[0002] A steering wheel is a wheel-shaped device used to control the direction of a vehicle such as a car, ship, or airplane. The main function of a steering wheel is to convert the force exerted by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering shaft to achieve directional control of the vehicle. A steering wheel is usually installed in the cab of a vehicle. Its design includes a frame, foam, and mounting buckles or screw holes corresponding to the main driver's airbag DAB.
