Continental Group upgrades air spring lightweight technology

Continental’s latest lightweight technology is the use of composite materials for pistons in air spring systems, which makes the product lighter while maintaining the reliability of the spring.

The technology company Continental is one of the first suppliers of air spring systems for the Chinese commercial vehicle market, with leading air spring technology to help develop commercial vehicle technology. “Strict implementation of the national standard GB/1589-2016 has brought about tremendous changes to the entire commercial vehicle industry, taking commercial vehicles to a new level of attention to lightweight. In addition to advanced lightweight technology, Continental further improved its formula. The high temperature resistance of air springs has been improved; digital technology combined with products can provide customers with advanced online weighing systems,” said Wang Lianping, China’s major account manager for Continental Air Spring Systems. At the upcoming 2019 Beijing International Road Transport, Urban Bus and Parts Exhibition (May F1, Booth F46), which will be held from May 29th to 31st, Continental will showcase applications and buses for the industry and customers. The results of technological developments on road transport vehicles such as trailers and new energy buses.

Continental Group upgrades air spring lightweight technology

Due to the strict implementation of the national standard GB/1589-2016, the overload problem has been effectively controlled. The realization of sustainable profitability through efficiency improvement rather than overloading has become the basic consensus of the commercial vehicle terminal customer circle. Therefore, the lightweight requirements of heavy-duty truck operating vehicles have never been noticed. The demand for lightweight energy for new energy buses is also urgent.

In practical applications, air springs have many significant advantages over leaf springs: first, air springs use the compressibility of air to achieve their spring action. Air springs are naturally beneficial to the lightweight design of vehicles, thus effectively reducing fuel consumption and improving Payload, saving on operating costs. Secondly, vehicles equipped with air springs provide good vibration isolation by virtue of their low natural frequency and substantially constant over the full load during travel, significantly reducing vehicle impact and damage to the road surface while reducing tire wear and protecting the vehicle.

Continental’s latest lightweight technology is the use of composite materials for pistons in air spring systems, which makes the product lighter while maintaining the reliability of the spring. Customers only need to follow the original installation method. This is a lightweight technology that is only light (light weight) without loss (spring reliability). The secret is that the piston of the air spring provides a full additional air chamber and can have a buffer block support structure. This is very different from the first generation of lightweight technology: only providing a lightweight piston without an auxiliary air chamber can not effectively reduce the natural frequency of the air spring. “This latest lightweight technology has been supplied in bulk in Europe, and it has also received strong demand from domestic customers. The project is in progress. For example, the weight reduction effect of one product is obvious, and the configuration of single-bridge 4 airbags can be Losing more than 13 kg, equivalent to more than 30% weight reduction of the air spring system.” Wang Lianping said.

Material optimization for high heat transport environment

Continental’s air springs are equipped with two rubber compounds to cope with different environments, namely standard natural rubber substrates and high-grade neoprene substrates. The former has good cold resistance and the latter is resistant to heat and aging. better. With the advancement of technology, the upgrading of emission standards, and the need for air-spring products with better heat resistance in hot regions, Continental Group has further improved the fatigue life at high temperatures by further optimizing the compound formulation of neoprene substrates. High Temp Level I air spring, the new rubber product airbag can double the test fatigue life under the temperature of 80 ° C, and has entered the mass production stage. More than that, the company is developing a next-generation, high-temperature formula for the High Temp Level II at 100°C.

Advanced online weighing system

Commercial vehicles, as production tools, require the most efficient means of transportation. Continental helps customers achieve this goal. The Continental Group’s online weighing system enables real-time load display and takes full advantage of the vehicle’s load capacity. When the vehicle is overloaded, the online weighing system will immediately issue an overload warning to the user to help the user comply with laws and regulations, and at the same time use the carrying capacity within the allowable range to help strengthen road safety and protect the road as an important infrastructure.
