Abstract
The car beam of handlebar shift-forward type bicycle is provided with driver train, handlebar, front-wheel, seat and trailing wheel from front to back successively, driver train be positioned at car beam front end and by chain drive trailing wheel, it is characterized in that handlebar and front fork are off formula structure, the two is connected with car beam respectively by respective steering tube, handlebar is positioned at the front of front fork, and handlebar is connected with front fork by connecting rod and bearing pin.Front fork and front-wheel steering is driven by connecting rod and bearing pin when handlebar rotates.This programme has innovated the structure of driver train at front low position, keeping under the prerequisite that bodywork length is constant, increase the distance between handlebar and seat, make to get on or off the bus convenient, and have that vehicle body is short, center of gravity is low and chair type bicycle pedal power greatly, the advantage of brisk laborsaving and ride comfort by bike.
Description
Technical field
The utility model belongs to a kind of manpower transportation field, is specially a kind of bicycle.
Background technology
The driver train of chair type bicycle is generally all positioned at the front portion of car body, so that the backrest of seat is played a supporting role to power to pedal forward, thus is conducive to pedaling out larger propulsive effort, makes more brisk and laborsaving by bike.The type of drive of this car is divided into f-w-d and back-wheel drive two kinds, and existing deficiency is: the propulsive effort interference front-wheel steering of f-w-d mode, causes manipulation difficulty and driving shakiness; For back-wheel drive mode, the position of driver train has three kinds, and one is the structure being positioned at front-wheel rear, and car body is longer, is inconvenient to carry and deposit; Two is the structures be positioned at above front-wheel, and center of gravity is higher, and driving is unstable; Three is the structures being positioned at front, and handlebar hinders and gets on or off the bus, and uses inconvenience.Because these are not enough, cause chair type bicycle to be used widely, chair type bicycle brisk labour-saving advantage do not have yet be effectively played.
Summary of the invention
The purpose of this utility model is exactly to solve above-mentioned deficiency, provide that a kind of car body is compact, center of gravity is lower, easy for going up and down, manipulation easily and brisk labour-saving chair type bicycle of riding.
Embodiment of the present utility model is as follows:
Car beam is provided with driver train, handlebar, front-wheel, seat and trailing wheel from front to back successively, driver train be positioned at car beam front end and by chain drive trailing wheel, it is characterized in that handlebar and front fork are off formula structure, the two is connected with car beam respectively by respective steering tube, handlebar is positioned at the front of front fork, and handlebar is connected with front fork by connecting rod and bearing pin.Front fork and front-wheel steering is driven by connecting rod and bearing pin when handlebar rotates.
This programme has innovated the bicycle of back-wheel drive, driver train is in the structure of front low position, keeping under the prerequisite that bodywork length is constant, increase the distance between handlebar and seat, make to get on or off the bus convenient, and have that vehicle body is short, center of gravity is low, convenient in carrying and pulsation-free feature of riding, also have chair type bicycle pedal power greatly, the advantage of brisk laborsaving and ride comfort by bike.
