What does a Double Wishbone suspension system utilize for its structure?

A Double Wishbone suspension system is characterized by the use of both an upper control arm and a lower control arm. This configuration allows for a greater range of motion and better handling characteristics than systems with fewer components. The dual control arms manage the wheel's vertical position and alignment by maintaining a consistent relationship with the vehicle body. This setup provides superior control over camber and toe angles during suspension travel, which enhances grip and stability during cornering and uneven road conditions.

In contrast, a single control arm would not provide the same level of stability or adjustment capabilities. The torsion bar system, while a suspension method, does not specifically refer to the control arm structure typical of double wishbone setups. A simple beam axle represents a different kind of suspension design, often seen in older or heavier vehicles, where axle housing supports the wheels rather than using articulated arms. Thus, the option of upper and lower control arms aligns perfectly with the structural requirements of a Double Wishbone suspension.
