leaf spring

The main function of leaf springs is to provide comfort to the passengers by minimizing the vertical vibration caused by the nonuniformity of road geometry.

This paper deals with the behaviour of the so-called cross-spring pivot, a flexible element connecting two members of a construction and consisting of two flat springs that cross each other at an angle of, for instance, 90 degrees.

Cross-spring pivots have been widely employed over the last decades in a broad variety of precision engineering applications due to the high motion repeatability achieved thanks to the absence of stick slip and clearance. In this paper, the non-linear effect of the anticlastic curvature of the leaf-springs is considered for the accurate analytical modeling of the elasto-kinematic behavior of cross-spring pivots

Solve the problem of soft spring of shock absorber and restore the performance of shock absorber. Using the buffering principle, the spring hanger bushings is significantly improved, and the comfort of Mercedes-Benz is enjoyed. Protect the shock absorber and suspension system from oil seals of the universal leaf spring bushings. It can reduce spring elasticity, increase ground clearance, increase chassis rigidity and anti-roll force. It is good for the shackle rubbers, the removing leaf spring bushings is smaller, and the natural service life will be extended.

The role of the leaf spring is to connect the frame and the axle in the form of suspension, exposed between the frame and the axle, withstand the load impact of the wheel on the frame, reduce the violent vibration of the body, and maintain the smoothness of the vehicle and the adaptability to different road conditions. 1, multiple leaf springs: By a number of pieces of length, the same width of the steel sheet stacked together. The steel plates of multiple leaf springs are stacked into an inverted triangle shape, the longest steel plate at the top and the shortest steel plate at the bottom, the number of steel plates is related to the weight of the supporting bus, the thicker and shorter the steel plate, the greater the rigidity of the spring. However, when the leaf spring is used for a long time, the pieces will slide and friction each other to produce noise. The relative friction between the steel plates will also cause the spring deformation, resulting in uneven driving. ​2, less leaf spring: by the two ends of the thin middle thick, equal width and length of the steel sheet superimposed. The steel plate section of the small leaf spring changes greatly, from the same stiffness (that is, the same carrying capacity), the small leaf spring is about 50% lighter than the multi-leaf spring, reducing fuel consumption and increasing ride comfort. Moreover, there is a point contact between the spring pieces, which reduces the relative friction and vibration, and increases the ride comfort.

Steel plate bushing is a kind of accessories used outside mechanical parts to achieve sealing, wear protection and other functions, which refers to the ring sleeve that plays the role of liner. It can be used in many different cars, including those with factory suspension systems. The role of the bushing is to absorb the impact of the collision and protect the brake disc from dust and debris. In addition, the steel plate bushing can also be adjusted to work properly, but it is highly recommended that you let a professional perform this task to ensure safety. Now, you can find many different designs of bushings that you can purchase and install into your car. However, there are also some manufactured to improve the performance of the brake. This means that it will be harder for you to put pressure on the brakes while driving, but easier to maintain brake performance.

A McPherson front suspension rigid-elastic coupling model was established by ADAMS/CAR, and the sensitivity of the suspension rubber bushing stiffness was analyzed by ADAMS/insight. The bushing stiffness, which has great influence on wheel positioning parameters, was selected as the design variable, and the minimum variation of wheel camber Angle, front beam Angle, kingpin internal Angle and kingpin rear Angle was taken as the objective function. The wheel positioning parameters were improved by experimental design and multi-objective optimization method. The results show that the kinematic characteristics of suspension can be effectively improved by changing the axial stiffness, torsional stiffness, radial stiffness, axial stiffness and torsional stiffness of front bushing on the lower control arm shaft. After optimized design, the suspension performance is obviously improved compared with the original scheme.

Leaf springs: It is composed of multiple steel plates with unequal lengths and unequal curvatures. After installation, the two ends naturally bend upwards. When the impact force from the road to the wheels comes, the composite leaf spring will deform, which will play the role of cushioning and vibration reduction, and also play the role of guiding and transmitting force when arranged longitudinally. Most of the non-independent suspensions use parabolic springs as elastic elements, which can save guide devices and shock absorbers, and have a simple structure. Leaf springs are the most widely used elastic element in automobile suspension. It is composed of several alloy spring pieces of equal width but unequal length (the thickness can be equal or not). An approximately equal strength elastic beam.

Leaf Spring (Leaf Spring) is the most widely used elastic element in automobile suspension, it is composed of a number of pieces of equal width but not equal length (thickness can be equal, also can not be equal) of alloy spring pieces combined into an approximate equal strength of the elastic beam.
