摘要：A suspension arrangement for a work machine includes a frame and a rear axle rigidly carried by and substantially immovable relative to the frame. The suspension arrangement includes a caster wheel assembly having a shaft, a wheel arm, a suspension and a caster wheel. The shaft is pivotably couplable with an outboard end of the rear axle. The caster wheel is coupled with a lower end of the wheel arm. The suspension is in the form of a torsion spring including an outer tube, an inner member, and a plurality of elastomeric members interposed between the outer tube and the inner member. The outer tube is coupled with the shaft, and the inner member is coupled with an upper end of the wheel arm.
