FIELD: transport engineering; entertainments. ^ SUBSTANCE: proposed vehicle contains traction motor 47 and stepless gearbox - variable-speed drive. Used as variable-speed drive can be amplifier consisting of power differential 1, comparing differential 30, regulating differential 2, control differential 36 and two-self-braking mechanisms 3, 4. Input of power differential is connected with traction motor and input of regulating differential, central gears 17, 18 of power differential are connected with driven links 15, 16 of self-braking mechanism and with central gears 32, 33 of comparing differential to provided rotation of central gears of comparing differential in opposite directions. Driving links 13, 14 of self-braking mechanisms are connected with central gears 19, 20 of regulating differential and central gears 42, 43 of control differential to provide rotation of central gears of control differential in opposite directions, and change of gear ratio is carried out by means of bicycle-type pedal unit 46 mechanically coupled with control differential with possibility of changing speed of rotation of its central gears. Central of regulating differential are closed by speed equalizer 41. ^ EFFECT: provision of vehicle with ratio change and reversing by means of bicycle-type pedal drive. ^ 2 cl, 1 dwg |
