Specific implementation mode
With reference to embodiment, the invention will be further described, but should not be construed the above-mentioned subject area of the present invention only
It is limited to following embodiments.Without departing from the idea case in the present invention described above, according to ordinary skill knowledge and used
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 that activity is installed.Pedal 11 does not drive bicycle rear 14 using chain drive, after bicycle
Wheel 14 is driven by the hydraulic motor 7 on vehicle frame.Hydraulic pump 1 is mounted on cycle frame.The shaft of the hydraulic pump 1
Through hydraulic pump both 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 by pipeline be separately connected the A mouths of check valve 2, the A mouths of two position two-way valve 4,
Two-position four-way is servo-actuated the B mouths of the P mouths of reversal valve 6, check valve 10.
The B mouths of check valve I2 pass through the hydraulic fluid port of piping connection accumulator 3, the P mouths of the A mouths of two position two-way valve 4, overflow valve 5.
In embodiment, preferably gasbag-type converts into shape accumulator.This accumulator has inertia small, is quick on the draw compact-sized, and size is 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 is
3.5~35MPa, range of capacity are 0.16~35L, and temperature range is -10~65 DEG C.
The T mouths of overflow valve 5 pass through the P of piping connection fuel tank 9 and two position two-way valve 4 mouths.
Two-position four-way is servo-actuated A mouths 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 mouths that two-position four-way is servo-actuated reversal valve 6 pass through the A mouths of piping connection check valve 10, the P mouths of two position two-way valve 8, liquid
The inlet port of press pump 1;
The A mouths of two position two-way valve 8 pass through piping connection fuel tank 9;
Embodiment 2:
The primary structure of the present embodiment is with embodiment 1, further:Referring to Fig. 2, the Hydraulic Elements such as check valve 2, check valve 10
It is arranged on front side of bicycle on vehicle frame.Two position two-way valve 4 and two-position four-way servo valve 6 are arranged on handlebar, can be by manual
It adjusts;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 according to hydraulic principle Fig. 1, which has two kinds of transport conditions of normally travel and accumulation of energy,
Fuel tank 9 has drip-preventing function and hydraulic braking function simultaneously.
One, when normal riding condition:
Two position two-way valve 4 is adjusted manually to left position.
Two-position four-way is adjusted manually and is servo-actuated reversal valve 6 to any position, and 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 in descending):
Two position two-way valve 4 is adjusted manually to right position.
Two-position four-way is adjusted manually and is servo-actuated reversal valve 6 to the position opposite with normally travel, and 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 essentially as hydraulic pump, by hydraulic oil by two-position four-way
2 are pumped into accumulator 3, are recycled to energy.When hypertonia in accumulator 3, hydraulic oil flows back to oil by overflow valve 5 again
Case.Since hydraulic motor 7 is used as power source here, and hydraulic motor 7 is rigidly connected with bicycle rear axle, therefore can play hydraulic pressure
The effect of braking.
Embodiment 3:
The primary structure of the present embodiment is with embodiment 2, further:
Two position two-way valve 8 is arranged on the spring return type two position two-way valve of 15 lower section of seat.When people is on seat 15
When, under the pressure effect of people, two position two-way valve 8 is opened, and fuel tank 9 is connected with air, while accessing oil circuit.When people leaves seat
When, two position two-way valve 8 is closed under action of reset spring, and fuel tank 9 is neither connected with air, and oil circuit is not also accessed.
The two position two-way valve 8 of this system is repairing element, to increase the experience comfort level travelled.This system is made with air
The repairing power of power solves closed circuit internal cause and generates vacuum degree, destroys uncomfortable caused by the continuity of fluid " de-
Chain " is felt.When people is sitting in seat 15, human body weight makes two position two-way valve 5 be in open state, fuel tank 9 simultaneously with air and
Oil circuit is connected, 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 8 in oil circuit.
When people leaves seat 15, two position two-way valve 5 is automatically closed under the action of resetting spring, and fuel tank 9 does not connect with air or oil circuit
It is logical, when can prevent people from leaving bicycle caused by a variety of causes hydraulic fluid leak.
Pedal 11 is connect with quantitative hydraulic pump 1 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, two-position four-way servo valve 6, hydraulic motor 7 and constitutes circuit at this time, can reduce energy
Amount consumption.
Embodiment 4:
The primary structure of the present embodiment is with embodiment 2, further, type selecting, such as following table is carried out to performance parameter and element:
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 the demand of oneself into
Row is selected, and acquiescence 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: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 of this vehicle selects
It is longest to select specification, length L is 177.5 millimeters.Then:Torque under above-mentioned assumed condition is: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 0.8p2
Using accumulator release energy bicycle automatic running distance be s:(about 40cm) can pass through
The volume of the pressure and accumulator that adjust circuit reaches the distance requirement travelled when releasing energy.
4. the relationship of the gradient and torque:People car weight amount M, relationship formula can be obtained according to stress balance:
For the maximum pressure of accumulator
Therefore the gradient on energy:Wherein D is wheel diameter (about 40cm).
The maximum gradient in the case where releasing energy without using accumulator on energy is:
