What is the difference between turning one and a half turns and turning to the lock?
2 Answers
The steering wheel's one full turn has a larger turning amplitude than half a turn. Here is some extended information about the steering wheel: 1. Introduction: A wheel-shaped device used to control the direction of cars, ships, airplanes, etc. This new design of the steering wheel emerged as the times required, introducing a gear system between the driver and the wheels that operates flexibly and effectively isolates severe vibrations from the road. 2. Function: The steering wheel is generally connected to the steering shaft via splines, and its function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. Using a steering wheel with a larger diameter reduces the hand force required from the driver when turning. The steering intermediate shaft, as a connecting piece between the steering gear and the steering shaft, facilitates the standardization of the steering gear, compensates for errors during manufacturing and installation, and makes the installation of the steering gear and steering wheel on the vehicle more reasonable.
I've been driving for over 20 years. Turning the steering wheel one and a half turns (approximately 540 degrees) is commonly used for general turns, such as left or right turns on city roads. It's a simple operation that doesn't require reaching the limit. 'Turning to the lock' means rotating the steering wheel to its maximum position, one and a half turns to either side, achieving the vehicle's maximum steering angle. This is the ultimate operation used for parking in tight spaces or making U-turns. The main differences lie in purpose and risk: one and a half turns offers more precise control, while turning to the lock maximizes capability in extreme situations but may damage the power steering pump with prolonged use and increase wear. For daily driving, I'd recommend turning to the lock only when necessary, such as for quick adjustments while reverse parking. Otherwise, using one and a half turns for normal turns saves effort and maintains the vehicle.
