Embodiment
Embodiment 1:
Elaborate according to Fig. 1 to the 3 pair of first embodiment of the present invention.As illustrated before, the present invention has been described in the example of the rotary piston engine of the rotary piston with the shape that is generally triangular.
In the shell 10 of rotary-piston machine, accommodate the rotary piston 12 with center hole 16.Between the circumference with the rotary piston 12 of the nemaline inwall of outer shaft and triangle of shell 10, be configured with three working rooms 14.In three working rooms 14, four working strokes of rotary piston engine are carried out in known manner, rotate rotary piston.
As shown in Figure 1, the center hole 16 of rotary piston 12 is formed with internal messing tooth 18.The internal messing tooth 18 of rotary piston 12 is meshed with gear 20, and gear 20 torsionally (drehfest) is arranged on shell 10.In shell 10, the motion of rotary piston 12 is controlled by 18 and 20 these two engagements.
In addition, in shell 10, be provided with eccentric shaft 22 further, it is oriented to fixing gear 20 coaxial.Rotary piston 12 operates round eccentric shaft 22 in engine housing 10, and wherein rotary piston 12 is positioned in the eccentric part 24 of eccentric shaft 22.
Eccentric shaft 22 and motor power transducer (not shown) are coupled, and form power generating equipment.This motor power transducer is such as generator, it converts the mechanical rotational energy of eccentric shaft 22 to electric energy in rotary-piston machine work, then being such as stored in (not shown) in electrochemical energy storage device, such as, is battery pack or storage battery or analog.
Then can with the energy stored in this energy storing device such as service meter, this motor can at least one wheel of driving machine motor-car.The power generating equipment with such rotary piston engine and generator uses as so-called distance increasing unit in this case, and it can charge to electric drive motor-car when needed again, thus increases the stroke of Motor Vehicle.
In addition, on three angles of rotary piston 12, also there is sealing gasket 26 in FIG, be used for three working rooms 14 to be isolated from each other.
As shown in Figure 2 A and 2B, in order to carry out subregion to the working room 14 of rotary piston engine, two side dividing plates or side glass 28,30 are set in the axial direction.
Equally, as shown in Figure 2 A and 2B, between the center hole 16 and working room 14 of rotary piston 12, there is sealing medium 32.Sealing medium 32 is expressed as scraper plate ring (Kratzring), is arranged on side glass 28,30 and/or rotary piston 12 side.
What Fig. 2 A and 3A showed is the rotary piston engine of the first operating mode, and wherein rotary piston 12 is in minimum position.What Fig. 2 B and 3B showed is the rotary piston engine of the second operating mode, and wherein rotary piston 12 is in the highest position.
As shown in Figures 2 and 3, in the center hole 16 of rotary piston 12, form volume space 34, it is connected with circulator oil phase, is supplied to lubricant oil at rotary piston engine duration of work by means of oil pump.This lubricant oil is used as the lubrication of the axle journal of rotary piston 12 on eccentric shaft 22.
Volume space 34 for holding lubricant oil is surrounded by rotary piston 12 self and scraper plate ring 32 substantially.In the normal operation of rotary-piston machine, lubricant oil is drawn through this volume space, the through hole 40 in such as side glass 28,30, and wherein eccentric shaft 22 is by the through hole on this side glass.Therefore through hole 40 determines the maximum packed height 36 of the lubricant oil in the volume space 34 of rotary piston 12.
In the operating mode shown in Fig. 2 A and 3A, rotary piston 12 is in the minimum pivotal position in shell 10, and the maximum packed height 36 of above-mentioned volume space 34 is now maximum.In the second operating mode shown in Fig. 2 B and 3B, rotary piston 12 is in the highest pivotal position in shell 10, and the maximum packed height 36 of above-mentioned volume space 34 is now minimum on the contrary.
Owing to there is such danger in the longer down period situation especially after rotary piston engine is closed; although namely there is sealing medium 32; still lubricant oil is had from volume space 34 to seepage working room 14; and can burn there when rotary piston engine starts again, therefore need default special control gear to control the running of rotary piston engine.This control gear controls rotary piston engine, and (and after the oil pump closedown in same lubrication oil circulation loop) rotary piston 12 after rotary piston engine is closed is on the pivotal position shown in Fig. 2 B and 3B or at least close with shown pivotal position pivotal position as much as possible.
In order to reach this purpose, mention different control programs, it can be replaced or combinationally use:
-rotary piston 12 braked after rotary-piston machine is closed on the final pivotal position expected or brake on the region, final pivotal position expected;
-after rotary-piston machine is closed, reduce the rotating speed of rotary piston 12 until state of rest according to speed curves given in advance;
-after rotary-piston machine is closed, measure the pivotal position of rotary piston and be rotated further according to the pivotal position measured in the conceived case, until on the final pivotal position being in expectation or be on the region, final pivotal position of expectation.
In order to determine the pivotal position of rotary piston 12, such as can preset measuring device, measuring device can adopt the form of sensor or rotating coder, and it is directly recorded the pivotal position of rotary piston 12 or is indirectly obtained the pivotal position of rotary piston by the pivotal position of such as eccentric shaft 22.
Except above-mentioned when rotary-piston machine is closed controllability, also tool has the following advantages, namely can rotary-piston machine close after in other words rotary piston 12 stop after being rotated further eccentric shaft 22.By the rotation of eccentric shaft 22, can continue to transmit a certain amount of lubricant oil outwardly from the volume space 34 of rotary piston 12.It does not rely on the final pivotal position of rotary piston 12 and the corresponding maximum loading height 36 of volume space 34 in principle and acts on.
In order to cause the rotation of eccentric shaft 22, in order to rotate rotary piston 12 to expect final pivotal position or to expect region, final pivotal position or be rotated further eccentric shaft to make lubricant oil from volume space 34 part shift out, the generator be coupled with eccentric shaft 22 preferably can be used as motor and carrys out work.Alternatively also independent drive unit can be set.
Embodiment 2:
Figure 4 and 5 are the second embodiment to rotary-piston machine according to the present invention be described.The first embodiment that this second embodiment illustrates with above-mentioned Fig. 1 to 3 is in an advantageous manner capable of being combined.
In the rotary-piston machine shown in Figure 4 and 5, in side dividing plate 28, be configured with fluid openings 38.This fluid openings is positioned at the top of scraper plate ring 32, thus, in each pivotal position of rotary piston 12, even that is on the extreme higher position of rotary piston 12, be all connected with volume space 34 liquid.
Fluid openings 38 is connected with liquid manifold room further, and this liquid manifold room is such as oil sump
it is equally also a part for oily circulation loop.In addition, fluid openings 38 is also assigned rectifying device (not shown).By means of rectifying device, fluid openings 38 can keep closing under the normal working of rotary-piston machine.
After rotary-piston machine is closed and after the oil pump closedown of oil circulation, fluid openings 38 opened by rectifying device, thus in the volume space 34 of rotary piston 12, lubricant oil enters oil sump from volume space 34 at least partially.In this way, after rotary-piston machine is closed, the lubricants capacity be retained in the volume space 34 of rotary piston 12 just decreases.Consequently, can make in the down period of rotary-piston machine, less oil seepage enters in working room 14.
By the lubricant oil oil-feed drain pan that will discharge, lubricant oil can continue to use in oil circulation loop and goes.Consequently, among the running that less lubricant oil can be used for rotary-piston machine.
