Abstract
The utility model relates to a scooter which is driven by foot stepping and changes speed by the driving motion of the gear set, being used for entertainment and bodybuilding or used as small-sized vehicle. The gear set is driven by an arc rack connected with a pedal to change speed, and the weight of human body is conversed into driving force. The utility model which is portable has small volume and low center of gravity, thereby achieving strong stability, and the person who stands on the scooter can ride fast or slowly, or stop.
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, by chain gear, the front and back wheel of car is bigger, and car body is also relatively large, move and carry inconvenience, can not enter shopping mall, square, supermarket, the access vehicle is cumbersome.A kind of Kickboard Scooter that is used for amusement is arranged at present, and volume is very little easy to carry, slides but will pedal by leg, does not drive transmission system, and speed is slow, can not use as the vehicle.
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 purpose of this utility model is achieved in that three wheels that have that this car contacts with ground, and front-wheel links to each other with handlebar and controls direction, and the back two-wheeled is driven by variable gear and advances.Two pedals are connecting tooth bar by connecting rod about having on this car, by spring wire tooth bar and pedal are popped up, and can bounce automatically after making it step on and lift pin.Rack drives be two bidentates wheels, they are on same anchor shaft, this bidentate wheel is the ratchet structure by the unidirectional drive bull wheel of steamboat, similar with the flywheel of bicycle, the steamboat of stepping on hour rack engagement bidentate wheel under the pedal drives bull wheel and rotates, when pedal pops up, the steamboat revolution does not drive bull wheel, bull wheel is only done unidirectional rotation, driving two miniature gearss in addition on the another thereafter axle, is coaxial big gear wheel in the middle of two gears, and these last three gears are fixed on the axle, coaxial rotation together, gear broad in the middle again with rear vehicle shaft on pinion, this miniature gears also is a kind of single direction ratchet, is equal to bicycle freewheel, but its driving cog is wheel tooth but not chain tooth, and final drive axle is rotated forward.
The utility model is owing to adopt the gear cluster transmission gear shift, and compact conformation utilizes human body weight to stand and tramples driving, do not establish vehicle seat, reduced the car body size to greatest extent, so this car car body is little, in light weight, speed is very fast, portably use conveniently, can go slowly again by fastrunning by trampling control.
The utility model proposes the most preferred embodiment of structure below in conjunction with description of drawings.
Accompanying drawing is a schematic perspective view, and (1) is front-wheel among the figure, and (2) are trailing wheel, front-wheel (1) links to each other with handlebar (3), tooth bar (5) is arranged below the pedal (4), be shaped as one section circular arc, be fixed in the car body front end through delta link (6), but axial rotation, spring wire (7) twists in the car front end connecting rod (6) is popped up, and there is projection tooth bar (5) lower end, prevents the disengaging that upspringed, its length is less than radius of wheel, in order to avoid contact to earth after depressing.Following pedal (4), tooth bar (5) drives bidentate wheel (8) and goes up rotation at front axle (9), driving the miniature gears (11) that is fixed on the axis (10) again rotates, big gear wheel (12) on the axis (10) is also rotated thereupon, drive the ratchet (14) on the rear axle (13), make rear axle (13) rotating drive trailing wheel (2) forward.Bidentate wheel (8) and ratchet (14) all are ratchet structures, identical with bicycle freewheel, when lifting pin again like this after pedal (4) is stepped on, spring wire (7) drivening rod (6) tooth bar (5) is replied, and only drives the steamboat revolution on the bidentate wheel (8) and bull wheel does not change.When car when sliding, rear axle (13) rotates, the ratchet on it (14) does not then change.The steering column jacket of car front center and car (15) weld together, front axle (9) is an anchor shaft, axis (10) and rear axle (13) they are turning cylinders, all wear to be connected on the both sides steel plate (16), constitute change-gear set and car body.
Claims (5)
1,, it is characterized in that pedal (4) connects tooth bar (5) driven gear group transmission and speed change, travels car with the foot-driven scooter.
2, according to described this device of claim 1, it is characterized in that the tooth bar (5) of arc links to each other with connecting rod (6), fix and can axially rotate at front end, pop up by spring (7).
3,, it is characterized in that the bidentate wheel (8) that tooth bar (5) drives on the front axle (9) rotates according to described this device of claim 1.
4, according to described this device of claim 1, it is characterized in that gear cluster axis (10) both sides are miniature gears (11), the centre is big gear wheel (12), wheel shaft is with changeing.
5, according to described this device of claim 1, it is characterized in that on the gear cluster rear axle (13) ratchet (14) directly and big gear wheel (12) engaged transmission on the axis (10).
