Description

Exhaust turbine-driven permanent magnet generator for vehicle
Technical field
The invention provides a kind of exhaust turbine-driven permanent magnet generator for vehicle, belong to electric motor of automobile technical field of electric appliances.
Background technology
Auto industry is the mark of modern industry, it is the leading industry of the national economic development, the various aspects of living in industrial and agricultural production, communications and transportation and human being's production all play indispensable effect, fuel in Motor Engine Cylinder combustion produce 25% ~ 40% of gross energy and be converted to Effective power, all the other 60% ~ 75% all lose, the energy that wherein waste gas is taken away is 25% ~ 35%, recycles this part exhaust energy and has important practical significance.As published patent of invention: waste gas turbine supercharged power generator, application number: 02 1 07205.1, be made up of permanent magnet and coil windings, scheme one: permanent magnet is embedded in the symmetric position of compressor impeller respectively, and the arrangement of its magnetic polarity is just contrary, and between coil windings and permanent magnet, keeping certain gap, permanent magnet and coil windings are the inner sides being fixed on compressor housings; Scheme two: permanent magnet is embedded on rotor main shaft, and coil windings is also arranged on symmetrical position respectively, keeps certain gap between permanent magnet and coil windings, coil windings is then fixed on middle casing; Scheme three: permanent magnet is embedded in the back of compressor impeller, and coil windings is fixed on the relevant position of middle casing, keeps certain gap between permanent magnet and coil windings.This technical scheme is bonded in by polylith permanent magnet on compressor impeller or on rotor main shaft or the back of compressor impeller, owing to using bonding agent adhesive permanent magnetism body, the easy ageing failure of bonding agent, poor reliability, easy damage, its serviceability needs further improvement.
Summary of the invention
The object of this invention is to provide one and can overcome above-mentioned defect, compact conformation, take up space little, the waste gas Direct driver of being discharged by engine, the exhaust turbine-driven permanent magnet generator for vehicle of energy savings, its technology contents is:
The exhaust turbine-driven permanent magnet generator for vehicle be made up of exhaust turbine, electricity generation system, permanent magnet, rotor, front end housing, rear end cap, it is characterized in that: exhaust turbine is bolted on front end of shield, the quantity of electricity generation system is equal with the quantity of permanent magnet, and by the second screw, spaced to be separately fixed in rear end cap inner chamber circumferentially same by the first screw, armature winding iron core for permanent magnet;
Electricity generation system is made up of armature winding, armature winding iron core, the second screw, armature winding is wrapped on the cylindrical of armature winding iron core, each armature winding direction of winding is consistent, equal turn numbers, the tail end of first armature winding connect second armature winding head end, the like, the head end of the tail end of last armature winding and first armature winding is as the voltage output end of exhaust turbine-driven permanent magnet generator for vehicle;
Rotor is made up of rotor disk, axle, nut, rotor disk is flange plate type structure, periphery is provided with multiple rotor pole, the quantity of rotor pole equals the quantity of permanent magnet and the quantity sum of armature winding iron core, rotor disk is fixed on axle by nut, there is certain interval between the axial direction of rotor disk and permanent magnet, armature winding iron core, can relatively rotate.
Operation principle: magnetic flux by the N pole of permanent magnet through air gap to a rotor pole again to another adjacent rotor pole, again through air gap, armature winding iron core, rear end cap to the S pole of permanent magnet, form closed-loop path, the HTHP waste gas that engine is discharged enters turbine by air inlet and drives turbine to rotate, turbine is by axle drive electrical generators rotor turns, magnetic flux in armature winding iron core constantly changes, and makes armature winding produce electromotive force, provides electric energy to vehicle power consumption equipment.
Compared with prior art, rotor is flange plate structure, has not both had electric excitation winding in the present invention, also do not have permanent magnet, structure is simple, and moment of inertia is little, excitation field is provided by permanent magnet, few without electric excitation winding, power consumption, non-carbonate slip ring structure, failure rate is low, turbine is bolted on front end of shield, compact conformation, easy for installation, the waste gas Direct driver of being discharged by engine, energy savings, emissions reduction.
