Description
Technical field
The utility model relates to a kind of auto parts machinery, especially a kind of alternator for vehicle.
Background technology
Collector ring diameter on the existing generator amature is big, and the carbon brush wearing and tearing that contact with collector ring are very fast; Brush and collector ring contact site unprotect easily make dust and metal fragment enter, and make the loose contact at this position, phenomenons such as short circuit stuck and that produce owing to metal fragment.
Existing generator commutation bridge very easily is subjected to Temperature Influence, in hot environment, work, this partly thermal losses will greatly rise and rectifier bridge in life-span of rectifier diode also will shorten greatly.
What existing generator adopted is the mixed type adjuster, and its voltage withstand class of most module (as centrally controrlled locking system, advanced audio etc.) will be far below the mixed type adjuster on the car, so just cause when throw load takes place, adjuster can be escaped by luck, but those equipment more expensive than generator will damage on the contrary.
Existing dynamo belt wheel drive unit exists: excessive slip, belt rock, very big stretcher range of movement, very high problems such as belt tension force level.
Summary of the invention
For realizing the purpose of this utility model, this specification provides a kind of alternator for vehicle improvement project that belt rocks problem that solves.
This alternator for vehicle comprises the rotor of dress, 8 pairs of electrode structures in the minor diameter collector ring, fan; The stator that produces alternating voltage under the rotating magnetic field induction of rotor is 48 groove structure stators; It with ac voltage rectifier the avalanche diode in the rectifier bridge of direct voltage; Multifunction regulator with a plurality of leading foots connects ground, the rotor of generator, the management system of engine, a phase rotor of generator, another phase rotor of generator, the B+ of generator, the indicator light of generator respectively; Pulley gear.
Pulley gear comprises the main pulley of generator input power, the driving wheel that drives whole pulley gear and some auxiliary driven pulleys, idle pulley, automatic tensioner; Main pulley comprises the axle sleeve that is keyed on the axle, the belt pulley that drives belt, protection end cap, and drawn cup and the punching press inner ring of carrying clutch unit secretly are housed between belt pulley and the axle sleeve; Heavy duty double containment fore bearing; Two resin circle bearings.
This alternator for vehicle adopts the path collector ring to can greatly improve the life-span of brush, reduces the maintenance of generator.The collector ring outside diameter is more much smaller than the true footpath of traditional collector ring of generator, rotates a week equally, and the distance that brush is contacted with collector ring will reduce greatly, thereby has reduced the carbon brush wearing and tearing on the brush holder largely.Owing to adopt path collector ring structure, make rear bearing reduce greatly simultaneously in the heavy burden of in rotor high-speed rotates, being born.Cover with sealing shroud at brush and collector ring contact site, make dust and metal fragment be difficult for entering, thereby avoided the loose contact at this position, phenomenons such as short circuit stuck and that produce owing to metal fragment.
Adopt the rectifier bridge external structure then can alleviate problem, main heating position is a stator in the generator, stator and rectifier bridge separate with bonnet in this structure, make a large amount of heat that distributes of stator can not be transmitted to rectifier bridge, guaranteed that rectifier bridge is not subjected to the influence of high temperature, in addition, external to make the operational environment of rectifier bridge no longer be a hermetically-sealed construction that is placed in the bonnet to rectifier bridge.The mobile of air is greatly improved, thus can be instant take away the rectifier bridge heat in when work itself, help the state and the life-time dilatation of rectifier bridge work.
Reduced the load of ball bearing on the motor, reduced the load on the support, have only unidirectional reverse acceleration, when replacing standard rigidity belt pulley, do not need generator is changed, adopts modular system, shorten sample delivery phase and part familyization.
Its belt pulley drive system do not have relevant slip, do not have that belt rocks, very little stretcher range of movement, very low belt tension force level, can satisfy the unbalance requirement of maximum permission.Weakened belt vibration, reduced belt tension, prolonged belt life, reduced stretcher tensile force and displacement, prolonged tensioner life, reduced generator, compared more economical, no natural frequency, prolonged lifetime of system, improved the NVH performance than removing the crank connection to the influence of belt drives, the generator that use has bigger inertia torque, the unidirectional releasing connection mechanism that adopts standard.
Multifunction regulator uses with avalanche diode, the electric equipment on the protection car.Multifunction regulator has soft value-added tax function, when load changes, reduces the velocity variations of engine.When key switch was got to the position of ON, duty ratio of adjuster generation was 17% pre-excitation state.Under this state, generator does not generate electricity or seldom, it is to start easily for engine.
This motor changes the structure of conventional collector ring in the bearing inboard, adopt the stator and rotor new construction, stator adopts 48 grooves, 8 pairs of electrode structures of rotor, large tracts of land heating panel rectifier bridge structure and major diameter, heavily loaded double containment fore bearing, improve the low speed charging performance and the low cruise performance of motor, prolonged the life-span of bearing and motor greatly.
On V348 generator project, adopt complete machine CAE finite element analysis, belt pulley to adopt one-way clutch structure belt wheel, rectifier bridge to adopt avalanche diode, adjuster to adopt multifunction regulator, minor diameter collector ring structure, the fan interior structure of band DFM function.
The purpose of this utility model, feature and advantage will be in conjunction with the embodiments, are further described with reference to accompanying drawing.
