Endless spring, such as ringspring

摘要

An endless spring is an elastic body such as an oval or elongated or circular ring body for the transmission of loads in a main plane substantially centrally through the endless or ring body. Such a main plane extends in the plane of the drawing. The ring body is made up of a plurality of winding layers of fiber reinforced synthetic material. The windings in certain central body layers (2) preferably extend unidirectionally and the fibers in intermediate layers (3) and in outer layers extend at an angle relative to a main load application direction. The whole spring body includes a plurality of intermediate layers (3) and a plurality of outer layers (4) of synthetic resin impregnated fabric plies. The central body layers (2) form a winding body.
