Shown in 3, each cam position is at least distributed two cams on a circumference, and drive cam shaft rotates a circle, and its corresponding
The piston of one hydraulic cylinder 2 is at least moved back and forth twice.Can also be connected in other embodiment by slider-crank mechanism
The piston of one hydraulic cylinder 2, circular motion is converted into the straight reciprocating motion of the piston of first hydraulic cylinder 2.
2 pairs of courses of work of the invention are illustrated below in conjunction with the accompanying drawings：
Six crank-shaft link necks 601 be along the circumferential numbering of maneton 6 " one, two, three, four, five, six ", by " one " and
" six ", " two " and " three ", " five " and " four " one group totally three groups two-by-two, the cross-section center point of every group of two connecting rod necks 601 with it is bent
The angle of the cross-section center point line of axle journal 6 is 180 °.I.e. the center at the center of " two " and " three " and maneton 6 is in same straight line
On.
For the ease of describing the piston abbreviation " big piston " of second hydraulic cylinder 3, piston referred to as " the small work of first hydraulic cylinder 2
Plug ".Six first hydraulic cylinders 2 are each attached on body base and in " one " word arrangement, public fuel reserve tank 5 and six the second hydraulic pressure
Cylinder 3 is also secured on body base, and six of which second hydraulic cylinder 3 in public fuel reserve tank 5, is corresponded to respectively in " one " word arrangement
Six first hydraulic cylinders 2, six second hydraulic cylinders 3 are connected with public fuel reserve tank 5 and six first hydraulic cylinders 2 respectively.It is six big
Top land sets crankshaft-link rod connecting pin, for installing crankshaft-link rod.
The valve piston of six first hydraulic cylinders 2 is under the driving of drive cam shaft, by the hydraulic pressure oil in public fuel reserve tank 5
Corresponding six second hydraulic cylinders 3 are not inputted, alternately promote the big piston in second hydraulic cylinder 3 to be transported from lower dead center to top dead centre
OK, so as to promote crank-shaft link neck 601 to be run from minimum point to peak by crankshaft-link rod 7.
When crank-shaft link neck 601 " one " rotation is to minimum point, crank-shaft link neck 601 " six " rotation to peak；Work as song
When axle connecting rod neck 601 " two " rotation is to minimum point, crank-shaft link neck 601 " three " rotation to peak；When crank-shaft link neck 601
When " five " rotation is to minimum point, Crankshaft connecting rod neck 601 " four " rotation to peak；Conversely, when crank-shaft link neck 601 " six ",
When " three ", " four " are rotated to minimum point respectively, " one " " two ", " five " rotate to peak respectively.
When crank-shaft link neck 601 " one " rotation is to minimum point, the timing belt pulley on bent axle time output shaft end drives
Bossing on timing belt pulley on fuel outlet valve camshaft 4, and then drive fuel outlet valve camshaft 4 synchronously arrives at fuel outlet valve and opened
Close 303 positions and the jacking fuel outlet valve of threshold switch 303 that will drain the oil, close fuel outlet valve, corresponding with crank-shaft link neck 601 " one " first
Hydraulic oil in public fuel reserve tank 5 is inputted second hydraulic cylinder 3 corresponding with " one ", second hydraulic cylinder 3 by the valve piston of hydraulic cylinder 2
In big piston and crankshaft-link rod 7 promote crank-shaft link neck 601 " one " rotated from minimum point to peak；At the same time, it is in
Recess on the corresponding fuel outlet valve camshaft 4 of crank-shaft link neck 601 " six " of peak position synchronously arrives at fuel outlet valve and opened
303 positions are closed, the spring drained the oil on threshold switch will be switched and ejected from oil discharging valve, and fuel outlet valve is opened, in second hydraulic cylinder 3
Hydraulic oil is back to public fuel reserve tank 5 in the presence of " one " up promotes, and crank-shaft link neck 601 " six " is from peak toward minimum
Point revolution.
Crank-shaft link neck 601 " two " and " three ", " five " and " four " are respectively in the way of foregoing " one " and " six ", cycle alternation
Promote crank-shaft link neck 601 to rotate, and pass through the external output mechanical energy of bent axle.
By being further equipped with battery in this example, battery is connected to startup motor and generator, and battery is by generator
Electrical power storage, and provide power supply to start motor.

For 60 °, crank-shaft link neck 601 " three " is also at up pushing direction, and the angle from " one " is 120 °, apart from peak " six "
Angle is 60 °, at this moment, there is crank-shaft link neck 601 " three " and " four " two upwards thrusts；When crank-shaft link neck 601 " one " is upward
Promotion leaves minimum point, and not up to 60 ° angles, crank-shaft link neck 601 " three " does not reach peak also, now, have " three ", " four ",
The upward thrust of " one " three crank-shaft link necks 601；When crank-shaft link neck 601 " three " reaches peak, crank-shaft link neck 601
" two " reach minimum point, there is crank-shaft link neck 601 " four " and " one " two upwards thrusts, such cycle alternation.So, bent axle connects
The upwards thrust of bar neck 601 is changed between two and three all the time, and correspondence work torque is calculated as by two thrusts：2T*2=
4T。
2T*2*9.8=39200N*m, speed of crankshaft is designed by 15r/min, output torque 39200N*m.By speed of crankshaft
15r/min, moment of torsion 39200N*m are by making clutch wheel rotating speed 3800r/min, moment of torsion 153N*m after booster engine speedup.
After generator is by speed pulley speed change, with rare-earth permanent-magnet AC generator rotational speed matches.The present embodiment liquid
Pressure power drive unit system is arranged on orthodox car engine position, bent axle main output shaft end connection booster engine, booster engine output
Clutch wheel connection automobile clutch on axle.The present embodiment starts knob (or car key) and is arranged on the orthodox car steering wheel right side
At the car key hole of lower section.Instrument is arranged at orthodox car instrument board, and is set according to the need for hydraulic power drive unit system
Put corresponding instrument.The present embodiment removes the gas pedal of orthodox car, and design uses clutch pedal and brake pedal.This reality
Apply example and be designed with emergency power off brake gear, promptly touch on the brake pedal on earth, by the timely confession for blocking generator to motor
Electricity, stops the operation of hydraulic power drive unit system, meanwhile, brake block holds brake disc tightly, stops the automobile in traveling.And lead to
Control system is crossed, generator is controlled to the charging of battery and stops filling；The startup, speed governing and stopping for starting motor are controlled
System；The voltage of motor, rotating speed, operation and stopping are controlled.The hydraulic power drive unit system of the present invention is low
Rotating speed, high pulling torque and at the uniform velocity operate, increased speed with booster engine, in driving running car, pass through gearbox reduction or lifted
Travel speed.
Any person skilled in the art can all be carried out under the spirit and scope without prejudice to the present invention to above-described embodiment
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from disclosed spirit with
All equivalent modifications completed under technological thought or change, should be covered by the claim of the present invention.
