What are the reasons for the steering wheel not turning?

[OJuniper]

The reasons for the steering wheel not turning are: 1. Damage to the power steering pump; 2. Automatic steering wheel lock; 3. Air not being completely purged from the system after fluid leakage. The automatic steering wheel lock is a simple anti-theft feature. Sometimes when parking, the steering wheel is positioned at a certain angle where turning the ignition key alone cannot unlock it, leading to this situation. The steering wheel is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. Generally, the steering wheel is connected to the steering shaft via splines, and its function is to convert the force applied by the driver on 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 by the driver when turning. The steering intermediate shaft, as a connecting component 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 more reasonable in the vehicle.
