본 고안은 차량(vehicle)에 관한 것으로서, 더욱 상세하게는 소음이 감소되도록 한 차량용 크랭크샤프트(crankshaft)의 댐퍼 풀리 조립체(damper pulley assembly)에 관한 것이다.The present invention relates to a vehicle, and more particularly, to a damper pulley assembly of a crankshaft for a vehicle to reduce noise.
일반적으로 차량은 엔진(engine)의 동력을 이용하여 도로(road)를 주행하는 것으로, 차량의 구조는 기능적으로 크게 주행에 필요한 장치를 구비한 새시(chassis)와, 사람이나 화물을 수용하기 위한 보디(body)로 나눌 수 있다.In general, a vehicle travels on a road by using an engine power, and the structure of the vehicle is a chassis that has a device that is largely functional for driving and a body for accommodating people or cargo. Can be divided into (body).
엔진의 동력은 피스톤(pistone)의 왕복운동이 크랭크샤프트의 작동에 의해 회전운동으로 전환된는 것이며, 크랭크샤프트의 댐퍼 풀리는 주요한 기능으로 알터네이터(alternator) 및 워터 펌프(water pump), 파워 스티어링 펌프(power steering pump)등과 같이 엔진 주변부품을 구동시키는 역할과, 크랭크샤프트에서 발생하는 비틀림 진동을 억제해주는 기능을 갖고 있다.The power of the engine is that the reciprocating motion of the piston is converted to rotational motion by the operation of the crankshaft, and the damper release of the crankshaft is the main function of alternator, water pump and power steering pump. It has the role of driving the engine peripheral parts such as steering pump, etc., and suppresses the torsional vibration generated from the crankshaft.
특히, 피스톤(piston)의 왕복운동을 회전운동으로 전환시켜주는 크랭크샤프트의 경우 댐퍼 풀리에 의한 비틀림 진동의 억제는 소음감소와 연결되어 중요한 요소(factor)로서 작용하게 된다.In particular, in the case of the crankshaft that converts the reciprocating motion of the piston into the rotary motion, the suppression of the torsional vibration by the damper pulley acts as an important factor in connection with the noise reduction.
이와 같은 종래 차량용 크랭크샤프트의 댐퍼 풀리 조립체를 제1도에 나타내어 설명한다.The damper pulley assembly of such a conventional vehicle crankshaft is shown in FIG. 1 and demonstrated.

댐퍼 풀리(11)의 풀리(12)는 엔진 주변부품, 예를 들어 알터네이터 및 워터 펌프등을 구동시키기 역할을 수행한다.The pulley 12 of the damper pulley 11 serves to drive engine peripheral parts such as an alternator and a water pump.
그리고, 크랭크샤프트(10)의 한쪽에 댐퍼 풀리(11)와 함께 에어콘 풀리(air conditioner pulley: 13)가 장착된다.Then, an air conditioner pulley 13 is mounted on one side of the crankshaft 10 together with the damper pulley 11.
그러나, 상기한 바와 같이 종래 차량용 크랭크샤프트의 댐퍼 풀리 조립체는, 크랭크샤프트(10)의 전방 끝에 장착되는 댐퍼 및 에어콘 풀리(11)(13)가 엔진의 전방으로 열려진 구조로 이루어짐으로써, 이들의 구동시 발생되는 소음이 외부로 노출되어 신뢰성이 저하되는 원인으로 작용되는 문제점이 있었다.However, as described above, the damper pulley assembly of the crankshaft for a conventional vehicle has a structure in which the damper and air conditioner pulleys 11 and 13 mounted at the front end of the crankshaft 10 are opened to the front of the engine, thereby driving them. There was a problem that the noise generated during the exposure to the outside acts as a cause of lowering reliability.
본 고안은 상기한 바와 같은 종래의 제반 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 댐퍼 풀리에 에어콘 풀리부가 일체형으로 구성되어 제품의 생산비용이 절감될 뿐만 아니라, 플럭에 의해 엔진의 전방이 닫혀진 구조로 이루어져 소음이 차단되므로, 제품의 신뢰성이 향상되도록 한 차량용 크랭크샤프트의 댐퍼 풀리 조립체를 제공하는데 있다.The present invention has been devised to solve the conventional problems as described above, the object of the present invention is that the damper pulley is composed of an air-conditioning pulley unit integrally reduced production cost of the product, as well as the front of the engine by the floc The closed structure is made of a noise block, to provide a damper pulley assembly of a vehicle crankshaft to improve the reliability of the product.
