Why is the electric power steering wheel slow and weak to return to center?
1 Answers
Electric power steering wheel returning slowly and weakly is caused by changes in wheel alignment parameters and damage to the steering gear. A car's wheel is an assembly consisting of a tire and a rim. However, due to manufacturing reasons, the mass distribution of various parts of this assembly cannot be perfectly uniform. When the wheel rotates at high speed, it forms a dynamic imbalance, causing phenomena such as wheel wobbling and steering wheel vibration during driving. Solutions for steering wheel not returning to center: 1. Adjust wheel alignment: Generally, when a vehicle exhibits the phenomenon of the steering wheel not returning to center, the first solution that comes to mind is adjusting the wheel alignment. Wheel alignment refers to the relative positional relationship between the wheels and the chassis (wheels, steering knuckles, front axle, etc.). If the wheel alignment parameters change, it can lead to issues such as the steering wheel not returning to center, heavy steering, steering pull, and tire wear. 2. Replace the steering gear: If the steering wheel still does not return to center after adjusting the wheel alignment, then the cause can be ruled out as wheel alignment. After eliminating wheel alignment, the most likely cause is the steering gear. When the steering gear malfunctions and its reverse efficiency decreases, the steering wheel will have difficulty returning to center.
