Abstract

Przedmiotem zgłoszenia jest zespół piasty koła napędowego wózka inwalidzkiego do napędów wielobiegowych. Zespół połączony jest do ramy wózka inwalidzkiego za pomocą dwuczęściowego łącznika składającego się z łącznika górnego (1) i łącznika dolnego (2), przy czym łącznik górny (1) posiada szynę (3) łączącą go z ramą wózka inwalidzkiego, łącznik dolny (2) wyposażono w obejmę dociskową (4) przykręcaną do niego za pomocą czterech śrub łącznika (5), nadto łącznik górny (1) i dolny (2) są połączone poprzez skręcenie śrubą i nakrętką, łącznik górny (1) posiada otwór cylindryczny (8), w którym osadzono nieprzesuwnie dwa łożyska toczne kulkowe (9), które to łożyska toczne kulkowe (9) w dolnej części podparte są na korpusie piasty (10) i dwóch osadzonych na korpusie piasty (10) pierścieniach osadczych (11), korpus piasty (10) wyposażono w dwa kołnierze (12) z otworami (13) do osadzenia szprych oraz cylindryczne podtoczenie piasty (14) do osadzenia koła przekładni ciągowej, wewnątrz korpusu piasty (10) osadzono nieruchomo dwa łożyska igiełkowe (15) podpierające wał ciągów (16), przy czym wał ciągów (16) na jednym z końców posiada cylindryczne podtoczenia wału (17) do osadzenia ciągów, na drugim końcu posiada drążenie (18), w którym osadzany jest czop (19), zabezpieczany w wale ciągów (16) za pomocą śruby osadczej (20).The subject of the application is a wheelchair drive wheel hub assembly for multi-speed drives. The assembly is connected to the wheelchair frame using a two-part connector consisting of an upper connector (1) and a lower connector (2), where the upper connector (1) has a rail (3) connecting it to the wheelchair frame, the lower connector (2) equipped with a pressure clamp (4) screwed to it using four connector screws (5), moreover, the upper connector (1) and lower (2) are connected by screwing with a screw and nut, the upper connector (1) has a cylindrical hole (8), in which two ball bearings (9) are mounted non-slidingly, the ball bearings (9) in the lower part are supported on the hub body (10) and two circlips (11) mounted on the hub body (10), the hub body (10) ) is equipped with two flanges (12) with holes (13) for mounting the spokes and a cylindrical hub undercut (14) for mounting the thrust gear wheel, inside the hub body (10) there are two needle bearings (15) fixedly mounted, supporting the thrust shaft (16), wherein the string shaft (16) at one end has cylindrical shaft reliefs (17) for mounting the strings, and at the other end it has a hollow (18) in which the pin (19) is mounted, secured in the string shaft (16) with a screw settlement (20).
