Description

Manpower bicycle's treadle swinging driver.

The utility model relates to a kind of manpower bicycle's actuating device, is a kind of manpower bicycle's treadle swinging driver.

Present any manpower bicycle, no matter be bicycle, or three-wheel vehicle, its actuating device all is made up of vital partss such as left and right foot-driven lever, big trochal disc, axis, chain and rear flywheels basically, left and right foot-driven lever is 180 ° of center symmetries, and is connected to one with axis, big trochal disc.The people firmly steps left and right stretcher along 360 ° of full circle Zhou Xuanzhuan, and treadle is sent to rear flywheel with propulsive effort by big trochal disc and chain, thereby drives trailing wheel, and drives the front-wheel rotation, and the manpower bicycle is advanced.

By the body mechanics as can be known, the people is under the sitting posture situation, the collapsing length of both legs is limited, and the both feet revolution steps the restriction that frequency is subjected to fatigue strength condition, increases treadle length and is subjected to ground-surface restriction again, therefore, make the available man-power bicycle driver exist the defective that can't overcome, promptly under the state that keeps human body normally to step, can't pass through the lengthening arm of force, just increase the way of treadle length, reach raising speed and labour-saving purpose.

The purpose of this utility model is exactly the defective that is to overcome the available man-power bicycle driver, improve the actuating device stress condition, become foot-operated gyroscopic movement and be foot-operated crank motion, take the arm of force that extends, promptly increase the way of foot-driven lever length, make under equal driving power, increase drive torque, improve speed and laborsaving to greatest extent, thereby a kind of new manpower bicycle's treadle swinging driver is provided.

Manpower bicycle's treadle swinging driver comprises driving power-transfer clutch, gap bridge transmission device, treadle, treadle interlock pulley and back plate.Constitute the chain sprocket drive pair by the driving big trochal disc that drives power-transfer clutch and the driven minor sprocket of gap bridge transmission device.Driving power-transfer clutch and gap bridge transmission device divides other to be fixedly connected on left and right two back plates in its both sides by the axle drive shaft and the axle of passing a bridge.Treadle interlock pulley is positioned at and drives the power-transfer clutch top, it is hung and is hung with flexible traction spare on the pulley, its two ends respectively around and be connected on two inner side slots that drive left and right two sheaves in power-transfer clutch axle drive shaft two ends, and on left and right two sheaves, two outer side slots around and bonded assembly flexible traction spare, be connected with traction spindle nose on the left and right treadle respectively.The treadle tail end then flexibly connects with the axle of passing a bridge.

When people press down with the foot down left and right arbitrary treadle plate, treadle is that the center of turn fulcrum rotates with the axle of passing a bridge, and affect by flexible traction spare on the traction spindle nose and to drive the corresponding sheave of power-transfer clutch and rotate, propulsive effort is set isolator wheel drive big trochal disc in sheave and sheave, be delivered to the driven sprocket of gap bridge transmission device then through chain, be resent to manpower bicycle's hind axle, and then drive trailing wheel, the drive front-wheel rotates, and finishes to drive and advances.

A left side, the interlock of right treadle is by hanging pulley by a flexible traction spare and an institute bonded assembly left side, right two sheaves are finished jointly, when arbitrary treadle is depressed driving, the crop rotation of traction respective grooves rotates counterclockwise, at this moment, corresponding isolator wheel is in bonding state, the driving big trochal disc rotates, sheave inner side slot (i.e. the groove of close big trochal disc) rolling institute bonded assembly flexible element, affect another sheave of flexible element other end bonded assembly through hanging pulley, it is clockwise rotated, corresponding isolator wheel is in released state, does not drive big trochal disc and rotates, and this sheave then draws another treadle that is connected and lifts return.Vice versa.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the utility model front view

Fig. 2 is the utility model birds-eye view

Fig. 3 is the utility model left view

Introduce embodiment of the present utility model below in conjunction with accompanying drawing.

This device is formed by driving power-transfer clutch, gap bridge transmission device, treadle, treadle interlock pulley and back plate etc.

Drive power-transfer clutch and comprise axle drive shaft (1), centre-driven big trochal disc (2), left and right two symmetrical sheaves (3) and the embedded two isolators wheels of sheave (4).The gap bridge transmission device comprises pass a bridge axle (5), duplex gap bridge sprocket wheel (6) and (7), and wherein minor sprocket (6) is for driving the driven sprocket of big trochal disc (2), and sprocket wheel (7) can be sent to propulsive effort manpower bicycle's hind axle.Treadle divides left and right two symmetrical treadles (8) and end pedal (9), and two symmetrical treadle (8) inboards are fixed with traction spindle nose (10), have conduction chain (11) respectively with drive left and right two sheaves of power-transfer clutch (3) two outer side slots around and be connected.For making things convenient for conduction chain (11) to connect, traction spindle nose (10) should be positioned at and drive the power-transfer clutch front position.Treadle interlock pulley contains hangs pulley (12), sheave shaft (13) and pulley bracket (14), hang and be hung with steel rope (15) on the pulley (12), with drive left and right two sheaves of power-transfer clutch (3) two inner side slots around and be connected, pulley bracket (14) base plate is captiveed joint with manpower bicycle's beam, and it is in drive power-transfer clutch top forward position and be advisable.Back plate divides left and right two back plates (16), captives joint with the adapter plate (17) on manpower bicycle's beam respectively.Drive power-transfer clutch, gap bridge transmission device and then be fixedly connected on left and right two back plates in both sides (16) by axle drive shaft (1), the axle (5) of passing a bridge respectively, treadle (8) is flexibly connected by its tail end hole and the axle (5) of passing a bridge.

Manpower bicycle's treadle swinging driver compact conformation, reasonable in design, volume is little, and is in light weight.Install and use on bicycle, three-wheel vehicle, carry out repeatedly road test, effect is fairly obvious, because stress condition changes, treadle is a wobble drive, and treadle suitably extends, under equal legpower, facts have proved that bicycle speed can improve 35～40%, the three-wheel vehicle load-carrying can improve 25～30%.Moreover treadle is that on-fixed is connected with wheel disc, and the driving of treadle and return interlock are ridden freely, rotate flexibly, move light, safe and reliable.
