Definitions
- the invention relates to an internal combustion engine in which the speed of rotation of a cam Gas exchange control is cyclically changeable by a Intermediate link in a plane perpendicular to the axis of rotation a camshaft slidable and in any position is rotatable within this plane.
- Such a rotary drive arrangement is preferably used for driving cams to control an intake or Exhaust valve of an internal combustion engine.
- the degree of change i.e. the amount of temporary increase in angular velocity and temporarily lowering the angular velocity of the Nockens and the phase of these changes depend on the position that an intermediate link has with respect to a Driveshaft. With a concentric position of the Intermediate link with respect to the drive shaft rotates the cam synchronous with the drive shaft.
- the object of the invention is such Engine to run so that the mechanism to cause the cyclical change of the Rotation speed of the cam is compact, inexpensive and easy to manufacture, one stiff storage of the component enables and by simple control means can be actuated.
- the invention based on a common Inner eccentric two separate outer eccentrics are stored, is particularly suitable for an internal combustion engine a camshaft that is both intake and Exhaust valves drives. This can be a special compact structure can be achieved.
- the control or Rotation of the inner eccentric and the two External eccentric can have appropriate sprockets take place, the outer eccentrics either separately or can be controlled together.
- a rotary drive arrangement that is cyclical generates variable cam movement, has a shaft 1 with a central axis 5, which in the in the first to 3 shown embodiment of a drive shaft 1st corresponds to these rotary drive regulations.
- an inner eccentric 30 is mounted, with a for storage Needle roller bearings can be used.
- the inner eccentric 30 by means of a Thrust washer 38 and a snap ring 39 against Be secured to the left in Fig. 2.
- the inner eccentric 30 has a base body 31 and an eccentric seat 32, through which a bore 33 for receiving the shaft 1 runs.
- the base body 31 has a circular outer contour 37, the central axis of which coincides with the central axis 5 of the shaft 1, which is also the axis of rotation.
- the outer contour 35 of the eccentric seat 32 has a central axis which is offset by a first eccentricity e 1 with respect to the central axis of the bore 33 and thus with respect to the axis of rotation 5.
- An outer eccentric 40 is rotatable on the outer contour 35 stored.
- the outer eccentric 40 has a bore 41, those for receiving the outer contour 35 of the eccentric seat 32 the inner eccentric 30 is used.
- the outer contour 45 of the outer eccentric 40 is offset from the central axis of the bore 41 by a second eccentricity e 2 .
- the eccentricities e 1 and e 2 can be chosen freely, but are preferably the same in amount.
- An inner eccentric ring gear 34 is non-rotatable with the Outer contour 37 of the inner eccentric 30 connected.
- an outer eccentric ring gear 44 arranged, the rotatable on the outer contour 37 of the Inner eccentric 30 is mounted.
- the External eccentric ring gear 44 has a nose 43 (see FIG. 2), which in a groove 46 of the outer eccentric 40th intervenes.
- Rotary drive means (not shown) for controlling the respective rotational position of the inner eccentric 30 and the Outer eccentric 40 can be in the inner eccentric ring gear 34 and engage the external eccentric ring gear 44.
- control means for example, two stepper motors selected, the rotary positions of the Inner eccentric 30 and the outer eccentric 40 separately and adjust independently of each other so that the outer contour 45 of the outer eccentric 40 any position within a plane perpendicular to the central axis 5 of the shaft 1 can take.
- This intermediate link 4th has a first sliding guide 6 and a second Slideway 7, each for receiving a Slide block 13 are suitable.
- a first rotating body 2 is rotatably connected to the drive shaft 1 and points a start-up band 2a.
- On the first rotating body 2 is a formed as a gear second rotating body 3 rotatable stored.
- the first rotating body 2 has a Bore 11 into which a first designed as a pin Transmission element 8 is introduced. This pin 8 transmits the rotation of the first rotating body 2 via one the sliding blocks 13 and the first sliding guide 6 on the Intermediate link 4.
- the second rotating body 3 has a bore 12, in the second designed as a pen Transmission element 9 is introduced.
- the rotation of the Intermediate member 4 is on the second sliding guide 7 and the other of the two sliding blocks 13 and the pin 9 transferred to the second rotating body 3.
- the external eccentric ring gear 44 can extend axially over the External eccentric 40, the intermediate member 4 and the second Support the rotating body 3 against the collar 2a.
- the federal government 2a first rotating body 2 thus causes the entire Rotary drive arrangement against a shift to the right is secured in Fig. 2.
