Abstract
A pot alternating current generator for vehicles is disclosed to improve the heat dissipation effect and decrease the heat loss of the present pot alternating current generator for vehicles, which comprises metallic brush end cap assembly and driving end cap assembly which are connected by through bolt, stator is located between the metallic brush end cap assembly and the driving end cap assembly, rotor is arranged in the stator to match with the stator and installed freely rotating on the metallic brush end cap assembly and driving end cap assembly by rotating shaft, fan is arranged on the external rotation shaft and located between the driving end cap assembly and pulley, the pulley is fixed on the rotating shaft, the particular arrangement lies in that spigot of the metallic brush end cap assembly and driving end cap assembly is provided with a radial air inlet, which is to provide air inlet in the position with highest temperature while generator operating, thereby matching with the stator in order to dissipate heat and improve the heat dissipation effect of the generator and decrease the heat loss, thereby improving efficiency of the generator.
Description
Technical field
The utility model relates to the pot type alternating current generator of vehicle with your formula rotor of Landor.
Technical background:
Existing for motor vehicle pot type alternating current generator is mainly assembled by brush cover, the assembling of driving end cap, Landor that formula rotor, stator, parts such as belt pulley constitute, brush cover and driving end cap link together with in-and-out bolt, stator is fixed on the brush cover assembling and drives between the end cap assembling, rotor and stator are complementary, be positioned at stator, and be installed in the brush cover assembling freely and drive the end cap fit on by rotating shaft rotation, fan is installed in the rotating shaft in the outside, be positioned between assembling of driving end cap and the belt pulley, belt pulley is fixed on the rotating shaft with nut.Described rotor is made of rotor coil and a pair of field core, and 12 claw-type poles that are entrenched togather are mutually arranged on field core.
Described brush cover is assemblied in rear side and has the air inlet through hollow shaft mouth, drives the end cap assembling and has air outlet, and during generator operation, cooling air is flowed into by the air inlet of brush cover assembling, with adjuster, rectifier bridge, rotor, stator, after the bearing cooling, cooling air flows out from the air outlet that drives end cap.
The vehicle-mounted dlternator of said structure, through after the temperature rise test as can be known, the temperature of stator building block (stator core and stator winding) is the highest, but the heat of the alternator frame building block of said structure (iron core and stator winding) can not in time distribute, cause the generator thermal loss big, generator efficiency reduces.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and can not in time cool off when alternator frame that the solution conventional truck is used and heating in winding thereof, and the generator thermal loss is big, the problem that efficient reduces.
The utility model is achieved in that parts such as comprising brush cover assembling, the assembling of driving end cap, rotor, stator, fan, belt pulley constitute, brush cover assembling and the assembling of driving end cap link together with in-and-out bolt, stator is fixed on the brush cover assembling and drives between the end cap assembling, rotor and stator are complementary, be positioned at stator, and be installed in brush cover assembling and drive the end cap fit on by rotating shaft, fan is installed in the rotating shaft in the outside, be positioned between assembling of driving end cap and the belt pulley, belt pulley is fixed on the rotating shaft with nut; Special character has designed radially air inlet respectively at the stop portion of driving end cap assembling that matches with stator and brush cover assembling.
Advantage of the present utility model is, stop portion in driving end cap assembling that matches with stator and brush cover assembling has designed radially air inlet respectively, promptly when generator is worked, its temperature highest point design air inlet, during work, cooling air is by the rear portion air inlet of brush cover, brush cover stop portion air inlet A drives end cap stop portion air inlet B and sucks generator, through the effect of passing through fan, behind the parts of cooling air through generator inside, discharge timely at the air outlet that drives end cap, can effectively dispel the heat, improve the heat-sinking capability of whole generating machine, reduce thermal loss, improve the efficient and the life-span of generator.
