The abnormal noise of the car clock spring may be related to many factors. The following is a detailed summary of these factors:
1. Internal problems of the clock spring
Due to its unique structural characteristics:
The clock spring is composed of multiple parts such as a wiring harness, a housing that moves relative to each other, a neutral pin, and a flexible flat cable.
When the steering wheel rotates, the housing of the clock spring may collide, which may cause abnormal noise.
Problem about the fixing point:
If the fixing point of the clock spring (such as the fixing point on the stator) is not in the same plane or the tightening torque is not set properly, the clock spring may be eccentric.
Due to the eccentricity, the stator and rotor of the clock spring may collide, resulting in abnormal noise.
2. Problems about how the steering wheel and clock spring work together
Problems about installation:
If the steering wheel and clock spring are not placed or installed properly, they may rub or collide when rotating.
The size of the slot is not consistent:
The size of the slot on the steering wheel frame does not match the driving shaft and driven shaft of the clock spring, which may also cause abnormal noise.
3. Other related factors
Some parts are loose:
The vibration generated when the vehicle is driving may make the clock spring or its related components (such as fixing screws) unstable, resulting in abnormal noise.
Plastic parts expand due to heat and contract due to cold:
When the temperature fluctuates greatly, the plastic part surrounding the clock spring may deform due to temperature changes, and this deformation may cause abnormal noise due to the extrusion and friction between them.
4. Troubleshoot and confirm the abnormal noise
In order to accurately determine the origin of the abnormal noise, we can perform the following inspection and verification procedures:
Disassemble the clock spring: Rotate the clock spring independently to observe whether abnormal noise is generated. If the abnormal noise no longer occurs, it may be caused by the matching problem between the steering wheel and the clock spring or other related factors.
Check the looseness of the parts: Make sure that there is no looseness in the clock spring and its related parts, and tighten them immediately if looseness is found.
Regarding the adjustment of the installation position: If the abnormal noise is caused by installation problems or inconsistent slot sizes, you can consider changing the placement or method of the clock spring and the steering wheel.
When the clock spring or its related components are severely damaged, it is necessary to replace it.
