Abstract
An arc-shaped rack type bicycle belongs to the field of bicycles and comprises a center shaft, wheel discs and a bicycle frame. The arc-shaped rack type bicycle is characterized in that two sides of the bicycle frame are provided with two long rod pedals which can rotate around a supporting point and are provided with arc-shaped external racks, two ends of the center shaft are respectively sleeved with a unidirectional bearing, a gear is sleeved outside each unidirectional bearing, the gears are meshed with the arc-shaped external racks of the long rod pedals, the two long rod pedals are connected via an interlocking device, and the interlocking device comprises a stay bar, an equal armed lever and two hanging rods. The arc-shaped rack type bicycle can increase driving efficiency of physical strength of the human body, and simultaneously has a variable speed function.
Description
Technical field
The utility model relates to a kind of bicycle.
Background technology
Traditional bicycle all moves in a circle with foot pedal and obtains propulsive effort, and this type of drive has limited the raising of people's physical efficient because there being the problem at acting dead point, be not easy to realize speed changing function simultaneously.
The utility model content
Technical assignment of the present utility model is at the deficiencies in the prior art, and a kind of arc-shaped rack formula bicycle that has higher drive efficiency and possess speed changing function is provided.
The technical solution adopted in the utility model is: arc-shaped rack formula bicycle, comprise axis, wheel disc and vehicle frame, it is characterized in that: two energy are installed in the both sides of vehicle frame around fulcrum shaft stock pedal that rotate, that have tooth bar outside the arc, the axis two ends respectively are with unilateral bearing, the unilateral bearing overcoat gear, gear is meshed with the outer tooth bar of the arc of stock pedal, and two stock pedals connect mutually by linkage, and linkage comprises strut, bascule and two suspension rods.
Compared with prior art the beneficial effects of the utility model are: because the force application apparatus that adopts the stock pedal to step on as the human body pin, both feet alternately are similar to the up-and-down movement of straight line, this has improved people's physical drive efficiency, simultaneously as long as change the function that speed change just can be realized in the double-legged different position, front and back that steps down on the stock pedal.
Description of drawings
Accompanying drawing is the structure principle chart of the utility model most preferred embodiment.
The specific embodiment
Arc-shaped rack formula bicycle as shown in the figure, wherein: 1 bascule, 2,14 suspension rods, 3 struts, the outer tooth bar of 4,13 arcs, 5 wheel discs, 6,7 stock pedals, 8 chains, 9 trailing wheels, 10 axis, 11 unilateral bearings, 12 gears, 15 vehicle frames, 16 fulcrum shafts, unilateral bearing and gear with 11 and 12 corresponding opposite sides among the figure do not draw.
Bicycle with this structure, when pin is stepped on the stock pedal 7 that has tooth bar 13 outside the arc and is moved downward around fulcrum shaft 16, can drive the gear 12 that is engaged with rotates counterclockwise, the unilateral bearing 11 of gear 12 by interior cover drives axis 10 again and rotates counterclockwise, thereby axis 10 drives wheel disc 5 again and rotates and drive trailing wheels 9 by chain 8 and rotate, and is fixed on the linkage that strut 3 on the vehicle frame 15 and bascule 1 and two suspension rods 2,14 form simultaneously and makes stock pedal 6 rise.And when stock pedal 6 moves downward, can repeat same process, trailing wheel 9 can be done the rotation of equidirectional, because the one-way function of unilateral bearing 11 makes that gear 12 dallied when stock pedal 7 rose, can not transmit opposing torques to axis 10.
Claims (2)
