Definitions
- the present invention relates to an adjustable camshaft to the valve train of an internal combustion engine, comprising an outer shaft and a rotatable inner shaft in the outer shaft, and having a phase divider with which the outer shaft and / or the inner shaft is adjustable in a phase axis formed about a rotation axis, and wherein the Camshaft having a bearing portion for supporting the camshaft through which the phase divider is fed with a pressure medium.
- Adjustable camshafts are used for variable valve train of an internal combustion engine, and by the phase divider can be adjusted relative to the phase angle of the outer shaft during the rotation of the adjustable camshaft, the phase angle of the inner shaft. It is also possible to adjust the phase angle of the inner shaft and the outer shaft together relative to the phase position of a drive wheel, via which the camshaft is driven to rotate about the axis of rotation. So-called dual-phase control, for example, allow the change of the phase position of the outer shaft and the inner shaft together and at the same time the adjustment of the phase angle of the inner shaft relative to the outer shaft is possible.
- Phase dividers are usually operated by a pressure medium, in particular an oil, by alternating pressure chambers formed between a rotor and a stator of the phase adjuster are applied fluidly.
- the supply of the pressure medium is usually carried out via a bearing portion on the outer shaft of the camshaft, via which the camshaft is mounted in a bearing bracket.
- the bearing section forms the outermost bearing section at the end of the camshaft, so that the outer shaft and in particular the inner shaft with the bearing section along its longitudinal direction complete the axis of rotation and followed by the end in the direction of rotation axis of the phase divider.
- the stator of the phaser is usually attached.
- the phase divider in particular the rotor, is fastened to the inner shaft with a central screw, particular difficulties arise in accommodating the channels in the inner shaft and / or the outer shaft due to the reduced installation space.
- DE 10 2006 028 61 1 A1 shows an adjustable camshaft with a phase divider, which is bolted to the end of the inner shaft with a central screw.
- the outer shaft is rotatably received in a bearing ring, wherein the bearing ring is formed with the outer shaft co-rotating.
- the bearing ring is received in a repository, which is formed by the bearing bridge, for example, the camshaft module or the like and not co-rotated.
- Another adjustable camshaft is known from DE 10 2006 013 829 A1, and the inner shaft of the camshaft has a threaded bore into which a central screw can be screwed in order to fasten the phase divider to the camshaft.
- the accommodation of the oil passages must therefore be provided on the radial region between the threaded bore and the receptacle of the mounting flange, which is seated on the outer shaft end. Due to the limited space available to accommodate the oil passages, the arrangement of a dual-phaser, for example, already not readily possible.
- the object of the invention is the development of an adjustable camshaft with an improved arrangement of a phaser at the end of the camshaft.
- an enlarged installation space is to be created in order to improve a pressure medium guide between the bearing section and the phase divider.
- the invention includes the technical teaching that the inner shaft has an end to which a Verschraubungsflansch is arranged and wherein the Verschraubungsflansch a rotor of the phaser is connected, and wherein the free end of the inner shaft coinciding with the axis of rotation channel for at least partially feeding the Phase actuator having a pressure medium, which channel extends at least into the bearing section.
- the core of the invention is the redesign of the connection of the phaser to the adjustable camshaft, which is developed such that a screw lying in the axis of rotation at the end of the inner shaft can be omitted to arrange the phase divider to the camshaft.
- the central screw in the present sense is a screw which is screwed into the end of the inner shaft, and the screw is concentric with the axis of rotation. If this screw is omitted by an inventive development of the adjustable camshaft with the features of the present invention, then there is a significantly increased space for the design of the channels to produce a pressure fluid connection between the bearing portion and the phase divider.
- the invention provides a central channel, which coincides with the axis of rotation and opens at the end of the inner shaft to the outside or in the phase divider, so that a phase divider, the end the camshaft is arranged, at least can be fed via the central channel with a pressure medium.
- connection of the rotor to the fitting flange has screw elements, wherein the screw elements are arranged at a distance from the axis of rotation.
- a single screw may be sufficient to connect the rotor of the phaser with the Verschraubungsflansch, but advantageously a plurality of circumferentially, for example, equally distributed screw elements are provided, which are arranged on a formed around the rotation axis pitch circle around.
- the screw elements extend with their longitudinal axis, for example, parallel spaced from the axis of rotation and can be screwed from the outside of the phaser, in particular the rotor, for which the Verschraubungsflansch has threaded holes, for example.
- the gland flange is applied to the end of the inner shaft by a transverse press fit or by a longitudinal compression bandage, it is also conceivable that the gland flange material fit, for example, by a welding process, a soldering process or an adhesive method, is connected to the end of the inner shaft. It is particularly advantageous if the screw connection flange is centered with a required accuracy on the end of the inner shaft, so that the rotor of the phase adjuster can in turn be centered via the screw connection flange. Furthermore, there is the possibility that the bolting flange is formed integrally with the inner shaft, so that a Connecting arrangement between the Verschraubungsflansch and the inner shaft advantageously eliminated.
- At least one oil guide sleeve is formed in the channel to form an annular gap between the outer surface of the oil guide sleeve and the inner surface of the channel, the oil guide sleeve forming a first oil channel on the inside and a second oil channel with the annular gap.
- a corresponding development of the pressure medium supply of the phaser provides that in the channel a first oil guide sleeve and at least a second oil guide sleeve are introduced, wherein the oil guide sleeves are arranged one inside the other and in particular concentric to the axis of rotation.
- the oil guide sleeves have different lengths and thus extend at different depths into the channel, so that the oil channels formed inside and / or between and / or on the outside of the oil guide sleeves are fluidically connected with separate radial channels in the outer shaft and / or inner shaft.
- the individual oil guide sleeves are advantageously to be connected so that separate oil passages between the sleeves are achieved.
- At least one of the oil passages is formed in sections in Verschraubungsflansch, i. continues into this.
- an oil passage which is formed by an annular gap between the outer side of the inner shaft and the inner side of the outer shaft, fluidically communicates with an oil passage, continues into the Verschraubungsflansch.
- the Verschraubungsflansch can also be included in the pressure medium guide between the bearing section and the phase divider.
- the outer shaft has an end on which a drive wheel is arranged and wherein at the drive wheel, a stator of the phaser is at least indirectly connected.
- a stator of the phaser is at least indirectly connected.
- the connection of the stator to the drive wheel has a compliance element, in particular a flexible disk.
- at least a part of the phaser, ie the rotor or the stator should have a rigid, centered arrangement on the inner shaft or on the outer shaft, so that the at least one other part of the phaser is guided on the centered part.
