Abstract

A single wheel bike is composed of pulley set which is on the vehicle frame as main power, speed changeable gear wheel set and large wheel on the damper, the rolling of hand operating eccentric pulley of the iniative controlled mechanism hold up the iniative end of steel wire rope to cause the large wheel rotating. Damper, wheet and human body weight are converted into power, it not only can automatically accelerate the auxilliary power, but also can perform the action of iniative driving and iniative controlling. It can be used as traffic means ridden instead of walk.

Description

A kind of pedal power device for single wheel vehicle

The present invention relates to mechanical transmission fields, especially form by vehicle frame, vehicle seat, crank shaft and foot-operated, wheel major part.

Existing this unicycle, one of shortcoming be can only as the motion performance usefulness, can not be as running vehicle; The 2nd, the amplitude that foot-operated circumference steps is big, speed is laborsaving slowly and not.

And for example a kind of autoamtic boosting of selling in the market quickens two-wheeled cycle, it is mainly by a drive end that has chain bonded assembly tension spring and steel wire tow line, be connected on the bumper by the fixed pulley under the vehicle seat, after the one-way clutch toothed chain wheel that opposite side is provided with on the chain of mouth and the transmission shaft is mutually meshing, one end of tension spring is fixed on the car back rest and sticks, car is under steam because weight relationships and wheel and ground friction vibrations, make damper spring produce contractility up and down, and affect the drive end of the steel wire tow line that is connected with bumper, drive the lonely type of one-way clutch toothed chain wheel by fixed pulley and chain and rotate and drive transmission shaft and wheel; One of shortcoming is to handle and usefulness as active force and active, and passive transmission, lonely type rotate; The 2nd, the amplitude that foot-operated circumference steps greatly, not laborsaving, volume is heavy and to occupy the space big etc.

The objective of the invention is to avoid weak point of the prior art, and provide simple in structure, light laborsaving, sturdy and durable, foot-operated is that lonely type steps up and down, and lonely type transmission is converted into and rotatablely moves, can play the auto acceleration power-assisted, again can be as active force with by power and the effect of initiatively handling.Have and occupy the little a kind of pedal power device for single wheel vehicle in space, it can be used as the running vehicle that people use always.

Purpose of the present invention can reach by following measure: comprising: vehicle frame, vehicle seat, wheel, crank throw is foot-operated, it also comprises the vehicle seat 2 on the vehicle frame, handlebar 3, template bumper 4, transmission shaft 5, wheel 6, drg 7, brake handle 8, it also comprises the pulley of a plurality of gap arrangement that the diameter that is contained on the vehicle frame 1 is different, by the assembly pulley 10 that constitutes after the single lonely type winding of the drive end of steel wire tow line 9, and be connected on the handgrip eccentric sheave 11, two ends have the power-assisted stay cord 12 of hook, each and the anchor ear 14 of eccentric handgrip 13 and bumper 4 arranged outside, the anchor ear 16 of power-assisted foot-operated 15 links to each other, exporting an end joins by the meshing 17 coupled pulleys 18 of taking turns of the assembly pulley on the vehicle frame 1 10 and the unidirectional speed change of the inboard setting of bumper 4, also be provided with paw spring 19 on it, one end panel thereon, the other end is fixed on a side of bumper 4, unidirectional speed change is meshing takes turns that the speed change of 17 mutually meshing transmissions is meshing takes turns 20 (for big or small interconnection system wheel) and mutually meshing with the meshing small flywheel of clutch 21, be located at the adjustable ground supports frame wheel 22 on the vehicle frame 1 in addition, each rotation place is a bearing 23.

Before and after the power-assisted foot-operated (15) up and down lonely type step or eccentric handgrip (13) rotates and wheel (22) and ground friction vibrations make bumper (4) produce about contractility, can affect the drive end of steel wire tow line (9), and drive meshing wheel of speed change (17) that the assembly pulley (10) on the vehicle frame (1) is connected with pulley (18), paw spring (19), the mutually meshing meshing small flywheel of meshing wheel of speed change transmission (20) (21) rotates, and drive transmission shaft (5) big wheel (6) rotation, by grasping handlebar (3) forward or ridden in left or right direction.

Because the present invention has adopted the drive end of the steel wire tow line (9) of assembly pulley (10) to link to each other with handgrip eccentric wheel (11), and by power-assisted stay cord (12) and eccentric handgrip (13), play motion by bumper (4) links to each other with the anchor ear (16) of anchor ear (14) with power-assisted foot-operated (15), exporting an end is connected on the pulley (18), make that its transmission gear shift is meshing takes turns (17) (19) (20) (21), and transmission shaft (5) drives big wheel (6) rotation; Make its can play respectively initiatively use or use simultaneously initiatively handle grasp that car travels soon at a slow speed, can play the effect of quickening power-assisted or passive use automatically step by step again; Be converted into the circumference rotation and output torque power by lonely type, and make this power and work done.

This device have take up room little, light and flexible, speed freely and cost is low can be used as the running vehicle that people use always.

The present invention can also come this to arrive by following measure, steel wire tow line (9) and (10) also can be nylon ropes, chain-type drive etc., eccentric rainwater in puddles the wheel (11) of connected handgrip also can be that toothed chain is wheeled, help stay cord (12) also can be integral type with steel wire tow line (9), directly with anchor ear (14) or ride and anchor ear (15), (16) link to each other separately, eccentric handgrip (13) can not established yet, also can set up or two establishing, bumper (4) can not established yet, unidirectional speed change is meshing, and to take turns (17) also can be that unidirectional height closes change wheel, the paw spring (19) of pulley (18) can not established yet, also can be by the chain tooth sprocket wheel, tension spring, replacements such as spring formula, also can be that eccentric speed change is wheeled etc., speed change is meshing takes turns (17), (20) meshing small flywheel (21), also can set up or two establishing, also can increase or dwindle its diameter proportion or increase and decrease number or group number etc., adjustable ground supports frame wheel (22) can not established yet, also fixable type, also can be big or little etc., the bearing of each rotation place (23) also can be with axle sleeve type replacement etc.The present invention can be two-wheel, three-wheel vehicle etc., also can increase and decrease the number and group number of assembly pulley (10) according to the size requirement of the divine force that created the universe, increase or dwindle the single diameter etc. of pulley, also ratio, size increase or dwindle the meshing power wheel of speed change accordingly, increase or reduce, adapting to various types of passive machineries, and as main power machines or by power and use etc.Can also be with various types of driving engines of routine, electrical motor, the magnetic motivation, oil press, air engines etc. are provided with high-performance driving engine of various types of low-powers or engine etc. with the principle of work of this device, assembly pulley (10) also can replace or both convolutions replace or with the pattern replacement of relay bar etc. with laborsaving lever, in a word, all machinery of power that needs can be provided with the principle of work of this device, also can be fixed type power or driving engine etc., but also can utilize its antagonistic force and make opposite merit, as: automatic brake, retarder and diff or their integrated function formula etc.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a kind of roman scheme drawing of pedal power device for single wheel vehicle;

Fig. 2 is the assembly pulley (10) of this device and the scheme of installation of power-assisted stay cord (12);
