Abstract
The utility model discloses a linear rack gear driving labor saving bicycle. Both ends of a middle shaft are respectively provided with a one-way driving ratchet wheel mechanism on which a gear wheel is arranged. A bicycle body is also provided with a linear gear rack support frame in which two linear gear racks and pulley wheels are arranged. The linear gear racks and the gear wheels are engaged. A flexible rope passes through the pulley wheels, and both ends of the flexible rope are respectively connected with the two linear gear racks on which a pedal is respectively arranged. When the utility model is used, pedal power can generate a force moment which is kept in a maximum state all the time for chain wheels, and the function of man power can be fully exerted. In addition, the utility model has the advantages of simple structure, easy fabrication, and low cost.
Description
The utility model relates to a kind of bicycle.
At present, bicycle of the prior art generally all is to step on after driving sprocket rotation on the pedal crank of bicycle by the people, drive wheel by chain and flywheel again, when the people when riding this bicycle, the rotation that the direction of its foot-operated power turns along with bicycle pedals and continuous variation takes place, thereby foot-operated power also changes constantly to the moment size that sprocket wheel produced, when the direction of foot-operated power turns into an angle of 90 degrees when spending with stepping on, its moment maximum, and other the time, under identical foot-operated power situation, but can not get maximum moment, thereby can not bring into play the manpower effect well, waste many manpowers in vain.
The purpose of this utility model is: provide a kind of linear pattern rack driven labour-saving bicycle that can give full play to the manpower effect, to overcome the deficiency of existing bicycle.
The utility model is to constitute like this: it comprises and has wheel, the car body of seat cushion and handlebar (1), bicycle freewheel (2), driving chain (3), axis (4), sprocket wheel (5), flywheel (2) is contained on the hind axle of car body (1), axis (4) is contained on the car body (1), sprocket wheel (5) is contained on the axis (4), driving chain (3) is enclosed within on flywheel (2) and the sprocket wheel (5), the ratchet device (6) of a unidirectional transmission also is housed respectively at the two ends of axis (4), gear (7) is housed on ratchet device (6), linear pattern tooth bar support (8) also is housed on car body (1), two linear pattern tooth bars (9) and pulley (10) are housed in support (8), linear pattern tooth bar (9) and gear (7) engagement, tightrope (11) is connected on two linear pattern tooth bars (9) by its two ends, pulley (10) back, and stretcher (12) is housed on linear pattern tooth bar (9); Side leading sheave (13) and bottom surface leading sheave (14) also can be housed on linear pattern tooth bar (9).
Owing to adopted technique scheme, the utility model compared with prior art has the advantage that can give full play to the manpower effect.During use, the people is sitting in this and uses on the later-model seat cushion, step stretcher (12) respectively downwards with both feet, at this moment a linear pattern tooth bar (9) that moves downward drives with its gears in mesh (7) and rotates, gear (7) drives axis (4) by ratchet device (6) and rotates, thereby also just driving sprocket wheel (5) rotates, sprocket wheel (5) drives wheel by driving chain (3) and flywheel (2), and another root linear pattern tooth bar (9) is because the effect upward movement of tightrope (11), rotate in the opposite direction thereby drive with another gear of its ingear (7), because ratchet device (6) can only be made folk prescription to transmission, thereby when gear (7) when making counter-rotation, gear (7) can not pass through ratchet device (6) and drive axis (4) rotation, because people's foot-operated power is to step to the chute downward direction along support (8) all the time, can change of direction, its foot-operated power remains at maximum optimum regime to moment that sprocket wheel produces, thereby has brought into play the manpower effect fully.In addition, the utility model also has advantage simple in structure, that making is easy, with low cost.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is a linear pattern rack and pinion engaging structure scheme drawing of the present utility model;
Accompanying drawing 3 is a support mounting structure scheme drawing of the present utility model.
Embodiment of the present utility model: have wheel, the car body of seat cushion and handlebar (1), bicycle freewheel (2), driving chain (3), axis (4), the making of sprocket wheel (5) can adopt method for making of the prior art to make, and according to a conventional method flywheel (2) is contained on the hind axle of car body (1), axis (4) is contained on the car body (1), when axis is installed, its position is higher than the middle shaft position of conventional bicycle, sprocket wheel (5) is contained on the axis (4), driving chain (3) is enclosed within on flywheel (2) and the sprocket wheel (5), adorn the ratchet device (6) of a unidirectional transmission during installation more respectively at the two ends of axis (4), ratchet device (6) can adopt the conventional ratchet device of selling on the market, on two ratchet devices (6), load onto a gear (7) respectively, go up an installation linear pattern tooth bar support (8) at car body (1), in support (8), load onto two linear pattern tooth bars (9) and two pulleys (10), linear pattern tooth bar (9) is meshed with a gear (7) respectively, tightrope (11) is connected on two linear pattern tooth bars (9) by its two ends, pulley (10) back, on linear pattern tooth bar (9), adorns a stretcher (12) respectively; For the power of reducing friction, adorn two side leading sheaves (13) in the side of linear pattern tooth bar (9) respectively and on its bottom surface, adorn 6 bottom surface leading sheaves (14) respectively and get final product.
Claims (2)
1, a kind of linear pattern rack driven labour-saving bicycle, it comprises and has wheel, the vehicle body of seat cushion and handlebar (1), bicycle freewheel (2), driving chain (3), axis (4), sprocket wheel (5), flywheel (2) is contained on the hind axle of car body (1), axis (4) is contained on the car body (1), sprocket wheel (5) is contained on the axis (4), driving chain (3) is enclosed within on flywheel (2) and the sprocket wheel (5), it is characterized in that: the ratchet device (6) that a unidirectional transmission also is housed respectively at the two ends of axis (4), gear (7) is housed on ratchet device (6), linear pattern tooth bar support (8) also is housed on car body (1), two linear pattern tooth bars (9) and pulley (10) are housed in support (8), linear pattern tooth bar (9) and gear (7) engagement, tightrope (11) is connected on two linear pattern tooth bars (9) by its two ends, pulley (10) back, and stretcher (12) is housed on linear pattern tooth bar (9).
