Definitions

  • the invention relates to an exhaust-gas turbocharger according to the preamble of claim 1.
  • An exhaust-gas turbocharger of said type is known from EP 2 054 597 Bl.
  • said exhaust-gas turbocharger For the supply of lubricant to the bearings of the shaft, said exhaust-gas turbocharger utilizes the engine oil pump of the internal combustion engine on which the turbocharger is mounted.
  • the described problems can, in extreme applications such as for example in hybrid applications or a very high number of start/stop cycles, lead to damage to the bearing arrangement of the exhaust-gas turbocharger and therefore to failure of the overall system.
  • an additional oil accumulator is provided which, in said document, is referred to as an emergency oil tank and extends in the axial direction over all the radial bearings. Since gravitational force is used to provide an oil supply in said system, the emergency oil tank is arranged above the radial bearings and at a small radial distance from said bearings.
  • the additional oil accumulator of the exhaust-gas turbo charger according to the invention is designed as a pressure accumulator.
  • lubricant is supplied in a dosed fashion to the bearing arrangement thereof by means of said pressure accumulator.
  • a partial quantity of the lubricant in circulation is extracted and temporarily stored in the pressure accumulator as pressurized lubricant.
  • a hydraulic accumulator such as is known from the field of hydraulics.
  • lubricant By means of a controllable valve on the pressure accumulator and preferably a further simple check valve in the inflow line for the lubricant, it is possible for lubricant to be supplied in a dosed fashion to the bearing arrangements during the starting and stopping of the engine.
  • check valve in the inflow line it is possible here for the check valve in the inflow line to be exchanged for a controllable valve, in particular check valve, or a pressure differential valve.
  • a pressure differential valve If a pressure differential valve is used, the pressures on both sides of the valve are utilized to generate a movement of the valve in order to realize a build-up or dissipation of pressure in the inflow line and/or in the pressure accumulator and during start/stop cycles.
  • controllable valve in particular check valve
  • the pressure signals of the inflow line and of the accumulator system are evaluated and linked by means of an actuation strategy in such a way that a uniform pressure build-up takes place in the bearing system.
  • the system prefferably designed as an external or internal system.
  • Figure 1 shows a perspective, cut-away illustration of an exhaust-gas turbocharger showing the basic components not illustrated in Figure 2, and
  • Figure 2 shows a schematically simplified illustration of an exhaust-gas turbocharger according to the invention.
  • An exhaust-gas turbocharger 1 according to the invention illustrated in Figure 2 has not only the components illustrated in said figure but also the components shown in Figure 1, specifically a shaft 2, a compressor wheel 3, a turbine wheel 4 and a bearing housing 5.
  • a compressor-side bearing arrangement 6 and a turbine-side bearing arrangement 7 for mounting the shaft 2 are arranged in the bearing housing 5.
  • the exhaust-gas turbocharger 1 according to the invention self-evidently also has all the other conventional components of modern turbochargers, but these are not of importance for the description of the present invention.
  • the exhaust-gas turbocharger 1 also has an oil inflow line 8 and an oil outflow line 9 which are hydraulically connected to the engine oil circuit of the engine on which the exhaust-gas turbocharger 1 is mounted.
  • the exhaust-gas turbocharger 1 also has an additional oil accumulator 10 which is designed as a pressure accumulator and arranged in a branch line 11 of the oil inflow line 8.
  • a controllable valve 13 is inserted between the oil accumulator 10 and the opening- in point 12 of the branch line 1 1 into the oil inflow line 8.
  • the controllable valve 13 can be opened and closed by means of a control device 14, wherein the control device 14 for this purpose uses pressure signals from the inflow line and from the pressure accumulator 10, said pressure signals being symbolized in Figure 2 by the dashed line DS.
  • a simple check valve 15 which may also be replaced with a controllable valve.
  • the pressure accumulator 10 can be charged with pressurized lubricant when sufficient oil pressure has been built up by the oil pump of the engine.
