Definitions

  • the invention relates to a camshaft for actuating valves Internal combustion engine according to the preamble of patent claim 1.
  • the locking device comprises a between the cell wheel and Impeller coaxially arranged movable locking sleeve, which in a first Position the said wheels rotatably connected, and them in a second Position separates from each other.
  • DE 1 96 23 818 A1 is between a wing-like extension of the impeller and a cover of the cellular wheel a corresponding locking device intended.
  • the locking device is axially movable with a spring-loaded Piston provided, which - only - in the start-up phase of the internal combustion engine in a recording of the lid engages.
  • the object of the invention is to provide a locking device for a device Adjust the relative rotational position of a camshaft so that it improves the one hand can be easily integrated into the facility and secondly, by good function distinguished.
  • the main advantages achieved with the invention are the fact that the Pressure channel and the shuttle valve an excellent and especially because of the separate Pressure rooms have an immediate effect with regard to unlocking and locking the Locking device of the device for adjusting the relative rotational position of the Ensure camshaft.
  • the pressure channel and the shuttle valve can be opened easily integrated into the wing of the impeller of the device.
  • the Shuttle valve which includes a ball movably mounted in the pressure channel, is included reasonable effort realizable.
  • the stepped bore and the insert contribute to this that the ball is easy to assemble and advantageously limited. After all, it is about
  • the piston, the compression spring and the spring plate are components that are inexpensive are producible.
  • An internal combustion engine 1 of the Otto type comprises a plurality of cylinders 2, 3 and 4 two Camshafts 5,6 and per cylinder e.g. 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 in one Not shown cylinder head of the internal combustion engine 1 housed.
  • Both Camshafts 5,6 are wrapped around a corresponding drive wheel Endless drive 11- belt, chain - connected to each other, the one not shown Crankshaft is coupled and adjacent end faces 12, 13 of said Camshafts is effective.
  • On the end faces 12, 13 of the camshafts 5, 6 coaxial connected devices 14,15 for hydraulic adjustment of the relative Rotational position of these camshafts.
  • 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.
  • 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 fixed form interconnected unit 20. In contrast, this is about an axis of rotation 21 rotatable impeller 19 with the interposition of the vanes 18 relatively movable in chamber-like cells 22 of the cellular wheel 17 housed.
  • Each cell 22 - in total five cells are provided for each device - is with a first stop surface 23 and a second stop surface 24 for corresponding first and second stop surfaces 25,26 of the wing 18 equipped. All stop surfaces 23, 24 and 25, 26 run radially to the axis of rotation 21, but the angle ⁇ is the stop surfaces Include 23.24, larger than the corresponding angle ⁇ of the stop surfaces 25.26 of wing 18.
  • the cell 22 is still delimited by a circular area 27 to which one Circular surface 28 of the wing 18 is brought up. Both circular areas 27 and 28 are as Sealing surfaces effective; at 29 are comparable between impeller 19 and cellular wheel 17 Circular surfaces 30, 31 forming sealing surfaces are provided.
  • the stop surfaces 23, 24 are adjacent to the circular surfaces 27 and 30 with chamber-shaped recesses 32, 33 and 34,35 provided, via which to act on the stop surfaces 25,26 of the wing 18th of the impeller 19 hydraulic medium is introduced.
  • the impeller 19 is on the by Drive wheel 16 and the cellular wheel 17 unit 20 formed, for which a Locking device 36 is set up.
  • the locking device 36 comprises a piston 37 - Fig. 4 - in a bore 38 of the wing 18 of the impeller 19 in Axial direction of the axis of rotation 21 is displaceable and with a locking pin 39 a corresponding receptacle 40 in a hub body 41 of the assembly 20 cooperates.
  • the piston 37 which is made in one piece with the locking pin 39 is produced, is of an approximately tangentially extending in the wing 18 pressure channel 42 - Fig. 3 - acted upon, in which a shuttle valve 43 is effective.
  • the Pressure channel 41 is connected to a pressure chamber 45 of the piston by means of a radial bore 44 37 connected.
  • the shuttle valve 43 is with the stop surfaces 25, 26 on both sides of the wing 18 provided pressure spaces 46 and 47 of the impeller 19 connected by which is supplied from hydraulic medium.
  • the shuttle valve 42 has a ball 48 which is relatively movable in the pressure channel 42 is guided, which pressure channel 42 has a guide bore 49 for the ball 42. Furthermore, the pressure channel 41 is a first chamfer 50 of a first end bore 51 and a second chamfer 52 delimits a second end bore 53. Here is the diameter the guide bore 49 larger than the diameter of the end bores 51 and 53 and the chamfers 50 and 52 serve as valve seats for the ball 48.
  • the second end bore 53 and the second chamfer 52 are attached to an insert 54 which is in an insert bore 55 is set, the diameter of which is larger than the diameter of the Guide bore 48; The ball 42 is inserted into the Guide bore 48 introduced.
  • the locking pin 39 of the piston 37 which cooperates with the receptacle 40, has a smaller diameter than the diameter of the piston 37. This gives there is an annular pressure surface 56 which can be acted upon by hydraulic medium.
  • a compression spring 57 is supported, the one hand in some areas in a recess 58 of a kind of head on the locking pin 39 forming piston 37 rests and, on the other hand, is supported on a spring plate 59, which is fixed in the bore 38 of the piston 37.
  • the spring plate 59 is with a Provide guide pin 60, which is partially surrounded by the compression spring 57.
