ABSTRACT The article analyzes the viability of military vehicles from the effects of conventional damage (bullets, splinters), etc. When fired, a car that stops for a short time becomes an easy target and is destroyed. The presence of a tire pressure control system on the vehicles substantially increases the possibility of continued traffic. However, the opportunities of the mobility adjustment system is limited. The required survivability can only be ensured if special wheels are used. RunFlat (flat tire) is the common name for tireless tire technology. The RunFlat car wheel inserts allow you to continue driving after a tire has been punctured or descended, which can, for example, allow the machine to exit the firing zone. The essence of technology is to strengthen the sidewalls of tires. Hutchinson produces wheel inserts of two types - RODGARD and CRF. The RODGARD RunFlat (Rotary RunFlat) system is capable of providing deflated tires thanks to a special patented design. The CRF RunFlat (Static RunFlat) system is a wheel insert that is used as a single unit of the center of the wheel and tubeless tire. Сommon CSR (Conti Support Ring) system includes a metal ring that is fastened to the rim. The disadvantage of this system is that the support ring will only fit in the high profile wheels. The first cars wish RunFlat in the Armed Forces of Ukraine were KrAZ Cougar and Spartan cars. In turn, the main disadvantages of using wheels with RunFlat include, in addition to the much higher cost, the inability to use the tire after long distances. Airless tire (non-pneumatic) is an innovative development that is a one-piece wheel that can replace both the wheel disk and the pneumatic tire.The main advantage of this design is that the wheel does not require pumping, is not afraid of punctures, is resistant to damage and has a long service life. In this case, the weight of the wheel is almost twice as light, the life of such a wheel is two to three times longer, but the cost is more than twice the price of standard wheels. It is proved that the grip of the road surface in such tires is not inferior to traditional tires, and rolling resistance has decreased to hundreds. The Polaris Defense non-pneumatic wheels guarantee significantly better durability than standard tires and can withstand a 12.7mm bullet. The disadvantage of using non-pneumatic (airless) wheels is to create additional load on the suspension of the car due to their rigidity. |
