Abstract
The invention discloses an oilway structure of a lubricating oil outlet of a turbocharger bearing body. The oilway structure comprises a transition oil chamber (1), a transition oil outlet pipe (2), a return oil sump oil pipe (3), an oil-gas separator (4) and a negative pressure suction pipe (5), wherein the transition oil chamber (1) is provided with an oil inlet (11) and an oil outlet (12); the oil inlet (11) of the transition oil chamber (1) is communicated with a turbocharger bearing body oil outlet (21) through the transition oil outlet pipe (2); the oil outlet (12) of the transition oil chamber (1) is communicated with an engine oil sump through the return oil sump oil pipe (3); and the air inlet port of the oil-gas separator (4) is communicated with the transition oil chamber (1), while the air outlet port of the oil-gas separator (4) is communicated with an air compressor inlet of the turbocharger. The oilway structure can prevent the lubricating oil of the turbocharger bearing body from leaking towards a pressure end and a turbine end.
Description
Technical field
The present invention relates to a kind of turbo-charger bearing body lubricant oil oil channel structures, particularly a kind of oilway structure of lubricating oil outlet of turbocharger bearing body.
Background technique
The bearing support lubricant oil of present turbosupercharger is when entering bearing support with normal pressure, and after by floating bearing and thrust bearing working surface, oil pressure is vanishing, just flows back to the oil sump of motor naturally downwards by gravity; And the wheel back of the body at turbosupercharger two ends (pressing the back of the body and the whirlpool back of the body) locates that certain gas pressure is all arranged in normal operation, so machine oil is can not flow to the high pressure district from low pressure zone; The main effect of the seal ring of turbosupercharger is that the gas of sealing in gas compressor and the turbine case leaks to the intermediate oil pocket, have only under special circumstances, oil leak just plays sealing machine oil, so the bearing support lubricant oil of present turbosupercharger generally can not take place when proper functioning.But in actual use, deform or block, cause the machine oil oil return not smooth as return line because of machine oil takes place, bearing support inner engine oil overpressure, compressor oil flows along the rotor axial two ends and extrudes seal ring and cause leakage of oil; If engine crankcase waste gas pressure surpasses specified value, pressurized machine return line internal pressure is raise simultaneously, oil return does not freely cause the seal ring leakage of oil.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art and a kind of oilway structure of lubricating oil outlet of turbocharger bearing body is provided, it can prevent the oil leak of turbo-charger bearing body.
Technological scheme of the present invention is: a kind of oilway structure of lubricating oil outlet of turbocharger bearing body, and it comprises transition oil pocket, transition oil outlet tube, oil return drain pan oil pipe and negative pressure straw; The transition oil pocket is provided with filler opening and oil outlet, and the filler opening of transition oil pocket is communicated with turbo-charger bearing body oil outlet by the transition oil outlet tube, and the oil outlet of transition oil pocket is communicated with engine sump tank by oil return drain pan oil pipe; The transition oil pocket is communicated with the turbocharger air compressor import by negative pressure straw.
The further technological scheme of the present invention is: it also comprises deaerator, and deaerator is serially connected between transition oil pocket and the negative pressure straw, and the air inlet port of deaerator is communicated with the transition oil pocket, and its suction port is communicated with negative pressure straw.
The present invention compared with prior art has following characteristics:
The present invention makes between turbo-charger bearing body oil outlet, turbocharger air compressor import and the engine sump tank and to form a kind of three-port structure, two leads to structures sample not fully than what present turbo-charger bearing body lubricating oil outlet oil circuit just formed between turbo-charger bearing body oil outlet and engine sump tank; The present invention makes the bearing support oil outlet form negative pressure, can finely avoid the oil leak of turbo-charger bearing body.
Below in conjunction with the drawings and specific embodiments detailed structure of the present invention is further described.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment
As shown in Figure 1: a kind of oilway structure of lubricating oil outlet of turbocharger bearing body, it comprises transition oil pocket 1, transition oil outlet tube 2, oil return drain pan oil pipe 3, deaerator 4 and negative pressure straw 5; Transition oil pocket 1 is provided with filler opening 11 and oil outlet 12, and the filler opening 11 of transition oil pocket 1 is communicated with turbo-charger bearing body oil outlet 21 by transition oil outlet tube 2, and the oil outlet 12 of transition oil pocket 1 is communicated with engine sump tank by oil return drain pan oil pipe 3; The air inlet port of deaerator 4 is communicated with transition oil pocket 1, its suction port is communicated with the turbocharger air compressor import by negative pressure straw 5, negative pressure-pumping effect by the turbocharger air compressor import, make bearing support oil outlet 21 form negative pressure, avoid the oil leak of turbo-charger bearing body.
The present invention is not limited to above-mentioned concrete structure, so long as the oilway structure of lubricating oil outlet of turbocharger bearing body that forms a kind of three-port structure at turbo-charger bearing body oil outlet 21, turbocharger air compressor import and engine sump tank just drops within protection scope of the present invention.
