Description
Technical field
The present invention relates to technical field of automobile accessories, more particularly, to a kind of automobile auxiliary air by exhaust gas drive
Pump.
Background technology
Secondary air pump is when engine works, and is passed through amount and the relatively low air stream of pressure greatly by air pump operating
Flexible pipe is sent into flow divider.Under normal circumstances, valve opening on flow divider, air flow through flow divider, the injection of check valve air inlet
Manifold.Its effect is：Hc, co that air-injection manifold sprays into air stream in engine exhaust hole or exhaust manifold, with exhaust
Reaction, makes it be further converted into co2 and vapor, to reduce exhaust pollution.
Automobile secondary air pump of the prior art is driven by motor, so as to need to consume storage battery on automobile
Electricity, the loss to storage battery is very big, if it is possible to drive air pump to be operated using Automobile drive power, then can be effective
Solution this problem, but also more economical technical ability, improve the service life of automobile storage battery.
The content of the invention
To solve the above problems, the present invention propose it is a kind of provide driving power without storage battery, using effect is good, can it is logical
Cross the automobile secondary air pump of exhaust gas drive.
The technical solution adopted in the present invention is：A kind of automobile secondary air pump by exhaust gas drive, including the pump housing, drive
Movable vane wheel, power transmission shaft, intake air impeller and air inlet pipeline, the side of the pump housing are provided with driving chamber, and opposite side is provided with air intake
Room, the front and back end of driving chamber have the connector being connected with gas exhaust piping, and the driving impeller is arranged on driving by power transmission shaft
Intracavitary, the other end of power transmission shaft extend to inlet air plenum, and the intake air impeller is arranged on the other end of power transmission shaft, the air inlet pipeline
It is connected with the air outlet of inlet air plenum, the other end of air inlet pipeline is provided with the connector for being used for being connected with gas exhaust piping.
Further, unidirectional mechanical valve is additionally provided with the air inlet pipeline.
Further, the drive chamber of the pump housing and inlet air plenum are not connected, and the power transmission shaft is worn by rolling bearing
Between drive chamber and inlet air plenum.
Compared with prior art, it has the advantages that the present invention：
The automobile secondary air pump by exhaust gas drive of the present invention is driven by the exhaust gas drive power on automobile exhaust pipe
Dynamic wheel rotation is so as to realize air-supply effect, and without using automobile storage battery power supply, effectively reduce storage battery uses load, carries
The high utilization rate of waste gas, more economical energy-conservation, using effect are very good.

The present invention operation principle be：The driving chamber 6 of the pump housing 1 of body is connected on the gas exhaust piping of automobile, Ran Houtong
The exhaust for crossing automobile drives driving impeller 2 to rotate, and so as to drive intake air impeller 4 to rotate, intake air impeller 4 drives the wind of institute's inspiration to lead to
Cross air inlet pipeline and be transported to automobile manifold, when automobile exhaust amount more then, the rotational efficienty of impeller is also higher, and intake is also got over
Greatly.
What the automobile secondary air pump by exhaust gas drive of the present invention was mainly told about is by the row on automobile exhaust pipe
Gas drive power drives wheel rotation so as to realize air-supply effect, without using automobile storage battery power supply, effectively reduces storage battery
Use load, improve the utilization rate of waste gas, more economical energy-conservation, using effect is very good.
