Abstract

Przedmiotem zgłoszenia jest mechanizm automatycznej przekładni łańcuchowej dla wózka inwalidzkiego z napędem ciągowym zawierający zespół zmiany przełożenia układu napędowego oraz układ sterowania zespołem zmiany przełożenia układu napędowego. W zespole zmiany przełożenia układu napędowego, ciąg wózka inwalidzkiego (1) współpracuje z wałem wewnętrznym piasty ciągu (4), który to skojarzony jest z jednym ze sprzęgieł. Sprzęgło (5) napędza momentomierz (6), który poprzez kolejne sprzęgło (5A) współpracuje z kołem łańcuchowym (8). Wał wewnętrzny piasty ciągu (4) osadzony jest w łożyskowanym mocowaniu wału napędowego (3), z drugiej zaś strony koło łańcuchowe (8) osadzone jest w łożyskowanym mocowaniu wału wewnętrznego (7), przy czym zarówno łożyskowane mocowanie wału napędowego (3) jak i łożyskowane mocowanie wału wewnętrznego (7) są przymocowane do ostoi. Nadto koło łańcuchowe (8) poprzez łańcuch napędowy I (9) współpracuje z przerzutką rowerową z wolnobiegiem (10), która to przerzutka rowerowa z wolnobiegiem (10) osadzona jest na wale pośrednim (12) wraz z kołem łańcuchowym wału pośredniego (17) tak, że wszystkie trzy elementy osadzone na wale pośrednim (17) obracają się razem, nadto koło łańcuchowe wału pośredniego (17) poprzez łańcuch napędowy (18) współpracuje z kołem łańcuchowym wału piasty koła (19), które to jest sztywno połączone z kołem napędowym (2) wózka inwalidzkiego.The subject of the application is an automatic chain transmission mechanism for a wheelchair with a traction drive, comprising a drive gear change assembly and a control system for the drive gear change assembly. In the drive gear change assembly, the wheelchair drive (1) cooperates with the inner shaft of the drive hub (4), which is associated with one of the clutches. The clutch (5) drives a torque meter (6), which, via another clutch (5A), cooperates with a chain wheel (8). The inner shaft of the drive hub (4) is mounted in a bearing mounting of the drive shaft (3), while on the other side the chain wheel (8) is mounted in a bearing mounting of the inner shaft (7), wherein both the bearing mounting of the drive shaft (3) and the bearing mounting of the inner shaft (7) are attached to the frame. Furthermore, the chain wheel (8) cooperates via a drive chain I (9) with a freewheel bicycle derailleur (10), which freewheel bicycle derailleur (10) is mounted on the intermediate shaft (12) together with the chain wheel of the intermediate shaft (17) so that all three elements mounted on the intermediate shaft (17) rotate together, and furthermore, the chain wheel of the intermediate shaft (17) cooperates via a drive chain (18) with the chain wheel of the wheel hub shaft (19), which is rigidly connected to the drive wheel (2) of the wheelchair.
