The suspension is an important components connecting the chassis and the frame. The supporting force, braking force, driving force, etc. of the vehicle are transmitted through the suspension system, and it can also reduce the impact of harsh roads on the vehicle and ensure the stability of the vehicle , Its importance is self-evident. Suspension is generally divided into independent and non-independent truck suspension system components

The difference between non-independent truck suspension system components and independent truck suspension system components

The structure of the suspension, especially the structure of the guiding mechanism, varies with the different elastic elements used, and sometimes very different. When using spiral bombs and gas springs, a more complicated guiding mechanism is required. When the leaf spring is used, since the leaf spring itself can serve as a guiding mechanism and has a certain damping effect, the suspension structure is greatly simplified. Therefore, most of the non-independent truck suspension system components use leaf springs as elastic elements.

The characteristic of the independent truck suspension system assembly is that the wheels on both sides are independently connected to the frame or body elastically. When one wheel is impacted, the base movement will not directly affect the other wheel. The axles used in the independent truck suspension system components are short-opening, which can lower the installation position of the engine, which is conducive to lowering the center of gravity of the car and making the structure compact. The independent truck suspension system components allow a larger jump space for the front wheels, which facilitates the selection of softer elastic elements to improve smoothness. At the same time, the sprung mass of the independent truck suspension system components is small, which can improve the adhesion performance of the car wheels.

Non-independent truck suspension system components are widely used in the suspension of general trucks and passenger cars because of their simple structure and reliable operation, but they are often only used as rear suspensions on cars. The leaf spring is used as the elastic element of the non-independent truck suspension system components. Because it acts as a guide device and has a certain damping effect, the suspension system is greatly simplified.

The independent truck suspension system components use a disconnected axle, and the wheels on both sides are connected to the frame or the body through the independent truck suspension system components. Each wheel can move independently without interfering with each other. Independent truck suspension system components are widely used in the steering wheels of cars and trucks with a load of less than 1000kg, which can meet the requirements of ride comfort and handling stability. However, independent truck suspension system components have complex structures, high manufacturing costs, and inconvenient maintenance.

Coil springs and torsion bar springs are often used in the elastic components of independent truck suspension system components, and leaf springs and other forms of springs are rarely used. According to the different suspension guiding devices, independent truck suspension system components can be divided into double wishbone, single wishbone, trailing arm type, single inclined arm, multi-rod type and sliding column link (swing arm) type (MacPherson type) ) And many others. At present, the unequal-length double-arm type, the sliding column linkage type and the inclined single-arm type are more commonly used. For semi-trailers, due to the need for strong load-bearing capacity, all non-independent truck suspension system components are used, and there are four common types of suspensions for semi-trailers.

Rigid suspension

Rigid suspension is that the left and right wheels are connected by an axle, and the body chassis directly acts on the axle. The shock absorption effect of this kind of axle is very poor, and the longitudinal unevenness of the road surface is completely adapted by the swing of the balance beam, so as to maintain the relative balance of the front and rear axles. This kind of suspension is currently used relatively little, and is mainly used on low-speed axle low-plate semi-trailers that carry goods at low speeds. It is a kind of non-independent truck suspension system components.

Single point suspension

The single-point suspension is to reduce the common leaf spring front and rear brackets into a single bracket connected to the car body. Its stress points are shared on the front and rear axles. Compared with the ordinary leaf spring suspension, the single-point suspension has a higher bearing capacity. Big. This kind of suspension is rarely used on ordinary semi-trailers, and is mainly used on heavy vehicles. It is a kind of non-independent truck suspension system components.

Steel plate suspension

Steel plate suspension is our common leaf spring, its full name is series-connected leaf spring balance suspension. It is mainly composed of leaf springs, suspension bearings (commonly known as lifting lugs), connecting rods, U-shaped bolts and other parts. The longitudinal force of the car body falls directly on an axle. The biggest advantages of this kind of suspension are low price, good reliability, and easy maintenance. At present, more than 80% of ordinary semi-trailers in China use leaf spring balanced suspension, which is a components of non-independent truck suspension system components.

Air suspension

The most obvious feature of the air suspension is its airbag-type air spring. The air spring itself is relatively light, the friction of the air medium in the airbag is small, there is almost no noise during operation, and its life span is 2-3 times that of a leaf spring. However, when an air spring is used, a rod system that can transmit various forces and moments other than the vertical force must be provided, so the suspension structure is complicated; in addition, the air spring has strict requirements for sealing, and its cost is also high. At present, most domestic air suspension trailers are used in high-end fields such as precision instrument transportation, tobacco transportation, and hazardous chemical transportation. They are a kind of non-independent truck suspension system components.
