Abstract
A laborsaving and rapid speeding up triangular chain teeth tray of bicycle belongs to a triangle shape consisting of three identical equilateral sides. The three identical equilateral sides have the same curvature and teeth. The angle formed by the connection of the three identical equilateral sides is semi-elliptical in shape. The triangular chain teeth tray is connected and fixed with a central axis, a big bend and a flywheel. The erected angle can be used to pull a lever forward when rotating, thus playing the role of laborsaving.
Description
Affiliated technical field:
The utility model relates to the fast zipper saw disc device of the laborsaving speed of a kind of bicycle, and is especially doubly poor bigger at front and back sizes zipper saw disc, scrunches with under the big situation of force intensity, can play the laborsaving triangle zipper saw disc of pick up speed effect rapidly again.
Background technology:
At present, the power of known bicycle is to kidnap the moving zipper saw disc that fixes with it greatly and move in a circle by scrunching, and leads to flywheel chain chain wheel that chain passes to the back to power again and drives it and advance.But up to the present, the zipper saw disc that all bicycles use and the technical design of the zipper saw disc on the flywheel all are to be circular configuration, therefore, big or small zipper saw disc was doubly poor before and after the principal element of the laborsaving degree degree of decision bicycle depended on, big or small zipper saw disc was doubly poor big more both, its speed is fast more, but scrunches effort more.Doubly poor more little, speed is slow more, scrunches laborsaving more.So far, a moving week of revolution all must be to carry out under the state of exerting oneself at full capacity, and the result has formed " wanting speed soon just can not be laborsaving ", the contradiction situation of " wanting laborsaving fast with regard to impossible velocity ".Especially going up a slope and seeming more outstanding against the wind the time.
Summary of the invention:
In order to overcome this speed and labour-saving deficiency, the utility model provides, and a kind of " the fast zipper saw disc of the laborsaving speed of bicycle triangle, " not only solved above-mentioned deficiency, and reaches not only laborsaving when scrunching but also the purpose of pick up speed rapidly.
The scheme that its technical matters that solves the utility model adopts is:
By three equilateral triangle zipper saw discs that constitute, be used for turning greatly and the installing and using of flywheel chain chain wheel, all be fulcrum when using with the axle center.Fashionable when the arbitrary equilateral teeth and the chain tooth of triangle zipper saw disc, what play only is the transmission transitional function meshing with chain, need not use any power.This district is for " laborsaving district ", and when being in the position that erects above equilateral cross " angle " that form forwards to by three, what should " angle " play is the afterburning forward laborsaving effect of moving of lever, and this district is " province LJL district ".Because under the combined action in " laborsaving district " and " province LJL district ", solve and reached the laborsaving purpose of pick up speed rapidly again.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1, be the plan view of the utility model first embodiment.
Fig. 2, be the plan view of the utility model second embodiment.
Among Fig. 1: equilateral (2) half-elliptic " angle " (3) triangle zipper saw disc center holes (4) zipper saw disc that triangle zipper saw disc teeth (1) have radian turns (5) greatly
Among Fig. 2: flywheel central shaft hole (6) flywheel (7)
The specific embodiment:
In Fig. 1, the equilateral teeth (2) that have radian play meshing transmission effect with fashionable of chain tooth.When zipper saw disc was rotated further, the lever laborsaving effect of afterburning pulling was forward played in " angle " (3) that erect.The center hole of triangle zipper saw disc and axis, turn and be connected to a fixed greatly, rotate to drive the triplet chain wheel.
In embodiment illustrated in fig. 2, triplet chain wheel half-elliptic " angle " (3) was drawn forward and plays the laborsaving effect that torsion is moved forward that strengthens when moving when triangle zipper saw disc teeth (1) were used for rear flywheel (7).
The fast zipper saw disc of the laborsaving speed of a kind of bicycle triangle, it is made of three half-elliptic " angle " that three identical equilateral and equilateral intersections that have a lonely degree form, and it is characterized in that: zipper saw disc is the equilateral triangle shape.The periphery of equilateral triangle have can be mutually meshing with chain teeth.
A kind of can be laborsaving " the fast zipper saw disc of the laborsaving speed of a kind of bicycle triangle " of pick up speed rapidly again, be by three identical equilateral triangles that constitute.Three identical equilateral all have identical lonely degree and teeth.Three identical equilateral " angles " that form that cross are half elliptic, triangle zipper saw disc and axis, turn greatly, flywheel is connected to a fixed, and utilizes the angle that erects during rotation, plays the afterburning forward laborsaving effect that spurs of lever.
Claims (2)
1, the fast zipper saw disc of the laborsaving speed of a kind of bicycle triangle, it is made of three half-elliptic " angle " that three identical equilateral and equilateral intersections that have a radian form, and it is characterized in that: zipper saw disc is the equilateral triangle shape
2, the fast zipper saw disc of the laborsaving speed of a kind of bicycle triangle according to claim 1 is characterized in that: the periphery of equilateral triangle have can be mutually meshing with chain teeth.
