car yoke (100) includes a nose end (102) and at least two straps (150) adjoining the nose end (102). At least one top strap (150B) adjoins a top portion of the nose end (102) and at least one bottom strap (150A) adjoins a bottom portion of the nose end (102). The railway car yoke (100) also includes a butt end (101) adjoining the at least two straps (150) such that the nose end (102) and the butt end (101) are separated by the at least two straps (150). The butt end (101) comprises at least one concave contour (110) along an outside surface of the butt end (101). The outside surface is a surface along the butt end (101) opposite the nose end (102) that extends from a top surface of the at least one top strap (150B) to a bottom surface of the at least one bottom strap (150A).

Description

technical field [0001] The present disclosure relates to railway car connections, and more particularly to railway car yokes. Background technique [0002] The railroad car coupler is used to form a housing for the bumper and maintain the bumper proximate to the rear end of the connector so that forces applied to the head of the connector are damped by the bumper. In a standard freight vehicle towing layout, a rectangular steel block is inserted between the butt of the connector shank and the front working end of the buffer. The steel block extends transversely across the front end of the coupler frame bumper receiver and is referred to as the front plate. The relative position of the front plate and bumper to the connector tail is maintained as the coupler frame is secured to the connector shank by a connecting key or pin. [0003] The premise of the hooktail frame design is the bumper and the connector shank end. The buffer receiving portion of the coupler frame is comp...
