Hyundai Motor vehicle mounted electrical apparatus electronic equipment is more and more, amount of power supply to automobile requires also increasing, current vortex retarder work meeting further strengthens the requirement to battery capacity, will certainly make automobile increase engine and generator capacity like this, has increased the fuel consume of automobile; Simultaneously, because the heating of stator itself and be subjected to the influence of rotor temperature rise all is subjected to its stopping power and service time certain restriction, this is just to the exciting current and the very high requirement of radiating effect proposition of retarder.In order to reduce the dependence of current vortex retarder for the automobile power system power supply, the self-excitation retarder that has occurred having spontaneous electrical function and need not increase or strengthen automobile current generator capacity and battery capacity.The patent No. is that ZL200520018917.0, name are called " self power generation eddy current retarder " and the patent No. is that ZL200520075634.X, name are called " self-excitation type current vortex retarder ".The defective of these two patents is: all adopt natural air cooled mode, can not distribute the heat that produces on the retarder vortex induction body effectively, the time of having limited the raising of self-excitation retarder braking moment and having continued to brake.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, propose a kind of self-excitation retarder, adopt the water-cooling pattern structure, solved the heat radiation bottleneck problem of former self-excitation retarder, prolonged lasting braking time with water-cooling system; Improve the air gap flux density of Blast Furnace Top Gas Recovery Turbine Unit (TRT), improve the intensity of auxiliary braking.
Technical scheme of the present invention is: comprise vortex induction tube stator, rotor, iron core and power transmission shaft, power transmission shaft links to each other with rotor, stator is positioned at the skin of rotor, in the rotor outside iron core and magnet exciting coil thereof are housed, the permanent magnetism magnetic pole of generator is contained in the rotor inboard, and Blast Furnace Top Gas Recovery Turbine Unit (TRT) armature and coil thereof are connected on the stator fixed mount; In stator interior cooling water channel is set, stator surface is provided with water channel delivery port and water channel water inlet, and this cooling water channel is in communication with the outside with water channel delivery port and water channel water inlet.
The permanent magnetism magnetic pole of Blast Furnace Top Gas Recovery Turbine Unit (TRT) rotor of the present invention is identical with the field pole direction that retarder magnet exciting coil energising back produces, when retarder is braked, the retarder field core produces magnetic field has humidification to the magnetic field that permanent magnetism magnetic pole produces, and improves the generating capacity of electricity generation module.When vehicle was braked slowly, engine load descended, and heat radiation is required also to descend, thereby can directly adopt the cooling fluid in the engine cooling water channel that retarder is cooled off.Design science of the present invention is reasonable, and is simple in structure, can energy savings, improve the generating capacity of rotor machine and the exciting current of retarder, and increase the braking moment and the slow brake efficiency of retarder.
