schlicker carstyling springs are typically 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, usually with gradually decreasing leaf lengths. Leaf springs can provide positioning, a degree of damping, and spring functionality. 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 tightness introduces 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.

schlicker carstyling spring principles

When leaf springs are installed in an automotive suspension and subjected to 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-around eye. A larger gap is left between the main leaf eye and the second leaf's wrap-around eye to allow for relative sliding during elastic deformation. In some suspensions, the ends of the leaf springs are not formed into eyes but use other support connection methods, such as rubber support pads. Flat rectangular steel plates are curved, and chassis springs made of several stacked leaves are installed with one end pinned to a hanger and the other end connected to the main beam using a shackle, allowing the spring to expand and contract. This design is suitable for medium and large trucks. Automotive leaf springs are extremely important. As is well known, leaf springs are composed of many steel leaves that are elastic, have uniform width and thickness, but vary in length. Their function is to connect the frame and axle in a suspended manner, exposed between the frame and axle, bearing the load impact from the wheels on the frame, reducing severe body vibration, and maintaining vehicle stability and adaptability to different road conditions. When leaf springs bear load impacts, they undergo extension movements, causing intense friction between the steel leaves, i.e., compression and tension phenomena. The two friction surfaces generate motion friction forces in different directions, causing the temperature of the leaf spring to rise, resulting in surface scoring and fine cracks. As the frequency of load impacts increases, the frictional force generated by the extension movement also increases. When the stress concentration point reaches the fatigue limit, it causes single-leaf or entire stack fracture. Kinetic principle tests have proven that for a steel component undergoing compression-extension motion, as the motion frequency increases, the component's temperature rises and strength decreases. Cracks appear at stress concentration points, gradually expanding and deepening, leading to damage upon reaching the fatigue limit. The same applies to leaf springs, although they have higher elasticity and are more durable than general steel components. Apart from other causes, the primary 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 and distribute stress, preventing surface scoring of the steel leaves; to reduce the intrusion of dust, dirt, and water, preventing corrosion; and to dissipate heat, preventing a decline in elastic strength. The general lubrication method is: perform lubrication after the new vehicle break-in period ends, and during use in summer and winter. For lubrication, first remove the leaf spring, open the central 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 (comparing the time required for one set of leaf spring lubrication to replacing a single broken leaf).

schlicker carstyling spring advantages and classification

The advantages of leaf springs are simple structure, reliable operation, low cost, and easy maintenance. It serves as both the elastic element of the suspension and the guiding device of the suspension. One end is hinged to the frame, allowing it to transmit various forces and torques and determine the runout trajectory of the wheel. At the same time, it also provides a certain degree of friction damping. Achieving three benefits at once, it is widely used in non-independent suspensions. Leaf springs are classified by shape: 1) elliptical leaf spring; 2) semi-elliptical leaf spring; 3) quarter-elliptical leaf spring; 4) single-leaf spring. Elliptical, semi-elliptical, and quarter-elliptical leaf springs are all composite-type leaf springs, relying on the friction between leaves to provide high cushioning and damping performance, widely used in the suspension systems of automobiles, tractors, and railway vehicles; Single-leaf springs consist of a single piece of spring steel, commonly used in mechanical equipment and instruments to clamp working components.

schlicker carstyling spring precautions

Due to product structure limitations, multi-strand springs generally feature high strength and good performance. The material must guarantee final performance in terms of spring strength and toughness. During the processing of multi-strand springs, note the following: 1 Support coils can be cold-wound or hot-wound according to product requirements. When using hot winding, the spring must not be heated to the point of sparking or whitening; the temperature for silicon-manganese steel must not exceed 850℃. The support coils and active coils must have effective contact, and the gap must not exceed 10% of the nominal inter-coil gap. 2 The characteristics of multi-strand springs can be determined by adjusting the lead; the pitch can be adjusted as necessary during winding. The pitch can be 3~14 times the wire diameter, but 8~13 times is generally preferred. The spring force is also closely related to free height, closed ends, outer diameter, and wire properties, and can be changed by adjusting one or more of these parameters. 3 Springs without support coils and springs with excessively thin wire diameters should not have welded ends, but the cable ends should not be obviously loose and must be deburred. For multi-strand springs requiring welded heads, the welding length should be less than 3 times the cable diameter (maximum no more than 10 mm). The heating length should be less than one coil, and the weld should be ground smooth after welding. During gas welding, the welded area should undergo local low-temperature annealing. 4 Spring surface treatment generally involves phosphating, but other treatments are also possible. If zinc or cadmium plating is required, hydrogen embrittlement relief must be performed after electroplating. After hydrogen relief, conduct a standing test on 3% (no fewer than 3 pieces); no fractures are allowed during the retest. Springs must be cleaned of surface dirt, salt marks, and oxide scale, using methods such as sandblasting or gasoline cleaning, but acid pickling is prohibited. 5 Important springs should be compressed for 24 hours, ordinary springs for 6 hours or compressed continuously 3~5 times, holding each time for 3~5 seconds. During compression, the gap between the spring and the mandrel should be 10% of the mandrel diameter; too small a gap makes operation difficult, while too large a gap easily causes bending deformation of the spring. If one spring breaks during compression, the rest must be reprocessed.
