Abstract (en)
[origin: EP0841452A2] The mechanism comprises a straight or curved spring bar (51) which is subjected to compression, tension and-or torsional load. The bar is mounted between two supporting components (5a,5b). There can be several roughly parallel bars, preferably inclined to a common central axis, and so arranged that the sum of the radial forces in relation to this axis acting on the supporting components is minimal and preferably zero. The bars can be mounted symmetrically in relation to the axis. They can be inclined to each other, and of different thicknesses and-or lengths. They can be at different radii from the component centres.
