Abstract

The utility model belongs to a walking assistant tool, and particularly relates to a double-wheel balance pedal stick torque changing type bicycle laborsaving apparatus. The apparatus provided includes a chain (7), pedals (5), a pedal stick 1 (4), a pedal stick 2 (8), a middle shaft (3), and a large sprocket wheel disc (6), the right end of the middle shaft (3) is provided with the large sprocket wheel disc (6), the outer side of the large sprocket wheel disc (6) is fixedly provided with the pedal stick 1 (4), one pedal (5) is arranged on the pedal stick 1 (4), the left end of the middle shaft (3) is movably provided with a balance wheel disc (2), the outer side of the balance wheel disc (2) is fixedly provided with the pedal stick 2 (8) which is in 180-degree symmetry with the pedal stick 1 (4), and the other pedal (5) is arranged on the pedal stick 2 (8). The double-wheel balance pedal stick torque changing type bicycle laborsaving apparatus provided is simple in structure and laborsaving in riding, and is particularly suitable for riding in a long distance and riding on an uneven road surface and an uphill road surface.

Description

The two-wheel balanced pedaling turns moment varying type bicycle power-saving devices

Technical field

The utility model belongs to walking-replacing tool, and particularly a kind of two-wheel balanced pedaling turns moment varying type bicycle power-saving devices.

Background technology

At present, all there is the shortcoming of the effort of riding in existing bicycle, particularly long-distance, ride or meet scraggly road and while going up a slope, require great effort especially, battery-driven car is with its quick, laborsaving favor that is subject to people, but exist, needs often charging, not only bothersome but also waste electric shortcoming, and also more expensive than price with bicycle, use also inconvenient.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, and the two-wheel balanced pedaling of being convenient to way far away, He Po road, rough and uneven in surface road surface ride turns moment varying type bicycle power-saving devices.

The technical scheme that the utility model technical solution problem adopts is: the two-wheel balanced pedaling turns that moment varying type bicycle power-saving devices comprises that chain, pedal, pedal turn one, two, axis, hinge wheel dish, be characterized in the right-hand member dress hinge wheel dish of axis, the hinge wheel dish outside fixedly is equipped with pedal and is turned one, pedal turns on one and fills pedal, the movable dress of the left end of axis balance wheel disc, the outside of balance wheel disc and pedal turn that one 180 degree are symmetrical fixedly to be equipped with pedal and to turn two, and pedal turns on two and fills pedal.

The beneficial effects of the utility model are: it is simple in structure that the two-wheel balanced pedaling turns moment varying type bicycle power-saving devices, rides laborsaving, and especially applicable long-distance, ride in rough and uneven in surface road surface and upward slope road surface.

The accompanying drawing explanation

Below in conjunction with accompanying drawing, with embodiment, illustrate.

Fig. 1 is that the two-wheel balanced pedaling turns moment varying type bicycle power-saving devices constructional drawing.

Fig. 2 is that the P of Fig. 1 is to view.

In figure, the 1-bicycle rack; 2-balance wheel disc; The 3-axis; The 4-pedal turns one; The 5-pedal; 6-hinge wheel dish; The 7-chain; The 8-pedal turns two.

The specific embodiment

Embodiment, with reference to accompanying drawing 1,2, the two-wheel balanced pedaling turns the right-hand member dress hinge wheel dish 6 that moment varying type bicycle power-saving devices is the axis 3 on bicycle rack 1, and hinge wheel dish 6 outsides fixedly are equipped with pedal and are turned 1, and pedal turns dress pedal 5 on one 4.The left end of axis 3 dress balance wheel disc 2, the outside of balance wheel disc 2 and pedal turn 4 one-tenths 180 degree symmetries and pedal fixedly is housed turns 28, and pedal turns on 28 and fills pedal 5, between hinge wheel dish 6 and bicycle minor sprocket, with chain 7, is in transmission connection.

Claims

1. a two-wheel balanced pedaling turns moment varying type bicycle power-saving devices, comprise chain (7), pedal (5), pedal turns one, two (4), (8), axis (3), hinge wheel dish (6), the right-hand member dress hinge wheel dish (6) that it is characterized in that axis (3), hinge wheel dish (6) outside fixedly is equipped with pedal and is turned one (4), pedal turns one (4) upper dress pedal (5), the movable dress of the left end of axis (3) balance wheel disc (2), the outside of balance wheel disc (2) and pedal turn that one (4) 180 degree is symmetrical fixedly to be equipped with pedal and to turn two (8), pedal turns two (8) upper dress pedals (5).
