Abstract

Велосипед с эллиптическим приводом, включающий раму с рулем и седлом, колеса и привод с ведущей звездочкой, двумя шатунами и педалями, отличающийся тем, что привод состоит из закрепленного в корпусе элемента эллиптической формы, имеющего профиль сечения двутавр, внутренняя эллиптическая поверхность которого образует рабочую дорожку с зубчатым профилем, и педального механизма, содержащего корпус, в котором закреплены на своих валах рабочая шестерня, находящиеся с ней в зубчатом зацеплении две прижимные шестерни с винтовым регулятором нагрузки и натяжные ролики, причем педальный механизм установлен на элементе эллиптической формы с возможностью перемещения по зубчатой поверхности рабочей дорожки за счет натяжных роликов, снабженных упругими элементами и зубчатого зацепления рабочей шестерни с поверхностью рабочей дорожки, при этом вал рабочей шестерни, закрепленный в корпусе педального механизма с возможностью вращения, выполнен полым и сквозь него проходит вал ведущей звездочки, оба вала соединены ступенчатой муфтой, один конец которой установлен на валу ведущей звездочки с возможностью осевого перемещения, образуя с этим валом шлицевое соединение, второй конец ступенчатой муфты установлен с возможностью образования с внешней поверхностью вала рабочей шестерни замковое соединение для передачи крутящего момента от вала звездочки на вал шестерни и снабжен возвратной пружиной, корме того, шатуны одним концом закреплены на валу ведущей звездочки, а к другому концу прикреплены педали.A bicycle with an elliptical drive, including a frame with a steering wheel and a saddle, wheels and a drive with a drive sprocket, two connecting rods and pedals, characterized in that the drive consists of an elliptical element fixed in the body, having a cross-section profile of an I-beam, the inner elliptical surface of which forms a work path with a gear profile, and a pedal mechanism comprising a housing in which the working gear is fixed on its shafts, two pressure gears with a screw adjuster loads and tension rollers, and the pedal mechanism is mounted on an elliptical element with the ability to move along the gear surface of the working track due to the tension rollers equipped with elastic elements and gear engagement of the working gear with the surface of the working path, while the shaft of the working gear mounted in the housing of the pedal mechanism rotatable, made hollow and the drive sprocket shaft passes through it, both shafts are connected by a stepped clutch, one end of which is mounted on the drive sprocket shaft riders with the possibility of axial movement, forming a spline connection with this shaft, the second end of the step clutch is installed with the possibility of forming a lock connection with the outer surface of the working gear shaft for transmitting torque from the sprocket shaft to the gear shaft and is equipped with a return spring, furthermore, connecting rods at one end mounted on the shaft of the drive sprocket, and pedals are attached to the other end.
