Sherman Tank Suspension

The Sherman tank, officially known as the Medium Tank, M4, was the most widely used medium tank by the United States and Western Allies in World War II. A key feature contributing to the Sherman's longevity and versatility on the battlefield was its suspension system. The Sherman utilized a unique suspension setup known as the Vertical Volute Spring Suspension (VVSS).

The VVSS system featured two road wheels mounted on a bogie assembly, with each wheel pair supported by a large, vertically mounted coil spring. This design allowed for a smoother ride over rough terrain, enhancing the tank's mobility and the crew's ability to maintain control at higher speeds. Later models of the Sherman introduced the Horizontal Volute Spring Suspension (HVSS), which offered even greater stability and improved weight distribution.

The evolution of the Sherman tank's suspension system highlights the importance of adaptability in armored vehicle design, ensuring that the Sherman remained a formidable force throughout the conflict and beyond.
