1. Introduction: The chassis in the era of oil trucks is troubled
For the majority of car consumers, chassis performance has always been one of the important indicators to judge the quality of a model. A comfortable and smooth driving experience often touches the hearts of consumers. However, in the era of traditional oil vehicles, this seemingly simple chassis problem has been plaguing the entire automotive industry.
The main reason for this lies in the complexity of the internal structure of the oil truck. The placement of important components such as engines, gearboxes, and fuel tanks often affects the weight distribution and centroid height of the vehicle, which brings many challenges to chassis tuning. Even some well-known car companies need to spend a lot of manpower and material resources to repeatedly debug in order to finally ensure that the chassis reaches the ideal state.
But with the advent of the electric car era, this problem seems to have disappeared. Many electric vehicles worth more than 200,000 yuan can actually have a chassis texture comparable to that of a million-level luxury car? Some people in the industry have conducted in-depth explorations and uncovered the mystery behind this.
Second, the innate advantages of trams
For the chassis problem in the era of oil vehicles, industry insiders believe that the reason why trams can easily solve this problem lies in their own inherent advantages.
In contrast, the internal structure of the tram is much simpler. Vital components such as the engine and gearbox have been replaced by electric motors and battery packs, which have become more flexible in their weight distribution and placement.
In the case of BMW, for example, when designing the chassis, the company often carefully adjusts the weight ratio of the front and rear axles to 50:50 to ensure steering balance and handling. But for oil trucks, this balance is very difficult, because the position of important components such as the engine and gearbox is very limited.
In the case of trams, this problem is solved. The placement of the motor and battery pack can be more freely, and the setting of the front trunk makes the weight distribution of the vehicle more balanced. At the same time, a large battery is placed at the bottom of the body, which is also like a "Dinghaishen needle", which greatly improves the stability and balance of the vehicle.
It can be said that this innate structural advantage gives the tram a natural advantage in chassis design, which greatly reduces the difficulty of tuning. In contrast, it will undoubtedly take more effort to achieve similar chassis performance in a petrol car.
3. High torsional stiffness of the tram
Another important factor in solving the problem of the tram chassis is the increase in torsional stiffness.
If torsional stiffness is insufficient, the body will twist and deform during cornering, causing relative motion between chassis components, resulting in noise, vibration and roughness. On the contrary, if the torsional rigidity is high enough, the body will be able to move as a single unit, and the overall driving experience will be smoother and smoother.
It is worth mentioning that in the era of oil vehicles, the models that can reach 40,000N·m/° torsional rigidity are often some million-level luxury models. However, in the era of electric cars, even if it is a model of more than 200,000 yuan, the torsional rigidity can easily reach this standard.
This outstanding performance is mainly due to the optimization of the chassis structure of the tram. In order to protect the battery, a key component, the chassis stiffness of the tram is often greatly improved, which directly leads to an increase in torsional stiffness.
It can be said that this feature further strengthens the advantages of the electric car in terms of chassis performance. When driving an electric car, consumers can feel the excellent performance of the vehicle's handling and stability, even in rough road conditions, and maintain an excellent driving experience.
Fourth, the configuration of the tram regardless of the cost
In addition, another feature of the electric car era is the significant increase in vehicle configuration.
In the era of oil trucks, even some mid-to-high-end models rarely adopt the advanced suspension design of the front double wishbone and the rear five-link link. Although this structure can improve the performance of the chassis, the cost is high, and it can often only be applied to some luxury models.
But by the time of the tram, things had changed dramatically. With the exception of a few special models, almost all electric vehicles use an advanced suspension scheme with double wishbones at the front and a five-link link at the rear.
Behind this change, it is mainly due to the continuous improvement of the tram industry chain and the rise of independent brands. In contrast, some international car companies are often not actively investing in the field of electric vehicles, and are even playing the old routine of "five killer features of Asian dragons".
However, for dynamic domestic brands, they pay more attention to the improvement of product strength, and have made great efforts in chassis configuration and performance. Such dedication is naturally reflected in the excellent performance of the train.
5. Summary
To sum up, the reason why trams can easily solve the chassis problems in the era of traditional oil vehicles is mainly due to three factors:
First of all, the simplicity of the internal structure of the tram makes its weight distribution more balanced, which greatly improves the stability and handling of the vehicle. In contrast, oil trucks have always had many problems in this regard.
Secondly, the advantages of the tram in terms of chassis stiffness are also obvious. In order to protect the critical battery components, the overall stiffness of the tram has been greatly improved, which directly leads to a significant improvement in torsional stiffness. This undoubtedly greatly enhances the driving experience of the tram.
Finally, the configuration level of the electric car era regardless of cost is also one of the important reasons why it can easily solve chassis problems. A tram of more than 200,000 yuan can have a suspension design and chassis configuration comparable to that of a million-dollar luxury car, which was unimaginable in the past. 6. Further prospects for the problem of tram chassis
Looking to the future, with the continuous advancement of electric vehicle technology, it is believed that its advantages in chassis performance will be further highlighted.
First of all, as battery technology continues to innovate, the overall weight and center of gravity height of electric vehicles are expected to be further reduced. This not only further improves the stability and handling of the vehicle, but also opens up more room for optimization in the chassis design.
At the same time, the further optimization of the motor and electronic control system in the future will also bring about the continuous improvement of the power performance of the tram. This is a big plus for the chassis, as the more powerful drive system provides better support for the chassis.
In addition, with the increasing maturity of vehicle intelligent technology, trams will also achieve breakthroughs in chassis control in the future. Through the synergy of on-board sensors and intelligent algorithms, the tram can realize real-time monitoring and accurate adjustment of the chassis status, further enhancing driving comfort and safety.
It can be said that the continuous upgrading of these technologies will further strengthen the dominant position of electric vehicles in terms of chassis performance. I believe that in the near future, we will be able to see trams emerge in more market segments and become the first choice of consumers.
VII. Conclusion
In general, the reason why the tram can easily solve the chassis problems in the era of traditional oil vehicles lies in its own unique internal structure and technical advantages. From the balanced weight distribution, increased torsional rigidity, to the popularization of high-end equipment, the synergy of these factors has made a qualitative leap in the chassis performance of the tram.
In contrast, chassis tuning in the era of oil trucks has always been a thorny problem, requiring car companies to invest a lot of manpower and material resources to barely meet it. In the age of the tram, this problem has largely disappeared.
To a certain extent, the chassis advantage of trams also reflects the profound changes that are taking place in the domestic automobile industry. The rise of independent brands is driving technological progress and product innovation across the industry, bringing consumers a new driving experience.
In the future, with the continuous improvement of tram technology, it is believed that its advantages in chassis performance will be further expanded. It is believed that in the near future, trams will become the preferred mode of travel for consumers, injecting new vitality into the mainland automobile industry.
