When the utility model works, the T-shaped cutting strip is stepped from top to bottom, which leads a steel wire in the U-shaped plate to be straightened and bent, and the bicycle runs. The utility model has the advantages that the volume is small, and the utility model can realize stepless speed variation.
Description
The utility model relates to a kind of new bicycle, and characteristics are bicycles of reciprocal transmission variable-ratio.
Existing bicycle is chain gear, step change, and speed range is little, and cost is higher.
The purpose of this utility model is: improve at above-mentioned deficiency, propose and design the variable speed bicycle of this reciprocal transmission.
Technical solution of the present utility model is: replace chain gear with steel rope, upwards move down with the T type cutting that is inserted in the U template, make its interior steel wire become curved change and directly drive to advance, utilize the slider on the rear-wheel hub axle, the diameter that changes flywheel just can be realized stepless change.
It is characterized in that: wheel good fortune bar is cross.
It is characterized in that: change-speed box is made up of 2 parts on the hub, above close take turns that part of a steel bar, a spring and 3 post tips is arranged, and second portion links to each other with slider by ball.
It is characterized in that: slider is gone up slide plate by slide plate on the hub and axle and is formed by bolted connection, by the nut adjusting motion of shaft end.
It is characterized in that: the T type is transplanted a cutting the bottom, and that the pulley number is housed is right, and the distance between the every pair of pulley should be a bit larger tham the diameter of small sheave (8).
It is characterized in that: be wound with a few transmission steel wires on the change-speed box, can the both sides change-speed box be linked up by steel wire and pulley, this steel wire top is fixed on the guidepost of lower left, U template front side, and end is not by rear side lower left guidepost, on pulley shown in Figure 8 (11).
It is characterized in that: a pin that is connected with spring is arranged on the pulley (11), on the pin plate (21) on opposite a plurality of pins hole is arranged with it.
It is characterized in that: spring is equipped with at brake bar middle part.Stretcher is arranged at the bottom, on the afterbody brake frame brake rubber block (like glue plastics etc.) is installed.
It is characterized in that: all there is flywheel on trailing wheel two limits, and there is a pulley centre, with the mode transmission of rope-chain-rope-chain-rope.
It is characterized in that: the barb bolt middle part is connected with spring, and afterbody is connected with steel wire, and an other end of steel wire connects locating tab (22), and locating tab can put in the pin hole of pin plate.
Principle of work of the present utility model is, when steel rope at winding number on the change-speed box after week just can on change-speed box, not skid when stressed because friction increases steel rope.
The utility model has the advantages that: volume is little, cost low energy realizes stepless change.

Below, describe embodiment of the present utility model with reference to the accompanying drawings in detail.
As shown in Figure 5, a spring is arranged on the change-speed box (13), a steel bar and 3 post tips, spring one end is connected on the steel bar, and an end is connected on the post tip (24), and steel bar (23) serves as that axle is taken root with the post tip (25), under the support of the post tip (21), can stir the trailing wheel spoke, make the trailing wheel running drive to advance, if the change-speed box contrarotation, then steel bar (23) can slide between many spokes under the effect of spring (22).
Slider is by slide (15) as shown in Figure 4, (19) and bolt (16) form, it is the same with vehicle frame to be motionless, change-speed box (14) relatively rotates on slide plate (15) by ball, just transfer loose nut (9) if will speed up, an axial component that is produced by the steel wire on change-speed box can make change-speed box (14) automatically slider be pushed open by ball like this, flywheel diameter is diminished, if will slow down, with regard to tightening nuts (9), slider advances change-speed box (14) by ball, make change-speed box (13), (14) pitch smaller, flywheel diameter has just increased.
As shown in Figure 7, when riding, earlier left foot is stepped on a left side and transplanted a cutting (2) then steel rope bending, the flywheel left-hand revolution that left change-speed box is formed, the driving car advances, and steel rope is by pulley (5), the flywheel contrarotation that the change-speed box on the right is formed, steel bar (23) is under spring (22) effect, can slip over spoke (1) and be not stuck, right transplant a cutting to become under the straight thrust that produces at the bottom steel wire be forced to rise to the top, and then step on right the cutting with right crus of diaphragm.And so forth so that infinite.
As shown in Figure 2, when T type cutting in front side moves down into lowest order, can be with the head of the barb bolt in U template front side, put between corresponding with it a pair of (the cutting bottom) pulley, and be located at the top of steel wire between the pulley, like this when the rear side cutting moves down, steel wire on this barb bolt is just blocked by barb bolt, move no longer and become straight, so the variable-operation length of steel wire just will reduce, the result just makes rear side transplant a cutting can't move down into extreme lower position, at this moment the pin (22) on the pulley shown in Figure 8 (11) will be extracted the pin hole, discharge steel wire, rear side is transplanted a cutting move on to extreme lower position, then pin is inserted on the pin plate from its nearest pin hole, again with a barb bolt of U template bottom rear, insert between cooresponding with it a pair of (T type cutting bottom) pulley, and be located at this top to steel wire between the pulley, the slack-off process of whole like this speed has just been finished.Can certainly insert the barb bolt more than 2 or 2, make speed slower, but all barb bolts can not be inserted simultaneously, if want speed to accelerate, only need withdraw from the both sides barb bolt, the steel wire withdrawal that pulley (11) is emitted gets final product.Usually, barb bolt stretches out under the effect of spring, if will withdraw it, then spurs its afterbody steel wire, because the other end of steel wire is connected on the locating tab, so only need the pin on the pin plate is extracted, inserting another hole is the regracting barb bolt, shown in figure (2).This pin plate is the same with pulley (11) pin plate, can fix (using bolt nut) optional position at vehicle frame.
