German brand kg spring brand kg model brand kg price

brand kg springs consist of tension springs and connecting springs. The pitch and helix direction of the tension and connecting springs are identical. A dedicated fixture is used to clamp one end of the tension spring and screw it into the connecting spring. The other end of the tension spring is then rotated and fitted onto the other end of the connecting spring. Rotational force is used to screw the connecting spring into the interior of the tension spring, forming a ring spring. This utility-model ring spring does not affect the shape and elasticity of the connection area and provides a secure connection for various applications requiring ring springs. The ring spring is composed of alternating stacked washer-like spring steel discs with inner conical and outer cylindrical surfaces, and washer-like spring steel discs with inner cylindrical and outer conical surfaces. The number of inner and outer ring pairs in the ring spring is determined based on the magnitude of the load it bears and the required deformation. Ring springs are used in applications with limited space that require strong buffering.

brand kg spring principle

When leaf springs are installed in an automobile suspension and bear positive vertical loads, each spring leaf deforms under stress, tending to arch upward. At this time, the axle and frame move closer together. When the axle and frame move apart, the positive vertical load and deformation on the leaf spring gradually decrease, sometimes even reversing. The eye of the main leaf is heavily stressed and is a weak point. To improve the stress condition of the main leaf eye, the end of the second leaf is often bent into an eye that wraps around the outside of the main leaf eye, known as a wrap eye. A large gap is left between the main leaf eye and the second leaf wrap eye to allow relative sliding between the leaves during elastic deformation. In some suspensions, the ends of the leaf springs are not formed into eyes but use other support and connection methods, such as rubber support pads. Flat rectangular steel plates are curved and stacked to form chassis springs. One end is mounted on a hanger with a pin, and the other end is connected to the main beam using a shackle, allowing the spring to expand and contract. This design is suitable for medium and large trucks. Automobile leaf springs are very important. As is well known, leaf springs are composed of many steel leaves that are elastic, have consistent width and thickness, but vary in length. Their function is to connect the frame and axle via suspension, exposed between the frame and axle, bearing the load impact from the wheels on the frame, reducing severe vehicle vibration, and maintaining driving stability and adaptability to different road conditions. When bearing load impacts, leaf springs undergo extension motion, causing intense friction between the steel leaves, resulting in compression and tension phenomena. The two friction surfaces generate motion friction forces in different directions, causing the temperature of the leaf spring to rise, leading to surface scoring and fine cracks. As the frequency of load impact increases, the frictional force generated by the extension motion also increases. When the stress concentration point reaches the fatigue limit, it causes single-leaf or entire-stack fracture. Kinetic principles and tests prove that a steel component undergoing compression-extension motion experiences a temperature rise and strength decrease as motion frequency increases. Cracks appear at stress concentration points, gradually expanding and deepening until failure occurs at the fatigue limit. Leaf springs behave similarly, though they have higher elasticity and are more durable than general steel components. Apart from other causes, the main reason for leaf spring fracture is poor lubrication, which should be taken seriously by drivers and technical management personnel. Timely lubrication of leaf springs is essential to reduce friction, distribute stress, prevent surface scoring of steel leaves; reduce intrusion of dust, dirt, and water to prevent corrosion; and dissipate heat to prevent a decrease in elastic strength. General lubrication procedures should be performed after the new vehicle break-in period, and during summer and winter operation. For lubrication, first remove the leaf spring, open the center bolt to separate the steel leaves, then evenly apply lithium-based or graphite grease to both sides of the leaves. After reassembly, an oil film forms between the two friction surfaces (completing the lubrication of one set of leaf springs takes only as long as replacing one broken leaf).

brand kg 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. The ends can be shaped as splines, squares, hexagons, or cylindrical with flats, allowing one end to be fixed to the 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 frame, and the other end is connected to the wheel via the suspension arm. When the wheel encounters a ground obstacle and jumps upward, the wheel drives the suspension arm to rotate around the torsion bar axis by a certain angle, causing torsional deformation (elastic deformation) of the torsion bar. Meanwhile, the elastic energy stored in the torsional deformation of the torsion bar is released when the wheel leaves the obstacle, allowing the force transmission mechanism and wheel to quickly return to position. During manufacturing, the torsion bar is pre-twisted to create a permanent torsional deformation, providing a certain preload. The direction of the applied pre-torsion is the same as the torsion direction during vehicle operation, aiming to reduce actual stress during operation and extend service life. Note that left and right torsion bars are not interchangeable.

brand kg spring classification

1) ISO International Standard Type: ISO gas springs are the most common typical type of gas spring. All technical parameters comply with the ISO11901 international standard for gas springs and Chinese national standards; B type gas springs also comply with the gas spring standards of companies such as FORD-WDX3560 (Ford), GM-M-150 (General Motors), and Renault (Renault). 2) Compact Structure Type: The compact structure type is also called J type gas spring, a series product within the gas spring range, fully named J type compact structure gas spring. The J type compact structure gas spring is popular among mold designers. Compared to the B series gas springs, it has a shorter cylinder base length, resulting in a shorter overall length, which can reduce the design height of the mold, making it one of the preferred choices for mold-specific gas springs. 3) Ultra-Compact Type: This is the model with the shortest base length among gas springs worldwide. Simultaneously, its outer diameter is one size smaller than other types of gas springs (except for the T type extra-slim structure), but the piston rod diameter is the same, resulting in a small size with high force. The C type gas spring performs no worse than the ISO standard type gas spring in all aspects when the required working stroke is not too long. 4) Extra-Slim Structure Type: This is the most compact cylinder diameter type among gas springs, featuring a piston seal design, with an outer diameter even smaller than the ultra-compact type. The working stroke of the H type gas spring series generally does not exceed 50mm, and its performance in all aspects is no inferior to the C type gas spring.
