What type of system includes parts like the rod and spindle?

The steering system in a vehicle is designed to allow the driver to guide the vehicle's direction smoothly and safely. Within this system, components such as the rod and spindle play critical roles. The rod, often referred to as the tie rod, connects the steering gear to the wheels, allowing for controlled movement. The spindle, which is part of the wheel assembly, connects to the tie rod and is crucial for steering, as it helps pivot the wheel when the driver turns the steering wheel.

This design ensures that the driver can maneuver the vehicle effectively, translating the turning of the steering wheel into the corresponding motion of the wheels. The rod and spindle are directly linked to the steering process, making them essential components of the steering system.
