Multi-Wire Springs

Multi-wire springs are made of wire strands with various strand structures and are put to use as compression, torsion, tension and form springs.

From a technical point of view, Roehrs multi-wire springs are highly sophisticated products and are used in case single-wire springs made of round, flat or square wire could fail due to highly dynamic frequencies and high-impulse stresses or could not guarantee the operational safety. Due to the strand structure, multi-wire springs display increased spring loads and reduced torsion stresses at high deflections compared to single-wire springs.

The tensile stresses in the cross-section of the wire significantly counteract the torsion stresses which would normally destroy the spring and lead to an increased damping effect.

The essential advantages at a glance:

• Absorption of high impact velocities and peak loads
• Absorption of high dynamic frequencies
• Excellent damping features
• Optimization of damping and gliding features as well as durability by means of thermoplastic coating
• Optimum utilization of material in the cross section of the wire strand by converting torsion into tensile stresses
• High operational safety, as the spring force is virtually unaffected by breakages within the strand
• High deflections possible, even given small outer diameters
• Flat spring characteristic, increasing progressively when close to solid length
