Abstract

A railcar coupler may include a coupler head including a shank (106) and a head (102) defining a pocket for receiving a knuckle knuckle (108), pusher (110) and lock (112). chamber (104). The chamber may include an upper pull lug (130a), a lower pull lug (130b) and a push iron stop (140). The upper pulling lug may be configured to engage the upper knuckle pulling lug (109a), and the lower pulling lug may be configured to engage the lower knuckle pulling lug (109b). During operation of the railcar coupler, the pressure ratio between the upper pulling lug and the lower pulling lug may be better balanced to help extend the life of the railcar coupler assembly.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to US Application No. 14 / 679,709, filed April 6, 2015, entitled "Railcar Coupler," which is incorporated herein by reference in its entirety. technical field [0003] The disclosure herein relates generally to the art of railcar couplers, and more specifically, to more uniform or balanced distribution of loads and pressures across railcar coupler bodies to increase the wear life of the coupler assemblies. Background technique [0004] A railcar coupler may be provided at each end of a railcar to allow each end of a railcar to be connected to the next end of an adjacent railcar. However, due to in-service loads, natural corrosion, and natural wear and tear after hundreds of thousands of miles on track, vehicle coupler assemblies and the elements that make up the assemblies wear and / or break in use over time and fracture. The main areas of wear and tear are the directly load-bea...
