Description

차량용 교류발전기{Alternator for vehicle}Alternator for Vehicle

본 발명은 차량용 교류발전기에 설치된 전후방브라켓트에 각각의 냉각수로를 형성하고 상기 후방브라켓트에는 코어를 고정시키고 필드코일을 상기 필드코어에 설치하며 브러시와 슬립링을 설치하지 않은 상태에서 필드코일을 여자시킬 수 있도록 한 차량용 교류발전기에 관한 것이다.The present invention forms the respective cooling water passages in the front and rear brackets installed in the vehicle alternator, and the cores are fixed to the rear brackets, the field coils are installed on the field cores, and the field coils are excited without the brush and slip ring installed. A vehicle alternator is provided.

일반적으로 차량에는 각종 전기 및 전자기기를 장착하고 이들은 발전기와 축전지로부터 공급되는 전력에 의하여 작동되도록 되어 있으며, 상기 전력의 안정된 공급을 위하여 발전기를 중심으로 하는 충전장치를 구비하고 있고, 상기 발전기는 직류발전기와 교류발전기가 이용되고 있으나, 저속 및 고속에서도 안정성을 유지하는 교류발전기가 보다 널리 이용되고 있으며 이는 하우징의 내부에 브러쉬 어셈블리, 스테이터 어셈블리, 로터 어셈블리 및 베어링과 풀리 등으로 구성되어 있다.In general, the vehicle is equipped with a variety of electrical and electronic devices and they are to be operated by the power supplied from the generator and the storage battery, and is provided with a charging device centered on the generator for the stable supply of the power, the generator is a direct current Generators and alternators are used, but alternators that maintain stability even at low and high speeds are more widely used, which consists of a brush assembly, stator assembly, rotor assembly, bearings and pulleys inside the housing.

한편, 상기와 같이 구성된 종래의 것은 교류발전기가 구동되면, 자화된 로터가 회전하면서 상기 스테이터코일에 3상 교류의 유기전압이 발생되고 이를 차량의 밧데리충전과 각종 전기부하에 직류전원을 공급하기 위한 정류기와 전압조정기에 의해 정류되며 이 정류된 전원을 차량에 공급하도록 되어 있었다.On the other hand, the conventional configuration configured as described above, when the alternator is driven, the induced voltage of the three-phase alternating current is generated in the stator coil while the magnetized rotor rotates to supply the DC power to the battery charging of the vehicle and various electric loads. It was rectified by a rectifier and a voltage regulator, and the rectified power was to be supplied to the vehicle.

또, 상기와 같이 발전기 작동시 발생하는 열을 냉각시키기 위해서 풀리의 내측에 팬(Fan)을 설치하거나 상기 스테이터 어셈블리의 정류기 또는 슬립링 일방이나, 로터의 폴에 냉각팬을 설치하고 이 팬의 동작으로 발생된 냉각풍이 상기 교류발전기의 내부를 순환하면서 냉각작용을 하는 공냉식으로 되어 있었다.In addition, in order to cool the heat generated during the operation of the generator as described above, a fan is installed inside the pulley or one of the rectifiers or slip rings of the stator assembly or a cooling fan is installed in the pole of the rotor to operate the fan. The cooling wind generated by the air circulation was air-cooled to circulate the inside of the alternator to perform a cooling action.

그러나, 상기와 같은 종래의 것은 냉각팬을 이용한 공냉식으로 구성되어 있었기 때문에 상기 냉각팬을 설치하기 위한 구조가 복잡하게 되어 있었고 또, 구조의 복잡성으로 인하여 발전기 전체의 부피가 커지게 되는 폐단이 있었으며, 상기 냉각팬의 구동에 의한 바람이 회전체에 부딪히면서 풍음을 발생시키게 되어 발전기의 구동시 소음이 발생하게 되는 문제점이 있었고 또한, 엔진 등의 열에 의한 엔진룸의 열이 비교적 고열이기 때문에 상기 공냉을 위한 공기가 자체의 열로 인해 충분한 냉각기능을 발휘하기 어렵게 되어 냉각효율이 크게 저하되고 있는 점 등의 문제점이 있었다.However, since the conventional one is composed of air cooling using a cooling fan, the structure for installing the cooling fan is complicated, and due to the complexity of the structure, there is a closed end in which the entire volume of the generator is increased. The wind caused by the driving of the cooling fan hits the rotating body to generate wind noise, there was a problem that the noise generated when driving the generator, and because the heat of the engine room by the heat of the engine is relatively high heat for the air cooling There is a problem that the air is difficult to exhibit a sufficient cooling function due to its own heat, and the cooling efficiency is greatly reduced.

본 발명은 상기와 같은 종래의 제반 결점을 감안하고 이를 해소하기 위하여 안출한 것으로, 상기 차량용 교류발전기에 설치된 전후방브라켓트에 각각의 냉각유로를 형성하고 상기 후방브라켓트에는 필드코어를 고정시키고 필드코일을 상기 필드코어에 설치하며 브러시와 슬립링을 설치하지 않은 상태에서 필드코일을 여자시킬 수 있도록 한 차량용 교류발전기를 제공하려는 것인바, 이를 이하에서 첨부한 도면과 실시예에 의거하여 상세하게 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional drawbacks and solves the above-mentioned problems. Each cooling flow path is formed on the front and rear brackets installed in the vehicle alternator, and the field cores are fixed to the rear brackets and the field coils are fixed. It is intended to provide an automotive alternator installed on a field core and to excite a field coil without installing a brush and slip ring, which will be described below in detail with reference to the accompanying drawings and examples. same.
