German erexim springs erexim models erexim prices

erexim 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 materials. 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.

erexim spring structure

The torsion bar spring itself is a torsion bar made of spring steel. The cross-section of the torsion bar is usually circular, with a few being tubular or rectangular. Its ends can be shaped as splines, square, hexagonal, or cylindrical with flat surfaces, so that one end is fixed to the vehicle frame and the other end is fixed to the suspension arm, which is connected to the wheel.

erexim 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 consists of twisted arms processed into various shapes, 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 tightly closed with no gaps. 3) Compression springs are helical springs that withstand axial compressive forces. The material cross-section used is mostly circular, but rectangular and multi-strand steel wires are also used. Springs generally have equal pitch. Shapes of compression springs include: cylindrical, conical, convex, concave, and a small number of non-circular shapes. There are certain gaps between the coils of compression springs. When subjected to external loads, the spring contracts and deforms, storing deformation energy. 4) Progressive springs adopt designs with inconsistent thickness and spacing. The advantage is that when pressure is low, the part with a lower spring rate absorbs road undulations, ensuring ride comfort. When pressure increases to a certain level, the thicker part of the spring supports the vehicle body. The disadvantage of this type of spring is indirect handling feel and poor precision. 5) Linear springs have consistent thickness and 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 drivers. They are mostly used in performance-oriented modified cars and racing vehicles. The downside is, of course, affected comfort. 6) Short springs are shorter than original factory springs and are sturdier. 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 vehicle cornering handling. However, original shock absorbers have damping settings biased towards 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 jumping sensation. Over time, the lifespan 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 shock absorbers cannot withstand high-load pressures.

erexim spring features and applications

Features: Compared to ordinary compression or extension springs, their spring force is very constant, outputting a nearly linear spring force. This ensures that products do not change due to variations in spring force during use. In narrow and long spaces, space can be minimized 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 pressing devices, cables, stapler springs, power tools, car ashtrays, locomotive carbon brush accessories, medical devices, mobile phone holders, etc.
