Abstract
The utility model relates to a generator, in particular to an integral alternating-current generator for a coach. The integral alternating-current generator comprises a front cover, a rear cover, a protective cover, an adjuster, a rectifier bridge, a collecting ring and a heat dissipation structure, wherein the rectifier bridge is arranged on the rear cover, the collecting ring is a small-diameter collecting ring, the heat dissipation structure is arranged between the front cover and the rear cover, and the adjuster, the rectifier bridge and the small-diameter collecting ring are arranged between the rear cover and the protective cover. The integral alternating-current generator is simple in structure, noise generated in operation is reduced, and the service life of the generator is prolonged.
Description
Technical field
The utility model relates to a kind of generator, especially a kind of integral alternator that is used for passenger vehicle.
Background technology
The integral alternator of passenger vehicle comprises electric current to the car load electrical appliance being provided, the alternating current generator of the driving function of tach signal and assistant load being provided for tachometer.The integral alternator that existing way-train is used is generally the structure of external fan blade and adjuster, built-in rectifier bridge and adjuster, major diameter collector ring, and single external fan blade radiating effect and noise are poor with respect to built-in fan blade; And the ambient temperature of built-in rectifier bridge work is more influential to the life-span of rectifier bridge than the height of external; Large diameter collector ring cooperates with carbon brush makes carbon brush not wear-resisting easily, influences the useful life of generator.This generator is the built-in heat radiation of composite type, external rectifier bridge and the adjuster that adopts cast aluminium to combine with the iron winds leaf, the structure of minor diameter collector ring.
Summary of the invention
The utility model is in order to solve defective and the deficiency that above-mentioned prior art exists, provide a kind of simple in structure, noise is little, the integral alternator that is used for passenger vehicle of long service life.
The technical scheme of the utility model: a kind of integral alternator that is used for passenger vehicle; Comprise protecgulum, bonnet, protective cover, adjuster, rectifier bridge, collector ring and radiator structure; Said rectifier bridge is arranged on the bonnet; Said collector ring is the minor diameter collector ring, and said radiator structure places between protecgulum and the bonnet, and said adjuster, rectifier bridge and minor diameter collector ring place between bonnet and the protective cover.
Preferably, said radiator structure by cast aluminium after before fan blade and the irony fan blade cooperatively interact and form.
The built-in heat radiation of composite type that fan blade combines with the preceding fan blade of irony behind this generator employing cast aluminium; Rotation through rotor; To entering, the aperture of opening from the end cap diametric(al) sheds air, and stator end, rectifier diode and adjuster are dispelled the heat from the two end axles of generator; Owing to need not through the air gap between the rotor, so radiating efficiency is able to very big raising.The structure of external rectifier bridge; Negative diode directly is crimped on the bonnet, and positive plate adopts large tracts of land die casting aluminium sheet, reduces the total length of generator on the one hand; Bonnet is exactly a large-area radiator on the other hand, and the heat that can in the short time rectifier diode be produced sheds.Guarantee the low temperature rise of positive negative diode, prolong generator useful life.External adjuster, the operating ambient temperature of reduction adjuster improves radiating effect.The structure of minor diameter collector ring reduces the wearing and tearing of carbon brush and collector ring, prolongation generator useful life.
The integral alternator of the utility model structure, not only simple in structure, and reduced the noise of generation in service, improved and prolonged useful life.
Description of drawings
Fig. 1 is the explosive view of the utility model.
1. adjusters among the figure, 2. rectifier bridge, 3. collector ring, 4. fan blade behind the cast aluminium, 5. fan blade, 6. protective cover, 7. bonnet, 8. protecgulum before the irony.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation, but be not restriction the utility model protection range.
As shown in Figure 1; A kind of integral alternator that is used for passenger vehicle; Comprise protecgulum 8, bonnet 7, protective cover 6, adjuster 1, rectifier bridge 2, collector ring 3 and radiator structure, rectifier bridge 2 is arranged on the bonnet 7, and collector ring 3 is the minor diameter collector ring; Radiator structure places between protecgulum 8 and the bonnet 7, and adjuster 1, rectifier bridge 2 and minor diameter collector ring place between bonnet 7 and the protective cover 6.Radiator structure by cast aluminium after before fan blade 4 and the irony fan blade 5 cooperatively interact and form.
The integral alternator of the utility model structure, not only simple in structure, and reduced noise, improved useful life.
Claims (2)
