Abstract

The utility model relates to a hydraulic transmission bicycle which changes a traditional mechanical driving mechanism to a hydraulic driving mechanism composed of a hydraulic oil pump, a high-pressure oil pipeline, an oil return pipe and an oil motor, and the pressure generated by the hydraulic oil pump drives the oil motor to be rotated so that the bicycle is driven to move forwards. The utility model overcomes the defects of large force consumption, slow speed, poor performance in climbing, etc. in a general bicycle and increases the loading capacity, and therefore, compared with a general bicycle under the same running condition, the utility model saves the labor by more than two times and enhances the vehicle speed by about two times, having the advantages of smooth running, convenient manufacture, repairing and maintenance, long service life and low cost.

Description

Hydraulic transmission bicycle

The utility model relates to a kind of novelty, efficient, labour-saving bicycle, particularly relates to a kind of hydrostatic drive bicycle.

As everyone knows, general bicycle is all formed driver train by foot-operated, chain wheel, chain and flywheel, utilizes the power of pedaling of rider's both legs to make to ride and makes circular movement around dead axle, by mechanical drive wheel is advanced.This pedals power is being the center of circle with the dead axle only, is work done in certain arc length scope on the formed circular trace of radius with foot-operated brachium, and the cooresponding central angle of this section circular arc is about 120 °～140 °, all is in no load movement when riding on other positions.And, the driver train of Regular Bicycle drives to advance with the speed ratio that the torque ratio of 5:1 (ratio of the flywheel radius on promptly foot-operated brachium and the trailing wheel) is finished 1:2.4 usually, when dead axle rotates a week, when finishing a speed ratio driving process, both feet must respectively circle thereupon, obviously, power consumption is bigger, and efficient is lower.In addition, the at present general bicycle speed of a motor vehicle is slower, can only reach 10～15 kilometers/hour; Grade climbing performance is also relatively poor.

The purpose of this utility model is to provide that a kind of climbing is strong, laborsaving, effect is high and speed hydrostatic drive bicycle faster.

The purpose of this utility model is achieved like this: adopt to comprise the interconnective from front to back hydraulic oil pump that is installed on the pedal spindle on the basis of existing bicycle, high-pressure pipeline, the oil motor that oil return pipe and are installed on the mandrel of trailing wheel constitutes driver train.Hydraulic oil pump comprises oil pump housing, well-distributed has a plurality of pistons one oil cylinder group that piston, piston ring, spring and oil cylinder are formed on oil pump housing, order about the swash plate of piston motion, be fixed on the inwall of oil distrbuting box and two sections annular high pressure fuel pipes that communicate with oil outlet at the bottom of the oil cylinder.The one end sealing of two sections annular high pressure fuel pipes, the other end is connected with high-pressure pipeline, and check valve is installed.Inboard at the bottom of each oil cylinder all have one communicate with oil distrbuting box go into oilhole.According to the needs of installing, can and be connected the position that the crossbeam of pedal spindle core and hind axle collides with two beams of oil pump housing and vehicle frame and slot, and avoid oil cylinder.And oil motor comprises stator that is connected with high-pressure pipeline and oil return pipe and the rotor of being made up of spring automatically controlled moving vane.The other end of oil return pipe is connected with the oil distrbuting box of hydraulic oil pump.

Its principle of work is: step under the foot-operated effect at pin, make the swash plate rotation, increase progressively pressure from low to high, piston up-and-down movement and press juice oil under the effect of swash plate, flow out through annular high pressure fuel pipe and from check valve, the high-pressure pipeline of flowing through is constantly delivered to the oil motor blade, and rotor is under the pressure of high pressure liquid oil, just rotate continuously, bicycle is advanced.Hydraulic oil promotes the rotor rotation, when rotor went to for 3/4ths weeks, under the effect of moving vane spring, send the oil distrbuting box of hydraulic oil pump again continuously back to along oil return pipe, like this, make hydraulic oil deliver to oil motor, send hydraulic oil pump back to from oil motor again from hydraulic oil pump, constantly circulation forms direct current hydraulic pressure.

The utility model has following advantage compared to existing technology:

1, the propelling thrust of hydraulic pressure generation is big, rides so need only to pedal gently, and bicycle just can easily advance.

2, speed is fast.F-Zero can reach 25～30 kilometers, doubles for 15 kilometers than the speed per hour of existing ordinary bicycle.

3, grade climbing performance is good.The slope, road of existing highway maximum all sunlight can easily be pedaled up, need not go-cart.

4, long service life.But the major part continuous action is more than 10 years, but piston ring and spring long-term use are more than 2 years.

The utility model is described in further detail below in conjunction with accompanying drawing embodiment:

Fig. 1 is a general illustration of the present utility model.

Fig. 2 is the cutaway view of hydraulic oil pump in the driver train of the present utility model.
