The power input wheel 1 is connected with the small-diameter gear A of the transmission wheel component 2 through chains. The big-diameter gear B of the transmission wheel component 2 is connected with the output wheel through chains. The power input wheel 1 is fixedly connected with the power input shaft 4. The gear A of the middle transmission wheel component 2 is rolling connected with the power output shaft 5. The gear B of the middle transmission wheel component 2 is glidingly connected with the power input shaft 4. The power output wheel 3 is fixedly connected with the power output shaft 5.
Description
One, technical field:
The utility model is a kind of gear transmission, belongs to gear change machinery field.
Two, background technology:
Because the expansion in city now, selection trend variation to city traffic, it is very inconvenient that the way of a kind of mode of transportation of single use in the past becomes, thus be used alternatingly the selection that the multiple vehicle become quite a few people, and folding bicycle has solved this problem just.Existing folding bicycle makes the car load design size be subjected to considerable restraint, particularly the size of wheel owing to easy to carry.Wheel is excessive will to carry inconvenience, and the too small running velocity that can influence folding bicycle of wheel.At first the human body maximum speed of revolution that scrunches bicycle pedal has determined the bicycle gears transmission to drive the maximum speed of trailing wheel rotation.So because the moving velocity of the very little folding bicycle of wheel of folding bicycle has been subjected to very big influence, it is limited only to rely on the acceleration effect of 1 change-gear set still to improve the speed of a motor vehicle.When wheel revolutions speed surpassed human body and scrunches the maximum speed of revolution of bicycle pedal, skidding and dallying will appear in vehicle, and car body vibrations take place loses the vehicle balance easily and causes traffic accident.Application number is 200410039597.7 to disclose a kind of portable station wagon, and its change gear transmission part reaches the effect that 2 grades of speed changes improve Vehicle Speed by increase a variable gear between power input wheel and power output wheel.Such improvement has improved the maximum speed of folding bicycle wheel to a certain extent, but change wheel that increases simultaneously and change wheel pivot shaft make folding change very difficult of car body, has increased the volume of folding aftercarriage, makes and carries inconvenience.And to exercise the increase of maximum speed still be limited to improving vehicle only to increase a change wheel, increase variable gear in this way and also will increase more speed change intermediate gear pivot shaft, the vehicle volume certainly will to be increased, so this kind gear shift mode has been subjected to considerable restraint in actual production.
Three, summary of the invention:
The utility model is achieved through the following technical solutions.
A kind of optimal technical scheme of the present utility model is a kind of driving gear set, comprise power input wheel 1, one group of above intermediate drive wheel assembly 2, a power output wheel 3, power input shaft 4, power take-off shaft 5, power input wheel 1 is connected by chain with the A wheel small diameter gear of driving pulley assembly 2, the gear wheel in large diameter of driving pulley assembly 2B wheel is connected by chain with output wheel, described power input wheel 1 is captiveed joint with power input shaft 4, the A wheel of intermediate drive wheel assembly 2 rolls with power take-off shaft 5 and is connected, the B wheel and power input shaft 4 sliding block joints of described intermediate drive wheel assembly 2, and power output wheel 3 is captiveed joint with power take-off shaft 5.
It is of the present utility model that more to advance a kind of optimal technical scheme be that described intermediate drive wheels 2 comprise two identical geared parts A and B, described geared parts is that the gear wheel in large diameter of the A wheel of described intermediate drive wheels 2 and the small diameter gear of B wheel are rotationally connected by chain by a gear wheel in large diameter and fixing coaxial the connecting and composing of small diameter gear.
The A wheel that another optimal technical scheme of the present utility model is described intermediate drive wheel assembly 2 is supported on the power take-off shaft 5 by bearing element, the B wheel is supported on the power input shaft 4 by bearing element, described power input wheel 1 is a crank and chain-wheel, comprises coaxial being fixedly connected on the power input shaft of variable gear riveted joint that a slice is above.
Also a kind of optimal technical scheme of the present utility model is that power input wheel 1 is connected by chain with the A wheel small diameter gear of intermediate drive gear group 2, power output wheel 3 is connected by chain with the B wheel gear wheel in large diameter of intermediate drive gear group 2, is provided with the inhibiting device that limiting gear horizontally slips on power input shaft 4 and power take-off shaft 5.
Most preferred technique scheme of the present utility model is that intermediate drive wheel assembly 2 can be installed more than one group, and described driving gear set can be used on other variable transmission mechanisms.
By above technological improvement, multi-stage speed-changing structure is simplified, dwindle its occupation of land volume and reached the folding effect of convenience.
Four, invention effect:
The utility model is by increasing the transmitting ratio that driving pulley assembly more than one group improves folding bicycle chain gear parts, and the variable gear that is increased does not need new pivot shaft, only relies on power input shaft and power take-off shaft to do support.More obvious than existing speed change difference or the 2 grades of speed changing effect lifting effects that increase a midship mounting axle of a variable gear that rely on moving wheel for inputting and power output wheel to produce, and vehicle integral body is compact more.
Five, Figure of description:
1, Fig. 1 is the constructional drawing of this gear transmission;
1 is that power input wheel, 2 is that intermediate drive wheel assembly, 3 is that power output wheel, 4 is that power input shaft, 5 is power take-off shaft.
2, Fig. 2 is the block diagram of 2A or 2B in the intermediate drive wheel assembly;
Six, embodiment:
The 2A gear of change gear transmission assembly is supported on the power take-off shaft by bearing element, and the 2B gear of change gear transmission assembly is supported on the power input shaft by bearing element.Reach mechanism's compactness by folding layout design, and improved a speed change grade.
This kind change gear transmission group can be provided with a plurality of, is installed on power input shaft and the power take-off shaft by bearing element, makes this mechanism can make the revolution ratio with power input shaft and power take-off shaft reach quite high effect through multi-change speed.Be applicable to various hoisting device simultaneously or by the high knob distance of motor-operated needs, slow-revving mode of operation.
