SILENCER FOR A MULTI-LEAF SPRING

Title:

SILENCER FOR A MULTI-LEAF SPRING

Document Type and Number:

WIPO Patent Application WO/2012/014635

Kind Code:

A1

Abstract:

Disclosed is a silencer for a multi-leaf spring whereby both the strength of a protruding part is increased and anomalous noises are prevented, and a component count is reduced due to structural simplification and increased ease of manufacture. Said silencer (1), which is disposed between the ends of leaf springs (101 and 102) in a multi-leaf spring (100), has a two-layer structure comprising a fixed layer (11) and a sliding layer (21) formed as a single unit. The fixed layer (11) has a protruding part (12) with an engagement part (13) formed in the tip thereof. The fixed layer (11), which is affixed to a fixed-side leaf spring (101), has a higher tensile strength than the sliding layer (21). The sliding layer (21), which abuts against a sliding-side leaf spring (102), is harder than the fixed layer (11). The protruding part (12) of the fixed layer (11) can exhibit sufficient strength with respect to shear forces. The sliding layer (21) is not prone to anomalous noises and can even minimize anomalous noises when a load-transmission part of the end of the sliding-side leaf spring (102) makes off-center contact.
