Description
Technical field
The utility model relates to a kind of bicycle, specifically, relates to a kind of front-drive bicycle.
Background technology
At present, bicycle popular on the market generally adopts the rear drive mode, this bicycle generally increases tractive performance by speed-changing mechanism, people have carried out diversified improvement at this traditional bicycle structure, the mechanism form of bicycle is more and more, satisfied all ages and classes, the demand and the use of different customers and difference in functionality, if any transmission device change other rear drive mode into, for example worm drive or curved bar transmission, the employing before driving mode that also has, but these improve basic still the employing and only utilize foot-operated mode that power is provided, Xiang Guan structure and design simultaneously is difficult to do bigger improvement, as people by bike the time, both hands are responsible for handling handlebar generally speaking, foot scrunches pedal power is provided, because the bicyclist is downwards to pedal, the seat of bicycle also needs design-calculated than higher, the center of gravity of whole like this people's truck system is also than higher, upper body must be taked forward lean when riding, can oppress both arms like this, usually cause backache, uncomfortable situations such as arm acid are easy to generate fatigue.
Summary of the invention
The purpose of this utility model provides low, stable, comfortable, the fireballing a kind of front-drive bicycle of a kind of center of gravity.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of front-drive bicycle, comprise vehicle frame, front vehicle wheel, rear wheel, it is characterized in that: the front portion of described front vehicle wheel is provided with drive wheel, be provided with fixing support rack between described drive wheel and the vehicle frame, described drive wheel is fixedly supported on the leading section of described fixing support rack by turning cylinder, the outside of described front vehicle wheel is provided with rotary flywheel, has rotary connecting device between described rotary flywheel and the front vehicle wheel, be connected with driving chain between described drive wheel and the rotary flywheel, the front portion of described vehicle frame is provided with rocking bar, described rocking bar and vehicle frame are hinged, the upper end of described rocking bar is provided with handle, and the lower end of described rocking bar is provided with pedal, is provided with crankshaft-link rod between described rocking bar and the drive wheel.
Be the utility model technical scheme more specifically below:
Described drive wheel is arranged on a side of vehicle frame, and the opposite side of described vehicle frame is symmetrically arranged with second fixing support rack, and the front end of second fixing support rack and drive wheel correspondence position are provided with second drive wheel, and described second drive wheel is connected with the drive wheel coaxial rotation.
Described fixing support rack comprises upper support bar, the lower support bar that is fixed on the vehicle frame front portion, and described upper support bar, lower support bar and vehicle frame form the triangle fixing support rack.
Described drive wheel, rotary flywheel are variable gear.
Described handle is provided with brake.
Be set with seat, backrest on the described vehicle frame.
Described vehicle frame is provided with the bracing frame that is used for supporting bicycle.
The rear portion of described vehicle frame is provided with luggage carrier, goods-container.
Described drive wheel, second drive wheel be provided with the protection watt.
Beneficial effect: the utility model adopts above technical scheme, compares with existing technical scheme to have the following advantages:
(1) drive wheel is installed on the front-wheel, has changed traditional pedal mode, shortened the distance between the front and rear wheel, meet the structure of human body more.
(2) upper and lower side of rocking bar is respectively equipped with handle and pedal, can be separately drives bicycle with hand or pin, also can use both hands and feet to drive bicycle and move ahead, and has increased the power of bicycle, and more convenient to use, handle has steering-effecting simultaneously.
(3) because drive wheel is arranged on the front-wheel place, so with the reach in force the height of seat can be reduced, whole center of gravity reduces, reduced resistance, the face area of seat can increase, and is more comfortable in the time of by bike, be not easy to produce sense of fatigue, the time of riding can be longer, improved the usefulness of bicycle.
(4) on the drive wheel protection watt setting, can play protective action when riding, improved safety performance.
(5) setting of variable gear has improved the running velocity of bicycle.
The utility model is described in further detail below in conjunction with drawings and Examples.
