Estimating the term…
The invention relates to a torsion carrier, particularly a torsion spring, helical spring, drive shaft or balance shaft, which enables significant material and installation space savings compared to the prior art. The torsion carrier consists of a plurality of, but at least two supporting layers lying radially one above the other, each of which consists of at least one spiral coil (1, 3), but preferably of a plurality of spiral coils made of predominantly unidirectional composite fiber material, wherein at least two of the supporting layers have a counterrotating spiral coil orientation relative to one other. An elastic intermediate spacer layer (2) is arranged between adjacent spiral coil layers, by means of which a decoupling of the spiral coil expansions of adjacent spiral coil layers is achieved. This achieves particularly favorable, predominantly single-axis states of stress which allow for a high level of material utilization.
A torsion carrier having at least two layers, each layer of the at least two layers including at least one spiral coil made of composite fiber material, wherein the at least two layers have a mutually opposed spiral coil direction of rotation and at least one spacing elastic intermediate layer arranged between the at least two layers, wherein at least one layer of the at least two layers includes at least two discrete spiral coils separated by a gap and disposed in parallel relationship, wherein the at least one spiral coil of a first layer of the at least two layers has a first surface in contact with the elastic intermediate layer and the at least one spiral coil of a second layer of the at least two layers has a second surface in contact with the elastic intermediate layer, and wherein the first surface and the second surface are disposed in parallel relationship with one another.
