ABSTRACT:
An auxiliary damper is provided for a passenger cab on heavy equipment or the like, the damper being contained within the confines of the primary suspension system and being secured to a first one of a supported element and a support to provide surface-effect damping as needed to damp high-amplitude, low-frequency vibration in the region of the resonant frequency of the primary suspension. An elastomeric sleeve is bonded to a rigid sleeve member which surrounds the securement bolt for the primary mount. A spool member with internal protrusions engagingly surrounds the elastomeric sleeve. The spool has upper and lower flanges which overlie and underlie, respectively, in non-engaged relationship, the second of a supported element and a support. When there is low-amplitude, high frequency motion of the support, this non-engaged relationship allows the supported element to be isolated from such motion. When the amplitude of the vibration becomes large enough as, for example, near resonance, the spool of the auxiliary damper engages its supported element or support and dissipates the vibrational energy as heat to effectively damp the large amplitude motion and maintain a comfortable ride.
