German schweizer springs schweizer models schweizer prices

schweizer springs are conical disc-shaped. They can be used individually or in series or parallel combinations. They withstand static or dynamic axial loads at the upper inner edge and lower outer edge, deforming under compression until flattened to store energy as a live load. When necessary, they automatically convert into additional compressive load required for sealing, reducing the continuous tightening requirements for gaskets and packing. Disc springs are special springs that are conical in the axial direction and bear loads. After deforming under load, they store potential energy. When bolts loosen, the disc spring releases part of the potential energy to maintain pressure between flange connections to meet sealing requirements. The stress distribution of disc springs decreases uniformly from the inside out, achieving high compensation force with low travel. schweizer springs

schweizer spring features

1) High stiffness, strong buffering and vibration absorption capability, capable of bearing large loads with small deformation, suitable for applications with limited axial space. 2) Variable stiffness characteristics; these springs have a wide range of nonlinear properties. 3) Using the same disc springs in different combination methods allows spring characteristics to vary widely. Combination methods such as face-to-face or stacked arrangements can be adopted, as well as combinations with different thicknesses and numbers of discs. 4) When stacked, for the same deformation, the more springs there are, the greater the load. 5) Short travel, heavy load, small space requirement, convenient combination, easy maintenance and replacement, economical, high safety, long service life.

schweizer spring advantages and classification

The advantages of leaf springs are simple structure, reliable operation, low cost, and easy maintenance. They serve as both the elastic element of the suspension and the guiding device. One end is hinged to the frame, allowing it to transmit various forces and torques and determine the wheel's runout trajectory. At the same time, it provides a certain degree of frictional damping. Achieving three benefits at once, it is widely used in non-independent suspensions. Leaf springs are classified by shape: 1) elliptical leaf spring; 2) semi-elliptical leaf spring; 3) quarter-elliptical leaf spring; 4) single-leaf spring. Elliptical, semi-elliptical, and quarter-elliptical leaf springs are all composite types of leaf springs, relying on the friction between the leaves to provide high buffering and vibration damping performance, and are widely used in the suspension systems of automobiles, tractors, and railway vehicles; single-leaf springs are made of single-piece spring steel and are mostly used in mechanical equipment and instruments to press working components.

Suspensions using torsion bar springs are lighter in weight, simpler in structure, and do not require lubrication. By adjusting the installation angle of the fixed end of the torsion bar spring, automatic adjustment of vehicle height is easily achieved. Torsion bar springs store greater elastic energy per unit volume and have low mass. Compared with coil springs, torsion bar springs are compact and easy to arrange. Torsion bar springs are commonly used in off-road vehicles, light passenger cars, and trucks. Torsion bar springs can be classified by cross-sectional shape into circular, tubular, and flat types. Circular solid torsion bars have a simple structure and are most commonly used. To assemble the torsion bar, both ends are machined with splines, hexagonal, square, etc. shapes. Due to the smaller size of the spline ends, spline connections are mostly used. Generally, the major diameter of the spline is 1.2~1.3 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 crushing stress of the spline teeth is within permissible limits, the spline teeth should not be too long. Torsion bar springs generally use involute splines GB3478. In the JSB2705 standard, the recommended standard pressure angle for splines is 45°; modules are 1mm and 0.75mm. To facilitate assembly of torsion bar springs, some have unequal diameters for the splines at both ends or process a blind tooth on the spline teeth at both ends.
