How large is a 5-degree steering wheel angle?
2 Answers
Using the center of the steering wheel as the pivot point and the steering wheel's radiation angle as the reference, you can determine the degree of deviation in the car's steering wheel. Generally, a deviation exceeding 1.5 degrees can cause a delay in the car's steering response. A 5-degree turn is approximately one-tenth of a full steering wheel rotation. Additional information: There are three common steering wheel malfunctions: 1. Steering wheel lock: This occurs when the steering wheel cannot be turned, typically due to the anti-theft system activating after the car is turned off. The steering wheel automatically unlocks when the car is started. 2. Steering wheel scratches: This issue can be resolved by taking the car to a professional auto repair shop for maintenance and repair. 3. Steering wheel vibration: This usually happens at speeds between 80 to 90 kilometers per hour and typically resolves once the speed exceeds 90 kilometers per hour.
Last time when adjusting the steering gear at the shop, we happened to measure this data. A 5-degree steering wheel angle is actually very small. For a standard family car, the total steering wheel rotation is about 2.5 turns (900 degrees), so 5 degrees accounts for less than 2%. To put it visually, if you place your phone flat on the steering wheel and lift one edge of the phone to the height of a coin (approximately 3-5mm), that tilt angle is roughly 5 degrees. When driving, the slight movement of your fingers on the steering wheel is typically around this angle, at which point the wheel's turning angle might be less than 0.5 degrees, and the car hardly deviates. However, it's important to note that if the steering wheel has a dead zone exceeding 5 degrees, you'll noticeably feel the car wandering during turns.
