Abstract
A cab suspension system for coupling a cab frame to a chassis frame of a work vehicle is disclosed. The chassis frame may include a suspension platform. The suspension system may generally include a pad configured to be coupled to the cab frame and an outer tube extending from the pad in a direction of the suspension platform. The outer tube may define a circumference. Additionally, the suspension system may include a bump stop coupled to the outer tube. The bump stop may extend around a portion of the circumference of the outer tube. Moreover, at least a portion the bump stop may extend below the outer tube such that the bump stop is configured to contact the suspension platform prior to the outer tube when the outer tube is moved in the direction of the suspension platform.
