Challenges and Solutions in Smart Chassis Assembly: With the rapid development of automotive electrification and intelligent driving technologies, the by-wire chassis—as a core executive system—has placed unprecedented demands on assembly precision, safety and reliability, and full lifecycle data traceability.The Dongfeng Yuxin Intelligent Chassis Project is a key strategic initiative aligned with this trend.
In this project, Desoutter Power Tools is deeply involved in the construction of the production line for its by-wire braking products, providing a high-precision intelligent tighteningand tightening big data-driven technologies, jointly building a new ecosystem for intelligent chassis assembly technology.
I. Project Background: Dongfeng Yuxin Intelligent Chassis
The Dongfeng Yuxin Intelligent Chassis project is advancing rapidly, and its first line-controlled braking (IBC) product production line has essentially achieved the capability for automated assembly and functional testing.Once the project goes into production, it will focus on the R&D, manufacturing, and industrialization of intelligent chassis technology, establishing a leading domestic production base for by-wire chassis products.
The primary functions of the IBC Final Assembly Line L1 are: fully automated assembly and testing of brake-by-wire controllers and assemblies. The production line integrates advanced automation technologies such as robotic loading/unloading, vision-based positioning, closed-loop torque control, and 100% test traceability.
II. Core Solution: Smart Torque Tightening Stations as Standard Across the Entire Production Line
Desoutter Tools provided a smart tightening solution for the critical assembly stages of Dongfeng Yuxin’s IBC production line, with the following key features:
-
Fully Automatic Servo Tightening: All critical connection points utilize a fully automatic servo torque tightening system, ensuring precise torque control and fully meeting the high reliability and safety assembly standards required for smart chassis.
-
Closed-Loop Data System: Each tightening station integrates a data acquisition and feedback system, achieving a complete closed-loop process from tightening execution and result verification to data upload.
-
Standardization and Digitalization: Standardized management of tightening processes and data has laid a solid foundation for Dongfeng Yuxin to achieve standardization, digitalization, and intelligent iteration of smart chassis assembly processes.
III. Core Value: Tightening Data Drives Production Line Capability Upgrades
The deeper value of this project lies in the establishment of a production system driven by tightening data, specifically manifested in:
-
Real-time Data Collection Throughout the Entire Process: Data from the entire tightening process for every bolt (including torque, angle, speed, yield point, etc.) is recorded and retained in real time.
-
Establishment of a tightening process database: Through intelligent curve analysis, process parameters are continuously iterated and optimized using historical data.
-
Intelligent Quality Control: Enables automatic anomaly alerts and deviation tracing, transforming quality control from “post-event inspection” to proactive management involving “pre-event prevention, in-process monitoring, and post-event traceability.”
-
Full Lifecycle Traceability:All tightening data is recorded on the blockchain and integrated with the factory MES system, ensuring that the tightening data for every smart chassis product throughout its entire lifecycle is searchable, traceable, and reviewable.
IV. Summary of Solution Value
Through the implementation of this project, Dongfeng Yuxin’s intelligent chassis production line has achieved:
-
High Safety and High Consistency: Precise torque control ensures the assembly reliability of safety components such as by-wire braking systems.
-
Quality Improvement and Cost Reduction: Data-driven process and cycle time optimization effectively reduced defect rates, achieving smart manufacturing goals.
-
Full Lifecycle Traceability: A comprehensive tightening quality record is established to meet the automotive industry’s stringent traceability requirements.
