Embodiment
(the first mode of execution)
Fig. 1 is the skeleton drawing of the fluid device 1 of the first mode of execution, and Fig. 2 A is skeleton drawing when whirlpool dish fluid device 11 is worked as decompressor, and Fig. 2 B makes whirlpool coil fluid device 11 as skeleton drawing during compressor operating.
The fluid device 1 of the first mode of execution comprises whirlpool dish fluid device 11, planetary pinion 31, two clutches 41,42 and belt wheel 51 (the first axle).
First, with reference to Fig. 3, whirlpool dish fluid device 11 is summarized.Fig. 3 is the working drawing of whirlpool dish fluid device 11.In figure 3, dish fluid device 11 in whirlpool comprises cylindric housing 12, static vortex disk 13 and movable orbiting scroll 14.
Static vortex disk 13 comprise tabular baseplate part (not shown) and from the baseplate part teeth portion 13a outstanding to movable orbiting scroll 14 side.Movable orbiting scroll 14 also comprise tabular baseplate part (not shown) and from the baseplate part teeth portion 14a outstanding to static vortex disk 13 side.Teeth portion 13a, the 14a of each whirlpool dish 13,14 are formed as in the vortex shape counterclockwise rotated and radius of curvature increases gradually from one end, above-mentioned two teeth portion 13a, the 14a of substantially same size are combined in the mode making swirl direction identical.Now, two teeth portion 13a, 14a, at multiple positions linear contact lay, are formed with confined space (working room) between adjacent two linear contact lay.
Static vortex disk 13 is fixed on cylindric housing 12.Movable orbiting scroll 14 rotates centered by the axle of rotating shaft 21 (with reference to Fig. 1) (the second axle) bias at housing 12 center relative to cylindrical shape.When making movable orbiting scroll 14 rotate towards a direction (being any one in clockwise direction and counter clockwise direction in figure 3), under keeping being fluid-filled the state in the confined space (working room) that is formed between two adjacent linear contact lay portions, make two teeth portion 13a, the linear contact lay position of 14a moves in the same direction gradually.Thus, such as, when making movable orbiting scroll 14 counterclockwise carry out rotating (rotating forward) in Fig. 3, the volume being formed in the confined space between two adjacent linear contact lay increases gradually.On the contrary, when making movable orbiting scroll 14 carry out rotating (reversion) towards clockwise direction in Fig. 3, the confined space be formed between two adjacent linear contact lay portions reduces gradually.
In the leftmost side of Fig. 3, the minimum confined space 15 be formed in the confined space between two adjacent linear contact lay produces at two central parts.If be conceived to this two confined spaces 15, along with movable orbiting scroll 14 rotates forward, can increase gradually to two confined spaces 16,17 as second from the left side of Fig. 3, the 3rd, and the position of confined space 16,17 offsets to periphery.Then, in the rightmost side of Fig. 3, become two maximum confined spaces 18 and produce in outermost perimembranous.In fact, two confined spaces be formed between two adjacent linear contact lay also exist at other position, in other confined space, same change also occur.
On the other hand, change a visual angle, in the rightmost side of Fig. 3, the maximum confined space 18 be formed in the confined space between two adjacent linear contact lay produces two outermost perimembranous.If be conceived to this two confined spaces 18, along with movable orbiting scroll 14 reverses, can reduce gradually to two confined spaces 17,16 as second from the right side of Fig. 3, the 3rd, and position offsets to inner circumferential.Then, in the leftmost side of Fig. 3, become two minimum confined spaces 15 and produce at central part.In fact, two confined spaces be formed between two adjacent linear contact lay also exist at other position, in other confined space, same change also occur.
Utilizing this character produced along with the rotation of movable orbiting scroll 14, whirlpool being made to coil fluid device 11 when rotating forward as decompressor work, when reversing as compressor operating.Movable orbiting scroll 14 has rotating shaft 21.
