Abstract

Niniejsze zgłoszenie dotyczy dziedziny techniki wózków i przedstawia wózek trójosiowy z zawieszeniem na stalowych resorach piórowych (3) oraz pojazd szynowy. Na każdej stronie zespołu zestawu kołowego (2) umieszczony jest wyłącznie układ zawieszenia na stalowych resorach piórowych (3), przy czym oba końce tego układu połączone są z gniazdami mocowania resorów stalowych na zespole ramy, natomiast środkowa dolna część układu zawieszenia połączona jest z górną częścią każdego zespołu skrzynek osiowych. Zespół ramy ma konstrukcję utworzoną przez dwie belki boczne i dwie belki czołowe, dzięki czemu wózek trójosiowy charakteryzuje się prostą budową oraz uproszczonym montażem przy jednoczesnym zachowaniu wymaganej nośności. Ponadto trójosiowy wózek jest wyposażony w hamulec klockowy dwustronnego działania, dzięki czemu zestaw kołowy przenosi jednakowe siły po obu stronach podczas hamowania, klocki hamulcowe charakteryzują się szybkim odprowadzaniem ciepła i niewielkim zużyciem, a liczba klocków działających na każde koło jest podwojona, co skutkuje dwukrotnym zwiększeniem powierzchni przenoszenia siły hamowania. W przypadku przewozu ciężkich ładunków jednostkowe ciśnienie działające na powierzchnię klocków hamulcowych ulega zmniejszeniu przy zachowaniu niezmienionej całkowitej siły docisku klocków, co wydłuża trwałość kół oraz samych klocków hamulcowych.This application relates to the field of bogie technology and describes a three-axle bogie with steel leaf spring suspension (3) and a rail vehicle. Each side of the wheelset assembly (2) is equipped solely with a steel leaf spring suspension system (3), with both ends of the suspension system connected to the steel spring mounting sockets on the frame assembly, while the lower central portion of the suspension system is connected to the upper portion of each axle box assembly. The frame assembly is constructed with two side beams and two end beams, providing the three-axle bogie with a simple structure and simplified assembly while maintaining the required load capacity. Furthermore, the three-axle bogie is equipped with a double-acting shoe brake, allowing the wheelset to transmit equal forces on both sides during braking, the brake pads to dissipate heat quickly and reduce wear, and the number of pads acting on each wheel is doubled, resulting in a doubling of the braking force transfer area. When transporting heavy loads, the specific pressure acting on the brake pad surface is reduced while maintaining the total pad pressure force unchanged, which extends the durability of the wheels and the brake pads themselves.
