What Causes Steering Wheel Vibration in New Energy Electric Vehicles?
1 Answers
New energy electric vehicle steering wheel vibration is primarily caused by inaccurate four-wheel alignment data and wheel balance issues. Below are detailed explanations: Inaccurate four-wheel alignment data: All four wheels of a vehicle have specific alignment parameters, and they are not simply perpendicular to the ground. It is recommended to perform regular four-wheel alignment checks for your vehicle. If steering wheel vibration occurs when driving between 80 to 90 km/h but disappears when exceeding 90 km/h, this is typically caused by misaligned wheel positioning data. Wheel balance problems: After tires are mounted on rims, some sections of the wheel assembly may be heavier than others, causing vibration during high-speed rotation. It is necessary to check whether the front wheel alignment angles and toe-in meet specifications, and make adjustments if deviations are found. Lift the front axle to rotate the wheels and inspect their static balance condition, as well as check for excessive tire deformation. Deformed tires should be replaced.
