Abstract
The utility model discloses a bicycle with gearing-up shaft and double pedals. The bicycle with gearing-up shaft and double pedals is characterized in that a pair of gearing-up shafts [4], [4'] are arranged adjacent to the lower part on both sides of a rear axle shaft; the gearing-up shafts act as the fulcra of lever torque, and a pair of crossed rod type pedal plates (double pedals [1], [1'] for short) are arranged on the gearing-up shafts. Crank connecting rods [2], [2'] and a differential gear shaft [3] can realize the to and fro swivel motions of the double pedals from top to bottom. The bicycle with gearing-up shaft and double pedals can thoroughly change the forcing manner of circumferential motions by both feet at present, and accordingly, 1/2 idle labor of the circumferential motions by both feet can be reduced. The bicycle with gearing-up shaft and double pedals is fast for riding and labor saving.
Description
The utility model relates to a bicycle driving device, and the actuating device of two pedal gear increaser axle particularly is housed on the bicycle.
Existing all kinds bicycle driving device is with foot-operated pedal, rotates hinge wheel, through the chain transmission, comes drive rear wheels to rotate with the mode that both feet are turn-taked, and makes car body to overtake.
The weak point of this conventional drive mode:
1. double-legged tap pedal one in front and one in back is mutually the straight angle, has only 1/2 garden Zhou Yundong to rotate hinge wheel, promotes car body and does work to overtake, and remaining garden Zhou Yundong overcomes friction drag and lift the rear foot to have done idle work.
When pedal when axis turns round, the restriction of wheelbase floor level during its length is subjected to can't make pedal (power arm) increase, to pedal can not be laborsaving.
The utility model will provide a kind of improved bicycle that two pedal gear increaser axle is housed for solving the weak point of present double-legged garden Zhou Yundong force method.It can reach laborsaving to pedal fireballing effect.
The utility model is achieved in that
In down either side, respectively load onto a pair of gear increaser axle (4), (4 ') near back axle.Respectively load onto a crossbar type stretcher (being called for short two pedal (1), (1 ')) at this axle.Can make two pedal do motion up and down by crank connecting link (2), (2 ') and differential gear axle (3) rotates back axle (5) and makes car body to overtake.
The bicycle of this utility model has been broken through traditional type of drive.It adopts two pedal gear increaser shaft drive, and not only novel structure, and transmission device all is in sealing state, prevents that foul from entering, and prolonged service life of gear.Through implementing checking, all easily laborsaving and speed is fast in the time of in climbing or against the wind.
Concrete structure of the present utility model is illustrated by the following drawings.
Fig. 1 is the bicycle driving set-up diagram that two pedal gear increaser axle is housed that the utility model proposes.
This device mainly by two pedal (1), (1 '), crank connecting link (2), (2 '), differential gear axle (3), gear increaser axle (4), (4 '), hind axle (5), form.
Fig. 2 is the birds-eye view of actuating device.
Fig. 3 is the assembling section of differential gear axle (3).
Differential gear axle (3) is the garden finishing bevel gear cuter Z that intersects vertically by two couples

Embodiment of the present utility model is as shown in drawings:
Differential gear axle (3) is installed in position at the ordinary bicycle axis.The differential gear axle is the garden finishing bevel gear cuter Z that intersects vertically by two couples as shown in Figure 3