Coil fluid device 11 in order to make the fluid (refrigeration agent) driven whirlpool dish fluid device 11 from whirlpool flow out or flow into whirlpool dish fluid device 11, housing 12 is provided with the first gateway 22 (with reference to Fig. 1), and this first gateway 22 can make fluid from flowing out in the minimum confined space 15 of two shown in the leftmost side of Fig. 3 or flowing into this confined space 15.In addition, housing 12 is provided with the second gateway 23 (with reference to Fig. 1), and this second gateway 23 can make fluid flow out from the confined space 18 that two shown in the rightmost side of Fig. 3 are maximum or flow into this confined space 18.
When making whirlpool dish fluid device 11 work as decompressor, as shown in Figure 2 A, import the refrigerant gas (fluid) of High Temperature High Pressure from the first gateway 22.The refrigerant gas flowing into the High Temperature High Pressure in confined space 15 from the first gateway 22 is driven (rotating shaft 21 is rotated forward) movable orbiting scroll 14 by the pressure expanded.Refrigeration agent in above-mentioned confined space 15 is along with the expansion (change of state towards right direction with reference to Fig. 3) of this confined space, and lose the power that movable orbiting scroll 14 is driven, arrive soon after most peripheral refrigerant gas as shown in Figure 2 A, be discharged to the outside from the second gateway 23.By importing the refrigerant gas of High Temperature High Pressure continuously from the first gateway 22, with regard to continuing, movable orbiting scroll 14 is driven (rotating shaft 21 continues to rotate forward).Thereby, it is possible to the thermal power transfer had by the refrigerant gas (fluid) of High Temperature High Pressure is for rotating energy (mechanical energy).
On the other hand, when making whirlpool coil fluid device 11 as compressor operating, utilizing the power from outside that the rotating shaft 21 that fluid device 11 is coiled in whirlpool is rotated (reversion), and as shown in Figure 2 B, refrigerant gas being imported from the second gateway 23.The refrigerant gas flow into from the second gateway 23 in confined space 18 is compressed along with the reducing (change of state towards left-hand with reference to Fig. 3) of this confined space, that arrive soon after central part, be in High Temperature High Pressure compared with air refrigerant gas as shown in Figure 2 B, is discharged to the outside from the first gateway 22.Continuing reversion by making the rotating shaft 21 of whirlpool dish fluid device 11 refrigerant gas is imported continuously from the second gateway 23, just can discharge from the first gateway 22 refrigerant gas being in High Temperature High Pressure compared with air continuously.
At this, using when rotating towards a direction as the transformation of energy that fluid is had be mechanical energy rotate decompressor work, carry out pressurizeing and the fluid device of the compressor operating of discharging is defined as " compressor decompressor fluid device " as convection cell when rotating towards other direction.In embodiments, as compressor decompressor fluid device, exemplified with whirlpool dish fluid device 11, but the present invention is not limited to this.Be not limited to whirlpool dish, as long as piston or blade etc. make confined space increase, making fluid device that confined space reduces, that be mainly positive displacement when rotating towards other direction on the contrary when rotating towards a direction, then these equipment are also contained in compressor decompressor fluid device.Thus, also can use these equipment, coil fluid device 11 to replace whirlpool.
In addition, sometimes using when rotating towards a direction as the transformation of energy that fluid is had be mechanical energy rotate motor work, carry out pressurizeing and the fluid device of the pump work of discharging is defined as " pump motor fluid device " as convection cell when rotating towards other direction.If be described according to this definition, then above-mentioned whirlpool dish fluid device 11 is also contained in said pump motor fluid equipment.That is, said pump motor fluid equipment can also be used, to replace compressor decompressor fluid device.
Get back to Fig. 1, when making whirlpool dish fluid device 11 work as decompressor, needing rotating shaft 21 is rotated forward, when making whirlpool coil fluid device 11 as compressor operating, needing rotating shaft 21 is reversed.Therefore, proposing the rotational speed by switching motor generator set, coiling the decompressor work of fluid device as whirlpool and coiling the existing apparatus switched between the compressor operating of fluid device as whirlpool.
But, in existing apparatus, in order to as decompressor work with switch as compressor operating, need to arrange motor generator set, correspondingly can make complex structure.
In addition, in existing apparatus, when making whirlpool dish fluid device work as decompressor, motor generator set is as generator operation.Now, be delivered to motor generator set after the rotation speedup due to whirlpool dish fluid device, therefore, motor generator set (generator) at a high speed (such as 10000rpm) rotates.When motor generator set High Rotation Speed, friction increases, and make the efficiency regenerated reduce by this, the improving amount of fuel efficiency diminishes.
