Abstract

Изобретение относитс  к транспортному машиностроению, а именно к велосипе- достроению. Цель изобретени  - снижение массы рамы велосипеда. Рама велосипеда содержит верхний 1 и нижний 2 дугообразные стержни, выполненные в виде дуг окружностей и соединенные в передней и задней част х с образованием узлов креплени  управл емого колеса, заднего колеса, седла и каретки педального привода. Стержни 1 и 2 ст нуты между собой спицами 12, которые одним концом креп тс  во втулках 7 и 8, а другим - в стержн х 1 и 2 с возможностью регулировки их нат жени . 9 ил.FIELD OF THE INVENTION The invention relates to a transport engineering, in particular to a bicycle under construction. The purpose of the invention is to reduce the mass of the bicycle frame. The bicycle frame contains the upper 1 and lower 2 arcuate rods made in the form of circular arcs and connected in the front and rear parts with the formation of attachment points for the steerable wheel, rear wheel, seat and pedal drive carriage. The rods 1 and 2 are stitched together by the spokes 12, which are fastened at one end in sleeves 7 and 8, and the other end in rods x 1 and 2 with the possibility of adjusting their tension. 9 il.
