Abstract

The utility model relates to a double driven bicycle which is characterized in that a back wheel hub is installed in back wheel inverse hanging type bearings and rotates inside. Back wheels are installed in the back wheel hub and rotate inside. The left side of a back shaft is provided with a small toothed disk, and the left side of a centre shaft is provided with a flywheel. The small toothed disk and the flywheel are linked by chains. The back wheels adopt inverse hanging type bearing seat structure, and the centre distance between the centre shaft and the back shaft is 650 millimeters. The utility model has four functions of two-person double driving, two-person single-driving, one-person single-driving and the bracket for transporting cargo. The utility model has the advantages of good stability, good maneuverability, light weight, convenient operation, labor saving, high speed, simple structure, low cost, no energy source, no pollution, convenient repair, etc.

Description

Double driven bicycle

The utility model relates to the drive mechanism of bicycle, adopts twin shaft, two strands, double-drive device.

Existing bicycle is single shaft, strand, single drive mechanism that drives, and significant disadvantages is that speed is slow, effect is single, bicycle band people's problem often occurs; And motor scooter cost height, fuel anxiety, costliness are maintained general family difficulty, heavy inconvenient carry it upstairs, and general family does not have garage.

The purpose of this utility model is to draw the advantage of Bicycles and Motorcycles, has overcome the shortcoming of Bicycles and Motorcycles, solves bicycle band people's problem, and the double-drive device of bicycle is provided.This device can reach double pair of driving, double single driving, single single driving, four kinds of functions of carriage shipping goods.

The purpose of this utility model is achieved in that rear axle and trailing wheel flower-drum, trailing wheel reversely hung Yong bearing seat are concentric, and rear axle is installed in the trailing wheel flower-drum, and rotates therein, and the trailing wheel flower-drum is installed in the reversely hung Yong bearing block bearing, and rotates therein.When, axis motionless when rear axle rotated, its transmission principle was identical with ordinary bicycle, can be single singly drives, also can double single driving; When axis, rear axle rotated simultaneously, bicycle rear axle was by the little chain wheel in left side.The left side chain passes to the flywheel in axis left side, drives axis and rotates, and adds the direct drive of axis itself, drives the large toothed disk on axis right side, and the flywheel that drives trailing wheel flower-drum right side by chain rotates forward, and bicycle advances, and reaches the purpose of double driving.

Concrete structure of the present utility model is drawn by the following drawings, and accompanying drawing is according to the section of structure that the utility model proposes.Below in conjunction with details and the service condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

This device is to install flywheel additional in the left side of existing bicycle middle shaft (8), and rear axle (4) and ball bearing of main shaft (2) are housed in trailing wheel flower-drum (3); Trailing wheel flower-drum (3) and ball bearing of main shaft (7) are installed in the trailing wheel reversely hung Yong bearing seat (6), and hind axle bearing (6) is hung upside down at vehicle frame trailing wheel position, and the little chain wheel (1) on the rear axle (4) joins by the flywheel in left side chain and axis (8) left side; The flywheel (5) that the large toothed disk on axis (8) right side is gone up the right side by right side chain and trailing wheel flower-drum (3) connects, and axis (8) is 650 millimeters with the width between centers of rear axle (4).The seat, front and back is a monoblock oblong spring sofa seat.
