Description

차량용 진공펌프Automotive vacuum pump

일반적으로 차량의 전원공급을 위하여 설치되는 발전기(alternator)에는, 중소형 디젤엔진의 차량에서 브레이크의 작동상 작은 힘으로 큰 힘을 얻기 위하여 발전기와 동축상으로 진공펌프를 설치하고 있으며, 이 진공펌프는 하우징내로 공기를 흡입하고 오일을 공급받아 이들을 베인등으로 압축시키면서 이를 배기구를 통하여 배출하면서 진공력을 발휘하도록 되어 있었다.In general, an alternator installed for power supply of a vehicle is provided with a vacuum pump coaxially with the generator in order to obtain a large force with a small force in brake operation in a vehicle of a small and medium-sized diesel engine. The air was sucked into the housing, and oil was supplied to compress them into vanes and the like, and then discharged through the exhaust port to exert a vacuum force.

한편, 상기와 같이 사용되는 종래의 진공펌프는 흡기구와 배기구가 설치된 펌프하우징내에 베인이 설치된 펌프로터를 설치하며 상기 하우징의 내부로 공기를 흡입하고 오일을 공급받아, 공기와 오일을 상기 펌프로터와 베인으로 순환시키면서 진공력을 발생시키도록 되어 있었고 차량에의 진공력을 제공하도록 되어 있었다.On the other hand, the conventional vacuum pump used as described above is installed in the pump housing, the vane is installed in the inlet and the exhaust port, the pump rotor is sucked air into the housing and supplied with oil, the air and oil and the pump rotor It was designed to generate vacuum while circulating through the vanes and to provide vacuum to the vehicle.

그러나, 상기와 같은 종래의 것은 하우징의 내부에 설치된 펌프로터와 베인이 발전기 축의 회전으로 회전하면서 하우징내로 공급되는 공기와 오일을 단순히 순환시키면서 진공력을 얻을 수 있도록 되어 있었기 때문에 상기 공급되는 오일이 저온에 있을 경우에는 이의 점성 상승으로 인하여 베인의 원심력이 충분히 발휘되지 못하게 되었으며 이에따라 상기 베인과 함께 펌프로터가 제대로 작동되지 못하여 진공력이 발휘되지 못하는 폐단이 있었고 이 진공력의 원활한 제공이 어렵게 되므로써 차량의 초기기동이 불량하게 되는 문제점이 있었다.However, since the pump rotor and vanes installed inside the housing rotate in rotation of the generator shaft to obtain a vacuum force simply by circulating the air and oil supplied into the housing, the supplied oil has a low temperature. In case of, the centrifugal force of the vane could not be fully exerted due to the increase of viscosity. Accordingly, the pump rotor could not be properly operated with the vane, and there was a closed end where the vacuum force could not be exerted. There was a problem that the initial startup is poor.

본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로 흡기구와 배기구가 설치된 펌프 하우징내에 베인이 설치된 펌프로터를 설치하며 상기 펌프로터의 내측에 원통형의 가이드 링을 설치하고 상기 베인들이 이 원통형 가이드 링을 따라 회전하면서 저온상태에서도 상기 진공펌프를 원활하게 작동시키며 우수한 진공력을 발휘할 수 있도록 구성한 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional problems, and installs a pump rotor having vanes in a pump housing provided with an inlet and an exhaust port, and installs a cylindrical guide ring inside the pump rotor, and the vanes have a cylindrical shape. It is configured to operate the vacuum pump smoothly and exhibit excellent vacuum force even in a low temperature state while rotating along the guide ring, which will be described below in detail with reference to the accompanying drawings.

발전기(a)의 축(b)에 흡기구(2)와 배기구(3)가 설치된 펌프 하우징(1)을 설치하고 이의 내부에 베인(5)이 설치된 펌프로터(4)를 설치하며 상기 하우징(1)의 내부에 설치되는 펌프로터(4)의 외측에는 상기 베인(5)들의 내측면이 접촉하면서 외경이 형성되도록 하는 가이드 링(6)을 설치하여 구성된 것으로 7은 급유구이다.A pump housing (1) having an inlet port (2) and an exhaust port (3) is installed on the shaft (b) of the generator (a), and a pump rotor (4) with vanes (5) is installed therein, and the housing (1) is installed. Outside the pump rotor (4) installed in the inner side of the vanes (5) is provided by installing a guide ring (6) to make an outer diameter while the inner surface of the vanes (5) is an oil supply port.

