FIELD: transport engineering; freight tricycles. ^ SUBSTANCE: invention relates to folding freight cycles designed for riding at reclining and with drive to front wheel. Transmission of proposed cycle consists of two strands of chain and/or belt drives interconnected by propeller shaft 16 or flexible shaft. Center 17 of cross of propeller shaft 16 is located on turning axle of front wheel fork 3 which is made in form of turned-over Y letter. Carrying frame consists of beam 1 and container interconnected by detachable joint. Cover of container is made in form of folding chair. Chain of first strand of drive is placed inside box beam 1. Second strand of drive is installed on fork 3 and it engages drive sprocket 12 in aperture 24 of vertical section of fork 3. ^ EFFECT: reduced overall dimensions of transmission and load on fork. ^ 9 cl, 11 dwg |
