Abstract
The present invention is a bicycle's shock absorbing and thrust-augmentation mechanism.Belong to technical field of bicycles.The present invention utilizes the advance energy of human body up-and-down movement in the process of bicycle, strengthens the speed of bicycle, and can play cushioning effect.The present invention settles a compression spring between saddle and spider, be in the dynamical equilibrium that relative motion is arranged between human body cushion and the spring, the up-and-down movement of cushion drives two counter-rotational single direction ratchet by rack pinion and commutation conical gear, makes ratchet shaft turn to rotation towards one.Again by linking bond, pull bar, tension spring and chain wheel chain transmission of torque to the flywheel of trailing wheel left side.
Description
The invention belongs to technical field of bicycles.
Known to the contriver:
1: the general only pin of personnel selection of existing bicycle advances as the power driven bicycle.
2: Japan has the people to invent the three-wheel vehicle that a kind of entertainment for children that drives with body weight is used.Drive three-wheel vehicle and advance when cushion descends, cushion plays reset response when rising.
3: the bicycle of using both hands and feet, hand are made garden arc wobble drive front-wheel.
More than select from " science abstract newspaper on June 25th, 86 " " bicycle 85 year first phase of science and technology ".
The present invention can utilize the advance energy of human body vertical tremor in the process of bicycle, strengthens the propelling thrust that bicycle advances, and also plays cushioning effect.The health up-and-down movement acceleration bicycle that makes that also can be artificial advances, thereby makes riding of bicycle more brisk.
The present invention settles a compression spring between cushion that has ordinary bicycle now and spider, in advancing, be in the dynamical equilibrium that relative motion is arranged between human body cushion and the spring, the up-and-down movement of cushion is transferred on the single direction ratchet by rack pinion, and by commutation garden finishing bevel gear cuter Motion Transmission on another single direction ratchet, two single direction ratchet switched in opposite are as long as the cushion up-and-down movement just can rotate towards a direction by axle drive shaft.Axle drives pull bar and tension spring motion by key connecting, and the other end of this spring connects with chain wheel makes chain wheel towards unidirectional rotation, by chain transmission of torque to the flywheel on the bicycle rear left side, the drive trailing wheel advances.When needs are moveed backward, control a shift fork by the upper-lower position of cushion axle is moved with the linking bond position of pull bar, until making chain wheel pull bar and the self-movement of axle energy.
The present invention compared with prior art has following advantage.
1. can utilize the up-and-down movement work done of human body, people's body weight is the speed of advance that a very big power can obviously be accelerated bicycle.
Since in riding human body the pressure of cushion is among the cyclical movement, can utilize this part energy by the present invention, under the situation of the fatigue that does not increase the people, play accelerating action.
3. because ground-surface is uneven, the present invention can utilize the advancing of energy acceleration bicycle of the former body shake that is wasted.
4. can play the vibration damper effect more effectively, bicycle is advanced under the condition of Uneven road quickly.
5. employing the present invention can consider to install solid rubber tyre, thoroughly does away with bicycle and inflates the trouble of gas leakage.
Drawings attached 1 of the present invention and accompanying drawing 2, accompanying drawing 1 is structural representation of the present invention, accompanying drawing 2 is riding position scheme drawing of the present invention.Piece number 1 is a chain wheel among the figure, and piece number 2 is a pull bar, and piece number 3 is a shift fork, and piece number 4 is a linking bond, and piece number 5 is a single direction ratchet, and piece number 6 is an axle.
Claims (3)
1, the present invention makes two single direction ratchet switched in opposite with commutation garden finishing bevel gear cuter, makes the up-and-down movement of cushion all can drive the ratchet shaft unidirectional rotation.
2, the present invention plays buffering and energy reserve with tension spring between chain wheel and pull bar.
3, the present invention considers the function that bicycle retreats, and under the situation that nobody rides, cushion rises to extreme higher position drive shift fork makes the linking bond of ratchet shaft and pull bar lose gearing, and trailing wheel can freely retreat.
