Why Does Electric Power Steering Become Heavier?
1 Answers
The reasons for electric power steering becoming heavier include: 1. Excessive tightness between the rolling bearings and sliding bearings connected to the steering system: This can reduce the lubrication effect of the bearings, causing sticking, which then reflects in the steering wheel's performance. 2. The pump pressure of the power steering pump fails to meet the standard value: This results in a heavy feeling when using the steering wheel. Check the flow control valve; during driving, leaks in the flow control valve or safety valve can be repaired by grinding, and then check if the spring of the safety valve has failed. 3. Low hydraulic pressure in the power steering system: If the steering wheel becomes heavy due to low hydraulic pressure in the steering system, it is necessary to promptly visit a repair shop for maintenance. 4. Long-term lack of maintenance or untimely replacement of the return oil filter in the oil reservoir: This can lead to poor circulation of the power steering fluid, making the steering wheel feel heavy.