In addition, in existing apparatus, coil basic recovery of the mechanical energy (power) obtained when fluid device works as decompressor using making whirlpool and be accumulated in storage battery as electric power.Thus, when utilizing power to carry out auxiliary to the rotation of motor, utilizing motor generator set to be electric power by the power-converting obtained by whirlpool dish fluid device, the more above-mentioned electric power after conversion is converted to power.That is, by changing, the loss brought is comparatively large, and therefore, the improving amount of the fuel efficiency brought by power-assisted diminishes.In addition, when using motor generator set, needing the circuit that inverter etc. is set, cost is increased, and needs arrange the jumbo storage battery that the electric power after to recovery is accumulated.Consequently, existing apparatus only can be used in the technology in hybrid electric vehicle in reality, and the extensibility of multi-model reduces.
Therefore, the present inventor in consideration whether without motor generator set, just can not coil as whirlpool switch between the decompressor work of fluid device and the compressor operating of coiling fluid device as whirlpool after the invention that completes.That is, the present invention uses planetary gears 31 and two clutches 41,42 as control unit, is switching as between the whirlpool dish decompressor work of fluid device and the compressor operating of coiling fluid device as whirlpool.
In addition, in the present invention, the rotation of motor and auxiliary engine is directly delivered to using making whirlpool coil the mechanical energy (power) of acquisition when fluid device 11 works as decompressor.That is, between belt wheel 51 and the crankshaft belt wheel 54 of motor 53, hang strip winding 55, thus form band conducting unit, the crankshaft synchronous rotary of belt wheel 51 and motor.In addition, the present invention is not limited to the belt driver be made up of belt wheel, also can be applied in the transmission device and gear drive using chain.
Planetary gears 31 comprises sun gear 32, ring gear 33, multiple planetary pinion 34 and planetary carrier 35, wherein, these planetary pinions 34 engage with sun gear 32 and ring gear 33 simultaneously and around sun gear 32 around, the axle of above-mentioned planetary carrier 35 to these planetary pinions 34 is fixed.
The rotating shaft 52 of belt wheel 51 is connected with the axle of ring gear 33, the rotating shaft 21 that fluid device 11 is coiled in whirlpool is connected with the axle of sun gear 32.Between planetary carrier 35 with ring gear 33, be provided with the first clutch 41 that these two elements are connected, are discharged, in addition, between planetary carrier 35 with shell 36, be provided with the second clutch 42 that these two elements are connected, are discharged.The configuration of first clutch 41 is not limited in this.First clutch 41 ' (dotted line with reference to Fig. 1) such as also can be set between planetary carrier 35 and sun gear 32.
Why the rotational speed that fluid device 11 is coiled in whirlpool under the combination of the connection of two clutches 41,42, release and use is worth the chart carrying out gathering when the rotational speed of belt wheel 52 is 1000rpm by Fig. 4.Fig. 5 A ~ Fig. 5 C is the speed line chart of the work representing planetary gears 31.Fig. 6 A ~ Fig. 6 C is the figure of the action of each element of the planetary gears 31 correspondingly representing reality with Fig. 5 A ~ Fig. 5 C.
In addition, in Fig. 4, Fig. 5 A ~ Fig. 5 C, Fig. 6 A ~ Fig. 6 C, ring gear 33 and the ratio of the number of teeth of sun gear 32 are set as 2:1.Such setting ring gear 33 is based on following reason with the ratio of the number of teeth of sun gear 32.That is, to making whirlpool dish fluid device 11 as refrigerant volume flow required value when decompressor work and making whirlpool dish fluid device 11 study as refrigerant volume flow required value when compressor operating, find that the ratio of required value is 1:2.By this, when make whirlpool coil fluid device 11 as compressor operating, with make whirlpool coil fluid device 11 as decompressor work situation compared with, need the rotational speed of 2 times.In addition, in general, also the known whirlpool dish fluid device 11 that makes is more as refrigerant volume flow required value when decompressor work than making whirlpool coil fluid device 11 as refrigerant volume flow required value when compressor operating.
