Today’s consumers are not just looking at the outside when buying a car, more consumers are beginning to pay attention to the inner performance. In the inner performance, the performance of the chassis suspension is the most easily overlooked by consumers. The quality of the chassis suspension is related to the quality of the driving of a car, and the driving quality will directly affect our driving experience.
Suspension as a part of the chassis, the impact of the suspension on the entire chassis is very large, a good suspension can make the performance of the chassis even more powerful. In general, the suspension on modern cars can be roughly divided into two types: independent suspension and non-independent suspension.
AA-TOP is a group company specialized in auto spare parts with several high-tech production bases in China which including development,production and sales.
The company now had various kinds of international advanced production lines and high-quality professionals, committed to new product development and brand operations with strict scientific management which leads to remarkable results.
AA-TOP enterprise is specialized in producing Engine Mount, Strut Mount, Control Arm, Tie Rod, Bushing, Timing Belt, V-Ribbed Belt and Cogged V-Belt. Products had passed ISO/TS16949 quality management system,and exported to more than 100 countries, inclucing Europe, Middle East, Southeast Asia,etc. Long term cooperation with big buyers and famous brands had been established in Germany, USA, Turkey and other countries.
First of all, independent suspension means that the suspension of each wheel is independent and independent of other wheel suspensions. The independent suspensions are commonly used in the form of double wishbone, McPherson, and multi-link. The cost of the independent suspension is relatively high, and the difficulty of training is relatively large compared to the non-independent suspension. However, due to its inherent structural advantages, the independent suspension can perform better in terms of mobility and comfort.
The multi-link independent suspension generally has a complicated structure, and the rear suspension has four or five links, and the five links are widely used. Because of the complex structure and the durability of the independent suspension, the multi-link independent suspension will remain invariable and not displaced, so there will be great differences in the structure and material selection, thus also affecting the comfort of the suspension. degree. In addition, the site training can also affect the degree of soft and hard, probably affecting about 20%.
Non-independent suspensions are generally used as rear suspensions for automobiles because they interact with each other between their two wheels. Although the non-independent suspension is not dominant in structure, its simple structure can minimize the impact on the interior space of the vehicle, and the cost is low, and the vehicle enterprise often uses it on the economical trolley.
Suspension softness is closely related to the hard and soft parts of front and rear shock absorbers, springs and connecting bushings, and has no direct or obvious connection with independent suspensions and non-independent suspensions. Some non-independent suspensions are softer if the spring parts are softer. The suspension is also harder if the spring of the independent suspension is harder. The harder part is related to the chassis training and the seat. Independently suspended cars are not necessarily sitting soft, and non-independently suspended cars are particularly soft and comfortable. Independent suspension has its own advantages and can be seen when it passes through the pit.
In addition, there is a very important point to adjust. A well-tuned non-independent suspension is able to catch up with the independent suspension in various performance indicators. The French car is a very good example. Therefore, when we look at the car, we must not only look at the structure of the suspension, but also actually drive to feel the level of training of the engineers on the suspension.
All in all, a good chassis is inseparable from a good suspension, and a good suspension is not enough to support a good chassis. In addition to the suspension, there are many factors that affect the performance of the chassis, such as the tuning of the steering system, the tuning of the brake system, and so on. Therefore, in addition to the structure and training of the suspension, the cooperation between the other components is also essential.
