Description
Technical field:
The utility model relates to the electronlmobil field, especially relates to a kind of heat abstractor of Motor for Electric Automobile change speed gear box dynamic assembly.
Background technology:
Electronlmobil is outstanding with performances such as energy-conserving and environment-protective, becomes the important vehicle and make it replace gradually orthodox car.In order further to reduce complete vehicle weight and volume, as dynamic assembly employing high power density motor and the change speed gear box of electronlmobil core component, high power density can cause motor and change speed gear box heat-sinking capability deficiency.Present most power assembly of electric automobile mostly adopts natural air cooled or the Forced water cooling pattern.Adopt the natural air cooled shortcomings such as the not enough and oad of heat-sinking capability is large that exist.Adopt Forced water cooling to have the problem of several aspects: cooling water expansion tank needs the water pump of relatively high power and radiator-water box to carry out water circulation, causes system energy consumption and volume weight to strengthen; The easy corrosion electrical motor shells of cooling water expansion tank etc. cause water to leak; Have incrustation scale to produce, stop up cooling line, its cooling power is descended in addition can make motor because of the deficiency of dispelling the heat occur overheated; Compatible with environment is poor, will prevent pipeline bursting by freezing etc. at cold district, prevents moisture evaporation etc. in the high temperature area.In addition, most of electronlmobil all adopts the high-speed high-power motor, and motor bearings mostly adopts grease lubrication, heat such as untimely the shedding that high rotating speed produces, can make the grease inefficacy and then cause the motor bearings serious wear, and the life-span reduces, and vibration noise strengthens.Air-cooled and the water-cooling structure of traditional natural all is difficult to directly reduce the temperature of rotor bearing.Therefore, a kind of compatible with environment of needs proposition is strong, energy-conservation, volume is little, lightweight heat abstractor.
The utility model content:
The purpose of this utility model is: provide that a kind of compatible with environment is strong, volume is little, the high effect forced air-cooled and oil cooling composite heat dissipation device of lightweight, intelligentized used for electric vehicle dynamic assembly, simple and the low cost of manufacture of this apparatus structure, it is little to consume energy, and reliability easy to maintenance is high.To hundreds of times, heat-sinking capability is powerful than tens times of traditional natural wind-cooling heat dissipating area changes, and power consumption only is ten parts of water-cooling structure.
Technical solution of the present utility model is:
The heat abstractor that a kind of power assembly of electric automobile is used, comprise axial radiation rib, radially radiation rib and extractor fan form, the electric machine main shaft of described dynamic assembly is hollow shaft structure, have a plurality of oil duct grooves that communicate with change speed gear box at the hollow shaft inside face, and the cooling circuit that externally consists of by an oil pump and radiator, continuous cooling motor rotor, thus motor, change speed gear box, rotor-bearing equitemperature reduced; Described axial radiation rib is installed on motor housing, and radially radiation rib is installed on electric motor end cap, forms a plurality of heat dissipation wind channels between radiation rib; Described axial radiation rib is connected by circular air flue with radiation rib radially, dispels the heat by extractor fan.
Described axial radiation rib and radially the cross section of radiation rib be approximate rectangular variable section shape.
Mode of operation and the rotating speed of described extractor fan and oil pump are controlled by temperature controller.
Described radially radiation rib adopts inserting slot construction to be connected with parent with the radiation rib of being connected.
Good effect of the present utility model is: greatly strengthened the radiating effect of motor and change speed gear box, and simple for structure, volume weight is little; Adopt intelligent temperature threshold master mode, the cooling system energy-saving effect is outstanding; By arrange admission port at rotor bearing place, increased the specific heat load at grease lubricating bearing place; Through the rotor hollow shaft, rotor and bearing inner ring temperature have greatly been reduced by gear box oil; Motor one side bearing is communicated with change speed gear box, adopt oil lubrication greatly to improve the motor bearings life-span; Can further improve power density and the overload capacity of dynamic assembly by this cooling system, simultaneously, this cooling system cost is low, simple in structure, energy consumption is little, controllability is strong, environment friendly is strong.
