Definitions

  • the invention relates to a control drive for an internal combustion engine according to the genus Claim 1 from.
  • control drives known from US Pat. No. 4,671,223 are used to transfer the engine speed to control elements (e.g. camshafts for valve actuation) and auxiliary units (e.g. generator, pumps) and are preferred designed as belt or wheel drives.
  • the engine speed is controlled by the crankshaft and a corresponding crankshaft gear is introduced into the timing gear and there via appropriate intermediate gears or belts to the individual units to be driven forwarded or redirected.
  • the carrier unit for the gears to provide the timing drive with a backlash that compensates for backlash between the individual gears and between the carrier unit and the housing of the internal combustion engine enables.
  • the known carrier for a control drive of an internal combustion engine in particular a gear wheel drive, however, has the disadvantage that it is due to its articulation the crankshaft is difficult to fix via a ball bearing and relatively large installation space in the axial direction of the internal combustion engine is required.
  • the Backlash compensation on the mounting of the carrier on the internal combustion engine housing remote from the crankshaft by means of elastic O-rings not sufficient, especially in axial It is hardly possible to compensate for play in the direction of the fastening bolts.
  • the Permanent resilience of such O-rings especially in a position shifted from their rest position Position is insufficient and thus increases the maintenance effort due to the need Exchanges.
  • the invention is therefore based on the object, a game compensation for the attachment of Provide carrier unit of the control drive on the housing of the internal combustion engine, the adequate clearance compensation between the internal combustion engine housing and the Carrier unit enables and also over the entire life of the internal combustion engine works safely.
  • the control drive according to the invention for an internal combustion engine with the characteristic Features of claim 1 have the advantage over the prior art that that the play compensation element is designed as a hydraulic play compensation element.
  • the hydraulic function of the compensating element has the advantage that on this Almost no wear occurs and thus a reliable function over the entire service life the internal combustion engine is guaranteed.
  • the hydraulic backlash compensation also enables additionally also a damping of the vibration transmission from the internal combustion engine on the gear drive and vice versa.
  • Two hydraulic lash adjusters are preferably provided, which in advantageously at the same time as overhead fixings of the carrier unit remote from the crankshaft serve so that additional upper fasteners are dispensed with can.
  • there is a piston of the play compensation element which is axially displaceably guided in a cylinder screwed to the front of the housing of the internal combustion engine, while the cylinder, which is relatively displaceable relative to this, is fastened to the carrier unit.
  • the sealing elements between the piston and the cylinder of the play compensation element is also advantageously designed to be elastic.
  • the carrier unit preferably has two carrier plates, between which the gear wheels of the control drive are preferably arranged in one plane. These carrier plates have thereby receiving holes with which they on the outer wall surface of the cylinder Match compensation element are arranged. There are preferably two paragraphs on the Outside wall of the cylinder of the play compensation element provided, on each of which Carrier plate is fixed.
  • the carrier plates are preferably in a simple manner on the Cylinder pressed on, but can alternatively be attached differently.
  • Another advantage is the use of the play compensation elements as a bearing for Gears of the gear train, these preferably on the outer wall of the cylinder are guided in the form of a plain bearing between the two support plates, so that the Game compensation elements in addition to the function of fastening and game compensation also take over a function as gear bearing, whereby the number of components of the Wheel drive and thus its weight can be reduced.
  • Lubrication on the Cylinders of the play-compensating gears are advantageously carried out Way through lubrication holes in the wall of the pistons and cylinders. These holes will be analogous to the hydraulic work rooms of the play compensation elements from the central Lubricant circuit of the internal combustion engine is supplied with, so that no additional supply circuit is required for the hydraulic lash adjusters.
  • Figure 1 shows a control drive for an internal combustion engine, the rotational movement of the Crankshaft to the individual control elements in a known manner, e.g. Valve camshaft and Auxiliary units, e.g. Pumps, the internal combustion engine transmits and in the embodiment is designed as a pure gear train.
  • the control drive has a carrier unit 1, which consists of two opposite carrier plates 3, between which gears, e.g. 5, on a common level are arranged and stored.
  • the carrier unit 1 has a circular recess 7 in its lower region, in which protrudes a gear arranged on the crankshaft, not shown, which with a Intermediate gear 9 of the timing gear meshes and thus rotates in a known manner drives.
  • the carrier unit 1 is in the area near the crankshaft below in the exemplary embodiment three holes 11 in the carrier plates 3 with the housing of the internal combustion engine screwed.
  • the carrier unit 1 In the area remote from the crankshaft, the carrier unit 1 is at the play compensation elements 13 Fixed housing of the internal combustion engine, which is shown in more detail in Figures 2 and 3 are.
  • the work spaces 21 and 23 are one formed as a calibration bore overflow channel 25 connected to each other Flow cross-section the sensitivity and the degree of play compensation and the Have damping set.
  • the pressure medium is supplied in a manner not shown Way via a connection to the lubricating oil circuit of the internal combustion engine.
  • the hydraulic play compensation elements 13 are connected to the housing via the piston 17 connected to the internal combustion engine, for which purpose a screw, not shown, on the piston 17 protrudes through a central through hole 27.
  • the screw lies with her head on an end 29 of the piston 17 facing away from the motor housing and engages with it free end into a corresponding mounting hole in the motor housing.
  • the cylinder 15 of the play compensation elements 13 is connected to the carrier unit 1, for which purpose the carrier plates 3 via corresponding receiving openings on the outer wall surface of the Cylinder 15 are pushed on, preferably pressed on.
  • the cylinder 15 instructs its outer wall has two shoulders 31, which push and push the two opposite Support carrier plates 3 on the cylinder 15.
  • the outer wall surfaces of the cylinder 15 also form bearing surfaces for at least one Gear 33 of the timing gear drive of the internal combustion engine, this bearing as a plain bearing is formed, which has a supply bore 35 in the piston 17 and in the cylinder 15 is supplied with lubricant.
  • the axial play compensation between the carrier unit 1 and the internal combustion engine housing takes place via a relative movement between piston 17 and cylinder 15, wherein the oil in each case from one of the working spaces 21, 23 via the overflow channel 25 into the other work space 21, 23 is displaced.
  • a setting of the response times and response tolerances of the hydraulic lash adjuster 13 can be the Set the diameter of the overflow channel 25.
  • the elastic sealing elements also allow one through their compression Compensation for play in the radial direction and when the components tilt towards one another, so that no additional components are required for this.
