Abstract

The utility model provides a turbocharger intermediate body with a filter function, which belongs to the field of accessories of turbochargers of engines. The intermediate body is provided with a main oil supply hole, the main oil supply hole is communicated with an oil supply hole of a thrust bearing, the oil supply hole of the thrust bearing is communicated with a first oil return hole successively through an oil supply hole of a floating bearing and a floating bearing support frame provided with the floating bearing, and the intermediate body is further provided with an impeller shaft hole sealing ring fixing seat communicated with the first oil return hole. The turbocharger intermediate body is characterized in that a filter screen is disposed in the oil supply hole of the thrust bearing of the intermediate body. Compared with the prior art, the turbocharger intermediate body with the filter function can filter impurities in oil of an engine as the filter screen is arranged in the oil supply hole of the thrust bearing of the turbocharger intermediate body, and can avoid blocking the thrust bearing of the turbocharger, thereby effectively preventing an impeller of a turbocharger from deviating, preventing burning of the thrust bearing due to the fact that the thrust bearing is not lubricated by oil, not only prolonging the service life of the turbocharger and reducing use cost better, but also decreasing possibility that power of the engine is reduced due to reduction of rotation speed of the turbocharger.

Description

A kind of turbosupercharger intermediate with the filtering function

(1) technical field

The utility model relates to a kind of accessory of engine turbine pressurized machine, specifically a kind of turbosupercharger intermediate with the filtering function.

(2) background technique

Along with the more and more stricter propelling of vehicular discharge rules, make the supercharging technology widespread usage on vehicle.Turbosupercharger is that the turbine that the high-temp waste gas that utilizes motor to discharge blows pressurized machine runs up, run up thereby drive with the coaxial compressor impeller of turbine, the pressurized air that compressor impeller produces offers motor again, makes the air inlet of motor become pressure air by natural aspiration.Because the air quantity that provides increases, the motor more fuel that can burn makes burning also more simultaneously, and the turbosupercharger power of consumption of engine not, so turbosupercharger also is exhaust-gas turbocharger.After motor uses turbosupercharger, can improve the power per liter of motor greatly, reduce fuel consumption rate, improve the discharging of motor, turbosupercharger is the new high-tech product of energy-saving and environmental protection.

Thrust bearing of turbocharger is a vitals of turbosupercharger, at present, owing to do not have device for filtering impurities on the thrust bearing of turbocharger, turbosupercharger is after operation a period of time, owing to reason such as engine motor oil is dirty, the thrust bearing of turbocharger blocking phenomenon can take place cause thrust bearing of turbocharger oil-free lubrication scaling loss and supercharger impeller sideslip, reduce supercharger speed and make engine power descend.

(3) summary of the invention

Technical assignment of the present utility model is at the deficiencies in the prior art, provide a kind of and can solve the thrust bearing of turbocharger blockage problem, thereby prevent that thrust bearing of turbocharger oil-free lubrication scaling loss and impeller sideslip from reducing supercharger speed and making the turbosupercharger intermediate of the band filtering function that engine power descends.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of turbosupercharger intermediate with the filtering function, comprise intermediate, offer main oil supply hole on the intermediate, main oil supply hole communicates with the thrust bearing oil supply hole, the thrust bearing oil supply hole communicates with first spill port by the floating bearing oil supply hole with after the floating bearing supporting frame of floating bearing is set successively, on intermediate, also be provided with the impeller axis hole seal ring fixed base that communicates with first spill port, in the thrust bearing oil supply hole of intermediate, be provided with filter screen.

The turbosupercharger intermediate of above-mentioned band filtering function, the axis of its main oil supply hole and first spill port is on same direction, the axis of impeller axis hole seal ring fixed base and floating bearing supporting frame on same direction, the above-mentioned main oil supply hole and first spill port towards with impeller axis hole seal ring fixed base and floating bearing supporting frame towards mutually vertical.

The engine motor oil oil pump feed, supply with the turbosupercharger intermediate by oil duct and oil pipe, thrust bearing oil supply hole by the pressurized machine intermediate is supplied with booster thrust bearing produced, be that lubricant oil flows to thrust bearing behind the net filtration earlier after filtration again, after thrust bearing and thrust plate be lubricated, be back to return tube through spill port again, be back to oil sump through return tube.

The turbosupercharger intermediate of band filtering function of the present utility model compared with prior art, the beneficial effect that is produced is: owing to be provided with filter screen in the thrust bearing oil supply hole of turbosupercharger intermediate, so can filter out the impurity in the engine motor oil, thrust bearing of turbocharger is stopped up, thereby prevented the generation of turbo-charger impeller sideslip and thrust bearing oil-free lubrication burning phenomenon effectively, not only improve the working life of turbosupercharger, better reduced user cost; Also reduce turbo charger speed and reduced the generation probability that makes that engine power descends.

(5) embodiment

Below in conjunction with explaining below the turbosupercharger intermediate work of accompanying drawing 1-3 to band filtering function of the present utility model.

Shown in accompanying drawing 1-3, a kind of turbosupercharger intermediate of the present utility model with the filtering function, its structure comprises intermediate 1, offer main oil supply hole 2 on the intermediate 1, main oil supply hole 2 communicates with thrust bearing oil supply hole 7, thrust bearing oil supply hole 7 communicates with first spill port 3 by floating bearing oil supply hole 9 and floating bearing supporting frame 5 backs that floating bearing is set successively, also be provided with the impeller axis hole seal ring fixed base 4 that communicates with first spill port 3 on intermediate 1, its innovative point is to be provided with filter screen 8 in the thrust bearing oil supply hole 7 of intermediate 1.

The axis of the above-mentioned main oil supply hole 2 and first spill port 3 is on same direction, the axis of impeller axis hole seal ring fixed base 4 and floating bearing supporting frame 5 on same direction, the above-mentioned main oil supply hole 2 and first spill port 3 towards with impeller axis hole seal ring fixed base 4 and floating bearing supporting frame 5 towards mutually vertical.
