Abstract

The invention discloses a bike which mainly comprises a longitudinal frame 3. A front handlebar 1 is mounted at the front end of the frame 3 through a bearing and mounted with a front wheel 2, the front handlebar and the front wheel can freely steer horizontally, pedals 4 are fixed on the frame 3, a gear 5 is mounted at the rear end of the frame 3 and mounted on a bearing support 10 through a bearing 6, a left half axle 12 and a right half axle 8 are mounted at the left end and the right end of the bearing support 10 through bearings respectively, a gear 11 of a ratchet mechanism is mounted at the inner end of the left half axle 12 and meshed with the gear 5, and a wheel 13 is mounted at the outer end of the left half axle 12. A gear 7 of the ratchet mechanism is mounted at the inner end of the right half axle 8 and meshed with the gear 5, a wheel 9 is mounted at the outer end of the right half axle 8, and a flywheel or an overrunning clutch is mounted at the center of each of the wheel 9 and the wheel 13 to guarantee the wheels to be capable of freely rotating forward without receiving driving force from the axles. A person riding the bike treads the pedals 4 with the help of own gravity during riding.

Description

A kind of bicycle

Technical field

The present invention is a kind of bicycle, relates to one and allows user rely on gravity, to trample pin in the mode of standing up and down The vehicle that pedal-driven car body moves ahead, it relies primarily on human body self gravitation and originates as driving force.

Background technology

The most conventional standard bicycle includes that perambulator is all to be driven cycle wheel to advance or straight by user's foot chain wheel Connect driving pedal wheel to advance.Bicycle with its simplicity, environmental protection, low cost practicality by extensive favorable comment and use.By chain wheel drive, The drive mechanism both feet to be leaned on of chain drive are trampled pedal and are circled, and this motion needs bicyclist's maximum to use leg Strength, human body self gravitation can not make full use of, and human posture is flexible non-stand-up, of long duration preferably produces physical fatigue, right Health is correctly grown with impact.The bicycle directly driving pedal wheel to advance mostly is ridden for children.Slide plate class need use One the feet step on the ground obtains mover runner, can not run the most again distance.The existing bicycle pedal driven by self gravitation Running orbit is all around solid fixed-axis rotation or to do reciprocating, or installing accessory makes human body self gravitation energy on former bicycle Work as driving force, but its simple in construction limited use.

Summary of the invention

The present invention is to be trampled pedal based on bicyclist by himself Action of Gravity Field both feet, and pedal sticks up around fixing axle The innovation that board-like reciprocating moves ahead to drive bicycle.

The present invention adopts the following technical scheme that

1, the present invention is a kind of bicycle, mainly includes longitudinal vehicle frame 3, and front truck is installed 1 by bearing in vehicle frame 3 front end, handlebar 1 Being provided with front vehicle wheel 2, front truck is installed wheel can be freely horizontally diverted because of bearing.Pedal 4 it is fixed with, after vehicle frame 3 on vehicle frame 3 Hold equipped with gear 5 and be arranged on the support of bearing 10 by bearing 6.On the support of bearing 10, bearing is passed through at two ends, left and right respectively Left half axle 12 and right axle shaft 8 are installed.Left half axle 12 the inner is provided with gear 11 meshing gear 5 of ratchet mechanism, and car is installed in outer end Wheel 13.Right axle shaft 8 the inner is provided with gear 7 meshing gear 5 of ratchet mechanism, outer end installing wheel 9.In wheel 9 and wheel 13 Ratchet wheel or freewheel clutch are installed at the heart, it is ensured that axle wheel when not giving driving force can rotate the most forward.

The effect of the present invention:

1, human body self gravitation direct drive of wheel efficiency height is fixed on longitudinal direction vehicle frame 3 because of pedal, and vehicle frame 3 is installed gear 5 direct engagement two-semiaxle gears 7 and 11, the direct tire on the drive wheels of the driving force lossless efficiency that moves ahead is high.

2, type of drive is novel

Bicyclist only need both feet trample moving seesaw-type pedal make up-and-down reciprocating motion vehicle can be driven to advance.

3, simple in construction, volume is little, and lightweight being easily installed is carried

Vehicle overall structure is simple, and without lengthy and tedious odd parts, small in volume is easily installed carries.

4, can applied range

Because its type of drive is novel, can be applicable to adult bicycle, adult's exercise vehicle and children riding bicycle range of application Extensively.

Accompanying drawing illustrates:

Fig. 1 is bicycle overall structure schematic diagram.

Fig. 2 is equipped with the wheel of the ratchet of single effect.

Detailed description of the invention:

Need only design as required and front truck is installed by bearing in vehicle frame 3 front end in Fig. 1 make the front truck can Free water 11 Flat turn to.Vehicle frame 3 rear end is provided with ratchet in installing gear 5 meshing gear 7 respectively and gear 11. gear 7 and gear 11 and can make Semiaxis 8 and the unidirectional freedom of semiaxis 12 rotate forward.Semiaxis 8 and semiaxis 12 and vehicle frame 3 are arranged on the support of bearing 1 by bearing respectively On 0.Wheel 9 is arranged on semiaxis 8 equipped with non-return device ratchet or freewheel clutch, and wheel 13 is equipped with non-return device ratchet or super More clutch is arranged on semiaxis 12, it is ensured that wheel 9 and 13 is unidirectional rotatable in a free state.Bicyclist only needs both feet to trample Pedal just can drive wheel 9 and 13 to rotate respectively and make vehicle forward.

Claims

1. a bicycle, mainly includes longitudinal vehicle frame 3, and front truck is installed 1 by bearing in vehicle frame 3 front end, before handlebar 1 is provided with Wheel 2, front truck can freely be horizontally diverted wheel, and vehicle frame 3 is fixed with pedal 4, and vehicle frame 3 rear end equipped with gear 5 and leads to Crossing bearing 6 to be arranged on the support of bearing 10, on the support of bearing 10, left half axle 12 and right half are installed by bearing respectively in two ends, left and right Axle 8, left half axle 12 the inner equipped with gear 11 meshing gear 5 of ratchet mechanism, outer end installing wheel 13, right axle shaft 8 the inner equipped with Gear 7 meshing gear 5 of ratchet mechanism, outer end installing wheel 9, wheel 9 and wheel 13 center are installed can the spine of single effect Wheel or freewheel clutch, it is ensured that axle wheel when not giving driving force can rotate the most forward.
