Description
Technical field
The utility model belongs to car engine air admittance supercharging device, and in particular to a kind of vapour driven by electric motor of automobile
Vehicle air inlet boosting device.
Background technique
Currently, automobile engine supercharging device has engine driven supercharging and turbocharging two ways.
Mechanical pressurizing apparatus is typically to utilize belt by the power driven compressor work from engine crankshaft
Crank pulley is connected, booster is driven with the torsion of crankshaft operation, reaches pressurization purpose.There are problems to be: the leaf of booster
It is high to take turns shape processing cost, needs to be processed with five-axis machine tool；Not only pressurization is not helped in high engine load operation, also
Biggish loss can be caused to engine speed raising, lose more power output.
Turbo charging installation is that the turbofan in exhaust pipe is pushed to drive the whirlpool in air inlet pipe using the exhaust gas that engine generates
Fan rotation is pressurized, not the power of consumption of engine.Turbo charger speed is high, and institute's pressurized energy is also higher than mechanical supercharger
Several times are looked forward to using, become the market mainstream by most vehicles.There are problems to be: the exhaust gas turbine of booster shaft end and the pump of inlet end
It is high to take turns processing cost, needs to be processed with five-axis machine tool, the blade of turbine will use high-temperature metal；Exhaust gas turbocharge makes booster
The difficulty that the lubrication of axis becomes at high temperature, lubricating oil has carbon distribution to be formed at high temperature, influences the lubrication of floating axle；Exhaust gas turbocharge
Pressurization gas temperature is high in the process, needs intercooler cooling；The idling certain time after automobile requires driver to stop on
Stop working engine again, this requires to get higher to the driving habit of driver；The damage probability of final boost device is also higher, and the zero of replacement
Component costs and cost of labor are all high.
Summary of the invention
In order to solve the problems, such as that the prior art exists, the utility model provides a kind of automobile electricity supercharging device, passes through automobile sheet
Body motor drives the pump impeller rotation in supercharging device to realize the purpose of pressurization, this supercharging device structure is simple, overcomes automobile increasing
The high problem of depressor manufacturing cost, can be improved car engine in the case where not changing just engine displacement and engine speed
Machine power, achieves energy-saving and emission reduction purposes.
To achieve the above object, the utility model provides a kind of automobile electricity supercharging device, it is characterised in that: including motor,
Lubricating oil pump, oil pan, safety valve, booster, lubricating oil pump top oil outlet are connected to booster, and lower part oil absorbing end is passed through machine
In oily oil sump, safety valve is in parallel with lubricating oil pump；The motor is magneto, including motor stator coil, permanent magnet rotary；
The booster includes shell, is placed in the intracorporal pump impeller of shell, motor shaft, and pump impeller is connect by motor shaft with permanent magnet rotary, electricity
Be equipped with copper bush between arbor and shell, be used to support motor shaft, motor shaft both ends are equipped with oil sealing, the pump impeller end of shell be equipped with into
Port and gas outlet are equipped with oil inlet above the motor shaft position of shell, machine oil oil return opening are arranged below and leads to oil pan
It is interior.
Further, the pipeline that the lubricating oil pump leads to oil pan is equipped with filter core.
Further, the oil inlet position above the motor shaft position of the shell is right above copper bush.
Further, the pump impeller blade is plastics casting blade.
The advantages of the utility model and good effect: structure is simple, does not have to intercooler, does not have to lubrication, design and manufacture cost
It is low.Using the lubricating oil pump of fuel vehicle itself as booster power, extra power output is not needed.Motor-driven motor shaft is adopted
It is supported with copper bush, friction and noise can utmostly be reduced using force feed.The pump impeller of booster can use common material
Material production, overcomes the high problem of orthodox car booster manufacturing cost, is suitable for economical fuel oil vehicle.
