German wiedenhoefer springs wiedenhoefer models wiedenhoefer prices

wiedenhoefer springs are elastic elements with multiple peaks and valleys on a thin metal ring. They are typically used in applications where the load and deformation are small, requiring low spring stiffness and the application of axial preload. Wave springs are particularly suitable for weight-sensitive applications and those constrained by limited installation space. Typical application areas include aerospace, precision machinery, hydraulic seals, and high-end motors. This product is a thin, ring-shaped elastic metal element composed of multiple peaks and valleys. It is made from high-quality spring steel 65Mn (60Si2MnA/50CrVA /0Cr17Ni7Al /SUS304), heat-treated using specific methods. Depending on specific conditions, the hardness is generally controlled between HRC44 and 55. The surface is blackened, providing good elasticity. Wave springs are widely used in industries such as motors, textile machinery, hydraulic equipment, and automotive. They are mainly installed in bearing housings or bores suitable for their nominal dimensions. With minimal installation space, they offer special functions such as noise reduction and vibration damping.

wiedenhoefer spring features

1) High stiffness, strong buffering and vibration absorption capability, capable of withstanding large loads with small deformation, suitable for applications with limited axial space. 2) Features variable stiffness characteristics; this type of spring has a wide range of nonlinear characteristics. 3) Using the same disc springs in different combinations can significantly vary the spring characteristics. Combinations can be arranged in opposing or stacked configurations, or by combining different thicknesses and numbers of discs. 4) When stacked, for the same deformation, the more springs used, the greater the load. 5) Short stroke, heavy load, small space requirement, convenient combination, easy maintenance and replacement, economical, high safety, and long service life.

wiedenhoefer spring structure and principle

A torsion bar spring is itself a torsion bar made of spring steel. The cross-section of the torsion bar is usually circular, with a few being tubular or rectangular. The ends can be shaped as splines, square, hexagonal, or cylindrical with flat surfaces, allowing one end to be fixed to the vehicle frame and the other to the suspension arm, which is connected to the wheel. One end of the torsion bar spring is fixed to the vehicle frame, and the other end is connected to the wheel via the suspension arm. When the wheel encounters an obstacle on the ground and jumps upward, the wheel drives the suspension arm to rotate around the torsion bar axis by a certain angle, causing the torsion bar to undergo torsional deformation (elastic deformation). Meanwhile, the elastic potential energy stored in the torsional deformation of the torsion bar is released when the wheel leaves the obstacle, allowing the force transmission mechanism and the wheel to return to their original positions quickly. During the manufacturing of torsion bar springs, the torsion bar is pre-twisted to create a permanent torsional deformation, imparting a certain level of prestress. The direction of the applied pre-torsion is the same as the direction of torsion when the torsion bar operates on the vehicle, aiming to reduce the actual stress during operation and extend service life. Note that left and right torsion bars are not interchangeable.

wiedenhoefer spring features and applications

Features: Compared to ordinary compression or extension springs, its spring force is very constant, outputting a nearly linear force, ensuring that the product does not change due to variations in spring force during use. In narrow and elongated spaces, it can minimize space usage as much as possible, enhancing possibilities for aesthetic product design. Constant force spring applications: lift fans, LCD monitors, sliding windows and doors, supermarket automatic checkout counters, motor carbon brush pressure devices, cables, stapler springs, power tools, car ashtrays, locomotive carbon brush accessories, medical devices, mobile phone holders, etc.
