Definitions

  • the invention relates to a mounting device for valve actuation elements in internal combustion engines, the valve actuation elements consisting of at least one valve spring, a valve spring plate with a recess for receiving fastening parts and, if appropriate, a spring seat ring, all valve actuation elements being arranged by means of a holder arranged on the valve spring plate, which has an extension extending on the outer circumference, has axial extension, the end region of which is detachably connected to the valve spring or the spring seat ring, are connected to one another as an installation unit before assembly.
  • DE-A1 39 07 001 shows an assembly device with which all valve actuation elements can be assembled with only one tool.
  • the device consists of a holder for receiving the valve actuation elements in the form of a plastic cap, which connects all the elements to form an installation unit.
  • the holder has an axial extension, the free end of which is detachably connected to the spring end axially opposite the valve spring plate or the spring seat ring.
  • the detachable The connection consists of a snap connection between the spring seat ring and the axial extension.
  • the invention has for its object to improve a generic device in such a way that an automated assembly of all valve actuating elements with only one tool even with a relatively small space is possible.
  • extension is axially displaceable relative to the holder, and that the extension in the region of the valve spring plate has a radially inwardly directed axial stop which holds the valve actuating elements together to form an installation unit.
  • extension in the region of the valve spring plate has a radially inwardly directed axial stop which holds the valve actuating elements together to form an installation unit.
  • the extension in the region of the valve spring plate is designed to be thickened radially outwards. This makes it possible to axially support the mounting device on the cylinder head via the bead-shaped thickening. This measure allows the valve actuation elements to be released before the axial extension reaches the valve spring seat ring level in the cylinder head.
  • the mounting device When inserting the mounting device, the mounting device is supported axially on the cylinder head housing; By axially pushing into the final installation position, the axial extension from the valve spring end or valve spring seat ring is automatically released.
  • the extension is preferably in the form of a cylindrical sleeve receiving the installation unit trained and made of plastic for cost reasons.
  • FIG. 1 shows an assembly device (1) according to the invention before installation.
  • the valve actuators consist of two valve springs (2, 3), a valve spring plate (4) with a conical recess (5) for receiving segment-shaped fastening parts (6) and a spring seat ring (7), which is also used to hold a valve stem seal (8) .
  • All valve actuation elements (2, 3, 4, 6, 7, 8) are connected to one another via a holder (9) according to the invention, which has an axial extension (10).
  • the axial extension (10) has a radially inward axial stop (11) and is thickened (12) in the region of the valve spring plate (4).
  • Bracket (9) and axial extension (10) are telescopically displaceable relative to each other and form a cap for receiving all valve actuation elements (2, 3, 4, 6, 7, 8), wherein the axial stop (11) and the slightly radially inwardly bent end region (13) of the axial extension (10) are provided for axial locking.
  • FIG. 2 shows a cylinder head (14) of an internal combustion engine with an associated valve (15).
  • the mounting device (1) is inserted into a corresponding receiving bore (16) in the cylinder head (14); the bead-shaped thickening (12) is supported axially on the cylinder head (14). In this way, there is a defined distance between the end region (13) and the bottom of the receiving bore (16).
  • the end area (13) automatically detaches from the spring seat ring (7). This means that the valve actuating elements (2, 3, 4, 7, 8) are released by the mounting device (1).
  • an assembly tool presses the valve actuating elements (2 ', 3', 4 ', 6', 7, 8) into the final installation position (shown in dashed lines) so that the spring seat ring (7) is at the bottom of the receiving bore (16). is present, the fastening parts (6 ') create a connection with the valve (15), and the valve stem seal (8) is positioned on a valve guide (17). Finally, the assembly device (1) is pulled axially out of the receiving bore (16) and can be fitted with new valve actuating elements for further processing.
