Description

The rickshaw torque transfer

The utility model belongs to transport facility, especially the device of a kind of transferring power on the rickshaw.

At present the rickshaw as transport facility has three-wheel vehicle and two-wheel bicycle, have on this type of car with wheel be associated in by movable sprocket and the drive sprocket that is associated in axis, drive by movable sprocket by the chain drive sprocket, thereby drive wheel.The rotation of axis is to promote its left and right end vertical fixing install, be separated by cranks of 180 degree by manpower to realize, the people must ceaselessly do 360 rotatablely moving of degree and stir crank and rotate around axis, could roll by the transmission drive wheels of power and advance, the normal person rotates with the pedal of pedal crank end, and the crank end handle on the hand axis that is installed in the front for disabled persons rotates.In the transmittance process that carries out power, it is moving that the people need do rotation, and its application of force direction can not be constantly all perpendicular to the crank as the arm of force, and when out of plumb, a part of power of people has been done useless moving being wasted; Moreover to do the 360 giant single motions of spending, and can tire out too greatly because of amount of exercise, more inconvenient to the elderly and disabled person.

The purpose of this utility model provides a kind of torque transfer of rickshaw not only laborsaving but also easy to use.

For achieving the above object, the utility model is achieved like this: the left and right sides side arm direction at driving support seat front central and the moving bearing of saequential transmission has fixed support, concentric transverse holes is passed and arranged on left and right sides arm and support, rotatably support has left and right two-semiaxle in the hole, two-semiaxle is installed relatively, one end frame is in bracket holes, the other end stretches out left and right side arm, its end is fixed with the crank perpendicular to semiaxis respectively, crank end two outsides are fixed with the little axle perpendicular to toggle-action lever, on the little axle revolving meber are housed; On the two-semiaxle between support and the left and right side arm, be installed with rocking arm respectively, and be about 90 angles of spending with crank; On the left and right side arm of driving support seat rear end, rotatably support has the sprocket shaft that is parallel to semiaxis, it stretches out the outer end of side arm and is installed with drive sprocket, on the sprocket shaft in the middle of the driving support seat two side arms left and right two bicycle use ordinary single-stage flywheels are housed, the oblique unanimity of interior ratchet of its overcoat, its fuse is fixed on the wheel shaft; There is tween drive shaft to be rotatably supported on the left and right side arm at the driving support seat middle part, be fixed with left and right minor sprocket on the tween drive shaft, the line of centers of its transverse tooth thickness degree direction respectively with the line of centers of the rocking arm line of centers at two ends and the gear teeth thickness direction on the ordinary single-stage flywheel in one plane; One end of left and right sides chain is connected the rocking arm top versatilely, the other end from ordinary single-stage flywheel top around downward cross the bottom after, respectively with forward with after oppositely walking around minor sprocket, be connected versatilely on the gear teeth of same angle position of left and right sides minor sprocket.

During use, driving support seat is fixed on the middle shaft position of former rickshaw, an end of driving chain is enclosed within on the drive sprocket on the driving support seat, the other end be enclosed within wheel link by on the movable sprocket.When the people promotes revolving meber on the left crank downwards, left half axle rotates, driving left rocking arm upwards lifts, the pulling left chain also rotates the ordinary single-stage flywheel on the left side, one of a forward oppositely twines the left and right sides minor sprocket of chain owing to be fixed on the same axle, one of them discharges chain, another twines chain, because the effect of the very heavy and ratchet in the ordinary single-stage Case of fly-wheel, one drives sprocket shaft and rotates, drive sprocket on it is also along with rotation, drive passive sprocket rotation by chain, travel, and another ordinary single-stage Case of fly-wheel is in and oppositely trackslips thereby drive the wheel powered vehicle, and counter draw right rocking arm left the minor sprocket direction tilt, right crank has been drawn and lifted; When the people promotes right crank downwards, as above-mentioned same process, make the common single flywheel on right side drive sprocket shaft with above-mentioned same direction rotation, drive sprocket shaft, drive sprocket, by movable sprocket and wheel, same powered vehicle to overtake, and the Case of fly-wheel in left side trackslips and spurs left rocking arm and left crank once more, and the people is as long as constantly exchange presses down left crank and right crank like this, and vehicle just can be continuously to overtake.

After adopting this kind structure, because people's throw crank becomes the right and left handle drive wheels of alternately buckling downwards by the rotations of 360 degree, therefore can keep people's application of force all the time perpendicular to the crank of making the arm of force substantially, reduced the manpower that flogs a dead horse and waste like this, the people does not do the spiral arm motion of large amount of exercise when stirring crank simultaneously, is specially adapted to the driving of bicycle, three-wheel vehicle and Wheelchair car.

The utility model is described in further detail below in conjunction with drawings and Examples.
