Definitions
- the present invention relates to an adjustable camshaft having an inner shaft and a coaxially arranged outer shaft according to the preamble of claim 1.
- a single-acting camshaft adjuster for adjusting an inner shaft against an outer shaft on a cam-in-cam camshaft is usually carried out by a fixedly connected to the outer shaft stator and a screwed to the inner shaft and thus firmly connected rotor.
- the stator is driven by a crankshaft via a chain / tooth / belt wheel, so that the power flow to the outer shaft takes place.
- the inner shaft can be adjusted "force-free" (not against the drive torque).
- the tolerances between rotor and stator are quite narrow, so that the internal leakage in hydraulically confirmed camshaft adjuster and thus a loss of efficiency can be minimized.
- the stator of the camshaft adjuster is usually shrunk / glued / welded to the outer shaft, whereas the rotor of the camshaft adjuster is screwed against the axial end face of the inner shaft. Since in the manufacture and assembly of the inner shaft (eg, pinning, tolerance chains) may occur inaccuracies, it may come with such a rigid mounting of the rotor on the inner shaft, that the rotor is tilted against the stator installed and so it to a contact until can lead to a complete jamming. In this case, the inner shaft can no longer be rotated against the outer shaft.
- compensation elements offer that can compensate for at least some misalignment.
- From DE 10 2012 105 284 A1 discloses a generic camshaft is known, with a camshaft adjuster for adjusting the inner camshaft and / or the outer camshaft and with a arranged between the inner camshaft and the outer camshaft on the one hand and the cam phaser on the other.
- This compensating element has a disk-like shape to improve the camshaft structurally and / or functionally.
- the torque transmission is purely frictional.
- a double camshaft adjuster in layer structure for controlling a double camshaft is known, with a first rotor-like output body and a second rotor-like output body, the body parts are arranged parallel to each other with their rotary wing parts.
- each driven body is intended for receiving at least one camshaft of the double camshaft leading out laterally from the camshaft adjuster center.
- a compensating element is additionally provided, which is a movement member providing at least one degree of freedom and permits a deflection of the enclosing output body relative to the double camshaft.
- a device for adjusting the camshaft is known from DE 20 2008 018 146 U1, which comprises a camshaft adjuster which has at least one drive wheel, a rotor, a stator with a stator housing and a camshaft with cams, and an oil feed to the camshaft adjuster.
- the No- The camshaft adjuster is held with a rotor whose inner diameter is smaller than a cam-encircling circle, positively and / or non-positively on one end of a camshaft, wherein the camshaft for receiving a recesses for oil supply connecting element has a hollow configuration, such that the connecting element in the hollow design of the camshaft is held positively and / or non-positively.
- Either the connecting element or the rotor have at least one driver for the positive connection of the rotor with the camshaft and the connecting element, said driver being guided by at least one recess in a hollow end of the camshaft piercing.
- the present invention is concerned with the problem of providing for an adjustable camshaft of the generic type an improved or at least one alternative embodiment, which in particular allows improved tolerance compensation in the connection of a rotor to the inner shaft.
- the present invention is based on the general idea, in an adjustable camshaft with an inner shaft and a coaxially arranged outer shaft, a rotor of a camshaft adjuster with the inner shaft of the adjustable camshaft form-fitting, in particular via an Oldham coupling to connect with each other, this Oldham coupling simply or according to the Oldham principle acting is designed.

- the inner shaft provided an integral first connection contour and on the rotor a complementarily formed integral second connection contour, the direct (single acting Oldham coupling) or indirectly (double acting Oldham coupling) a positive connection between the inner shaft and the rotor as well as any required Allow tolerance compensation.
- the rotor may for example be formed as a sintered part, wherein the second connection contour is integrally formed on the rotor and thereby produced together with this.
- the first connection contour is integrally formed on the end face of the inner shaft, so that in the simplest case, a direct engagement of the two connection contours allows the desired positive connection in the form of a single-acting (in one direction) Oldham coupling.
- the first connection contour as a spring and the second connection contour are designed as a groove formed complementary thereto, so that the first connection contour and the second connection contour together form a single-acting Oldham coupling.
- the spring and the groove are aligned parallel to a, a first cam with the inner shaft connecting pin. Due to the parallelism between the groove and the pin connecting the first cam with the inner shaft, it is possible to compensate for the expected error in this direction. Since in this case the inner shaft engages directly with its connection contour in the connection contour on the rotor, can be dispensed with an intermediate piece, but a tolerance compensation is possible only in one direction.
- the first and / or second connection contour is formed dome-shaped. Such a channel-type design makes it possible to compensate for angular tolerances between the axis of the rotor of the camshaft adjuster and the axis of the inner shaft.
- connection contour in the rotor or on the inner shaft can be dispensed with an additional intermediate piece.
- an intermediate piece is arranged between the inner shaft and the rotor, which is designed such that it forms an Oldham coupling together with the first and second connection contour on the end face of the inner shaft or on the rotor.
- Such Oldham coupling allows tolerance compensation between the axis of the rotor and the axis of the inner shaft, provided that they are arranged axially parallel to each other.
- connecting contours on the intermediate piece and / or the first connection contour on the inner shaft and / or the second connection contour on the rotor are formed as a rounded spring or as a rounded groove, whereby in addition to the compensation of tolerances due to an axial deviation between the axis of the inner shaft and The axis of the rotor and angular deviations with respect to these two axes are compensated.
- an axial bearing of the inner shaft via the rotor of the camshaft adjuster is possible. Radial, the inner shaft can be stored on the pinning.
- At least one connecting contour designed as a rounded spring has a plane surface on the spring head.
- a further advantageous embodiment uses an intermediate piece arranged between the inner shaft and the rotor, which is designed in such a way that it forms an Oldham coupling together with the first and second connecting contours on the end face of the inner shaft or on the rotor and has simply designed springs engage some play in the complementary groove and / or having rounded springs.
- at least one of the axial separating surfaces between the rotor and intermediate piece or intermediate piece and inner shaft designed dome-shaped.
- connection contours is coated, in particular with an elastomer material.
- an elastomer material for the purpose of damping effect and others Tolerance compensation, it is thus possible to coat the intermediate piece or corresponding contact surfaces and / or connection contours with a damping material, which in particular has a positive effect on the smoothness of an engine equipped with such a camshaft.
