Hot working fluid is sent into expanding machine 1 and does work, and clutch 4 is closed driving vehicle.Automobile stops for a long time, hot working fluid in working medium buffer tank 13
Gradually after cooling, the secondary rotating forward of working medium pump 12 makes to restPose full of cold working medium in working medium cache slot；
Electromagnetism exhaust gas triple valve 20 changes high-temp waste gas 21 from into exhaust gas when plant failure or special circumstances are not required to operation
The state of hot device 9 switches to exhaust pipe 22 and discharges, and described device is stopped transport；
As shown in Fig. 2, because automobile travels forward, wind enters condenser 6 and passes sequentially through the condenser pipe that cross section is water-drop-shaped
23 make working substance steam be condensed into liquid with intraductal working medium steam heat-exchanging, from 25 outflow of liquid refrigerant outlet, into working medium storage tank 7.
When automobile driving speed reaches definite value less than temperature in definite value or condenser and atmosphere temperature-difference, vehicle-mounted control computer then starts roof condensation
The auxiliary blower 24 and closing condenser electromagnetism shutter 26 of device realize forced ventilation cooling, when wind speed and the condensation temperature difference meet rule
Fixed, vehicle-mounted control computer then stops condenser auxiliary blower 24 and opens condenser electromagnetism shutter 26, is divulged information using running car
Cooling；
As shown in figure 3, the structure diagram for contiuously variable transmission 3, wherein holddown spring 32 will be actively by bearing group 30
29 driven shaft taper cone pulley group 37 of axis taper cone pulley group and 39 pre-pressing of variable transmission belt active splined shaft 28 and contiuously variable transmission from
On dynamic splined shaft 34, effective transmission combination is formed.Wherein, the left side taper cone pulley of driving shaft taper cone pulley group 29 and contiuously variable transmission master
Dynamic splined shaft 28 is rigidly connected, and right side taper cone pulley is coupled with active splined shaft 28 by spline but left and right is allowed to move axially, from
The right side taper cone pulley of moving axis taper cone pulley group 37 is rigidly connected with contiuously variable transmission driven spline shaft 34, and left side taper cone pulley passes through flower
Key connect with driven spline shaft 34 but left and right is allowed to move axially, which is synchronized by worm and gear
Axis 42 ensures that 39 center of variable transmission belt is always perpendicular to each wheel group axis during speed governing.Mechanical energy process is transmitted in entire combination rotation
In, when the temperature of the working medium of 1 entrance of expanding machine becomes larger higher than required range expansion ratio, the expanding machine inside and outside differential pressure can be high
In required range, vehicle-mounted control computer then starts contiuously variable transmission servo motor 41 and is adjusted actively by worm and gear synchronizing shaft 42
Axis worm and gear actuator 31 and driven shaft worm and gear actuator 36 respectively synchronous driving shaft perform screw rod 33 synchronize release
It puts driven shaft and performs screw rod 35, driving shaft taper cone pulley group 29 is made to tend to open, variable transmission belt 39 is in the wheel to upper movement circumference
Diameter becomes smaller, and synchronizing makes driven shaft taper cone pulley group 37 tend to be closed, and variable transmission belt 39 becomes upper movement circle diameter in the wheel
Greatly, 1 rotating speed of expanding machine is improved, and so as to increase working medium flow, makes to be down to required model at a temperature of expander inlet working medium
In enclosing, however the expansion ratio of working medium is also dropped in required range, and described device output power increases, and efficiency of expander keeps good
It is good.When the temperature of expander inlet working medium is less than required range, then regulative mode is on the contrary, system output power trend subtracts
Few, efficiency of expander continues to keep good.
If the device needs more accurately to adjust 1 expansion ratio of expanding machine, the adjustable expanded machine of expansion ratio can be used,
Vehicle-mounted control computer turns down expander inlet slide-valve by actuator or subtracts when 1 inside and outside differential pressure of expanding machine is higher than required range
Few air chamber volume keeps expanding machine inside and outside differential pressure within required range to expand expansion ratio.Expanding machine inside and outside differential pressure is less than
During required range, then it is opposite to adjust direction.Even if but during adjustable expanded using the expansion ratio machine of the device, still with stepless
Speed changer 3 is main regulative mode.
As the structure of clutch, as shown in figure 4, clutch driving shaft 50 and 3 driven shaft output gear of contiuously variable transmission
38 connections, and be rigidly connected with active friction pair 51.It is connect from dynamic friction pair 49 by bearing block 48 with 46 spline of driven shaft, from
Clutch double speed servo motor 44 is connect with buffer spring actuator connection rod set 43 by bearing block 48 with from dynamic friction pair 49, and
It small range can be moved axially on driven shaft 46.The connecting rod spherical support 52 of connection rod set is fixed on casing.
During automobile normal running, active friction pair 51 from dynamic friction pair 49 with being closed, the mechanical energy of contiuously variable transmission 3
Pass through 4 auxiliary drive automobile of clutch.When automobile brake, dynamics and braking acceleration vehicle-mounted control are trampled according to brake pedal
Launch computer double speed servo motor 44 disengages active friction pair 51 and from dynamic friction pair 49, so as to stop auxiliary drive automobile.With
Upper two condition need to only meet an i.e. actionable clutch.Vehicle restores above when driving and acts on the contrary, mechanical energy restores driving
Automobile.The clutch 4, the pair that rubs after system-down belong to disengaged position.
In Fig. 5, when shaft coupling 2 uses, input shaft 62 is fixed on bearing block flange 64 and is installed by bearing
There is input shaft permanent magnet 68, output shaft permanent magnet 70 is installed in 63 sleeve of output shaft.There is isolation cover 69 to prevent between two permanent magnets
Only refrigerant leakage.Generating winding 65 is installed close to 64 side of bearing block flange.When input shaft 62, which is inflated machine 1, to be driven, input shaft
Permanent magnet 68 rotates, because flux interaction drives 63 synchronous rotary of output shaft to transmit mechanical energy.And generating winding 65 in input shaft forever
Electric current is induced in 68 rotating excitation field of magnet, by supplying main working medium pump 8, secondary working medium pump after 66 burning voltage rectification of variable voltage rectifier
12nd, servo motor, vehicle-mounted computer, extra electricity may be incorporated into vehicle power supply.
High-temp waste gas thermal energy is partially converted into mechanical energy auxiliary drive automobile and generates small part electric energy by the utility model
