B. Center link.
C. Upper control arms.
D. Lower control arms.
The correct answer and explanation is :
The correct answer is A. Steering arms.
Explanation:
In a parallelogram steering linkage, the tie rods are parallel to the steering arms. This design is a fundamental feature of steering systems used in many vehicles, especially older models or certain types of trucks.
To better understand why the answer is “steering arms,” let’s break down the key components of a parallelogram steering linkage:
- Steering Arms: These are the parts of the steering system that are attached to the wheels. They convert the rotational motion of the steering wheel into the linear motion required to turn the wheels. Steering arms are mounted to the knuckle or spindle of each wheel.
- Tie Rods: Tie rods are the components that connect the steering mechanism (such as the steering gear or rack) to the steering arms. They play a crucial role in transmitting the motion from the steering gear to the wheels. In a parallelogram linkage system, the tie rods maintain the alignment of the steering mechanism by ensuring that both wheels move in unison when turning.
- Parallelogram Linkage: The linkage includes several components, such as the center link, idler arm, pitman arm, and tie rods. The tie rods are typically located in a way that they stay parallel to the steering arms. This configuration ensures that when one wheel is turned, the other wheel is turned to the same degree, maintaining proper alignment and preventing issues like steering instability or unequal turning angles.
In the parallelogram system, this parallel alignment between the tie rods and steering arms is crucial because it ensures that the steering movement is consistent and balanced across both wheels, giving the driver smooth and predictable steering response.
The other options (B, C, and D) are not correct because the tie rods are specifically designed to interact directly with the steering arms, not with the center link, upper control arms, or lower control arms.
