    Abstract: A polymer spring has a hollow tubular polymer body, wherein the first end portion of the body, the second end portion of the body, and the mid-portion of the body together substantially maintain an annular cylindrical column structure throughout the length of the body from the first end portion of the body to the second end portion of the body, such that the mid-portion of the body has a substantial portion that is in direct alignment with the first end portion of the body and the second end portion of the body when the spring is compressed to eliminate or reduce the chances of the spring failing caused by the spring folding or buckling and to reduce material fatigue in the polymer spring associated with folding or buckling.

  • Publication number: 20140131931
    Abstract: The spring device includes a part using the resilient properties of the material from which the part is made. There are at least two opposite points or areas, which are to be biased. The device includes, between the points or areas, an intermediate portion including a mesh structure resulting from the assembly of optionally rectilinear segments, at least two of which lie in separate planes, both outside of the direction of bias. During the biasing, one segment is longitudinally biased by compression and the other is longitudinally biased by pulling.

  • Patent number: 8720084
    Abstract: Impact attenuating/spring systems may include first and second body portions and at least one spring member at least partially included between the body portions. The spring member(s) may substantially enclose and/or be pivotally engaged with the body portion(s). The components of the impact attenuating and spring element may be arranged such that when a force is applied to the body portion(s), the spring member(s) will exert a counter force to urge the impact attenuating and spring element back toward its original orientation. The spring members may include one or more polymeric element that stretches under a tensile force. The impact attenuating and spring elements may be included in a piece of footwear or other device in a manner such that a user or a retailer (or others) can select an appropriate spring member (or portion thereof), e.g., depending on characteristics of the user or the intended use.

  • Patent number: 8720921
    Abstract: A vehicular suspension enhancer comprises a pair of vertically oriented spring portions, one portion mounted to the axle and the other portion mounted to the frame. Each vehicle axle can be equipped with two suspension enhancers, one enhancer located on each side of an axle. Each of the spring portions are positioned in the space between the axle and the vehicular frame, with the distal ends of each spring portion facing one another with a space between the distal ends defining a gap. The gap between the facing spring portions will increase in response to an increase in the distance between frame and axle.

  • Publication number: 20140117601
    Abstract: A spring functional component for a hydroelastic bearing. The component comprises a mounting inner connection, a mounting outer connection radially surrounding the mounting inner connection, a spring body which delimits at least two working chambers for receiving a damping fluid and couples the mounting inner and outer connections to one another in order to allow a relative movability between the mounting inner and outer connection and a support frame surrounding the mounting inner connection made of a rigid material such as plastic or metal, on which at least one radial stop is held, wherein the radial stop can be displaced from a pre-assembly state, in which a stop end of the radial stop is disengaged with respect to a stop counterpiece on the mounting inner connection side or mounting outer connection side, into a final assembly state in which the stop end engages the stop counterpiece.

  • Patent number: 8701290
    Abstract: A method of making a compressible elastomeric spring including at least one compressible elastomeric pad enclosed by a pair of metal plates includes the steps of forming plates with a center aperture and a plurality of prongs positioned about a peripheral edge thereof, forming each end of the pad with an axial projection and abutting groove, aligning the plurality of prongs with each respective projection and respective groove and applying axial force to one end of the spring to frictionally interlock the plurality of prongs with such projection and groove. The method also provides for making a multi-tiered stack of pads separated by plates in the above described manner and pre-shortening the spring prior to installation into the conventional yoke. The above described method additionally improves axial straightness and lateral stability of the multi-tiered spring assembly.

  • Publication number: 20140097293
    Abstract: A landing gear strut incorporating an oleo-pneumatic shock absorber with a bungee return spring. An oleo-pneumatic shock absorber is a device engineered for slowing down a moving mass. The shock absorber converts the kinetic energy of the impact into heat due to the friction of oil being driven through narrow orifices. The shock then recovers using air and or spring pressure. The recovery is governed by the flow rate of the fluid to the original reservoir. In the case of an aircraft this results in less bounce, shorter stop time, smoother overall ride, and safer landings.

  • Patent number: 8646761
    Abstract: An elastomeric isolator has an elastomeric body which incorporates an inner structural member and an outer structural member. The elastomeric body includes a shear hub extending between radial flanges defined by the inner and outer structural members that undergo shearing stresses during deflection of the elastomeric isolator. The inner and outer structural members are designed to provide a travel stop for the elastomeric isolator in order to avoid compression of the shear hub during high loads. The elastomeric bushing can also include an optional integral elastomeric heat shield which protects the shear hub.
