Definitions

  • the invention relates to a device for the relative angle adjustment between two rotating, drive-connected elements according to the preamble of claim 1.
  • a sprocket is assigned to the camshaft in the drive from the crankshaft, which drives the camshaft by means of a transmission element.
  • the transmission link allows the relative angular position of the two rotating elements to be changed. This change is brought about by an electric actuator, the rotor of which acts on an actuating shaft of the transmission element and which rotates in every operating state of the device.
  • the invention has for its object to provide a device in which the actuator has a low electrical energy consumption and the device has a safe emergency operation.
  • An important advantage of the invention is that in normal operation the transmission element can be blocked with the relative angular position of the two rotating elements unchanged and the actuator does not require any energy. This leads to an overall lower energy consumption and thus to a lower thermal load on the actuator. Should there still be an inadmissible heating of the actuator, it can be stopped for cooling while the internal combustion engine is running, without this leading to an uncontrolled adjustment of the relative angular position of the two rotating elements.
  • the transmission in which when the actuator is de-energized, the rotor of which is operatively connected to at least one of the rotating elements, the transmission is automatically blocked if the actuator fails. tion member, thus a trouble-free emergency operation is guaranteed.
  • 1 denotes a rotating element which is designed as a camshaft.
  • a further rotating element 2 which is designed as a chain wheel, is assigned to the rotating element 1 in the drive of a crankshaft, not shown, of the internal combustion engine.
  • the rotating element 2 drives the rotating element 1 by means of a transmission link 3, so that the rotating element 1 and the rotating element 2 have the same speed.
  • the rotating element 2, which carries a chain on its circumference, is arranged concentrically with the rotating element 1 and surrounds it, the transmission element 3 being located between the rotating element 1 and the rotating element 2.
  • This transmission member 3 can be used, for example, as a planetary gear, swash plate gear or the like. be formed and has an actuating shaft 4 which is acted upon by a rotor 5a of an electric actuator 5. The drive torque required for the adjustment is generated between the rotor 5a and a stator 5b of the actuator 5.
  • the relative rotation of the two rotating elements 1, 2 can be changed by a relative rotation of the adjusting shaft 4.
  • the relative rotation of the actuating shaft 4 is effected via the rotor 5a of the actuator 5.
  • the actuating shaft 4 can be operatively connected to one of the rotating elements 1 or 2, the operative connection between the actuating shaft 4 and the rotating element 2 being shown in the exemplary embodiment.
  • the control shaft 4 is operatively connected to the rotating element 2 by the rotor 5a of the actuator 5, which is axially displaceably connected to the control shaft 4. Through the operative connection of the control shaft 4 with the rotating element 2, the transmission member 3 is blocked, whereby the relative angular position of the two rotating elements 1 and 2 remains constant.
  • the rotor 5a When the actuator is de-energized, the rotor 5a is operatively connected to the rotating element 2.
  • the operative connection between the rotor 5a and the rotating element 2 takes place through an axial force application F A1 of the rotor 5a, the application being generated by means of a plate spring 6.
  • Other operating principles can also be used to generate this axial force F A ⁇ .
  • an axial force component F A2 between the stator 5b and the rotor 5a of the actuator 5 is effective. This can be done, for example, by an axial offset 7 between stator 5b and rotor 5a, since this offset 7 causes the magnetic force effect between rotor 5a and stator 5b to cause this axial force component F A2 .
  • the rotor 5a In order not to mount the rotor 5a fixed to the housing and thereby generate frictional losses, the rotor 5a is mounted on the rotating element 1, bearing on another rotating element, such as the setting shaft 4, also being conceivable.
  • the operative connection between the actuating shaft 4 and one of the rotating elements 1, 2 can also take place by means of a component which is not shown here and which can be controlled separately.
  • the component can be designed as a frictional connection element, such as a brake, and / or as a form-locking connection element, such as a clutch, and / or a non-positive connection element, such as a magnetic coupling.

Abstract

L'invention concerne un dispositif de réglage angulaire relatif de deux éléments rotatifs, reliés en entraînement par l'intermédiaire d'un élément de transmission présentant un arbre de réglage, actionné par un rotor d'un entraînement de réglage électrique, la modification de la position relative dudit élément de transmission par rapport aux éléments rotatifs permettant de modifier la position angulaire relative de ces derniers. L'invention vise à mettre en oeuvre un dispositif de réglage angulaire relatif de deux éléments rotatifs de manière que l'entraînement de réglage présente une faible consommation d'énergie et ledit dispositif présente un fonctionnement auxiliaire sûr. A cet effet, l'arbre de réglage peut être relié activement à au moins un des éléments rotatifs.
