MAN-POWER OPERATED VEHICLE Russian patent published in 1997 - IPC

FIELD: mechanical and transport engineering; velomobiles and bicycles with chain drive between front wheel disks. SUBSTANCE: proposed invention makes it possible to increase riding speed, facilitated riding, decrease influence of side moment in handlebar , reduce aerodynamic resistance and increase service life of vehicle without increasing its overall dimensions. For this purpose bottom bracket is placed in center of bushing of driving front wheel which permits using of wheel with larger diameter of rim and, thanks to it, increase riding speed and facilitate running without increasing overall dimensions of vehicle. Use of disk wheels instead of spiked wheels considerably reduces aerodynamic resistance and increases service life of vehicle owing to the fact that all drive is protected from moisture and dust by disks. EFFECT: enlarged operating capabilities. 5 dwg
