Abstract
The utility model relates to an internally-contained rear-treading gear type bicycle, which has a transmission ratio similar to the transmission ratio of the original bicycle and does not uses a chain and a fixed large sprocket device. Gears are used for the power transmission of the bicycle. A center shaft is contained in a rear wheel. A pedal is backward moved to a position adjacent to the rear wheel. The pedal is treaded by the feet of people. The treading force is applied onto a driving gear through a crank and the center shaft to drive the small gear of a driven gear set. The large gear of the same driven gear set drives an independent gear. The independent gear drives the gear ring of a rear wheel inner frame. The rear wheel inner frame applies the force onto the rear wheel to drive the bicycle to move forward. The utility model can reduce the weight and the volume of the bicycle, and has simple structure.
Description
Affiliated technical field
The present invention relates to is a kind of driving type of bicycle, is the correction to 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 increase the fixedly device of hinge wheel.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.

Summary 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, a driving gear and independent gear on bottom bracket axle.3, independent gear can rotate around axis separately.4, the independent gear while meshes with the big gear wheel of inside casing gear ring and driven tooth wheels.5, big or small driven tooth wheels on rear axle housing; Miniature gears and driving gear engagement.6, two of the trailing wheel inside casing recessed snares are on the small flywheel on the middle rear axle; And a top gear ring is meshed with independent gear.--foot-operated moving foot-operated when human, power is acted on the driving gear through the crank axis, drive the miniature gears of driven tooth wheels, the big gear wheel that goes up on the same group drives independent gear, and the gear ring of independent gear driven trailing wheel inside casing reaches and drives the purpose that car advances.
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 (16), 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 (14), crank (13), driving gear (10), driven tooth wheels (9), axis (13), rear axle (10), independent gear, gear ring.--step on foot-operatedly 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 (5) perpendicular to the axis (10) and the rear axle (9) of the back vent (1) of bicycle with two.Two, put a driving gear (8) and independent gear (2) at axis (10).Three, independent gear (2) can rotate around axis (10) separately.Four, independent gear (2) while meshes with the big gear wheel (7) of inside casing gear ring (4) and driven tooth wheels.Five, big or small driven tooth wheels (7) on rear axle housing; Miniature gears (7) and driving gear (8) engagement.Six, one side of trailing wheel inside casing (5) have gear ring (4) and with independent gear mutually (7) engagement.--by human foot-operated moving foot-operated (12), power is acted on the driving gear (8) through crank (11) and axis (10), drive the miniature gears (7) of driven tooth wheels, the big gear wheel that goes up on the same group (7) drives independent gear (2), independent gear (2) drives the gear ring (4) of trailing wheel inside casing, and trailing wheel inside casing (5) is used in masterpiece trailing wheel (6) and then drives car and moves ahead.
As shown in Figure 3, axis (9) and rear axle (7) with trailing wheel inside casing (3) one side put two small flywheels (5) respectively.Small flywheel (5) axially be fixed on axle axially on.Small flywheel (5) can be freely around the radially rotation of axle.Two recessed snares of trailing wheel inside casing (3) are on the small flywheel on the middle rear axle.Trailing wheel just can axially can not walked about like this, and can freely rotate diametrically.
Claims (3)
1. step on the gear type bicycle after including for one kind, can drive trailing wheel to manpower according to transmitting ratio bicycle is advanced, it is characterized in that: at whole bicycle use gear transmission, axis is comprised in the trailing wheel, the foot-operated trailing wheel next door that backward falls back on.
