German technika springs technika models technika prices

technika springs are mechanical energy storage structures, primarily used in ancient ballistae and other crossbow-type weapons. Torsion springs store energy by twisting or rotating elastic materials that are soft and highly tough, thereby imparting a certain amount of mechanical energy to the projectile. Modern torsion spring torsion bars are mostly made of steel with good elasticity, and their forms have varied greatly. Examples include the hairsprings in mechanical watches, power springs in toy gyro guns, and torsion bars in tanks and automobiles. Torsion bars have a small volume and high torque, making them excellent shock absorbers for transportation vehicles.

technika spring features

1) High stiffness, strong buffering and vibration absorption capability, capable of bearing heavy 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 properties. 3) Using the same disc springs in different combination methods can significantly vary the spring characteristics. 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 greater the number of springs, the higher the load. 5) Short stroke, heavy load, small space requirement, convenient for combined use, easy maintenance and replacement, economical, high safety, and long service life.

technika spring structure and principle

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 control arm, which is connected to the wheel. One end of the torsion bar spring is connected and fixed to the vehicle frame, while the other end is connected to the wheel via the control arm. When the wheel encounters an obstacle on the ground and jumps upward, the wheel drives the control arm to rotate around the axis of the torsion bar 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 quickly return to their original positions. During the manufacturing of torsion bar springs, the torsion bar is pre-twisted to create a permanent torsional deformation, giving it a certain level of prestress. The direction of the pre-applied twist is the same as the direction of twist during operation on the vehicle, aiming to reduce actual stress during use and extend service life. Note that left and right torsion bars are not interchangeable.

technika spring functions and applications

1) Reset function: A spring deforms under external force, and once the force is removed, the spring returns to its original state. Many tools and devices utilize this property of springs for resetting purposes. For example, many building doors have reset springs installed on their hinges; after people enter or exit, the door automatically resets. This feature has also been used to create convenient items like automatic umbrellas and mechanical pencils. Additionally, various buttons and keys rely on reset springs. 2) Driving function: Mechanical clocks and wind-up toys operate by tightening a mainspring. When the mainspring is tightened, it bends and stores a certain amount of elastic potential energy. Upon release, this elastic potential energy converts into kinetic energy, driving rotation through a transmission mechanism. Toy guns, starter pistols, and military firearms also utilize this property of springs. 3) Cushioning function: Springs are installed between the chassis and wheels of locomotives and automobiles, using the elasticity of the springs to reduce vehicle vibrations caused by bumps. 4) Vibration sound generation function: When air flows through the reed holes of harmonicas and accordions, it strikes the reeds, causing them to vibrate and produce sound.
