1 A model of differentiated configuration, air suspension is expected to enter the explosive period

At present, the share of independent brands continues to increase, and differentiated configuration has become one of the core competitiveness of independent brand product strength. From the perspective of the market share of more than 150,000 yuan, the share of independent brands before 2021 mainly hovered around 11%, and in the first half of 2021, the share has increased to more than 16%. Judging from the main models newly released at the 2021 Guangzhou Auto Show, independent brands and car-making forces are leading joint venture brands in both intelligent configuration and technology configuration: 1) In terms of intelligent driving functions, including the launch of intelligent driving in high-speed road sections, as well as the application of intelligent driving hardware such as cameras, millimeter-wave radar, lidar and higher computing chips. 2) In terms of technology configuration, the 19 main models launched by the independent brands (including new forces, independent new high-end and independent brands) launched at the 2021 Guangzhou Auto Show have reached 7 models, 6 air suspensions, and 6 intelligent headlights.

Taking the air suspension as an example, the independent rise, the luxury quality gradually sinks, and its proportion as a high-end configuration is expected to increase. Since 2017, WEIO has successively launched ES8 and ES6, the air suspension is first installed in models below 500,000 or even 400,000 yuan, and in 2021, Dongfeng Lantu FREE and Geely Extreme Kr 001 continue to sink the price of air suspension models to less than 300,000 yuan (the entry price of the extreme krypton 001 before the order on July 31, 2021 is 266,000, and the price after counting the air suspension option is 286,000 yuan). In 2021, China's passenger car air suspension sales reached about 460,000 units, accounting for the penetration of the passenger car market from 1.27% in 2018 to 2.2%, accounting for more than 250,000 yuan of model market penetration reached about 9%. (Note: Models with a statistical caliber with air suspension standard, considering the option, the penetration rate is higher).

Consumption continues to upgrade, high-end intelligent electric acceleration air suspension applications. In recent years, the trend of automobile consumption upgrading in mainland China has been remarkable, with the increase in purchasing power + the increase in the proportion of purchases, the average purchase price of passenger cars has continued to rise, especially the proportion of sales of high-end models of more than 250,000 yuan has increased significantly, from 17.3% in 2018 to 23.8% in 2021, and the air suspension has also entered the configuration list of more people. On the other hand, the new forces are rising rapidly, under the brand positioning of high-end intelligent electric vehicles, the acceptance of emerging, high-end configurations is higher, more willing to use, such as Weilai Automobile, the new forces are expected to pull the trend of air suspension consumption, and more car companies are expected to appear in the future to carry air suspension, such as Hongqi, Extreme Krypton, Lantu, etc. have become the forerunners after Weilai.

Market space: The air suspension scale of passenger cars is expected to reach 18.7 billion yuan in 2025

Assumption: Under the consumption upgrade, it is expected that the market sales and share of passenger cars of more than 250,000 yuan are expected to continue to increase, and more air suspension demand will be born; in the future, localization and scale will bring about a decline in unit prices, which is more convenient for the popularization of the air suspension market. According to calculations, by 2025, the continental air suspension passenger car market size will be 18.70 billion yuan, with a compound growth rate of 41.8%.

2 How difficult is the air suspension?

In the air suspension, the internal components include the front air struts, rear air springs, compressors, valve blocks, pressure storage tanks, sensors and electronic control units, with the front air struts in the front wheels, the electronic control unit in the center of the body, and the rest concentrated in the rear of the vehicle. In the operation, there is an air path and a data path: in the air path, the compressor compresses the air, through the valve block to distribute the compressed air to the air pillar, the rear air spring, the pressure storage tank, when the compressor can not meet the front and rear springs, the compressed air in the storage tank will be distributed to the front air pillar and the rear air spring; in the data path, the sensor completes the data collection Through the electronic control unit processing, the control of the front air pillar, rear air spring, compressor, valve block is completed. Due to the high dependence of body stability on air suspension, the stability requirements for the development and design of air suspension systems, electronic control systems and rubber parts are higher in the design and use of air suspension.

System integration: complex development, cumbersome inspection specifications

The development of air suspension systems is complex and requires the combined action of multiple components. According to the "Air Suspension Design Code" implemented by the Ministry of Industry and Information Technology in 2010, there are clear provisions on the air suspension design and development process: in the design and development process of air suspension, it is necessary to complete the calculation of roll stiffness and roll angle, air suspension stiffness, height control valve, motion up and down limit, limit valve calculation, and meet the parameter standards in the air suspension design code; it is necessary to complete the selection of various die casting parts such as guide mechanism, shock absorber, rear stabilizer rod, rear guide arm, thrust rod, etc.; caE analysis of the bearing parts, and finally in Under the premise of ensuring the strength of the parts, reduce the weight of the air suspension and optimize the air suspension structure.

The air suspension acceptance test specification is complex, and the multi-dimensional test ensures the safety of the air suspension on the car. According to the "Air Suspension Design Code" implemented by the Ministry of Industry and Information Technology in 2010, the testing methods and test methods that need to be completed in the acceptance stage of air suspension design are clarified: it is necessary to review from multiple dimensions such as scheme, drawings and physical objects; it is necessary to conduct acceptance tests on the smoothness, stability, strength of parts and components, motion coordination and other dimensions of the suspension system; and it is necessary to complete a variety of multiple acceptance tests.

