Definitions
- the invention relates to a device for relative angular displacement between two rotating, drive-connected elements according to the preamble of claim 1.
- From the DE 100 36 275 A1 is a generic device for relative angular displacement between a camshaft and a crankshaft of an internal combustion engine known.
- the camshaft is assigned in the drive of the crankshaft a sprocket, which drives the camshaft through the intermediary of a transmission member.
- the transmission member makes it possible to set a change in the relative angular position of the two rotating elements. This change is effected by an electric actuator whose rotor acts on a control shaft of the transmission member and which rotates in any 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 safe emergency.
- a significant advantage of the invention is that in normal operation, the transmission member can be blocked with unchanged relative angular position of the two rotating elements and the actuator requires no energy. This leads to an overall lower energy consumption and thus to a lower heat load of the actuator. Should it nevertheless come to an impermissible heating of the actuator, this can be stopped when the engine is running for cooling, without leading to an uncontrolled adjustment of the relative angular position of the two rotating elements.
- an automatic blocking of the transmission element thus a trouble-free emergency is guaranteed.
- 1 denotes a rotating element, which is designed as a camshaft.
- the rotating element 1 is in the drive of a crankshaft, not shown, of the internal combustion engine, a further rotating element 2, which is designed as a sprocket assigned.
- the rotating element 2 drives the rotating element 1 through the intermediary of a transmission member 3, so that the rotating element 1 and the rotating element 2 have the same rotational speed.
- the bearing at its periphery a chain, rotating element 2 is arranged concentrically to the rotating element 1 and encloses this, wherein the transmission member 3 is located between the rotating element 1 and the rotating element 2.
- This transfer member 3 can, for example, as a planetary gear, swash plate mechanism o.ä. 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 adjusting is generated between the rotor 5a and a stator 5b of the actuator 5.
- control shaft 4 is according to the invention with one of the rotating elements 1 or 2 operatively connected, wherein in the embodiment, the operative connection between the adjusting shaft 4 and rotating element 2 is shown.
- the operative connection of the control shaft 4 with the rotating element 2 is effected by the rotor 5a of the actuator 5, which is connected axially displaceable with the control shaft 4.
- the transmission member 3 is blocked, whereby the relative angular position of the two rotating elements 1 and 2 remains constant.
- 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 the stator 5b and the rotor 5a, since the magnetic force action between the rotor 5a and the stator 5b causes this axial force component F A2 through this offset 7.
- the rotor 5a In order to store the rotor 5a not fixed to the housing and thereby to generate friction losses, the rotor 5a is mounted on the rotating element 1, wherein a bearing on another rotating element, such as the control shaft 4, is conceivable.
- the operative connection between the control shaft 4 and one of the rotating elements 1, 2 can also be done by a not shown here, to be controlled separately component.
- the component may be formed as a frictional connection element, such as a brake, and / or as a positive connection element, such as a clutch, and / or a frictional connection element, such as a magnetic coupling.
- Each of the above-described active connection options can advantageously be effected by friction.
