Arrangement for transferring torsion torque, particularly in the form of a torsion spring or drive shaft made of composite fiber materials in order to achieve a high specific material usage

Abstract

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.
