In the hot topic of the riders, the topic of engine, transmission and suspension has always been a topic of constant discussion in the car circle, and was asked among the 100,000 to 150,000-class compact family cars that Chinese consumers consume the most. The question most is how about the suspension of this car? Can the "board" be bought? And so on, today, Mr. Qi talked about the suspension selection problem of compact family car! Speaking of car suspension, many people may not understand. In fact, the car chassis and car suspension that we usually say are basically car suspension. Simply put, one end is fixed on the body and the other end is linked to the wheel. The middle part is called the suspension. It looks like several metal rods plus springs and a compressible damping tube. The driving characteristics, overall comfort and sports performance of the vehicle are mostly from the suspension, so the suspension is very important. Mr. Qi talks about the types of suspensions for the 100,000 to 150,000 compact family car. Suspension type of 100,000 to 150,000 class compact family car Careful observation of the configuration table or familiar with the car's riders will find that this level of family car is equipped with a variety of suspensions, the front and rear suspension of a car is different. In fact, this type of model is equipped with a variety of suspensions, many high-end forms are not equipped, the front suspension is basically equipped with a MacPherson-type front suspension. Mainly the McPherson-type front suspension is relatively mature, and the structure is compact, which can save a lot of space for the engine compartment. Here is not to repeat, mainly talk about the rear suspension that most people ask. This type of rear suspension for family cars can be really varied, multi-link independent suspension, torsion beam non-independent suspension, leaf spring suspension and so on. At present, the major automotive manufacturers have a total of two types of rear suspension loading trends, namely multi-link independent suspension and torsion beam non-independent suspension. Many riders have a torsion beam type of non-independent suspension called "board suspension", and the controversy has arisen. Let's talk about these two. Independent rear suspension analysis The multi-link form of the rear suspension is generally called an independent suspension. The detailed structure can be seen from the following diagram, and the structure of the following diagram is only one of them, although it is called multi-link, but the change There are many forms, including the connection form and position of the connecting rod, and the installation form of the damping cylinder and the spring are very different. The multi-link suspension system has many advantages. Since the rear two wheels can move up and down completely independently, the comfort is superior to the torsion beam rear suspension. Since the multi-link suspension has more adjustable parameters, it is easy to calibrate the suspension motion orientation with more motion characteristics, so the vehicle handling performance also has certain advantages. These two aspects are more important in evaluating whether a suspension is occupied by high quality. These two parameters are also important when developing suspensions. However, the multi-link type rear suspension also has disadvantages, and the price is higher than that of the rear suspension in the form of a torsion beam. On the other hand, the multi-link rear suspension has a relatively large space because of its complicated structure. Because the car exhaust system generally crosses the rear suspension, the multi-link rear suspension will also affect the space and comfort of the rear row and the space of the trunk to some extent. Having talked so much, let's talk about the torsion beam non-independent suspension of the "board". Non-independent rear suspension analysis The rear suspension in the form of a torsion beam is mostly referred to as a non-independent rear suspension. The detailed structure is also shown in the following figure. The form of the rear suspension in the form of a torsion beam is almost always in this form. Although this suspension is called a non-independent rear suspension, it is not really non-independent. This form is semi-independent or more appropriate. When the suspension is in operation, the left and right suspensions can be operated relatively independently by the torsion of the torsion beam in the middle. This independent work is also relative, so there is some difference in the comfort of the suspension in the form of a torsion beam compared to the multi-link form of the rear suspension. In terms of maneuverability, due to the structure of the rear suspension in the form of a torsion beam, the performance of the rear suspension is not as good as that of the multi-link type. However, the suspension system in the form of a torsion beam has many advantages, and the price advantage is the most important advantage for the enterprise. For the consumer, the torsion beam can give more space to the bottom of the car's rear floor. The space utilization of the exhaust system's rear end, muffler and secondary three-way catalyst can be more reasonable, so most of them are equipped with torsion beams. The rear rear space and the trunk space of the rear suspension of the form have better performance. What kind of suspension is chosen? The characteristics of the two rear suspensions are separately interpreted. There may be some consumers who still have some difficulty in understanding, so simply summarize them. Most of the multi-link form of the independent suspension has better maneuverability and comfort than the torsion beam type of non-independent suspension, but the space performance is not very good. So if we really want to choose a car because of the suspension system, what kind of suspension should we choose? Mr. Qi suggested that in the compact household models of 100,000 to 150,000 yuan, if you choose the car because of the choice of suspension, you still choose the non-independent suspension of the torsion beam. First of all, although the multi-link suspension is more comfortable than the suspension in the form of torsion beam, the cost of selecting the 100,000 to 150,000 compact family car due to the damping cylinder and other connectors is not suitable for the cost of training. Too high, so the specific performance of the two suspension comforts on this level of the car is not much different, and can not cause the user to perceive. This is only one aspect. On the other hand, it is maneuverability. The multi-link suspension is only more extreme than the torsion beam suspension, and the family car can drive to the limit control or close to the limit control. It can only stay in theory better, so there is no more meaning. For the consumer to perceive the larger spatial aspect of the car, the suspension in the form of a torsion beam is more advantageous. However, not all rear suspensions in the form of torsion beams have advantages, as some models are equipped with two rear suspensions on the high and low models, the main reason is to reduce costs and differentiate the vehicle configuration. Vehicles equipped with two types of rear suspensions are designed with multi-link rear suspension in mind, so there is no advantage in space performance. Consumers facing this type of vehicle should also pay attention to this. SHENZHEN CHONDEKUAI TECHNOLOGY CO.LTD , https://www.szfourinone.com
