The object of the invention is a kinematic diagram of a velomobile with hand drive and control. Such kinematics can operate on the velomobile with hand drive and control, which can be used as an everyday transport vehicle, as well as sports equipment, including for people with limited functionality of feet. The essence of the invention is to provide kinematic diagrams of two-, three- and four-wheel velomobiles powered and controlled manually using a handle bar 1. This is achieved by introducing into a kinematic diagram of velomobile of a tilting steering column (TSC), which, firstly, by its hard frame (upper semiaxle 3 and lower semiaxle 6, lower casing 7, lever 14) operates (with assistance of a rocker beam 18) as a lever and transforms effort on the handle bar 1 into traction of a chain 15 on a driven sprocket of rear wheel 16; secondly, design of the upper part of TSC, namely presence of the upper casing 2 coaxially positioned relative to the upper semiaxle 3 (part of hard frame of TSC) connected thereto by upper 4 and lower 5 bearing units with possibility of free rotation around the axle 3 allows turning the handle bar 1, upper casing 2 and lever 14 through a linkage 24, 29, 35, spherical pairs 23, 26, 30, 31, 36, 37 and a winker 25 and transformation into synchronous rotations of forks 33. 38 forks of left and right wheels; thirdly, the lower semiaxles 6 of TSC and lower casing 7 of TSC are coaxially positioned and interconnected by the upper 8 and lower 9 slide bearing units that allows to change the length of lower part of TSC (fixing position of the lower casing 7 of TSC relative to the lower semiaxle 6 of TSC through a stopper 10). Variability of the length of lower part of TSC allows to perform the function of a gearbox of velomobile. The disclosed kinematic diagram allows to create structurally simple, reliable and easy to use velomobiles with hand drive and control that can be also used by people with limited functionality of feet. |