이상과 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

상기 흡기구(2)와 배기구(3)가 설치된 펌프 하우징(1)의 내부에 펌프로터(4)를 설치하고 이 펌프로터(4)에는 상기 베인(5)을 삽입설치하며, 상기 펌프로터(4)의 외측에는 가이드 링(6)을 설치하고 상기 펌프로터(4)가 발전기(a)의 축(b)에 동축상으로 설치되도록하여 조립하고 상기한 상태에서 발전기와 진공펌프를 작동시키면서 사용하도록 한 것으로 제2도에서와 같이 상기 진공펌프가 발전기의 작동에 따라 구동하게 되면, 흡기구(2)를 통하여 공기가 상기 펌프 하우징(1)내로 유입되고 이와 더불어 급유구(7)를 통하여 오일이 상기 하우징(1) 내부로 공급된다.The pump rotor 4 is installed in the pump housing 1 in which the inlet port 2 and the exhaust port 3 are installed. The vane 5 is inserted into the pump rotor 4, and the pump rotor 4 is installed. Guide ring (6) is installed on the outside and the pump rotor (4) is coaxially installed on the shaft (b) of the generator (a) to be assembled and used while operating the generator and vacuum pump in the above state. As shown in FIG. 2, when the vacuum pump is driven according to the operation of the generator, air is introduced into the pump housing 1 through the inlet port 2 and oil is supplied through the oil inlet 7. It is supplied into the housing 1.

상기와 같이 공기와 오일이 하우징(1)내로 유입되면, 상기 발전기에 의하여 작동되는 펌프로터(4)가 구동하게 되고 이에 설치된 베인(5)이 회전하여 상기 공기와 오일을 순환시키게 되는데, 이 공기와 오일은 상기 하우징(1)내에서 압축되면서 배기구(3)를 통하여 배출되며 이때 진공력이 발생된다.When air and oil are introduced into the housing 1 as described above, the pump rotor 4 operated by the generator is driven and the vanes 5 installed therein rotate to circulate the air and oil. The oil and oil are discharged through the exhaust port 3 while being compressed in the housing 1, and a vacuum force is generated at this time.

상기와 같이 흡입, 압축되면서 진공력이 발생되는 본 발명은 진공펌프의 초기기동시나 상기 오일이 저온상태에 있을때는 상기 오일의 점도가 높기 때문에 상기 베인(5)의 원심력이 오일의 점도를 이겨내지 못하여 진공이 형성되지 못하게 되는데, 상기 펌프로터(4)의 외측인 베인(5)의 내측면 위치에 상기 가이드 링(6)을 설치하므로써 상기 베인(5)의 내면이 동일한 지름의 원이 형성되고 상기 베인(5)이 가이드 링(6)의 외경을 따라 회전할 수 있게 되며 이에따라 상기 베인(5)은 오일의 점성과 관계없이 회전하면서 상기 공기와 오일을 압축하고 이를 배기구(3)를 통하여 배출하면서 진공력을 제공하게 되는 것이다.In the present invention in which the vacuum force is generated while being sucked and compressed as described above, the centrifugal force of the vane 5 does not overcome the viscosity of the oil because the viscosity of the oil is high at the initial startup of the vacuum pump or when the oil is at a low temperature. The vacuum is not formed, and by installing the guide ring 6 at the inner side position of the vane 5, which is the outer side of the pump rotor 4, the inner surface of the vane 5 has a circle having the same diameter. The vanes 5 can rotate along the outer diameter of the guide ring 6 so that the vanes 5 rotate, irrespective of the viscosity of the oil, compressing the air and oil and discharging them through the exhaust port 3. It will provide a vacuum force.

이상과 같은 본 발명은 상기와 같이 간단한 구조의 가이드 링(6)을 설치하여 상기 베인(5)이 오일의 저온상태에서도 원활하게 작동될 수 있도록 하므로써, 상기 진공펌프의 초기기동은 물론, 오일의 저온시에도 진공펌프의 작동은 원활하게 되고 양호한 진공력을 제공하면서 발전기의 성능과 특성을 저해하지 않게되는 점 등의 특징을 지닌 것이다.The present invention as described above by installing the guide ring 6 of a simple structure as described above so that the vanes (5) can be operated smoothly even in the low temperature state of the oil, as well as the initial start of the vacuum pump, Even at low temperatures, the operation of the vacuum pump is smooth and provides a good vacuum force while not impairing the performance and characteristics of the generator.

본 발명은 차량에 설치되는 발전기의 일단에 설치되어 이의 작동을 보조하는 발전기용 진공펌프에 관한 것으로 특히, 상기 진공펌프 내에 가이드링을 설치하여 저온에서도 진공펌프의 동작이 신속하고 원활하게 작동될 수 있도록 한 차량용 진공펌프에 관한 것이다.The present invention relates to a vacuum pump for a generator installed at one end of the generator installed in a vehicle to assist the operation thereof, in particular, by installing a guide ring in the vacuum pump can be operated quickly and smoothly even at low temperatures. To a vehicle vacuum pump.
