Independent Front Suspension with Pitch Control for Track-Type Tractor

摘要

A front suspension system for a track-type tractor includes a suspension saddle having first and second suspension arms pinned to the suspension saddle, the first and second suspension arms being connected to the machine tracks via first and second front idler respectively. Respective first and second hydraulic suspension assemblies support the first and second suspension arms, and a hydraulic suspension circuit fluidly links the first hydraulic suspension assembly to the second hydraulic suspension assembly such that a movement of either the first or the second hydraulic suspension assemblies causes an opposite movement of substantially the same magnitude in the other of the first and second hydraulic suspension assemblies, thereby allowing the first track and the second track of the track-type tractor to oscillate relative to one another.
