Abstract

The utility model provides a fast bicycle. On the basis of the existing bicycle, a driver which is composed of a rotating shaft, a fixed wheel shaft and four groups of drive gears is added to the footrest of a bicycle frame; besides, the driver is formed in a mode of shaft in shaft; the purposes that oil and electricity are not needed, energy is not consumed, noise and pollution are not generated, and the utility model can drive in a fast or a low speed can be realized through the adjustment of a clutch; the utility model is economical and practical, and the utility model is universal to new bicycles, used bicycles and various models of bicycles.

Description

Quick bicycle

The utility model relates to a kind of bicycle, especially a kind of bicycle of strap drive device.

Bicycle is owing to be that manpower drives, thereby can't reach very high speed, and can fast running in order to make bicycle, big multipurpose oil, the electricity source that is used as power is gone up by society at present, formed with other power and striven the energy, under China's energy-intensive situation, carry out bicycle use oil, electricity consumption is very uneconomical and does not meet national conditions, moreover be power with oil, electricity, make structure become quite complicated, cause the maintenance rate height, cause customer charge to increase, not only expend the energy but also increase user's spending.

The purpose of this utility model provides a kind ofly installs driver one simple in structure, that volume is little on cycle frame is foot-operated, thereby need not expend oil, electric equal energy source, reaches the high-revolving quick bicycle that travels again.

The utility model is to fix a driver of being made up of in axle sleeve axle mode rotating shaft, fixed wheel axle and 4 groups of transmission gears to constitute at the foot-operated place of cycle frame.

Elaborate below in conjunction with accompanying drawing.

Fig. 1 is the utility model surface structure scheme drawing.

Fig. 2 is a driver structural principle scheme drawing of the present utility model.

The utility model keeps each parts of original bicycle constant substantially, fixes a driver Q exactly at the frame pedal place; Driver Q is made up of in axle sleeve axle mode rotating shaft (A), fixed wheel axle (B) and 4 groups of transmission gears; Realize that with 4 groups of gear transmission output speed is greater than the axis rotating speed, and it is identical with turning to of rear axle rotating speed to obtain the axis rotating speed, simultaneously owing to be provided with ratchet H, (12), thereby when power-transfer clutch (3) is worked, the axis rotating speed is separated automatically with output speed, realized travelling at a high speed and the selection of function at a slow speed.

As Fig. 2, (1) for foot-operated, (2) are gear housings, and (3) are power-transfer clutchs, and (4)～(11) are transmission gear, (12) and H be ratchet, (13) are hinge wheel, (14) are chain, (15) are minor sprocket, (16) be hind axle, (17) are trailing wheels, and A is that axis, B are that dead axle, C are rear axles, n ₀Be axis rotating speed, n ₁₁Be output speed, n ₁₇Be rear wheel rotation speed.F among Fig. 1 is the clutch control handle, and E is a linked device.When the power-transfer clutch F with the handlebar place pushes fast shelves, (3) power-transfer clutch of driver Q is just to moving to left, at this moment, (3) with (4) gear mesh, gear (4) meshes with gear (5) thus, gear (5) is connected on the same axis with gear (6) again, so, transmission this moment just is transferred to (7) gear from gear (6), (7) and (8) gear again on same axle, so pass to (9) gear by (8) gear again, (9) gear wheel shaft and H ratchet are fixed on same axle and go up (H plays limit to rotary action), the H ratchet connected with (10) gear and buckle and drive (10) rotation this moment, pass to (11) gear by (10) gear,, be transferred to (15) minor sprocket through chain (14) thereby obtain (11) sprocket wheel because (11) gear wheel shaft is fixed on the same axle with (13) sprocket wheel, when (15) minor sprocket obtains transmission, the effect that realization is travelled with regard to driving the rotation of (17) bicycle rear.Because from n ₀Transmission through the transmitting ratio of 4～11 series of gears groups, obtains n again through (3) clutch transmits rotating speed ₁₁=16n ₀Thereby, obtain n ₁₁＞＞n ₀Run at high speed.In the time will travelling at a slow speed, with (3) disengaging of clutch (to moving to left), n ₀Transmission just directly is delivered to (15) by (12) ratchet drive (13) sprocket wheel, because of without (4-11) serial gear, so $\mathrm{<figure-callout\; id="17"\; label="n"\; filenames="Y9522561600061.png"\; state="\{\{state\}\}">n</figure-callout>}17=\frac{Z_{13}}{{\mathrm{<figure-callout\; id="16"\; label="Z"\; filenames="Y9522561600061.png"\; state="\{\{state\}\}">Z</figure-callout>}}_{16}}\&times;n_0,$ And obtain the normal speed of original common car.Reach at a high speed and the function of travelling at a slow speed selection thereby satisfying is expert at.

The utility model is simple and reasonable for structure, volume is little, in light weight, car load need not done too Many changes need only improve at the frame pedal place of existing car the dress system, not needing can realize oil, Electricity also can reach the purpose of 10～50 kilometers/hour fast running. And noiselessness, do not have dirty Dye, economical and practical, no matter new, used car and each model car all can be general.

Claims (1)

1, a kind of quick bicycle is made up of handlebar, vehicle frame, wheel, seat saddle, foot-operated, bookshelf and support foot.It is characterized in that:

A, fix a driver Q at the frame pedal place;

B, driver Q are made up of in axle sleeve axle mode rotating shaft (A), fixed wheel axle (B) and 4 groups of transmission gears.
