Abstract
The utility model relates to a gear-driven variable speed scooter, which is driven by foot and used for leisure and fitness or as a small vehicle; wherein, two chains connected by a pedal drive a gear into variable speeds reciprocatingly, and convert the gravity of human body into a driving force. The utility model has the advantages of compact size, portability, low center of gravity of the scooter and high stability; therefore, users can travel fast or slow by treadling the scooter with different forces.
Description
The utility model relates to and a kind ofly driving so that gear change is foot-operated, is used for entertainment body-building or as the scooter of the vehicle.
Now very universal by the foot-driven bicycle and since the people be above being sitting in to pedal, ride laborsaving but legpower is little, the front and back wheel of car is bigger, car body is also relatively large, moves and carries inconvenience, can not enter shopping mall, square, supermarket, a kind of Kickboard Scooter that is used for amusement is arranged at present, volume is very little easy to carry, slides but will pedal by leg, does not drive transmission system, speed is slow, can not use as the vehicle.My previous " a kind of gear-driving speed-variable scooter " application number that proposes is 022322272, and present patent application is the another kind of form of its drive mechanism.
It is very fast that the purpose of this utility model provides the little speed of a kind of car body, utilizes human body weight to trample the scooter of driving with both feet, be easy to carry, but both entertainment body-buildings, again can be as small vehicles.
The utility model is achieved in that this car is a tricycle structure, and front-wheel links to each other with handlebar by front-fork and steering shaft sleeve pipe and controls direction, and the back two-wheeled is directly driven by variable gear by axletree and advances.Two pedals about this car has, by two short chains of connecting rod pulling, the chain other end is pulled upwardly the connecting rod pedal by the extension spring traction, make its step on and lift pin after can lift automatically.Two chains drive respectively is two and goes up on same axle sleeve with the flywheels that turn to, in the middle of two flywheels is a coaxial big gear wheel, two flywheels can drive the big gear wheel unidirectional rotation respectively, the big gear wheel ingear is another steamboat of going up the bidentate wheel, the bull wheel of bidentate wheel again with axletree on fixing pinion, drive axletree and rotate car is advanced.
The utility model is owing to adopt gear cluster speed change through-coupling, wheel is little but rotating speed is fast, body gravity is low, compact conformation makes full use of human body gravity and stands and trample driving, has reduced the car body size to greatest extent, so this car car body is little in light weight, speed is very fast, portably uses conveniently, can go slowly again by fastrunning by trampling control.
The most preferred embodiment that the utility model proposes below in conjunction with description of drawings.
Accompanying drawing is a structural representation of the present utility model, handlebar among the figure (1) is controlled front-wheel (3) by steering column jacket (2) and is turned to, vehicle frame (4) front end is fixed on the steering column jacket (2), the both sides, rear end are fixed with bearing carrier ring (5) axle tree (6) and trailing wheel (7), the gear cluster both sides are fixedly stood on vehicle frame (4) rear portion axletree (6) by steel plate and are located, the connecting rod (9) of pedal (8) is fixed in the tailstock by rotating steadying bar (10), connecting rod (9) inboard has cross out one section to link to each other with chain (11) one ends, and there is extension spring (12) vehicle frame (4) bottom by track adjusting wheel (13) pulling chain (11) other end.Left-hand tread plate among the figure (8 ') is stepped on, pulling left side chain (11 ') drive flywheel (14) and middle big gear wheel (15) are rotated downwards, the bidentate wheel (16) that is engaged with rotates, and drives axletree (6) simultaneously and goes up fixing miniature gears (17) rotation, axletree (6) and wheel (7) is rotated advance.When left foot lifts right threading following time, left side extension spring (12 ') pulling left side chain (11 ') lifts left-hand tread plate (8 ') connecting rod (9 '), at this moment, left side flywheel (14) revolution, the right side flywheel drives gear broad in the middle (15) and rotates, though both sides flywheel backward rotation but be independent of each other, gear broad in the middle (15) is only done unidirectional rotation.Car is when sliding, and the miniature gears (17) on the axletree (6) drives bidentate wheel (16) and big gear wheel (15) is only done idle running, and the chain (11 ') on the flywheel (14) can not driven.
Claims (5)
1, with the foot-driven scooter, handlebar (1) vehicle frame (4) pedal (8) front-wheel (3) axletree (6) and two trailing wheels (7) are arranged, it is characterized in that stepping on pedal (8) connecting rod (9) and make back and forth pulling of continuous chain (11), transmission of driven gear group and speed change are travelled car.
2, according to described this car of claim 1, what it is characterized in that being driven by chain (11) is big gear wheel (15) to be arranged in the middle of two coaxial flywheels (14).
3,, it is characterized in that the big gear wheel (15) of unidirectional rotation in the gear cluster meshes the steamboat that another axle is gone up bidentate wheel (16) according to described this car of claim 1.
4,, it is characterized in that being fixed with on the axletree (6) miniature gears (17) is directly taken turns (16) with bidentate bull wheel engaged transmission according to described this car of claim 1.
5, according to according to described this car of claim 1, it is characterized in that pedal (8) connecting rod (9) drives chain (11) and replied through track adjusting wheel (13) pull-up by extension spring (12).
