German daiker springs daiker models daiker prices

daiker springs are commonly used in wheeled vehicle suspensions. Initially known as laminated or bracket springs, and sometimes as semi-elliptical or cart springs, they are one of the oldest spring forms, dating back to the Middle Ages. Leaf springs consist of long, arc-shaped spring steel with a rectangular cross-section. In the most common configuration, the center of the arc provides the axle location, while loops formed at either end attach to the vehicle chassis. For very heavy vehicles, leaf springs can be made from multiple leaves stacked together, typically with progressively shorter leaves. Leaf springs can be used for positioning and a degree of damping as well as spring function. Although interleaf friction provides damping, it is poorly controlled and results in static friction during suspension movement. For this reason, some manufacturers have begun using single-leaf springs. Leaf springs can be connected directly to the frame at both ends, or directly at one end, usually the front, with the other end connected via a shackle or short swing arm. The tension creates a tendency for the leaves to elongate under compression, thereby making the elasticity softer. Some springs terminate in a recessed end, called a spoon end (rarely used), for supporting rotating components.

daiker spring installation and removal

Hydraulic lift hand trucks are widely used in production. During maintenance of their pressure oil pumps, we found that the pressure spring responsible for returning the pump's piston rod and the truck's pressure arm has a wire diameter of n and stores an elastic force of up to 1000N, making its installation and removal very difficult. This often delays troubleshooting and directly impacts production progress. Previous measures taken were ineffective. Therefore, I designed a pressure spring installer/remover as shown in Figure 1. The tool consists of a lower pressure lever 1, pressure blocks 10, connecting pins 14, nuts 1, spherical washers 12, upper pressure lever 13, locating sleeve 16, and levers. During operation, rotate the nut 11 to the appropriate position so that the cylindrical head claw of the lower pressure lever 1 contacts the vehicle body 2. Two pressure blocks 10 press symmetrically on the washer 6. Tighten the nut n to pull the tie rod 15, causing the upper pressure lever 13 and lower pressure lever 1 to move relative to each other, forcing the pressure spring to compress. When the washer 6 clears the cylindrical pin 7, the pressure wheel axle 9, pressure wheel 8, and cylindrical pin 7 can be removed. Then, loosen the nut 11, remove the installer/remover, and take out the pressure spring to disassemble, inspect, and repair the pressure oil pump. The locating sleeve 16 on the installer/remover is a key component. During manufacturing, one end features an internal spherical surface with a slot hole in the middle, and the other end is an inclined flat surface, forming an interference fit with the pressure lever. It must make good contact with the spherical washer 12 and the ball head of the lever 15. The pressure block 10 and connecting pin 14 have a clearance fit to ensure flexible rotation. The connecting pin 14 and upper pressure lever 13 have an interference fit. The connecting shaft 18 and pressure lever have a clearance fit.

daiker spring classification

1) Torsion springs are springs that withstand torsional deformation; their working part is also closely wound into a helical shape. The end structure of a torsion spring is processed into various shapes of torque arms rather than hook loops. Torsion springs utilize the lever principle, twisting or rotating elastic materials with softness and high toughness to store significant mechanical energy. 2) Extension springs are helical springs that withstand axial tensile forces. When not under load, the coils of an extension spring are generally tightly closed with no gap. 3) Compression springs are helical springs that withstand axial compressive forces. The material cross-section is mostly circular, though 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 forms. There is a certain gap between the coils of a compression spring. When subjected to external loads, the spring contracts and deforms, storing deformation energy. 4) Progressive springs adopt a design with inconsistent thickness and spacing. The advantage is that under low pressure, the section 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, benefiting driver control. They are mostly used in performance-oriented modified cars and competitive vehicles, though comfort is compromised. 6) Short springs are shorter and thicker than original factory springs. Installing short springs effectively lowers the vehicle's center of gravity, reduces body roll during cornering, makes cornering more stable and smooth, and improves cornering handling. However, original 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, causing an uncomfortable bouncing sensation on bumpy roads. Over time, this significantly shortens the life of the shock absorbers and may cause oil leaks. Of course, these conditions are relative; daily driving will not cause such severe damage. Avoid aggressive driving, as original shock absorbers cannot withstand high-load pressures.

daiker spring functions and applications

1) Reset function: Springs deform under external force and return to their original state when the force is removed. Many tools and devices utilize this property for resetting. For example, reset springs are installed on the hinges of many building doors, allowing them to automatically reset after people pass through. This function is also used in automatic umbrellas, mechanical pencils, and other convenient items. Additionally, various buttons and keys require reset springs. 2) Drive function: Mechanical clocks and wind-up toys are driven by tightening mainsprings. When tightened, the mainspring bends and deforms, storing elastic potential energy. Upon release, this energy converts to kinetic energy, driving rotation through a transmission mechanism. Toy guns, starting pistols, and military firearms also operate using this spring property. 3) Buffering function: Springs are installed between the frame and wheels of locomotives and automobiles to use elasticity to reduce vehicle bumps. 4) Vibration and 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.
