본 고안은 자동차용 댐퍼풀리의 러버댐퍼 결합구조에 관한 것으로서, 보다 상세하게는 크랭크축에 고정되어 각종의 보조기기들을 구동시키는 댐퍼풀리에 있어서, 그 내부에 개재되는 러버댐퍼의 이탈과 슬립을 방지하도록 한 자동차용 댐퍼풀리의 러버댐퍼 결합구조에 관한 것이다.The present invention relates to a rubber damper coupling structure of a damper pulley for an automobile, and more particularly, in a damper pulley fixed to a crankshaft to drive various auxiliary devices, to prevent separation and slip of the rubber damper interposed therein. It relates to a rubber damper coupling structure of a damper pulley for automobiles.
일반적으로 자동차의 크랭크축의 풀리는 엔진의 주기적인 비틀림에 따른 진동과 이에 원인한 소음 및 각종의 보기들의 파손을 방지할 목적으로 크랭크축 풀리의 허브에 토셔널 바이브레이션 댐퍼(Tortional Vibration Damper)를 별도로 장치하거나, 또는 이하 본 고안에서 언급될 크랭크축 풀리 자체를 댐핑작용을 하도록 구성한 댐퍼풀리를 구비하고 있다.Generally, the crankshaft pulley of a car is provided with a separate conventional vibration damper in the hub of the crankshaft pulley for the purpose of preventing vibration caused by the periodic twisting of the engine and the noise caused by the crankshaft pulley. Or a damper pulley configured to dampen the crankshaft pulley itself, which will be mentioned in the present invention.
첨부된 도면 제1도는 상기한 댐퍼풀리(2)가 각종의 보기를 구동하는 상태를 나타내는 것으로서, 도시된 바와 같이 크랭크축(도시생략)에 고정되어 회전하는 댐퍼풀리(2)에는 자동차에 전력을 공급하는 알터네이터(4)와, 파워스티어링 유압을 공급하는 파워스티어링펌프(6) 및 에어컨 장치에 구비되는 콤프레서(8)등의 보기가 벨트(10) 연결되게 된다.1 is a view illustrating a state in which the damper pulley 2 drives various views. As illustrated, the damper pulley 2, which is fixed to the crankshaft (not shown) and rotates, supplies electric power to the vehicle. The belt 10 is connected to the alternator 4 for supplying, the power steering pump 6 for supplying the power steering hydraulic pressure, and the compressor 8 provided in the air conditioner.
엔진의 회전에 따라 크랭크축에는 비틀림 진동이 발생하므로 상기 크랭크축에 연결된 상기의 보기들은 주기적인 진동을 받게되어 기기적인 손상 뿐만 아니라 승차감에도 악영향을 미치게 되므로, 상기 보기들을 구동하는 크랭크축의 풀리는 비틀림 진동을 흡수하기 위한 댐퍼풀리의 형태를 적용한 것이다.Torsional vibration occurs on the crankshaft as the engine rotates, and thus, the bogies connected to the crankshaft receive periodic vibrations, which adversely affects riding comfort as well as mechanical damage, so that the torsional vibration of the crankshaft driving the bogies The damper pulley is applied to absorb water.
첨부된 도면 제2도는 상기한 댐퍼풀리(2)의 단면을 나타내는 것으로서, 댐퍼풀리(2)는 크랭크축에 고정되는 허브(12)와, 보기 구동용 벨트(10)가 연결되는 아웃터링(14) 및 상기 허브(12)와 아웃터링(14) 사이에 개재되어 비틀림 진동을 흡수하는 러버댐퍼(16)로 이루어져 있다.2 is a cross-sectional view of the damper pulley 2, wherein the damper pulley 2 has an outer ring 14 to which a hub 12 fixed to the crankshaft and a bogie drive belt 10 are connected. And a rubber damper 16 interposed between the hub 12 and the outer ring 14 to absorb the torsional vibration.
상기한 러버댐퍼(16)는 탄성을 가진 고무재질로서, 독립 구비하여 상기 허브(12)와 아웃터링(14) 사이에 압입하거나, 또는 상기 허브(12)와 아웃터링(14) 사이에 용융상태로 주입하여 형성하기도 한다.The rubber damper 16 is an elastic rubber material, which is independently provided and press-fitted between the hub 12 and the outer ring 14 or in a molten state between the hub 12 and the outer ring 14. It may be formed by injection.
