Technical Definition
The component frequently called a "Steering Spring Clock" is technically known in the automotive industry as a Clock Spring or Spiral Cable. It serves as the central nervous system of the steering column.
At Jiaxing Richang Auto Parts, we transform this "spring" into a high-precision electrical interface. Unlike basic wire harnesses, our spiral cables are engineered to maintain 100% electrical continuity between the vehicle's rigid chassis and the rotating steering wheel. With a monthly output of 2.8 million units and IATF 16949 certification, we supply the critical "springs" that power airbags for giants like Volvo, BYD, and SAIC GM Wuling.
Core Function: Beyond Basic Connectivity
The "spring" mechanism is actually a sophisticated Flexible Flat Cable (FFC). It must wind and unwind thousands of times without fatigue. Our manufacturing process ensures this component manages three vital lifelines:
Life-Saving Airbag Signal
The primary function is to trigger the Driver Airbag (DAB). We verify every unit using Japanese Kikusui insulation testers to guarantee the circuit triggers instantly during a collision.
Audible Warning (Horn)
High-current tracks designed to handle horn activation without overheating.
Digital Control Data
From Cruise Control to Voice Commands, our FFCs are produced on 11 automated punching lines to ensure precise data transmission for infotainment systems.
Why Choose Our Steering Springs?
1. Lab-Certified Safety (SGMW GP10)
Safety is verifiable. Our internal laboratory passed the stringent SGMW (SAIC GM Wuling) GP10 recognition in July 2016. We don't just guess; we test. Every batch undergoes Instantaneous Interruption Testing to ensure the "spring" never loses connection, even for a microsecond.
2. Millions of Cycles (Verified Durability)
A "steering spring" failure means an airbag failure. That is why we employ 4 dedicated SRC Rotary Durability Testers. We simulate the life of the vehicle-turning the wheel lock-to-lock millions of times-while subjecting the part to Three-Comprehensive Vibration and Thermal Shock (-40°C to +85°C) to prove it won't snap in winter or overheat in summer.
3. Wide OEM Compatibility
We manufacture "springs" for every vehicle type:
Passenger Cars: Compact U-Type designs for sedans like the Baojun 510/530 and Chery models.
Commercial Trucks: Heavy-duty Roller-Type units for Dongfeng, Sany Heavy Industry, and Renault, capable of ±4.8 turns for large steering boxes.
4. Advanced Feature Support
Modern steering wheels do more. Our springs support Steering Wheel Heating (via reinforced current tracks) and ADAS functions for Electric Vehicles (e.g., Neta/Hozon and Aion).
Industry Applications
Our steering springs are the invisible standard in:
New Energy Vehicles (EVs)
Handling high-data loads for digital cockpits in BYD and Geely models.
Logistics & Transport
Proven reliability in JMC Ford Transit vans and Foton light trucks.
Heavy Construction
Ruggedized connectors for Sany excavators and cranes.
FAQ: Troubleshooting & Specs
Q1: What actually breaks inside a "Steering Spring"?
A1: The internal ribbon cable (FFC) can fatigue and snap if not manufactured correctly. We prevent this by controlling the entire lamination and punching process in-house, ensuring the copper conductors have the perfect flexibility and thickness.
Q2: Will a broken spring affect my brakes or engine?
A2: No. A broken steering spring primarily disables the Airbag, Horn, and Steering Wheel Buttons. However, because it disables the airbag, it is a critical safety failure that renders the vehicle unsafe to drive.
Q3: Do you make springs for trucks?
A3: Yes. We have a dedicated line of Roller-Type clock springs specifically for commercial vehicles (like Volvo and Shaanxi Auto) that require more turns (rotations) than a standard car.
Q4: How do I know if the spring is OEM quality?
A4: Look for validation. OEM-quality parts are tested in certified labs (like our GP10 facility) for Salt Spray Corrosion and Dust Resistance. Cheap aftermarket parts often skip these tests, leading to early failure.
