US 12,403,965 B2 · Multi-member frame assembly for a track system

Abstract

A multi-member frame assembly for a track system includes a pivot pin defining a pivot axis, a leading frame member pivotally connected to the pivot pin for pivoting about the pivot axis, and a trailing frame member pivotally connected to the pivot pin for pivoting about the pivot axis, the trailing frame member pivoting independently from the leading frame member. A resilient member is pivotally connected to the leading frame member and to the trailing frame member. The resilient member extends generally vertically between the leading frame member and the trailing frame member. A track system having a multi-member frame assembly is also described.
