Abstract

Every time an assembled wheel disc rotates for a circle, the assembled wheel disc and a flywheel (a small flywheel on a rear wheel of a bicycle) have different transmission ratios at different angles. An interval with the smallest transmission ratio is enabled to be corresponding to a dead point position of a stepping arm, an interval with the largest transmission ratio is enabled to be corresponding to an interval, supplying most force, of the stepping arm, dead points are overcome, and efficiency is improved. Due to the fact that the assembled wheel disc is of an assembled type, an adjustment amount is reserved in each assembling procedure, and therefore both angles and positions can be adjusted, teeth can be replaced, and a bicycle with the assemble wheel disc is practical, and has more obvious advantages than a common bicycle in the processes of racing, climbing and headwind riding in test riding. The assembling modes of the assembled wheel disc have the following types: a single-unit wheel disc, a double-unit wheel disc and a wheel disc capable of automatically adjusting the transmission ratio. According to the single-unit wheel disc, a group of chain wheels is arranged on the single surface of a main plate. According to the double-unit wheel disc, each surface of the main plate is provided with a set of chain wheels, with the two sets of chain wheels being different in specifications. According to the wheel disc capable of automatically adjusting the transmission ratio, small chain wheels can move on the main plate, when load is large, the small chain wheels move inwards, and when the load is small, the small chain wheels move outwards and move to a position with the largest transmission ratio.

Description

The assembly type wheel disc

Technical field: bicycle field

Background technology:

Bicycle is circular wheel disc at present, often circles, and all has lower dead point, and efficient is not high, for overcoming the dead point, raises the efficiency, and designs this wheel disc.

Groundwork:

This wheel disc often circles, and from flywheel (being contained in the small flywheel on bicycle rear), different transmitting ratios is arranged in different angles, and the interval of transmitting ratio minimum is corresponding with the dead center position of stepping on arm.The interval of transmitting ratio maximum with step on interval corresponding to power of arm, so overcome the dead point, improved efficient.Because be assembly type, each assembling link leaves adjustment amount, and angle and position can suitably be adjusted, and changeable-teeth is very practical, rides through examination, no matter competes for speed, climbs or against the wind, all have a clear superiority in than common car.

Basic assembling form has following several:

(1) single group wheel disc: the main board single face is installed one group of sprocket wheel, photo 1 be mainly look, the 2nd, the state after backsight, 3 is mounted on car.

(2) two groups of wheel discs: one group of sprocket wheel is respectively installed on the main board two sides, and two groups of sprocket wheel specifications are different, photo 4 be mainly look, the 5th, backsight, the 6th, mode of operation.

(3) self-regulated transmitting ratio wheel disc: when load when large, minor sprocket by in move, load hour, the outer maximum transmission ratio position of moving on to automatically.Photo 7 is self-regulated transmitting ratio wheel disc mode of operations.

Self-regulated transmitting ratio wheel disc implementation is as follows:

Open four guide grooves (cross is vertical) and join Four-slider on main board, four same specification minor sprockets with identical tooth position (line of centers two heel teeths are symmetrical), are separately fixed on Four-slider.Minor sprocket center pin hole, the guide groove of then packing into is in the situation that the actual engagement of chain is determined the connecting rod size by design specification.

Deng long connecting rod, four minor sprocket active pins are connected.Arm and wheel disc connecting rod and spring are stepped in installation.

Principle of work:

Four sprocket wheels are in the interlock process, and two adjacent centre of sprocket are apart from constant, and angle of contact is complementary, make chain transmission engagement and withdraw from unaffectedly, and diagonal angle two centre of sprocket are apart from changing, and reach to change transmitting ratio purpose (with the small flywheel of back wheels of vehicle).

Claims

1. an assembly type wheel disc, is characterized in that assembly type.

2. capable of regulating.

3. changeable-teeth.

4. often circle, from small flywheel (small flywheel after being contained in bicycle), different transmitting ratios is arranged in different angles.

5. list is organized wheel disc: the main board single face is installed one group of sprocket wheel.

6. two groups of wheel discs: one group of sprocket wheel is respectively installed on the main board two sides, and two groups of sprocket wheel specifications are different.

7. self-regulated transmitting ratio wheel disc: minor sprocket can move on main board, loads when large, move in minor sprocket, and load hour, outer moving automatically moves to the maximum transmission ratio position.
