What Causes the Electric Power Steering Wheel to Become Heavy?
1 Answers
There are four main reasons why an electric power steering wheel becomes heavy: 1. The fit between the rolling bearings and sliding bearings connected to the steering system is too tight, leading to reduced lubrication effectiveness and causing a sticking phenomenon. 2. When the pump pressure of the power steering pump fails to meet the standard value, the steering wheel will feel heavy during use. Check the flow control valve. During driving, leaks in the flow control valve or safety valve can be repaired by grinding. Also, check if the spring of the safety valve has failed. 3. When the hydraulic pressure of the steering gear is low, the steering wheel will feel heavy. If the steering wheel becomes heavy due to low hydraulic pressure in the steering gear, promptly take the vehicle to a repair shop for maintenance. 4. Long-term lack of maintenance of the return oil filter in the oil reservoir can cause blockage, resulting in poor circulation of the power steering fluid and making the steering wheel heavy.
