Automobile suspension types can be divided into independent suspension and dependent suspension according to the main categories. McPherson suspension and multi-link suspension belong to the category of independent suspension. Dependent suspension is the so-called torsion beam suspension. The cross beam runs through the bottom of the car, and the independent suspension is classified into more categories, including multiple connecting rods.

Strictly speaking, an independent suspension with more than 2 links is considered as an independent suspension. After all, the suspension is only simple in structure. Double wishbone suspension; Mcpherson suspension.

Vertical reaction, longitudinal reaction, lateral reaction and torque generated by reaction on road wheels are transmitted to the frame (or frame) to ensure the normal running of the automobile, that is, to play the role of power transmission; Elastic elements and shock absorbers are used for buffering and damping. ?

Several suspension force transmission parts are used to make the wheels jump relative to the frame or car body according to a certain trajectory, that is, to play a guiding role, and additional elasticity is used in the suspension elements of the side stabilizer to avoid excessive lateral tilt of the car body under driving conditions such as steering.

Among these suspension structures, air suspension is relatively rare. It is a suspension system with air springs and corresponding air pumps, gas tanks and other devices. By adjusting the hardness and length of each air spring, air suspension can make multiple wheels of the same car show different suspension performance under driving conditions.

That is, to achieve the balance of comfort, sportiness, passability and stability, this suspension is mostly used in expensive models, such as Hyundai Janes, Toyota Crown, Audi A6L, Audi Q7, Volkswagen Phaeton, Volkswagen Touareg V6, BMW 7 Series, etc.

McPherson suspension can be said to be the most mature suspension system, which is also very common in China. It has the characteristics of simple structure, light weight, small occupied space, good damping effect, convenient installation of the engine, relatively weak anti-roll and braking ability and poor stability. ?

McPherson suspension is mostly used for the front suspension of family cars. Double wishbone suspension is actually similar to McPherson suspension, which can be said to be an upgraded version of McPherson suspension. Double wishbone suspension adds a wishbone in the middle of McPherson suspension, which has better shock absorption and stability than McPherson suspension, but it takes up a lot of space and costs a lot.

So it is generally used in the upper class. Multi-link free suspension is the most complicated suspension, which needs a large number of links, including three links, four links and five links. All the functions of double wishbone suspension can be provided, which can be divided into front suspension and rear suspension. If it is a front suspension, it can reduce the weakness of understeer and make the steering feel more accurate.

If it is a rear suspension, the rear wheel can change its angle when rolling, making driving feel more comfortable. The disadvantage is that it takes up a lot of space because it is too complicated, and even sacrifices some space in the trunk, which is also the most expensive in cost. Torsion beam suspension is widely used in automobile rear wheels.

Torsion beam bearing main vertical and lateral moments; Longitudinal swing arms welded on the left and right sides of the torsion beam; An elastic element arranged at the front end of the longitudinal swing arm and a connecting bracket connected with the vehicle body; The spring damping system consists of four parts. In practical application, the wheels of dependent suspension are installed at both ends of the integral axle. ?

When one wheel moves and jumps, the other wheel jumps accordingly, causing the whole body to vibrate or tilt. This suspension system has the advantages of simple structure, convenient maintenance, small floor space and large bearing capacity, and is mainly used for special vehicles such as trucks, ordinary buses and small cars.

However, poor comfort and poor handling are also inevitable defects. In fact, the suspension system has always been said to be "three-point structure and seven-point adjustment". Different suspension structures only determine the physical characteristics of the vehicle to a certain extent, but the later adjustment is more important.

For example, the rear suspension of the old Honda Civic TypeR is not independent, but it can also be one of the fastest front-wheel drive vehicles on the North Ring Road of New Boglin.
