A steering mechanism is a system that allows a vehicle, such as a car or bicycle, to change direction. It typically consists of components like the steering wheel, steering column, and linkages that connect to the wheels. When the driver turns the steering wheel, these components work together to pivot the wheels, enabling the vehicle to navigate curves and corners. There are different types of steering mechanisms, including rack and pinion and recirculating ball systems. Each type has its own advantages and is designed to provide precise control and responsiveness, ensuring safe and efficient handling of the vehicle.
