Abstract
The utility model discloses a driving mechanism of a bike. The utility model has a bike as the carrier. A rear fork 10 is connected to a fly wheel 11 via a rear axle. The flying wheel 11 is connected to a big sprocket wheel 6 via a chain 9. The utility model also includes foot-operated levers 1 and 2. The utility model is characterized in that the big sprocket wheel 6 is installed through an axial rod 8 on the outer side of the rear fork 10 diagonally above the flying wheel 11. The axis 8 on the left and right sides of the big sprocket wheel 6 is installed with rocker arms 5 and 7. The ends of the foot-operated levers 1 and 2 are flexibly connected to the rear fork 10. The rocker arms 5 and 7 are flexibly connected to the rear part of the foot-operated levers 1 and 2 via pull rods 4 and 3. The utility model is an ideal driving mechanism of bikes.
Description
The bicycle driving mechanism that the utility model relates to belongs to a kind of driver train that is used in two wheel bicycles, is a kind of a kind of bicycle driving mechanism that flywheel rotates that drives by pumping specifically.
Existing bicycle driving mechanism, the gear transmission driver train that front-rear reciprocation movement can not speed change is arranged, the gear transmission driver train that the front-rear reciprocation movement variable-ratio is arranged, but it is short with foot-operated lever arm of force having common disadvantage, the strength that needs the people to pay is big, the requirement of speed of a motor vehicle out of reach, at present a kind of a kind of bicycle driving mechanism that drives the flywheel rotation by pumping was not seen.
The utility model is intended to improve the deficiency of above-mentioned prior art, and a kind of lever principle of utilizing is provided, and makes pedal lever arm of force lengthening, drives a kind of bicycle driving mechanism that flywheel rotates by pumping.
In order to achieve the above object, the utility model is to realize like this, it is to be carrier with the bicycle, connect a flywheel 11 at rear vehicle fork 10 by a car rear axle, flywheel 11 is connected on the big chain wheel 6 by chain 9, it also comprises a pedal lever 1,2, be characterized in that big chain wheel 6 is installed in rear vehicle fork 10 outsides of flywheel 11 oblique uppers by axostylus axostyle 8, on the axostylus axostyle 8 of the left and right sides of big chain wheel 6 connecting lever 5 is installed, 7, pedal lever 1,2 end is movably connected on the rear vehicle fork 10, connecting lever 5,7 respectively by pull bar 4,3 are movably connected in pedal lever 1,2 latter half of on.
Its principle of work is as follows: with pin pedal lever 1,2 up-and-down movements, through pull bar 3,4 pulling connecting levers 5,7, thereby big chain wheel 6 is rotated forward, drive flywheel 11 by chain 9, reach driving back wheels of vehicle purpose to overtake.
The utility model is simple in structure, and is novel, pedal lever arm of force lengthening, and both laborsaving, speed is fast again, under bicycle main body unmodified situation, can supportingly use, and is present a kind of more satisfactory bicycle driving mechanism.
Description of drawings:
Accompanying drawing is the supporting structural representation that is installed on the bicycle main body of the utility model.
The explanation of accompanying drawing drawing:
1 pedal lever, 2 pedal levers, 3 pull bars, 4 pull bars, 5 connecting levers, 6 big chain wheels, 7 connecting levers, 8 axostylus axostyles, 9 chains, 10 rear vehicle forks, 11 flywheels.
In order to understand better and to implement, it is as follows with the accompanying drawing to be that embodiment further specifies below:
This driver train is to be carrier with existing bicycle, flywheel 11 is installed identical with existing bicycle, by car rear axle and back wheels of vehicle, rear vehicle fork 10, the shelf support connects, big chain wheel 6 is installed in rear vehicle fork 10 outsides of flywheel 11 oblique uppers by axostylus axostyle 8, and on the axostylus axostyle 8 of the left and right sides of big chain wheel 6, connecting lever 5 is installed, 7, drill with ferrule one axis hole on rear vehicle fork 10 at first, with connecting lever 5, a hole is respectively bored at 7 two ends, axostylus axostyle 8 is through on the axis hole, big chain wheel 6 is positioned on the axostylus axostyle 8 in the rear vehicle fork outside, with connecting lever 5,7 be positioned on big chain wheel 6 about the outside, fix by bearing pin, and chain 9 be buckled on big chain wheel 6 and the flywheel 11; The terminal head of pedal lever 1,2 is respectively bored a hole, a hole will respectively be bored on the pole of rear vehicle fork 10 both sides, reach flexible connection by screw, nut, the latter half of axis hole that respectively bores at pedal lever 1,2, an axis hole is respectively bored at pull bar 3,4 two ends, respectively pedal lever 1,2 and pull bar 3,4 lower ends are reached flexible connection, respectively the upper end and the connecting lever 5,7 of pull bar 3,4 are reached flexible connection again by a screw, nut by a screw, nut.Pedal lever the 1, the 2nd, the 3-4 of the brachium of existing pedal lever for bicycle are doubly.
Its principle of work is, pedal lever 1 is downward, and 2 of pedal levers make progress, and drives connecting levers 5,7 by pull bar 4,3 simultaneously, when pedal lever 1 downwards the time, connecting lever 5 motions are at low spot, and connecting lever 7 is at high point, by constantly pedaling pedal lever 1,2 simultaneously, connecting lever 5,7 constantly replaces up-and-down movement, drive big chain wheel 6 motions, big chain wheel 6 drives flywheel 11 by chain 9, reaches to drive trailing wheel purpose to overtake.
