What are the components of the automobile suspension system?

Depending on the type of suspension, the components used will be different, but the most basic springs and shock absorbers are the most basic.

The connecting rod structure will be available.

1. Springs There are leaf springs, coil springs, and torsion bar springs.

1. Leaf spring: This is the standard configuration of hard-core off-road vehicles, large trucks and cattle trucks. It is characterized by high strength and high reliability, which can be called a mechanical aesthetics, and there is absolutely no one or two.

True to its name, an elastic beam composed of many alloy springs (equal width and length, thickness can be equal or different), and the reason for the high strength is the story of a chopstick and a pair of chopsticks. It not only acts as a resilient person, but also as a guide. It is connected to the frame at one end, withstands all kinds of gravity, transmits all kinds of moments, and to a large extent, the undulating trajectory of the wheel on the road surface depends on it.

<> advantages: simple structure, high reliability, low cost, convenient maintenance. It not only plays a role in elasticity, but also plays a guiding role. And there is friction between the plates, and these frictions can help in shock absorption.

Disadvantages: It can only be used for non-independent suspension, its own weight, stiffness, discomfort, and relatively long, which also leads to the long distance between the front and rear overhangs of the car, and the wear of the joints and spring pins.

Because of these advantages and disadvantages, it is generally mounted on large hardcore off-road vehicles, such as the big G

2. a coil spring.

Nowadays, there are many parts used in cars with monolithic hard bridges. The feature is that the thickness and density of the spring can be changed, and the elastic value can be changed. It can both filter out vibrations and prevent the bottom of the frame.

<> advantages: simple structure, space-saving, large stroke, light weight, customizable, absorbing more energy, and saving lubrication.

Disadvantages: small load-bearing, high cost, must have a guide mechanism and shock absorber.

3. Torsion bar spring.

Torsion Bar translates to torsion bar spring. It is connected to the frame at one end, and the swingarm is connected to the wheel, which looks so complicated. The movement of the wheels is transmitted to the torsion bar (torsion bar spring) via the swing arm.

For example, when twisting a towel, the torsion bar is compared to a towel, after turning at a certain angle, the torsion bar also rotates and deforms (elastic deformation, recoverable), and the deformation at this time is that the torsion bar gains kinetic energy, and releases it after the wheel is out of obstacle, so that the wheel returns to its position.

Advantages: extremely high energy absorption, small footprint, high load-bearing.

Disadvantages: high cost, extremely high. Used on tanks.

Second, the function of the shock absorber is to suppress the impact of the road surface. When passing through a complex road, the spring will reciprocate, and if there is no shock absorber, the car will still rise and fall when returning to the flat road, so the shock absorber will suppress this up and down.

From the perspective of materials, it is classified into hydraulic type and inflatable type (also called nitrogen reduction). In terms of structure, it is divided into single cylinder and double cylinder, which are single cylinder air pressure, double cylinder oil pressure, and double cylinder oil and gas.

3. Connecting rods. <>

An automotive suspension system refers to a system of connecting structures between the body, frame, and wheels. It includes shock absorbers, suspension springs, anti-roll bars, suspension sub-beams, lower control arms, longitudinal rods, knuckle arms, rubber bushings and connecting rods. When the car is driven on the road surface due to the change of the ground vibration and impact, part of the force of these impacts will be absorbed by the tires, but most of them rely on the suspension device between the tires and the body to absorb.

The function of the automobile suspension system is to transmit the force and torque acting between the wheels and the frame, and to cushion the impact force transmitted from the uneven road surface to the frame or body, and attenuate the vibration caused by it, so as to ensure that the car can run smoothly. Automobile suspension can be divided into non-independent suspension and independent suspension. The structural feature of a non-independent suspension is that the two wheels are connected by a monolithic axle, and the wheels, together with the axle, are connected to the frame (or body) by an elastic suspension.

When one side of the wheel jumps due to the unevenness of the road, it will inevitably cause the other side of the wheel to swing in the transverse plane of the car, so it is called non-independent suspension. The structural characteristics of the independent suspension are that the axle is disconnected, and the wheels on each side can be connected with the frame (or body) through the elastic suspension alone, and the wheels on both sides can jump separately without affecting each other, so it is called independent suspension.