Electronic control system: precise control improves comfort, and the barriers of electronic control terminals are clear

The electronic control system has a complex structure and high algorithm requirements. In the electronic control system of air suspension, the electronic control unit needs to collect the data information emitted by a variety of sensors to complete the processing and then realize the precise control of the components, and the software side needs to carry out multi-threaded high-level operations, and the algorithm development is more difficult. And because the various components of the air suspension are spread throughout the various positions of the body, the pipeline is also relatively complex, and the requirements for transmission speed and control accuracy are high.

The need for comfort has led to an upgrade in the algorithm of the air suspension electronic control system. For passenger cars, comfort is an important indicator for users to measure the quality of the driving experience. In the process of rapid acceleration and rapid deceleration of the car, because the self-propelled cruise (ACC) system will brake urgently, the phenomenon of the vehicle "looking up" or "looking down" occurs. At this time, the air suspension electronic control system changes the front and rear heights by pumping and deflating the front and rear springs, offsetting the additional vertical force generated by the self-propelled cruise system, thereby improving the comfort of the vehicle. In this process, the electronic control system needs to be connected with more sensors, the electronic control unit data processing difficulty increases, and the algorithm ability and development difficulty are upgraded again.

Automotive Air Suspension Industry Research: How to View the Opportunity of Localization of Air Suspension Systems?

As one of the terminals of the electronic control system, the air supply unit has obvious industrial barriers with high technical difficulty. At the end of the electronic control system are the valve block and the air supply unit. In the air suspension system, the operation of pressing in and releasing air is realized by the control and regulation of the valve block and the air supply unit by the electronic control system, and the air flow direction is controlled. The industry barriers to the air supply unit are obvious: (1) Because the compressor needs to quickly reach a pressure of 15-20 bar in a short period of time, the friction of the internal motor rotor, cylinder block and other parts needs to be extremely small to ensure that the compressor will not overheat. (2) A large number of rubber and metal parts in the suspension system need to ensure that the air pressed into the compressor is absolutely dry. (3) When facing the aftermarket, it is necessary to ensure the ease of operation of the air supply unit. In summary, the air supply unit needs to have a strong drying capacity, smaller heat production, smaller volume and completeness, more technical difficulties, and higher production requirements.

Rubber airbags: the complex life of the force is high, and the formulation and process form barriers

Rubber parts are subject to complex forces, and there are many deformation factors that change, which have a great impact on the stability of the suspension. In the process of automobile movement, rubber parts are subjected to forces and moments in multiple directions, and there is a possibility of deformation in various directions in space, and are affected by the installation position, structural shape, whether there are metal constraints and other aspects, and the deformation of each direction will be coupled. Due to the complex deformation situation and many influencing factors, the deformation of rubber parts brings great challenges to the adjustment and control of wheel attitude and suspension stability. For suspension suppliers, it is necessary to control the deformation of the rubber parts to ensure that the suspension can obtain the elastic kinematic characteristics required by the automaker.

Rubber parts require complex requirements, functional requirements are numerous and precise. The rough structure of the rubber gas spring is a layer of calendered rubber lining, a layer of reinforced skeleton layer, and a layer of calendered rubber outer layer of glue. Rubber parts need to be maintenance and lubrication, no need for internal operation of the rod or piston, there is a certain bending angle, easy installation, low cost, high degree of control and precision, and to achieve anti-resonance, noise reduction and other functions, complex functions, a variety of needs, the need for the company has a strong R & D capabilities. The transportation and preservation environment of rubber parts is special, and it is necessary to avoid sharp objects, avoid direct sunlight, avoid contact with organic matter, and require the company to have strong warehousing and logistics capabilities.

The durability of the rubber part determines the service life of the air suspension. According to the information of the automobile maintenance technology network, the air suspension problem is concentrated on the air bag leakage and pipe rupture, due to the long use time or the moisture in the air enters the inside of the system, cracked rubber may cause the air suspension to fail. In addition to airbags and pipelines, rubber parts between suspension arms are also parts that are prone to aging due to factors such as complex stress, frequent use, and high working strength. The rubber parts of the air suspension, the durability of which will determine the life of the air suspension. (Source: Future Think Tank)

Automotive Air Suspension Industry Research: How to View the Opportunity of Localization of Air Suspension Systems?

The main products of Zhongding Co., Ltd. in air suspension are air storage tanks, air supply units and air suspension assemblies. The air storage tank and air supply unit are the company's own technology self-produced products, and the air suspension assembly needs to be assembled after purchasing the remaining parts. Among them, the air supply unit is the most technically difficult component in the entire air suspension module, and the performance of the air supply unit will directly affect the mechanical performance of the air suspension system.

After the localization landed, Zhongding co., Ltd. received more than 2.4 billion orders, and the project life cycle was 4-10 years. From the perspective of the value of the order product bicycle, the price of the air storage tank parts bicycle is 400-500 yuan, the price of the air supply unit assembly bicycle is 1600-1800 yuan, and the price of the air suspension assembly bicycle is more than 4000 yuan.

Due to the high technical difficulty of the air supply unit, the industry barriers are more obvious, and the more well-known suppliers in the industry are only Continental, ZF's WABCO and AMK under Zhongding Co., Ltd. Other domestic suppliers are still difficult to achieve a qualitative breakthrough in the air supply unit in a short period of time, and Zhongding Shares has maintained its technical advantages and product leadership in the market for a period of time.
