Abstract
The utility model relates to a crankshaft wheel train transmission for a bicycle, which overcomes the laborious defect of present bicycles. The crankshaft wheel train transmission for a bicycle uses a crankshaft and an eccentric shaft, or a pinion gear to replace the centre shaft of a primebicycle for transmission according to the lever principle. The crankshaft wheel train transmission for a bicycle achieves speed changing through a wheel train to cause a chain wheel disk to rotate, and the chain wheel disk drives a flywheel to rotate through a chain. The crankshaft wheel train transmission for a bicycle reduces the frequency for pedaling bicycles by legs and feet to achieve the effects of labor saving, speed increasing, and time saving.
Description
The utility model has been introduced the transmission of a kind of bicycle bent axle train:
China is world's bikedom.At present the bicycle produced of various countries only on the material, on the color, difference to some extent on general structure and the model, also be not resolved from the labour-saving essential technique:
The utility model provides a kind of transmission by the former axis wheel disc of bent axle transmission replacement bicycle, also bent axle can be made eccentric shaft or miniature gears pattern, can be referred to as bent axle.This bent axle transmission is to design according to lever principle, so resistance arm is short more laborsaving more.
The transmission of the utility model bicycle bent axle train has had breakthrough on the essential technique of bicycle labor saving, the frequency when it has reduced people's leg and pedal car has reached laborsaving, speed-raising, the effect in when joint.
This utility model is by left and right sides pedal thigh, bent axle or eccentric shaft, and connecting rod, eccentric gear, variable gear, axle, bearing, casing and small trochal disc are formed.Be installed in former five-way place under the bicycle rack.
The pedal thigh is a power arm about in the time of by bike, and the center of bent axle or eccentric shaft is a fulcrum, and the off-centered distance of bent axle or eccentric shaft is a resistance arm, so power arm is very long, resistance arm is very short, and is no doubt laborsaving.Drive the outer small trochal disc of casing by connecting rod and variable gear and rotate, small trochal disc drives flywheel by chain and reaches speed-raising, slows down.Also can match with double teeth wheel, speed-changing chain, gear shift flywheel.
Fig. 1 is a scheme drawing of the present utility model.
Embodiment of the present utility model is as follows for accompanying drawings:
The transmission of a kind of bicycle bent axle train is pedaled thigh (1) right pedal thigh (2) by left foot and is driven bent axle (3) rotation, by connecting rod (4) eccentric gear (5) multiplying wheel (6) is rotated, by castellated shaft (7) duplex slippage big gear wheel (8) and slippage miniature gears (10) are rotated, when slippage big gear wheel (8) meshes with speed-raising gear (9), make the exterior chain sprocket of casing (13) (14) do the speedup running by axle (12), drive bicycle freewheel by chain again and rotate.Slippage miniature gears this moment (10) is in the jump out of mesh shape with reducing gear (11).When slippage miniature gears (10) meshes with reducing gear (11), make the exterior chain sprocket of casing (13) (14) do reduced power running by axle (12), drive bicycle freewheel by chain again and rotate.Slippage big gear wheel this moment (8) is in the jump out of mesh shape with speed-raising gear (9).Left foot is pedaled thigh (1) right pedal thigh (2) and chain sprocket (14) in casing (13) outside, and other parts are all in osed top casing (13).The very long resistance arm of power arm (15) (16) is very short just laborsaving by bike.Fig. 1 is a bicycle bent axle train drive assembly, and this assembly can be installed in former five-way place under the bicycle rack.
Claims (1)
1, a kind of bicycle bent axle train transmission, it comprises that left foot pedals thigh (1), right pedal thigh (2) and chain sprocket (14); It is characterized in that: be arranged on the exterior left foot of casing (13) and pedal thigh (1) and interior bent axle (3) rotation of right pedal thigh (2) drive casing, drive a pair of gear (5) and rotate with gear (5) gears in mesh (6) by the flat heart of pair of links (4) on the bent axle (3), the castellated shaft (7) of gear (6) makes duplex slippage big gear wheel (8) and slippage miniature gears (10) rotation; When slippage big gear wheel (8) meshed with speed-raising gear (9), the axle (12) of gear (9) made the chain sprocket of fixing on this (14) do the speedup motion, and rotated by chain drive bicycle freewheel; When slippage miniature gears (10) meshed with reducing gear (11), the axle (12) of gear (11) made the chain sprocket of fixing on this (14) do decelerated movement, and drove the bicycle freewheel rotation by chain; This bicycle bent axle train drive assembly is installed in former five-way place under the bicycle rack.
