Steering gear is a crucial component in vehicles that helps control the direction of movement. It translates the driver's input from the steering wheel into the movement of the wheels. This system can be mechanical, hydraulic, or electric, depending on the vehicle's design and technology. The most common types of steering gear include rack and pinion and recirculating ball systems. In a rack and pinion setup, a round gear (the pinion) engages with a flat bar (the rack), allowing for precise steering. Meanwhile, the recirculating ball system uses a series of balls to reduce friction, providing a smoother steering experience.
