In the past, air suspensions would usually only appear in high-end models that cost half a million or six hundred thousand and more. As for the reason, it is actually the high cost. Air suspension has high and low, soft and hard adjustment capabilities, which can help the vehicle significantly improve comfort and handling, but its increased cost is also significant, and the maintenance cost is higher, so the slightly lower price model will not provide this configuration.
However, when domestic cars entered the high-end market, this status quo has changed. Taking Lantu FREE as an example, although it is only priced at 300,000 levels, it gives air suspension with high luxury attributes, while models at the same price are rarely equipped with this equipment. In this regard, many people also questioned that the cost of air suspension is so high, how does Lan Tu hold it? Did you cut corners in other aspects of the suspension system? So today we're going to talk about why it can.
Before talking about the FREE air suspension, let's first understand its suspension structure. The LANDOU FREE front suspension is a double wishbone independent suspension, and the rear suspension is a multi-link independent suspension. In terms of materials, the main control arm and bearing seat of the front overhang are made of aluminum alloy, and the rear overhang of the rear wheel inclination control arm, integrated connecting rod and other components are made of aluminum alloy. The overall material and lightweight are in place, and it can even be said that the Landu FREE is comparable to the 500,000-level luxury SUV in the chassis.
(Academician of Chinese Academy of Engineering: Guo Konghui)
Back to the air suspension itself, the air suspension carried by Lantu FREE originates from Konghui Technology Company, and the core team of Konghui Technology is composed of Guo Konghui, an academician of the Chinese Academy of Engineering, and the members of the technical research and development, which is an authentic independent enterprise, and its core technology is mastered by our own people, including the spring packaging inside the air suspension, oil pump, control valve, electronic control system, etc., which are also independent production. Therefore, Lantu Automobile can purchase air suspension in a more cost-effective way, thereby reducing the cost of the vehicle, and also breaking the technical blockade and suppression of foreign manufacturers on their own brands in this regard.
Of course, some people may think that the domestic air suspension is not as good as others, but it should be known that Academician Guo Konghui began to develop air suspension as early as the 1950s and 1960s, and its products have been first applied to commercial vehicles and other fields, which have been tested by the market, and the products have also undergone strict reliability and long-distance testing of real vehicles, and the actual performance is comparable to the performance of similar foreign products. Taking Lantu FREE as an example, the driver can switch the driving mode next to the gear, adjust the body height, and match it with a total of 5 driving modes: economy/comfort/high-energy/outing/custom.
Among them, in the economy / comfort mode, the chassis height of Landu FREE can be adjusted to 163mm, if the welcome mode function is turned on, then when the key is sensed close to the vehicle, the air suspension of Landu FREE will automatically reduce the chassis height to 113mm, so that the elderly and children can get on and off; when the speed is increased to more than 5km/h, the vehicle will return to the normal height to ensure passability.
When the vehicle switches to high-energy mode, the chassis height of the Landu FREE will be reduced to 133mm, and the suspension at this time will be tougher than in the economic/comfortable state, and the more obvious feature is that the roll suppression effect is better when changing lanes at high speed and continuous corners, and the body is more flexible. In this mode, with the strong performance of breaking 100 in only 4.5 seconds, the stability of running mountain roads or highway conditions can be guaranteed.
As for the outing mode, the chassis height of the Landu FREE will rise to 213mm, and the softness of the suspension will be closer to the comfort mode. After raising the chassis, the overall passability will be easier when dealing with complex road conditions such as continuous potholes and stepped sections. In the previous air suspension challenge, Lantu FREE faced challenges such as step road, sleeper road, bump road and so on, and everyone was also there for all to see.
Editor's comments: Through the interpretation of the air suspension and dynamic performance of Lantu FREE, it is not difficult to find that it has not "cut corners" in the chassis, but mainly adopts the air suspension independently developed and produced to control the cost of the vehicle. In terms of actual performance, this air suspension is not a "flower frame", with its Lantu FREE, it can indeed give the driver a good handling and comfort experience, such as the right balance between the Audi Q5L and the BMW X3. If it is the comfort of running at home, and want to drive alone when the speed and passion, then this Lantu FREE is the first choice for 300,000 levels, of course, to choose the Lantu FREE with air suspension, this is the soul of the whole car.
