Abstract
The invention relates to a bicycle with a forward shifting handlebar. A driving mechanism, the handlebar, a front wheel, a saddle and a rear wheel are sequentially arranged on a bicycle beam from front to back, and the driving mechanism is arranged at the front end of the bicycle beam and is used for driving the rear wheel by a chain. The bicycle is characterized in that the handlebar and a front fork have a breaking type structure and are respectively connected with the bicycle beam by a steering tube; the handlebar is arranged in front of the front fork and is connected with the front fork by a connecting rod and a pin shaft; when the handlebar is rotated, the front fork and the front wheel are driven to steer by the connecting rod and the pin shaft. According to the scheme, a structure that a driving mechanism is arranged at a lower part in front of a front wheel is innovated, and the distance between the handlebar and the saddle is prolonged on the premise that the length of a bicycle body is unchanged, so that a person can conveniently get on and off the bicycle, and the seat-type bicycle has the advantages of being short in bicycle body, low in center of gravity and large in pedaling force, and enabling a user to ride easily with less labor and feel comfortable when riding.
Description
Technical field
The invention belongs to a kind of manpower transportation field, be 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 plays a supporting role to power to pedal forward, thereby is conducive to pedal out larger propulsive effort, makes more brisk and laborsaving by bike.The type of drive of this car is divided into two kinds of f-w-d and back-wheel drives, and existing deficiency is: the propulsive effort of f-w-d mode disturbs front-wheel steering, causes manipulation difficulty and driving unstable; For back-wheel drive mode, the position of driver train has three kinds, and the one, be positioned at the structure at front-wheel rear, car body is longer, is inconvenient to carry and deposit; The 2nd, be positioned at the structure of front-wheel top, center of gravity is higher, and driving is unstable; The 3rd, be positioned at the structure in front-wheel front, handlebar hinders and gets on or off the bus, and uses inconvenient.Due to these deficiencies, cause chair type bicycle to be used widely, the brisk labour-saving of chair type bicycle advantage do not have yet be effectively played.
Summary of the invention
Object of the present invention is exactly in order to solve above-mentioned deficiency, provide that a kind of car body compactness, center of gravity are lower, easy for going up and down, manipulation easily and the brisk labour-saving chair type bicycle of riding.
Embodiment of the present invention are as follows:
Driver train, handlebar, front-wheel, seat and trailing wheel are installed on car beam from front to back successively, driver train is positioned at the front end of car beam and passes through chain drive trailing wheel, it is characterized in that handlebar and front fork are breakaway-element structure, the two is connected with car beam by steering tube separately respectively, handlebar is positioned at the front of front fork, and handlebar is connected with front fork by connecting rod and bearing pin.When rotating, handlebar drives front fork and front-wheel steering by connecting rod and bearing pin.
This programme has been innovated the bicycle of back-wheel drive, driver train is in the structure of front-wheel 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 the pulsation-free feature of riding, also have advantages of chair type bicycle pedal power greatly, brisk laborsaving and ride comfort by bike.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
See Fig. 1.Crank-drive mechanism 1 is positioned at the front end of car beam 2, is connected and drives trailing wheel by chain 12 with trailing wheel 11.Track adjusting wheel 13 is to 12 guide-localizations of chain and tension.Chain 12 tops are provided with chain guard 17.Front-wheel 15 is connected with car beam with front fork steering tube 6 by front fork 14.Handlebar 4 is positioned at the front of front-wheel, is connected with car beam by handlebar steering tube 3.The lower end of handlebar is provided with spindle arm 16, and spindle arm is connected with front fork by connecting rod 5 and bearing pin.Seat 8 is connected with car beam by telescopic tube 7 and can oscilaltion.Trailing wheel 11 is positioned on rocking frame 10, and rocking frame is connected with car beam with bearing pin by bumper 9.
Fig. 2 is the structural representation with multiplying wheel.Multiplying wheel 18 is connected with rocking frame 10 by support 19.The big gear wheel of multiplying wheel 18 is connected with trailing wheel by chain, and miniature gears is connected with crank-drive mechanism by chain.This structure is conducive to improve the road speed of BMX (Bicycle Motocross).
