摘要： A draft gear assembly having a variable angle friction clutch mechanism is provided. Such assembly includes a housing member having a compressible cushioning element disposed adjacent a closed end thereof. A seat is disposed between one end of the compressible cushioning element and an open end of the housing member. A friction cushioning assembly is positioned at least partially within the open end of the housing member and includes a plurality of friction surfaces disposed on a plurality of friction elements with at least one wedge member being engageable with the plurality of friction surfaces. At least one resilient member is provided to enable the friction cushioning mechanism to exhibit a variable angle. Such resilient member is engageable with at least one of the friction elements and exerts a lateral force on the friction cushioning mechanism which is at least sufficient to maintain all of the friction surfaces in frictional engagement during the useful life of the draft gear assembly.