이와 같은 목적을 달성하기 위한 본 고안의 특징은, 피스톤의 왕복운동을 회전운동으로 전환시켜주는 크랭크샤프트의 비틀림 진동을 억제해 주는 차량용 크랭크샤프트의 댐퍼 풀리 조립체에 있어서, 댐퍼 풀리의 허브부에 에어콘 풀리부가 일체형으로 형성되고, 상기 댐퍼 풀리의 에어콘 풀리부에 소음이 감소되도록 플럭이 일체로 형성되는 차량용 크랭크샤프트의 댐퍼 풀리 조립체에 있다.In order to achieve the above object, a feature of the present invention is a damper pulley assembly of a crankshaft for a vehicle that suppresses torsional vibration of a crankshaft that converts a reciprocating motion of a piston into a rotational motion. The damper pulley assembly of the vehicle crankshaft is formed integrally with the pulley portion, the flock is integrally formed so that the noise is reduced in the air conditioner pulley portion of the damper pulley.
이하, 본 고안에 따른 차량용 크랭크샤프트의 댐퍼 풀리 조립체에 대한 하나의 바람직한 실시예를 첨부된 도면에 의거하여 상세하게 설명한다.Hereinafter, a preferred embodiment of a damper pulley assembly of a vehicle crankshaft according to the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안에 따른 차량용 크랭크샤프트의 댐퍼 풀리 조립체를 설명하기 위하여 나타낸 도면이다.2 is a view showing for explaining the damper pulley assembly of the vehicle crankshaft according to the present invention.
제2도에 나타낸 바와 같이, 크랭크샤프트(20)의 전방 끝에 댐퍼 풀리(21)가 장착되고, 댐퍼 풀리(21)는 허브부(hub part : 22)가 일체로 형성된다.As shown in FIG. 2, a damper pulley 21 is mounted at the front end of the crankshaft 20, and the damper pulley 21 is formed with a hub part 22.
한편, 댐퍼 풀리(21)의 외주면에 풀리(23)가 장착되며, 댐퍼 풀리(21)의 풀리(23)는 엔진 주변부품, 예를 들어 알터네이터 및 워터 펌프등을 구동시키기 역할을 수행한다.On the other hand, the pulley 23 is mounted on the outer circumferential surface of the damper pulley 21, the pulley 23 of the damper pulley 21 serves to drive the engine peripheral parts, for example, the alternator and the water pump.
그리고, 댐퍼 풀리(21)는 허브부(22)의 한쪽 면에 에어콘 풀리부(air conditioner pulley part : 24)가 일체형으로 형성되며, 에어콘 풀리부(24)의 내면에 플럭(plug : 25)이 형성된다.In addition, the damper pulley 21 has an air conditioner pulley part 24 formed integrally on one side of the hub 22, and a plug 25 is formed on an inner surface of the air conditioner pulley 24. Is formed.
따라서, 본 고안에 따른 차량용 크랭크샤프트의 댐퍼 풀리 조립체는, 댐퍼 풀리(21)의 허브부(22)에 에어콘 풀리부(24)가 일체형으로 구성됨으로써, 댐퍼 풀리(21)의 제작이 용이해질 뿐만 아니라, 제품의 생산비용이 현저하게 감소된다.Accordingly, in the damper pulley assembly of the vehicle crankshaft according to the present invention, the air conditioner pulley part 24 is integrally formed with the hub part 22 of the damper pulley 21, thereby facilitating the manufacture of the damper pulley 21. In addition, the production cost of the product is significantly reduced.
또한, 크랭크샤프트(20)의 전방 끝에 장착되는 댐퍼 풀리(22)의 에어콘 풀리부(24)에 플럭(25)이 형성되어 엔진의 전방이 닫혀지는 구조로 이루어짐으로써, 이들의 구동시 발생되는 소음이 차단되어 제품의 신뢰성이 크게 향상된다.In addition, since the floc 25 is formed in the air conditioner pulley part 24 of the damper pulley 22 mounted at the front end of the crankshaft 20, the front of the engine is closed, so that noise generated when driving the engine is closed. This blockage greatly improves the reliability of the product.
한편, 상기한 실시예는 본 고안의 바람직한 하나의 실시예를 설명한 것에 불과하고, 본 고안의 적용범위는 이와 같은 것에 한정되는 것은 아니며 동일사상의 범주내에서 적절하게 변경가능한 것으로, 예를 들면 구동력을 전달하는 각종 풀리에 널리 적용할 수 있는 것이다.On the other hand, the above embodiment is merely to describe one preferred embodiment of the present invention, the scope of application of the present invention is not limited to such, and can be changed appropriately within the scope of the same thought, for example driving force It is widely applicable to a variety of pulleys that deliver.
이상에서와 같이 본 고안에 따른 차량용 크랭크샤프트의 댐퍼 풀리 조립체에 의하면, 댐퍼 풀리에 에어콘 풀리부가 일체형으로 구성되므로, 제품의 생산비용이 현저히 절감되는 것이다. 또한, 풀리에 의해 엔진의 전방이 닫혀진 구조로 이루어져 소음이 차단되므로, 제품의 신뢰성이 크게 향상되는 것이다.As described above, according to the damper pulley assembly of the vehicle crankshaft according to the present invention, since the air conditioner pulley unit is integrally formed on the damper pulley, the production cost of the product is significantly reduced.
