Take you to understand the leaf spring

The general concept of a leaf spring distinguishes between the special definition of a leaf spring, which may be called a feather spring, and is one of the most flexible elements used in a vehicle wheel; a suspension structure is a large-scale structure usually consisting of elastic elements (various springs) and steering institutions (arms and elements), and shock-reducing devices (various-speed reducer); and elastic components can be divided into steel plates, pneumatic springs, helical springs, torsion springs, which are more found in steel plates.

The general concept of a leaf spring and its function can be distinguished from the definition of a leaf spring itself. The leaf spring can also be referred to as a leaf spring and is one of the most commonly used elastic elements in automotive suspension. The suspension structure is an extensive system structure. In general, the suspension consists of elastic elements (various springs), guiding mechanisms (various arms and various beams), shock absorbing devices (various shock absorbers), and the elastic elements can be divided into leaf springs, tubes, coil springs. and torsion bar springs, with leaf springs being the most common.

In general, the shape of the leaf springs commonly used in trucks adopts a symmetrical cross-sectional structure, usually composed of multiple leaf springs of different lengths, different radii of curvature, and the same or different thicknesses to form a similar elastic resistance. Beam; The leaf spring suspension structure mainly consists of leaf springs, center bolts, spring clips, spiral ears and sleeves.

Currently, many dump trucks on the market use a non-independent leaf spring suspension, which is firmly connected to the axle with the upper and lower cover plates and the lower bearing plates via the center U-bolts and the front roller. The ears are connected with pins and clips. The rear end link is pinned to the pivot link on the frame to provide a moving pivot point for the hinge. Because the mass of the dump truck suspension varies widely, the auxiliary leaf spring assembly is typically located above the main leaf spring assembly. so that depending on the different load plays a corresponding role.

In commercial vehicles, leaf springs are generally used as the main elastic components. The main reason is that leaf springs can connect the axle to the body very well. The impact force is transmitted to the frame to play the role of buffer force transmission and shock absorption. The main task of the leaf spring is to transmit all the forces and moments acting between the wheels and the body, and to relieve the shocks of the bumpy road surface transmitted to the body. The load and the resulting vibration of the bearing system can ensure the normal driving operation of the vehicle. In addition to the damping effect, the leaf spring also functions as a guide mechanism and damping mechanism during the running operation of the vehicle body, and controls the prescribed trajectory of the vehicle body wheels to ensure good operability and stability.
