Abstract
The invention relates to an internally-contained back-stepping type bicycle which has a transmission ratio as a past bicycle and does not need a chain and a fixed large chain wheel device. A middle shaft of the bicycle is contained in a back wheel, and a foot pedal is backward moved beside the back wheel which is sleeved on a big flywheel and a small flywheel of a front shaft and a back shaft. When stepping the foot pedal, a person applies force to a big gear so as to drive a small gear in the same rotating direction, and the small gear acts on the big flywheel which drives the wheels in the same rotating direction. The bicycle has relatively reduced weight and volume and simple structure.
Description
Affiliated technical field
The present invention relates to is a kind of driving type of bicycle, is the once change in the last hundred years to the past bicycle, provides the brand new solution to bicycle.
Background technology
At present, the structure of learning present bicycle by " development history of bicycle " [1] is made up of parts such as vehicle frame, front fork, handlebar, front and back bearings, axis, pedal, flywheel, front and back wheel, big minor sprocket, chain, saddle, front and rear brakes usually.Foot-operated moving hinge wheel by the people drives minor sprocket through chain, acts on the back-wheel drive car by minor sprocket then and advances.But, one, the bicycle of this mode all must drive minor sprocket through chain by hinge wheel, thereby many generations are transmitted the waste of power link through chain.Two, owing to hinge wheel is independently outside, need device of design fix it, therefore increase the reliability of weight, volume and the reduction car of car.[1] bibliography: the development history http://www.123517.com/Article_Print.asp of bicycle? ArticleID=87
Goal of the invention
For weight, the volume that reduces existing bicycle as much as possible, and the reliability that improves bicycle, the invention provides a kind of post legged formula bicycle that includes.The transmitting ratio that not only can as bicycle in the past, have, can also chain and fixedly the device of hinge wheel remove.
The technical scheme that technical solution problem of the present invention is adopted is: in whole vehicle frame, remove chain, remove the fixedly device of hinge wheel.Axis is comprised in the trailing wheel, the foot-operated trailing wheel next door that backward falls back on.1, is parallel to each other with two and passes the inside casing of trailing wheel perpendicular to the axletree of the back vent of bicycle.2, on bottom bracket axle one two identical small flywheels are fixed on the part of same tube, part can independently rotate around axis.3, crank gear is fixed on the end that axis passes back vent.4, big and flywheel that is fixed on rear axle housing.5, miniature gears is fixed on rear axle and passes a back vent and an and crank gear end in the same way.6, the trailing wheel inside casing is enclosed within on a big flywheel and two small flywheels.Foot-operated moving foot-operated when human, masterpiece is used on the big gear wheel, drive with the miniature gears that turns to, miniature gears acts on big flywheel, and big flywheel drives with the wheel that turns to.
The invention has the beneficial effects as follows, can remove the chain of bicycle and the fixing device of hinge wheel, alleviate weight, the volume of car, simple in structure.

The specific embodiment
As shown in Figure 1, in whole vehicle frame, remove chain, remove the fixedly device of hinge wheel, axis is comprised in the trailing wheel, the foot-operated trailing wheel next door that backward falls back on.One, the car body part is made up of front fork (17), front forked assembly (2), handlebar (3), vehicle frame (4), saddle (5).Two, undercarriage promptly is made up of front-wheel (1), trailing wheel (7).Three, running part is made up of foot-operated (15), crank (14), bull gear (12), miniature gears (11), big flywheel (9), axis (13), rear axle (10).Step on foot-operated (15) by manpower, drive wheel revolutions, drive to move ahead by above Transmission.
Be parallel to each other as shown in Figure 2, one, and pass trailing wheel inside casing (4) perpendicular to the axis (9) and the rear axle (6) of the back vent (1) of bicycle with two.Two, put one at axis (9) two identical small flywheels (2) are fixed on the part of same tube, part can independently rotate around axis.Three, crank gear circle (8) is fixed on the end that axis (9) passes back vent (1).Four, put a big flywheel (3) at rear axle (6), and be fixed.Five, miniature gears (7) is fixed on rear axle (6) and passes a back vent (1) and and crank gear circle (a 8) end in the same way.Six, trailing wheel inside casing (2) is enclosed within on a big flywheel (3) and two small flywheels (2).Step on foot-operated (11) by manpower, foot-operated (11) power through crank effect gear ring (8), gear ring (8) drives miniature gears (7), miniature gears (7) directly is used in big flywheel (3) to masterpiece, big flywheel (3) drives trailing wheel inside casing (2) again, and trailing wheel inside casing (2) is used in masterpiece trailing wheel (5) and then drives car and moves ahead.
As shown in Figure 3, the space is passed between axis (1) clump trailing wheel inside casing (2) and the big flywheel (5).The inboard both sides of trailing wheel inside casing (2) is dented.Two small flywheels (4), the dented part slip in the inboard both sides of trailing wheel inside casing (2) respectively.In the middle of the inner bulge part of trailing wheel inside casing (2) groove (3) is arranged.Big flywheel (5), the edge in the middle of a protruding bulge loop (7) is arranged.Big flywheel (5) partly slides in the inner bulge of trailing wheel inside casing (2), and bulge loop (7) is aligning groove (3).Trailing wheel inside casing (2) is to be enclosed within on a big flywheel (5) and two small flywheels (4), and trailing wheel inside casing (2) just can not be subjected to displacement in sum.
Claims (3)
1, a kind of back-stepping type bicycle that includes can drive trailing wheel to manpower according to transmitting ratio bicycle is advanced, and it is characterized in that: without the chain and the fixing device of hinge wheel, axis is comprised in the trailing wheel, the foot-operated trailing wheel next door that backward falls back in whole bicycle.
