Abstract

The utility model discloses a front-rear speed-change disc-brake driving bicycle. The front-rear speed-change disc-brake driving bicycle is based on an existing bicycle, and the structure of the existing bicycle is not changed. Speed change devices are mounted on a front wheel and a rear wheel, disc brake devices are mounted on the front wheel and the rear wheel, and driving devices are mounted on the front wheel and the rear wheel. Due to the fact that the driving devices are mounted both on the front wheel and the rear wheel, all hand-foot disabled people can ride on the bicycle. The front-rear speed-change disc-brake driving bicycle is large in gradeability, high in riding speed and saving in labor, thereby being a bicycle with the characteristics of the times.

Description

Front and back speed change disc brake drives bicycle

Technical field

The utility model relates to a kind of bicycle that people like, especially a kind of front and back speed change, disc brake, driving bicycle.

Background technology

Inner in " bikedom ", the bicycle of China is preeminent, with high content of technology because of a great variety of models, quantity, and superior performance is described as " bikedom ".But in " bikedom " inner blemish in an otherwise perfect thing in addition, for example: also not with putting in place, transmission system, actuating device with high content of technology are not fully utilized the disc brake apparatus of function admirable, and potential does not fully excavate; Although the great variety of models of bicycle, the viewpoint from development awaits to constantly bring forth new ideas, the beautify life management philosophy, and is remarkable so that more qualities to be provided, the new bicycle with characteristics of the times.

Summary of the invention

The purpose of this utility model is intended to overcome the prior art deficiency and constantly promotes the bicycle quality, and provide a kind of front and back speed change disc brake to drive bicycle, this bike tech content is high, superior performance, fashionable, speed is laborsaving again soon, is the new bicycle with characteristics of the times.

For achieving the above object, before and after the utility model, speed change disc brake driving bicycle is achieved by the following technical solutions:

Before and after the utility model, the speed change disc brake drives bicycle, is characterized in that front-wheel is installed front-wheel drive, trailing wheel is installed back wheel driving gear, and front axle is installed disc brake apparatus, disc brake apparatus after rear axle is installed, and transmission system before front-wheel is installed, trailing wheel is installed rear derailleur; Described front-wheel drive is by filling cranked front wheel driving shaft (hereinafter to be referred as bent drive axle) drive sprocket set, chain, driven chain wheels, front transmission system (hereinafter to be referred as front change device) formation, drive sprocket set is connected on bent drive axle, and bent drive axle is connected on handle, chain circularizes closed the connection on drive sprocket set and driven chain wheels and front change device.Described front change device comprises adjuster, change-speed box; Above-mentioned drive sprocket set is made of more than one sprocket wheel.

Comprehensive technique scheme can be found out this bicycle, and therefore forward and backward disc brake apparatus, transmission system, the actuating device of all using is disc brake variable speed drive (VSD) bicycle before and after claiming.

Before and after the utility model, disc brake variable speed drive (VSD) bicycle has the following advantages:

One, because front and back are equipped with disc brake apparatus, bicycle brake is clever, reliable, need not often keep in repair, and steel ring can not wear and tear;

Two, because front and back wheel is all installed transmission system and actuating device, bicycle speed is fast, and the people is laborsaving, easily, when especially climbing and frontal resistance are large, transmission system and front and back actuating device before and after opening, more even better than other bicycle;

Three, due to the structure that there is no to change existing bicycle, and adopt the disc brake apparatus of with high content of technology, reliable operation, superior performance, transmission system, actuating device, thereby make this bicycle, and there is no much difficulties, be easy to turn one's hand over.Simultaneously, cost is low, and good Social benefit and economic benefit is arranged.

Description of drawings

Fig. 1 is the front view that front and back speed change disc brake drives the structural representation of bicycle;

Fig. 2 is that the A of the front and back speed change disc brakes structural representation that drives bicycle is to view.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

The utility model is on the basis of existing back wheel driving gear bicycle, at front-wheel, a front-wheel drive is installed again, perhaps on existing front-wheel drive bicycle, at trailing wheel, an actuating device is installed, no matter be which kind of style bicycle front and rear wheel has actuating device like this, leg, pin, the handicapped people of foot, can with the hands operate front-wheel drive, the same bicycle ridden, the handicapped people of hand, can with leg foot stepping bicycle, can ride bicycle in the same old way.

Referring to Fig. 1, Fig. 2, described front-wheel drive is to be made of crank 1 bent drive axle 2, drive sprocket set 12, chain 5, driven chain wheels 8, front change device, drive sprocket set 12 is connected on bent drive axle 2, bent drive axle 2 is connected on handle 3, and chain 5 circularizes closed drive sprocket set 12 and driven chain wheels 8 and the front change device of connecting; Described front change device comprises adjuster 4, change-speed box 9; Described chain wheel set is to be combined by more than one sprocket wheel;

Described back wheel driving gear is by the drive sprocket set 12 that is connected on axis, and the driven chain wheels 8, rear derailleur, the chain 5 that are connected on rear axle form, and chain 5 circularizes closed drive sprocket set 12, driven chain wheels 8 and the rear derailleur of connecting; Described rear derailleur is made of adjuster 4, change-speed box 9.Rear disc brake apparatus 7 is connected on rear axle, and front disc brake apparatus 6 is connected on front axle.

The driving principle of described front driving device is operating crank 1 with the hands, produces moment bent drive axle 2 constantly rotated, thus drive drive sprocket set 12, by chain 5 carry-over moments, order about driven chain wheels 8 and constantly rotate, impel front-wheel constantly to roll forward, bicycle is operation forward constantly; Just self-evident as for its driving principle of rear drive equipment.

Claims

1. a front and back speed change disc brake drives bicycle, its characteristics are that front-wheel is equipped with front-wheel drive, trailing wheel is equipped with back wheel driving gear, and front axle is equipped with disc brake apparatus, rear axle is equipped with disc brake apparatus, the front transmission system of front-wheel installation, and trailing wheel is installed rear derailleur; Described front-wheel drive by bent drive axle, drive sprocket set, chain, driven chain wheels, front transmission system consist of, drive sprocket set is connected on bent drive axle, bent drive axle is connected on handle, and chain circularizes closed drive sprocket set and driven chain wheels and the front transmission system of connecting.
