Description
Technical field
The present invention relates to technical field of automobile, especially relate to a kind of automobile auxiliary air by exhaust gas drive
Pump.
Background technology
Secondary air pump is when electromotor works, and is passed through by the air pump operating air stream that pressure is relatively low by amount is big
Flow divider sent into by flexible pipe.Under normal circumstances, valve opening on flow divider, air flows through flow divider, and check valve enters air injection
Manifold.Its effect is: air stream is sprayed into hc, the co in engine exhaust hole or exhaust manifold, with aerofluxus by air-injection manifold
Reaction so that it is be further converted into co2 and steam, to reduce exhaust pollution.
Automobile secondary air pump of the prior art is all to be driven by motor, thus needs to consume storage battery on automobile
Electricity, the loss to storage battery is the biggest, if it is possible to utilize Automobile drive power to drive air pump to operate, then can be effective
This problem of solution, but also more economically technical ability, improve the service life of automobile storage battery.
Summary of the invention
For solving the problems referred to above, the present invention proposes a kind of offer without storage battery and drives power supply, and using effect is good, can 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, drives
Movable vane wheel, power transmission shaft, intake air impeller and air inlet pipeline, the side of the described pump housing is provided with driving chamber, and opposite side is provided with air intake
Room, before and after driving chamber, end has the union joint being connected with gas exhaust piping, and described driving impeller is arranged on driving by power transmission shaft
Intracavity, the other end of power transmission shaft extends to inlet air plenum, and described intake air impeller is arranged on the other end of power transmission shaft, described air inlet pipeline
Being connected with the air outlet of inlet air plenum, the other end of air inlet pipeline is provided with the union joint for being connected with gas exhaust piping.
Further, described air inlet pipeline is additionally provided with unidirectional mechanical valve.
Further, the drive chamber of the described pump housing is not connected with inlet air plenum, and described 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 present invention is driven by the exhaust gas drive power on automobile exhaust pipe by the automobile secondary air pump of exhaust gas drive
Move wheel rotation thus realize effect of blowing, it is not necessary to use automobile storage battery power supply, effectively reduce the use load of storage battery, carry
The high utilization rate of waste gas, the most energy-conservation, using effect is the best.
