Definitions

  • the present invention relates to a device for adjusting a camshaft an internal combustion engine with at least one Electric motor that opposes the adjustment of the camshaft via a planetary gear causes a drive wheel, wherein the planetary gear a first ring gear and has a second ring gear, and at least one first planet gear, which is in engagement with the first ring gear and at least one second planet gear, that is in engagement with the second ring gear and that is fixed with the first Planet gear is connected.
  • EP-A 0 903 471 describes a device for adjusting the camshaft Internal combustion engine known, which comprises a planetary gear.
  • the gear ratio the planetary gear is limited in this device, so a relatively large electric motor has to be used to apply the required adjustment torque.
  • the backlash has an effect of the planetary gear adverse to the operating noise and Life of the device.
  • DE 41 33 408 A shows a camshaft adjusting device with a planetary gear, which has two firmly connected ring gears, one have slightly different diameters.
  • Each of the ring gears stands engages with a planet gear, one of the planet gears with the camshaft and another is connected to the drive wheel.
  • the two ring gears are eccentric to the axis of the camshaft and the drive wheels in one Mounted sleeve, which in turn is rotatably mounted about the camshaft axis. If the sleeve rotates at the camshaft speed, there is no adjustment in relation to the drive wheel. By braking or accelerating the The sleeve can have a corresponding relative movement of the camshaft the drive wheel can be effected. With such a device, it is difficult to to master the occurring mass forces and it becomes the gears comparatively heavily used.
  • EP 0 143 368 A shows a shaft coupling system that has a relative adjustment between a drive shaft and a camshaft.
  • Two planetary gears are connected in series by the planet carrier are interconnected. The relative adjustment can thereby be accomplished that the two ring gears are concentrically arranged be twisted against each other. With this device, however, are also stationary Operating the planet gears in motion, causing corresponding losses and results in noise.
  • a gearbox as in GB 649 221 A is disclosed.
  • the object of the present invention is to avoid these disadvantages and to develop a device of the type described above so that a safe Adjustment is achieved with low losses, with the required torque should be as low as possible.
  • these tasks are solved in that several planetary gear sets are provided, each consisting of a first planet gear and a second planet gear that the drive gear with the first ring gear fixed is connected that the camshaft is firmly connected to the second ring gear, that a first gear ratio between the first planet gear and the first ring gear and a second gear ratio between the second planet gear the second ring gear slightly different from each other and that the first planet gear and the second planet gear are on one Planet carriers are mounted, which are concentric to the axis of the camshaft and the drive wheel is mounted.
  • An essential feature of the present invention is that in stationary operation, that is, when an adjustment of the Camshaft takes place, there is no rolling of the planet gears in the ring gears.
  • the electric motor can basically as a moving Electric motor can be designed, as described in EP 0 903 471 A. or as a fixed electric motor, as in the DE 41 10 195 A is shown.
  • the housing of the electric motor firmly with the camshaft or the drive shaft is connected and that the electric motor is supplied with power via slip rings becomes.
  • a standstill of the electric motor means that no adjustment of the camshaft relative to the drive wheel causes becomes. Stationary operation is thus possible in a simple manner.
  • the stator of the electric motor is fixed to the housing.
  • the Electric motor run at a speed that is proportional to the camshaft speed is. An adjustment is made by acceleration or deceleration of the electric motor.
  • the backlash can be reduced or completely in a simple way be avoided that the planetary sets are arranged movably in the radial direction are. In this way, the noise level can be further reduced.
  • the planetary gear sets are designed to be pressed against the ring gears by a spring.
  • a particularly advantageous design variant of the invention is characterized in that the housing of the electric motor on the planet carrier is attached.
  • the electric motor runs as a whole around the camshaft axis, preferably the axes of the planet gears coincide with the axis of the electric motor.
  • the invention provides that the electric motor carries a pinion that with the first planet gear or the second planet gear is engaged.
  • a fixed electric motor can be used favorably can be controlled without the use of slip rings.
  • first planet gear and the second planet gear in one piece and with the same Teeth are formed and that at least one ring gear a profile shift having.
  • This allows the first planet gear and the second planet gear be practically indistinguishable as a single gear.
  • the pinion of the electric motor can engage in both planet gears, whereby a particularly favorable strength is achieved training.
  • the different profile displacement of the ring gears results in a different one virtual roll diameter. It is particularly advantageous in this Relationship when the number of teeth of the first planet gear and the second Planetary gear are the same and that the number of teeth of the first ring gear and the second ring gear are slightly different, the difference preferably makes up exactly as many teeth as planetary sets provided are.
  • the Ring gears have 100 or 102 teeth, whereby the gear ratios Make little difference between the planet gear and the first or second ring gear. In this way, the gear ratio between the electric motor and adjustment movement can be made very large.
  • Variant c is shown in the toothing diagram of FIG. 2. It is can be seen that the electric motor 8 is attached to the planet carrier and the planet gears 5, 6 drives directly. Depending on the existing force relationships can have between three and seven electric motors 8 and related planetary gear sets 12 may be provided, which are constructed from planet gears 5, 6. Around To minimize the backlash, 7 springs 9 can be provided in the planet carrier be that press the planetary gear sets 12 onto the ring gears 3, 4. The supply the electric motors 8 takes place in this solution via not shown Slip rings.
  • a stationary one drives Electric motor 8 directly on the planet carrier 7.
  • a camshaft adjustment is done by accelerating or decelerating the movement of the Electric motor 8 opposite the camshaft 1.
  • the electric motor 8 drives both can be fixed, as well as connected to the camshaft 1 can be via a pinion 11, the second planet gear 6.
  • the planet carrier is not shown in this figure to simplify the illustration. Because the pinion 11 has a small diameter, becomes a large transmission ratio reached.
  • the present invention makes it possible to adjust a camshaft in Relative to a drive wheel in a simple manner with relatively low adjustment torques to reach.
  • the friction losses are low and the noise level limited.
