Title:
METHOD AND APPARATUS FOR ABSORBING RESONANCE VIBRATION IN LEAF SPRING IN SUSPENSION SYSTEM
Document Type and Number:
Japanese Patent JP2959958
Kind Code:
B2
Abstract:
PURPOSE: To improve ride comfort by designing a suspension system for isolating the transmission of road vibration from the unsprung portion of an automobile to the sprung portion of the automobile to be constructed of isolating devices each having an open span susceptible to resonance vibration and a damping device for attenuating the resonance vibration of the open span.
CONSTITUTION: A suspension system 22 provided for insulating the transmission of road vibration from the unsprung portion of an automobile 10 to the sprung portion 24 of the automobile 10 comprises a plurality of leaf springs 28, and in this case the suspension system 22 is further provided with a plurality of dampers 44 for progressive damping of movement of a drive axle 18 with respect to the frame 26 of the automobile 10. An induced resonance vibration damper 48 having first and second end portions 50, 52 is provided for damping resonance vibration induced in the leaf springs 28, and the second end portion 52 of the damper 48 is connected to a leaf spring damper clamp 49 located on the open span 46 of each leaf spring 28, so that the damper 48 attenuates the resonance vibration of the open span 46 of each leaf spring 28.