First clutch 41 is discharging and speed line chart under the state connected by second clutch 42 by Fig. 5 A.In this state, the power of motor 53 is utilized to drive belt wheel 51.Make planetary carrier 35 be connected with shell 36 (with reference to Fig. 2 A) owing to utilizing the connection of second clutch 42, therefore, the rotating speed of planetary carrier 35 becomes zero [rpm].For convenience of description, belt wheel 51 is made synchronously to rotate with 1000 [rpm] with the rotation of motor.Now, the rotating speed of sun gear 32 increases according to reduction speed ratio, Cheng Wei – 2000 [rpm].The front negative symbol of 2000 [rpm] represents that sun gear 33 reverses relative to belt wheel 51.
First clutch 41 is connecting and speed line chart under the state discharged by second clutch 42 by Fig. 5 B.In addition, in order to compare with Fig. 5 A, the rotational speed of belt wheel 51 is made to be 1000 [rpm].Make planetary carrier 35 be connected with ring gear 33 (with reference to Fig. 2 B) owing to utilizing the connection of first clutch 41, therefore, ring gear 33 and planetary carrier 35 are also in identical rotational speed (1000rpm).Thus, the rotational speed of sun gear 32 is also identical rotational speed (1000rpm).In other words, the rotating shaft 21 of whirlpool dish fluid device 11 is the state directly linked with belt wheel 51.
Fig. 5 C is the speed line chart under the state discharged by two clutches 41,42.In addition, in order to compare with Fig. 5 A and Fig. 5 B, the rotational speed of belt wheel 51 is made to be 1000 [rpm].In this condition, can eliminate belt wheel 51 and whirlpool coil fluid device 11 rotating shaft 21 between the transmission of moment of torsion.In addition, the rotating speed due to sun gear 33 is zero [rpm], and therefore, planetary carrier 35 rotates with the rotational speed at the line linked by 1000 [rpm] of this point and the belt wheel 51 point place consistent with the vertical line of planetary carrier 35.
In fig. 5, belt wheel 51 is positioned at driving side, but in figure 5b, whirlpool dish fluid device 11 is in driving side.That is, according to Fig. 5 B, when making whirlpool dish fluid device 11 make rotating shaft 21 rotate forward with 1000 [rpm] as decompressor work, belt wheel 51 can be made to rotate forward with 1000 identical [rpm].Like this, utilizing whirlpool to coil fluid device 11 by the transformation of energy of fluid is rotation energy, the above-mentioned rotation after conversion can be used for the rotation of auxiliary engine 53.On the other hand, according to Fig. 5 A, when utilizing the driving of motor 53 to make belt wheel 51 rotate forward with 1000 [rpm], rotating shaft 21 can be made to reverse with 2000 [rpm], that is, whirlpool can be coiled fluid device 11 and being used as compressor.
As mentioned above, in the present embodiment, ring gear 33 and the gear ratio of sun gear 32 are set as 2 times, but the present invention is not limited to this situation, the gear ratio of ring gear 33 and sun gear 32 can be set between 1.5 times to 4 times.Below, be explained.
In the car being mounted with motor, car (or the air displacement of the motor loaded) larger situation and car (or the air displacement of the motor loaded) less situation are compared.If the number of passenger is identical, because required air conditioning capacity is substantially constant, therefore, compared with when the refrigerant flow required value of compressor when car is larger is less with car, substantially do not change, in contrast, Che Yue great, waste heat is larger, therefore, when wanting to increase waste heat recovery amount further, the refrigerant flow required value of decompressor when car is larger is larger compared with the refrigerant flow required value of decompressor time little than car.Suppose that the rotational speed of compressor when car is larger does not need such height, therefore, relatively reduces gear ratio when more stool increases compressor decompressor fluid device (specification) to car.On the other hand, the rotational speed needs of compressor when car is less are set as higher, therefore, relatively increase gear ratio.In addition, in the scope of practicability, when considering the air displacement of loading motor of size, i.e. practicability and the specification of compressor decompressor fluid device of car, after studying the scope of gear ratio, known 1.5 times is suitable to 4 times.
