Definitions
- the invention relates to a device for the relative rotation angle change Internal combustion engine according to the preamble of patent claim 1.
- a device of the aforementioned type is known, DE 199 30 711 C1, in the pressure chambers between a cellular wheel and an impeller from axial Lines are acted upon, which are designed as bores or ring channels.
- the holes are in hub sections of the device and the camshaft intended.
- the ring channels surround a shaft of a fastening screw which is used for Holding the device on the camshaft is used.
- the not yet published DE 100 02 512 shows one with pressure chambers comparable device connected lines formed by axial ring channels become.
- the ring channels are on the one hand by an outside of a control sleeve and a bore in hub sections of the device and the camshaft and another by an inside of this control sleeve and a shaft of an axial Fastening screw formed, which connects the device to the camshaft.
- the control sleeve is facing away from a screw head of the fastening screw Positioned from the side in their construction position and rests in bores of the hub sections.
- the object of the invention is to connect the lines connected to the pressure chambers Form device by means of the control sleeve, and the assembly of the control sleeve too optimize.
- Control sleeve and the fastening screw can be installed from one and the same side are what simplifies assembly itself and supports assembly security.
- centering devices which are formed by radial support webs, for the intended use well suited and also easy to implement.
- the Support bars can either be attached directly to the shaft or to the control sleeve. But it is also conceivable in terms of construction with an insert sleeve or a casing sleeve unite and manufacture from plastic. Finally, it is possible to use the control sleeve and prepare the mounting screw as a pre-assembled unit, which is then at the Connection of the device with the camshaft in the defined construction position brought.
- An internal combustion engine 1 of the Otto type comprises several cylinders 2, 3, 4 and Camshafts 5,6 and per cylinder e.g. 2 two intake valves 7,8 and two Exhaust valves 9,10 Fig. 1 -.
- the inlet valves 7, 8 and the outlet valves 9, 10 are V-shaped housed in a cylinder head, not shown, of the internal combustion engine.
- Both camshafts 5,6 are wrapped around a corresponding drive wheel Endless drive 11 - belt or chain - connected to one another, not with one crankshaft shown is coupled and adjacent from end faces 12, 13 of the said camshafts 5,6 is effective.
- Connected coaxially to the ends 12, 13 are devices 14, 15 for hydraulically adjusting the relative rotational position thereof Camshafts. With any device, for example in the manner of a vane pump is built, the control times of the valves 7,8 to the operation of the Internal combustion engine and others with regard to optimizing exhaust emissions.
- the device 14 having a circular cylindrical configuration - it corresponds structurally of the device 15 - has a drive wheel 16 designed as a chain wheel for the Camshaft 5, a cellular wheel 17 and an impeller 19 provided with radial vanes 18 on - Fig. 3 -.
- the drive wheel 16, the cellular wheel 17 and the impeller 19 are coaxial with Camshaft 5 arranged, the drive wheel 16 and the cellular wheel 17 a form interconnected unit 20. In contrast, this is about an axis of rotation 21 rotatable impeller 19 with the interposition of the blades 18 relatively movable in Pressure chambers 22,23 of the cellular wheel 17 housed.
- Each pressure chamber 22.23 - each Device 14, five pressure chambers are provided - is with a first stop surface 24 and a second stop surface 25 for corresponding first and second Stop surfaces 26,27 of the wing 18 equipped. All stop surfaces 24.25 and 26, 27 run radially to the axis of rotation 21, but the angle ⁇ is the Include stop surfaces 24, 25, greater than the angle ⁇ of the stop surfaces 26, 27 of wing 18.
- the pressure chambers 22, 23 are also surrounded by a circular area 28 limited to which a circular surface 29 of the wing 18 is brought up. Both circular areas 28,29 are effective as sealing surfaces; at 30 are between impeller 19 and cellular wheel Circular surfaces 31, 32 forming comparable sealing surfaces are provided.
- the for adjustment of the impeller 19 serving pressure chambers 22, 23 are connected to axial lines 33, 34 - Fig. 2 - connected, which are designed for oil feed and adjacent one Fixing screw 35 are arranged. With the mounting screw 35 Device 14 held on the camshaft 5, the fastening screw 35 with a shaft 36 penetrates a hub 37 and with a threaded bolt 38 in a Threaded bore 39 of the camshaft 5 is screwed in.
- the lines 33, 34 separated from each other.
- The is connected to a radial feed line 35 annular line 33 between the shaft 36 and an inside 40 of a control sleeve 41 formed, which surrounds the shaft 36 and is arranged coaxially to the latter.
- the Line 34 has an annular cross section, is to a radial feed line 42 connected and is from an outside 43 of the control sleeve 41 and one Line bore 44 of the hub 37 limited.
- the control sleeve 41 is like that Fastening screw 35 from the same end face 12 in receiving bores 45, 46 of the hub portions 47,48 having hub 37 introduced.
- the support elements 50 are either directly on the Control sleeve 41 or with an insert sleeve 51 - Fig. 4 - connected to a corresponding fit is introduced into the control sleeve 41.
- the radial support elements 50 on the shaft 36 of the Fixing screw 35 attached directly.
- a third Embodiment - FIG. 6 - support elements 50, which with a on the shaft 36th arranged casing sleeve 52 are connected.
- the Support elements 50 and the insert sleeve 51 or sleeve 52 from one piece and suitable plastic.
- the control sleeve 41 can either independent of the mounting screw 35 in the Receiving bores 45, 46 of the hub sections 47, 48 of the device 14 and the Camshaft 5 or be installed together with said fastening screw. In the latter case, it is conceivable as the control sleeve 41 and the mounting screw 35 summarize pre-assembled unit.
