The suspension system is the collective term for all force-transmitting linkages between a vehicle’s frame and its axles or wheels. Its primary functions are to transmit forces and torques between the wheels and the frame, to cushion impacts transmitted from uneven road surfaces to the frame or body, and to dampen vibrations, thereby ensuring smooth and comfortable vehicle operation. A typical suspension system comprises elastic elements, guiding mechanisms, and shock absorbers; some designs also include bump stops and anti-roll bars. Elastic elements come in various forms, such as leaf springs, air springs, coil springs, and torsion-bar springs. Modern passenger cars generally use coil springs and torsion-bar springs, while certain high-end models employ air springs. The suspension system is a critical vehicle assembly that elastically connects the frame to the wheels, significantly influencing multiple aspects of vehicle performance. From an external perspective, a car’s suspension may appear to consist merely of rods, cylinders, and springs; however, it should not be underestimated. On the contrary, automotive suspension is a complex assembly that is difficult to perfect, as it must simultaneously meet both comfort and handling‑stability requirements—two objectives that often conflict with one another.

As one of the vehicle’s key components, the cab is the workspace for the driver and passengers, with its performance primarily evaluated in terms of safety, ride smoothness, and comfort. The Cab mounting system refers to the entire assembly that secures the cab to the vehicle frame, providing support and damping vibrations. It is a critical component that connects the cab to the frame, with its main constituents being elastic elements and vibration-damping components.

The suspension system serves as the interface between the powertrain and the vehicle body, primarily supporting the powertrain, mitigating its vibrations from affecting the entire vehicle, and limiting vibration levels. It plays a crucial role in the vehicle’s overall NVH performance. Nowadays, entry-level vehicles typically employ three- or four-point rubber mounts, while higher-end models often combine these with hydraulic mounts.
