Definitions

  • the invention relates according to the preamble of claim 1, a coolant pump assembly for a camshaft comprehensive engine of a motor vehicle having a pump housing and a pump shaft with a pump impeller end arranged.
  • Such a water pump arrangement shows and describes, for example, the DE 199 41 891 A1 according to which the water pump has a pump housing formed of a pump body and a pump cover, which is connected to the crankcase of the internal combustion engine.
  • the pump shaft is accommodated and rotatably mounted in a shaft support section.
  • the Wellenstützanites in this case has one three times the pump shaft diameter corresponding length and is lubricated oil for lubrication, wherein the lubricating oil is supplied by means of an oil feed opening from the crankcase.
  • a seal is then axially provided on the shaft support portion.
  • This water pump assembly builds due to the pump shaft support and additionally due to the axially subsequent to this seal very long, which can be disadvantageous especially when using the internal combustion engine in a motorcycle depending on the installation position.
  • long coolant hoses are required to connect the water pump.
  • the invention is therefore the object of an initially mentioned coolant pump assembly with respect to a compact, short-built internal combustion engine, in particular for use in a motorcycle, at the same time simple and easy to maintain construction, educate.
  • the object is achieved by the features of claim 1, wherein the underlying idea comprises the substantially flying bearing of the pump shaft by means of a angeord Neten within the engine bearing.
  • the bearing is arranged inside the internal combustion engine in the cylinder head or in the crankcase.
  • the pump shaft is non-rotatable and coaxial with a driving them. Camshaft connected.
  • the water pump speed and thus the pump power are so directly dependent on the engine speed, the pump shaft according to another embodiment, the middle or directly from another motor shaft can be driven.
  • the pump shaft is supported by means of the last camshaft bearing arranged adjacently to the pump arrangement.
  • the last camshaft bearing is at the same time a bearing element for the pump shaft carrying the pump impeller.
  • a seal in particular a mechanical seal
  • the mechanical seal is designed like a pipe section and seals with its radially inner surface against the pump shaft. With its radially outer surface, the seal is supported on the inner radius of a receptacle on the pump housing on the one hand and centering on the inner radius of a receptacle on the crankcase on the other.
  • the pump shaft is hollow and the camshaft has a thread at its end.
  • the pump shaft is centered on the camshaft inside or outside.
  • FIG. 1 shows a coolant pump assembly 100 for an internal combustion engine of a motor vehicle, not shown here, in this case a four-cylinder in-line engine for a motorcycle.
  • the coolant pump arrangement 100 is connected to the front side of the cylinder head 102 of the internal combustion engine, wherein the internal combustion engine is installed transversely to the direction of travel, so that the individual cylinders are inclined side by side with the head obliquely forward. In the direction of travel, the coolant pump arrangement 100 is accordingly arranged to the left.
  • the filling of the cylinder takes place through inlet ports 150, 152, 154, 156 from above, while the combustion exhaust gases are discharged obliquely downwards / forwards; Accordingly, the intake camshaft for actuating the intake valves 158, 160, 162, 164 is up.
  • the coolant pump arrangement 100 comprises an intake stub 168 through which coolant, for example cooling water, is drawn via the thermostat 166 of the radiator 170.
  • the coolant is supplied to the water jacket, with a division of the coolant flow into a main flow for cooling the cylinder head 102 and a partial flow for cooling the crankcase. If cooling of the internal combustion engine, for example, during the warm-up phase, (still) is not required, the coolant flows in accordance with a flow control due to the thermostat position bypassing the radiator 170 directly via the short-circuit pipe 174 back to the suction nozzle 168. Only when a predetermined temperature is reached that Thermostat 166 from the short-circuit current, so that the suction nozzle 168 is acted upon by the inclusion of the cooler 170 via the line 176.
  • FIG. 2 A detailed view of a coolant pump arrangement 200 for an internal combustion engine of a motor vehicle is with FIG. 2 shown in section.
  • the coolant pump arrangement 200 is connected to the front side of the cylinder head 202 of the internal combustion engine and sucks through a suction nozzle 222 to coolant, the pressure side of the radial pump is denoted by 226.
  • the camshaft 202 comprises the cylinder head shell-like bearings, which receive the camshafts. The bearings are closed by means not shown bearing bridges.
  • the end last, the cam 224 adjacent bearing 220 of the intake camshaft 204 is shown.
  • the coolant pump shaft 206 Coaxially with the camshaft 204, the coolant pump shaft 206 is connected. A screw through the hollow coolant pump shaft 206 in a thread 228 at the camshaft end ensures a frictional connection between pump impeller 218, pump shaft 206 and camshaft 204. Centering of the pump shaft 206 takes place on the inside or alternatively on the outside of the camshaft.
  • the Coolant pump housing 214 is provided with a standard pressed-in mechanical seal 212 and bolted to cylinder head 202, the housing of mechanical seal 212 being for centering on the camshaft bearing axis in cylinder head 202. To the coolant pump housing 214, the coolant pump cover 216 is connected. The cylinder-head-side oil-tightness is achieved by means of a pressed between coolant pump bearing cap 210 and cylinder head 202 shaft seal 208.
  • the cam 224 adjacent bearing 220 of the intake camshaft 204 is also a bearing element for the cantilevered pump shaft 206, which carries the pump impeller 218.
  • a separate storage of the pump shaft 206 is thus unnecessary, so that the overall length of the internal combustion engine can be significantly reduced. This is a significant improvement, especially in the case of a four-cylinder in-line installed in a motorcycle. Due to the compact dimensions and the associated low projection area in the direction of travel, special advantages with regard to aerodynamics, fuel consumption, acceleration and top speed result. Furthermore, required space, weight and cost are reduced.
