9.1.2 Framed car body
In this case, there is a three- or two-compartment car body (in case you forgot what the "compartment" of the body is, see Chapter 2), which is installed and mounted on the frame, with engine compartment, passenger compartment, and luggage compartment. The frame has the form of a ladder, with two longitudinal side members, that are connected by crossbars. Chassis and transmission components, as well as the engine are attached to the frame. It turns out that all the loads when moving from the wheels through the suspension are transferred to the frame, the car body is affected by minimal loads. This design is good for SUVs, native element of which is off-road, where rigidity and reliability of the structure are important. The framed car body construction has also become widely used in pickup trucks, the main purpose of which is to transport weights.
But when it comes to comfort and handling, the frame blushes and is embarrassed because it has nothing to answer. Due to the fact that the body is attached to the frame at several points, and all the forces from the wheels are transmitted to this frame, the handling of the car disappears completely. Due to the frame, the car body shall not be lowered sufficiently relative to the chassis and the road. In this case the lowering limit of the center of gravity and the center of mass of the car is limited.
The integral car body is deprived of all shortcomings of a framed body.
