Abstract
A two-wheeled or three-wheeled vehicle which can increase the speed is provided, which is characterized in that: levers and groups of chain transmission devices are arranged on both sides of the vehicles. Through adding strength on the pedal, the lever stirs the great flywheel to work, after second chain transmission, the small chain wheel drives the large chain wheel and the large chain wheel then drives the small chain wheel to work. The transmission structure increases the transmission ratio and vehicle speed.
Description
Affiliated technical field
The utility model relates to a kind of two-wheeled or three-wheel vehicle, especially a kind of two-wheeled or three-wheel vehicle that raises speed with lever and chain gearing.
Background technology
At present, known two-wheeled or three-wheel vehicle are to make wheel rolling by sprocket wheel, chain gear, and the structure transmission of this car is single, the speed of a motor vehicle is slow, and be not satisfactory during use.
Summary of the invention
The purpose of this utility model is to change the part-structure of existing two-wheeled or three-wheel vehicle, and the two-wheeled or the three-wheel vehicle of a kind of lever and chain hybrid transmission is provided.
The technical solution adopted in the utility model is: many group chain sprocket drive and lever are set on two-wheeled or three-wheel vehicle stir the driving device of mode.By foot-operated circular movement, act on lever and stir big flywheel running, through the chain transmission minor sprocket at another position and coaxial hinge wheel are rotated again, its hinge wheel drives small flywheel on the rear wheel through chain gear again and rotates and realize above-mentioned purpose.
The above-mentioned two-wheel car that improves the speed of a motor vehicle is that two groups of big small flywheels, flower-drum are contained in respectively on the axle of rear wheel both sides, and two groups of big minor sprockets are contained in respectively on the axis of car both sides, and leverage power, the chain wheel set transmission by the car both sides improves the speed of a motor vehicle.
The above-mentioned three-wheel vehicle that improves the speed of a motor vehicle, be on the dilatory bar of three-wheel vehicle, to be provided with two axles, two big flywheels are contained in respectively on the one axle of car both sides, two groups of big minor sprockets are contained in respectively on its another axle of car both sides, two small flywheels are contained in respectively on the rear vehicle shaft of car both sides, and leverage power, the chain wheel set transmission by the car both sides improves the speed of a motor vehicle.
The beneficial effects of the utility model are: this drive mechanism has increased its transmitting ratio, can improve the speed of a motor vehicle, can be widely used in two taking turns, three-wheel vehicle.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of first embodiment one side of the utility model.
Fig. 2 is the structural representation of second embodiment one side of the utility model.
The specific embodiment
Embodiment 1
As shown in Figure 1, on two-wheel car rear wheel two side shafts respectively symmetry a big flywheel (1), a small flywheel (9), a flower-drum (13) be housed.For the ease of changing spoke, the diameter of flower-drum on the axle (13) is greater than small flywheel (9).On the axis of the both sides of car respectively symmetry a hinge wheel (7), a minor sprocket (6) be housed.The both sides of car also are provided with two chains (5), (8) and a lever (3) respectively.Lever (3) has an end to have bearing to be connected with an end of pedal crank (4), and the other end passes from sleeve (2), and the connecting lever place of sleeve (2) is fixed on the sidewall of big flywheel (1), and connecting lever has bearing in the place.In order to allow lever that certain transmission space is arranged, need pedal crank is increased and on pedal crank, be provided with foot-operated turn (10).
Embodiment 2
As shown in Figure 2, on the dilatory bar of three-wheel vehicle, be provided with two axles (11), (12).Two big flywheels (1) are contained in respectively on the axle (11) of three-wheel vehicle both sides, two hinge wheels (7), minor sprocket (6) respectively the symmetry the axle that is contained in the three-wheel vehicle both sides (12) on, two small flywheels (9) are contained in respectively on the rear vehicle shaft of car both sides.The both sides of car are respectively equipped with two chains (5), (8) and a lever (3).Lever on the three-wheel vehicle (3) has an end to have bearing to be connected with an end of pedal crank (4), and the other end passes from sleeve (2), and the connecting lever place of sleeve (2) is fixed on the sidewall of big flywheel (1), and connecting lever has bearing in the place.In order to allow lever that certain transmission space is arranged, need pedal crank is increased and on pedal crank, be provided with foot-operated turn (10).
By on stretcher, adding the masterpiece circular movement, acting on the big flywheel (1) that lever (3) is stirred on the two-wheel car rear wheel or three-wheel vehicle is drawn on the bar turns round, big flywheel (1) makes on the two-wheel car axis by chain (5) transmission again or three-wheel vehicle is drawn on the bar minor sprocket (6), hinge wheel (7) rotate, hinge wheel (7) drives small flywheel (9) through chain (8) transmission again and rotates, thereby can improve the speed of a motor vehicle.