Suspension is an important assembly in the car, which connects the frame and the wheels elastically, which is related to the various performance of the car. From the outside, the sedan suspension is a car assembly that is more difficult to meet the perfect requirements, because the suspension must meet the comfort requirements of the car, but also meet the requirements of its handling stability, and the suspension is only composed of some rods, barrels and springs, but do not think that it is simple, the opposite aspect is opposed to each other.

To put it simply, the suspension system refers to the entire support system composed of the springs between the body and the tires, the shock absorbers and the connection parts of the frame. The function of the suspension system should be to support the body and improve the feeling of driving and riding, because different suspension systems are used, the suspension belongs to the chassis system, which is one of the four major systems of the car, connecting the wheels and the frame, and is mainly composed of three basic parts: elastic elements (springs, bushings), guides (swing arms) and shock absorbers. In addition, a number of special features are included, <>

The types of vehicle suspension system are: non-independent suspension: the structural characteristics of the non-independent suspension system are that the two wheels are connected by an integral frame, and the wheels together with the axle are suspended under the frame or body through the elastic suspension system, and the suspension system refers to the entire support system composed of springs and shock absorbers between the body and the tires.

The function of the suspension system should be to support the body and improve the ride feeling, and different suspension settings will make the driver have a different driving experience.

Suspension plays a decisive role in the handling performance of the car, so in order to cater to the needs of young people for cars, almost all car brands are vigorously promoting the handling performance of their products, and even adding more and more sports elements. These suspensions will be better for the support of the vehicle when braking sharply in some corners, but its weakness is that the cost is relatively high. A while ago, a certain model of Volkswagen was to reduce the cost of the original multi-link suspension.

The origin of the name "suspension" of the car is translated from the English "suspension", which originally means the state of hanging, hanging, hanging; But what is car suspension? It refers to the whole support system composed of springs and shock absorbers between the body and tires, which mainly plays the role of shock absorption. First of all, we need to understand what exactly is the role of suspension?

When our car is driving on the road, it will produce large and small bumps and vibrations due to different road conditions.

The suspension system is mainly composed of components such as elastic elements, guidance mechanisms and shock absorbers. The role of the elastic element is to absorb and transmit vertical loads, mitigating the impact caused by the car when driving on uneven roads. The function of the guide device is to transmit the longitudinal moment, the lateral force and the resulting moment, and ensure that the wheel has a certain motion law relative to the frame or the car body.

The action of the shock absorber inhibits the ** after the spring is absorbed.

It is composed of wheels, frames, elastic elements, guides, shock absorbers, these parts, each part contains some special functions, wheels, frames play a decisive role, is to control the overall structure of the car, other elements play a certain combination in the system, shock absorbers are mainly used to reduce vibration.

The suspension of an automobile consists of elastic elements, a guiding mechanism, and a shock absorber. The suspension is used to connect the body and the wheels. Without suspension, the car cannot run properly. There are many suspension structures, and there are two kinds of suspension in cars, one is independent suspension and the other is non-independent suspension.

Common independent suspensions in the world include MacPherson suspension, multi-link suspension, double wishbone suspension, double wishbone suspension, and double ball joint suspension.

Common non-independent suspensions in the world include integral axle suspension and torsion beam suspension.

There is no connection between the two coaxial wheels of the independent suspension, so there is no movement interference between the wheels of the independent suspension.

There is a connection between the coaxial wheels of a non-independent suspension, so there is a phenomenon of motion interference between the coaxial wheels of a car using a non-independent suspension.

This is also the reason why non-independent suspension is not as comfortable and handling as independent suspension.

Most cars have MacPherson suspension for the front, which is a relatively simple independent suspension. This suspension consists of an L-shaped control arm.

The MacPherson suspension is simple in structure, small in size and light in weight. This suspension also takes up very little space, and the cost of MacPherson suspension is low.

The MacPherson front suspension will be used in most cars with a front transverse engine.
