The lubrication device comprises a tank body, a spring, a middle partition board and sealing rings, wherein the piston type middle partition board is arranged in the tank body; the sealing rings are fixed at the two ends of the middle partition board; the middle partition board divides the tank body into two cavities, the resetting spring is arranged in one cavity, and the other cavity is an oil storage cavity; the two ends of the spring are fixed on the top of the tank body and the upper end of the middle partition board respectively; a limiting structure for the spring is arranged on the top of the tank body; and an engine oil inlet is formed on a wall at one end of the oil storage cavity, and is connected with an oil inlet pipeline for the lubrication of the supercharger. After the lubrication device is arranged on the exhaust driven supercharger, when an engine is in a suddenly stopped state, the exhaust driven supercharger in an inertial running state can well be lubricated by engine oil and cooled, so that the phenomenon of seizure between a shaft and a shaft sleeve of the supercharger and the phenomenon of carbon deposit formed by a part of engine oil are avoided, the failure rate of the exhaust driven supercharger is lowered, and the number of maintenance times is decreased.
Description
Technical field
The utility model belongs to the engine booster technical field, relates to the lubricating fitting of exhaust-gas turbocharger in a kind of motor.
Background technique
Along with development in science and technology and social progress; Automobile has become the indispensable traffic tool in people's life; Advocate under the overall situation of energy-saving and emission-reduction and environmental protection in country simultaneously, in today that the vehicle fuel price rises steadily, automobile with small output volumn receives more and more Consumers' favor always.Pursuing little discharge capacity the Consumer has impelled the small displacement engine of band exhaust-gas turbocharger to become the first-selection of automobile factory with purchasing of better power character under the car theory.The engine power and the moment of torsion that install additional behind the exhaust-gas turbocharger can increase 20%-30%.
Exhaust-gas turbocharger is installed in engine exhaust one side; So the operating temperature of pressurized machine is very high, and the rotating speed of pressurized machine rotor when work is very high, can reach per minute tens0000 commentaries on classics; So high rotating speed and temperature makes common mechanical needle roller or ball bearing can't be working rotor; Therefore exhaust-gas turbocharger generally adopts floating bearing, be lubricated by machine oil, and to do cooling liquid by machine oil is that pressurized machine cools off.After the automobile of band exhaust gas turbocharge runs up for a long time, can not stop working immediately.Because some engine oil supplying turbocharger rotor bearing lubrication and turbosupercharger cooled off during engine operation; The motor that is moving is shut down the back engine oil pressure suddenly and is dropped to zero rapidly; The oil lubricating of turbosupercharger can interrupt; The inner heat of turbosupercharger also can't be taken away by machine oil; At this moment the high temperature of booster turbine part can pass in bearing and the support shell, and supercharger rotor is still running up under effect of inertia simultaneously, will cause like this to occur killing phenomenon between turbocharger shaft and the axle sleeve.Thereby damage pressurized machine.
After motor stopped working suddenly in addition, the temperature of gas exhaust manifold was very high, and its heat can be delivered to turbosupercharger inside, was boiled into carbon distribution with resting on the inner part machine oil of turbosupercharger, will block the wearing and tearing that filler opening causes turbosupercharger when carbon distribution is more and more.
The model utility content
The purpose of the utility model is exactly to solve the problems referred to above that exist in the existing technology; A kind of lubricating fitting of exhaust-gas turbocharger is provided; Adopt the exhaust-gas turbocharger of this lubricating fitting, it can guarantee that continuation is lubricated exhaust-gas turbocharger and cools off after motor is suddenly flame-out.
For realizing above-mentioned purpose, the technical solution of the utility model is: a kind of lubricating fitting of exhaust-gas turbocharger, and it comprises tank body, spring, intermediate clapboard and seal ring; The piston type intermediate clapboard is arranged in the tank body, and the intermediate clapboard two ends are fixed with seal ring; Intermediate clapboard is divided into two chambeies with tank body, in the chamber Returnning spring is arranged, and another chamber is a shoe cream room; Both ends of the spring is separately fixed at the upper end of tank body top and intermediate clapboard, and the limit structure of spring is arranged at the tank body top, organic oil import on the wall of shoe cream room one end, and the machine oil import is connected with the lubricated in-line of pressurized machine.
The limit structure of the spring at above-mentioned described tank body top has the limit casing A of spring for the tank body top, and the inwall of limit casing A and tank body is structure as a whole, and between itself and the inner tank wall cavity is arranged; The intermediate clapboard upper end has boss, both ends of the spring to be separately fixed on the boss of tank body top and intermediate clapboard upper end.
The limit structure of the spring at above-mentioned described tank body top is limit casing B, and the intermediate clapboard upper end has the spring spindle that is complementary with limit casing B inwall, both ends of the spring to be separately fixed on the spring spindle of tank body top and intermediate clapboard upper end.
The limit structure of the spring at above-mentioned described tank body top is spacing cannula C; The inwall of limit casing C and tank body is structure as a whole; The intermediate clapboard upper end has the spring spindle that is complementary with limit casing C inwall, both ends of the spring to be separately fixed on the spring spindle of tank body top and intermediate clapboard upper end.
When motor is under the operating condition; Because of the machine oil import of this lubricating fitting is connected with the lubricated in-line of pressurized machine; The machine oil of motor under the pressure of oil pump in the entering exhaust-gas turbocharger in, also some flows in the shoe cream room of this lubricating fitting, pressure spring; Behind the Spring balanced of pressure and spring, the reserves of machine oil keep.When motor was shut down suddenly, the oil pump of motor can quit work moment, caused engine oil pressure to be reduced to zero in a short period of time, lubricated will the termination of the pressurized machine of oil pump supply at this moment.Machine oil in this lubricating fitting shoe cream room has lost ambient pressure at this moment; Intermediate clapboard moves under the reseat pressure of spring; Machine oil in the shoe cream room is released and is pressed in the pressurized machine lubricating pipe; Continuation is lubricated pressurized machine and cools off, and shuts down up to supercharger rotor, and at this moment spring of this lubricating fitting and intermediate clapboard reset.
After on the exhaust-gas turbocharger this lubricating fitting being installed; When motor is in unexpected outage state; Exhaust-gas turbocharger under the coasting state can also well obtain the lubricated and cooling of machine oil; The generation that phenomenon and part machine oil are boiled into the phenomenon of carbon distribution is killed in the axle of having avoided pressurized machine and axle sleeve centre, has reduced the rate of breakdown of exhaust-gas turbocharger, has reduced maintenance frequency.Simple in structure, the low cost of manufacture of the utility model, highly versatile can be installed on the exhaust-gas turbocharger of any model and shape.
