Title:
SERIES AXLE SUSPENSION SYSTEM
Document Type and Number:
Japanese Patent JPS60143111
Kind Code:
A
Abstract:
A 4-spring, tandem axle suspension system comprising a pair of semi-elliptic compound leaf spring assemblies positioned on each side of the vehicle frame in fore-and-aft alignment. The remote ends of each pair of leaf springs are retained by engagement with front and rear brackets extending from the vehicle frame on each side, while the adjacent or proximate ends of the spring assemblies on each side are connected by means of a pair of shackles to opposing ends of an equalizer bar pivotally mounted on a bracket rigidly attached to the vehicle frame between the adjacent spring ends. Each inner or adjacent end of each spring assembly is pivotally attached to its shackles by means of a pivot bolt passing through a bushing and spring eye formed on the uppermost leaf of the spring assembly. A hook formed on the equalizer end of the second uppermost leaf of each multi-leaf spring assembly passes through an aperture provided in the adjacent shackle, and connects the shackle to the spring assembly in the event of failure of the spring eye or eye end of the main leaf, thereby preventing complete separation of each spring assembly from its shackle. This, in turn, prevents the freed end of the equalizer from damaging the adjacent torque rod in the case of the rear spring assembly, or prevents the broken section of the main spring leaf from damaging nearby chassis components such as air brake chambers in the case of the front spring assembly.
