Abstract
The utility model relates to a portable type bicycle with concentric different axles. The utility model is characterized in that wheels are composed of a main wheel (1) and a guide wheel (2), load is supported by the main wheel (1), and the diameter of the guide wheel (2) is smaller than the diameter of the main wheel (1). A device with concentric different axles is adopted by the wheel hub of the main wheel (1), the device with the concentric different axles is that an inner layer is a pedal drive axle, a middle layer is a support hollow axle (12), and an outer layer is the wheel hub (10) and a tooth-shaped fly wheel (11), wherein, the two ends of the support hollow axle (12) can be fixedly connected with a frame, and balls or rollers (needles) are adopted to support and separate the three layers of concentric axles. A gear wheel is adopted to directly drive. The utility model has the advantages of short vehicle body, light weight and simple structure. The weight and the cost of the portable type bicycle with the concentric different axles are at least reduced more than quarter than the known bicycle.
Description
The utility model relates to a kind of bicycle, the special hand-held design concentrical and epitaxial bicycle that is used for the household tourism that adapts to.
Traditional bicycle is because vehicle body is long, and particularly the step gear separates with the long distance of driven flywheel, makes the own wt of vehicle body big, and the cost height is not suitable for the usefulness of city dweller and tourism very much.Even newly-designed Folding Bicycle is because basic structure is identical with standard bicycle, so car weight and cost all can't thoroughly reduce.
The purpose of this utility model is to propose a kind of novel, light, inexpensive more concentrical and epitaxial bicycle, overcomes the defective of known bicycle.The concentric different shaft drive that employing integrally combines makes the car weight of bicycle and cost reduce by 1/4th at least than present various bicycles.The shorter and smaller dexterity of vehicle body, it is more convenient to get on and off, and uses effect to be better than known bicycle.Simple in structure, can with the supporting production in enormous quantities of traditional processing technology.
The utility model is a kind of concentrical and epitaxial bicycle, and its principal character is: its wheel is made up of main wheel and track adjusting wheel, the main wheel support loading.Adopt concentric different shaft device in the main wheel hub, promptly internal layer is the step imput shaft, and the middle level is for supporting hollow shaft, skin is wheel nave and profile of tooth flywheel, separates with ball or roller (pin) supporting between three layers, adopts direct geared, abolish traditional big vehicle frame, adopt short square vehicle frame.
Solution of the present utility model can be described in more detail in conjunction with the following drawings.
Fig. 1 is a concentrical and epitaxial bicycle assembling scheme drawing.
Fig. 2 is the concentric different shaft device section-drawing of bicycle.
Fig. 3 is the concentric different shaft device lateral plan of bicycle.
Fig. 4 is the concentric different axle power drive scheme drawing of bicycle.
With reference to Fig. 1, the wheel of the utility model concentrical and epitaxial bicycle is made up of main wheel (1) and track adjusting wheel (2).Main wheel (1) wheel hub is outer can be the bicycle quick of all kinds of diameters in the tradition, and main wheel (1) mainly plays support loading.The diameter of track adjusting wheel (2) is less than or equal to main wheel (1), preferably adopts the path wheel.In the outside, main wheel (1) axle center gear case (3) is housed.Little triangular frame (4) bifurcated connects the both sides, axle center of main wheel (1), and wherein a side can connection gear case (3), and little triangular frame (4) is at the front upper side of main wheel (1), and stressed center of gravity is on main wheel (1).A stool (7) is housed on the little triangular frame (4).What flexibly connect with little triangular frame (4) is pilot bar (6), and pilot bar (6) upper end connects handle (5), and the lower end bifurcated connects track adjusting wheel (2).
Concentric different shaft device with reference to Fig. 2, Fig. 3, Fig. 4.It is a principal character of the present utility model.In this device, imput shaft (8) supports hollow shaft (12), and wheel nave (10) and profile of tooth flywheel (11) are concentric.Wherein, supporting hollow shaft (12) can captive joint gear case (3) or little triangular frame (4).Adopt ball or roller (pin) supporting to separate between three layers of concentric shafts.Concrete structure is: driving gear (9) is housed on the imput shaft (8), and step crank and tread plate can be adorned in imput shaft (8) two ends, and this structure is identical with traditional step device.Outermost layer in imput shaft (8) is cycle hub (10) and profile of tooth flywheel (11), and the diameter of bore of wheel hub (10) and profile of tooth flywheel (11) is more bigger than traditional wheel hub, profile of tooth flywheel.One fixing support hollow shaft (12) is arranged between imput shaft (8) and wheel hub (10) and the profile of tooth flywheel (11), support hollow shaft (12) use than hard wear resistant metallic material make.It is stepped near the interior profile of driving gear (9) one sides to support hollow shaft (12), and there is negative thread the termination, can be screwed into and have externally threaded spindle nose (13), the interior ball (14) of having adorned the supporting rolling action supports hollow shaft (12) but outside captive joint gear case (3) or little triangular frame (4).Supporting between hollow shaft (12) outside and the wheel hub (10), and the ball (15) of supporting rolling action has been housed in wheel hub (10) inboard, at this moment, supporting the stepped outside of hollow shaft (12) ball (15) is played the spindle nose effect.In addition, be the outside thread shape in another termination of supporting empty axle (12), can be screwed into tapped spindle nose (16), the ball (18) of supporting rolling action also has been housed between spindle nose (16), support hollow shaft (12) and wheel hub (10), and spindle nose (16) can be captiveed joint with little triangular frame (4).In this same side, imput shaft (8) goes up overcoat bearing (17), and the shell of bearing (17) can be captiveed joint with little triangular frame (4) equally.
During use, support hollow shaft (12) and be connected with little triangular frame (4), imput shaft (8) and wheel hub (10), profile of tooth flywheel (11) can be made non-interfering variable speed and rotate.When imput shaft (8) drives driving gear (9) when rotating, driving gearshaft (19) in driving gear (9) the driven gear case (3), driving gearshaft (19) is coaxial and is the not Equal-diameter gear wheel shaft of T-shape, can play chronotropic action, so driving gearshaft (19) drives profile of tooth flywheel (11) and wheel hub (10) can be made twirl.
Claims (1)
1, a kind of hand-held design concentrical and epitaxial bicycle, mainly by main wheel (1), track adjusting wheel (2), compositions such as little triangular frame (4) and concentric different shaft device, it is characterized in that: described concentric different shaft device is in main wheel (1) wheel hub, internal layer is step imput shaft (8), the middle level is for supporting hollow shaft (12), skin is wheel nave (10) and profile of tooth flywheel (11), wherein support hollow shaft (12) but the little triangular frame of two ends captive joint (4), adopt ball or roller (pin) supporting to separate between three layers of concentric shafts, main wheel (1) diameter is greater than the diameter of track adjusting wheel (2), main wheel (1) support loading, between driving gear (9) and the profile of tooth flywheel (11), be by the not isometrical driving gearshaft of T-shape (19) transmission.