상기한 러버댐퍼(16)는 비틀림과 진동을 받기 때문에 상기 허브(12)와 아웃터링(14) 사이에서 슬립하거나, 또는 이탈되어 버리는 일이 발생하였다.Since the rubber damper 16 is subject to torsion and vibration, the rubber damper 16 slips or slips off between the hub 12 and the outer ring 14.
이러한 문제 때문에 도시된 단면이 플랫트한 예와는 달리 종래에는 상기 허브(12)와 아웃터링(14)의 소정부에 원주를 따라 돌기를 형성하였으나, 이것은 단순히 접촉면적을 약간 증가시키는 역할만 할 뿐 그다지 향상되는 효과를 거두지 못하였다.Due to this problem, unlike the example in which the illustrated cross section is flat, a protrusion is formed along a circumference in a predetermined portion of the hub 12 and the outer ring 14, but this merely serves to slightly increase the contact area. Not only did not improve the effect.
본 고안은 상기와 같은 문제를 해소하기 위하여 안출된 것으로서, 허브와 아웃터링에 세레이션을 형성한 자동차용 댐퍼풀리의 러버댐퍼 결합구조를 제공하여 러버댐퍼의 슬립과 이탈을 방지할 수 있도록 하는데 그 목적이 있다.The present invention was devised to solve the above problems, and provides a rubber damper coupling structure of a damper pulley for automobiles in which a serration is formed in the hub and the outer ring to prevent slipping and slipping of the rubber damper. There is a purpose.
상술한 목적을 달성하기 위하여 본 고안에 따른 자동차용 댐퍼풀리의 러버댐퍼 결합구조는 허브의 외측과 아웃터링의 내측에 세레이션을 형성하여, 그 사이에 러버댐퍼를 주입하여 일체로 성형한 것을 특징으로 한다.In order to achieve the above object, the rubber damper coupling structure of the damper pulley for automobiles according to the present invention is formed by forming a serration on the outer side of the hub and the inner side of the outer ring and injecting the rubber damper therebetween to form a molded body. It is done.
이하, 첨부된 도면 제3도를 참조하여 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIG. 3.
제3도는 본 고안에 따른 댐퍼풀리의 러버댐퍼 결합구조를 나타내는 것으로서, 크랭크축에 고정되며, 그 외측에 세레이션(32)이 형성된 허브(30)와, 각종의 보기들과 벨트 연결되며, 그 내측에 세레이션(42)이 형성된 아웃터링(40)과, 상기 허브(30)와 아웃터링(40)의 세레이션(32,42) 사이에 주입되는 러버댐퍼(50)가 일체로 결합된 구성으로 이루어진다.Figure 3 shows the rubber damper coupling structure of the damper pulley according to the present invention, is fixed to the crankshaft, the hub 30, the serration 32 is formed on the outside thereof, the belt is connected to various bogies, The outer ring 40 having the serration 42 formed therein and the rubber damper 50 injected between the hub 30 and the serrations 32 and 42 of the outer ring 40 are integrally combined. Is done.
상기 러버댐퍼(50)는 상기 허브(30)와 아웃터링(40)을 소정의 금형에서 용융상태로 주입하여 일체로 성형하는 것이 제조상 및 결합특성상 바람직하다.Preferably, the rubber damper 50 is integrally formed by injecting the hub 30 and the outer ring 40 in a molten state in a predetermined mold and integrally molded.
본 고안에 따른 자동차용 댐퍼풀리의 러버댐퍼 결합구조는 상기와 같이 이루어져 있기 때문에 각종의 보기를 구동할 경우에 허브(30)와 아웃터링(40)에 비틀림이 발생하면, 상기 러버댐퍼(50)는 상기 허브(30)와 아웃터링(40)의 세레이션(32,42)에 결합되어 회전방향으로 구속되어 있기 때문에 댐핑작용에 요구되는 자체의 탄성에 의한 미량의 비틀림만 발생하고 종래에 있어서와 같은 슬립은 발생치 않으며 또한, 세레이션(32,42)은 그 접촉면적을 크게 증대시키는 역할을 하므로 축방향으로의 이탈 가능성이 더욱 배제되는 것이다.Since the rubber damper coupling structure of the damper pulley for automobiles according to the present invention is configured as described above, when a twist occurs in the hub 30 and the outer ring 40 when driving various views, the rubber damper 50 is provided. Since it is coupled to the serrations 32 and 42 of the hub 30 and the outer ring 40 and constrained in the rotational direction, only a small amount of torsion due to its elasticity required for damping action occurs. The same slip does not occur, and since the serrations 32 and 42 serve to greatly increase the contact area, the possibility of deviation in the axial direction is further excluded.
