Description
Technical field
The utility model relates to a kind of exhaust-gas turbocharger, especially relates to a kind of filler opening flow passage structure of exhaust-gas turbocharger.
Background technique
Operationally, turbine rotor High Rotation Speed, floating bearing inside and outside footpath place's moment will have extreme pressure lubricant to lubricate to exhaust-gas turbocharger, otherwise pressurized machine will wear out failure within the extremely short time.So the matching gap of floating bearing and turbine rotor and middle case is very little, be 0.11mm with the gap of middle case, with the gap 0.06mm of turbine rotor, be beneficial to the high pressure forming lubricant oil, large flow velocity, to reach lubrication, to absorb the object of heat.Lubricant oil utilizes self gravitation after terminating lubrication, heat-absorbing action, simultaneously by the seal action of seal ring, the stop of turbine rotor sidewall, flows back to engine oil tank by drain pan, to reach the object that lubrication oil circulation utilizes.As shown in Figure 1, be the structure of traditional oil duct, the iron filings of boring generation like this, exist bottom main oil gallery, washing machine is difficult to clean out, and can cause fatal harm like this to pressurized machine quality.
Model utility content
Technical problem to be solved in the utility model is: the filler opening flow passage structure providing a kind of exhaust-gas turbocharger, dead angle is not had between second oil inlet passage and the 4th branch's oil inlet passage, iron filings are directly discharged from the second oil inlet passage by the 4th branch's oil inlet passage, can realize the object of clearing up iron filings.
For solving the problems of the technologies described above, the technical solution of the utility model is: the filler opening flow passage structure of exhaust-gas turbocharger, comprise be arranged at described exhaust-gas turbocharger intermediate on the first oil inlet passage, second oil inlet passage and the 3rd branch's oil inlet passage and the 4th branch's oil inlet passage, described first oil inlet passage is connected with described second oil inlet passage, and the tie point of described first oil inlet passage and the second oil inlet passage is positioned at the middle part of described second oil inlet passage, described 3rd branch's oil inlet passage is all connected with described second oil inlet passage with the 4th branch's oil inlet passage, the tie point of described 3rd branch's oil inlet passage and the second oil inlet passage is positioned at the middle part of described second oil inlet passage, the tie point of described 4th branch's oil inlet passage and the second oil inlet passage is positioned at the end of described second oil inlet passage, described 3rd branch's oil inlet passage is corresponding with the first floating bearing position of described exhaust-gas turbocharger, described 4th branch's oil inlet passage is corresponding with the second floating bearing position of described exhaust-gas turbocharger.
Preferably, described first oil inlet passage is vertically arranged, and described second oil inlet passage is horizontally disposed with.
Preferably, described 3rd branch's oil inlet passage and the 4th branch's oil inlet passage is equal and be provided with angle between described second oil inlet passage, in splayed configuration arranged between described 3rd branch's oil inlet passage and the 4th branch's oil inlet passage.
Have employed technique scheme, the beneficial effects of the utility model are: the filler opening flow passage structure of exhaust-gas turbocharger of the present utility model, dead angle is not had between second oil inlet passage and the 4th branch's oil inlet passage, iron filings are directly discharged from the second oil inlet passage by the 4th branch's oil inlet passage, can realize the object of clearing up iron filings.
