Abstract
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.
