As Tesla's Grok large model takes the reins, and Li Xiang L6's air suspension adjusts the vehicle's stance seamlessly, an intelligent transportation revolution is extending its reach from the driver's seat to the chassis system.

In this emerging battleground where L3 penetration is anticipated to hit 85%, a Chinese automotive parts giant is leveraging 15.2 billion in air suspension orders as a pivot to drive its expansion from intelligent chassis systems to humanoid robots.

With revenues totaling 18.8 billion and a heritage as one of the top three global air suspension players, Zhongding shares is undergoing a remarkable transformation from a traditional manufacturer to a front-runner in AI liquid cooling and humanoid reducers.

The "brain of the chassis" built on 15.2 billion orders.

Zhongding shares' position as a leader in intelligent chassis systems began with the acquisition of Germany's AMK in 2016.

By acquiring AMK, Zhongding gained access to air supply unit technology, localized production, and cost reductions of 60%. With 15.2 billion orders in hand and a global market share of 23%, the company is solidifying its position.

Three keys to technological breakthroughs.

1. Core component advancement: Integrated compressor noise reduced to <45dB (industry average: 65dB).

2. Control algorithm dominance: Millisecond-level response to road bumps (five times faster than traditional hydraulic systems).

3. Cost reconstruction: Localized production slashes the unit price of air suspension systems from 12,000 yuan to 8,000 yuan.

The VLA model revolution in 2025 has elevated air suspension from a mere "comfort configuration" to an "intelligent actuator." It autonomously lifts the vehicle body over bumps and actively adjusts support during high-speed cornering, with a 100% installation rate on the Li Xiang L6.

"Air suspension is the knee of a smart car, and AMK has enabled us to master the secrets of flexion and extension," said Chairman Xia Yingsong, emphasizing the strategic value of the acquisition. With 32 models, including the Mercedes-Benz EQE and XPeng G9, secured, revenues from this business are projected to exceed 5 billion yuan in 2025.

Spreading Wings: A 100 Billion Layout in Lightweight and Thermal Management.

As the air suspension business surges, Zhongding's other two aces are breaking through growth ceilings.

The "weight loss expert" for new energy vehicles. The ball joint hinge assembly boasts a fatigue life exceeding 5 million cycles (three times the national standard), and the Mexican factory supplies chassis for Tesla's Cybertruck, with revenues expected to reach 2.518 billion yuan in 2024 (a 219% increase over four years).

From the automotive era to the AI liquid cooling era.

The most ingenious aspect is technology reuse: Automotive-grade sealing technology transformed into a server liquid cooling leak prevention solution; air suspension precision valves becoming liquid cooling flow control modules. In 2024, the thermal management business contributed 3.6 billion yuan in revenues, and AI liquid cooling is poised to become the next growth driver.

Robot Surprise Attack: The "Triple Jump" Behind the 1 Billion Bet.

While the industry is still observing the commercialization of humanoid robots, Zhongding has already launched a competitive push.

Robot strategy advancement timeline.

The dual confidence of dimensional reduction strikes, from the grinding precision of 0.001mm for automotive ball joints to the tooth profile processing of harmonic reducers, AMK motor control technology, and robot joint servo drives. Collaborating with Wuzhou Xinchun to build a gear supply chain and jointly developing dexterous hands with Zhongqing Robotics.

The first batch of harmonic reducers has been sampled to UBTech, and news of a yield rate exceeding 92% indicates an impending disruption of the industry's cost structure.

A qualitative change signal with a net profit of 400 million yuan doubling sequentially. The explosion of a net profit of 403 million yuan in Q1 2025 (a sequential increase of 101%) reveals the profound transformation results.

Triple verification of growth quality.

1. Gross margin leap: 28.7% (a year-on-year increase of 3.2 percentage points).

2. Order accumulation: Contract liabilities surged to 830 million yuan (a year-on-year increase of 180%).

3. Ample cash flow: Net operating cash flow of 620 million yuan (sufficient to cover robot investments).

The business structure is healthier. Revenue composition in Q1 2025: Intelligent chassis 42%, thermal management 31%, lightweight 22%, and others 5%. With the expansion of air suspension capacity and the rise of humanoid robots, Xia Yingsong's declaration of "net profit exceeding 1.5 billion yuan in 2025" is gradually becoming a reality.

An Ecological Leap from Car Manufacturing to Humanoid Creation.

Zhongding's ultimate ambition lies in the convergence of intelligent transportation and robot technology.

The golden triangle of technological synergy.

1. Air suspension actuator, robot joint module.

2. Automotive-grade liquid cooling, servo motor heat dissipation.

3. Chassis control algorithm, bipedal balance system.

As Tesla's Optimus and Cybertruck share a production line, and Zhongding's harmonic reducers are installed in both humanoid robots and intelligent chassis, this evolution from "empowering cars" to "creating humans" transcends the traditional boundaries of auto parts suppliers.

China's Wisdom in the Trillion-Level Intelligent Motion Industry.

In the smart factory in Ningguo, Anhui, six-axis robotic arms are loading air suspension compressors into Mercedes containers, while the adjacent workshop is conducting life tests on harmonic reducers. These precision components, destined for Germany and integration into humanoid machines, are becoming the "universal language" of intelligent motion control.

From the technological counterattack of acquiring AMK to the cost revolution of air suspension localization, from the invisible champion of automotive lightweighting to the breakthrough player in robot joints, Zhongding shares' path of advancement epitomizes the ultimate law of Chinese manufacturing.

In the high-end electromechanical field, vertical deepening builds technical barriers, and horizontal migration ignites exponential growth. When Xia Yingsong announced, "We want humanoid robots to use automotive-grade reliable components," the ambition of this enterprise surpassed the industry itself, becoming the foundational architect of intelligent motion control.

With 15.2 billion air suspension orders continuously being fulfilled and the 1 billion robot base put into production, Zhongding shares' intelligent trilogy has reached its climax. In this grand narrative of a 200 billion air suspension market and millions of humanoid robots, the transformation steps of this automotive veteran are writing the most resounding footnote for Chinese intelligent manufacturing.
