6.1.6 Guiding / connecting elements
The wheel is attached to the car body or sub frame using guides and connecting elements. These connecting elements are divided into levers and rods. The bar is a hollow profile, usually of a circular cross-section, less often of a square. In fact, it is just a tube with lugs that are welded to both ends for installing rubber bushings in them, with which it is attached to the car body and the steering knuckle or axle journal. Levers are structurally more complex elements. They can be welded from tubes (this design is used mainly in sports cars), cast, for example, from an aluminum alloy (to make them lighter) or stamped from sheet metal (to be cheaper). The number and location of levers affect the ride and handling of the car.
