Definitions

  • the invention relates to a drive arrangement for auxiliary units of internal combustion engines of the type according to the preamble of claim 1.
  • the lubricating oil gear pump is driven via a reduction gear by a PTO shaft rotating at crankshaft speed.
  • the larger gear of the reduction gear is arranged on the common shaft of the pumps, which carries the driving pump wheel of the lubricating oil gear pump and the pump impeller of the coolant pump.
  • the reduction gear requires friction, space in the housing of the internal combustion engine and increases the weight and the manufacturing effort.
  • the invention is based on the object, in a drive arrangement according to the preamble of claim 1, to design the drive connection for the lubricating oil gear pump and the coolant pump while maintaining a reduction for the coolant pump in a space-saving, simple and weight-saving and cost-effective manner.
  • the invention solves this problem by the characterizing features of claim 1.
  • the design according to the invention achieves a very compact drive connection for the lubricating oil gear pump and the coolant pump.
  • Embodiments and developments of the invention are characterized in claims 2 and 3.
  • the features of claim 2 form a preassembled pump unit that can be easily attached to the housing of an internal combustion engine and enables simple machining of the connection surfaces on the housing of the internal combustion engine and on the pump housing.
  • Claim 3 uses the space required by the axial space requirement of the seal between the lubricating oil and coolant pump for the space-saving arrangement of the suction space of the coolant pump.
  • a pump housing 3 is attached with its mounting surface 4 to a connection surface 1 of a housing part 2 of an internal combustion engine (not shown further).
  • the end is formed by a housing cover 11.
  • the driving pump wheel 6 of the lubricating oil Gear pump 8 has a smaller number of teeth than the driven pump wheel 7.
  • the pump wheels 6 and 7 form a reduction gear for the coolant pump 9.
  • the driving pump wheel 6 is fixed in a rotationally fixed manner on a shaft 12 mounted in the pump housing 3.
  • the shaft 12 is arranged coaxially to a power take-off shaft 13 of the internal combustion engine and drive-connected to the power take-off shaft 13 via a plug-in coupling 14.
  • the driven pump wheel 7 of the lubricating oil gear pump 8 and the pump impeller 10 of the coolant pump 9 are arranged on a common pump shaft 15.
  • the pump shaft 15 is mounted in the pump housing 3 and in the housing part 2.
  • a first seal 16, a leak discharge space 17 and a second seal 18 are arranged between the pump wheel 7 and the pump impeller 10.
  • a leak discharge channel 19 leads from the leak discharge space 17 into the open.
  • An approximately annular suction space 20 of the coolant pump 9 surrounds the seals 16 and 18 and the annular space 17 at a distance and is designed to be helical in its axial extent.
  • the lubricating oil gear pump 8 and the coolant pump 9 can be preassembled as a common pump unit, so that the assembly with the housing part 2 is simplified.
  • the suction chamber 20 of the coolant pump 9 saves space between the driven pump wheel 7 Lubricating oil gear pump 8 and the pump impeller 10 of the coolant pump 9 arranged and uses the radially outer part of the space between these two wheels, which must be provided due to the seals 16 and 18 and the leakage discharge space 17.
