The components of a steering box and their functions are as follows: 1. Pinion: Made of hardened steel, it is located in the steering box body. It meshes with the rack on one side and is connected to the steering shaft on the other. Its function is to convert the rotational motion of the steering shaft into linear motion of the rack. 2. Rack: A hardened steel bar with machined teeth that mesh with the pinion teeth. The rack's movement is controlled by the rotation of the pinion. It transfers the steering input from the pinion to the steering arms. 3. Steering Arms: Also known as axial arms, they are screwed into the rack at one end and can be connected to steering terminals or the steering knuckle at the other end. Their function is to transfer the movement of the rack to the steering knuckles, allowing them to rotate and steer the wheels. 4. Steering Terminals: Screwed onto the ends of the steering arms, they are spherical articulation pins that connect the steering box to the steering knuckle. They provide flexibility and allow for smooth movement of the steering system. 5. Adjustment Devices: Composed of springs, nuts, and a cover bolted to the steering box body, these devices are used to adjust the clearance between the pinion and the rack. They ensure proper engagement and minimize play in the steering system. 6. Protection Boots: Rubber protections mounted on the ends of the steering box body, fixed with metal clamps. They prevent dust and debris from contaminating the ends of the steering box, ensuring the smooth operation of the steering components. 7. Bushes: Made of lightweight alloy or nylon, they are mounted on the ends of the steering box. The rack runs inside them, reducing friction and facilitating the movement of the rack. 8. Bearing: Used on the pinion, it fits into a housing in the steering box body. The bearing provides proper support and reduces friction, allowing the pinion to rotate smoothly. These components work together to convert the rotational motion of the steering wheel into linear motion, enabling the driver to control the direction of the vehicle.
