What need does the drag link fulfill in the steering system?

• A. Provide power to the alternator
• B. Connect the pitman arm to the tie rod
• C. Support the weight of the bus
• D. Stabilize the water pump

Answer: (B)

The drag link is a critical component in the steering system of a bus, as it serves to connect the pitman arm to the tie rod. This connection is essential for the functioning of the steering mechanism. When the driver turns the steering wheel, the pitman arm moves, causing the drag link to transfer that motion to the tie rod. As a result, the wheels turn in response to the driver's input, allowing for maneuverability and control of the bus. This relationship between components ensures that steering is efficient and responsive, which is vital for safety and operation, especially in a school bus where transporting children is a responsibility that demands precision in handling.
