Definitions
- the invention relates to a device for the relative rotation angle adjustment of a camshaft of an internal combustion engine to a drive wheel according to the preamble of the main claim.
- a so-called vane cell camshaft adjuster in which recesses are provided on the end faces of the rotor blades, in which roller-shaped rolling elements are accommodated. These rolling elements serve to reduce the frictional forces between the drive wheel and the impeller (rotor), the rolling elements being supported on one side directly in the recess and on the other side directly on the inner wall of the drive wheel.
- the pressurization to the two pressure chambers provided in one side wall of the rotor blades is advantageously carried out via an opening in each case, which is connected to the pressure chambers adjoining the blades.
- the pressure oil supply for adjusting the inner part or rotor can thus be used simultaneously for pressurizing the pressure chambers provided in the rotor blades. Additional pressure lines for supplying the pressure chambers are therefore not necessary.
- FIG. 1 shows a section through a camshaft adjuster
- FIG. 2 shows a section along the line II-II in FIG. 1
- FIG. 3 shows an enlarged view of a rotor blade
- FIG. 4 shows a section along the line IV-IV in FIG. 3 and
- Fig. 5 is a view of the end face of a rotor blade in the assembled state of the camshaft adjuster s.
- the camshaft of an internal combustion engine is schematically indicated at 2, at the free end of which an inner part, hereinafter referred to as rotor 4, of an adjusting unit 5 is arranged.
- the rotor 4 is provided with five radially arranged vanes 6a to 6e, which start from a hub S of the rotor 4.
- the rotor 4 is in the area of its blades 6a to 6e by a cellular wheel 10 comprises, which is provided with five inwardly projecting radial webs 12a to 12e.
- the cell wheel 10 forming the stator of the adjusting unit 5 is closed on its end face facing the camshaft 2 by a chain wheel 14 which is rotatably and sealingly guided on the hub 8 of the rotor 4.
- the sprocket 14 serves as a drive for the camshaft 2, which takes place, for example, via a drive chain connected to the crankshaft.
- the opposite end face of the cellular wheel 10 is closed by a disk 16, the chain wheel 14 and the disk 16 being firmly connected to the cellular wheel 10 by means of fastening screws 18.
- the through holes 20 provided in the webs 12a to 12e in the cellular wheel 10 serve to receive or guide these fastening screws 18.
- Five webs delimited in the axial direction by the chain wheel 14 and the disk 16 are formed by the webs 12a to 12e of the cellular wheel 10, which are divided into two pressure chambers 22a to 22e and 24a to 24e by the blades 6a to 6e of the rotor 4.
- the rotor 4 and the cell wheel 10 rotatably guided on it are attached to the camshaft 2 by means of a cylinder screw (not shown).
- the hub 10 has a central bore 26 for receiving the cylinder screw.
- a signal transmitter disk 30 is attached to the outside of the rotor 4, with the aid of which the rotational position of the camshaft 2 relative to the crankshaft can be detected.
- the five axial bores 32a to 32e arranged in the hub 8 of the rotor 4 represent part of the oil supply channels for the pressure chambers 24a to 24e.
- the pressure chambers 22a to 22e are also provided with hydraulic oil via radial bores (not shown) arranged in the hub 8 provided.
- the hydraulic oil supply for the two pressure chambers 22a to 22e and 24a to 24e takes place via a camshaft bearing 34, to which corresponding control lines for the oil pressure supply to the adjusting unit 5 are connected.
- the way in which the oil is supplied to the pressure chambers 22a to 22e or 24a to 24e is, for. B. from DE 199 39 711 Cl known, so that the exact design of the oil supply channels to the pressure chambers is not discussed further.
- the side wall 36 adjoining the chain wheel 14 and the side wall 38 adjoining the disk 16 of the wings 6a to 6e each have two recesses 40 and 42 forming a pressure chamber, both of which are separated from one another by a central web 44.
- the pressure chambers 40 are connected to the pressure chambers 22a to 22e via a channel 46 and the pressure chambers 42 are connected to the pressure chambers 24a to 24e via a channel 48.
- the two chambers 40 and 42 formed on one side surface of each of the wings 6a to 6e extend essentially over the entire side surface.
- a pressure cushion is alternately built up in the pressure chambers 40 and 42, which contributes to reducing the friction between the wings 6a to 6e and the adjacent sprocket 14 and side cover 16.
- the pressure chambers 22a to 22e are acted upon by hydraulic oil. Via the pressure chambers 22a to 22e, the hydraulic oil passes through the channels 46 into the pressure chambers 40, in which a corresponding pressure cushion is built up.
- the pressure spaces 24a to 24e are acted upon in an analogous manner with hydraulic oil.
- the hydraulic oil passes through the pressure chambers 24a to 24e and the channels 48 into the pressure chambers 42, so that a friction-reducing pressure cushion is also formed in the side region of the wings 6a to 6e in this adjustment direction.
