Definitions
- the invention relates to a camshaft adjuster for internal combustion engines.
- Camshaft adjusters of the abovementioned type serve in each case to enable as optimally as possible or variable valve actuation. They offer the possibility of adjusting the phase angle of the valve control continuously and in a controlled manner.
- Hier ⁇ to a camshaft adjuster is rotatably and non-positively connected to the respective Nocken ⁇ wave.
- a rotational movement is transmitted to the camshaft, thereby providing a respectively desired adjustment of the camshaft relative to the crankshaft of the internal combustion engine.
- camshaft adjusters are usually driven hydraulically.
- the oil pressure required for adjusting the camshaft is obtained from the lubricating oil pressure circuit assigned to the respective combustion engine.
- the camshaft is not yet in the desired relative position to the crankshaft, especially in the exhaust-gas-critical engine starting phase.
- camshaft adjusters which continuously vary the angular position of the camshaft, is represented by systems which are constructed according to the Schwenkmotor ⁇ principle.
- a drive wheel has a cavity formed by a circumferential wall and two side walls, in which at least one hydraulic working space is formed by at least two boundary walls.
- a wing extending into the hydraulic working space divides the hydraulic working space into two hydraulic pressure chambers. Gaps between a head of a pressure medium distributor and an opening of the one side wall of the drive wheel and / or between the lateral surface and an opening of the other side wall of the drive wheel are sealed by wear-resistant sealing means against pressure medium leaks.
- a vane-cell adjusting device in which between a swivel impeller and a drive wheel enlarged trained radial gaps are provided, while the sealing elements than in both directions of rotation of the
- Schwenkeries swiveling pendulum sealing strips are formed, which are pivotable with pressure force of the hydraulic pressure medium against the respective counter surface on the drive wheel or the swing impeller.
- a drive unit is pivotally mounted on a driven unit via a plurality of radial bearing points, wherein at least the surfaces of the individual radial bearing segments of the drive unit and the opposite radial bearing segments of the output unit and optionally also the axial contact surfaces between the drive unit and he output unit are formed with a friction-reducing coating.
- Patent Abstracts of Japan JP 11013431 discloses a vane-type adjusting device in which, in order to achieve a compact construction, the rotation is transmitted by means of three bolts which engage in corresponding oblong holes in the housing of the vane-cell adjusting device.
- the problem with such Nockenwellenverstellem is that to avoid larger internal leakage in the pressure chambers tight tolerances must be met, which can be met only costly, especially if such Bau ⁇ parts are made sintering technology. In a sintering production, these tolerances are therefore only by a corresponding complex mechanical processing, or on significantly reduced quantities reachable.
- interlocks or return springs have to be installed in order to ensure the function in the so-called "hot idling".
- the invention has for its object to provide a camshaft adjuster for Verbren ⁇ ubenskraftmaschinen, which prevents internal radial leaks and pondere ⁇ is low to produce.
- stator planetary gear wheel rolls off on the toothed segment of the inner rotor and the rotor blade planetary gear, which is mounted in the rotor blade, rolls down on the toothed segment of the stator.
- the geometry of the toothing must be designed so that the toothing data of the planet wheels, which are mounted in the rotor blade and in the stator blade, are the same.
- the production costs are lowered, since only one tool is needed in the sintering technology of the rotor blade planet wheels and the stator planetary gears.
- the adjustment of the inner rotor takes place in that pressure is applied to a pressure chamber, wherein in response to the applied pressure chamber, the pressure against the inner rotor blade and this accordingly rotates.
- the oil pressure in the pressure chamber pressurizes the stator blade planetary gear meshing with the inner rotor gear segment, thereby forcing the tooth tips of the stator blade planetary gear against the stator blade bearing pocket wall and the stator flywheel tooth flanks against the tooth flanks of the stator wing planetary gear Veryakungs ⁇ segments of the inner rotor are pressed.
- the stator has at least two stator blades and the rotor has at least two rotor blades. In a further advantageous embodiment, it is provided that the stator has three stator blades and the rotor has three rotor blades. In a likewise advantageous embodiment, it is provided that the stator has four stator blades and the rotor has four rotor blades.
- Known camshaft adjusters generally have four stator blades and four rotor blades, as a result of which the possible angle of rotation of the camshaft is limited by design.
- a reduction of the number of stator blades and rotor blades to two or three blades leads to the result that, on the one hand, larger angles of rotation can be realized and, on the other hand, the camshaft adjusters become lighter and there is less mass for moving parts. Structurally, more than four wings are possible.
- stator, the inner rotor and / or the planet wheels are made of sintered metal. These parts can be sintered with larger tolerances without the radial sealing worsened. Furthermore, the sensitivity to contaminated oil is low.
- rotor, stator and the planetary gears have at least approximately equal coefficients of thermal expansion, so that these components can be paired with one another. It is possible with approximately the same thermal coefficient, for example, a rotor and Sta ⁇ gate made of sintered steel and the planet gears made of a plastic (Duroplast) use. In particular, this results in a reduction of the noise due to the combination of sintered steel / plastic.
