Abstract
The utility model provides an up -and -down motion is made to the piston that bicycle booster unit who stirs with convex air piston, it when stepping on ratchet chain dish through the manpower, makes coaxial cam rotatory, drives bicycle riser both sides to form compressed gas, and the storage is in the gas holder. When opening the supplying gas during the switch of gas holder, in compressed gas got into the convex piston cylinder of ratchet chain dish side, reciprocating motion was made to the pawl that promotes on the convex piston rod terminus guide block to the messenger has the ratchet chain dish of concave tooth and makes circular motion. The utility model discloses a characteristics have: what do all the time when ratchet chain dish is stepped on to the manpower all is the useful work - - - or make the bicycle travel, and perhaps make the gas holder aerify, , the pneumatics can overcome that compare that bigger resistance is met to ordinary bicycle and speed of traveling and ordinary bicycle match when making a concerted effort with the manpower to it freely adjusts the characteristics of riding passerby's health fatigue strength to reach.
Description
Art
The utility model relate to a kind of belong in traffic and transport field to unpowered vehicle install engine installation, especially give bicycle be representative rickshaw install work-saving device.
Background technology
At present, known common bicycle is that power drives with manpower, and the shortcoming of this type of drive is, when bicycle reaches certain speed of a motor vehicle, continues to step that crank then does is idle work, otherwise does not just step crank and do not do work; Another kind of gas motor drives, and the mode one for gas motor air feed travels front bottled gas, when gas is finished the bicycle that rear foot treadmill becomes common; The another kind of mode for gas motor air feed is the mode air feed manually stepping gerotor pump.The final object all in order to make gas revolution just can reach power-assisted of mode of these two kinds of air feed.And driving the shortcoming of bicycle to be with gas motor, speed has too fast shortcoming.And although the utility model is also manpower air feed, the mode of air feed is different, and the mode of driving is also different, is no more than again the speed of common bicycle running simultaneously.
Summary of the invention
In order to overcome existing bicycle when driving with manpower or do not do work, or flog a dead horse, or with there being the shortcoming of excessive velocities during gas motor.The utility model provides one makes manpower no matter when step bicycle, is all doing useful work, avoids the drawback making bicycle excessive velocities under steam with gas motor simultaneously.
The utility model solves the technical scheme that its technical matters adopts: on bicycle standpipe, left and right respectively arranges a piston cylinder, its cylinder body one end and standpipe make hinged joint, its other end piston-rod end establishes a bearing to contact with the cam at the axis two ends of bicycle, the standpipe of bicycle is provided with a spacing anchor ear, be used for limiting piston cylinder, when without piston, spacing anchor ear and standpipe dos-à-dos are connect, is then disconnected the gas circuit of artificial air feed.And the side of chain drum on axis is provided with two circular arc pistons, the cylinder body of its piston is fixed by the fixed block of the Chain stay at bicycle, the end of its piston rod is an orienting lug, ratchet on orienting lug, and chain drum itself is a ratchet, its side is processed with a series of recessed tooth matched with the ratchet on orienting lug, and the crank on bicycle and the angle of its axis are obtuse angle, makes it not interference with circular arc piston when rotated.The lower pipe of bicycle is provided with storage tank.When stepping the ratchet chain disc pesed on axis when manpower, while driving chain, cam is rotated, and cam then makes piston move up and down, gas is made to be pressed into storage tank by check valve, when the gas of storage tank reaches certain pressure, by the switch on operation handlebar, open the valve of storage tank, pressure gas then inputs two circular arc pistons, make circular arc piston rod sequential telescopic, the ratchet chain disc pesed promoted on axis circles, thus drives bicycle automatic running; When climbing or want afterburning, also can make two circular arc piston simultaneous retractables, namely artificial and aerodynamic resultant makes chain drum circle.When the pressure of storage tank exceedes setting pressure, pressed gas inputs in two circular arc piston cylinders automatically, reaches both automatic runnings, the object reduced pressure again, if when being also not enough to decompression, the safety valve at this moment on storage tank is opened automatically, reaches the effect of double insurance.
The beneficial effects of the utility model are, are all doing useful work when stepping crank each time, or are step chain drum to make bicycle running, or are giving storage tank aerating.When human body does not do work, bicycle then by pneumatic acting automatic running, thus makes bicyclist reach the object of the strength at repeated alternation of free adjustment health.

Detailed description of the invention
In fig. 1 and 2, when bicyclist step obtuse angle crank (18) make ratchet chain disc pesed (5) make clickwise time, drive chain (15) motion thus while making bicycle running, also cam (16) has been driven to make clickwise, and the bearing piston bar (19) contacted with cam and piston (21) do relative motion, make in pressure gas press-in storage tank (3) in piston cylinder, when bicyclist needs power-assisted or automatic running, open aspirated switch (1), circular arc piston (4) is made to be filled with pressure gas, then circular arc piston rod makes fore and aft motion, thus make circular arc piston rod drive the ratchet (13) on orienting lug (9) reciprocating, the ratchet chain disc pesed (5) stirring recessed tooth (11) place circles.
The effect of the spring (20) in piston cylinder keeps bearing piston rod (19) to contact with cam all the time.
The effect of spring (8) ensures all the time to make ratchet (13) return to incipient state when the pressure of circular arc piston reduces to zero in fig. 1 and 2; Orienting lug (9) keeps ratchet (13) not to be shifted towards recessed tooth (11) all the time.Fixed block (6) makes circular arc piston be positioned on the side of ratchet chain disc pesed (5), keeps the ratchet (13) on orienting lug (9) and recessed tooth (11) to closely cooperate.
