A steering mechanism is a system that allows a vehicle to change direction. It typically consists of components like the steering wheel, steering column, and steering gear. When the driver turns the steering wheel, the movement is transmitted through these components to the wheels, enabling the vehicle to turn left or right. There are various types of steering mechanisms, including rack and pinion and recirculating ball systems. Each type has its own advantages and is used in different vehicles. Proper functioning of the steering mechanism is crucial for safe driving and maneuverability.
