1.Why do the multifunctional steering wheel rely more on clock springs?
Traditional steering wheels usually only require to be connected to a horn and airbag system.
The modern Kia multifunctional steering wheel integrates a lot of electronic controls, therefore more lines are required for signal transmission.
As the steering wheel continues to rotate, the Clock springs need to maintain these electronic systems steadily connected.
2.The multifunctional steering wheel integrates more electronic features.
Modern Kia multifunctional steering wheels general integration:
Sound Control Button
Bluetooth phone buttons
Multimedia Control
Cruise control
Voice control system
Drive computer control
paddle changer
These functions require signal transmission through the internal circuit of the clock spring.
The more functions, the higher the requirement for the number and stability of clock spring circuits.
3. Clock springs need to transmit more signals
Normal steering wheel wiring is relatively simple.
But the multifunctional steering wheel needs to be transmitted simultaneously:
Power signals
button signal
CAN Communications Signal
Airbag circuit
Audio Control Signal
As a result, more wires and more complex circuit structures are often used inside the clock springs.
If the stability of the circuit is not enough, it is easy to cause abnormal function.
4. Frequent steering wheel rotation increase wiring load
During daily driving, the steering wheel of a vehicle needs to turn constantly from side to side.
The internal wiring of the clock spring is also wound and stretched repeatedly.
Multi-purpose steering wheel with more body lines:
Connection structure is complicated.
Higher bending frequency
Long-term wear and tear is more pronounced.
This places forward a higher requirement for the durability of clock spring material.
5. Multi functional steering wheel are more prone to electronic couplings.
If a normal clock spring is damaged, it usually only affects the horn or airbag.
But the multifunction steering wheel, if the clock spring fails, it can also lead to:
Steering wheel button malfunction
No Bluetooth
Cruise control glitch
Trumpet broken
malfunction light is on
Therefore, the multifunctional steering wheel requires high stability of clock spring.
