Abstract
The utility model belongs to the operation and transportation class, particularly relates to an improved center-of-gravity wheeled vehicle driven by the variation of the center-of-gravity of a human body. The utility model comprises a vehicle frame, a handlebar and vehicle wheels. The middle part of an upper frame is provided with a shaft fixed by two supports, the shaft is fixed with a foot pedal, the foot pedal can swing along the shaft, both ends of the foot pedal are respectively fixed with a fan gear, the fan gear is meshed with a rack bar fixed on the vehicle frame, and the rack bar drives a drive chain to cause a rear wheel to rotate. The utility model can convert left and right swing when the center-of-gravity of a human body moves into the rotation of the rear wheel, so as to cause the utility model has the advantages of labor saving, high running speed, etc.
Description
The utility model belongs to operation, transportation class, particularly relates to a kind of improved center of gravity vehicle that changes driving by the gravity center of human body.
Present human-powered vehicle has two-wheeled, tricycle, mainly is to drive by manpower, does not also drive by gravity center of human body's variation.
The purpose of this utility model provides a kind of vehicle that drives by gravity center of human body's variation.
The technical solution of the utility model is: a kind of gravity center vehicle, comprise vehicle frame, handlebar, wheel, it is characterized in that vehicle frame is to be linked to each other with underframe by upper frame to form, be fixed with one at the upper frame middle part by two supporting bases, on axle, be fixed with a stretcher, the stretcher two ends are fixed with elevating arc respectively, two elevating arcs respectively be fixed on upper frame both sides two tooth bars moving up and down and be meshing with each other, the tooth bar cross section is square tooth bar, on its two adjacent surface tooth is arranged, the engagement of tooth on the one side and elevating arc, the tooth on the another side is meshed with the gear of band ratchet device on being fixed on underframe, makes the trailing wheel rotation by this gear driven one messenger chain.Tooth bar is positioned by the supporting that is fixed on upper and lower framework both sides, and supporting can be sliding bearing or rolling bearing.
The utility model can change with the gravity center of human body, and makes the stretcher swing, thereby driving this car advances, and realizes the purpose that laborsaving moving velocity is fast.
Embodiment of the present utility model is explanation in detail in conjunction with the accompanying drawings.
Accompanying drawing 1 is the structural representation of the utility model master apparent direction.
Accompanying drawing 2 cuts open scheme drawing for the utility model A-A.
Accompanying drawing 3 cuts open scheme drawing for the utility model B-B.
Shown in accompanying drawing 1,2,3, vehicle frame is to be linked to each other and form by supporting 1 by upper frame 2, underframe 6, and underframe 6 front and back are fixed with two front vehicle wheels 4 and two rear wheels 22 respectively, are fixed with a messenger chain between two wheels.Be fixed with one 28 at upper frame 2 middle parts by two supporting bases 27, on axle 28, be fixed with a stretcher 8, be fixed with elevating arc 25 respectively at stretcher 8 two ends, two elevating arcs 25 respectively be fixed on upper frame both sides two tooth bars 7 moving up and down and be meshing with each other, tooth bar 7 is square for the cross section, on its two adjacent surface tooth is arranged, wherein tooth on the one side and elevating arc 25 engagements, tooth on the another side be fixed on underframe on messenger chain in gear 10 be meshed, driving axle I11 by gear 10 rotates, by miniature gears 13 engagements on big gear wheel on the axle 11 9 and the axle II14, miniature gears 16 engagements on big gear wheel 12 on the axle II14 and the axle III17, miniature gears 19 engagements on the big gear wheel 15 of axle on the III17 and the axle IV20, gear 21 engagements on the big gear wheel 18 on the axle IV20 and the axle V23 drive rear wheel 22 by axle V23 and rotate.The travel direction of this car is by axletree 3 that links to each other with front vehicle wheel 4 and handlebar 5 controls, and front vehicle wheel 4 is fixed on underframe 6 front portions by axle 3.Tooth bar 7 is supporting 24,26 supportings by being fixed on upper and lower framework both sides respectively, and this supporting 24,26 can be to slide or rolling bearing.The people stands on the stretcher 8, by moving of center of gravity, makes stretcher 8 along axle 28 swings, rotate thereby drive rear wheel by elevating arc 25, tooth bar 7 and messenger chain, and be the gear of a band ratchet device with tooth bar 7 pitch wheels 10 in the messenger chain wherein.
