German koni springs koni models koni prices

koni spring is a new type of elastic component that uses high-pressure nitrogen as the working medium. It features compact size, high spring force, long stroke, smooth operation, precision manufacturing, long service life (one million cycles), flat force-deflection curve, and no need for preloading. It performs tasks difficult for conventional elastic components such as metal springs, rubber, and air cushions, simplifies mold design and manufacturing, facilitates mold installation and adjustment, extends mold service life, ensures stable product quality, and can be designed as a nitrogen spring system to operate as part of the mold, enabling constant pressure and delayed action within the system. It is an ideal new-generation elastic component with flexible performance.

koni spring features

1) High stiffness, strong buffering and vibration absorption capacity, capable of bearing heavy loads with small deformation, suitable for applications with limited axial space. 2) Variable stiffness characteristics, offering a wide range of nonlinear properties. 3) Using the same disc springs in different combinations allows significant variation in spring characteristics. Combinations can be arranged in face-to-face or stacked configurations, or by combining different thicknesses and numbers of discs. 4) In stacked arrangements, for the same deformation, the load increases with the number of springs. 5) Short stroke, heavy load, small space requirement, convenient combination, easy maintenance and replacement, economical, high safety, and long service life.

koni spring features

1) Precise adjustment performance, meaning the relationship between force and displacement is highly sensitive; 2) Good flexibility, meaning a relatively wide range of deformation; 3) Relatively easy manufacturing; 4) Compact structure; 5) High energy efficiency. Example characteristics: Conical helical springs offer good buffering performance and can bear large loads. Spiral torsion springs can store more energy and bear larger loads, but the manufacturing process is more complex. The performance of concave helical springs is similar to that of conical helical springs, often used in seat cushions and mattresses. Spring wire cross-sections include circular and rectangular, with circular being the most common. Helical springs, also known as torsion springs, undergo torsional deformation, with their working part tightly wound into a spiral shape. The ends of torsion springs are processed into various shapes of torque arms rather than hooks. Torsion springs are commonly used in balancing mechanisms in machinery and are widely applied in automotive, machine tool, and electrical industries.

Suspensions using torsion bar springs have lighter mass, simpler structure, and require no lubrication. By adjusting the installation angle of the fixed end of the torsion bar spring, automatic vehicle height adjustment is easily achieved. Torsion bar springs store greater elastic energy per unit volume and have low mass. Compared to helical springs, torsion bar springs are compact and easier to arrange. They are widely used in off-road vehicles, light passenger cars, and trucks. Torsion bar springs are classified by cross-sectional shape into circular, tubular, and leaf types. Solid circular torsion bars have a simple structure and are the most commonly used. To facilitate assembly, both ends are machined with splines, hexagonal, square, or other shapes. Due to the smaller size of spline ends, spline connections are predominantly used. Generally, the major diameter of the spline is 1.2 to 1.3 times the working diameter of the torsion bar, and the spline length is approximately 1.4 times the major diameter of the spline. As long as the compressive stress on the spline teeth is within permissible limits, the spline teeth should not be excessively long. Torsion bar springs generally use involute splines according to GB3478. The JSB2705 standard recommends a standard pressure angle of 45° for splines, with modules of 1mm and 0.75mm. To facilitate assembly, some torsion bar springs have unequal diameters at both ends or a blind tooth machined on the spline teeth at both ends.
