Abstract

Tenk M-84 sadrži robusni sustav ovjesa koji značajno doprinosi njegovoj izdržljivosti i učinkovitosti u borbi. Ovjes tenka M-84 je tipa s torzijskim oprugama, poznat po svojoj jednostavnosti i pouzdanosti. Svaka strana tenka opremljena je sa šest potpornih kotača, pri čemu su prvi i zadnji kotač opremljeni hidrauličkim amortizerima koji ublažavaju udarce na neravnom terenu. Ova postavka pomaže u održavanju stabilnosti tenka i udobnosti posade pri prelasku preko neravnih površina pri velikim brzinama. Torzijske opruge, izrađene od čelika, uvijaju se pod opterećenjem kako bi apsorbirale udarce, smanjujući trošenje konstrukcije tenka i omogućujući mu da zadrži stabilnost pri gađanju. Sustav gusjenica također je osmišljen s ciljem da izdrži u teškim terenskim uvjetima. Ukratko, sustav ovjesa tenka M-84 osmišljen je s ciljem pružanja ravnoteže između mobilnosti i zaštite, omogućujući učinkovito djelovanje u raznim terenskim uvjetima. U ovom radu prikazan je osnovni proračun ovjesa tenka M-84 pomoću skica i dijagrama te je ukratko predstavljena analiza utjecaja karakteristike vozila na karakteristiku ovjesa.

Abstract (english)

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.
