Description

A kind of pedal rotates forward the Chainless type Exercycle that reversion can move ahead

Technical field

The utility model is related to a kind of pedal and rotates forward the Chainless type Exercycle that reversion can move ahead, and belongs to body building self running Car technical field.

Background technology

Bicycle was conventional industries, with the history of more than 100 years, the problem of due to environmental protection and traffic, and bicycle is once again As the countries in the world traffic that particularly developed country resident likes, while the attention with people to body, bicycle also into For popular motion, body-building, leisure and recreational product.Japanese CYCLEPRESS data statistics shows, the annual whole world Bicycle demand is huge, and whole world bicycle demand size is maintained at the level of 1.06 hundred million, and bicycle annual volume is about 5000000000 dollars.

Existing bicycle maintains earliest design principle substantially under this production scale, and preceding pedal can walk, the mould Formula can be very good as the vehicles, but as body-building for, pedal walking mode before it excessively single, it is impossible to meet existing inverse To the demand of body building, meanwhile, existing bicycle is generally chain driving, and chain is easy to chain when in use, to making User makes troubles, i.e.,：A kind of pedal is needed to rotate forward the Chainless type Exercycle that reversion can move ahead.

The content of the invention

The technical problems to be solved in the utility model is to provide a kind of pedal and rotates forward the Chainless type body-building that reversion can move ahead Bicycle, can overcome the deficiencies in the prior art.

The technical solution of the utility model is：A kind of pedal rotates forward the Chainless type Exercycle that reversion can move ahead, it Including vehicle frame, wheel and pedal connecting shaft are connected with vehicle frame, pedal parts are connected with pedal connecting shaft, on vehicle frame Worm gear connecting shaft is connected with, gear-box, the pedal in gear-box are provided with the pedal connecting shaft and worm gear connecting shaft of vehicle frame A drive gear and No. two drive gears are socketed with connecting shaft, is installed in worm gear connecting shaft one end provided with preceding worm gear, reversely The first flywheel and the second flywheel, a driven gear is connected with the first flywheel, be connected with the second flywheel No. two from Moving gear, a drive gear and a driven gear engagement, are provided between No. two drive gears and No. two driven gears and mutually nibble The idler gear of conjunction, preceding worm gear is connected by worm screw with rear worm wheel, and rear worm wheel is connected with the 3rd flywheel on hind axle.

The 3rd above-mentioned flywheel includes the axle sleeve being connected on axletree of rear wheel, ratchet is hinged with axle sleeve, on ratchet Matched ratchet when being rotated forward provided with wheel, when wheel is reversed, ratchet retraction does not coordinate with ratchet.

Spring is provided between above-mentioned axle sleeve and the ratchet being hinged, the elastic force of spring is more than the maximum gravity of ratchet, is less than The gravity of ratchet adds centrifugal force.

No. two drive gears, idler gear, No. two driven gears are equipped with more than one big ting model.

It is above-mentioned in gear-box provided with dividing plate by a drive gear, a driven gear and No. two drive gears, in Between gear, No. two driven gears be spaced, outer wall and middle level dividing plate are provided with the gear shaft of idler gear.

Above-mentioned worm screw is made up of front and rear two-section bar, and universal joint is provided with intermediate connections.

Prior art compares, and the utility model is connected with worm gear connecting shaft on vehicle frame, vehicle frame pedal connecting shaft and Worm gear connecting shaft is provided with gear-box, the pedal connecting shaft in gear-box and is socketed with a drive gear and No. two sliding tooths Wheel, in worm gear connecting shaft one end provided with preceding worm gear, the first flywheel and the second flywheel reversely installed, is connected with the first flywheel A number driven gear, is connected with No. two driven gears, a drive gear and a driven gear engagement, two on the second flywheel Provided with the idler gear being meshed number between drive gear and No. two driven gears,

When pedal connecting shaft is rotated forward, No. two drive gears are meshed by idler gear with No. two driven gears, Worm gear wheel before No. two driven gears synchronously drive, preceding worm gear drives rear worm wheel to rotate by worm screw, so as to drive rear car The rotation of wheel, now under the influence of the first flywheel reversely installed, a drive gear and a driven gear intermeshing Idle running, realizes that positive pedal bicycle moves forward.When foot-operated reversion, No. two driven gears are influenceed not drive by the second flywheel Dynamic worm gear connecting shaft, and the drive gear reversely rotated can then drive a driven gear of engagement forward rotation synchronization belt Worm gear wheel before dynamic, preceding worm gear drives rear worm wheel to rotate by worm screw, so as to drive the rotation of rear wheel, realizes reverse pin Pedal since Chinese herbaceous peony row；Body-building so can be preferably realized, and permanent cycling personnel can effectively be loosened；

Preceding worm gear is connected by worm screw with rear worm wheel, and rear worm wheel is connected with the 3rd flywheel on hind axle, can so be solved The problem of bicycle often falls chain during linked transmission；

3rd flywheel includes the axle sleeve being connected on axletree of rear wheel, and ratchet is hinged with axle sleeve, and car is provided with ratchet Wheel ratchet matched when rotating forward, when wheel is reversed, ratchet retraction does not coordinate with ratchet, between axle sleeve and the ratchet being hinged Provided with spring, the elastic force of spring is more than the maximum gravity of ratchet, and the gravity less than ratchet adds centrifugal force, such 3rd flywheel Design may insure bicycle when retroversion is push, and the gear on the 3rd flywheel will not be rotated, so as to have influence on worm gear company The cooperation of each part in spindle.

No. two drive gears, idler gear, No. two driven gears are equipped with more than one big ting model, this can according to Size is arranged in pairs or groups between the different height in family and use habit carry out these three gears, such as No. two drive gears, idler gear, No. two driven gears become big successively by small, so as to reach labour-saving effect；

It is above-mentioned in gear-box provided with dividing plate by a drive gear, a driven gear and No. two drive gears, in Between gear, No. two driven gears be spaced, outer wall and middle level dividing plate are provided with the gear shaft of idler gear, are so avoided that gear Interfered with each other during rotation；

Above-mentioned worm screw is made up of front and rear two-section bar, and universal joint is provided with intermediate connections, can so be realized between rotating shaft Varied angle transmits power, can effectively protect product；

Design structure of the present utility model is pedaled when going up a slope or walking at a high speed before suggestion simultaneously, after level road suggestion selection Pedal.
