Definitions
- the invention relates to a device for relative Angular adjustment of a camshaft according to the preamble Of claim 1 further defined type.
- a generic device is known from DE 197 26 300 A1 known. It is between the impeller and the housing wheel arranged a spring element, which the impeller holds in a basic position. Thereby The impeller may also be without applied oil pressure do not move and it is ensured that when Starting the engine no longer sounds occur and the desired valve timing also are set for the exhaust valve.
- the housing wheel can be inexpensive be made by sintering, which is a big one Expenditure on cutting machining unnecessary Furthermore, the spring elements can easily in the cavity between. the impeller and the housing wheel to be assembled.
- Fig. 1 shows a device 1 for relative angular adjustment a camshaft, not shown opposite the driving crankshaft, which also not shown.
- the camshaft for the operation of also not illustrated exhaust valves in a known manner working internal combustion engine provided, the device 1, however, is as described below Shape also for use with an intake camshaft usable.
- the device 1 has a drive element 2, which in this case as a so-called housing 2 is trained.
- a drive element 2 For connection to the crankshaft is the housing 2 at its periphery with a one-piece formed with the housing 2, double executed teeth 3 for a not shown Chain provided.
- an impeller 4 Inside the hollow case wheel 2 there is an impeller 4, which is the output element forms and with the camshaft in not shown, however, in a manner known per se is.
- the housing 2 has four inwardly projecting projections 5, in other embodiments also another number of projections 5 would be conceivable.
- the Impeller 4 is with four outwardly projecting wings. 6 provided, which in each case in between the individual Projections 5 formed recesses or cavities 7 of the housing wheel 2 are located. Fill in here the wings 6, the recesses 7 but not from.
- the Impeller 4 can thus a slight rotation within of the housing wheel 2, which is the difference between the length of the recesses 7 and the Length of the wings 6, each viewed in the circumferential direction, equivalent.
- the spring elements 8 push the wings 6 to the edge of the Projections 5 and thus hold the impeller 4 in his Basic position in which the camshaft realized "normal" valve timing. Through moments, which occur as a result of friction is the camshaft and thus the impeller 4 always strives, to move away from the projections 5, what an adjustment of the valve timing in the direction of late opening of the exhaust valves would result.
- it is indispensable that the impeller 4 in his basic position is.
- a secure guidance of the spring elements 8 is characterized ensures that in the projections 5 pocket-like Recesses are 9, in each of which Spring elements 8 are introduced. To. Recording the spring elements 8 also have the wings 6 pocket-like Recesses 10 on.
- the spring elements 8, which in this case are designed as compression springs are located thus in the cavities 7 between the projections 5 and the wings 6.
- the recesses 10 point in In this case, a smaller depth than the recesses 9th
- the bag-like Recesses 9 of the projections 5 in the axial Direction open to make the production easier Recesses 9 and easier assembly of the spring elements 8 to allow. That's the way it is namely an inexpensive sintering of the housing wheel. 2 possible.
- the pocket-like recesses 10 can be open in the axial direction, resulting in the possibility results, the impeller 4 also to produce by sintering. Of course it is also the production of the recesses 10 in the impeller 4 possible by drilling. In this case it would then act around closed recesses 10.
- Fig. 2 further shows that on the housing wheel 2 and on the impeller 4, a locking device 11 is provided, through which the impeller 4 can be locked in its normal position.
- the locking device 11 of known per se Type is, will not be closer to the same in the following received.
- a so-called central screw 12th arranged within the impeller 4 is also in itself known manner, a so-called central screw 12th arranged. Within the central screw 12 is located There is a control piston 13 of likewise known type. The central screw 12 and the control piston 13 Together form a 4/2-proportional valve as a control device.
- various annular channels 14, which are in the impeller 4 released and through insertion holes 15 in the impeller 4 or: in the central screw 12th entering oil causes the adjustment of the impeller 4 with respect to the housing 2 in per se known Wise.
- the existing Oil of the internal combustion engine can be used, i. the device 1 can in the oil circuit of the internal combustion engine to be involved.
- the adjustment of the impeller 4 takes place so long until a sensor, not shown, the correct set valve timing is detected. thereupon be the corresponding ring channels 14 and so that the holes 16 and 17 closed. In the Cavities 7 enclosed medium holds the impeller 4 in the set position. It is about this involves a continuous adjustment with, like indicated above, integrated 4/2 proportional valve.
- the device 1 points in the axial direction at both Side cover 18 and 19, which by screws 20 connected to each other.
- the lid 18 and 19 limit in this case, the space in which an oil pressure can be applied.
