MACHINE SUSPENSION SYSTEM HAVING TORSION AXLE ASSEMBLIES

摘要

A suspension system (12) for a machine (10) is disclosed. The suspension system may have a front torsion axle assembly (24) with a first arm (56) connected at a first end (56a) to a first shaft (54), and a first axle (58) connected to a second end (56b) of the first arm. The suspension system may also have a rear torsion axle assembly (26) with a second arm (56) connected at a first end (56a) to a second shaft (54), and a second axle (58) connected to a second end (56b) of the second arm. The suspension system may further have a frame (14) connected to an end of the first shaft and an end of the second shaft. The second ends of the first and second arms are oriented within common angular quadrants defined by a coordinate system having an axis passing through the first ends of the first and second arms and aligned with a travel direction of the machine.
