The type of automobile suspension-leaf spring non-independent suspension

Release time：2024-06-21

Today, with the rapid development of automobile technology, as an important part of the automobile chassis, the design and performance of the suspension system directly affect the handling, comfort and safety of the vehicle. Among the many suspension systems, the leaf spring non-independent suspension has been widely used in the automotive industry because of its simple structure, high reliability, and strong carrying capacity.

Leaf spring type non-independent suspension is a suspension system that uses leaf springs as elastic elements. In this kind of suspension system, the leaf spring not only plays the role of buffering and damping, but also serves as a guiding mechanism and a force transmission component. Due to its compact structure and low manufacturing cost, leaf spring non-independent suspension is widely used in trucks, passenger cars, and some off-road vehicles and pickup trucks.

Leaf spring type non-independent suspension is mainly composed of leaf springs, shock absorbers, guides and stabilizers. Among them, the leaf spring is the core component of the suspension system, which is usually formed by superimposing multiple spring sheets with unequal length and unequal curvature, and the elastic support is realized by connecting the two ends with the frame and the axle.

When the vehicle is running on an uneven road surface, the leaf spring is subjected to impact and vibration from the road surface. At this time, the leaf spring absorbs and buffers these shocks and vibrations through its own elastic deformation to ensure the smooth running of the vehicle. At the same time, the deformation of the leaf spring will also cause the axle to move up and down relative to the frame, thereby changing the contact state between the wheels and the ground, and improving the driving stability and comfort of the vehicle.

Characteristics of 3. leaf spring non-independent suspension

1. Simple structure and low manufacturing cost: The structure of the leaf spring type non-independent suspension is relatively simple, and complicated connectors and supporting structures are not required, so the manufacturing cost is low.

2. Strong load-bearing capacity: Due to the superimposed design of the leaf spring, it has a high load-bearing capacity and impact resistance, which is suitable for models with larger loads.

3. High reliability: The number of parts of the leaf spring non-independent suspension is small, and the connection between the parts is relatively simple, so it has high reliability.

4. Convenient maintenance: The maintenance and replacement of the leaf spring non-independent suspension is relatively simple, does not require complicated operations and equipment, and reduces maintenance costs.

Application scope of 4. leaf spring non-independent suspension Leaf spring non-independent suspension has been widely used in the field of commercial vehicles due to its strong load-bearing capacity and high reliability. For example, in trucks, passenger cars, and some off-road vehicles and pickup trucks, leaf spring non-independent suspensions are common choices. In addition, in some special purpose vehicles, such as military vehicles, engineering vehicles, etc., leaf spring non-independent suspension is also used because of its good carrying capacity and adaptability.
