New breakthroughs in intelligent and electric drive crankshaft, sensor and gear technologies

2025-04-22

Shanghai, April 22, 2025 - AutoTech Expo 2025, the world's leading automotive parts event, grandly opened today at the National Exhibition and Convention Center (Shanghai). This exhibition, themed "Intelligent Drive for the Future · Green Mobility", focuses on core components such as crankshafts, sensors, gears, filters and bumps, attracting over 800 exhibitors from more than 40 countries. Showcase the latest technological achievements and industry trends.

1.Crankshaft innovation in the era of electrification
With the continuous increase in the market share of hybrid and pure electric models, crankshaft technology has undergone a major upgrade. Many enterprises have launched carbon fiber reinforced composite material crankshafts, which are 40% lighter than traditional steel crankshafts and 20% stronger, significantly enhancing the efficiency of new energy engines. In addition, the integrated crankshaft-motor design becomes the focus, which can reduce energy loss and is suitable for the next generation of extended-range electric vehicles.

2. Intelligent sensors: The core support for autonomous driving
In the high-precision Sensor exhibition area, manufacturers showcased a new generation of multi-in-one intelligent sensing systems, which can monitor engine operating conditions, emission data and the health status of components in real time, and achieve cloud diagnosis through the Internet of Vehicles (V2X).

AI vision sensor: Used for monitoring the condition of autonomous driving gearboxes and providing early warnings of wear.

Hydrogen energy pressure sensor: Specifically developed for hydrogen fuel cell vehicles, it is corrosion-resistant and high-pressure resistant, facilitating the commercialization of hydrogen energy.

3. Gears and Transmission systems: Silent, efficient, modular
Silent Gear technology: It adopts an artificial tooth profile design to reduce the noise of the electric vehicle transmission and enhance the driving and riding comfort.

3D printed custom gears: Support small-batch flexible production to meet the demands of personalized vehicle models.

4. Green Filtration Technology: Innovation under the Zero-carbon Goal
To comply with the EU's 2035 ban on combustion, fully biodegradable filters have become a highlight. They can naturally decompose after being discarded, reducing microplastic pollution. In addition, the intelligent filtration system monitors the lifespan of the Filter element through sensors to optimize the maintenance cycle.

5. Lightweighting and intelligence of camshafts (Bumps)
Electromagnetic variable Camshaft: It enables stepless adjustment of valve timing and improves fuel economy.
Intelligent camshaft with built-in MEMS sensor: Real-time feedback of engine operation data, improving control accuracy.

Industry Trend Forum:
At the Global Auto Parts Summit held concurrently with the exhibition, experts pointed out:
Electrified crankshafts and hydrogen energy sensors will become the fastest-growing market segments in the next five years.
China's domestic supply chain has achieved global competitiveness in the fields of gears and filters, with export volume increasing by 30% year-on-year.
