Abstract

The invention provides a bicycle composed of racks, double ratchet wheels and double semi-gears. When a downward movement is generated by a cushion 1, the right rack 4, a left pedal 3 and a right pedal 4 are driven by a swing gear 5 to generate upward movements at the same time; and power is transmitted to a shaft of the ratchet wheel 6 in the clockwise rotation process of the ratchet wheel 6 on the lower left rack 11 and then the power is transmitted to a flower disc gear through four linkage gears. When the left pedal 3 and the right pedal 4 are treaded at the same time, the left rack and the cushion are driven by the swing gear 5 to generate the upward movement and the power is transmitted to the flower disc gear through the shaft of the ratchet wheel 9 in the anticlockwise rotation process of the ratchet wheel 9 on the lower left rack. Therefore, the downward movements of the cushion and the left and right pedals act and are respectively transmitted to the driving bicycle through the ratchet wheel 6 and the ratchet wheel 9; meanwhile, the driving kinetic energy drives the cushion and the left and right pedals to generate up and down movements through the two semi-gears.

Description

The bicycle of swerving the weight

Technical field:

The present invention relates to by cushion up and down with two stretchers the time back and forth drive two ratchets actings through tooth bar up and down, the power of bicycle running also can move up and down through two and half gear drive stretchers or cushion conversely simultaneously.

Technical background:

Present bicycle is that the single direction ratchet transmission makes chain can't drive pedal generation motion because of the trailing wheel employing.

Summary of the invention:

The driving device of a kind of novel structure that the objective of the invention is to fill up the blank of this area and provide.

The objective of the invention is to move downward when the power that goes produces cushion or stretcher respectively through half gear; We can be the gravity-center-change of human body to cushion when cushion moves downward; When stretcher moves downward we again gravity-center-change to both feet, in the moving downward respectively of cushion or double-legged pedal, just can utilize gravitational potential to produce acting like this.In existing bicycle drive technology, still do not have the driving device of this kind structure, the blank of bicycle transmission field can be filled up by this kind mechanism.

The object of the invention can reach through following measure: a kind of bicycle; Comprise cushion, left and right sides pedal, upper left tooth bar, right tooth bar, a left side is tooth bar, escapement, four connection gear, floral disc, chain, rear axle gear, trailing wheel, two ratchets, two and half gears down.

Description of drawings:

Fig. 1 is a structural representation of the present invention.

Attaching piece number representes:

Cushion 1, upper left tooth bar 2, left foot pedal 3, right steps 4, pendulum gear 5, ratchet 6, half gears 7, half gears 8, ratchet 9, right tooth bar 10, upper left tooth bar 11, chain 12, floral disc gear 13, rear axle gear 14, trailing wheel 15, transmission gear 16.

The specific embodiment:

To combine accompanying drawing that the present invention is done further ocean below states:

Fig. 1 is an overall structure of the present invention.When the tooth bar under the cushion is depressed by self gravitation; Left tooth bar upper end, lower end ingear is put gear 5 and will be driven and right tooth bar of its ingear and left and right sides pedal generation upstroke, and the ratchet 6 on the tooth bar of left lower end will be delivered to power on the tooth of floral disc through four connection gear in doing the clws rotation simultaneously.Pendulum gear 5 will drive left tooth bar and cushion generation upstroke when left and right sides pedal is stepped on simultaneously; At this moment a left side down the ratchet 9 on the tooth bar will in rotating counterclockwise, be delivered to power on the floral disc tooth through its axle, like this cushion move downward or moving downward of left and right sides foot pedal passed through floral disc, chain, rear axle tooth to power to trailing wheel all clearly in the crank motion of tooth bar.

Claims

1. the two ratchet bicycles of tooth bar comprise left-hand tread plate (1), pendulum gear (2), upper left tooth bar (3), right tooth bar (4); Ratchet (5), right-hand tread plate (6), a left side is tooth bar (7) down, ratchet (8), connection gear (9); Floral disc (10), chain (11), rear axle ratchet (12), trailing wheel (13).

2. the two ratchet bicycles of tooth bar according to claim 1 is characterized in that meshing simultaneously on the tooth bar ratchet 5, ratchet 8, and upper left tooth bar 3 meshes with right tooth bar 4 with pendulum gear 2 simultaneously.

3. the two ratchet bicycles of tooth bar according to claim 1; The descending cw by ratchet 5 that it is characterized in that tooth bar makes transmission of power to its axle and floral disc; Tooth bar up by rotating counterclockwise of ratchet 8 make transmission of power behind its axle again through four connection gear to floral disc, the remain unchanged circumference of direction of four connection gear rotates.