- the second rotating body 3 is designed as a gear that is engaged with a cam gear 22 so that the Rotation of the second rotating body 3 on the camshaft 21 and transmit the cam 20 connected to it in a rotationally fixed manner becomes.
- the intermediate member 4 is in a position in which its central or rotational axis coincides with the central or rotational axis 5 of the drive shaft 1, the second rotary body 3 and thus the cam 20 rotate synchronously with the drive shaft 1 Position is reached when the eccentricities e 1 and e 2 are equal in amount and the inner eccentric 30 and the outer eccentric 40 assume such a position that the two eccentricities e 1 and e 2 are diametrically opposed.
- a complete revolution of the drive shaft 1 has continue one full turn of the second Rotating body 3 and the cam 20 result in the course of this entire turn, however, there is one temporary increase in rotation speed and too a temporary decrease in the rotational speed of the second rotating body 3 and thus the cam 20.
- Das Extent of this increase in rotational speed or Rotation speed reduction depends on the offset of the Axis of rotation of the intermediate member 4 with respect to the central axis 5 of the drive shaft 1. The direction of this offset determines the phase position of the respective increase in rotational speed or reduction in rotational speed regarding the position of the cam 20.
- FIG. 4a shows an embodiment of the invention. This differs from that explained above Rotary drive arrangement in that on a common Inner eccentric 30 two outer eccentrics 40A, 40B arranged are.
- the inner eccentric 30 can Inner eccentric ring gear 34 are rotated while the External eccentric 40A, 40B over corresponding External eccentric gear rings 44A, 44B either separately or can be controlled together.
- On each of the two An intermediate member 4 is mounted on the outer eccentric 40A, 40B.
- the internal combustion engine Possibility of variation of the two valves in the case given in which the two outer eccentrics 40A, 40B can be controlled or rotated together. This will compared to the case of independent control of both External eccentric 40A, 40B a control means (not shown) saved.
- the cyclical change in the rotational speed results from the fact that, due to the axial offset of the central axes of rotation of the camshaft and the intermediate member, depending on the angular position, different driving radii r occur between the camshaft and the intermediate member on the one hand and the intermediate member and the cam on the other hand.
- the condition that the tangential speed component v tan must be constant at a constant rotational speed w NW also applies because the distance r NW of this point of engagement from the axis of rotation of the camshaft always remains constant.
- the intermediate member and thus also the Cams once with a full revolution of the camshaft faster and once slower than the camshaft.
- the lead or lag of the cam opposite the camshaft is zero. Cut at this point the output valve lift curve, i.e. the Valve lift curve, which is at a concentric Position of the intermediate link, and the modified valve lift curve, i.e. the Valve lift curve, which at the respective Axial offset between the axis of rotation of the intermediate link and the axis of rotation of the camshaft.
- Fig. 4b shows the valve lift curves in the on the Field of internal combustion engines usual representation, where OT is the top dead center of the piston, AM is the distance between the middle of the outlet and TDC, i.e. the outlet spread, and EM the distance between the center of the inlet and TDC, i.e. the Intake spread is.
- Phase angle ⁇ is the angle between the maximum of modified cam speed, i.e. the Intersection of the respective output valve lift curve with the modified valve lift curve, and the Output valve lift curve maximum. Positive values of the phase angle ⁇ mean that the modified Valve lift curve in the direction of increasing Cam flank is shifted, and mean negative values a shift towards the falling cam flank.
- the value of the phase angle ⁇ IN of the intake cam IN is preferably positive and the value of the phase angle ⁇ EX of the exhaust cam EX is preferably negative.
- the phase angle is determined by the choice the direction of displacement of the eccentricity with the respective position of the cam tip to the Valve actuator, for example one Tappet.
- Such a configuration is schematic in Fig. 4b shown, the representation under I den Inlet cam and the representation under II den Exhaust cam affects.
- the center white circle represents the Camshaft, the black surface the inner eccentric and the hatched area represents the external eccentric.
- the eccentricity e 1 of the eccentric seat for the inlet cam IN of the common inner eccentric runs approximately 45 ° downward to the left and the eccentricity e 2 of the outer eccentric 40B runs exactly in the opposite direction, so in the starting position that in this starting position the resulting eccentricity e for the intermediate member of the inlet cam IN is zero.
- the eccentricity e 1 of the eccentric seat for the exhaust cam EX of the common inner eccentric extends from the axis of rotation of the camshaft approximately 45 ° to the top left and the eccentricity e 2 of the outer eccentric 40A runs exactly in the opposite direction, so that in this starting position the resulting eccentricity e for the intermediate member of the exhaust cam EX is also zero.
- the angles ⁇ IN and ⁇ EX therefore have a different sign.
