German mubea springs, mubea models, mubea prices

mubea spring is a special type of extension spring, suitable for applications with large elongation and constant load. Constant-force springs consist of spirally wound metal strips. The inner side of the strip is curved so that each turn wraps tightly around the preceding inner turn. When the metal strip is stretched (twisted), internal stress resists the load force, similar to ordinary extension springs, but the spring rate remains nearly constant (zero). See the load/torsion diagram. In use, an ID is typically used to wind this spring tightly onto a drum, with its free end connected to the load, acting like a counterweight. Alternatively, the free end can be fixed, allowing the spring itself to provide the working force, similar to carbon brushes in electrical devices.

mubea spring classification

1) Based on load characteristics during operation, helical springs are classified into compression, extension, and torsion types; 2) Based on structural features, they are divided into cylindrical helical springs and variable-diameter helical springs; variable-diameter helical springs mainly withstand compressive loads; 3) Based on shape characteristics, they are classified as conical, spiral volute, concave, and convex. 4) In production and application, helical springs are further divided into large and small helical springs based on forming method and wire diameter; the former are typically hot-formed, while the latter are cold-formed. 5) Other classifications: Helical springs have various types. By appearance: standard cylindrical helical springs; variable-diameter helical springs. By helix direction: left-hand springs; right-hand springs. Variable-diameter helical springs include: conical helical springs, spiral volute helical springs, and concave helical springs. Cylindrical helical springs feature simple structure, easy manufacturing, and wide application. Their characteristic curve is linear, allowing them to function as compression, extension, or torsion springs. When high loads are present with limited radial dimensions, two compression springs of different diameters can be nested to form a combination spring.

mubea spring structural classification

Based on loading nature, springs are classified into extension springs, compression springs, torsion springs, and bending springs. By shape, they include disc springs, ring springs, leaf springs, helical springs, truncated conical volute springs, and torsion bar springs. By manufacturing process, they are divided into cold-coiled and hot-coiled springs. Standard cylindrical springs are widely used due to their simple manufacturing, adaptable designs for various load conditions, and straightforward structure. Spring materials generally require high elastic limits, fatigue limits, impact toughness, and good heat treatment properties. Common materials include carbon spring steel, alloy spring steel, stainless spring steel, copper alloys, nickel alloys, and rubber. Manufacturing methods include cold coiling and hot coiling. Wire diameters less than 8 mm are generally cold-coiled, while those greater than 8 mm are hot-coiled. Some springs undergo presetting or shot peening after manufacturing to enhance load capacity.

mubea spring features

Suspensions using torsion bar springs are lighter in weight, simpler in structure, and require no lubrication. Vehicle height can be easily adjusted automatically by changing the installation angle of the torsion bar spring's fixed end. Torsion bar springs store more elastic energy per unit volume and have lower mass compared to helical springs, offering a compact structure that is easy to arrange. They are commonly used in off-road vehicles, light passenger cars, and trucks. Torsion bar springs are classified by cross-sectional shape into circular, tubular, and strip types. Solid circular torsion bars are the most common due to their simple structure. For assembly, both ends are machined with splines, hexagonal, or square shapes. Splined connections are preferred due to the smaller size of the spline ends. 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. Spline teeth should not be excessively long provided the crushing stress remains within permissible limits. Torsion bar springs typically use involute splines according to GB3478. The JSB2705 standard recommends a standard pressure angle of 45°, 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 into the spline teeth at both ends.
