摘要:
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.
摘要(中):
双弹簧组件技术领域本发明涉及双弹簧组件,其可与阻尼单元配合使用以形成减震器。 至少一个弹簧的弹簧刚度可以用预紧机构来调节,预紧机构又相对于阻尼器单元可移动。 此外,双弹簧组件包括串联布置的两个压缩弹簧,每个具有选择但不同的弹簧刚度。 第一弹簧主要吸收低于施加载荷的第一幅度或阈值的施加载荷的能量。 一旦施加的载荷超过施加的载荷的第一幅度,双弹簧组件以有效的弹簧速率运行,以吸收超过施加载荷的第一幅度的施加载荷的能量。 在双弹簧组件的第二弹簧实现期望的挠曲量之后,第一弹簧继续从施加的载荷吸收能量。
