With means, various replacements and change are made, should all include within the scope of the present invention.
Embodiment 1:
A kind of hydraulic bicycle being suitble to more hillside fields shapes, bicycle main part include the foot being mounted on cycle frame
Pedal 11, handlebar 12, ratchet mechanism 13, bicycle rear 14, seat 15.
Wherein, the mounting means of handlebar 12, front wheel and seat 15 is identical as foot-operated ordinary bicycle.Seat 15
The rod piece of lower section is activity installation.Pedal 11 does not drive bicycle rear 14 using chain drive, after bicycle
Hydraulic motor 7 of the wheel 14 by being mounted on vehicle frame drives.Hydraulic pump 1 is mounted on cycle frame.The shaft of the hydraulic pump 1
Through hydraulic pump two sides.Pedal 11 described in two is mounted on the shaft two of hydraulic pump 1 by the ratchet mechanism 13 of single-direction transmission
End.Pedal 11 is merely able to that shaft is driven to rotate to a direction.
Referring to Fig. 1, the oil outlet of hydraulic pump 1 is separately connected the A mouth of check valve I2, the A of two position two-way valve I4 by pipeline
Mouth, two-position four-way are servo-actuated the B mouth of the P mouth of reversal valve 6, check valve II10.
The B mouth of check valve I2 passes through the P of the hydraulic fluid port of piping connection accumulator 3, the A mouth of two position two-way valve I4, overflow valve 5
Mouthful.In embodiment, preferably gasbag-type converts into shape accumulator.This accumulator has inertia small, is quick on the draw compact-sized, size
Small, light-weight, easy for installation feature.Convertible is suitable for accumulation of energy, corrugated to be suitable for Absorbing hydraulic pulsation.Its operating pressure
For 3.5~35MPa, range of capacity is 0.16~35L, and temperature range is -10~65 DEG C.
The T mouth of overflow valve 5 passes through the P mouth of piping connection fuel tank 9 and two position two-way valve I4.
Two-position four-way is servo-actuated A mouth of reversal valve 6 and is separately connected the oil inlet of hydraulic motor 7 and fuel-displaced by pipeline with B mouthfuls
Mouthful；
The T mouth that two-position four-way is servo-actuated reversal valve 6 passes through the A mouth of piping connection check valve II10, the P of two position two-way valve II8
Mouthful, the inlet port of hydraulic pump 1；
The A mouth of two position two-way valve II8 passes through piping connection fuel tank 9；
Embodiment 2:
The primary structure of the present embodiment is with embodiment 1, further, referring to fig. 2, check valve I2, check valve II10 etc. are hydraulic
Element is arranged on front side of bicycle on vehicle frame.Two position two-way valve I4 and two-position four-way are servo-actuated reversal valve 6 and are arranged on handlebar, can be with
By manually adjusting；Accumulator 3 is arranged on the vehicle frame below handlebar.Overflow valve 5 is arranged on the vehicle frame on rear side of bicycle.
It is worth noting that the bicycle has two kinds of driving status of normally travel and accumulation of energy according to hydraulic principle Fig. 1,
Fuel tank 9 has drip-preventing function and hydraulic braking function simultaneously.
One, when normal riding condition:
Two position two-way valve I4 is manually adjusted to left position.
It manually adjusts two-position four-way and is servo-actuated reversal valve 6 to any position, hydraulic oil flows to T from P mouthfuls when meeting normally travel
Mouthful.
Press oil port of the hydraulic oil through hydraulic pump 1 is servo-actuated reversal valve 6 by two-position four-way, drives hydraulic motor 7, Zhi Houyou
It is servo-actuated reversal valve 6 by two-position four-way, flows back to fuel tank 9.
Two, energy accumulating state (when being in descending):
Two position two-way valve I4 is manually adjusted to right position.
It manually adjusts two-position four-way and is servo-actuated reversal valve 6 to the position opposite with normally travel, hydraulic oil is made to flow to P from T mouthfuls
Mouthful.
