摘要： Compression springs, such as helical compression springs, include end portions with selectively contoured inner contact surfaces. The selective contours of the inner contact surfaces may take the form of planar, grooved, concave, or other shaped, non-circular surfaces. In addition, enough of the inner contact surface is contoured to reduce the contact stress and/or stress concentration effects on the adjacent coils when the compression spring is placed under load and the adjacent coil engages or contacts the respective end portion. The selective contouring of the end portions may be accomplished by holding the spring in a holder and moving a cutter relative to the end portion of the spring to remove the desired amount of material from the end portion.
摘要翻译：诸如螺旋压缩弹簧的压缩弹簧包括具有选择性地形成轮廓的内接触表面的端部。内部接触表面的选择性轮廓可以采取平面，凹槽，凹形或其它形状的非圆形表面的形式。此外，当压缩弹簧被放置在负载下并且相邻的线圈接合或接触相应的端部部分时，足够的内部接触表面被轮廓化以减小对相邻线圈的接触应力和/或应力集中效应。端部的选择性轮廓可以通过将弹簧保持在保持器中并相对于弹簧的端部移动切割器以从端部移除所需量的材料来实现。

摘要： End mounts are used to secure a helical tension spring to end fixtures with various shapes and sizes. These end mounts contain an inner hole to encase the inner spring end mount and secure the end mount making it like a cap. There is also a keyhole created in the top surface that goes through the end mount allowing it to fit over the fixtures but not over the inner end mount, holding it in place. Grooves are machined in a helical pattern on the cylindrical side wall of the end mount. The spring is wound onto the grooves of the end mount.

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.
摘要翻译：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。

摘要： An improved torsion type rear suspension system for a snowmobile. The suspension includes a pair of rails movable with respect to the snowmobile body and a pair of torsion springs disposed between the body and the rails for biasing the suspension toward its extended position. Also included is a cam block having a contoured cam surface which engages a leg of the torsion spring at a variable point of contact. As the suspension moves from the extended to the collapsed position, the effective length of the spring leg is reduced, resulting in a nonlinear change in spring force as a function of deflection. The cam block may be adjusted with respect to the suspension rails with an eccentric to permit additional adjustment of the spring force function to compensate for varying terrain, vehicle speed, and operator weight.
摘要翻译：一种用于雪地车的改进的扭转型后悬架系统。该悬架包括一对相对于雪地运动体可移动的轨道，以及一对扭力弹簧，其设置在主体和轨道之间，用于将悬架偏压到其伸出位置。还包括具有轮廓凸轮表面的凸轮块，该凸轮表面以可变接触点接合扭转弹簧的腿部。当悬架从延伸位置移动到折叠位置时，弹簧腿的有效长度减小，导致作为偏转的函数的弹簧力的非线性变化。可以相对于具有偏心轮的悬挂轨道来调节凸轮块，以允许额外调整弹簧力函数以补偿变化的地形，车辆速度和操作者的重量。

摘要： Apparatus, systems, and methods for damping movement of a first mass relative to a second mass by magnetically generating induced current are provided. A magnet is coupled to one mass and a nonferrous metallic member is coupled to another mass that moves relative to the first mass. First and second springs are coupled to opposing ends of the magnet, the magnet being positioned between the springs. A guide member channels the magnet as it moves relative to the nonferrous member, the magnet being slidable along the guide member. The magnet is in close proximity to the nonferrous metallic member as the magnet moves. Upon causing movement of the magnet by either mass, the magnet generates an electrical current in the nonferrous metallic member that induces a counter magnetic field that opposes the magnetic field generated by the current to damp movement of the magnet as it moves.
