Vehicle comfort has always been an important indicator for consumers to buy new cars. In the view of ordinary consumers, most of the factors affecting vehicle comfort are vehicle interior space, seat flexibility, etc. In fact, in addition to the above two points, the trailer suspension system is the main factor affecting the comfort. Different factors of suspension structure bring different driving experiences.
According to different structures, the trailer suspension system can be divided into two categories: independent suspension and dependent suspension.
As the name implies, independent suspension means that each wheel is separately hung under the body or frame through elastic components, rather than the wheels on both sides of the independent suspension are connected by an integral bridge.
McPherson independent suspension is one of the popular independent suspensions, which is generally used for the front wheels of trailers. The design is simple in structure, light in weight, small in space, more convenient in space layout of the engine, and relatively strong in shock absorption performance. The biggest advantage of McPherson independent suspension is that it takes up less space, because the upper cross arm design is cancelled, making more space available for the engine compartment. On the other hand, McPherson independent suspension has good responsiveness and handling, which is very suitable for sports vehicles equipped with large engines.
Although the McPherson independent suspension has many advantages, its disadvantages are also obvious. Because the McPherson independent suspension shock absorber and coil spring can only cushion the up and down swing of the vehicle, the lateral support is insufficient, and the roll is more serious when turning.
Multi link suspension uses various connecting rod devices to connect the wheels with the body. At present, it is more common to connect 4 to 5 connecting rods. Its advantages are simple structure and light weight. Reducing the space occupied by the suspension system can achieve the best position of the main sales caster angle, greatly reduce the front and rear road forces, improve the stability and comfort of accelerated braking, and ensure the stability of straight driving. Because the lateral deviation of the wheels caused by the extension or compression of the spiral spring is very small, it is not easy to cause non straight driving. When the vehicle is cornering or braking, the multi link rear suspension structure can make the rear wheels form toe in, improve the vehicle control performance and reduce understeer. At the same time, the compact structure increases the space of the rear seat and the trunk. For this reason, suspension has obvious advantages and is easy to adjust, so it is widely welcomed.
