Abstract
A spring with constant cross-sectional area for torsion and/or flexional strain is provided which includes a plurality of individual rods with a round or polygonal cross-section substantially identical to one another and unchanging over their length. In each case, the rods have line or surface contact with other rods and form a bundle held together at least at the ends of the rods. The rods can be round, hexagonal or isosceles triangular in cross-section, and the number of rods is 3n or 3n+1, whereby n is a natural number greater than or equal to 3. Alternatively, the rods can be octagonal or square in cross-section and the number of rods is 4n or 4n+1, whereby n is a natural number greater than or equal to 2.
Claims22
A torsion or flexion spring assembly having a uniform cross-sectional area comprising a plurality of individual rods each with a substantially identical cross-section unchanging along its length, and each having line or surface contact with at least two other rods, the plurality of rods forming at least a rod bundle held together at the ends, wherein each of the plurality of rods is round, hexagonal or isosceles triangular in cross-section and wherein the number of rods is 3n or 3n+1, whereby n is a natural number greater than or equal to 3.
A torsion or flexion spring assembly having a uniform cross-sectional area comprising a plurality of individual rods each with a substantially identical cross-section unchanging along its length, and each having line or surface contact with at least two other rods, the plurality of rods forming at least a rod bundle held together at the ends, wherein each of the plurality of rods is octagonal or square in cross-section and wherein the number of rods is 4n or 4n+1, whereby n is a natural number greater than or equal to 2.
