[McKinsley]

IPA shows no information. There are up, down, left, and right buttons on the left side of the multifunction steering wheel. Press the left or right button to restore it. Introduction to Steering Wheel: The steering wheel is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft. Function of Steering Wheel: The steering wheel is generally connected to the steering shaft via splines. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft. Using a larger-diameter steering wheel reduces the hand force required from 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.
