Steer arm refers to a component of a steering system in vehicles, particularly in automobiles and heavy-duty vehicles, which facilitates the operation of steering and control of the vehicle's movement. Specifically, a steer arm is a mechanical linkage or lever that connects the steering box or rack to the steering knuckle or axle. This arm is typically connected to the pitman arm, which receives input from the driver through the steering wheel.
The primary function of the steer arm is to convert the rotational motion of the steering wheel into lateral movement, allowing the driver to control the direction of the vehicle. As the driver turns the wheel, the steer arm transmits this motion to the steering knuckle, which ultimately changes the angle of the wheels. This, in turn, determines the direction the vehicle will travel.
Steer arms are commonly made of durable materials like steel, forged or cast, ensuring strength and reliability. They are typically designed to withstand the considerable forces and stresses exerted on them during steering maneuvers.
It is important to note that the steer arm is an integral part of the vehicle's suspension and steering systems, working in conjunction with other components such as tie rods, ball joints, and control arms. It plays a crucial role in maintaining stability, control, and responsiveness while driving, contributing to overall safety and maneuverability.
