Abstract

A chassis suspension for agricultural equipment, the chassis suspension comprising: an axle having a substantially upright journal adapted for upright axial constraint of an inner journal therein; an inner journal extending into the upright journal, the inner journal having a lower end, wherein the inner journal is adapted to constrain axial movement of a strut rod therein; a strut rod extending into the inner journal and having a lower strut rod portion adapted for mounting a ground-engaging drive mechanism and wheel, wherein the lower strut rod portion has an upper end; and, a spring constrained between the lower end of the inner journal and the upper end of the lower strut rod portion.

Claims

1. A chassis suspension comprising:

an axle having a substantially upright journal adapted for upright axial constraint of an inner journal therein;

an inner journal extending into the upright journal, the inner journal having a lower end, wherein the inner journal is adapted to constrain axial movement of a strut rod therein;

a strut rod extending into the inner journal and having a lower strut rod portion adapted for mounting a ground-engaging drive mechanism and wheel, wherein the lower strut rod portion has an upper end; and

,

a spring constrained between the lower end of the inner journal and the upper end of the lower strut rod portion.

2. The suspension of claim 1, wherein the upright journal is further adapted for rotational movement of the inner journal therein and the inner journal is further adapted for rotational movement of the strut rod therein.
