FIELD: transport.SUBSTANCE: invention relates to collapsible four-wheelers. Rear drive wheels 1 allow scooter turns under control of joystick 32 thanks to difference in motor rpm. Front wheels 12 are driven elements. Frame is composed of linkage between rear wheel and front wheel leverage axle 22 to allow rotation of wheels relative to each other. Respectively, levers of front and rear wheels are spring-loaded relative to each other by resilient element. Levers of rear wheels are coupled with seat 9. In folded position, front and rear wheels are located on one axial lone. In acceleration, frame rear part with seat may be rearranged with frame front part.EFFECT: decreased overall dimensions and weight, higher speed.5 dwg |