At this point, hydraulic motor 7 is servo-actuated reversal valve 6, check valve by two-position four-way essentially as hydraulic pump, by hydraulic oil
I2 is pumped into accumulator 3, is recycled to energy.When hypertonia in accumulator 3, hydraulic oil passes through overflow valve 5 again and flows back to
Fuel tank.Since hydraulic motor 7 is used as power source here, and hydraulic motor 7 is rigidly connected with bicycle rear axle, therefore can play liquid
The dynamic effect of compacting.
Embodiment 3:
The primary structure of the present embodiment with embodiment 2, further,
Two position two-way valve II8 is arranged on the spring return type two position two-way valve of 15 lower section of seat.When people is in seat 15
When upper, under the pressure effect of people, two position two-way valve II8 is opened, and fuel tank 9 is connected with atmosphere, while accessing oil circuit.When people leaves
When seat, two position two-way valve II8 is closed under action of reset spring, and fuel tank 9 is neither connected with atmosphere, does not also access oil circuit.
The two position two-way valve II8 of this system is repairing element, to increase the experience comfort level travelled.This system is with atmosphere
The repairing power being used as power solves closed circuit internal cause and generates vacuum degree, destroys uncomfortable brought by the continuity of fluid
" de- chain " is felt.When people is sitting in seat 15, human body weight keeps two position two-way valve 5 in the open state, fuel tank 9 simultaneously with it is big
Gas is connected with oil circuit, if fruit vacuum instantaneously occurs in oil pipe at this time, the oil in fuel tank 9 can be entered by two position two-way valve II8
In oil circuit.When people leaves seat 15, two position two-way valve 5 is automatically closed under the action of reset spring, fuel tank 9 not with atmosphere or
Oil circuit is connected, and can prevent people when leaving bicycle because of hydraulic fluid leak caused by a variety of causes.
Pedal 11 and quantitative hydraulic pump 1 are connect by ratchet 13, when pedal cannot provide power, hydraulic pump 1 no longer with
It is rotated with pedal 11.Hydraulic oil flows through check valve 8 at this time, two-position four-way is servo-actuated reversal valve 6, hydraulic motor 7 constitutes circuit, can subtract
Small energy consumption.
Embodiment 4:
The primary structure of the present embodiment is with embodiment 2, further, carries out type selecting to performance parameter and element, is as follows:
1. the selection of motor and pump: in general flat country, maximum resistance torque about Tm=80Nm, according to Tm=pVm,
Motor displacement selects Vm=10ml/r, p=8MPa, according to speed ratio(speed ratio can according to their own needs into
Row is selected, and default is 1), therefore to select discharge capacity Vp for the gear pump of 10ml/r herein
2. the torque capacity that cyclist can export is about are as follows: torque=power × torque arm length.
Assuming that 1: cyclist scrunches crank and the strength of weight has been used to assume 2: this person's weight M；Assuming that 3: the crank choosing of this vehicle
It is longest to select specification, length L is 177.5 millimeters.Then: the torque under above-mentioned assumed condition are as follows: T=MgL.People is allowed to feel comfortable
Torque is 10~50N.m.According toAcquire hydraulic circuit pressure within the scope of this.
3. the selection of accumulator:
Variable declaration: p2For maximum pressure, p1For minimum pressure, p0For the blowing pressure；The capacity of accumulator is V0；Release
Oil mass be Δ V=V2-V1
The course of work of actually accumulator belongs to polytropic process, and when oil storage, gas compression is constant temperature process, gas when draining the oil
Body is expanded to adiabatic process, and polytropic exponent is generally located on 1.25.
According to the equation of gas state:To acquire accumulator volume:Wherein p0About 0.8p2Using accumulator release energy bicycle automatic running distance be s:(about 40cm) can reach traveling when releasing energy by adjusting the pressure in circuit and the volume of accumulator
Distance requirement.
4. the relationship of the gradient and torque: people car weight amount M can obtain relationship formula according to stress balance:For accumulator maximum pressure thus energy on the gradient:Wherein D is that wheel is straight
Diameter (about 40cm).
The maximum gradient in the case where releasing energy without using accumulator on energy are as follows: 。
