Title:
プリロードされた２重スプリングアセンブリ
Document Type and Number:
Japanese Patent JP5793186
Kind Code:
B2
Abstract:
The present invention relates to dual-spring assembly that may be employed in cooperation with a damper unit to form a shock absorber. The spring rate of at least one of the springs is adjustable with a preload mechanism, which in turn is movable relative to the damper unit. Further, the dual-spring assembly includes two compression springs arranged in series and each having selected, but different spring rates. The first spring primarily absorbs the energy of applied loads that are below a first amplitude or threshold of applied load. Once the applied loads exceed the first amplitude of applied load, the dual-spring assembly operates with an effective spring rate to absorb the energy of applied loads that exceed the first amplitude of applied load. After a second spring of the dual-spring assembly achieves a desired amount of deflection, the first spring continues to absorb energy from the applied loads.
