German huefra springs huefra models huefra prices

huefra springs are helical springs that withstand axial compressive forces. The cross-section of the material used is mostly circular, but rectangular sections and multi-strand steel wires are also used. The springs generally have equal pitch. Shapes of compression springs include: cylindrical, conical, convex, concave, and a small number of non-circular shapes. There is a certain gap between the coils of the compression spring. When subjected to external loads, the spring contracts and deforms, storing strain energy. Compression springs provide resistance to external compressive loads. Compression springs use multiple open coils to provide resistance to external pressure (such as gravity pressing down on wheels, or body weight pressing on a mattress). That is, they push back to resist external pressure. Compression springs are generally wound with metal wire at equal pitch and have a fixed wire diameter. In addition, there are conical compression springs, or springs combining conical and straight sections. Depending on the application area, compression springs can be used to resist pressure and/or store energy. Round wire is the most commonly used for compression springs, but compression springs are also made from square, rectangular, and specially shaped wire.

huefra spring features

1) High stiffness, strong buffering and vibration absorption capacity, capable of withstanding large loads with small deformation, suitable for applications with limited axial space. 2) Features variable stiffness characteristics, offering a wide range of non-linear properties. 3) Using the same disc springs in different combinations allows spring characteristics to vary over a wide range. Combination methods such as face-to-face and stacked arrangements can be adopted, as well as combinations with different thicknesses and numbers of discs. 4) When stacked, for the same deformation, the greater the number of springs, the higher the load. 5) Short stroke, heavy load, small space requirement, convenient combination, easy maintenance and replacement, economical, high safety, and long service life.

huefra spring classification

1) Torsion springs are springs that withstand torsional deformation. Their working part is also tightly wound into a helical shape. The end structure of torsion springs is processed into various shapes of torque arms, rather than hooks. Torsion springs utilize the lever principle, twisting or rotating elastic materials with softness and high toughness to generate significant mechanical energy. 2) Extension springs are helical springs that withstand axial tensile forces. When not under load, the coils of extension springs are generally close-wound with no gap. 3) Compression springs are helical springs that withstand axial compressive forces. The cross-section of the material used is mostly circular, but rectangular sections and multi-strand steel wires are also used. The springs generally have equal pitch. Shapes of compression springs include: cylindrical, conical, convex, concave, and a small number of non-circular shapes. There is a certain gap between the coils of the compression spring. When subjected to external loads, the spring contracts and deforms, storing strain energy. 4) Progressive springs adopt a design with inconsistent wire thickness and coil spacing. The advantage is that when the pressure is low, the section with a lower spring rate absorbs road undulations, ensuring riding comfort. When the pressure increases to a certain level, the thicker section of the spring supports the vehicle body. The disadvantage of this type of spring is that the handling feel is not direct, and precision is poorer. 5) Linear springs have consistent wire thickness and coil spacing from top to bottom, with a fixed spring rate. This design allows vehicles to achieve more stable and linear dynamic responses, facilitating better vehicle control for the driver. They are mostly used in performance-oriented modified cars and racing vehicles. The downside is that comfort is affected. 6) Short springs are shorter and thicker than original factory springs. Installing short springs can effectively lower the vehicle's center of gravity, reduce body roll during cornering, make cornering more stable and smooth, and improve cornering handling. However, original factory shock absorbers are damped for comfort, so the combination of short springs and original shock absorbers is not very stable. They cannot effectively suppress the rebound and compression of short springs. When driving on bumpy roads, there will be an uncomfortable bouncing sensation. Over time, the service life of the shock absorbers will be greatly reduced, and oil leakage may occur. Of course, these conditions are relative; daily driving will not cause such severe damage. Try to avoid aggressive driving, as original factory shock absorbers cannot withstand high-load pressures.

huefra spring applications

To a large extent, disc springs are replacing cylindrical helical springs. They are commonly used in heavy machinery (such as presses) and weapons like artillery and aircraft as powerful buffering and vibration-damping springs. They are used as clamping springs for automobile and tractor clutches and safety valves, and as energy storage elements in mobile mechanisms. Disadvantage: Load deviation is difficult to guarantee. Disc springs can be divided into three categories based on cross-sectional shape: standard disc springs (rectangular cross-section), disc springs with radial slots, and trapezoidal cross-section disc springs. Standard disc springs are divided into two types: with support surface and without support surface. Disc springs with radial slots are based on standard disc springs, with several uniformly distributed slots cut radially. Slots can be cut from the inner hole towards the outer circle, or from the outer circle towards the inner hole. Trapezoidal cross-section disc springs can be divided into two types: those with inner edge thickness greater than outer edge thickness, and those with inner edge thickness less than outer edge thickness. Since the deformation and load values of a single disc spring often do not meet usage requirements, they can be used in groups to form disc spring assemblies (columns). Typical combination methods include: stacked disc spring assemblies, composite disc spring assemblies, and other disc spring assemblies. Compared with cylindrical helical springs, disc springs have the following characteristics: 1) The load-deformation characteristic curve is non-linear. 2) Disc springs are thin and easy to form assemblies, allowing modular assembly and replacement, which facilitates maintenance. 3) Disc springs with radial slots have zero-stiffness characteristics. This characteristic can be applied in situations where the spring force is required to remain basically stable within a certain deformation range. 4) The vibration absorption performance of disc springs is no less than that of cylindrical helical springs. When using stacked combinations, the friction between disc spring plates provides greater damping, dissipating impact energy.
