A steering assembly includes a piston rod including internal threads positioned on an inner wall of a recess, an inner tie rod housing including external threads engaging with the internal threads, the inner tie rod housing adjustably connected to the piston rod, a tie rod including an inner tie rod having an end positioned at least partially in the inner tie rod housing, a retainer including a wall portion and a flange portion, the retainer positioned at least partially in the recess, the retainer including a protrusion extending from an outer surface of the wall portion and contacting the inner wall of the recess, which resists rotation of the retainer, and one or more fasteners releasably attaching the retainer to the inner tie rod housing.

Steering assembly

A work vehicle includes a frame, an axle, a cab supported by the frame, a first tuned mass damper assembly, and a second tuned mass damper assembly. The frame includes a first longitudinal frame member and a second longitudinal frame member. The first longitudinal frame member has a first rear end, and the second longitudinal frame member has a second rear end. The second longitudinal frame member extends parallel to the first longitudinal frame member. The axle extends perpendicular to the first and second longitudinal frame members. The cab is disposed on a side of the first and second longitudinal frame members opposite the axle. The first tuned mass damper assembly is mounted on the first longitudinal frame member between the first rear end and the cab. The second tuned mass damper is mounted on the second longitudinal frame member between the second rear end and the cab.

Work vehicle with tuned mass dampers

An operator station suspension system including a subframe structure with connection locations, isolators, and suspension components to couple the subframe structure to a chassis and enable movement of the subframe structure relative to the chassis. The subframe structure connects to an operator station at the connection locations with isolators between the subframe structure and operator station at each connection location to reduce noise and vibration. The isolators can be made of rubber, polymer or other materials. Each connection location can have a connection post, and the isolators can be ring-shaped to fit over the connection posts. The suspension components can include shock dampers that enable vertical movement, control linkages that enable pitch motion, and/or stabilizer linkages that enable roll motion of the subframe structure relative to the chassis. The subframe structure can include a rigid body with forward and rearward arms rigidly connected to the rigid body.

Operator station suspension isolation system

An operator station suspension system including isolators, a butterfly crossbar and station connection locations located on the butterfly crossbar. The butterfly crossbar includes a central crossbar that extends laterally with forward extending arms rigidly connected at the left and right ends, and rearward extending arms rigidly connected at the left and right ends of the central crossbar. The butterfly crossbar couples to the operator station at the station connection locations with one of the isolators located between the butterfly crossbar and the operator station at each of the station connection locations to reduce noise and vibration. Each connection location can have a connection post, and the isolators can be ring-shaped to fit over the connection posts. The suspension system can also include shock dampers for vertical movement, control linkages for pitch motion, and/or stabilizer linkages for roll motion of the subframe structure relative to the chassis.
