The M-84 tank features a robust suspension system that significantly contributes to its durability and combat effectiveness. The suspension system of the M-84 is a torsion bar type, which is known for its simplicity and reliability. Each side of the tank is equipped with six road wheels, with the first and last road wheels fitted with hydraulic shock absorbers to cushion the impacts from rough terrain. This setup helps maintain the tank’s stability and crew comfort while traversing uneven ground at high speeds. The torsion bars, made from spring steel, twist under load to absorb shocks, reducing the wear on the tank’s structure and allowing it to maintain a steady firing platform. The track system is also designed to withstand heavy use and improve traction. Overall, the M-84's suspension system is designed to provide a balance between mobility and protection, allowing it to operate effectively in various environments. In this paper, a basic calculation of the suspension system of the M-84 tank is presented using various sketches and diagrams, and a brief analysis of the influence of the vehicle's characteristics on the suspension characteristics is provided.
